Foreword
Organized in 1898, ASTM has grown into one of the largest voluntary standards development systems in the world. ASTM is a not-for-profit organization which provides a forum for producers, users, ultimate consumers, and those having a general interest (representatives of government and academia) to meet on common ground and write standards for materials, products, systems, and services.
From the work of 134 standards-writing committees, ASTM publishes more than 8,500 standards each year. These standards and other related technical information are sold throughout the world.
ASTM Headquarters has no technical research or testing facilities; such work is done voluntarily by 33,000 technically qualified ASTM members located throughout the world. Membership in the Society is open to all concerned with the fields in which ASTM is active. A membership application may be found at the back of this volume. Additional information may be obtained from Member and Committee Services, ASTM, 1916 Race St., Philadelphia, PA 19103; tel. (215) 299-5454.
1992 Annual Book of ASTM Standards The 1992 Annual Book ofASTM Standards consists of 68 volumes, divided among 16 sections, ofwhich this
volume is one. It contains approved ASTM standards, proposals, emergency standards, and related material. These terms are defined as follows in the Regulations Governing ASTM Technical Committees:
Categories: standard--as used in ASTM, a document that has been developed and established within the consensus
principles of the Society and that meets the approval requirements of ASTM procedures and regulations. Discussion--The term "standard" serves in ASTM as an adjective in the title of documents, such as test
methods or specifications, to connote specified consensus and approval. The various types of standard documents are based on the needs and usages as prescribed by the technical committees of the Society.
proposal--a document that has been approved by the sponsoring committee for publication for information and comment prior to its consideration for adoption as a standard.
Discussion--Complete balloting procedures are not required for proposals.
emergency standard--a document published by the Society to meet a demand for more rapid issuance of a specific standard document.
Discussion--The Executive Subcommittee of the sponsoring committee must recommend the publishing of an emergency standard and the Committee on Standards must concur in the recommendation. Emergency standards are not full consensus documents because they are not submitted to Society ballot
Types: The various types of ASTM documents are to provide a flexibility of form, communication, and usage for
both the technical committees and the myriad users of ASTM documents. The type of ASTM document that is developed and titled is based on the technical content and intended use, not on the degree of consensus achieved. The three categories ofASTM documents (standard, emergency standard, and proposal) can be ofthe following forms and types:
classification--a systematic arrangement or division of materials, products, systems, or services into groups based on similar characteristics such as origin, composition, properties, or use.
guide--a series of options or instructions that do not recommend a specific course of action. Discussion--Whereas a practice prescribes a general usage principle, a guide only suggests an approach. The purpose of a guide is to offer guidance, based on a consensus of viewpoints, but not to establish a fixed procedure. A guide is intended to increase the awareness of the user to available techniques in a given subject area and to provide Information from which subsequent evaluation and standardization can be derived.
in
DUP050297155
practice--a definitive procedure for performing one or more specific operations, or functions that does not-- produce a test result. (Compare test method.)
Discussion--A practice is not a downgraded test method. Examples of practices include procedures for conducting interlaboratory testing programs or other statistical procedures; for writing statements on sampling or precision and bias; and for selection, preparation, application, inspection, necessary precautions for use or disposal, installation, maintenance, and operation of testing equipment.
specification--a precise statement of a set of requirements to be satisfied by a material, product, system, or service that indicates the procedures for determining whether each of the requirements is satisfied.
Discussion--It is desirable to express the requirements numerically in terms of appropriate units together with their limits.
terminology--a document comprising definitions of terms; descriptions of terms; and explanations of symbols, abbreviations, or acronyms.
test method--a definitive procedure for the identification, measurement, and evaluation of one or more qualities, characteristics, or properties of a material, product, system, or service that produces a test result. (Compare practice.)
A new edition of the Book of Standards is published annually because of additions of new standards and significant revisions to existing standards. Approximately 30 % of each volume is new or revised. Each volume contains all actions approved by the Society at least six months before the publication date. New and revised standards approved by the Society between the annual editions of any given volume are made available as separate copies. Users are cautioned to follow the most current issue of a standard except when a specific edition of a standard is cited, for example, as in a contract.
Development and Use of ASTM Standards
ASTM believes that technically competent standards result when a full consensus of all concerned parties is achieved and rigorous due process procedures are followed. This philosophy and standards development system ensure technically competent standards having the highest credibility when critically examined and used as the basis for commercial, legal, or regulatory actions.
ASTM standards are developed voluntarily and used voluntarily. Standards become legally binding only when a government body references them in regulations, or when they are cited in a contract. Any item that is produced and marked as conforming to an ASTM standard must meet all applicable requirements of that standard.
ASTM standards are used by thousands of individuals, companies, and agencies. Purchasers and sellers incorporate standards into contracts; scientists and engineers use them in laboratories; architects and designers use them in plans; government agencies reference them in codes, regulations, and laws; and many others refer to standards for guidance.
Consideration of Comments on ASTM Standards
An ASTM standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. Your comments are invited either for revision of any standard or for additional standards and should be addressed to ASTM Headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. If you feel that your comments have not received a fair hearing you should make your views known to die ASTM Committee on Standards, 1916 Race St., Philadelphia, PA 19103.
Using the Annual Book of ASTM Standards
The standards are assembled in each volume in alphanumeric sequence of their ASTM designation numbers except for Volumes 11.01,11.02, and 05.04, which are assembled by subject matter. Volumes 05.03 and 06.03 are assembled first by committee, then in alphanumeric sequence. Each volume has a table of contents, listing the standards in alphanumeric sequence by ASTM designation; and a list by subjects, categorizing the standards according to subject. A subject index of the standards in each volume appears at the back of each volume.
Availability of Individual Standards
Each ASTM standard is available as a separate copy from ASTM. Special quantity prices and discounts can be obtained from Customer Services. When ordering, provide the ASTM standard designation and year of issue, title, quantity desired, and shipping instructions.

Caveat Statements and Policies In Standards ASTM caveat statements on Safety Hazards and Fire Hazards are required to appear in standards where
appropriate. They are located in the scope section of applicable standards. The caveats on General Statement of ASTM Policy and Patents are contained in all standards and located at the end ofeach standard disclaimer. For more information on the caveats see Section F2 of the Form and Style Manual for ASTM Standards.

This contents includes only those standards included in these books and those standards that appeared previously that have been superceded or discontinued within the past five'years. Since the standards in these books are arranged in alphanumerical sequence, no page numbets are given in this contents.
The alphanumerical sequence in Volume 06.03 is divided into two sections, separating the standards of Committee D-l and D-16.
In the serial designations prefixed to the following titles, the number following the dash indicates the year of original adoption as standard or, in the case bf revision, the year of last revision. Thus, standards adopted or revised during the year 1992 have as their final number, 92. A letter following' this number indicates more than one revision during that year, that is 92a indicates the second revision in 1992, 92b the third revision, etc. Standards that have been reapproved without change are indicated by the year of last reapprovai in parentheses as part of the designation number, for example, (1992). A superscript epsilon indicates an editorial change since the last revision or reapproval--el for the first change, e2 for the second change, etc.

1. Scope
1.1 This test method sets forth the conditions required in salt spray (fog) testing for specification purposes. Suitable apparatus which may be used to obtain these conditions is described in Appendix XI. The method does not prescribe the type oftest specimen or exposure periods to be used for a specific product, nor the interpretation to be given to tbe results. It should be noted that there is seldom a direct relation between salt spray (fog) resistance and resistance to corrosion in other media, because the chemistry of the reactions, including the formation of films and their protec tive value, frequently varies greatly with the precise condi tions encountered. Comments on the use of the test in research will be found in Appendix X2. For evaluation of corrosive conditions, see Appendix X3.
NNO' 1--This method is applicable to salt spray (fog) testing' of
ferrous and nonferrous metals, and is also used to test inorganic and organic coatings, etc., especially where such tests are the basis formaterial or product specifications.
1.2 The values stated in SI units are to be regarded as standard. The inch-pound units in parentheses are provided for information.
1.3 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport toaddress all ofthe safetyproblems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

5.2 Specimens for evaluation of paints and other organic Ratings shall be prepared in accordance with applicable gpecification(s) for the materials) being tested, or as agreed upon by the purchaser and supplier. Otherwise, the test specimens shall consist of steel meeting the requirements of Methods D609 and shall be cleaned and prepared for coating in accordance with applicable procedure of Methods D 609.
5.3 Specimens coated with paints or nonmetallic coatings shall not be cleaned or handled excessively prior to test.
5.4 Whenever it is desired to determine the development of corrosion from an abraded area in the paint or organic coating, a scratch or scribed line shall be made through the coating with a sharp instrument so as to expose the under lying metal before testing. The conditions of making the scratch shall be as defined in Method D 1654, unless otherwise agreed upon between the purchaser and seller.
5.5 Unless otherwise specified, the cut edges of plated, coated, or duplex materials and areas containing identifica tion marks or in contact with the racks or supports shall be protected with a suitable coating stable under the conditions of the test, such as ceresin wax.
NPQ' 2--Should it be desirable to cut test specimens from parts or
from preplated, painted, or otherwise coated steel sheet, the cut edges shall be protected by coating them with paint, wax, tape, or other, effective media so that the development of a galvanic effect between such edges and the adjacent plated or otherwise coated metal surfaces, is prevented.
6. Position of Specimens During Test
6.1 The position of the specimens in the salt spray chamber during the test shall be such that the following conditions are met
6.1.1 Unless otherwise specified, the specimens shall be supported or suspended between 15 and 30 from the vertical and preferably parallel to the principal direction of hori zontal flow of fog through the chamber, based upon the dominant surface being tested.
6.1.2 The specimens shall not contact each other or any metallic material or any material capable of acting as a wick.
6.1.3 Each specimen shall be so placed as to permit free settling of fog on all specimens.
6.1.4 Salt solution from one specimen shall not drip on any other specimen.
NRS' 3--Suitable materials for the construction or coating of racks
and supports are glass, rubber, plastic, or suitably coated wood. Bare metal shall not be used. Specimens shall preferably be supported from the bottom or the side. Slotted wooden strips are suitable for the support offlat panels. Suspension from glass hooks or waxed string may be used as long as the specified position ofthe specimens is obtained, ifnecessary by means of secondary support at the bottom of the specimens.
7. Salt Solution
7.1 The salt solution shall be prepared by dissolving 5 1 parts by weight of sodium chloride in 95 parts of water conforming to Type IV water in Specification D 1193. The salt used shall be sodium chloride substantially free of nickel and copper and containing on the dry basis not more than 0.1 % of sodium iodide and not more than 0.3 % of total
impurities. Some salts contain additives that may act as
corrosion inhibitors; careful attention should be given to the
chemical content of the salt. Upon agreement between
purchaser and seller, analysis may be required and limits
established for elements or compounds not
^^
chemical composition given above.
7.2 The pH of the salt solution shall be such that when
atomized at 35C (95F) the collected solution will be in the
pH range of 6.5 to 7.2 (Note 4). Before the solution is
atomized it shall be free of suspended solids (Note 5). The
pH measurement shall be made electrometrically at 25C (77F) using a glass electrode with a saturated potassium
chloride bridge in accordance with Method E70, or colorimetrically using bromothymol blue as indicator, or
short range pH paper which reads in 0.2 or 0.3 of a pH unit (Note 6).
NTU' 4--Temperature affects the pH of a salt solution prepared
from water saturated with carbon dioxide at room temperature and pH adjustment may be made by the following three methods:
(f) When the pH of a salt solution is adjusted at room temperature and atomized at 35C (95F), the pH of the collected solution will be higher than the original solution due to the loss ofcarbon dioxide at the highertemperature. When the pH ofthe salt solution is adjusted at room temperature, it is therefore necessary to adjust it below 6.5 so the collected solution after atomizing at 35*C (95'F) will meet the pH limits
of6.5 to 7.2. Take about a 50-mL sample ofthe salt solution as prepared at room temperature, boil gently for 30 s, cool, and determine the pH. When the pH of the salt solution is adjusted to 6.5 to 7.2 by this procedure, the pH ofthe atomized and collected solution at 35"C (95'F) will come within this range.
(2) Heating the salt solution to boiling and cooling to 95'F for maintaining it at 95'F for approximately 48 h before adjusting the pH produces a solution the pH of which does not materially change when atomized at 35C (95'F).
(5) Heating the water from which the salt solution is prepared to 35'C (95"F) or above, to expel catbon dioxide, and adjusting the pH of the salt solution within the limits of 6.5 to 7.2 produces a solution the pH of which does not materially change when atomized at 35'C (95'F).
NVW' 5--The freshly prepared salt solution may be filtered or
decanted before it is placed in the reservoir, or the end of the tube
leading from the solution to the atomizer may be covered with a double
layer of cheesecloth to prevent plugging of the nozzle.
NVW' 6--The pH can be adjusted by additions of dilute cp hydro
chloric acid or cp sodium hydroxide solutions.
8. Air Supply
8.1 The compressed air supply to the nozzle or nozzles few atomizing the salt solution shall be free of oil and dirt (Note 7) and maintained between 69 and 172 kN/m2 (10 and 25
psi) (Note 8).
NTU' 7--The air supply may be freed from oil and dirt by passing it
trough a water scrubber or at.legst 610 mm (2 ft) of suitable cleaning laterial such as sheep's wool, excelsior, slag wool, or activated
iuNmViWn'a.S--Atomizing nozzles may have a "critical pressure" at which
n abnormal increase in the corrosiveness of the salt fog occurs. If the :ritical pressure" of a nozzle has not been established with certainty jntrol of fluctuation in the air pressure within plus orminus 0.7 kN/nr ).l psi), by installation of a suitable pressure regulator valve mint-

mizes the possibility that the nozzle will be operated at its "critical pressure."9
9. Conditions in the Salt Spray Chamber
9.1 Temperature--The exposure zone of the salt spray chamber shall be maintained, at 35 + 1.1 - 1.7'C (95 + 2 -- 3'F). The temperature within the exposure zone ofthe closed cabinet shall be recorded at least twice a day at least 7 h apart (except on Saturdays, Sundays, and holidays when the salt spray test is not interrupted for exposing, rearranging, or removing test specimens or to check and replenish the solution in the reservoir).
NXY' 9--A suitable method to record the temperature is by a
continuous recoiding device or by a thermometer which can be read from outside the closed cabinet. The recorded temperature must be obtained with the salt spray chamber to avoid a false low reading because of wet-bulb effect when the chamber is open.
9.2 Atomization and Quantity ofFog--At least two clean fog collectors shall be so placed within the exposure zone that no drops of solution from the test specimens or any other source shall be collected. The collectors shall be placed in the proximity of the test specimens, one nearest to any nozzle and the other farthest from all nozzles. The fog shall be such that for each 80 cm2 of horizontal collecting area there will be collected in each collector from 1.0 to 2.0 mL of solution per hour based on an average run of at least 16 h (Note 10). The sodium chloride concentration of the collected solution shall be 5 1 weight % (Note 11). The pH of the collected solution shall be 6.5 to 7.2. The pH measurement shall be made electrometrically or colorimetrically using bromothymol blue as the indicator.
NZ[' 10--Suitable collecting devices are glass funnels with the stems
inserted through stoppers into graduated cylinders, or crystallizing dishes. Funnels and dishes with a diameter of 10 cm have an area of about 80 cm2.
NXY' 11--A solution having a specific gravity of 1.0255 to 1.0400 at
25C (77"F) will meet the concentration requirement. The concentration may also be determined as follows: Dilute 5 mL ofthe collected solution to 100 mL with distilled water and mix thoroughly; pipet a 10-mL aliquot into an evaporating dish or casserole; add 40 mL of distilled water and 1 mL of 1 % potassium chromate solution (chloride-free) and titrate with 0.1 N silver nitrate solution to the first appearance of a permanent red coloration. A solution that requires between 3.4 and 5.1 mL of 0.1 N silver nitrate solution will meet the concentration requirements.
9.3 The nozzle or nozzles shall be so directed or baffled that none of the spray can impinge directly on the test specimens.
10. Continuity of Test
10.1 Unless otherwise specified in the specifications cov ering the material or product being tested, the test shall be continuous for the duration ofthe entire test period. Contin uous operation implies that the chamber be closed and the spray operating continuously except for the short daily
9 It has been observed that periodic fluctuations in air pressure of 3.4 kN/m2 (0.5 psi) resulted in about a twofold increase in the corrosivity of the fog from a nozzle which was being operated at an average pressure of 110 kN/m2 (16 psi). Controlling the fluctuations within 0.7 kN/m2 (0.1 psi). however, avoided any increase in the corrosivity of the salt fog. See Darsey, V. M. and Cavanagh, W. R., "Apparatus and Factors in Salt Fog Testing," Proceedings, ASTM, Vol 48, 1948, p. 153.
interruptions necessary to inspect, rearrange, or remove test specimens, to check and replenish the solution in the reservoir, and to make necessary recordings as described in Section 9. Operations shall be so scheduled that these interruptions are held to a minimum.
11. Period of Test
11.1 The period of test shall be as designated by the specifications covering the material or product being tested or as mutually agreed upon between the purchaser and the seller.
NZ[' 12--Recommended exposure periods are to be as agreed upon
by the purchaser and seller, but exposure periods of multiples of24 h are suggested.
12. Oeaning of Tested Specimens
12.1 Unless otherwise specified in the specifications cov ering the material or product being tested, specimens shall be treated as follows at the end of the test:
12.1.1 The specimens shall be carefully removed. 12.2 Specimens may be gently washed or dipped in dean running water not warmer than 38C (100'F) to remove salt deposits from their surface, and then immediately dried. Drying shall be accomplished with a stream of dean, compressed air.
13. Evaluation of Results
13.1 A careful and immediate examination shall be made for the extent of corrosion of the dry test specimens or for other failure as required by the specifications covering the material or product being tested or by agreement between the purchaser and the seller.
14. Records and Reports
14.1 The following information shall be recorded, unless otherwise prescribed in the spedfications covering the mate rial or product being tested:
14.1.1 Type of salt and water used in preparing the salt solution,
14.1.2 All readings of temperature within the exposure zone of the chamber,
14.1.3 Daily records of data obtained from each fogcollecting device including the following:
14.1.3.1 Volume of salt solution collected in millimetres per hour per 80 cm2,
14.1.3.2 Concentration or specific gravity at 35C (95F) of solution collected, and
14.1.3.3 pH of collected solution. 14.4 Type of specimen and its dimensions, or number or description of part, 14.5 Method of cleaning spedmens before and after testing, 14.6 Method of supporting or suspending article in the salt spray chamber, 14.7 Description of protection used as required in 5.5, 14.8 Exposure period, 14.9 Interruptions in test, cause and length of time, and 14.10 Results of all inspections.
NZ[' 13--If any of the atomized salt solution which has not
contacted the test specimens is returned to the reservoir, it is advisable to record the concentration or specific gravity of this solution also.

15. Precision and Bias10
15.1 The reproducibility of results in the salt spray test is highly dependent on the type of specimens tested and the evaluation criteria selected as well as the control of the operating variables. In any testing program, sufficient repli cates should be included to establish the variability of the results. Substantial variability is often observed when similar specimens are tested in different fog chambers even, though
10 Supporting data are available on loan from ASTM Headquarters. Request RRrGOt-1003.
the testing conditions are nominally similar and within the ranges specified in this method.
15.2 The salt spray (fog) test is intended to reproduce the corrosion that occurs in atmospheres containing salt spray or splash. It has been widely observed, however, that rankings of different alloys or coating systems, or both, do not necessarily fall in the same order as atmospheric tests in marine or road salt splash environments. This test has been more useful in rating the relative resistance of a specific type of protective coating, for example, hot-dip zinc coatings on steel. Interpretation of the results of this method beyond this purpose must be verified by actual exposure tests.

XI. CONSTRUCTION OF APPARATUS
X1.1 Cabinets
XI. 1.1 Standard salt spray cabinets are available from several suppliers, but certain pertinent accessories are re quired before they will function according to this method and provide consistent control for duplication of results.
XI. 1.2 The salt spray cabinet consists of the basic chamber, an air-saturator tower, a salt solution reservoir, atomizing nozzles, specimen supports, provisions for heating the chamber, and suitable controls for maintaining the desired temperature.
XI. 1.3 Accessories such as a suitable adjustable baffle or central fog tower, automatic level control for the salt reservoir, and automatic level control for the air-saturator tower are pertinent parts of the apparatus.
XI. 1.4 The cabinet should be of sufficient size to test adequately the desired number of parts without over crowding. Small cabinets have been found difficult to control

and those of less than 0.43-m3 (15-ft3) capacity should be
avoided. X1.1.5 The chamber may be made of inert materials such
as plastic, glass, or stone, but most preferably is constructed of metal and lined with impervious plastics, rubber, or epoxy-type materials or equivalent.
XI .2 Temperature Control
XI.2.1 The maintenance of temperature within the salt chamber can be accomplished by several methods. It is generally desirable to control the temperature of the sur roundings of the salt spray chamber and to maintain it as stable as possible. This may be accomplished by placing the apparatus in a constant-temperature room, but may also be achieved by surrounding the basic chamber of a jacket containing water or air at a controlled temperature.
X 1.2.2 The use of immersion heaters in an internal salt solution reservoir or of heaters within the chamber is detrimental where heat losses are appreciable, because of solution evaporation and radiant heat on the specimens.
Xl.2.3 All piping which contacts the salt solution or spray should be of inert materials such as plastic. Vent piping should be of sufficient size so that a minimum of back pressure exists and should be installed so that no solution is trapped. The exposed end of the vent pipe should be shielded. from extreme air currents that may cause fluctuation of pressure or vacuum in the cabinet
XU Spray Nozzles
XI .3.1 Satisfactory nozzles may be made of hard rubber, plastic, or other inert materials. The most commonly used type is made of plastic. Nozzles calibrated for air consump. tion and solution-atomized are available. The operating characteristics of a typical nozzle are given in Table XI.1.
X 1.3.2 It can readily be seen that air consumption is relatively stable at the pressures normally used, but a marked reduction in solution sprayed occurs if the level' of the solution is allowed to drop appreciably during the test. Thus,

the level of the solution in the salt reservoir must be maintained automatically to ensure uniform fog delivery during the test11
X 1.3.3 If the nozzle selected does not atomize the salt solution into uniform droplets, it will be necessary to direct the spray at a baffle or wall to pick up the larger drops and prevent them from impinging on the test specimens. Pending a complete understanding of air-pressure effects, etc., it is important that the nozzle selected shall produce the desired condition when operated at the air pressure selected. Nozzles are not necessarily located at one end, but may be placed in the center and can also be directed vertically up through a suitable tower.
XI.4 Air for Atomization
X 1.4.1 The air used for atomization must be free of grease, oil, and dirt before use by passing through wellmaintained filters. Room air may be compressed, heated, humidified, and washed in a water-sealed rotary pump, if the temperature of the water is suitably controlled. Otherwise
1' A suitable device for maintaining the level of liquid in either the saturator tower or reservoir oftest solution may be designed by a local engineering group, or may be purchased from manufacturers of test cabinets as an accessory.
cleaned air may be introduced into the bottom of a tower filled with water, through a porous stone or multiple nozzles. The level of the water must be maintained automatically to ensure adequate humidification. A chamber operated ac cording to this method and Appendix will have a relative humidity between 95 and 98 %. Since salt solutions from 2 to 6 % will give the same results (though for uniformity the limits are set at 4 to 6 %), it is preferable to saturate the air at temperatures well above the chamber temperature as insur ance of a wet fog. Table X1.2 shows the temperatures, at different pressures, that are required to offset the cooling effect of expansion to atmospheric pressure.
X 1.4.2 Experience has shown that most uniform spray chamber atmospheres are obtained by increasing the atom-

XI3 Types of Construction
X 1.5.1 A modem laboratory cabinet is shown in Fig.
Xl.l. Walk-in chambers are not usually constructed with a
sloping ceiling due to their size and location. Suitably located
and directed spray nozzles avoid ceiling accumulation and
drip. Nozzles may be located at the ceiling, or 0.91 m (3 ft)
from the floor directed upward at 30 to 60' over a pas
sageway. The number of nozzles depends on type and
capacity and is related to the area of the test space. An 11- to
19-dm3 (3- to 5-gal) reservoir is required within the chamber;
with the level controlled. The major features of a walk-in
type cabinet, which differs,significantly from the laboratory
type, are illustrated in Fig; XI.2. Construction of a plastic
nozzle, such as is furnished by several suppliers, is shown in
Fig. XI.3.

X2. USE OF THE SALT SPRAY (FOG) TEST IN RESEARCH
X2.1 The detailed requirements of this method are pri marily for quality acceptance and should not be construed as([ the optimum conditions for research studies. The test has been used to a considerable extent for the purpose of comparing different materials or finishes with an acceptable standard. The recent elimination of many cabinet variablesand the improvement in controls- have made the three ASTM Salt Spray Tests: Method B 117, B 287, and B 368, into useful tools for many industrial and military production and qualification programs.
X2.2 The test has been used to a considerable extent for the purpose of comparing different materials or finishes. It should be noted that there is seldom a direct relation between salt spray (fog) resistance and resistance to corrosion in other media, because the chemistry of the reactions/ including the formation of films and their protective value, frequently varies greatly with the precise conditions encoun tered. Informed personnel are'aware of the erratic composi tion of basic alloys, the possibility of wide variations in quality and thickness of plated items produced on the same racks at the same time, and the consequent need for a mathematical determination of the number of specimens required to constitute an adequate sample for test purposes, In this connection it is well to point out that Method B M 7 is not applicable to the study or testing ofdecorative chromium
plate (nickel-chromium or copper-nickel-chromium) on steel
or on zinc-base die castings or ofcadmium plate on steel. For
this purpose Methods B 287 and B 368 are available, which are iso considered by some to be superior for comparison of
chemically-treated aluminum (chromated, phosphated, or anodized), although final conclusions regarding the validity of test results related to service experience have not been reached. Method B 117 is considered to be most useful in estimating the relative behavior ofclosely related materials in marine atmospheres, since it simulates the basic conditions with some acceleration due to either wetness or temperature
or both. X2.3- When a test is used for research, it may prove
advantageous to operate with a different solution composi tion or concentration or at a different temperature. In all cases, however, it is desirable to control,the temperature and
humidity in the manner specified, and to make certain that the composition of the settled fog and that of the solution in the reservoir are substantially the same. Where differences.develop, it is necessary to .control conditions so that .the characteristics of the settled fog meet the specified require
ments for the atmosphere.
:
X2.4 Material specifications should always be written in^
terms of the standard requirements of the appropriate salt
spray method, thereby making it possible to test a variety of
materials from different sources in the same equipment. ...

X3.1 General--This appendix covers test panels and procedures for evaluating the corrosive conditions within a salt spray cabinet The procedure involves the exposure of steel test panels and the determination of their mass losses in a specified period of time. This may be done monthly or ore frequently to insure consistent operation over time. It is also useful for correlating the corrosive conditions among different cabinets.
X3.2 Test Panels--The required test panels, 76 mm by 127 nun by 0.8 mm, are made from SAE 1010 commercial grade cold-rolled carbon steel (UNS G10080).
X3.3 Preparation ofPanels Before Testing--Clean panels before testing by degreasing only, so that the surfaces are free of dirt, oil, or other foreign matter that could influence the test results. After cleaning, weigh each panel on an analytical balance to the nearest 1.0 mg and record the mass.
X3.4 Positioning of Test Panels--Place a minimum of two weighed panels in the cabinet, with the 127-mm length supported 30 from vertical. Place the panels in the prox
imity of the condensate collectors. (See Section 6.) X3.5 Duration of Test--Expose panels to the silt fog for
48 to 168 h. X3.6 Cleaning of Test Panels After Exposure--After re
moval of the panels from the cabinet, rinse each panel immediately with running tap water to remove salt, and rinse in reagent grade water (see Specification D 1193, Type IV). Chemically clean each panel for 10 min at 20-25C in a fresh solution prepared as follows:
Mix 1000 mL of hydrochloric acid (Sp. Gr. 1.19) with 1000 mL reagent grade water (D 1193, Type IV) and add 10 grams of hexamethylene tetramine. After cleaning, rinse each panel with reagent grade water (Type IV) and dry (see 12.2).
X3.7 Determining Mass Loss--Immediately after drying, determine the mass loss by reweighing and subtracting panel mass after exposure from its original mass. The mass should not vary 20 % from test to test.
X3.7.1 Data generated in the Interlaboratory Study using this method are available from ASTM as Research Report.

acid number (coatings)--the number of milligrams of potas sium hydroxide (KOH) required to neutralize the free acids in 1 g of an oil, resin, varnish, or other substance; generally reported on the nonvolatile content.
acid value (coatings)--see add number.
acrylic resin--under resin, synthetic, see acrylic resin.
adhesion promoters--materials built into the binder or added to the paint to form primary bonds to either the substrate or the previously applied coating with the specific aim ofimproving the dry or wet adhesion, or both.
alkyd resin--under resin, synthetic, see alkyd resin.

associative thickener--water soluble polymers containing hydrophobic groups that are capable of nonspedfic hydrophobic association similar to surfactants that elevate viscosity presumably by assodation between thickener partides or thickener and dispersed particles that may be present in the aqueous system such as latex particles rather than through high molecular weight or chain stiffness of the thickener molecules themselves,
autodeposition--a single-step immersion metal finishing pro cess in which an organic coating is applied by means of unique surface chemical reactions carried out in an aqueous latex dispersion, also referred to as chemiphoresis. Components within the bath give rise to chemical reac tions that slightly solubilize the metallic surface and lead to destabilization, deposition, and coalescence of the dispersed latex particles at that surface.
`D< ( a``< bn--The deposition rate of the latex is controlled by the rate of surface solubilization. The process does not require any pretreatments such as phosphating, needs no external energy input, and gives rise to deposition wherever the solution wets the substrate. Irregularly shaped parts can be uniformily coated.

These fibrous minerals may or may not be asbestos. industrial talc, nonasbestos type--industrial talc of which less than 2 particles per 100 particles (by light microscopy) are asbestos fibers, where "asbestos fiber" is defined as being both a fiber by Definitions D 2946 and one of the asbestiform varieties of serpentine, riebeckite, cummingtonite (which are chrysotile, crocidolite and amosite, respectively), anthophyllite, tremolite, or actinolite. The nonasbestiform varieties of these same minerals are not asbestos. intumescent coating--a fire-retardant coating (which see) that when heated forms a foam produced by nonflammable gases, such as carbon dioxide and am monia. This results in a thick, highly insulating layer of carbon (about fifty times as thick as the original coating) that serves to protect the coated substrate from fire, japan--a varnish yielding a hard, glossy, dark-colored film.

exposure to humid atmosphere or chemical attack; See
white rust. rust resistance (coatings)--the ability of a coating to protect
the substrate of iron or its alloys from rusting, saturation--under color of an object, see saturation. scaling resistance (coatings)--See flaking resistance, sealer--a liquid composition to prevent excessive absorption
of finish coats into porous surfaces; also a composition to prevent bleeding (see size). semidrying oil--an oil that possesses the characteristics of a drying oil but to a lesser degree. There is no definite line of demarcation between drying and semidrying oils, shade--a term descriptive of a lightness difference between
surface colors, the other attributes of color being essen tially constant. A lighter shade of a color is one that has higher lightness but approximately the same hue and saturation; and a darker shade is one that has a lower
lightness. Primarily, the term "shade" is derived from shadow and
designates a change in appearance analogous to that produced by a local reduction in illumination. It should, therefore, when strictly used, express only the change toward a darker color. Shade of a color has been defined by several authorities as the mixture of black with that color, thus establishing its opposite character to "tint," but by extension of its relative sense it has been frequently and widely used to include lighter shades by use of the adjective "lighter" or "paler." Although such expressions apparently involve a contradiction, it is clear that while we may have a shade of a color or darker color of the same sort, it is easy to conceive of another shade not quite so dark and therefore lighter. sheepskin paint roller cover--a cover in which the paint applicating material is wool fleece still attached to its tanned natural skin. size--usually a liquid composition to prevent excessive ab sorption of all paints into plaster, old wall paint, and similar porous surfaces; also a liquid composition used as a first coat on metal to improve adhesion of succeeding coats (latter usage is limited to the metal decorating
industry). The terms sealer and size are almost synonomous, but
usage has established certain differences. A sealer is ordinarily a thin varnish or clear lacquer and is usually applied on wood and metal surfaces. Ordinary painter's size is a thin solution of glue, starch or other water-soluble substance and is usually applied on piaster surfaces, but size used in metal decorating is a thin varnish. spar varnish--under varnish, see spar varnish, spirit varnish--under varnish, see spirit varnish. soil (coatings)--disfiguring foreign materials such as dirt, soot, or stain, other than microorganisms, deposited on or embedded in a dried film of applied coating material; also called dirt. solid--(flammability regulations) a substance that has a viscosity greater than 1 x tO3 St (1 x 10-1 m2 s_1) at 104F (40C) or an equivalent viscosity at an agreed upon
temperature. (This includes powders and granular mate rials.) spreading rate--the area covered by a unit volume of coating
material frequently expressed as square feet per gallon.
stain--a discoloration, arising from foreign materials, that penetrates into the coating.
stain--a penetrating composition that changes the color of a surface, usually transparent and leaving practically no surface film.
styrene resin--under resin, synthetic, see styrene resin. surfacer--a pigmented composition for filling minor irregu
larities to obtain a smooth uniform surface preparatory to applying finish coats; usually applied over a primer and sandpapered for smoothness. synthetic paint roller cover--a cover in which the paint ap plicating material is man-made material. synthetic resin--see resin, synthetic.
talc--see industrial talc and industrial talc, nonasbestos type, temporary coating--a coating designed to protect or decorate
a substrate for a limited time that can be readily removed either by mechanical or chemical means, thinner--the portion of a paint, varnish, lacquer, or printing ink, or related product that volatilizes during the drying process. tint--a color produced by the mixture of white pigment or paint in predominating amount with a colored pigment or paint, not white. The tint of a color is, therefore, much lighter and much less saturated than the color itself, tinting strength--the power of coloring a standard paint or pigment. toner--an organic pigment that does not contain inorganic pigment or inorganic carrying base, undertone--the colouxtf a thin layer of pigment-vehicle mixture applied on a white background. urea resin--under resin, synthetic, see urea resin. urethane coatings--coatings based upon vehicles containing a minimum of 10 percent by weight (nonvolatile vehicle basis) of a polyisocyanate monomer reacted in such a manner as to yield polymers containing any ratio, propor tion or combination of urethane linkages, active isocyanate groups, or polyisocyanate monomer. The reac tion products may contain excess isocyanate groups avail able for further reaction at time of application or may contain essentially no free isocyanate as supplied.
Type I, one-package prereacted--urethane coatings characterized by the absence of any significant quantity of free isocyanate groups. They are usually the reaction product of a polyisocyanatc and a polyhydric alcohol ester of vegetable oil acids and are hardened with the aid of metallic soap driers.
Type II, one-package moisture cured--urethane coat ings characterized by the presence of free isocyanate groups and capable of conversion to useful films by the reaction ofthese isocyanate groups with ambient moisture.
Type III, one-package heat cured--urethane coatings that dry on cure by thermal release of blocking agents and regeneration of active isocyanate groups that subsequently react with substances containing active hydrogen groups.
Type IV, two-package catalyst--urethane coatings that comprise systems wherein one package contains a prepoly mer or adduct having free isocyanate groups capable of forming useful films by combining with a relatively small quantity of catalyst, accelerator, or crosslinking agent such as a monomeric polyol or polyamine contained in a
13

second package. This type has limited pot-life after the two vernonia ofl--a low-viscosity epoxidized drying oil from the
components are mixed. Type V, two-package polyol--urethane coatings that

FIG. 2 Two-millilitre Receiver Showing Alternative Connections to Glass Still
5. Solvent-Carrier Liquid 5.1 A solvent-carrier liquid appropriate to the material
being tested (see Table 1) shall be used. 5.1.1 Aromatic Solvent--The following aromatic solvents
are acceptable: 5.1.1.1 Industrial Grade Xylene. 5.1.1.2 A blend of 20 volume % industrial grade toluene
and 80 volume % industrial grade xylene (Warning--Flam mable. Vapor harmful. See Annex AI.l.)
5.1.1.3 Petroleum or Coal Tar Naphtha (Warning--Ex tremely flammable. Harmful if inhaled. Vapors may cause fire. See Annex), free of water, yielding not more than 5% distillates at 125C (257F) and not less than 20% at 160C (320F) when tested by Method D 86 and with a relative density (specific gravity) not lower than 0.8545 at 15.56/ 15.56'C (60/60'F).

solvent, 5% boiling between 90' and 100'C (194' and 212'F) and 90% distilling below 210'C (410F), shall be used.
5.1.3 Volatile Spirits Solvent--The following volatile spirits solvents are acceptable:
5.1.3.1 Petroleum Spirit, with a boiling range of 100' to 120C (212' to 248'F).
5.1.3.2 Isooctane, of 95% purity or better.
6. Apparatus
6.1 General--The apparatus comprises a glass or metal still, a heater, a reflux condenser, and a graduated glass trap. The still, trap, and condenser may be connected by any suitable method that produces a leakproof joint Preferred connections are ground joints for glass and O-rings for metal to glass. Typical assemblies are illustrated in Figs. 1,2, and 3. The stills and traps should be chosen to cover the range of materials and water contents expected.
6.2 Still--A glass or metal vessel with a short neck and suitable joint for accommodating the reflux tube of the trap shall be used. Vessels of 500, 1000, and 2000-mL nominal' capacity have proved satisfactory.
6.3 Heater--A suitable gas burner or electric heater may be used with the glass still. A gas ring burner with ports on the inside circumference shall be used with the metal stilL The gas ring burner shall be of such dimensions that it may be moved up and down the vessel when testing materials that are likely to form or solidify in the still.
6.4 Glassware--Dimensions and descriptions of typical glassware for use in this method are provided in Specification E 123 and British Standard 756. A straight water-cooled condenser with a length of 400 mL is recommended in place of the length of 300 mL specified in British Standard 756.
qrN ' 2--Instead of standardizing on a particular apparatus specifi
cation with respect to dimensions and style, a riven apparatus will be deemed satisfactory when accurate results are obtained by the standard-
addition technique described in Section 7.

sible limits given in Table 2 for the various sized graduated traps are not exceeded.
7.3 A reading outside the permissible limits suggests a malfunction resulting from vapor leaks, too rapid boiling, inaccuracies in calibration of the trap, or ingress of extra neous moisture. Eliminate these factors before repeating the standardization.
8. Sampling
8.1 Sampling is defined as all steps required to obtain an aliquot ofthe contents of any pipe, tank, or other system and to place the sample into the laboratory test container. Only representative samples obtained as specified in Practice D 4057 (API Chapter 8.1) and Method D 4177 (API Chapter
17
DUP050297200
8.2) shall be used for this test method. 8.2 The size of the test portion should be based on the
expected water content of the sample, such that the water yield does not exceed the capacity of the trap (unless a trap with a stopcock is used since excess water can be withdrawn into a graduated cylinder).
9. Procedure
9.1 Measure a suitable amount of sample to an accuracy of 1 % and transfer it to the still.
9.2 Measure ordinary liquid samples in a graduated cyl inder of an appropriate size. Rinse the material adhering to the cylinder with one 50-mL and two 25-mL portions of the solvent-carrier liquid (see Section 5 and Table 1). Drain the cylinder thoroughly after the sample transfer and each
rinsing. 9.3 Weigh solid or viscous materials directly into the still
and add 100 mL of the selected solvent-carrier liquid. In cases of material with a low-water content when large samples must be used, a solvent-carrier liquid volume in excess of 100 mL may be necessary.
9.4 Glass beads or other boiling aids may be added, if
necessary, to reduce bumping. 9.5 Assemble the components of the apparatus as illus
trated in Figs. 1, 2, and 3 choosing the trap in accordance with the expected water content of the sample and making all connections vapor and liquid tight. If a metal still with a removable cover is used, insert a gasket of heavy paper, moistened with solvent, between the still body and the cover. The condenser tube and trap must be chemically dean to assure free drainage of water into the bottom of the trap. Insert a loose cotton plug in the top of the condenser to prevent condensation of atmospheric moisture inside it. Circulate cold water through the jacket of the condenser.
9.6 Apply heat to the still, adjusting the rate of boiling so that condensed distillate discharges from the condenser at the rate of 2 to 5 drops per second. If the metal still is used, start heating with the ring burner about 76 mL (3 in.) above

the bottom of the still and gradually lower the burner as the distillation proceeds. Continue distillation until no water is visible in any part ofthe apparatus except in the trap, and the volume of water in the trap remains constant for 5 min. if there is a persistent ring of water in the condenser tube carefully increase the rate of distillation or cut off the condenser water for a few minutes.
9.7 When the evolution of water is complete, allow the trap and contents to cool to room temperature. Dislodge any drops of water adhering to the sides of the trap with a glass rod or other suitable means and transfer them to the water layer. Read the volume of the water in the trap to the nearest scale division.
10. Calculation
10.1 Calculate the water in the sample, as weight or volume percent, in accordance with the basis on which the sample was taken, as follows:
Water, % = V/W x 100
where: V = volume of water in trap and W = weight (or volume of sample). Volatile water-soluble material, if present, may be measured as water.
10.2 Report the results as the water content to the nearest 0.05% if the 2-mL receiver has been used and to the nearest 0.1% if the 10-mL or 25-mL receiver has been used with a 100-mL or 100-g sample.
11. Precision and Bias
11.1 Precision--The criteria described in Section 11.1.1 and 11.1.2 should be used to judge the acceptability of results (95% probability) when using the 10-mL or 25-mL traps. The precision when using the 2-mL trap has not been established.
11.1.1 Repeatability--The difference between successive test results, obtained by the same operator with the same apparatus under constant operating conditions on identical test material, would, in the long run, in the normal and correct operation of the test method, exceed the values in Table 3 in only one case in twenty.
11.1.2 Reproducibility--The difference between two single and independent test results obtained by different operators working in different laboratories on identical test material, would, in the long run, in the normal and correct operation of the test method, exceed the values in Table 3 in only one case in twenty.
11.2 Bias--A bias statement is under development.

3.1 Appearance ofthe liquid varnish is important both for aesthetic reasons and because it indicates whether the dried film is likely to have a satisfactory appearance. Examine the liquid varnish for foreign matter, sediment or skins in accordance with Test Method D 2090.
4. Color
4.1 Most varnishes are predominantly yellow but the color ofthe liquid varnish is only a preliminary indication of the color of the dried varnish film. The initial color may bleach or may darken depending upon the conditions of exposure. Determine approximately and quickly the liquid color of small specimens in Gardner-Holdt tubes by compar ison with the Gardner Color Standards in accordance with Test Method D 1544.
4.2 Measure the color of extremely pale varnishes by using larger specimens in 100-mL cylinders, 300 mm deep, in accordance with Test Method D 1209.

9. Flash Point 9.1 Determine the flash point of varnishes having a
DUP050297204
viscosity ofless than 9.5 cSt at 77T (25C) (45 SUS at 100'F) by Test Method D 56, and of varnishes having a viscosity of more than 9.5 cSt at 77F by Test Methods D 93. Alterna tively, use Test Methods D 3278, which gives comparable results to Test Methods D 56 and D 93, and Test Method D 1310.
Nuv' --Due to various U.S. Government and State regulations, it is
now necessary to check with appropriate departments to determine which ASTM Test Method is applicable.
10. Skinning
10.1 Varnishes, which dry by oxidation, may form a skin in a partially filled can or in a filled can that is stored for a long time. Since skins are insoluble in the varnish, they must be removed before use ifa satisfactory film is to be obtained. Use the following test to determine if a varnish has an objectionable tendency to early skin formation:
10.1.1 Container--A wide-mouth jar with a capacity of 8-fluid oz (235 mL) and dimensions of 4l/i in. (115 mm) in height and 2 in. (50 mm) in diameter.
10.1.2 Procedure--Measure a 6-fluid oz (180-mL) spec imen of the varnish into the glass container. Screw the cover on tightly, invert the jar, and leave in an inverted position, at rest, and in the dark (placing under a box or in a drawer is satisfactory). Examine the varnish for skinning at specified time intervals.
11. Acid Value
11.1 The acid value of a varnish is an indication of reactivity with basic pigments and, within any one type of composition, may indicate conformity to a standard method of preparation. It is not a general criterion of excellence in a protective coating.
11.2 Determine the acid value in accordance with Test Method D 1639.
12. Reactivity of Paint Liquids
12.1 Reactivity of a varnish with zinc oxide is a partial indication ofthe stability of the consistency ofenamels made from it and various basic pigments.
12.2 Determine the reactivity in accordance with Test Method D 479.
13. Rosin Content
13.1 Improper use of rosin and its derivatives is some times associated with inferior performance of varnishes containing them. Qualitative tests for rosin may be employed to detect the use of a significant amount in varnishes. Quantitative determination of rosin may be used to control rosin content within limits agreeable to the purchaser and the seller.
13.2 Determine the rosin content quantitatively in ac cordance with Test Method D 1469 and qualitatively with Test Method D 1542.
DRYING AND CURING PROPERTIES
14. Drying Time
14.1 Small variations in film thickness, air temperature and humidity, and exposure to light and other radiation may affect drying times by 5 %.
14.2 Determine the drying stages appropriate to the var nish under test in accordance with the applicable sections of Test Methods D 1640.
IS. Print-Free Time
15.1 Varnishes intended for floors, furniture, etc., are expected to bear heavy objects for long periods without marring of the surface or adhering to the object.
15.2 Determine the print-free time in accordance with that section of Test Methods D 1640.
DRY VARNISH PROPERTIES
16. Gloss
16.1 Because varnishes are transparent or translucent, gloss must be measured on films applied to a nonreflecting substrate. The usual material is plane, black glass as de scribed in Test Method D2805 and similar to the gloss standards used in Test Method D 523. Gloss measurements of varnishes on wood substrates are generally not valid because the reflectance of the substrate can affect the result, but comparative tests in one laboratory of different varnishes on the same substrate may be helpful.
16.2 Gloss is usually measured in accordance with Test Method D 523 using 60" geometry. For greater sensitivity in evaluating high gloss varnishes, the 20 geometry may be used or Test Method D 4039 which uses both 20 and 60` geometries.
16.3 Prepare specimens in accordance with Practice D 3964, applying the varnish to black glass panels with a film applicator that has a clearance of 3 mils (75 pm) for varnishes with a nonvolatile content of 35 % or more and 6 mils (150 pm) for those with a nonvolatile content less than 35%.
16.4 Allow the films to dry under the conditions specified in Test Methods D 1640 for at least 24 h. For a rapid control test the films may be force dried at 120F (50C) for 1 h, providing it has been established that heat acceleration does not affect the gloss of the varnish.
16.5 Measure the gloss in accordance with Test Methods D 523 or D 4039 and report.
17. Resistance of Dried Films to Water and Alkali
17.1 Performance of varnish films is indicated in part by measurement of resistances of their dried films to water, alkali, and other reagents.
17.2 Determine the resistance to water and alkali in accordance with Test Method D 1647.
18. Abrasion Resistance
18.1 The durability and general performance of varnish films on floors' is influenced by many factors such as mechanical properties, film thickness, and exposure to light cleaning materials, various types of soil, and foot or vehicular traffic, so that no one set of tests are adequate to ensure universally satisfactory service.
18.2 An indication of the resistance to abrasion in sendee may be determined by Test Methods D 658, D 968, D 4060. All these test methods are suitable for interlabora? tory use only when results are compared by of numerical values.

19. Exterior Durability
19.1 Durability of varnish films varies so widely with exposure to varying conditions of atmosphere and light or other radiation, that any one set of conditions is only a preliminary indication of general durability.
19.2 Determine the exterior durability in accordance with Test Method D 1641.
20. Color of Dried Film
20.1 The color of the dry film is usually more significant than that of the liquid varnish in establishing whether the color of a varnished object will be acceptable, This can be evaluated by determining, in accordance with Test Method D 2244, the color difference of white structural glass before and after application and drying of a varnish film.
20.2 If a varnish with a dry color known to be satisfactory is available, a standard panel can be prepared and used for visual color comparison in accordance with Practice D 1729.
21. Clear Floor Sealers
21.1 Clear floor sealers are varnishes of relatively low viscosity for application to wooden or other porous surfaces and are variously used as either the sole coating or for making the substrate more uniform for application of wax, varnish, or other coatings.
21.2 Evaluate clear floor sealers in accordance with Test Method D 1546.

Purposes2
3. Significance and Use 3.1 In production of paints, smoothness of the paint film
is of paramount importance. Agglomerates or coarse parti cles larger than 45 pm are difficult to disperse and may prevent obtaining a smooth film. These test methods are a valuable quality control test for grading raw materials.
4. Apparatus 4.1 The apparatus shall consist of a 3-in. (75-tnm) 45-pm
(No. 325) sieve conforming to Specification E It. A 3-in. 45-pm sieve for comparison purposes should be retained in the laboratory as a reference standard. Whenever a new sieve is secured, a practical test of its accuracy should be made by running on it and on the reference standard sieve a compar ison test, using a pigment that has a considerable amount of coarse particles. A reserve stock of such a pigment should be kept for this purpose.

weigh on an analytical balance, recording the weight to 1 mg. 5.2 Weigh a specimen (25 g for basitj carbonate and basic
sulfate white leads, 25 g for red lead and mercuric oxide, 2 g for black pigments of low specific gravity, 3 g for Prussian blues and graphite, and 10 g for all other pigments) of the pigment to be tested on an analytical balance to 1 mg. Wet the sieve on both sides with alcohol and transfer the specimen of pigment to the sieve and wet with alcohol.
5.3 Hold the sieve under a tap delivering about 300 to 500 mL ofthe wash liquid (water) per minute. By slightly shaking the sieve, the pigment will be rapidly carried through. A soft cameTs-hair brush may be used in aiding the operation. If the sieve is held at a slight angle so that the pigment gradually collects at one edge during the washing process, and then rotated, the pigment may be brushed out rapidly, with no risk of clogging the sieve.
5.4 After most ofthe finely divided portion of the pigment has passed through the sieve (from 2 min to 1 h, according to
the kind of pigment), place the sieve in an 8-in. (200-mm) porcelain dish containing 250 mL of the wash liquid so that the sieve is covered to a depth of about 'A in. Brush the pigment remaining on the sieve with a soft 1-in. (25-mm) camel's-hair brush at the rate of two strokes per second during two periods of 10 s each. Raise the sieve from the dish after each 10-s period to let the liquid on the sieve run through. Change the liquid in the dish after every two brushing periods. Continue this operation until the wash liquid passing over the residue and through the sieve is clear and free from solid particles. When the washing appears to be complete, collect about 200 mL of the wash liquid, after passing over the residue and through the sieve, in a clean 400-mL beaker. Stir the liquid vigorously, and set the beaker on a black surface in the case of white pigments and on a white surface in the case of colored pigments. The washing is not considered complete until such a test fails to show any particles collected about the middle of the bottom of the beaker.
Nyz' 1--Occasionally, pigments will be found that foam when water is used as the wash liquid. In such instances, during the last washing in the porcelain dish the use of a liquid that breaks down the foaming and is readily miscible with water, such as alcohol, will usually overcome this difficulty.
5.5 When the washing is complete wash the pigment particles adhering to the brush back onto the sieve and wipe off the water below the sieve. Add a few drops of alcohol and then of ether to expedite drying. Dry the sieve for 1 h at

105C, cool, and weigh as described in 5.1. Calculate the percent of coarse particles.
6. Procedure foT Metallic Aluminum and Bronze Powders
6.1 In the case of metallic aluminum and bronze powders follow the procedure described in Section 5 except use 5 g of the material as the specimen and denatured alcohol, instead of water, as the wash liquid.
7. Procedure for Carbon Black in Pellet Form
7.1 Dry, cool, and weigh the sieve as described in 5.1. 7.2 Prepare a stock solution of dispersing agent3 in water; using as high a concentration of dispersing agent as possible without losing fluidity. When solution has been obtained, filter through coarse filter paper. A quart of this solution will be sufficient for several tests. 7.3 Crush the pellets between two glass plates approxi mately 12-in. (305-mm) square, using a gentle rotating motion. If 10 g of carbon black are taken, crush about 2 g at a time. Weigh into a 600-mL beaker 10 g of the crushed particles. Add enough of the dispersing solution to make a heavy paste and mix well to incorporate thoroughly the carbon black. Dilute with water to about 300 mL; then pour into the clean 45-pm (No. 325) sieve. First pass the tap water through a 45-pm sieve. 7.4 Using a small camel's-hair brush, gently brush the mix through the sieve, running tap water slowly through at the same time. When it appears that all the dispersed black has gone through, stop the tap water and continue brushing until most of the water remaining on the sieve has gone through. Add a few millilitres of the stock solution of the dispersing agent, thoroughly mix with the brush, then turn on the tap water again and wash through as before. Repeat this opera tion until no dispersed black comes through the sieve. When about 0.5 g of sand-like material is left on the sieve, the end point is being approached. At this point, adding the dis persing solution and gently rubbing it into the residue with the finger still produces a colloidal dispersion of black which easily passes through the sieve. From this point on, before each addition of dispersing agent, work the residue into the center of the sieve with the tap water. Many washings and many additions of dispersing solution are required in order to reach the end point. Take care to make certain that all the black has been washed through the sieve. 7.5 Dry the sieve in an oven at 105C for 1 h, cool, and weigh the residue. Calculate the percent of coarse particles. If the value thus obtained is greater than that specified, proceed as follows to remove any adhered carbon that will pass through the 45-pm (No. 325) sieve; Transfer the particles on the sieve to a piece of white bond paper and gently rub the carbon onto the paper with the finger. When no further real blackening of the paper occurs, carefully transfer the residue to the balance pan, weigh, and recalculate the percent of coarse particles.
8. Procedure for Water-Soluble Pigments, Pastes in Oil, Pastes in Japan, and Mixed Paints
8.1 Dry, cool, and weigh the sieve as described in 5.1.
3 Any dispersing agent specific for carbon black may be used, such as Damn No. 1 available from R.T. Vanderbilt, 30 Winfield St., Norwalk, CT 06S55.
8.2 For water-soluble pigments use 10 l g as the specimen. For pastes in oil, pastes in Japan, and mixed paints use 25 I g as the specimen. For white leads and red lead use 50 1 g as the specimen.
8.3 Weigh the specimen to 1 mg and transfer to a 250-mL beaker. Slowly add 100 mL of kerosine to the contents of the beaker, mixing thoroughly by use of a stirring rod with flattened end. Break up all lumps but do not grind the material.
8.4 Wet the sieve on both sides with kerosine; then transfer the contents of the beaker to the sieve using a wash bottle filled with kerosine.
8.5 Remove small particles retained on the stirring rod or beaker walls with a camel's-hair brush. Rinse the brush with kerosine.
8.6 When the washing is complete, wash the pigment particles adhering to the brush back onto the sieve and wipe off kerosine below the sieve. Dry the sieve for 1 h at 105C, cool, and weigh as described in 5.1. Calculate the percent of particles.
9. Procedure for Ship-Bottom Paints Containing Resins and Alcohol
9.1 In the case of ship-bottom paints containing resins and alcohol follow the procedure described in Section 8, with specimen weight of 25 1 g, but use denatured alcohol, instead of kerosine, as the wetting medium, for mixing with paint, and as the wash liquid.
10. Procedure for Cellulose Ester Lacquers
10.1 In the case of cellulose ester lacquers follow the procedure described in Section 8, with specimen weight of 25 1 g of the material but use a mixture ofequal parts of ethyl acetate, toluene, and denatured alcohol, instead of kerosine, as the wetting medium, for mixing with the lacquer, and as the wash liquid.
11. Procedure for Latex and Emulsion Paints
11.1 Apparatus--As described b Section 4 except that sieves used shall be as follows:
11.1.1 Flat Paints, a 3-in. (75-mm) 90-pm (No. 170) sieve.
11.1.2 Gloss and Semi-Gloss Paints, a 3-in. (75-mm) 75-pm (No. 200) sieve.
11.2 Dry, cool, and weigh the sieve as described in 5.1. 11.3 Weigh 25 g of paint to 1 g into a tared 250-mL beaker. Without delay, start adding 100 mL of water to the paint in the beaker, slowly and with hand stirring sufficient to thoroughly mix the paint with the water. Wet the sieve on both sides with water and transfer the contents of the beaker gradually to the sieve, using a wash bottle containing water. Small particles retained on the stirrer or beaker walls may be removed with a camel's-hair brush. Instead of tap water, use reagent water for diluting the paint sample, in the wash bottle, and for washing the paint through the sieve. The water may be delivered from a reservoir for the last step. 11.4 Follow the procedure described in 5.3. In using the camel's-hair brush, take care not to crush agglomerates that would not be broken down in normal application of the paint. Rinse the brush into the sieve at end of use. 11.5 Finally, dry, cool, and weigh the sieve for l h, as
DUP0502 97208

5. Preparation of Sample
5.1 On receipt of a sample, make a record of the label noting espedaily the brand, the name of the manufacturer, and any statement as to the composition of the paint and the net contents. Weigh the unbroken package, open, note odor and condition of the contents, pour into a clean container, and mix thoroughly by pouring from one container to the other, finally leaving the well-mixed sample in the second container which shall be tightly closed. The well-mixed sample shall be used at once for the analysis. The original can and cover may be cleaned with a suitable solvent, wiped dry, and then weighed. This weight subtracted from the original weight will give the net weight of the contents. If desired, the specific gravity of the paint may be determined, the weight per gallon calculated, and the volume ofpaint and the capacity of the container may be measured.

16.1.7 Hydrochloric Acid (1+1)--Mix equal volumes of concentrated hydrochloric acid (HCl, sp gr 1.19) (Precau tion--See 4.2) and water.
16.1.8 Hydrogen Peroxide (H202), 3%. 16.1.9 Hydrogen Sulfide (HUS). (Precaution--See 4.6)
16.1.10 Potassium Dichromate (K2Cr207). 16.1.11 Potassium Ferrocyanide, Standard Solution-- Dissolve 22 g of pure potassium ferrocyanide (K4Fe(CN)6 3H20) in water and dilute to 1 L. To standardize, transfer about 0.2 g (accurately weighed) of pure metallic zinc or
freshly ignited pure zinc oxide to a 400-mL beaker. Dissolve in 10 mL of HCl (sp gr 1.19) and 20 ml of water. Drop in a small piece of litmus paper, add NH4OH until slightly alkaline, add HCl until just acid, and then 3 mL of HCl (sp gr 1.19), Dilute to about 250 mL with hot water and heat nearly to boiling. Run in the K4Fe(CN)6 solution slowly from a buret, while stirring constantly, until a drop tested on a white porcelain plate with a drop of the uranyl indicator shows a brown tinge after standing 1 min. A blank should be run with the same amounts of reagents and water as in the standardization. The amount of JCtFefCNJfi solution re quired for the blank should be subtracted from the amounts used in standardization and in titration of the sample. The standardization must be made under the same conditions of temperature, volume, and acidity as obtained when the
sample is titrated. 16.1.12 Potassium Iodide (KI). 16.1.13 Sulfuric Acid {sp gr 1.84)--Concentrated sulfuric
acid (H2S04). (Precaution--See 4.2) 16.1.14 Sulfuric Acid (1+19)--Carefully mix 1 volume of
concentrated H2S04 (sp gr 1.84) (Precaution--See 4.2) with 19 volumes of water.
16.2 Procedure: 16.2.1 The following qualitative analysis should be made and the quantitative scheme modified as required Add acetic acid slowly to the pigment until all carbonate is decomposed (noting whether any H2S is evolved), then add a large excess of acid ammonium acetate solution. Boil, filter, and test the filtrate for metals other than lead and zinc (especially calcium and barium). The absence of calcium in this filtrate indicates that the extending pigments contain no calcium carbonate (CaC03) or calcium sulfate (CaS04); the absence of barium indicates that the extending pigments contain no barium carbonate (BaC03).
N' 2--If the original sample contained BaC03, and lead sulfate
(PbS04), CaS04, or other soluble sulfate, the soluble barium will form with the soluble sulfate a precipitate of BaS04 which will be determined as "insoluble matter." If the sample contained strontium sulfate (SrS04) or strontium carbonate (SrC03), some SrS04 may be counted as BaS04, some strontium will count as soluble barium, and some may be counted as calcium oxide (CaO). Strontium is not separated, as it probably will not be encountered, or will be present as an impurity in the barium and calcium compounds.
16.2.2 Wash the matter insoluble in acid ammonium acetate solution with another portion of this solution, and finally with hot water. This insoluble matter shall be dried, ignited, and tested for siliceous matter, BaS04, and titanium compounds. To test for the latter, place a small amount of the insoluble matter, or of the original sample (about 0.5 g) in a 250-mL resistant glass beaker; add 20 mL of concen trated H2S04 (sp gr 1.84) and 7 to 8 g of (NH4)2S04. Mix well, and boil for a few minutes. A residue denotes the
presence of silica or siliceous matter. Cool the solution, dilute with 100 mL ofwater, heat to boiling, settle, filter, and wash with hot H2S04 (1 + 19) until free from titanium. The residue may be tested for lead, barium, and silica.
16.2.3 Add H202 to a small portion of the filtrate; a clear yellow-orange color indicates the presence of titanium. Boil another portion of the filtrate with metallic tin or zinc; a pale blue to violet coloration indicates titanium.
16.2.4 Treat another portion (about 1 g) of the pigment with 20 ml of HCl (1+1) and note whether any H2S is evolved; boil the solution for about 5 min, add about 25 ml of hot water, filter, and wash with hot water. Render a small portion of the filtrate alkaline with NH4OH, acidify with HCl, and add a little BaCl2 solution; a white precipitate (BaSO,,) indicates the presence of a soluble sulfate. To another portion of the filtrate add a little H2S04; a white precipitate indicates the presence of lead, soluble barium, or both (some CaS04 may also separate). Filter, wash to remove free acid, and treat the precipitate with a few drops of KI solution; the formation of yellow lead iodide (Pbl2) indicates the presence of lead. The white precipitate may also be treated with H2S water, the formation of black lead sulfide (PbS) indicates the presence of lead.
16.2.5 To another portion of the original filtrate (see 16.2.1) add NH4OH until alkaline, render slightly acid with acetic acid, heat to boiling, and add a little K2Cr207 solution; a yellow or orange-yellow precipitate indicates the presence of lead, soluble barium, or both. To another portion of the original filtrate add a few drops of IQFetCNjg solution; a white precipitate with a bluish tinge indicates the presence of zinc. Pass into the remaining portion of the original filtrate a current of H2S for 5 to 10 min, add an equal volume of water, and pass H2S into the solution for about 5 min. Filter and wash with H2S water. Digest the precipitate with ammonium polysulfide, filter, acidify the filtrate with HCl, and warm; the presence of antimony is indicated by the separation ofan orange-colored precipitate. The filtrate from the H2S precipitate may be tested for barium, calcium, and magnesium in the usual manner.

20. Insoluble Matter
20.1 Reagents: 20.1.1 Alcohol 20.1.2 Hydrochloric Acid (sp gr 1.19)--Concentrated hy drochloric acid (HC1). (Precaution--See 4.2) 20.1.3 Hydrochloric Acid (1+1)--Mix equal volumes of concentrated HC1 (sp gr 1.19) (Precaution--See 4.2) and water. 20.1.4 Sodium Carbonate (Na2C01), anhydrous. 20.1.3 Sodium Carbonate (10 g/L)--Mix 10 g of Ma2C03 with water and dilute to 1 L. 20.1.6 Sulfuric Acid (1+4)--Carefully mix 1 volume of concentrated sulfuric acid (H2S04, sp gr 1.84) (Precaution--
See 4.2) with 4 volumes of water. 20.2 Procedure: 20.2.1 Moisten 1 g of the pigment with a few drops of
alcohol, cover, add 40 ml of HCI (1+1) and boil gently for 5 to 10 min. Wash the cover, evaporate to dryness, and heat at about 150C for 30 min to 1 h to dehydrate the residue. Moisten the residue with 4 ml of concentrated HCI (sp gr 1.19), allow to stand a few minutes, dilute with 100 ml of hot water, boil a few minutes, filter hot through paper, and wash with hot water (until washings give no test for lead and
chlorine). 20.2.2 Ignite the paper and residue in a platinum or
porcelain crucible, cool, and weigh the total insoluble matter (Note 2). (The insoluble matter may be filtered off on a Gooch crucible, washed with hot water, dried at 105"C, cooled, and weighed; it shall then be ignited, cooled, and weighed, when it is desired to get the loss on ignition (combined water, organic matter, etc.) of the same, or if the insoluble matter is not to be further examined.) If the sample contains titanium pigment, practically all of the titanium dioxide (1102) will be found in the insoluble matter along with barium sulfate (BaS04) and siliceous matter. Should an examination of the insoluble matter be necessary, it is advisable to remove the Ti02 before proceeding further. The TiOj may be remove'1 (or determined on a separate portion) in accordance with t Methods D 1394.
20.2.3 After removing the Ti02, the residue containing siliceous matter and BaS04 may be ignited to remove the filter. To determine BaS04, mix the ignited insoluble matter with about ten times its weight of anhydrous Na2C03 (grinding the mixture in an agate mortar if necessary) and fuse in a covered platinum crucible, heating about 1 It Let cool, place the crucible and the cover in a 200-mL glazed porcelain casserole (Note 5), add about 100 mL ofwater, and heat until the mass is disintegrated. Filter on paper into a 300-mL glazed porcelain casserole (leaving the crucible and the cover in the original casserole) and wash the casserole and filter thoroughly with a hot solution ofNa2C03 (10 g/L). Place the casserole containing the crucible and cover under the funnel, pierce the filter with a glass rod, and wash the residue into the original casserole by means of a jet of hot water. Wash the paper with hot HCI (1 +1) and then with hot water. Remove the crucible and the cover. Evaporate the HCI solution to dryness, and heat at about 150C for 30 min to 1 h. Moisten the residue with about 10 mL of concen trated HCI (sp gr 1.19), dilute with 100 mL of hot water, boil a few minutes, filter hot through paper, and wash thoroughly with hot water. Dilute the filtrate to a volume of 300 mL,
bring to boiling, and add, dropwise, 5 mL of H2S04 (1+4)
Allow to stand in a warm place for 1 h or so, filter on a weighed Gooch crucible, wash with hot water, ignite, cool and weigh as BaS04. Subtract the sum of the percentage 0f
BaS04 and Ti02 from the percentage of total insoluble matter and report the result as the percentage of insoluble siliceous matter (Note 6).
N' 5--A casserole is preferable to a beaker, as silica is dissolved
from glass when in long contact with a strong sodium carbonate solution.
No t e 6--Any soluble aluminum oxide (A1203) (or iron oxide (Fe^)) and in most cases magnesium oxide (MgO), and sometimes some calcium oxide (CaO), come from the siliceous pigment used Magnesium oxide generally denotes the presence of asbestine.
20.2.4 To determine silica, acidify the filtrate from the barium carbonate (BaC03) filtration (20.2.3) with HCI, boil to expel the COz, evaporate to dryness, bake to dehydrate the silica, moisten with HCI, dilute with 100 mL of hot water, and boil and filter through the same paper as was used to recover silica from the BaC03 portion. Wash thoroughly with hot water and proceed in accordance with Test Methods D717.
20.2.5 If it is desired to look for magnesium, combine the filtrate obtained in accordance with 20.2.4 with the filtrate from the final BaS04 separation (20.2.3) and test for A1203 and MgO in the usual way. To recover MgO that may have dissolved in the procedure for the elimination of the Ti02, make the* filtrate containing the Ti02 just alkaline with NH4OH, bring to boiling, filter, and wash. The filtrate may be tested for MgO. Any A1203 present will be precipitated along with the Ti02. To recover this, ignite and weigh as Ti02 and A1203. Deduct for Ti02 present in the sample; the difference is A1203.

concentrated H2S04 (sp gr 1.84) (Precaution--See 4.2) with 1 volume of water.
21.2 Procedure: 21.2.1 Unite the filtrate and washings (total volume 150 to 200 mL) from the total insoluble matter (see Section 20), pass H2S into the solution until it is saturated, add an equal volume of water, and again saturate with H2S. Filter, wash with water containing a little H2S, dissolve in hot HN03 (1+3), washing the paper with hot water. Add 10 to 20 mL of H2S04 (1+1), evaporate until copious fumes of H2S04 are evolved. Cool, add about 75 ml of water and then about 75 mL of ethyl alcohol (95%). Stir, let settle, filter on a Gooch crucible, wash with diluted alcohol, and dry in an oven at 105 to 110'C; or, ignite gently in a radiator7 or muffle, cool, and weigh as lead sulfate (PbS04). Calculate to lead oxide (PbO).
N' 7--It is not possible to determine the amount of basic lead
carbonate and lead sulfate when carbonates or soluble sulfates of other metals, such as calcium, are present. Also, neither basic lead carbonate nor basic lead sulfate are definite compounds.
21.2.2 If the pigment contains antimony, filter and wash the sulfide precipitate as described in 21.2.1. Wash the precipitate with a fine jet of water from the paper into a porcelain dish or casserole, add 25 mL of ammonium polysulfide, cover the vessel, and warm the mixture at 40 to 60C for 10 to 15 min while stirring frequently. Wash the cover, filter through the same paper, and wash with Na2S (20 to 30 g/L) or (NH4)2S solution. Discard the filtrate. Dissolve the residue in hot HN03 (1+3), and determine the lead as lead sulfate (PbS04) as described in 20.2.1; or, the original sulfide precipitate may be discarded and the lead determined on a separate portion of the pigment as follows: to 1 g of the sample in a covered beaker, add 40 mL of HC1 (1+1) and boil gently for 5 to 10 min. Wash off the cover and evaporate to dryness. To the residue add sufficient HC1 (sp gr 1.19) to dissolve the PbS04 (with pigments containing considerable amounts of PbS04, it may be necessary to add 15 to 20 ml of HC1 (sp gr 1.19)), add about 50 mL of hot water, boil a few minutes, filter hot through paper, and wash with hot water until the washings give no test for lead. (If the sample contains no insoluble matter, omit the filtration.)
21.2.3 To the filtrate add 20 mL of H2S04 (sp gr 1.84) and evaporate until dense white fumes of sulfur trioxide (S03) are copiously evolved. Allow to cool, but not below 60C, and then add slowly 50 mL of water while agitating the solution. Heat to boiling for several minutes in order to ensure complete solution of antimony sulfate. Allow the PbS04 to settle out until the supernatant liquid is clear, not letting the temperature fall below 60C. If the liquid does not clear quickly it must be heated longer. When clear, pour the solution through a weighed porcelain Gooch crucible with asbestos mat, decanting the solution as completely as pos-1

sible without allowing more than a very small amount of PbS04 to go over into the crucible. Add 10 mL more of concentrated H2S04 (sp gr 1.84) to the PbS04 in the original beaker and boil for several minutes. Cool, add slowly 30 mL of water, and again heat to boiling for a few minutes. Allow the solution to cool to about 60"C and completely transfer the PbS04 to the Gooch crucible. Wash with "lead acid" (see 21.1.9) to remove soluble sulfates and finally wash free of acid with diluted alcohol (equal parts of ethyl alcohol or denatured alcohol and water). Dry in an oven at 105 to 1 ICC, or ignite gently in a radiator or muffle. Calculate to PbO, or determine as lead chromate (PbCr04) as described in 21.2.6.
21.2.4 If soluble compounds of barium or calcium are present, barium sulfate (BaS04) and calcium sulfate (CaS04) will be included with the PbS04. If soluble silica (Si02) is present, it will also be included with the PbS04. In such cases, the PbS04 precipitate after washing with diluted alcohol may be dissolved in acid ammonium acetate and the lead determined as PbCr04 as described in 21.2.6. For ordinary work, the amount of BaS04 dissolved by the acetate treatment may be disregarded.
21.2.5 If the pigment contains no soluble antimony, barium, or calcium compounds, the lead may be determined directly on the original pigment as follows: to 1 g of the sample in a covered beaker, add 25 mL of HN03 (1+1) and boil gently a few minutes. Wash off the cover, evaporate to dryness on a steam bath, moisten with HN03, add hot water, and heat a few minutes. Filter and wash with hot water until washings are lead-free. Add 10 to 20 ml of H2S04 (1+1) to the clear solution, evaporate, and determine lead as PbS04 as described in 21.2.1.
21.2.6 In the absence of soluble compounds of antimony, iron, aluminum, and barium, the following procedure may be used: treat 1 g of the original pigment with 25 mL of HN03 (1+1) and proceed as described in 20.2.1. To the clear solution, diluted to 200 mL, add NH4OH in slight excess, acidify with acetic acid, and add 4 to 6 mL more of acetic acid. Heat to boiling and add 10 to 15 mL of a solution of K2Cr207 (100 g/L). Heat until the yellow precipitate assumes an orange color, let settle, and filter on a weighed Gooch crucible. Wash by decantation until the washings are color less, finally transferring all of the precipitate. Wash with ethyl alcohol (95 %) and then with ether. Dry to constant weight at 110C, cool, and weigh as PbCr04. Calculate to PbO.
22. Antimony Oxide
22.1 Determine antimony oxide in accordance with Test Method D 2350.
23. Soluble Barium
23.1 Boil the combined filtrate and washings, reduced to volume by evaporation if need be, from the lead sulfate (PbS) precipitate (see 21.2) to expel hydrogen sulfide (H2S). Add a slight excess of H2S04 (1+4) over the amount required to precipitate the barium, heat to boiling, let stand on a steam bath about 1 h, filter on a weighed Gooch crucible, wash with hot water, dry, ignite, cool, and weigh as barium sulfate (BaS04) (Notes 2 and 8). Calculate to barium oxide (BaO).
N' 8--The precipitate will include any BaS04 that may have been
dissolved as such. The weighed precipitate should be tested for CaS04,

Precaution--See 4.2. 24.1.4 Methyl Red Indicator, Alcoholic Solution (2 g/ L)--Dissolve 0.2 g of methyl red in alcohol and dilute to 100 mL. 24.1.5 Nitric Add (sp gr 1.42)--Concentrated nitric acid (HN03). Precaution--See 4.4. 24.2 Procedure; 24.2.1 Boil the filtrate from the lead sulfide (FbS) precip itate (see 21.2) to expel hydrogen sulfide (H2S), add a few drops of HN03, and continue the boiling a few minutes to oxidize any iron that may be present. In case soluble barium was present, use the filtrate from 23.1. To the solution containing at least 25 g of NH4CI/L of solution, or an equivalent amount of HC1, add a few drops of methyl red indicator, alcoholic solution and heat just to boiling. Care fully add NH4OH (1+5) dropwise until the color of the solution changes to a distinct yellow. Boil the solution for I to 2 min and filter at once. Wash the precipitate thoroughly with hot NH4CI solution (Note 9). Ignite the precipitate, cool, and weigh as aluminum oxide (A1203) (Note 10).
No t e 9--For very accurate work, or when the precipitate is large, the precipitate should be dissolved in HC1 (1+1) and the precipitation repeated.
No t e 10--This precipitate may also contain ferric oxide (Fe203), titanium dioxide (Ti02), and phosphorus pentoxide (P2Os).

Let stand 8 to 14 days, siphon off the dear solution (or filter through an asbestos filter), and standardize against NIST's standard sample 40c of sodium oxalate as follows: in a 400-mL beaker, dissolve 0.25 to 0.30 g (accurately weighed) of sodium oxalate in 250 mL of hot water (80 to 90C) and add 15 mL of sulfuric acid (H2S04, 1+1). Titrate at once with the KMn04 solution, stirring the liquid vigorously and continuously. The KMn04 must not be added more rapidly than 10 to 15 mL/min, and the last 0.5 to 1 mL must be added dropwise with particular care to allow each drop to be fully decolorized before the next is introduced. The temperature of the solution should not be below 60C by the time the end point is reached. (Too rapid cooling may be prevented by allowing the beaker to stand on a small asbestos-covered hot plate during the titration. The use of a small thermometer as a stirring rod is most convenient.) The weight of sodium oxalate used multiplied by 0.833 gives its iron equivalent. The KMn04 solution should be kept in a glass-stoppered bottle painted black to keep out light. 26.1.4 Sulfuric Acid {1+4)--Carefully mix 1 volume of concentrated sulfuric acid (H2S04, sp gr 1.84) (Precaution-- See 4.2) with 4 volumes of water. 26.2 Procedure: 26.2.1 Heat to boiling the united filtrate and washings, reduced in volume if need be, from the ZnS determination (see 25.2.2), add 1 mL of NH4OH and an excess of a hot saturated (NH4)2C204 solution. Continue the boiling until the precipitate becomes granular, let stand about 1 h, filter, and wash with hot water. Ignite, cool, and weigh as calcium oxide (CaO) (Notes 2, 12, and 13). Alternatively, place the beaker in which the precipitation was made under the funnel, pierce the apex of the filter with a stirring rod, and wash the precipitate into the beaker with hot water. Pour warm H2S04 (1+4) through the paper and wash a few times. Add about 30 mL of H2S04 (1+4), dilute to about 250 mL, heat to 90'C, and titrate at once with 0.1 N KMn04 solution (the temperature of the solution should not be below 60C when the end point is reached, see 25.1.3). Calculate to CaO (Notes 2, 12, and 13). (The iron equivalent of KMn04 X 0.502 = CaO value.)
No t e 12--Care must be exercised in this washing, as 1 L of boiling water will dissolve over 0.01 g ofcalcium oxalate (CaC204).
No t e !3--For more accurate work, the CaC204 precipitate should be ignited, cooled, cautiously moistened with water, redissolved in HQ, and the solution diluted to 100 mL. Add NH,OH in slight excess, boil the liquid, and filter and wash if a precipitate appeals. Reprecipitate the calcium with NH4OH and (NH4)2C204, as described in 25.2.1, filter, wash, ignite, cool, and weigh; or, titrate as described.
27. Soluble Magnesium
27.1 Reagents: 27.1.1 Ammonium Hydroxide {sp gr 0.90)--Concentrated ammonium hydroxide (NH4OH). Precaution--See 4.1. 27.1.2 Hydrochloric Acid {sp gr 1.19)--Concentrated hy drochloric acid (HCI). Precaution--See 4.2. 27.1.3 Hydrochloric Acid {1+3)--Mix 1 volume of con centrated HQ (sp gr 1.19) (Precaution--See 4.2) with 3 volumes of water.
27.1.4 Sodium Ammonium Phosphate, Saturated Solution (NaNH4HP04).
27.2 Procedure: 27.2.1 Acidify the filtrate from the calcium determination (see 26.2.1) with HCI, add 10 mL of a saturated solution of Na(NH4)HP04 and NH4OH dropwise, with constant stir ring. When the crystalline magnesium ammonium phos phate (Mg(NH4)P04 has formed, add 5 mL excess of NH4OH. Allow the solution to stand in a cool place for not less than 4 h, preferably overnight (Note 14). Filter and wash with water containing 2.5 % ammonia. Dissolve the precipi tate in a small quantity of hot HCI (1+3), dilute the solution to about 100 mL with water, add 1 mL of a saturated solution-of Na(NH4)HP04 and NH4OH dropwise, with constant stirring, until the precipitate is again formed, and then add 5 mL excess ofNH4OH. Let the precipitate stand in a cool place for not less than 2 h, filter on a Gooch crucible, wash with water containing 2.5 % of ammonia, ignite, cool, and weigh as magnesium pyrophosphate (MgP207) (Note 15). Calculate to magnesium oxide (MgO).
No t e 14--The smaller the amount ofmagnesium present, the longer the precipitate must be allowed to settle.
No t e 15--If the sample contained manganese, it will be caught in large part with the Mg2P207. Ifdesired, manganese may be determined by dissolving the Mg2P207. If desired, manganese may be determined by dissolving the Mg2P207 in nitric acid (Precaution--See 4.4) and applying the bismuthate method.
28. Carbon Dioxide
28.1 Determine carbon dioxide in accordance with Test Methods D 1301.
29. Total Soluble Sulfur Compounds (Note 2)
29.1 Determine total soluble sulfur in accordance with Methods D 34. This determination includes soluble sulfates, sulfur trioxide (S03) formed from sulfur dioxide, (S02), and the S03 that is formed from sulfide sulfur.
30. Soluble Sulfate (Note 2)
30.1 Determine soluble sulfates in accordance with Methods D 50-.
31. Sulfide Sulfur
31.1 Determine sulfide sulfur in accordance with Test Method D 2351.

32. Sulfur Dioxide
32.1 Determine sulfur dioxide in accordance with Test Method D 2352.
33. Matter Soluble in Water
33.1 Determine matter soluble in water in accordance with Test Methods D 1208.
No t e 16--The nature of the water-soluble matter may be deter mined by further examination, as the percentages of sulfur trioxide (S03) and calcium oxide (CaO) may be indicative.
No t e 17--The water-soluble content of composite pigmentation, as determined in accordance with this method, is frequently higher than the sum ofthe water-soluble matter in the individual pigments. Possibly this is due to reaction in water between the individual pigments.
34. Calculation
34.1 The calculation of the component pigments of a mixed or combination pigment may be a somewhat difficult matter. Certain assumptions must be made, depending upon the complexity of the mixed pigment, as to the composition or formulas ofcomponent pigments and as to the manner in which the acidic and basic radicals are combined. Add any Al203(Fe203) found in the soluble portion to the siliceous matter and report the sum as "insoluble siliceous matter" unless the soluble aluminum is high; in this case, an aluminate is probably present, and the A1203 should be reported as A1203. Ifa small amount of soluble magnesium is found, it should also be added to the siliceous matter. If the soluble magnesium is high, the presence of MgC03 is indicated, and the MgO is calculated to MgC03 as described in 34.3. The insoluble siliceous matter reported should be based on the weight obtained on drying the total insoluble matter at 105*C ifthe combined water contained therein is to be considered.
34.2 Report Ti02 as Ti02, ZnS as ZnS, and BaS04 as BaS04. If CaC03, CaS04, BaC03, and MgC03 are absent, calculate C02 to basic carbonate white lead (Pb(C03)2 Pb(OH)2), and soluble S03 to PbS04. Calculate any excess of lead to PbO, add it to the PbS04, and report the sum as basic lead sulfate. Alternatively, multiply the sum of PbS04 + PbO by 0.058 to obtain the ZnO; add this result to the PbS04 + PbO and report as basic sulfate white lead. (The ZnO factor is based on the assumption that the average composition of commercial basic sulfate white lead is 78.5 % PbS04, 16.0 % PbO, and 5.5 % ZnO.) Lead oxide (PbO) should not be reported except in the presence of PbS04 unless the entire analysis is reported in the elementary or oxide form.
34.3 If the sample contains C02 but not soluble S03, calculate total lead to basic carbonate white lead (Pb(C03)2 Pb(OH)2); calculate residual C02 to CaC03, then to BaC03 and MgC03 if soluble barium and magnesium should be present in sufficient amounts to indicate the presence of these carbonates. The C02 result will be an index ofthis. A small amount ofresidual CaO is probably from the siliceous matter and should be added to the insoluble siliceous matter.
34.4 A small amount of soluble barium may be from the CaC03 used or may be due to the solubility of BaS04, if this compound is present in the original pigment This barium may be calculated to BaS04 and added to the BaS04 found in the insoluble matter.
34.5 If the sample contains soluble S03 but no C02, calculate CaO to CaS04 or CaS04 2H20; residual S03 to PbS04; add residual PbO to PbS04 and report the sum as basic lead sulfate. Alternatively, multiply PbS04 + PbO by 0.058 and add the result to the PbS04 + PbO, and report the total as basic sulfate white lead.
34.6 If the sample contains CaC03 (MgC03, BaC03) and also basic sulfate white lead, or CaS04 and basic carbonate white lead, or a mixture of these, it is not possible to determine or calculate the amount of PbC03 or PbS04 with any degree of certainty (see Notes 2 and 3). The presence of appreciable amounts of CaO and S03 in the water-soluble matter indicates the probable presence of CaS04 in the original pigment. The following arbitrary calculations may be made: calculate water-soluble S03 to CaS04 or CaS04*2H2O, subtract this S03 from total soluble S03, and calculate the remainder to PbS04; calculate residual CaO to CaC03> and then residual C02 to (PbC03)2-Pb(0H)2. If there is an excess of C02, calculate to MgC03 or BaC03, if the amounts of soluble magnesium and barium indicate the probable presence of these carbonates. Add residual PbO to PbS04 and calculate as described in 34.5 to basic sulfate white lead.
34.7 Report total antimony as Sb203. 34.8. Calculate sulfide sulfur to ZnS, subtract the zinc equivalent to the sulfur from the total zinc, then subtract the zinc required for the basic sulfate white lead, and report the remainder as ZnO. 34.9 Report directly the following: moisture and other volatile matter, loss on ignition, S02 and matter soluble in water.

Designation: D 333 - 87 (Reapproved 1991)e1
Standard Test Methods for Clear and Pigmented Lacquers1
This standard is issued under the fixed designation D 333; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year oflast revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<) indicates an editorial change since the last revision or reapprovai.
61 No t e--Keywords were added editorially in April 1991.
1. Scope
1.1 These test methods cover procedures for testing lac quers and lacquer coatings. The test methods included are listed in Table 1.
No t e 1--In accordance with Definitions D 16, a lacquer is defined as a coating composition that is based on synthetic thermoplastic film forming material dissolved in organic solvents) and that dries primarily by solvent evaporation. Typical lacquers include those based on nitrocellulose, other cellulose derivatives, vinyl resins, acrylic resins, etc.
No t e 2--Lacquers may be applied under such diverse conditions, to so many different surfaces, and their dried films may be subjected to so many kinds ofwear and exposure that it is not possible to assure desired performance from a single selection of test methods and numerical results therefrom. Those skilled in lacquer technology may find partial assurance of obtaining desired qualities in various types of lacquers through careful selection of the methods covered herein and intelligent interpretation of results therefrom.
No t e 3--It is intended ultimately to remove ail experimental proce dures from Test Methods D 333 and to establish them as a guide to the selection of test methods for lacquer and perhaps to interpretation of results therefrom. Temporarily there remain in Test Methods D 333 a few tests that are too short or otherwise presently unsuitable for establishment under separate ASTM designations.
1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility ofthe user of this standard to establish appro priate safety and health practices and determine the applica bility ofregulatory limitations prior to use.

4. General Requirements
4.1 All tests shall be made in diffused light (not in direct sunlight), and at 73.5 3.5T (23 2C) and 50 5 % relative humidity, unless otherwise specified.
5. Preparation of Sample
5.1 Many clear lacquers and all pigmented lacquers con tain suspended solids that have a tendency to settle to the bottom of the container. Stir any settled portion with a paddle or spatula and then shake vigorously for 10 min on a mechanical agitator. Since many lacquer solvents are ex tremely volatile, care should be taken during sampling and testing to avoid loss of significant amounts of volatile matter.
6. Weight Per Gallon
6.1 Determine the density as described in Test Method D 1475. This method is particularly adaptable for highviscosity fluids or where a component is too volatile for a specific gravity balance determination. If a weight per gallon cup of 83.2-mL capacity is used, calculation of weight per gallon is simplified.
7. Nonvolatile Matter
7.1 Nonvolatile matter determination is an indication of the amount of permanent film-forming material contained in a lacquer. At ambient temperatures, drying of a lacquer film may involve gradual loss of slowly volatile solvents, hence solids determinations may differ from those resulting from a nonvolatile determination accelerated by a higher temperature.
7.2 Determine the nonvolatile content of lacquers as described in Test Methods D 1644. As an additional require ment, the specimen shall be reheated and reweighed until the weight is constant to within 1 mg. Test Method A of Test Methods D 1644 is preferred since Method B is potentially dangerous when used with lacquers.
8. Homogeneity
8.1 Good quality lacquers and their ingredients should be uniformly constituted and free from particles of foreign matter.
8.2 Determine the presence or absence of foreign matter in nonpigmented liquids for use in paints and lacquers or lacquers themselves as described in Test Method D 2090.
8.3 Determine the degree of dispersion (commonly re ferred to as "fineness of grind") of pigment, semiquanlitatively, in pigmented coating systems in accordance with Test Method D 1210.
9. Color
9.1 The color of a clear lacquer is only a preliminary indication of the color of a dried film of lacquer. The initial color may bleach and another color may appear under certain conditions of exposure.
9.2 Determine the color of clear lacquers as described in Test Method D 1544. This method gives a comparison ofthe color of the sample with that of a color reference standard.
9.3 Determine the color of essentially water-white lac quers in accordance with Test Method D 1209. This method shall be used where the color-producing bodies in the lacquer have very nearly the same light-absorption characteristics as
those of the platinum-cobalt standards.
10. Viscosity
10.1 The viscosity of a lacquer is a property that can be used as a guide in determining the ease with which a given lacquer may be applied. For example, lacquers designed for spray application may be low in viscosity whereas they are high for doctor blade or roller application.
10.2 Determine the viscosity of clear and pigmented finishes designed for spray application as described in Test Method D 1200. This method is not recommended for lacquers with viscosities requiring more than 100 s efflux time.
10.3 For precise viscosity determinations in the range from 0.4 to 16 000 cSt proceed in accordance with Test Method D 445.
N' 4--Caution should be observed in that it is recognized that
changes in viscosity may occur in lacquers upon aging.
11. Flash Point
11.1 The organic solvents used in lacquers have character istic flash points. The flash point of a liquid is defined as the lowest temperature, corrected to 101.3 kPa (760 mmHg) of pressure, of the sample at which application of an ignition source causes the vapor of the sample to ignite under specified conditions of test.
11.2 Determine the flash point by Test Method D56 or Test Methods D 93 for liquid storage regulations of Occupa tional Safety and Health Administration (OSHA) of U. S. Department of Labor and for classification of hazardous liquids for shipments under the regulations of U. S. Depart ment of Transportation and bulk shipments by water.
11.2.1 Determine the flash point of lacquer or lacquer materials having a viscosity less than 9.5 cSt at 77F (25C) or 45 SUS at 100T (37.8C) (Method D 88) by Test Method D 56 and of lacquers having a viscosity of more than 9.5 cSt at 77F (25C) or 45 SUS at 100F (37.8Q by Method A of Test Methods D 93. Use Method B of Test Methods D 93 whenever there is a question that the heat transfer within a viscous lacquer is not sufficient to assure an accurate flash point. In addition, use Method B when testing pigmented lacquers or suspensions of solids and liquids which tend to skin under test conditions.
11.3 Test Methods D 3278, which give comparable results to Test Method D 56 and Test Methods D 93 while requiring a smaller specimen and less time to run, may be used as an alternative method.
12. Panel Preparation
12.1 In the evaluation ofcoated panels a uniform dry film thickness of lacquer is essential in order to eliminate any effect due to film thickness. Unless otherwise specified, the dry film thicknesses shall be as follows:
Mils Micrometres
Lacquer primer Lacquer primer surfacer
Clear lacquer Gloss pigmented lacquer Lacquer putties
0.3 to 0.6 1.0 to 2.0 l.Oto 1.2 1.0 to 1.2 4.0 to 6.0
8 to 15

D 1200. 12.3 Cold Spray--In manual application by cold spray,
keep the air pressure constant and provide the air line with a moisture trap. Adjust the flow, gun distance from test panel, and spray pattern that the deposited film is kept smooth, level, and wet. Apply the number of coats or thickness, or both, specified in the product specification.
12.4 Hot Spray--The packaged material shall be applied with hot spray equipment approved by the Underwriter's Laboratory. When dilution is necessary, the material shall be reduced with the specified thinner to the viscosity required for hot spray application. The conditions of operation with respect to temperature of the heating unit, type of spray gun, atomization pressure and pressure on feed tank type,, adjust ment of air cap and fluid tip, distance of gun from work, and rate of flow of material at the spray nozzle shail be 9s agreed upon between purchaser and seller.
12.5 Automatic Application--Four methods of applying films of uniform thickness automatically are described in Test Methods D 823. The methods are as follows:
Test Method A--Automatic Spraying Machine, Test Method B--Automatic Dip-Coater, Test Method C--Automatic Blade Film Applicator, and Test Method D--Motor-Driven Blade Film Applicator.
13. Film Thickness
13.1 Many properties of lacquer films vary with the thickness of the dry film. The measurement of dry film thickness may be accomplished with various apparatus depending upon the substrate to which the film is applied. Three nondestructive methods of thickness determination are given for films that are not easily removable from their substrate and thus do not lend themselves to simple mea surement with a constant-pressure micrometer. Two destruc tive methods are given. The methods are as follows:
13.2 Nondestructive Methods: 13.2.1 Test Method D 1186. This method is also recom mended for thin films, less than 0.5 mil (0.005 in.) (0.013 mm) in thickness. 13.2.2 Test Method D 1400, Method A. By the use of plastic shims of known thickness, the film thickness can be estimated to approximately 10 % 13.2.3 Test Methods D 1400, Method C. 13.3 Destructive Methods: 13.3.1 Test Methods D 1005. 13.3.2 Test Methods D 1400, Method B.
14. Gloss
14.1 This property relates to that aspect of the reflecting properties of a coating as determined by the brightness and configuration of reflected images.
14.2 Determine gloss of nonmetallic finishes in accord ance with Test Method D523. This method covers the measurement of the amount of light reflected specularly from a film's surface. While this property is a function of film gloss, correlation with visual observations is not always obtained.
15. Color-Pigmented Coatings
15.1 The colors of opaque objects such as painted surfaces may be specified using visual or instrumental means.
15.2 By visual means the colors of painted surfaces in terms of the Munsell Color System may be determined i accordance with Test Method D 1535. This method provides a simple alternative to the more precise and more compli cated method of color specification based on spectropho tometry.
15.3 By spectrophotometer, either visual or photoelectric types, the colors of light-reflecting coatings and spectral characteristics may be determined using Method E 308.
16. Color Difference-Pigmented Coatings
16.1 The small daylight color differences between two similarly homogeneously colored, opaque objects such as painted surfaces may be determined using visual evaluating techniques or by instrumental means.
16.2 Determine by visual evaluation color differences of opaque materials using Practice D 1729. This practice spec ifies characteristics of light sources, illuminating and viewing conditions, size of specimens, and general procedures.
16.3 Determine small daylight color differences between opaque paint specimens in accordance with Method D 2244. This test method correlates reasonably well with visuai judgments of character and perceptibility of color differences provided specimens are illuminated and viewed under con ditions substantially the same as used in the instrument For nonfluorescent opaque paint specimens or materials that do not contain metallic pigments ("bronze" powders and alu minum powders) or "pearly" pigments or other materials that produce optical phenomena that contribute to the visual effect, test in accordance with Test Method D 2244.
17. Elongation
17.1 An elongation test may be used as an indication of the flexibility of an attached organic coating. It can also show whether there is any change during aging.
17.2 Determine the elongation of attached organic coat ings when applied to flat sheet metal of uniform surface texture in accordance with Test Method D 522 or Test Method D 1737.
18. Hardness
18.1 Determine film hardness of lacquers applied to plane rigid surfaces in accordance with Test Method D 1474. In this method the resistance of a coating to penetration by an indenter is measured and converted to a hardness value.
19. Abrasion Resistance
19.1 Determine the abrasion resistance as described in either Test Method D658 or Test Method D968. Both methods cover measurement of the resistance to abrasion of coatings applied to metal panels.
20. Print Test
20.1 A print test can be used to determine two character istics of a film. If a film is thoroughly dry, the test will give a measure to the susceptibility of the film itself to press*-' marring. However, as the test is used in a product!11' situation, it can be used to determine the degree to which 8

21. Household Chemical Resistance
21.1 Household chemicals may alter the surface of or ganic coatings, for example through discoloration, change in gloss, blistering, swelling, and loss of adhesion.
21.2 Determine, qualitatively, the effects of household chemicals in accordance with Test Method D 1308.
22. Outdoor Exposure
22.1 It is important to determine the resistance to outdoor exposure of lacquers destined for exterior use prior to their application to surfaces which may be difficult or costly to refinish, or both. Systems of primer and lacquer should be tested as a whole rather than as separate components. Experience indicates that the type of substrate employed has a marked bearing on weathering results. It is the purpose of several ASTM methods to minimize the influence of sub strate variation by providing uniform panel selection and uniform procedures for conducting exposure tests and for evaluating and recording results.
22.2 Preparation of Panels--Depending on the substrate anticipated to be coated, panels for outdoor exposure testing should be prepared and tested in accordance with the following methods:
22.2.1 Test Method D 1733. 22.2.2 Methods D 609. 22.2.3 Method D 1014. 22.3 Test Procedures--Many properties of organic coat ings should be evaluated periodically throughout the outdoor exposure period. These properties may be evaluated as follows: 22.3.1 Blistering--Test Method D 714. 22.3.2 Chalking--Method D 659. 22.3.3 Checking--Test Method D 660. 22.3.4 Cracking--Test Method D 661. 22.3.5 Rusting--Method D 610. 22.3.6 Erosion--Test Method D 662. 22.3.7 Flaking--Test Method D 772.
23. Temperature-Change Resistance
23.1 A test for resistance to temperature change, or a cold cracking test (as it is sometimes called), is designed to give an indication of the resistance of a coating system to fracturing or checking, caused both by changes in temperature and humidity and by age. The degree of correlation between test results and long-term room temperature aging varies with the type of lacquer. The industry uses the test widely and feels that systems showing good cold crack resistance usually will give satisfactory performance in service. Some factors that can affect results are the type of substrate, its thickness, the rate at which the individual panels are cooled, the film thickness, and the nature of any priming or sealer coats.
23.2 Determine the temperature-change resistance in ac cordance with Test Method D 1211, This method specifies that the test panels be aged ID days. If the panels are much ider than this, the resistance to checking is expected to be
less and sometimes considerably so depending on the nature of the film.
24. Salt Fog
24.1 Salt spray (fog) testing of lacquers applied to metal substrates is helpful in determining their resistance to failure in service under atmospheric conditions that might prevail in sea coast areas.
24.2 Under accelerated conditions of laboratory testing, only the temperature, the pH, or concentration of the salt solution, and other physical properties can be controlled, the selection of the substrate, the coating technique, the manner in which the coating is scribed (parallel or X's), the location or position of the panels within the cabinet, the length of the test, the inspection of the panels, and the method of reporting results must generally be as agreed upon between purchaser and seller. Systems of primer and lacquer should be tested as a whole rather than as separate components.
24.3 Determine the salt spray resistance as described in Method B 117.
25. Water Fog Testing
25.1 Water fog testing of lacquers is helpful in deter mining their resistance to failure in service under conditions of high humidity. Failure is usually evidenced by blushing, dulling, blistering, or excessive softening that does not disappear upon evaporation of the absorbed water. Systems of primer and top-coat lacquer should be tested as a whole rather than as separate components. The use of unrealisti cally short drying times or excessively low temperature bakes will give erratic and misleading results.
25.2 Determine resistance to failure under conditions of high humidity in accordance with Test Method D 1735.
26. Water Immersion Testing
26.1 Water immersion testing is best suited for testing lacquers or systems that will actually be soaked in water during service. Materials that will be subjected to humid atmospheres only should be subjected to water fog testing. Failure is usually evidenced by blushing, dulling, blistering, or excessive softening that does not disappear upon evapora tion of the absorbed water.
26.2 Determine, in an accelerated manner, the resistance to failure of a coating immersed in water in accordance with Practice D 870.
27. Hiding Power
27.1 Hiding power of chromatic and non-chromatic coat ings can be determined using Test Method D2805.
28. Perspiration Resistance
28.1 The effects of human perspiration on the surface of organic coatings are varied. The coating may undergo an objectionable alteration in surface appearance such as discol oration, loss of gloss, blistering, wrinkling, or roughening. The coating may lose adhesion, soften, become embrittled, or any combination of these changes may take place.
28.2 Determine the effects of perspiration on organic coatings in accordance with Test Method D2204. This method covers an accelerated procedure for determining the resistance to failure of organic coatings on metallic panels

#hen exposed to human perspiration.
29, Plasticizer Migration 29.1 Plasticizers used in vinyl fabrics may migrate into
lacquer Sims that come in contact with the fabric and cause objectionable marring and softening of the lacquer film.
29.2 Determine the tendency for plasticizer to migrate in accordance with Test Method D 2199.
30. Chip Resistance 30.1 Chip resistance testing is useful for determining the
ability ofthe coating or coating system, or both, to withstand
flying stones or other objects. Systems of primer and topcoat should be tested as a system rather than as separate compo nents.
31. Light Stability of Clear Coatings 31.1 The ability of clear coatings not to change color upon
exposure to sunlight is an important characteristic, especially over white or light-colored substrates. Coatings for indoor use may be tested in accordance with Test Method D 2620.
32. Keywords 32.1 clear lacquers; pigmented lacquers

a comparison paint at equal hiding.
4. Summary of Test Method
4.1 Qualitative--The test and comparison paints are brushed out uniformly at the same spreading rate on black and white hiding power charts. After drying the brushouts are compared visually to see which paint has been most effective in reducing the substrate contrast.
4.2 Quantitative--Additional brushouts are made with the comparison paint, if and as necessary, to determine the spreading rate at which it matches the hiding ofthe test paint brushout.
5. Significance and Use
5.1 This test method evaluates the hiding power of a test paint relative to a comparison paint. The results have significance only within that relationship. It may be used for production control or quality comparisons.
5.2 When a paint is applied by brush or any other practical method, the opacity of the film is affected by variations in film thickness related to the application proce dure and to the application characteristics of the paint. Two paints that hide equally well by this method might therefore differ considerably when applied with a doctor blade, since the latter method gives essentially perfect leveling. Different brushes or surface application conditions can likewise give different results.
No t e 1--Test Method D 2805 describes an instrumental method for quantitatively determining hiding power without reference to a material paint standard. The paint film is applied at a uniform thickness (for example, with a doctor blade), the film thickness is measured rigorously, and the opacity is evaluated photometrically. Hiding power is thereby determined with a high degree of precision.
5.3 Test Method D 344 is less precise than Test Method D 2805, but is more practical because it is responsive to the application characteristics ofpaints and is simpler in concept and execution.

6.4 Container, */2-pint can or 250-mL beaker. 6.5 Test Surface, a smooth-surfaced paper chart having adjacent black and white areas and coated with a suitable varnish or lacquer so as to render the surface impervious to paint liquids. The black and white areas of the chart shall have luminous reflectance factors of 1 % maximum and 75 % minimum, respectively, when tested in accordance with Test Method E 97. The white areas of the charts used in any one testing program shall not differ in their reflectance factors by more than 1 %. Any suitable regular design of contrasting areas may be used. The chart8 shall have a defined test area of 0.1 m2. Larger test areas may be used if available, with appropriate modification of the indicated
calculations. 6.6 Illumination, a light source providing diffuse light of
reasonable intensity, preferably northern sky light or an approximation of same. (See Practice D 1729).
7. Preparation of Brushouts
7.1 Select a convenient and suitable spreading rate, mutu ally agreeable to all parties involved in the testing program, and preferably in the range from 400 to 800 ft2/gal (9.8 to 19.6 m2/L). In any case, the spreading rate shall not be so low that the substrate contrast is difficult to see nor so high that it is difficult to apply the paint at a reasonably uniform film thickness.
No t e 2--The gallon unit referred to here and throughout this test method is the U.S. gallon (3785.4 mL).
7.2 Determine the density D in grams per millilitre of the comparisons and test paints, in accordance with Test Method D 1475.
7.3 Calculate to three significant figures the volume V in millilitres to apply for the selected spreading rate SR as follows:
Vi n_ 100
4074.6
( ' SR{m2/L) R(ft2/gal)
7.4 Calculate to three significant figures, the weight W in grams corresponding to the volume K(mL) as follows:
W(g) = P(mL) x >(g/mL)
7.5 To prepare a brushout, first stir the paint well. Then precondition the brush by dipping it into the paint and working it out on a smooth, nonporous surface. Take up the desired volume of paint in the syringe and weigh it with the brush in the empty container. Place the test chart on a level bench top, distribute the paint from the syringe all around onto the test area of the chart, then brush the paint out uniformly within the test area. Set the brushout aside to dry in a horizontal position, protected adequately from dust and under normal room conditions of ventilation and tempera ture. Reweigh the empty syringe with the brush and con tainer. The loss of weight represents the actual weight of paint applied to the test surface as opposed to the intended weight calculated from 7.3 and 7.4. If there is a discrepancy do not attempt to correct it by removing or applying paint6
6 Suitable charts are available from Lenela Company, P. O. Bos 86, HoHo-Kus, NJ 07423.
since this would disturb the leveling of the brushout. Instead, calculate the actual spreading rate as follows:
SRa ~ ^ * SRB
where: SRa = actual spreading rate, B -- intended weight, A -- actual weight, and SRb -- intended spreading rate.
8. Evaluation Procedure
8.1 Viewing conditions--When the test and comparison paint brushouts are thoroughly dry, place them vertically side by side against a flat surface and view them from a distance of 5 to 10 ft (1.5 to 3 m) under illumination conditions as described in 6.6.
8.2 Qualitative Evaluation: 8.2.1 If the contrast between the black and white areas of the test paint brushout is adjudged less than, equal to, or more than that of the comparison paint brushout, then the hiding power of the test paint is considered as better than, equal to, or poorer than that of the comparison paint. 8.2.2 If the actual spreading rate of the lower contrast paint-out is lower than that of the other paint-out by more than 3 %, prepare a second brushout with either paint so as to eliminate the difference, then compare again to confirm or revise the previous estimation of relative hiding power. 8.3 Quantitative Evaluation: 8.3.1 If the hiding of the test paint brushout does not match that of the comparison paint at the same spreading rate, make a series of additional comparison paint brushouts at several other spreading rates, differing in steps of approx imately 15 % and providing contrasts above and below that of the test paint brushout. Refer to these and to the original comparison paint brushout as standards. If the standards are prepared correctly each increase in spreading rate will correspond to a perceptible increase in contrast. Compare the standards under the viewing conditions described in 8.1 to assure that this is the case. 8.3.2 Compare the brushout of the test paint with the standards under the specified viewing conditions to deter mine which standard it matches in contrast or, if none, to which pair of successive standards it is intermediate. In the latter case view the test paint brushout with the two standards on either side and rate the contrast ofthe test paint brushout by estimating the contrast difference between it and the lower spreading rate (lower contrast) standard, as a fraction of the contrast difference between the two standards to the nearest fourth. Keeping the test paint brushout in the middle, reverse the position of the two standards and rate the test paint brushout again in the same way. The final rating is the mean of the two to the nearest eighth. 8.3.3 Calculate the spreading rate (SRC) of the compar ison paint at which it is estimated to match the hiding of the test paint brushout as follows:
SRc=SR, + X(SR2 - SRJ
where: SR i = spreading rate of the lower spreading rate (lower
contrast) standard.

where: HPt - relative hiding power of the test paint, SRt = spreading rate of the test paint, and SRC spreading rate of the comparison paint at equal
hiding, as determined by an actual match with one of the standards or by estimation between two standards as described in 8.3.2.
9. Report
9.1 Qualitative (see 8.2)--Report the relative hiding power of the test paint as better than, equal to, or poorer than the comparison paint. The report may be amplified by such terms as exactly, slightly, moderately, considerably, etc., as may seem appropriate.
9.2 Quantitative (see 8.3)--Report the relative hiding power of the test coating to the nearest whole number. This is a purely numerical value. Physical units such as square feet per gallon or square metres per litre are not applicable.
10. Precision 10.1 Qualitative--Four test paints were rated versus a
comparison paint by three laboratories, twice each by one laboratory and once each by the other two, for a total of 16 trials. There was only one discrepancy, which occurred with a paint that was apparently very similar in hiding power to the comparison paint. These results indicate that the method is effective, but more results would be required to develop an appropriate precision statement. Table 1 gives the results of these tests.

method four coatings were evaluated for hiding power against a fifth coating taken as the standard. In one labora tory each material was tested twice, but only once in the other two laboratories. Statistical analysis of the results revealed that the two results for each coating from the one laboratory were as variable as those from the other two. Consequently, the two results were treated as being indi vidual results and the between-laboratory standard deviation was found to be 10 % with 12 df. Based on this standard deviation, the following criterion should be used forjudging the acceptability of results at the 95 % confidence level:
10.2.1 Reproducibility--Two single results obtained by operators in different laboratories should be considered suspect if they differ in relative hiding power by more than 32 %.
10.2.2 Repeatability--A reasonable estimate of withinlaboratory precision could not be obtained because only one laboratory repeated the test. However, the repeatability should be similar to the reproducibility.

Designation: D 358 - 83 {Reapproved 1988)
Standard Specification for Wood to Be Used as Panels in Weathering Tests of Coatings1
This standard is issued under the fixed designation D 358; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (0 indicates an editorial change since the last revision or reapprovai.
This standard has been approvedfor use by agencies ofthe Department 0/Defense to replace Method 2031 ofFederal Test Standard No. 141. Consult the DoD Index of Specifications and Standards for the specific year of issue which has been adopted by the Department ofDefense.
1. Scope 1.1 This specification designates woods for weathering
tests of exterior solvent-borne or water-borne paints and other materials of similar purpose. Such tests may include either outdoor exposure tests or accelerated laboratory tests. It is the purpose of this specification to minimize the influence of variation of wood of a given species on test results.
2. General Considerations 2.1 A variety ofdifferent species should be used for testing
finishes because of the wide variations in the anatomy and the density between wood species. The factors have tremen dous influences on finish performance. Latewood band width and density are especially important to finish perform ance, and these parameters vary significantly between wood species. Cedar and redwood have relatively low proportions of hard summerwood distributed in narrow bands and contain extractives that discolor some paint films. Southern pine has a large proportion of hard summerwood in wide bands.
2.2 The angle between the growth rings and the surface of the specimen is very critical to finish performance. Commer cial practice utilizes the following classification system. Boards in which growth form an angle of less than 30" with the wide surface of the piece are said to be flat-sawn or flat-grained; those with the rings intersecting at angles between 30and 60are termed bastard-sawn; and those with angles greater than 60 are termed quarter-sawn, edge grain, or vertical grain.
WESTERN RED CEDAR
3. Species
3.1 The material for test panels shall be western red cedar (Thuja plicata).

3. Summary of Test Methods
3.1 The coating materials under test are applied at uni form thickness to panels of sheet metal or rubber-type materials. After drying or curing the coated panels are bent over a mandrel and the resistance to cracking of the coating is determined. In Test Method A the coated panels are bent over a conical mandrel. In Test Method B the coated panels are bent over cylindrical mandrels of various diameters.
4. Significance and Use
4.1 Coatings attached to substrates are elongated when the substrates are bent during the manufacture of articles or when the articles are abused in service. These test methods
These test methods are under the jurisdiction of ASTM Committee D-l on Is' and Related Coatings and Materials and is the direct responsibility of "rcommittee DO 1.23 on Physical Properties of Applied Paint Films.

have been useful in rating attached coatings for their ability to resist cracking when elongated. They have been useful in evaluating the flexibility of coatings on flexible substrates.
5. Test Specimens
5.1 Substrates: 5.1.1 If the purpose of the test is to determine the percent of elongation of the coating material, the substrate shall be cold-rolled steel strip V32 in. (0.8 mm) (22 gage) thick. 5.1.2 If the purpose of the test is to rate the coated material for resistance to cracking, the substrate may be any type of sheet metal or rubber-type material (for example, steel, aluminum, tinplate, or synthetic rubber). The thickness of the sheet metal may be less than V32 in. (0.8 mm) and the thickness of the rubber-type materials may be as great as V2 in. (13 mm). 5.1.3 The recommended panel size is 4 in. (100 mm) in width and 6 in. (150 mm) in length. The maximum size that the conical mandrel can accommodate is 4Vi in, (115 mm) wide and 7 Vi in. (190 mm) long. 5.1.4 The. surface preparation of the substrate shall be agreed upon between the purchaser and the seller. Prior to the application of the coating, round slightly the edges of metal panels to remove burrs in order to eliminate anoma lous edge effects.
No t e 1--If elongations are to be determined for coatings applied to substrates other than V32 in. (0.8 mm) thick cold-rolled steel, they must be measured with a special mandrel jig as described in Appendix Xl.2 and shown in Fig. X1.1. The procedure for using the jig is described in Appendix XI.3.
5.2 Coated Panels: 5.2.1 Apply uniform coatings of the materials under test to the substrates in accordance with Test Methods D 823 and air dry or bake under conditions mutually agreeable to the purchaser and the seller. If percent elongation is to be measured, a minimum thickness of 1.0 mil is required on V32 in. (0.8 mm) thick cold-rolled steel. Perform a minimum of three determinations of coating thickness on each of the specimens in accordance with Test Methods D1005, D 1186, or D 1400.
6. Conditioning and Number of Tests
6.1 Condition the test specimens for at least 24 h at 73.5 3.5F (23 2C) and 50 5 % relative humidity, and test in the same environment or immediately on removal therefrom

unless otherwise specified by the purchaser and seller. 6.2 Test at least three replicate specimens in Test Method
A and at least two replicate specimens in Test Method B at each mandrel diameter of interest.
TEST METHOD A--CONICAL MANDREL TEST
7. Apparatus
7.1 Conical Mandrel Tester, consisting of a metal cone, a rotating panel-bending arm. and panel clamps, all mounted on a metal base as illustrated in Fig. I.
7.1.1 Cone, smooth steel, 8 in. (203 mm) in length, with a diameter of Vs in. (3 mm) at one end and a diameter of 1V2 in. (38 mm) at the other end.
8. Procedure
8.1 With the operating lever of the apparatus in a hori zontal position, slip the test specimen between the mandrel and the drawbar with the finish side towards the drawbar. Rigidly clamp the specimen in a vertical position adjacent to the mandrel by placing the long edge behind the clamping bar in such a manner that the panel is always set up to the narrow end of the mandrel. Slip two sheets of No. 1 brown kraft wrapping paper, substrate 30, thoroughly lubricated on each side with talc, between the specimen and the drawbar and hold in position only by the pressure of the drawbar against the paper.
8.2 Move the lever through about 180 at uniform ve locity to bend the specimen approximately 135, If the purpose ofthe test is to measure percent elongation, the bend time should be about 15 s. To determine crack resistance under more simulated use conditions, the bend time should be some value between 1.5 s and 5 s to be agreed upon between the purchaser and the seller.
8.3 Examine the bent surface of the specimen immedi ately with the unaided eye for cracking. Having determined and suitably marked the end of the crack farthest from the small end of the mandrel, which shall be considered as the end point, bring the drawbar to the starting position and remove the panel from the mandrel. Measure the distance from the farthest end of the crack to the small end of the mandrel. This distance is used to compute the elongation.
The mandrel diameter at which cracking ceased is taken as the resistance to cracking value.
N' 2--In some cases, the measured distance is used as a measure
of crack resistance.
9. Calculation
9.1 Determine the elongation of the finish from the
plotted curve in Fig. 2. This curve represents the relationship between the percent elongation and the diameter of the
conical mandrel for a 1.0 mil coating thickness. The relation between the distance along the conical mandrel and the corresponding diameter has also been plotted on this curve
9.2 Adjust the percent elongation value obtained from Fig. 2 for coating thickness by adding the correction obtained from Fig. 3.
i ^ I
; |
No t e 3--Example--Suppose a visual examination of the finish on the bent cold-relied steel specimens Vn in. (0.8 mm) in thickness shows that the end of the first crack in the coating is at a distance of 3 in. (75 mm) from the small end of the cone. From Fig. 2 determine the percem elongation of the film from the measured crack distance, in this example 5.2 %. To correct for coating thickness add the value obtained in Fig. 3 At a crack distance of 3 in. the correction per mil (25 pm) of coating thickness is 0.3 %. If the film thickness in the example is 2 mils (50 pad the actual percem elongation is 5.2 + (2 x 0.3) = 5.8 %.

TEST METHOD B--CYLINDRICAL MANDREL TEST
12. Apparatus
12.1 Elongation Test Equipment, consisting of rods or surfaces, including cylindrical steel diameters of 1 in. (25 mm), % in. (19 mm), Vi in. (12.7 mm), 3/s in. (9.5 mm), 'A in. (6.4 mm), and Vs in. (3.2 mm), mounted on a metal base. An example of an acceptable form of this device is illustrated in Fig. 4.
13. Procedure 13.1 Place the test panel over a mandrel with the
uncoated side in contact and with at least 2 in. (50 mm) overhang on either side. Using a steady pressure of the fingers, bend the panel approximately 180 around the mandrel at a uniform velocity in a time of 1.5 to 5 s, the time being that agreed upon between the purchaser and the seller. Remove and examine the panel immediately for cracking visible to the unaided eye. If cracking has not occurred, repeat the procedure using successively smaller diameter
mandrels on previously untested areas of a specimen until failure occurs or until the smallest diameter mandrel has been used. '
13.1.1 This procedure can be applied as a "pass/fail" test by determining whether cracking is produced by a specified mandrel size.
13.1.2 The resistance to cracking value for a coating is taken as the mandrel diameter at which cracking ceases.
14. Calculation
14.1 Determine the elongation range of the material from Table 1 in which the elongation of a I mil (25 pm) thick coating on 1/32 in. (0.8 mm) cold-rolled steel is given for each mandrel diameter.
14.2 If the coating thickness exceeds 1 mil (25 pm), correct the determined elongation for film thickness using the factors for each mandrel diameter given in Table 2. Calculate the total elongation of the coating as follows:
E -- e, + ic,
where: E -- total elongation, %, Ci = elongation from Table 1, %, t = thickness, mils, and Ci = correction factor from Table 2.

APPENDIX (Nonmandatory Information)
I
XI. RELATIONSHIP BETWEEN ELONGATION AND MANDREL SIZE
Xl.l In the mandrel test, the specimens are elongated
considerably past their elastic limit. Therefore, the elonga tions obtained are considerably higher than elongation values calculated from a theoretical equation that is based on the assumption that the elastic limits of the specimens are
not exceeded. X1.2 The elongation values corresponding to mandrel
diameters in Figs. 2 and 3 of these test methods were obtained by direct measurements with a special mandrel jig.
X1.3 This jig shown in Fig. Xl.l consists of two forks for holding the mandrel and specimen in position and a roller with which the specimen is tightly wrapped around and held
against the mandrel. X1.4 Measuring Elongation With Jig--Make two parallel
gage scratches with a sharp stylus on the edge of the specimen so located that when it is wrapped around the
mandrel the included angle between the scratches will be approximately 180. In locating the scratches, it is necessary to make sure that they will be within the section of the specimen that, after bending, is tightly wrapped against the mandrel. Having located the scratches, measure the linear distance between them to within 2 pm. Clamp the specimen in the jig and bring the roller down tight against it. Draw the roller around causing the specimen to be tightly wrapped and secured against the surface of the mandrel. In order to hold the jig in this position hold the forks together with a C-clamp. Then rigidly mount the clamped jig on the table of the measuring machine.3 Each of the gage scratches shall hemade to coincide with the vertical cross-hair of the mea suring eyeuiece while the horizontal cross-hair is tangent to the curvature of the upper surface of the specimen. Take the angle read! o r at each of these points. The difference between the two angie readings is a measure of the included angle formed by the two gage scratches, and the radii drawn coincident with the scratches. Read the angle readings in minutes and seconds to a precision of5 s. Also determine the total diameter of the mandrel and the bent specimen. From these data calculate the percent elongation E at the surface of
the specimen as follows:
L - a7r/180r =[(.- d)/d] x 100
where: = angle,
= arc = rad hr
thief: = orb'd
f urvature for system (mandrel radius + + coating thickness), and 'stance between scratches.

(8,9). The geometry of angles and apertures is chosen so that these procedures may be used as follows:
4.1.1 The 60 geometry is used for intercomparing most specimens and for determining when the 20 geometry may be more applicable.
4.1.2 The 20 geometry is advantageous for comparing specimens having 60 gloss values higher than 70.
4.1.3 The 85 geometry is used for comparing specimens for sheen or near-grazing shininess. It is most frequently applied when specimens have 60gloss values lower than 10,
5. Significance and Use
5.1 Gloss is associated with the capacity of a surface to
reflect more light in some directions than in others. The
directions associated with mirror (or specular) reflection
normally have the highest reflectances. Measurements by
this test method correlate with visual observations of surface
shininess made at roughly the corresponding angles.
5.1.1 Measured gloss ratings by this test method arc
obtained by comparing the specular reflectance from the
specimen to that from a black glass standard. Since specular
reflectance depends also on the surface refractive index ofthe
specimen, the measured gloss ratings change as the surface
refractive index changes. In obtaining the visual gloss ratings,
however, it is customary to compare the specular reflectances
of two specimens having similar surface refractive indices.
Since the instrumental ratings are affected more than the
visual ratings by changes in surface refractive index, non
agreement bet--.vp.en visual and instrumental gloss ratings can
occur when mb: gloss specimen surfaces differing in refrac
tive index me compared.

6.1 Instrumental Components--The apparatus shall con sist of an incandescent light source furnishing an incident
means for locating the surface of the specimen, and a receptor located to receive the required pyramid of rays reflected by the specimen. The receptor shall be a photosen sitive device responding to visible radiation.
6.2 Geometric Conditions--The axis of the incident beam shall be at one of the specified angles from the perpendicular to the specimen surface. The axis of the receptor shall be at the mirror reflection of the axis of the incident beam. The axis of the incident beam and the axis ofthe receptor shall be within 0.1* of the nominal value indicated by the geometry. With a flat piece ofpolished black glass or other front-surface mirror in the specimen position, an image ofthe source shall be formed at the center of the receptor field stop (receptor window). The length of the illuminated area of the specimen
shall be not more than one third of the distance from the center of this area to the receptor field stop. The dimensions and tolerance ofthe source and receptor shall be as indicated in Table 1. The angular dimensions of the receptor field stop are measured from the receptor lens in a collimatedbeam-type instrument, as illustrated in Fig. 1, and from the

trated in Fig. 2. See Figs. 1 and 2 for a generalized illustration
of the dimensions. The tolerances are chosen so that errors in the son rce and receptor apertures do not produce an error of more ilia a one gloss unit at any point on the scale (5).
6.2.1 The important geometric dimensions of any specular-gloss measurement are:
6.2.1.1 Beam axis angle(s), usually 60, 20, or 85. 6.2.1.2 Accepted angular divergences from principal rays (degree of spreading or diffusion of the reflected beam).

with index is different for each geometry. Each 0.001 increment in refractive index produces a change of 0.27, 0.16, and 0.016 in the gloss value assigned to a polished standard for the 20,60, and 85geometries, respectively. For example, glass of index 1.527 would be assigned values of 89.2, 93.6, and 99.4, in order of increasing geometry.
N' 3--Polished black glass has been reported to change in
refractive index with time largely due to chemical contamination (10). The original values can be restored by optical polishing with cerium oxide. A wedge of high-purity quartz provides a more stable reference standard than glass.
7.2 Working Standards1--Ceramic tile, depolished ground opaque glass, emery paper, and other semigloss materials having hard and uniform surfaces are suitable when calibrated against a primary standard on a glossmeter known to meet the requirements of this test method. Such standards should be checked periodically for constancy by comparing with primary standards.
7.3 Store standards in a closed container when not in use. Keep them clean and away from any dirt that might scratch or mar their surfaces. Never place standards face down on a surface that may be dirty or abrasive. Always hold standards at the side edges to avoid getting oil from the skin on the standard surface. Clean the standards in warm water and a mild detergent solution brushing gently with a soft nylon brush. (Do not use soap solutions to clean standards, because they can leave a film.) Rinse standards in hot running water (temperature near 150F (65C)) to remove detergent solu tion, followed by a final rinse in distilled water. Do not wipe standards. The polished black glass high-gloss standard may be dabbed gently with a lint-free paper towel or other lint-free absorbent material. Place the rinsed standards in a warm oven to dry.
8. Preparation and Selection of Test Specimens
8.1 This test method does not cover preparation tech niques. Whenever a test for gloss requires the preparation of test specimens, use the procedures given in Test Methods D823.

Subtract it from the glossmeter reading. To measure the
correction, illuminate the specimen perpendicularly and view at the incident angle with the receiver aperture specified in 6.2 for the corresponding geometry. To compute the correction, multiply the 45, 0 directional reflectance of the specimen, determined in accordance with Test Method E 97, by the effective fraction of the luminous flux reflected by the perfect diffuse reflector and accepted by the receiver aper ture. The luminous flux entering the receiver aperture from the perfect white diffusor would give the following gloss indications for each of the geometries:

(fig. 3) on the stroboscopic timer, that is, where the lines appear to be stationary.
10.4.1 Lines moving in the direction of paddle rotation indicate a speed greater than 200 r/min and therefore, weight should be removed from the hanger. Conversely, lines moving opposite to direction of paddle rotation indicate a speed less than 200 r/min and weight should be added.
No t e 3--There are other patterns that appear at speeds other than 200 r/min (See Fig. 4). The pattern for 200 r/min should be determined before running any tests.
10.5 Repeat the determination in 10.4 until a consistent value of load is obtained (that is, to within 5 g).
11. Calculation 11.1 Procedure A: 11.1.1 Calculate the load to within 5 g, to produce 100
revolutions in 30 s by interpolating between the load weights recorded for the readings made between 27 and 33 s for 100 revolutions.
11.1.2 Correct the load determined for any deviation of the specimen temperature from the specified temperature (see Appendix XI).
11.1.3 If desired, determine from Table 1 the KU corre sponding to the load to produce 100 revolutions in 30 s.
No t e 4--Table 1 has been constructed so that it is not necessary to interpolate between toads to obtain the KU corresponding to the load to produce 100 revolutions in 30 s. The table provides KU values computed for a range of 27 to 33 s for 100 revolutions.
11.2 Procedure B: 11.2.1 If desired, determine from Table 2 the KU value corresponding to the load to produce 200 r/min.

XI. EFFECT OF SPECIMEN TEMPER. Tl
XI. I For maximum accuracy in determining the effect of specimen temperature on Stormer consistency, measure ments should be performed at three different specimen temperatures covering the range of interest. The change in load or KU per 1C change can be determined from these
results. XI .2 It has been observed that the consistency of an oil is
considerably more sensitive to temperature than is the

manufacturer's directions as to the application of the conver sion coating. Preparation of test panels may consist of one or ore steps of cleaning, rinsing, or conditioning prior to the application of the conversion coating. Additional rinsing uath water will usually be required after the conversion coating is applied. To prevent rust, force dry immediately after rinsing.
6.3 Procedure B: Vapor Degreasing--Suspend the panels in a vapor-phase type degreaser containing stabilized 1,1,1ttichloroethane and allow them to remain above the boiling solvent. When the panels attain vapor temperature, conden sation of vapor onto the panels no longer occurs. Prewiping with a clean lintless cloth saturated with mineral spirits may be necessary, since vapor degreasing generally does not remove solid particulate matter such as dirt, etc. (see Note).

10. Procedure
10.1 Place one test panel on the specimen stage. Pour a quantity of abrasive into the abrasive holder (funnel) of the apparatus. Lower the nozzle to touch the surface of the test specimen and close the door of the tester. Turn on the air supply and adjust it to the pressure reading established in the standardization of the apparatus.
10.2 Release the stream of abrasive by removing the pinchcock attached to the tubing, and allow to flow until the coating is wom through to the base metal. Consider the end point as having been reached when a small spot approxi mately 2 mm in diameter is wom through in the center of the wear pattern. When this point is reached, immediately shut off the abrasive stream and determine the weight of abrasive used.
N' 7--The amount of abrasive used can be determined either by
(7) weighing the abrasive in the funnel before and after a run, or by (2) opening the bottom ofthe abrasion tester, collecting the abrasive used in a container, and weighing the abrasive.
10.3 Repeat 10.1 and 10.2 for two additional locations on the test specimen.
10.4 Measure the thickness ofthe coating adjacent to each wear pattern.

3. Definition 3.1 cracking--that phenomenon manifested in paint films
by a break extending through to the surface painted. Where this is difficult to determine, the break should be called a crack only if the underlying surface is visible. The use of a magnification of 10 diameters is recommended in cases where it is difficult to differentiate between cracking and checking (see Test Method D 660).
4. Significance and Use 4.1 Cracking failure of paint films can occur in use. This
test method provides a means of evaluating the degree ofthe failure by comparing the pictorial standards.

' 19422. The silver halide-gelatin photographs are intended to be the only ""naiy reference standards for this method. The reproductions ofthem in this test bmhod are for the purpose of illustration only.
5.1.1 Irregular Pattern Type--Cracking in which the breaks in the film are in no definite pattern.
5.1.2 Line Type--Cracking in which the breaks in the film are generally arranged in parallel lines, usually either horizontally or vertically, over the surface of the film. These breaks often follow the line of brush marks.
5.1.3 Sigmoid Type--Cracking in which the breaks in the film form a pattern consisting of curves meeting and intersecting, usually on a relatively large scale.
6. Use of Photographic Reference Standards
6.1 The photographic reference standards that are part of this test method and are provided in the Pictorial Standards ofCoating Defects Handbook are representative of the degree of cracking of exterior paint films. Figures 1 and 2 are for illustration purposes only and should not be used for evaluation.
6.2 The use of the photographic reference standards3 illustrated in Fig. 1 requires the following precautions:
6.2.1 The accompanying photographic reference stand ards show line-type cracking only. Irregular and sigmoid-type cracking may also be interpreted from these photographs.
6.2.2 Care must be taken not to confuse various types of failure that may be present on the same surface. This is particularly true in observing cracking and checking. Cracking may very often be an advanced stage of checking and is very often in evidence along with checking and other failures.
6.2.3 It must be realized that the degree of failure will vary over any given area. Therefore, an average portion of the film should be used for comparison. On larger surfaces it is recommended that ratings be made at several locations and the mean and range reported.
6.2.4 Paint films may collect excessive quantities of dirt, which may mask the type and degree of failure. If necessary, dirt should be removed by careful and gentle brushing with a moderately soft brush.
6.2.5 In examining wood panels for cracking failure, the ` possibility of wood failure should be recognized. This takes the form of a cracking or splitting of the wood itself with a resultant rupture of the paint film. Also, some panels will develop "resin spewing" which will cause early failure by cracking. These points should be taken into consideration in any evaluations.

3. Definition 3.1 erosion--that phenomenon manifested in paint films
by the wearing away of the finish to expose the substrate or undercoat. The degree of failure is dependent on the amount of substrate or undercoat visible. Erosion occurs as the result of chalking. {See Method D 659 for evaluation of chalking.)

6. Use of Photographic Reference Standards
6.1 The photographic reference standards that are part of this test method and are provided in the Pictorial Standards ofCoatingJDefects Handbook are representative of the degree of erosion of exterior paint films. Figure 1 is for illustration purposes only and should not De used for evaluation.
6.2 The use of the photographic reference standards3 illustrated in Fig. 1 requires the following precautions:
6.2.1 Care must be taken not to confuse various types of failure that may be present on the same surface.
6.2.2 It must be realized that the degree of failure will vary over any given area. Therefore, an average portion of the film should be used for comparison. On larger surfaces it is recommended that ratings be made at several locations and the mean and range reported.
6.2.3 The photographic standards used represent various degrees of erosion of a white brushing type paint over a dark primer. This system was necessary to provide sufficient contrast for photographic purposes. The erosion of a film to its normal substrate is, however, readily visible to the naked eye so it may easily be compared to the standards and given a numerical rating.
6.2.4 In doubtful cases, erosion is sometimes more visible in a damp film than in a dry film. Also, with severe erosion, it is often easier to rate the degree of erosion in a damp film than in a dry film.
6.2.5 While erosion ofa sprayed film is more regular in its wearing away, a numerical rating can be given to it by interpreting the amount of erosion in terms of these stan dards.
6.3 For convenience in recording the data obtained, the records may be kept on forms such as Standard D 1150.4

5. Procedure
4'A in. (104 mm) 3% in. (85 mm) % in. (9.5 mm)
5.1 Prepare a test stripe at least 3 in. (75 mm) in width of the paint to be tested by a mechanical spreader, or other suitable means on a clean plate glass panel at a wet film thickness of- 15 0.5 mils. (Use a plate glass panel approximately 4 by 8 by Vis in. (100 by 200 by 3 mm).)
5.1.1 Record the time of application. Allow the panel to dry in a horizontal position under the laboratory conditions specified (73.5 3,ST (23 2C) and 50 5 % relative humidity).
5.1.2 Test the paints used with drop-in beads without beads unless otherwise specified or agreed upon between the purchaser and the seller.
5.2 Butt the glass plate against the ramp. At regular intervals remove the wheel from its rest, hold against the rest as a starting point, then free roll the weighted wheel down the inclined ramp and over the paint film with each roll of the wheel over a new wheel path. Position the wheel properly so that a clean surface of the wheel will come into contact with the paint film. As many as three passes of the wheel can be made before the wheel needs to be cleaned. This can be done with a rag saturated with acetone. It is best to set aside the wheel after washing until all the solvent has evaporated.
5.3 Note the end point for no-pick-up time when no paint adheres to the rubber rings of the test wheel when it is rolled over the paint film. As the end point is approached, roll the weighted wheel over the paint film every 30 s.
6. Report
6.1 Report the time elapsed between application of the paint and the end point as the drying time for no-pick-up of the traffic paint.
7. Precision and Bias
7.1 Precision--Because of the poor precision of this test method, if it is used in a specification, the maximum deviation from the maximum no-pick-up time specified should be agreed upon between the purchaser and the seller.

Standard Practice for Conducting Road Service Tests on Fluid Traffic Marking Materials*1
This standard is issued under the fixed designation D 713; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (f) indicates an editorial change since the last revision or reapproval.
NOTE--Paragraphs 9.4 and 9.5 were inadvertently deleted and were reinstated in February 1990.
1. Scope
I j This practice covers the determination of the relative service life of fluid traffic marking materials such as paint, thermoplastic, epoxy, and polyester products under actual road conditions using transverse test lines. Materials under test are applied under prescribed conditions and periodic observations are made using prescribed performance criteria.
1,2 This practice may involve hazardous materials, opera tions and equipment. This practice does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this practice to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
2. Referenced Documents
2.1 ASTM Standards: D711 Test Method for No-Pick-Up Time of Traffic Paint2 0913 Test Method for Evaluating Degree of Resistance to
Wear of Traffic Paint2
3. Significance and Use 3.1 This practice is an accelerated evaluation of bead
retention and wear characteristics of fluid traffic marking materials. It is used to determine the useful life of such markings in the field. The same procedures are applicable to evaluating longitudinal lines to determine service life.
4. Type and Location of Pavement for Tests
4.1 Select sections where traffic is moderate and freerolling with no grades, curves, intersections, or access points near enough to cause excessive braking or turning move ments, where wear is uniform with full exposure to the sun throughout daylight hours, and there is good drainage. Select surfaces that are representative of the pavements upon which the fluid traffic marking material will be used in practice. Such surfaces include portland cement concrete, sheet as phalt, bituminous concrete, rock asphalt, and bituminous surface treatment.
1 This practice is under the jurisdiction of ASTM Committee D-1 on Paint and Related Coatings and Materials and is the direct responsibility of Subcommittee 001.44 on Traffic Coatings.

5. Conditions at Time of Application
5.1 Clean the test area thoroughly of all foreign material. Do not apply traffic paint when the pavement surface is damp or wet nor when the pavement temperature is below 50F (KFC). Application between 10 a.m. and 3 p.m. is recommended. During application record air and pavement temperature hourly.
6. Measurement of Wet Film Thickness
6.1 To aid in obtaining the correct film thickness, a length of roofing paper placed by the side of the road can be used. Place a rigid metal test panel on the roofing paper and in the path of the test line. A 12 by 12-in. (300 by 300-mm) metal panel Vie in. (1.5 mm) in thickness is satisfactory. Immedi ately after the test line is applied by the motorized striper, read the wet film thickness. If the wet film thickness is not satisfactory, adjust the spray pressure and repeat until the target wet film thickness is attained. It is important that no glass beads or other interfering materials be present that would give a false wet film reading. When the wet film thickness is correct, apply a test line across a tared metal panel and weigh immediately. A balance must be immedi ately available and be thoroughly shielded from wind as well as be of 1500-g capacity with 0.1 g or better sensitivity. As a basis for determination of glass bead application (7.1) the weight of a paint line 4 by 12 in. (without consideration for solvent loss) can be calculated as follows:
W = 0.0943 X(XS
where: W = weight of paint line, g, t = mil thickness, and g = weight per gallon, lb.
7. Measurement of Glass Beads
7.1 After the completion of 6.1, apply another test line to a tared panel with the motorized striper, this time also adding the glass beads, and weigh immediately. The weight difference between this measurement and that in 6.1 gives the amount of glass beads on the panel. The process can be repeated if an adjustment in the bead application rate is needed. The weight of applied glass beads can be calculated as follows:
W -- 1.418 x B
where: W -- weight of glass beads, g, and B = glass beads per gallon of paint, lb.

8. Application Procedure
8.1 Apply the test stripes 4 in. (100 mm) in width and transversely on the road. At the option of the purchaser, the test stripes may be applied to the pavement at an angle of 45 to the direction of the traffic, or longitudinally in each wheel path, in order to increase the area of contact with traffic.
8.2 Apply test stripes (trained personnel under the super vision of the purchaser) by using a pavement-marking machine similar to the production pavement marking equip ment. Apply the test stripes to at least two sections of each road surface selected to ensure against undetected road surface problems. When more than one specimen is tested at more than one location, change the sequence of placement to minimize the effect of time of day and time period before the test deck is opened to traffic.
8.3 Apply at least two lines of each specimen in each section for better statistical reliability. A tared panel as used in the measurement of glass beads (see 7.1) should be placed between the wheel track ofone line's application as a double check for material and glass bead application rates. Weights between this reading and that found in 7.1 should agree within 0.5 g. The purchaser may wish to place another smaller panel between the wheel tracks to retain for future reference.
8.4 The road surface test lines have a wet film thickness within 0.5 mil of that required by the purchaser.
No t e 1--If no wet film thickness is specified, 15.0 mil is recom mended.
8.5 A fluid marking material with which the purchaser has had considerable production experience is included in the test series as a control.
8.6 Glass beads are placed in the paint film within 0.5 lb/gal of that required by the purchaser. All glass beads are supplied by the purchaser.
No t e 2--If no bead application rate is specified, 6.0 lb/gal of paint is recommended.
9. Performance Criteria
9.1 Auto-No-Track Time--The auto no-track time is determined by passing over the freshly applied line in a simulated passing maneuver with a standard size passenger car with regular treads (no snow treads). A line showing no visual pick-up and redeposition of the materials onto the pavement surface when viewed from a distance of 50 ft in the highway direction is considered as showing no pick-up and conforming to the drying time requirements.
9.1.1 The test line is applied at the same temperature, the same wet film thickness, and the same rate of glass beads as will be specified by the purchaser in production application.
9.1.2 The no-track maximum time is measured when the pavement temperature is from 60 to 120F (15 to 50C) and under local humidity conditions, providing that the pave ment is dry.
No t e 3--A laboratory no-track test is described in Test Method D711. This test is a laboratory control test and has little or no correlation with field results. Some paints have a tendency to skin over rapidly allowing the specimen to meet the maximum specified time for the laboratory test, but would be unsatisfactory at that time on a road
surface.
9.2 Appearance--The impression of the observer of the
general condition of the test lines when viewed without any
detailed inspection, from a distance of at least 10 ft. It is a measure of satisfactory or unsatisfactory appeal to the observer. It includes a comparison of the color of the surface under consideration with the original color, taking into account changes due to yellowing, bleeding, darkening, fading, dirt collection, mold growth, etc. This determination is made in each wheel track in an area extending 9 in. (229 mm) each side of the point of greatest wear. The appearance is rated either acceptable or unacceptable.
9.3 Durability--The durability is equal to one tenth of the percentages of material remaining on the pavement (when examined by the unaided eye). This determination is made in each wheel track in an area extending 9 in. (229 mm) each side of the point of greatest wear. The percent of paint remaining on the pavement is considered as the percent of the prescribed area of test stripe in which the substrate is not exposed. Make the evaluations in accordance with Test Method D 913. *
j ! l
N' 4--In the absence of a specification by the purchaser, failure
shall be a rating less than 4 (less than 40 % material remaining on the
pavement).
9.4 Night Visibility--Night visibility designates the ap. parent brightness when examined at night under tungsten illumination from the side of the road, with eye and light source separated by 1% in. (40 mm) that corresponds to an observation angle of approximately Vi". Night visibility determinations are made in the wheel track areas used for rating durability, and are based on a factor of 10 for a unexposed standard panel placed next to the test stripe and 0 for no apparent brightness.
N' 5--In the absence of a specification by the purchaser, failure
shall be a rating less than 4.
No t e 6--A new test method for night visibility using a retro-
reflectometer is being developed which is expected to have much greater
precision.
J
9.5 Length of Useful Life--The length of useful life is determined by the number of days of duration between the date the sample was applied to the road surface and the date any one of the designated measurements falls below the specified minimum rating.
10. Evaluation Procedure
10.1 Make periodic inspections of the test sections in accordance with 9.2, 9.3, and 9.4. Record at each inspection the general daytime appearance (including color), film con dition, and night visibility (retro-reflectance).
10.2 Inspect the test lines at regular monthly intervals. As the test lines approach failure, they should be evaluated every 2 weeks (weather permitting). The test lines must be evalu ated until failure. Different types of traffic paint and mark ings do not wear out in a linear manner. Hence, it is not possible to extrapolate to failure some intermediate data. The winter season is also a must when evaluating test lines.

MOTE 7--The cost of the glass beads is usually not included in the calculation because it will be a constant when comparing the relative performance of a specified class of paint Various types of paints and jlher fluid marking materials, however, can have different bead wetting characteristics, and beads with different wetting characteristics also are availably either of which could influence the useful life of the line, y/hen testing more than one type of material or one type of bead, the
optimum cost/performance may be at a different bead application rate than that recommended in 8.6.
11.2 To determine the relative performance of the dif ferent fluid traffic marking materials during the course ofthe test, the following weighted rating, R, can be used:
R = 030A + 0.30D + 0.40N
where:
A = appearance as defined in 9.2 and determined using a rating from 0 to 10,
D = durability as defined in 9.3, and JV = night visibility as defined in 9.4.

Standard Test Method for Evaluating Degree of Blistering of Paints1
This standard is issued under the fixed designation D 714; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year oflast revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<) indicates an editorial change since the last revision or reapproval.
This test method has been approvedfor use by agencies ofthe Department ofDefense to replace Method 6461 ofFederal Test Method Standard No. 141A andfor listing in the DoD Index ofSpecifications and Standards.
1. Scope 1.1 This test method employs photographic reference
standards to evaluate the degree of blistering that may develop when paint systems are subjected to conditions which will cause blistering. While primarily intended for use on metal and other nonporous surfaces, this test method may be used to evaluate blisters on porous surfaces, such as wood, if the size of blisters falls within the scope of these reference standards. When the reference standards are used as a specification of performance, the permissible degree of blistering of the paint system shall be agreed upon by the purchaser and the seller.
2. Significance and Use
2.1 A phenomenon peculiar to painted surfaces is the formation of blisters relative to some system weakness. This test method provides a standard procedure of describing the size and density of the blisters so that comparisons of severity can be made.
3. Reference Standards
3.1 The photographic reference standards are glossy prints.2 Figures 1 to 4 are reproductions of these standards and are included to illustrate two characteristics of blistering: size and frequency.
3.2 Size--Reference standards have been selected for four steps as to size on a numerical scale from 10 to 0, in which
1 This test method is under thejurisdiction of ASTM Committee D-I on Paint and Related Coatings and Materials and is the direct responsibility of Subcom mittee D01.27 on Accelerated Testing.
Current edition approved May 29, 1987, Published July 1987. Originally published as D 714 - 43 T. Last previous edition D 714 - 56 (1981).
2 Glossy prints of the photographic reference standards showing types of blistering are available at a nominal charge from ASTM Headquarters, 19 L6 Race St., Philadelphia, PA 19103. Request Adjunct No. 12-407140-00.
No. 10 represents no blistering. Blistering standard No. 8 represents the smallest size blister easily seen by the unaided eye. Blistering standards Nos. 6, 4, and 2 represent progres sively larger sizes.
3.3 Frequency--Reference standards have been selected for four steps in frequency at each step in size, designated as follows:
Dense, D, Medium dense, MD, Medium, M, and Few, F.
No t e l--A quantitative physical description of blistering would
include the following characteristics determined by actual count: Size distribution in terms of mensuration units, Frequency of occurrence per unit area,
Pattern of distribution over the surface, and Shape of blister For the usual tests, an actual count is more elaborate than is necessary.
4. Procedure
4.1 Subject the paint film to the test conditions agreed upon by the purchaser and the seller. Then evaluate the paint film for the degree of blistering by comparison with the photographic reference standards in Figs. 1 to 4.
5. Reporting
5.1 Report blistering as a number (Note 2) designating the size of the blisters and a qualitative term or symbol indi cating the frequency.
5.2 Intermediate steps in size or frequency of blisters may be judged by interpolation.
5.3 When the distribution of blisters over the area has a nonuniform pattern, use an additional phrase to describe the distribution, such as "small clusters," or "large patches."
No t e 2--The number refers to the largest size blister that is
numerous enough to be representative of the specimen. For example, photographic standard No. 4, "Dense," has blisters ranging in size from about No. 7 to No. 4, inclusive.

Standard Test Method for Evaluating Degree of Flaking (Scaling) of Exterior Paints1
This standard is issued under the fixed designation D 772; the number immediately following the designation indicates the year of original adoption or. in the case of revision, the year of last revision, A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This test method has been approvedfor use by agencies ofthe Department ofDefense to replace Method 6441 ofFederal Test Method Standard No. 141A andfor listing in the DoD Index ofSpecifications and Standards.
1. Scope 1.1 This test method covers the evaluation of the degree of
flaking (scaling) of exterior paints by comparison with photographic standards.
2. Referenced Documents
2.1 ASTM Standard: D1150 Single and Multi- Panel Forms for Recording
Results of Exposure Tests of Paints2 2.2 Other Standards: Pictorial Standards of Coating Defects Handbook3
3. Definition
3.1 flaking (scaling)--that phenomenon manifested in paint films by the actual detachment of pieces of the film itself either from its substrate or from paint previously applied. Flaking (scaling) is generally preceded by cracking or checking or blistering, and is the result of loss of adhesion, usually due to stress-strain factors coming into play.
4. Significance and Use 4.1 Flaking (scaling) failure of paint films can occur in
use. This test method provides a means of evaluating the degree of failure by comparing to pictorial standards.
5. Type of Flaking (Scaling) 5.1 Only one type of flaking (scaling) is recognized, as
defined in Section 3.
1 This test method is under the jurisdiction of ASTM Committee D-l on Paint and Related Coatings and Materials and is the direct responsibility of Subcom mittee D01.27 on Accelerated Testing.
Current edition approved Aug. 29, 1986. Published October 1986. Originally published as D 772 - 44 T. Last previous edition D 772 - 47 (1981)ei.
2 Annual Book ofASTM Standards, Vol 06.01. 3 Copies of the pictorial photographic reference standards are contained in the publication Pictorial Standards of Coatings Defects and may be obtained from the Federation of Societies for Coatings Technology, 492 Norristown Rd,, Blue Bell, PA 19422. The silver halide-gelatin photographs are intended to be the only primary reference standards for this method. The reproductions ofthem in this test method are for the purpose of illustration only.
6. Use of Photographic Reference Standards
6.1 The photographic reference standards that are part of this test method and are provided in the Pictorial Standards ofCoating Defects Handbook are representative of the degree of cracking of exterior paint films. Figure 1 is for illustration purposes only and should not he used for evaluation.
6.2 The use of the photographic reference standards2 illustrated in Fig. 1 requires the following precautions:
6.2.1 Care must be taken not to confuse various types of failure that may be present on the same surface.
6.2.2 It must be realized that degree of failure will vary over any given area. Therefore, an average portion of the film should be used for comparison. On larger surfaces it is recommended that ratings be made at several locations and the mean and range reported.
6.2.3 In technical literature, a distinction is sometimes made between flaking and scaling. In most cases, however, flaking and scaling refer to the same phenomenon. In some instances, the term flaking is used to describe the detachment of pieces of film less than 'A in. (6.4 mm) in size, and scaling, the detachment of pieces over lA in. in size. In other instances, the term flaking is used to describe the detachment of pieces of film from the immediate undercoat (intercoat failure) and scaling the detachment of pieces from the base (complete failure). It should be kept in mind that the flakes may vary widely in size and shape from those illustrated by the reference standards in Fig. 1, varying from a fraction of an inch to several inches in size.
6.2.4 Peeling is frequently due to a moisture condition and when this is evident it should be taken into consider ation in any evaluation.
6.2.5 For convenience in recording the data obtained, the records may be kept on forms such as Standard D f 150.4
7. Precision and Bias
7.1 No precision or bias statement has been established for this test method.

A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapprovaL
This standard has been approved for use by agencies cf the Department of Defense. Consult the DoD Index of Specifications and Standards for the specific year ofissue which, has been adopted by the Department cfDefense.
1. Scope
1.1 This practice covers accelerated exposure testing of paint, varnish, lacquer, and related products using filtered open-flame carbon-arc devices as described in Practice G 23. Two basic apparatus types are available for coating evalua tion since open-flame carbon-arc devices can be manufac tured with or without automatic humidity control. These are
Types E and EH as described in Practice G 23.2 Each type of device can be operated with different types ofglass filters that filter various amounts of ultraviolet (UV) radiation. All
references to use ofthis practice must include a description of the filter used. Table 1 describes commonly used test conditions. Interlaboratory comparisons must be made only with devices using the same filter type and test conditions.
1.2 Previous versions of this practice described exposures using either open-flame carbon arcs or enclosed carbon arcs.
,
N' 1--A new practice using enclosed carbon-arc exposure appa
ratus is under development. Another procedure for exposing these products is covered by Practice D 33<i 1 in which the specimens are subjected to radiation from an unfiltered open-flame carbon arc that produces much higher levels of short wavelength radiation than filtered open flame or enclosed carbon arcs. Only automatic humidity con trolled open-flame carbon-arc apparatus (Type EH) is applicable to Practice D3361.
1.3 This standard may involve hazardous materials, oper
ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish
appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 4.

3, Significance and Use
3.1 This practice is intended to evaluate coating films for their stability in apparatus that expose ultraviolet (UV) light and moisture. If die spectral power distribution of the light source used for exposure tests does not adequately simulate that of terrestrial solar radiation, it may produce a different type of degradation and distort the ranking of materials obtained in outdoor exposures. Figures 1 and 2 compare representative spectral power distributions of the open-flame carbon arc (with two different types of glass filters) with that ofterrestrial sunlight. Soda borosilicate glasses remove more short wavelength UV radiation than potash lithia glasses7 and their use can provide carbon-arc exposures that are a better approximation of terrestrial solar UV. Exposures using soda borosilicate glass filters will typically take longer to produce photochemical degradation.
3.2 No single operating procedure for light-exposure ap paratus with or without water can, be specified as a direct simulation of natural exposure. This practice does not ex press, or imply, a specific correlation with outdoor exposure.
3.3 Since natural environments vary with respect to climate, geography, and topography, it may be expected that the effects of natural exposures will vary accordingly. Fur thermore, all materials are not affected equally by the same environment. Therefore, results obtained by use of this practice should not be represented as equivalent to those of any natural weathering test until the degree ofcorrelation has been empirically established for the material in question.
3.4 Variations in results are possible between instruments of the same type operating within the accepted limits of this practice. It is recommended that results obtained using this practice be compared with those of a control or reference

panel holder, with test panel, at a uniform speed through the atomized spray produced by a fixed spray gun, or (2) it can move the gun, with atomized spray, at a uniform speed past the test panel mounted on a fixed panel holder. A machine equipped.with a programmable system can index the spray gun vertically for multiple passes and for multiple coats with selective time delay.
3.2 The thickness of coating applied is controlled by the traverse speed of the panel or gun, the fluid delivery rate of the gun, the viscosity of the material, and the amount of nonvolatile matter in the material.
4. Significance and Use
4.1 This test method should be used for those coatings that are designed for spray applications of objects in the factory or in the field. It is particularly important that it be used in the evaluation of metallic coatings for appearance properties, such as gloss and color.
4.2 Coatings applied by this test method may exhibit a slight orange-peel or spray wave.
5. Apparatus
5.1 Test Panels, of any smooth, planar material of a size that can be accommodated by the panel holder of the automatic spray machine.
5.1.1 When steel panels are used, they should be prepared in accordance with the appropriate method in Methods D609.
5.2 Automatic Spray Machine,3 equipped with a panel holder and a mounting for a spray gun. The machine shall be designed to move the panel holder at a uniform speed past the fixed gun mount, or designed to move the gun mount at a uniform speed past the fixed panel holder. The panel holder or the gun mount traverse speed shall be adjustable from 25 to 100 ft (7.5 to 30 m)/min. Typical machines are shown in Fig. 1.
N' I--Some automatic spray machines provide additional fea tures that can improve the uniformity of film preparation. Some
examples are: a z-bar panel holder, indexing of the panel holder at right angles to the gun to provide uniform lapping; and automatic control of number of passes, time between passes, and lapping distance.

METHOD B--MOTOR-DRIVEN DIP COATER APPLICATION
10. Summary of Test Method 10.1 A motor-driven device is employed to withdraw the
test panel from a container of the coating material at a desired uniform rate.
10.2 The thickness of coating applied isxontrolled by the speed of panel withdrawal, the viscosity of the material, and the percent of solids in the material.

flow oilt to smooth films When test panels are dipped into the material and withdrawn.
105
DUP050297288
# D 823
12. Apparatus
12.1 Dip Coaler,4 consisting of a mechanism that will withdraw a panel from a container ofthe coating material at a predetermined rate. Suitable apparatus, is shown in Fig.
2(a) and 2(6): 12.1.1 The apparatus shown in Fig. 2(a) uses a cord
wound around a step-cone pulley on the shaft of a motor to provide panel withdrawal rate of 2, 3, and 4-in. (50, 75, and 100-mm)/min. Prior to withdrawal, the panel, attached to the cord, is lowered by hand into the container holding the
material. 12.1.2 The apparatus shown in Fig. 2(0) uses a cord
driven by a variable-speed device that can provide panel immersion and withdrawal rates that are continuously vari able from 2.5 to 20 in. (65 to 510 mm)/min.
N' 5--Rectangular containers (F-style can with lid cut off) are
useful because the smaller exposed surfaces of the liquid coating reduces
volatile loss.
12.2 Test Panels, of any clean, smooth, rigid substrate ofa size that can be accommodated by the dip coater and the container.
12.2.1 When steel panels are used they shall be prepared in accordance with the appropriate method in Methods D609.
N' 6--The test panels should not exceed 12 in. (300 mm) in
length, but the width may be varied up to 12 in. if a suitable counterweight is used and a dip tank ofadequate size is provided. Use of a multiple hook will permit dipping several panels at one time.
13. Procedure
13.1 Adjust the coating material to the proper percentage of solids and viscosity. Measure the temperature of the material in the container at the time of application.
N' 7--The operating conditions (viscosity, percent of nonvolatile
matter, and rate of withdrawal) are specific for a given coating material
and film thickness and need to be determined by trial. Subsequent
reproduction of the same operating conditions should rive the same film
thickness. Data are available5 on a variety of materials and film
thickness to indicate the range required. The viscosity range for normal
film thickness of0.5 to 2.0 mil (13 to 50 mm) has been shown to be 1 to
2.5 P.
^
13.2 Place the prepared test panel on the hook attached tor the cord and lower it into the container holding the coating material. Wind the cord once completely around the pulley of the correct size to give the desired rate of withdrawal.
13.2.1 For the stepped-cone pulley apparatus, wind the cord once completely around the pulley of the correct size to
give the desired weight of withdrawal. 13.2.2 For the continuously variable speed apparatus set
the desired panel immersion and withdrawal rates on the
control panel. 13.3 Start the motor and withdraw the panel at the
desired rate, with a smooth movement entirely free of

5 Information covering viscosity, percent of solids, rates ofwithdrawal and film, thickness for a variety of finishing materials is given in the paper by Payne, H. F., "The Dip Coater, An Instrument For Making Uniform Filmsby the Dip Method," Industrial and Engineering Chemistry, Analytical Edition, Vd IS, 1943, p. 48.'

13.4 Determine the thickness ofthe coating in accordance with Test Methods D 1005, D 1186, or D 1400, whichever is appropriate.
13.5 If the coating thickness is too low, coat another panel using a slower rate of panel withdrawal. If the coating thickness is too high, coat another panel using a faster rate of panel withdraw.
13.6 Continue in this manner until a test panel having the desired film thickness is produced. Measure thickness on at least three different areas of the test panel to determine coating uniformity.
N' 8--With the dip coater, non-uniform thickness on a panel is
frequently obtained. Hence, ifthe film thickness is greater at the bottom than the top, the viscosity should be increased or the panel withdrawal speed should be reduced, or both.
14. Report
14.1 Report the following information: 14.1.1 Type of coating material, 14.1.2 Viscosity, temperature, and percent nonvolatile of coating material, 14.1.3 Rate of withdrawal, 14.1.4 Air temperature and relative humidity at time of application, and 14.1.5 Mean and range of dry film thickness values obtained.
15. Precision
15.1 The precisian of preparing coated panels by this test method depends on the type of coating applied and its thickness.
15.2 For most types of coatings, individual thickness readings taken over the surface ofthe applied coating can be expected to deviate from the mean by no more than 5 %.
METHOD C--MOTOR-DRIVEN BLADE FILM APPLICATION
16. Summary of Test Method
16.1 A uniform film is produced by an applicator blade that is pushed across the test panel at a uniform speed by a motor-driven device.
16.2 The thickness of coating applied is controlled by the clearance of the applicator blade and the viscosity and percentage of solids of the material.
17. Significance and Use
17.1 This test method is applicable to substrates consisting of smooth rigid materials, such as metal or glass, and of non-rigid materials, such as paper charts. It is more reliable for producing uniform films than is the use of hand-held draw-down applicators.

a test panel by the means of a spray gun hand-held by a person skilled in its use.
22.2 The thickness of coating applied is controlled by the traverse speed of the gun, the number of passes of the gun, the fluid delivery rate of the gun, the viscosity of the fflatwial, and the amount of nonvolatile matter in the material.
23. Significance and Use
23.1 This test method is applicable to the coating of substrates consisting of smooth, rigid materials, such as metal or glass. It is usually less reliable for producing uniform films than is the automatic spray method. However, films sufficiently uniform for most physical property tests of materials can be produced by a hand-heldspray gun oper ated by a person skilled in its use.
24. Apparatus
24.1 Spray Gun, any that will provide a uniform fan-type spray pattern at least 6 in. (150 mm) in width is satisfactory.
24.2 Air Pressure Gage, covering the range from 0 to 100 psi (0 to 690 kPa).
24.3 Air Pressure Regulator. 24.4 Air Supply, oil-free and under pressure. 24.5 Panel Holder.
25. Preparation of Apparatus
25.1 Connect the air line hose from the regulator to the air pressure gage which in turn is connected to the air inlet of the spray gun.
25.2 With the trigger fully open, adjust the air regulator to provide the desired reading on the air pressure gage.
N' 12--A suitable air pressure is usually from 40 to 75 psi (275 to
520 kPa).
26. Procedure
26.1 Strain the material to be sprayed into the container to be used with the spray gun. Reduce the material to a viscosity suitable for spraying.
26.2 Connect the container to the gun and test the spray gun operation for correct spray pattern and uniformity by allowing a momentary spray to be deposited on a piece of paper placed in the panel position. Adjust the air pressure?, material flow, and spray width controls until the desired pattern and uniformity are obtained. Further refinements may be made in the spray pattern by modifying the air pressure, the type of thinning agent, and the consistency of the material.
N' 13--The width of the spray pattern should be considerably wider than the width of the test panel to assure spray uniformity on the test panel.
26.3 Place a test panel on the panel holder. Hold the spray gun tip 10 to 12 in. (250 to 300 mm) from the test panel surface and trigger the spray gun. Begin by aiming the gun at right angles to the panel so that the spray pattern is just beyond the edge of the panel. Gradually make the spray pattern move across the panel at a traverse speed of 10 to 15 in. (250 to 400 mm)/s.
26.4 Reverse the traverse direction of the spray gun and make the spray pattern move across the panel again.
26.5 Remove the panel from its holder and bake or
air-dry the coating, in accordance with its type, in a horizontal position in a dust-free atmosphere in accordance with Specification D 3924.
26.6 Clean the spray gun with solvent. 26.7 Measure the film thickness ofthe dry applied coating in accordance with Test Methods D 1005, D 1186, or D 1400 whichever is appropriate. 26.8 Ifthe coating thickness is too low, coat another panel using more passes of the spray pattern. If the coating thickness is too high, coat another panel with fewer passes of the spray pattern or, ifthis is not feasible, reduce the material further with thinner.

28. Precision
28.1 The precision of preparing coated panels by this test method depends on the type of coaling applied, and its thickness and the skill of the operator.
28.2 For most types of coatings, individual thickness readings taken over the surface of the applied coating can be expected to deviate from the mean by no more than 10 % if the coating has been applied by a skilled operator.
METHOD E--HAND-HELD BLADE FILM APPLICATION
29. Summary of Test Method
29.1 A uniform film of a coating material is produced on a test panel by the means of a hand-held applicator blade.
29.2 The thickness of coating applied is controlled by the rate at which the applicator blade is drawn across the test panel, the viscosity of the material, the amount of nonvola tile matter in the material, and the clearance of the blade.

32.1 Select an applicator blade that has a clearance that will provide a wet film thickness that should result in % desired film thickness.
32.2 For coating rigid substrates: 32.2.1 Position the applicator blade near the edge of the panel and place a pool of the liquid material in front of it. 32.2.2 Grasp the sides of the applicator with the fingers and pull it across the panel at a speed of about 10 to 12 in.
(250 to 300 mm)/s. 32.3 For coating non-rigid substrates: 32.3.1 Position the applicator blade near the edge of the
panri and place a pool of the liquid material in front of it. Place the auxiliary bar in front of the pool of material (see
fig-4). 32.3.2 Grasp the sides of the applicator with the fingers
and pull it across the panel at a speed of about 10 to 20 in. (250 to 500 mm)/s. As the auxiliary bar is pushed by the applicator, it should press the substrate flat adjacent to the advancing edge of the applicator.
32.4 Bake or air-dry the applied coating, in accordance with its type in a horizontal position in a dust free atmo sphere in accordance with Specification D 3924.
32.5 Clean the applicator bar with solvent. 32.6 Measure the film thickness ofthe dry-applied coating in accordance with Test Methods D 1005, D1186, or D1400 whichever is appropriate.
32.7 If the coating thickness is too low, select an appli cator blade with a greater clearance and coat another panel. If the coating thickness is too high, select an applicator blade with a smaller clearance and coat another panel.
33. Report
33.1 Report the following information: 33.1.1 Type of coating material, 33.1.2 Viscosity and percent nonvolatile of coating mate rial, 33.1.3 Clearance of applicator blade used, 33.1.4 Air temperature and relative humidity at time of application, and 33.1.5 Mean and range of the film thickness values obtained.
34. Precision
34.1 The precision of preparing coated panels by this test method depends on the type of coating applied, its thickness and the skill of the operator.
34.2 For most types of coatings, individual thickness readings taken over the surface of the applied coating can be expected to deviate from the mean by no more than 10 % if the coating has been applied by a skilled operator.

4. Significance and Use
4.1 Solvents in a traffic paint may cause bleeding of pavement constituents into the traffic marking, thereby rendering the traffic marking less effective as a lane or directional indicator. This test method in conjunction with the method for panel preparation in Test Method D 969 is used to evaluate such bleeding properties. The evaluation is very subjective and raises questions as to the usefulness of the results for specification compliance.
5. Use of Photographic Reference Standards
5.1 The photographic reference standards that are part of this test method2 are representative of the degrees of bleeding of traffic or pavement marking paints. The photograph in Fig. 1 is for illustration purposes only and should not be used
for evaluation. 5.2 The use of the photographic reference standards
shown in Fig. 1 should be as follows: 5.3 In preparing films to compare with the reference
standards for evaluating the extent of bleeding, the paint shall be applied to:
5.3.1 A nonbleeding reference surface, and 5.3.2 The test surface. 5.4 The paint under test shall be applied at a film thickness sufficient to ensure complete hiding. 5.5 The contrast in color between the films over the nonbleeding reference surface and the test surface shall be compared with the reference standards in Fig. 1 for a numerical rating.
N' --The degree of bleeding must necessarily be a function ofboth :
the bleeding surface agreed upon and the initial color of the paint For
instance, a yellow paint in general would be expected to show less
bleeding than a white paint since its initial color is darker and as a consequence the discoloration effect of the bleeding surface upon this I
darker color will be minimized.

3. Significance and Use
3.1 Paints, if not formulated or processed properly may settle excessively. Paint that settles excessively is difficult to reincorporate into the paint system causing time delays or valuable pigment being left in the drum. This test method is an attempt to evaluate the degree of settling caused by the accelerated Test Method D1309. This very subjective method of evaluation in conjunction with the variables of Test Method D 1309 raises questions as to the usefulness of the results for specification compliance.

5. Procedure
5.1 Place the specimen to be tested for pigment suspen sion in a 1-pt (500-mL) container, filling the can to within lh in. (13 mm) of the top. Gose the can tightly and hold undisturbed for shelf aging for 6 months or for such other periods of time agreed upon between the purchaser and the seller.
5.2 Open the can holding the shelf-aged sample without shaking or agitation, and examine the sample without removal of supernatant vehicle. Use the spatula to determine the extent and character of portions of the paint that may
have separated during storage. Prepare a suitable spatula for this purpose by cutting the tip from an ordinary 5-in. (127-mm) flexible steel laboratory spatula to the specified length. Hold the spatula perpendicular to and in the center area of the paint at a height whereby the bottom edge of the spatula is level with the top of the can. Drop the spatula from that position. Rate the condition of the sample in accordance with 5.4.
5.3 After examination of the entire specimen as described in 5.2, if a portion of the pigment has separated out to form a firm cake at the bottom of the container pour the supernatant portion of the liquid off into a clean container and hold for subsequent use. Reincorporate the separate cake by hand stirring with the spatula, adding back the liquid in small amounts until the pigment has been reincorporated to form a homogeneous paint suitable for the intended use or until it is determined that the pigment cake cannot be reincorporated by hand stirring. Rate the condition of the specimen in accordance with 5.4.
5.4 Rate the sample for degree of settling on a scale from 10 to 0 in accordance with the following. Give intermediate conditions the appropriate odd number.

3. Summary of Practice
3.1 Coated specimens are partially or wholly immersed in water in a container that is resistant to corrosion. The exposure conditions are varied by selecting: (a) the tempera ture of the water, and [b) the duration of the test. Water permeates the coating at rates that are dependent upon the characteristics of the coating and upon the temperature of the water. Any effects such as color change, blistering, loss of adhesion, softening, or embrittlement are observed and reported.
4. Significance and Use
4.1 Immersion in water can cause the degradation of | coatings. Knowledge on how a coating resists water immer sion is helpful in predicting its service life. Failure in a water immersion test may be caused by a number of factors including a deficiency in the coating itself, contamination of the substrate, or inadequate surface preparation. The test is therefore useful for evaluating coatings alone or complete coating systems.
4.2 Water immersion tests are used for research and development of coatings and substrate treatments, specifica tion acceptance, and quality control in manufacturing. These tests typically result in a pass or fail determination, but the degree of failure may also be measured. A coating system is considered to pass if there is no evidence of water-related failure after a specified period of time.
4.3 Results obtained from water immersion tests in accor dance with this practice should not be represented as being equivalent to a period of exposure to water in the natural environment, until the degree of quantitative correlation has been established for the coating or coating system.
4.4 Corrosion tests of a scribed coating on a ferrous substrate are impractical in water immersion tests as the corrosion products tend to contaminate the water bath | Continuous overflow of the test tank is sometimes required | to maintain consistent water quality.
4.5 The apparatus for the test is relatively inexpensive and] can be as simple as a glass beaker with a stirrer. It is

Continuous replacement of the water is permitted. 7.5 Conclude the test after a specified period of time or
after effects from water immersion have been observed. 7.6 Wipe the test specimens dry. Rate specimens for
changes in color, blistering, etc. Evaluate specimens no less than 5 min and no more than 10 min after removal from test, as the effects from water exposure can change within a short time. Remove only as many specimens as can be rated within the specified time.
N' '4--The 0 to 10 scale described in ASTM STP 5006 is preferred
for rating. Relevant procedures for evaluating water effects are described in Test Methods D 610, D 714, D 2616, D 3359, and D 3363.
7.6.1 If possible, rate the specimens again after they have been removed from the test for a recovery period long enough that moisture absorbed within the specimens dries out and the specimens reach moisture equilibrium with room air. A recovery period from 12 to 24 h is generally sufficient. The post-recovery rating allows evaluation of the permanent effects of the exposure as distinct from the transient effects, and is especially important for evaluation of color and gloss.

3. Description of Term Specific to This Standard 3.1 failure, described by these reference standards--that
condition manifested in traffic paint by actual detachment of entire sections of the film from its substrate or from paint previously applied. The degree of resistance to failure is judged by the amount of substrate that is covered.
5. Type of Failure
5.1 The failure as described in Section 3 does not presume any specific mechanism, and all areas where the substrate is visible shall be considered a failure.
6. Use of Photographic Reference Standards
6.1 The photographic reference standards3 that are part of this test method are representative of the degrees of resist ance to wear of stripes of traffic paint. The examples shown in Fig. 1- are for illustration purposes only and should not be used for evaluation.
6.1.1 The degree of resistance to wear is likely to vary over any given area. It is therefore necessary to use one of the following grading methods:
6.1.1.1 Select an area as representative and base the rating of the stripe on this area or
6.1.1.2 Grade segments of the stripe and average these gradings.
6.1.2 The photographic reference standards (Note) repre sent four degrees (97 %, 92 %, 77 %, 60 %) of resistance to wear. Substrate revealed by failure is readily discernible with the naked eye.
N' --The reference standards are representative ofstripes of traffic
paints. The percentage of surface covered is shown on each reference standard.
4 Significance and Use
4.1 This test method is designed to evaluate the resistance to wear of a traffic paint. It must be remembered that a high degree of performance ofpaint applied to a bare road surface may not guarantee similar results when the same paint is applied over old paint lines.
1 This test method is under the jurisdiction of ASTM Committee D-l on Paint and Related Coatings and Materials and is the direct responsibility of Subcom mittee D01.44 on Traffic Coatings.

1. Scope
1.1 These test methods cover the determination of the resistance of organic coatings to abrasion produced by abrasive Ming onto coatings applied to a plane rigid surface, such as a metal or glass panel.
1.2 Two test methods based on different abrasives are-
covered as follows:
Sections
Method A--Falling Sand Abrasion Test Method B--Falling Silicon Carbide Abrasion Test
1-12 13-19
1.3 These methods should be restricted to testing in only one laboratory when numerical values are used because of the poor reproducibility of lie methods {see 13.1.2 and 21.1.2). Interlaboratory agreement is improved significantly when ranking is used in place of numerical values.
1.4 This standard does not purport to address the safety
problems associated with its use. It is the responsibility ofthe
user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory
limitations prior to use.

3. Terminology
3.1 Description of Term Specific to This Standard: 3.1.1 abrasion resistance--the amount of abrasive re quired to wear through a unit film thickness of the coating.
4. Summary of Test Methods
4.1 Abrasive is allowed to fall from a specified height through a guide tube onto a coated panel until the substrate becomes visible. The amount of abrasive per unit film thickness is reported as the abrasion resistance of the coating on the panel. Silica sand or silicon carbide may be used, as specified.
5. Significance and Use
1
5.1 Silica sand produces a slower rate of abrasion for f
organic coatings than provided by silicon carbide but, for :
some types of coatings, it provides greater discrimination.
5.2 The abrasion resistance scales produced by the two
methods differ, but the methods provide approximately the 1
same rankings of coatings for abrasion resistance.
!
5.3 Each of the methods has been found useful for rating j
the abrasion resistance of specific types of coatings. For f
example Method A (Ming sand) has been used for rating ;
floor coatings while Method B (falling silicon carbide) has !
been used for rating coatings for ship decks.

62 Standard Abrasive--Natural silica sand from the St. Peters or Jordan sandstone deposits (located in the central United States) shall be considered standard when not more than 15 % of die grains in a sample are retained on a No. 20 (850 pm) sieve and not more than 5% of the grains pass a No. 30 (600 pm) sieve after 5 min of continuous sieving. The sand is characterized by its roundness of grains and its txceptionally high silicon dioxide content. Use the sieves described in Specification Ell'.
N' 1--The. abrading qualities of sand obtained from different sources may differ slightly, even though the sand meets the sieve leqmrements. Therefore, for maximum precision of test results, pur chaser and seller should use sand from the same source.6
I Test Specimens
7.1 Apply uniform coatings of the material to be tested to plane, rigid surface such as a metal or glass panel. Prepare minimum of two coated panels for the material.
7.2 Cure the coated panels under the conditions of and temperature agreed upon between the purseller.
N' 2--The coatings should be applied in accordance with Test "`'tads D 823, or as agreed upon between the purchaser and the seller.
N' 3--The thickness of the dry coatings should be measured in
8. Standardization 8.1 Pour a quantity of standard sand into the funnel.
Examine the sand stream falling from the lower end of the guide tube and align the apparatus by means of the adjusting screws in the base until the inner concentrated core of the sand stream falls in the center of the flow when viewed at two positions at 90 to each other. Introduce a measured volume of sand (2000 10 mL is a convenient amount) and determine the time of efflux. The rate of flow shall be 2 L of sand in 21 to 23.5 s.
8.2 Secure a trial panel in the testing position, as described in 6.1, and introduce the sand in increments until a spot %2 in. (4 mm) in diameter is worn through to the base material. The overall abraded area shall be elliptical in shape, about 1 in. (25 mm) in width and IV* in. (30 mm) in length. The center of the "area of maximum abrasion shall be on the centfer line through the longer axis ofthe abraded pattern and within 9/ie to "/is in. (14 to 17 mm) of the top edge. Slight final adjustment ofthe instrument may be required to center the abrasion spot in the pattern. A final check on alignment is made by determining the amount of sand that passes through a 3/32-in. (4-mm) hole in a metal panel placed directly under the tube. Place a container under the hole in the panel and allow a weighed amount of sand to pass through the tube onto the panel. Weigh the amount of sand that passed through the hole into the container. The appa ratus can be considered to be in calibration if the amount of sand that passed through the hole is 90 to 93 % of the

10. Procedure
10.1 Mark off on each coated panel three circular areas, oarh approximately 1 in. (25 mm) in diameter, and so arranged that each can be properly positioned in the panel support of the abrasion tester. Measure the thickness of the coating by Test Methods D 1005, D 1186, or D 1400 in at least three locations in each area. Record the mean of each set of measurements as the thickness of the coating over the respective area.
10.2 After conditioning, secure the coated panel in the tester as described in 6.1. Adjust the panel so that one of the marked areas will be centered under the guide tube. Pour standard sand, measured voiumetrically, into the funnel. Withdraw the gate and allow the sand to flow through the guide tube and impinge on the coated panel. Collect the sand in a container located at the bottom of the tester. Repeat this operation until a %2-m. (4-mm) diameter area of the coating has worn through to the substrate. A convenient increment of sand to employ during the test is 2000 10 mL. As the end-point is approached, increments of 200 2 mL may be introduced into the funnel.
13. Precision7
13.1 On the basis of an interlaboratory test of this test method in which three laboratories tested four types of coatings differing in their abrasion resistance, the withinlaboratory coefficient of variation was found to be 9 % with 22 degrees of freedom and the between-laboratories coeffi cient of variation 35 % with 7 degrees of freedom. Based on these coefficients, the following criteria should be used for judging the' acceptability of results at the 95 % confidence level.
13.1.1 Repeatability--Two results, each the mean ofthree runs, obtained by the same operator should be considered suspect ifthey differ by more than 25 % oftheir mean value.
13.1.2 Reproducibility--Two results, each the mean of three runs, obtained by operators in different laboratories should be considered suspect if they differ by more than 118% of their mean value.
N' 7--The reproducibility of this test is improved substantially
when rankings of the coatings by magnitude of abrasion resistance ate used. In the interlaboratory test for evaluating precision, ail laboratories ranked the coatings in the same order.

5.2 Procedures B and D--Free films of the test material are required. Alternatively, the test materials can be applied to an appropriate substrate in order that they can be removed as free films without deformation. If the method of specimen preparation affects the film forming properties of the test material or requires cutting or scraping to remove the ftee film, use Procedures A or C instead.
5.2.1 Free films may be prepared in accordance with Test Method D 2370.
6. Procedure
6.1 Procedure A: 6.1.1 Mount the test panel rigidly on a suitable base. Clamp or hold it to the base in such a way that there will be no movement or spring of the panel during the film thickness measurement. 6.1.2 Close the gage slowly until contact is made, but without visible distortion of the film. Read the gage, esti mating to 0.1 mil (2.5 pm), and record the reading. 6.1.3 Open the gage and remove the film carefiilly from the area where the measurement was taken. Any suitable means, chemical or mechanical, may be used to remove the film, taking care not to distort the panel. Close the gage, slowly on the area from which the film was removed, and take a reading, estimating to 0.1 mil (2.5 pm). 6.1.4 The difference in the gage readings before and after the removal ofthe film is the thickness ofthe film. Record to 0.1 mil (2.5 pm). 6.1.5 As an alternative to the above, the panels may be measured in distinct locations prior to the application of the coating, and again in the identical locations after the coating has cured. The difference represents the coating thickness. 6.1.6 Take a sufficient number of readings to characterize the panel. A recommended minimum is three determina tions for a 3 by 6-in. (75 by 150-mm) panel and more in proportion to size. 6.2 Procedure B: 6.2.1 Mount a smooth uncoated test panel rigidly on a suitable base. Clamp or hold it to the base in such a way that there will be no movement or spring of the panel during the film thickness measurement Figure 1 illustrates one satisfac tory way of rigidly mounting the panel for measurement. 6.2.2 Close the gage slowly until contact is made. Read the gage, estimating to 0.1 mil (2.5 pm), and record the reading. 6.2.3 Open the gage and lay a free film of the test material on the panel in the same area where the measurement was taken. Close the gage slowly with care not to distort the film and take a reading, estimating to 0.1 mil (2.5 pm). 6.2.4 The difference in the gage readings is the thickness ofthe film. Record to 0.1 mil (2.5 pm).
6.2.5 When conditions permit, perform a minimum of three determinations adjacent to one another on each film.
6.3 Procedure C: 6.3.1 Hold the hand-held micrometer in such a manner 4at the micrometer can be steadied against a film surface. Separate the micrometer anvils to a distance at least twice that of the film thickness to be measured. 6.3.2 Place the coated base material between anvil con-
FIG. 1
tacts. Be sure to align the panel so that it is perpendicular to the contact points. Carefully bring the micrometer anvil into contact with the film by releasing the spring tension or rotating the adjustment barrel. Do not compress the film.
6.3.3 Record the film thickness to 0.1 mil (2.5 pm). For spring-loaded micrometers, record the value directly from the dial indicator. For barrel micrometers, record the value using the instrument in the friction mode. The friction mode allows the thimble sleeve to slip without further turning the measuring screw. The friction mode provides for a consistent measuring pressure from panel to panel.
6.3.4 Open the gage and remove the film carefully from the area where the measurement was taken. Any suitable means, chemical or mechanical, may be used to remove the film, taking care not to distort the panel. Close the gage, slowly on the area from which the film was removed, and take a reading, estimating to 0.1 mil (2.5 pm).
6.3.5 The difference in the gage readings before and after the removal ofthe film is the thickness ofthe film. Record to 0.1 mil (2.5 pm).
6.3.6 As an alternative to the procedures in 6.3.2 through 6.3.5, the panels may be measured in distinct locations prior to the application of the coating, and again in the identical locations after the coating has cured. The difference repre sents the coating thickness.
6.3.7 Take a sufficient number of readings to characterize the panel. A recommended minimum is three determina tions for a 3 by 6-in. (75 by 150-mm) panel and more in proportion to size.
6.4 Procedure D: 6.4.1 Hold the hand-held micrometer in such a manner that the micrometer can be steadied against a film surface. Separate the micrometer anvils to a distance at least twice that of the film thickness to be measured. 6.4.2 Place the free film to be measured between anvil contacts. Be sure to align the film so that it is perpendicular to the contact points. Carefully bring the micrometer anvil into contact with the film by releasing the spring tension or rotating the adjustment barrel. Do not compress the film. 6.4.3 Record the film thickness to 0.1 mil (2.5 pm). For spring-loaded micrometers, record the value directly from

3.1 The procedure described in this practice is intended to aid in evaluating the performance of house and trim paints applied to new, previously unpainted wood.
3.2 Since natural environment varies with respect to season, geography, and topography, test results can vary in accordance with location and may not correlate to actual in-service performance (5.1).

types of paints to be tested, the range in climatic conditions to be met, also the types of woods and structures on which the paints are to be used are important factors to be considered in establishing the exposure program.
5. Location of Test Stations
5.1 The climatic conditions of the test sites should be representative of those of the area in which the paints are to be used. The type and rate of failure of a paint film will vary when exposed to different combinations of climatic and atmospheric conditions. For reliable results, exposure sites should be selected that are representative geographically, climatically, and in atmospheric contaminations with those of the locality in which the paint will be used. To obtain conclusions that are valid for paints with national distribu tion requires exposure at several sites, selected to cover a wide range in climatic conditions.4
6. Exposure Positions
6.1 Panels for testing house paints and trim paints should be exposed on vertical test fences facing both south and north. In comparisons where dirt collection and mildew resistance are not pertinent, north vertical exposures may be omitted. There should be no obstructions close enough to shade test panels from the sun more than 2 h after sunrise, or 2 h before sunset.
6.2 In the case where it is desirable to expose coated panels in a sheltered area, such as under eaves, a suitable test fence with a sheltered or eave arrangement can be used (see Annex).
7. Construction of Test Fences
7.1 Test fences should be durable and rigid enough to remain upright under the action ofprevailing winds and frost throughout the. contemplated period: of testing.5
7.2 Lower edges of test panels, when mounted on test fences, should be at least 18 in. (460 mm) above ground level to avoid dampness and mud splash. Backs of painted boards or plywood should be protected against direct exposure to the weather by methods such as, (/) having panels on both

11. Application of Paints
8. Sffrntinn of Woods for Test Panels 8.1 Paint need be tested only on woods on which it is
likely to be used in practice. Conclusions drawn from tests mode 0n a limited variety of woods, however, should not be generalized for woods of other kinds.
N' --See Specification 0 358.
8.2 Prior to use, test lumber and panels should be stored under such conditions that the moisture content of the wood will' be maintained within the normal range for exterior woodwork in the region in which the tests are made.
9. Construction of Test Panels
9.1 For house paints, unless the pattern of the siding requires some other choice, test panels should be made of one or the other of two patterns of siding, namely, % or 3A by 6-ia (13 or 20 by 150-mm) bevel siding or 1 by 6-in. (25 by 150-mm) drop siding.
9.2 Ifthe panels in the house paint test are not subdivided, one 3-ft (900-mm) length of 6-in. (150-mm) siding will be acceptable. Ifthe panels are subdivided, two 18-in. (460-mm) lengths are sufficient Exposures on wood panels should preferably be carried out on three panels to allow for variations in the wood.
9.3 For trim paints, the test panel should carry 1 by 4-in. (25 by 100-mm) pieces of trim lumber at each end.
9.4 A test panel of 1.5 fit2 (1400 cm2) or more in area, as provided in 9.2, may be subdivided into two or more test areas each not less than 10 in. (250 mm) long and 0,75 ft2 (700 cm2) in area. Each test area is for painting with a different paint. Paints placed on the test areas of one panel famish a comparison as to behavior.
9.5 When it will not interfere with the properties to be tested, all panels should be coated on the back to prevent warping.
10. Control or Comparison Paint for Extending the Compar isons
11:1 Ail tests that are to be compafed closely with one another should be placed on exposure as nearly simulta neously as possible. When a group of tests is too extensive for completion within a month, use a control paint or duplicate of at least 5 % ofthe test areas at successive exposure periods.
11.2 It is best in theory and practice to do the painting out-of-doors in proper weather for painting; however, indoor painting is permissible provided no more than 1 week6 elapses between successive coats and between applying the last coat and exposing on the test fence; and provided, further, that all painting is done under essentially the same drying conditions. It is necessary to allow each coat to cure sufficiently before top coating.
11.3 Preferred procedure is to apply paints with the test panel in a vertical position and kept vertical until the paint has set. If paint is spread on horizontal panels, the panels should be placed vertically immediately thereafter.
11.4 Records should be kept of the spreading rates at which paints are applied. When the purpose of the tests is to compare commercial paints, it may be appropriate to let the painter apply them at what seems to be their natural spreading rates. When the purpose is to study variation in paint composition, application should usually be at suitable predetermined spreading rates which can be controlled by applying a given weight or volume of coating to a measured
area.
12. Inspections and Records
12.1 After panels have been exposed to the weather, inspections should be made after not more than 1 month, at 3 months, and at intervals of 3 months during the first 2 years, and every 6 months thereafter. Midwinter inspections, however, may be omitted in northern latitudes.7 8Inspections may be made more frequently if desired. Usually the exposures should be continued for a considerable length of time after deterioration has reached the point at which best practice calls for repainting.
12.2 Records should be kept on forms such as Standard D 1150. ,,

ANNEX
(Mandatory Information)
Al. CONSTRUCTION OF TEST FENCE AND TEST PANELS
A 1.1 The plan for test fence and panels described in this Annex conforms to the principles set forth in this practice. It
nresents only one of numerous possible embodiments of
Jhe principles recommended. Al.2 Construction of Test Fence:
Al'2.1 The test fence, or test rack, runs east and west, and . instructed to hold test panels on both sides so that there
pflfwk facing both north and south. There are two rows
panels, one above the other, on each side of the fence. A
off cap is placed along the top of the fence, and projects approximately 1 in. (25 mm) beyond the face of the
mounted panels. The fence must be sufficiently sturdy in instruction to withstand strong winds. It is mounted on wood posts that are impregnated with creosote under Pres pa in accordance with Fed. Spec. TT-W-571b.
Al .2.2 Figure A1.1 shows one span or unit. The fence can be extended to as many units as the site permits or as are eeeded for the number of exposure tests to be made. ^irinnal fences may be built parallel to one another, but they should be spaced far enough apart to keep each fence jiom casting shadows on the adjacent fences during all but the first 2 h after sunrise and the last 2 h before sunset at the time of the winter solstice.
Al.2.3 When cleated panels of drop siding, which do not have backing, are used, there shall always be a pair of panels, one feeing north and one facing south, to give the backs mutual protection from the weather. If for any reason there are panels on one side only of the fence, the other side shall be covered with roofing paper or other covering to protect the backs of the panels.
A 1.3 Construction of Test Panels: A1.3.1 Home Paints--The boards of siding are assembled in a manner similar to house construction. Five pieces of Vi by 6-in. (13 by 150-mm) bevel siding are nailed securely on a backing of `A-in. (6-mm) plywood exterior grade, as shown in
Fig: A 1.2. The top board is a blank connecting board, cut to narrower width and painted as hereinafter described. The other four boards are test boards: they may be all of one species or two each of two different species. The overlap between boards should be not less than 1 in. (25 mm). Cadmium- or zinc-coated nails, 1 Vis in. (28 mm) long, should be used and should be spaced as indicated, and clinched on the back. The lower edge of the bottom board is shimmed out from the plywood with a wood shim and the bottom board projects '/* in. beyond the shim in order to permit insertion of a panel underneath. The top of the panel, which

is a blanlf board precoated with chalk-resisting exterior paint such as aluminum paint, is cut to a width of 4Vi in. {115 mm); the cutting makes a suitable shim for use under the bottom board. The plywood projects VS in. beyond the boards at the ends and 1 in. (25 mm) at the bottom; at the top the plywood projects 2 in. (50 mm) beyond the top ofthe second board and is overlapped by about 2lh in. (65 mm) by the top blank board. Holes are bored through the top blank board as indicated to permit positioning of the panel on the fence by means of small pegs. Holes are bored through the projecting ends of the plywood to permit secure fastening of the panels to the fence by means of wood clamps held in position by bolts with wing nuts as indicated (see also Fig.
A1J). A1.3.I.I Panels made of 6-in (150-mm) drop siding
jh/vilH consist of four test boards 37 in. (940 mm) long, and a narrow blank connecting board 3 in. (75 mm) wide, fitted
snugly together and held by three cleats, % by 2 in. (16 by 50 mm) wide, nailed firmly on the backs. By adjusting the width
of the blank connecting board the dropsiding panels can be
made to lit on fences designed as shown in Fig. A 1.1, although it may be impracticable to mount both types of panel together on the same fence.
Al.3.2 Trim Paints--An example of a panel for testing trim paint is shown in Fig. A 1.3. It is a modification of the panel shown in Fig. A 1.2. The modification consists in shortening the pieces of siding to 27 in. (685 mm) to make room for two pieces of trim lumber, 1 by 4 in. (25 to 100 mm), at each end; and in narrowing the exposed width ofthe siding to 4 in. to make room for another piece of trim lumber, 1 by 6 in. (25 by 150 mm), across the top. This piece is undercut, as shown in the sketch, so as to fit over the siding. The cap may be made of galvanized iron, aluminum, or painted iron. No blank connecting boards between two panels are needed. The panel may be fastened to the fence in the same way as the body paint panel. A much less elaborate panel, satisfactory in many cases, is merely a plain board, approximately 1 by 6 by 36 in. (25 by 150 by 915 mm).

3. Significance and Use
. 3.1 The procedures described in this test method are intended to aid in" evaluating performance of coatings on either new or previously rusted steel.
3.2 Since the natural environment varies with respect to season and geographic location, test results may not correlate with in-service performance.
4. Base Materials for Test Specimens
4.1 A minimum of two and preferably four test specimens shall be used to evaluate the performance of any paint system.
4.2 The surface preparation for the test panels should be that, expected to be done in the field or in-service. The surface preparation shall be the same for all test panels in the test program unless, surface preparation is one of the vari ables to be evaluated. Surface preparation must be essentially identical for ail test panels, as the thoroughness of prepara tion may directly determine the performance life of the applied coating system.
4.3 The test panels should be fabricated from the same material over which the coating is expected to perform in-service. Any of the following surfaces may be used:
4.3.1 Abrasive Blasted Steel Plate--The steel plate shall conform to Specification A 36 or Specification A 283. The minimum thickness shall be `/re in. (1.6 mm). The minimum size shall be 4 by 6 in. (100 by 150 mm). Burrs and sharp projections shall be removed from the edges by filing. The test panels shall be freed of oil by suitable grease-removing solvents in accordance with Methods B, C, or D of Methods D 609. The surface shall be blasted to meet the requirements

The W pieces shall be freed from oil by the use of suitable ^li.removing solvents in accordance with Methods B, C, fp 0f Methods D 609. Those persons desiring to test Ratings over rusty or slightly rusted surfaces (Note 1) should jjjlt to Standard D 2200, select the degree of rusting desired
U0TB i__When testing over rusty surfaces, the test specimens should Aeferably be pre-corroded (weathered) in the same environment in Jvjj, they ultimately will be exposed. The environment in which the."
ij rusted prior to painting has considerable influence on the arfotmance ofpaint applied to such steel. Artificial rusting, however, is Quitted but conditions must be stated in the test report
4.3,3 Cold-Rolled Steel Strip--Cold-rolled steel strip has a j-htiv roughened surface free from mill scale and rust, and jj useful for checking the relative performance of paints on a cjeaD) uniform surface. The steel strip shall conform to one ofthe types described in Methods D 609. The panels shall be not less than 4 by 6 in. (102 by 152 mm) in size and all edges stall be smooth and uniformly rounded. The metal panels stall be prepared by the agreed upon method (A, B, C, or D) ia Methods D 609.
4.4 After surface preparation, the panels shall be prime as soon as possible to prevent flash rusting or deposit
of any foreign contaminant on the cleaned surface. After surface preparation, if the panels are stored prior to coating, precautions must be taken to preserve the clean surface.
5. Printing Test Specimens
J.1 Apply all coatings in strict accordance with the coating manufacturer's written recommendations. The oethod of application expected for the production work on tie job should also be used for test panel application.
52 If the method of application is unknown select one of tie Mowing (Note 2):
Method A--Automatic Spray Machine Method B--Automatic Dip Coater Method C--Manual Spray Application Method D--Motor Driven Blade Applicator Method E--Brush Application Method F--Roller Coating Method G--Curtain Coating
N' 2--Details for the application of paint by Methods A, B, or D
are given in Test Methods D 823.
5.3 Measure and record the film thickness of each coat in accordance with the methods recommended in Test Methods D 1186. If the test panel is covered by rust and mill scale, these methods will be less accurate, as they are influenced by the surface characteristics of this base metal. In such cases, approximations can be made by wet film thickness measure ments in accordance with Methods D 1212, or the amount of paint applied to a known area can be weighed and the average dry film thickness computed. It should be noted that even though dry film thickness measurements in accordance with Test Methods D 1186 are less accurate on surfaces with rust and mill scale than on smooth steel surfaces, they are still more accurate than those obtained by Methods D 1212 or weighing.
5.4 Allow the proper drying time between coats for multiple paint systems and before exposure as required by the coatings manufacturer and include in the test record.
5.5 Paint the back and edges ofall test specimens with the same systems as that being tested on the front of each panel. This painting provides considerable information on the behavior of the paint system on the reverse side.
5.6 The test specimens may be scribed to base metal prior to exposure. Rate any corrosion from this point ofdamage in accordance with Methods D610.
6. Exposure
6.1 The type of exposure and the position of the painted specimens may be selected from the following:
5, facing south 45, facing south 45, facing north
Vertical, feeing south
Vertical, facing north
Insulated (backed or black box) in accordance with Practice G 7.
6.2 Mount the specimens so they do not cast shadows on each other, or contact each other or any metallic material, or any material capable of acting as a wick. Also, mount the specimens so that the products of weathering and rain water drippings do not flow from one to another.
N' 3--A suitable material for the construction of racks and
supports is painted wood. Metal, such as aluminum, is also suitable if the test specimens are properly insulated as by the use of porcelain or suitably selected plastic. .
7. Test Period and Rating of Paints
7.1 The test period shall be sufficient to evaluate the characteristics of the system under consideration.
7.2 Inspect at regular intervals. 7.3 Evaluate (resistance to or) degree of rusting, chalking, checking, cracking, and blistering using the following ASTM photographic reference standards: Test Methods D610, D 659, D 660, D 661, and D 714.

1. Single-Panel Paint Record Form
1.1 The single-panel form2 provides on one sheet the complete exposure record of a paint test panel. It provides a record for a period of 60 months for 15 or more different types of failure. On the front side there are eight graphs upon which the record for practically every type of failure may be plotted. The type of failure is specified on six of the graphs as indicated and there are two additional graphs for special types offailure that may be required. In order to record three types of failure on a single graph the symbols X, O, and (dot) are used. The numerical system of grading is used. Ten indicates perfection or absence of failure while zero repre sents complete failure. Ratings are. plotted along the vertical axis in steps of 2. Intermediate ratings in steps of 1 may be plotted between the lines. Time is plotted along the hori zontal axis. To illustrate the use of the single-panel record form, Fig. 1 shows a section of one graph with gloss, chalking, and erosion ratings recorded.
1.2 On the reverse side of the single-panel form are columns for recording the composition, the reduction proce dure, and miscellaneous information for a paint system for as many as four coats. Ample space is provided for addi tional remarks.

3. Summary of Test Method
3.1 Instruments complying with this test method measure thickness by using a spring calibrated to determine the force required to pull a permanent magnet from a ferrous base coated with a nonmagnetic film. The instrument must be placed directly on the coating surface to take a reading.
1 These test methods are under the jurisdiction of ASTM Committee D-l on Paint and Related Coatings and Materials and are the direct responsibility of Subcommittee DO 1.23 on Physical Properties of Applied Paint Films.

.4. Significance and. Use
4.1 The attractive force of the magnet to the substrate varies inversely with the thickness of the applied film. The spring tension required to overcome the attraction of the magnet to the substrate is shown on the instrument scale as the distance (in mils or micrometres) between the magnet and the substrate.
4.2 The accuracy ofthe measurements may be influenced when made closer than 1 in. (25 mm) to an edge.
5. Apparatus
5.1 Permanent Magnet, small, either attached directly to a coil spring ("pencil" gage)4 or to a horizontal lever arm which is attached to a helical spring ("banana" gage).3 Increasing force is applied to the magnet by extending file coil spring in the first case or turning a graduated dial that coils the helical spring in the second. The readings obtained are shown directly on the instrument scale or converted by reference to a calibration curve.
6. Test Specimens
6.1 When this test method is used in the field, the
specimen is the coated structure or article on which the
thickness is to be evaluated.
6.2 For laboratory use, apply the materials to be tested to
panels ofthe composition and surface conditions on which it
is desired to determine the thickness.

N' 1--Applicable test panel description and surface preparation
methods are given in Methods D 609.
N' 2--Coatings should be applied in accordance with Test
Methods D 823 or as agreed upon between the purchaser and the seller.
7. Calibration of Apparatus
7.1 Calibrate the instrument in an area free of stray magnetic fields, such as power lines, generators, or welding equipment There shall be no vibration apparent on the test piece when the instrument is being calibrated.
7.2 Use a bare section of the substrate after the specified surface preparation method has been accomplished. If an uncoated section of the substrate is not available, uncoated test panels of a similar steel type on which the specified ;, surface preparation has been performed, may be used.

Use nonmagnetic thickness shims for calibration. Id shims are non-precision and, therefore, thickness must ^verified with a micrometer.
3--Other thickness, standards such as National Bureau of Hards certified thickness calibrations standards may be used for the *-hSSw> of the magnetic pull-off gages. The use of these thickness ^Hatds requires a different calibration method as described in
^C-PA2.
74 Select calibration shims in the expected thickness ' to be measured. For example, if a coating is approxiia" w 3 mils (75 pm) in thickness, calibrate the instrument 1 mils. Then check the calibration, using shims of both a ffLer and greater thickness, to determine the thickness range ^ which the instrument will register accurately. 0 7 j Lay a calibration shim on the bare, uncoated substrate d bring the instrument magnet in direct contact with the !!Li. Remove the magnet from the shim by slowly rotating IgdSal scale ring clockwise (for helical spring-type instru ments) or lifting the entire instrument housing (for coil mring-type instruments). Hold the shim so that it will npt to during calibration, causing the magnet to lift premaujely. Observe the thickness shown on the instrument scale at the moment when the magnet breaks contact with the
surface. 7.6 Ifthe instrument scale reading does not agree with the
slant thickness, calibration is required. This can be accom plished by physical calibration or by drafting a calibration curve. A calibration curve involves plotting a graph with the irt,,al gage reading on one axis and the shim reading on the other. For physical calibration, consult the manufacturer's instructions.
N' 4--Instruments based on the scale dial ring/helical spring can
be calibrated and used in any position, while those based on the coil spring must be calibrated and used in the vertical position only.
8. Procedure
8.1 Use the instrument only after it has been calibrated in accordance with Section 7.
8.2 Assure that the coating is dry prior to use of the instrument
8.3 Inspect the magnet tip and surface to be measured to assure that they are clean. Adherent magnetic filings or other surface contaminants will affect gage readings.
8.4 Take readings in areas free of vibration, electrical, or magnetic fields.
8.5 If thickness readings are encountered outside the range of accuracy determined during calibration in 7.4, repeat the calibration procedure in that range. Check the calibration frequently during use to assure that the instru*nt continues to read properly.
8.6 Take a sufficient number of readings to characterize ike sample.
8.6.1 For laboratory measurements, a recommended minum is three for a 3 by 6-in. (75 by 150-mm) panel and oore in proportion to size. . jj-62 For field measurements, a recommended minimum B five determinations at random for every 100 ft2 (10 m2) of, !utrace area. Each of the five determinations should be the can of three separate gage readings within the area of a 'Hn. (12-mm) diameter circle.
8.7 Make measurements at least 1 in. (25 mm) away from any edge or comer of the specimen. If it is necessary to measure closer than 1 in., recheck the calibration in the specific area to determine the extent of the effect (ifany) the edge has on the measurement.
8.8 Report the instrument used, serial number, range, and mean of the thickness readings found.
9. Precision
9.1 An interlaboratory test was conducted to determine the within-laboratory and between-laboratory precision of several types of instruments in measuring a wide range of coating thickness by this method. On the basis of this interlaboratory test, the within-laboratory coefficients of variation and between-laboratory coefficients of variation were found to be those shown in Table 1 for the instruments evaluated. Based upon these coefficients of variation, the following criteria should be used forjudging the acceptability of results at the 95 % confidence level:
9.1.1 Repeatability--Two results by the same operator with the same instrument should be considered suspect if they differ by more than the maximum allowable difference values shown in Table I.
9.1.2 Reproducibility--Two results, each the mean of four measurements, obtained by operators in different laborato ries should be suspect if they differ by more than the maximum allowable difference values shown in Table 1.
TEST METHOD B--MAGNETIC FLUX GAGES
10. Summary of Test Method
10.1 This test method covers instruments that measure coating thickness by changes in the magnetic flux within the instrument probe or the instrument itself. The instrument probe must remain in direct contact with the coating at all times during measurement.
11. Significance and Use
11.1 The magnitude of flux changes is an inverse (nonlinear) function of the distance between the probe and the ferrous substrate.
11.2 The accuracy of the measurements may be influ enced when made closer than 1 in. (25 mm) to an edge or 3 in. (75 mm) to another mass of steel. The edge or mass of steel may cause flux leakage from the instrument, thus distorting the readings.
12. Apparatus
12.1 The testing apparatus shall be mechanically or elec trically operated. The mechanically operated instruments house an integral horseshoe magnet, the contacts of which are placed directly on the coated substrate.6 The electrically operated instruments utilize a separate instrument probe that houses the magnet and must be placed directly on the surface.7 In both types, the coating thickness is shown on the instrument scale or meter.
`Apparatus of the mechanical type found to be suitable for this purpose includes Elcometer 101.
7 Apparatus ofthe probe type found to be suitable for this purpose indudes the Minitest, Minitector, Verimeter, GE Gage, Perroascope, and Accuderm.

Standard Test Method for Viscosity by Ford Viscosity Cup1
This standard is issued under the fixed designation D 1200; the number immediately fallowing the designation indicates the year of original adoption or, in the case of revision, the year oflast revision. A number in parentheses indicates the year oflast reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.
This standard has been approvedfar use by agencies ofthe Department of Defense to replace Method 4282 ofFederal Test Method StandardNo. 141. Consult the DoD Index ofSpecifications and Standardsforthe specific year ofissue which has been adopted by the Department ofDefense.
1; Scope 1.1 This test method covers the determination of the
viscosity of Newtonian or near-Newtonian paints, varnishes, lacquers, and related liquid materials with the Ford-type efflux viscosity cup. If the material is non-Newtonian, that is, shear-thinning or thixotropic, Test Method D2196 should be used.
1.2 This standard may involve hazardous materials, opera ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Newtonian Materials by Rotational (Brookfield) Viscometer12 E 1 Specification for ASTM Thermometers3
3. Terminology
3.1 Definitions: 3.1.1 Newtonian liquid--a liquid in which the viscosity is independent of the shear stress or shear rate. If the ratio of shear stress to shear rate is not constant, the liquid is non-Newtonian. 3.1.2 Near-Newtonian liquid--a liquid in which the vari ation of viscosity with shear rate is small and the effect on viscosity of mechanical disturbances such as stirring is negligible.
4. Summary of Test Method
4.1 The Ford viscosity cup is filled level full with the liquid under test, and the time for the material to flow through one of the standard orifices is measured.
5. Significance and Use
5.1 This test method is useful for the determination of package and application viscosities of a number of paints
pd other coatings and in the thinning ofthese materials, but is limited to Newtonian or near-Newtonian liquids.
5.2 There are other types of apparatus for measuring viscosity in the laboratory that produce more accurate results.
6. Apparatus
6.1 Ford Viscosity Cups--Nos. 1, 2, 3, 4, and 5 Ford viscosity cups made of corrosion- and solvent-resistant materials assembled as complete units (Note 1), and con forming to the dimensional requirements shown in Fig. 1. The orifice dimensions are considered as a guide only as the combination of cup and orifice dimensions must permit conformance to the flow formula for each cup as listed in the Appendix.
N' 1--If the orifice is removed from the cup for any reason the
cup should be recalibrated before use as described in the Appendix.
6.2 Thermometer--Saybolt Viscosity Thermometer con forming to the requirements for Thermometer 17C (19 to 27CC) or 17F (66 to 80"F) as prescribed in Specification E I.
6.3 Timing Device--Any timing device may be used providing that the readings can be taken with a discrimina tion of 0.2 s or better.
7. Test Specimen
7.1 The specimen of the material to be tested shall be visibly homogeneous and free of any foreign material or air bubbles.
8. Temperature of Testing
8.1 All measurements with the Ford viscosity cups shall; be made at 77F (25<'C) or a temperature agreed upoa| between producer and user. Temperature drift during the test* should be kept to a minimum and should not exceed 0.4F (0.2*Q.
N' 2-- It is impossible to predict the effect oftemperature change|
on each material with which the apparatus may he used. This factor may s be less than 1 % per degree Celsius for some liquids whereas others may 1 be as high as 8 to 10 % per degree Celsius.

jl. procedure tl.l Make viscosity determinations in a room free of
drafts and rapid changes in temperature. For the highest degree of precision the room temperature should be between 72 and 82F (22 and 28C). Determinations should be made jt a temperature above the dew point of the atmosphere surrounding the apparatus.
11.2 Choose the proper cup so that the time of efflux will be between 20 and 100 s (preferably between 30 and 100 s)
for cup Nos. 3, 4, and 5; between 55 and 100 s for cup No. 1;
and between 40 and 100 s for cup No. 2 (Fig. 2). 11.3 Level the instrument so that a cup may be filled level
full without a meniscus or overflow at one side. 11.4 Determine the time in seconds of efflux as follows:
Close the orifice, for example, by holding a rubber stopper against it. Fill the cup with the prepared specimen. The preferred method is to overfill the cup and scrape off the excess with a straightedge. Pull the stopper away and
simultaneously start the timing device. Measure the time until the first break in the stream.
11.5 Measure the temperature of the fluid in the efflux stream.
11.6 If the cup has been established to be nonstandard when calibrated as described in the Appendix, apply the percent difference to the measured seconds to get the corrected viscosity in Ford-cup seconds.
12. Care of Cup
12.1 Following each determination, clean the cup by the use of a suitable solvent and a soft brush. Under no conditions should metal cleaning tools be brought into contact with the instrument. Particular care must be exer cised in cleaning the orifice to avoid any film deposit or nicks on the inside walls.
13. Report
13.1 Report the following information: 13.1.1 The efflux time to the nearest 0.2 s for the cup orifice combination (for example, viscosity 33.2 s with No. 4 Ford- cup), the temperature of the test specimen (as in the efflux stream), and the immediate history of agitation and rest prior to the measurement.

APPENDIX
XI. Calibration Procedure for Ford Caps
XI.1 The orifice of the Ford cup is commonly made of brass or some other corrosion-resistant material which is subject to wear with use and cleaning. A small change in diameter of the orifice becomes significant in the results obtained with the use of this type of viscosity-measuring apparatus.
X1.2 The viscosity standards4 are available only as 1-pt samples.
XI.3 Select the appropriate liquid viscosity standard for the cup to be calibrated (see Table Xl.l). Bring this cup and the liquid viscosity standard to a constant temperature as close as possible to 77.0'F (25.0C) or to the operating temperature of the cup. Determine the time of efflux to the nearest 0.2 s using the procedure detailed in Section 11. Keep the temperature drift to within 0.4F (0.2"C). If the temperature is not 77F, the actual temperature must be noted and the viscosity of the standard oil corrected to this temperature.
XI.4 The following formulas are used to convert the time of flow in seconds, t, to kinematic viscosity V:
4 Certified kinematic viscosity standards are available from the Cannon Instrument Co., P-O. Box 16, State College, Pa. 16801. For particular oils applicable for use with the Ford Cups referto Table Xl.l. Oils available from other sources, having known kinematic viscosities, may also be used.
V, = 0.49 (1 - 35.0) V2 = 1.44 (t - 18.0) V3 = 2.31 (t - 6.58)
V4 = 3.85 (t - 4.49)

XI.5 The difference between the certified viscosity and the determined viscosity, multiplied by 100 and divided by the certified viscosity, will give the percent variation of the cup from standard. A percent correction can be applied to the seconds flow when the cup is in normal use. If the qip varies more than 10 % from standard, it is recommended that the orifice be replaced and that the cup be recalibrated.

3. Significance and Use
3.1 The property of color of a solvent varies in impor tance with the application for which it is intended, the amount of color that can be tolerated being dependent on the color characteristics of the material in which it is used. The paint, varnish, and lacquer solvents, or diluents com mercially available on today's market normally have little or no color. The presence or absence of color in such material is an indication of the degree of refinement to which the solvent has been subjected or of the cleanliness of the shipping or storage container in which it is handled, or both.
3.2 For a number of years the term "water-white" was considered sufficient as a measurement of solvent color. Several expressions for defining "water-white" gradually appeared and it became evident that a more precise color standard was needed. This was accomplished in 1952 with the adoption of Test Method D 1209 using the platinumcobalt stale. This test method is similar to the description given in Standard Methods for the Examination of Water and Waste Water7 and is referred to by many as "APHA Color." The preparation of these platinum-cobalt color standards was originally described by A. Hazen in the American Chemical JoumaP in which he assigned the number 5 (parts per ten thousand) to his platinum-cobalt stock solution. Subsequently, in their first edition (1905) of Standard Methods for the Examination of Water, the American Public Health Association, using exactly the same concentration of reagents, assigned the color designation 500 (parts per million) which is the' same ratio. The parts per million nomenclature is not used since color is not referred directly to a weight relationship. It is therefore recommended that the incorrect term "Hazen Color" should not be used. Also, because it refers primarily to water, the term "APHA Color" is undesirable. The recommended nomenclature for referring to the color of organic liquids is "Platinum-Cobalt Color, Test Method D 1209."
3.3 The petroleum industry uses the Saybolt colorimeter Test Method, D 156 for measuring and defining the color of hydrocarbon solvents; however, this system of color mea surement is not commonly employed outside of the petro-

ieum industry. It has been reported by various sources that a Saybolt color of +25 is equivalent to 25 in the platinumcobalt system or to colors produced by masses of potassium dichromate ranging between 4.8 and 5.6 mg dissolved in 1 L of distilled water. Because of the differences in the spectral characteristics of the several color systems being compared and the subjective manner in which the measurements are made, exact equivalencies are difficult to obtain.
4. Apparatus
4.1 Spectrophotometer, equipped for liquid samples and for measurements in the visible region.9
N' 2--The spectrophotometer used must be clean and in fust-
class operating condition. The instrument should be calibrated in accordance with the instructions given in the Standards for Checking the Calibration of Spectrophotometers (200 to 1000 nm).10
4.2 Spectrophotometer Cells, matched having a 10-mm light path.
4.3 Color Comparison Tubes--Matched 100-mL, tailform Nessler tubes, provided with ground-on, optically clear, glass caps. Tubes should be selected so that die height of the 100-mL graduation mark is 275 to 295 mm above the bottom of the tube.
4.4 Color Comparator--A color comparator constructed to permit visual comparison of light transmitted through tail-form, 100-mL Nessler tubes in the direction of their longitudinal axes. The comparator should be constructed so that white light is passed through or reflected off a white glass plate and directed with equal intensity through the tubes, and should be shielded so that no light enters the tubes from the side.11
5. Reagents
5.1 Purity ofReagents--Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chem ical Society, where such specifications are available.12 Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination.
5.2 Purity of Water--Unless otherwise indicated, refer ences to water shall be understood to mean reagent water

10. Precision15
10.1 Color Standards: 10.1.1 These precision statements are based upon an interlaboratory study in which five platinum-cobalt stand ards having values of 25, 75, 170, 385, and 475 were prepared in accordance with the instructions given in Section 7 of this test method and were given coded labels. These solutions were tested by one analyst in each of ten different laboratories making a single observation on one day and then repeating the observation on a second day. The analysts were requested to estimate the color to the nearest one unit for solutions below 40 platinum-cobalt, to the nearest five units for solutions between 40 and 100 platinum-cobalt and to the nearest ten units for solutions above 100 platinum-
cobalt. In this interlaboratory study, the within-Iaboratory coefficient of variation was found to be 1.8 % with 60
degrees of freedom, and the between-laboratories coefficient of variation was found to be 5.3 % with 54 degrees of freedom. Based on these results, the following criteria, calculated in accordance with Practice E 180, should be used forjudging the acceptability of results at the 95 % confidence level when the results are obtained under optimum condi tions where the hue of the sample matches exactly the hue of the standards. Poorer precision will be obtained in varying degrees as the hue of the sample departs from that of the standards.
10.1.1.1 Repeatability--Two results, obtained by the same analyst on different days, should be considered suspect if they differ by more than 5.1 %.
10.1.1.2 Reproducibility--Two results, obtained by ana lysts in different laboratories, should be considered suspect if they difFer by more than 15 %.
10.2 Specimen:16 10.2.1 In an interlaboratory study of this test method in which the standards described in Table 3 were used, the within-Iaboratory standard deviation was found to be one platinum-cobalt unit at 56 degrees of freedom and the between-laboratory standard deviation was found to be 2 platinum-cobalt units' at 25 degrees of freedom. Based on these standard deviations, the following criteria should be used for judging, at the 95 % confidence level, the accept ability of results obtained on light colored samples. 10.2.1.1 Repeatability--Two results, each the mean of duplicates, obtained by the same operator on different days should be considered suspect if they difFer by more than two platinum-cobalt units. 10.2.1.2 Reproducibility--Two results, each the mean of duplicates, obtained by operators in different laboratories should be considered suspect if they differ by more than seven platinum-cobalt units.

Standard Test Method for Fineness of Dispersion of Pigment-Vehicle Systems1
This standard is issued under the fixed designation D 1210; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year oflast revision. A number in parentheses indicates the year of last reapproval, A superscript epsilon (<) indicates an editorial change since the last revision or reapproval. This test method has been approvedfor use by agencies ofthe Department ofDefense. Consult the DoD Index ofSpecifications and Standardsfor the specific year ofissue which has been adopted by the Department ofDefense.
41 N' --Editorial changes were made throughout in June 1988.
1. Scope 1.1 This test method covers measurement ofthe degree of
dispersion (commonly referred to as "fineness of grind") of the pigment in a pigment-vehicle system such as liquid coatings and their intermediates. It may also be used to assess the inclusion of particulates by a cleanliness rating.
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish, appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.
2. Summary of Test Method
2.1 The product is spread by means of a scraper in a calibrated tapered path. At some point in this path, particles or agglomerates, or both, will become visible. A direct reading from the calibrated scale is then made at the point where the particles form a definite pattern. When the single path gage is used it is also possible to rate "cleanliness" (see 6.2).
3. Significance and Use
3.1 In making pigmented products, the pigment is usually dispersed in a portion of the vehicle in some sort of mill. At this stage, it is necessary to be able to judge if the pigment agglomerates have been sufficiently broken up so as not to interfere with the smoothness of the finished coating film. This test method describes a way of making this judgment
4. Apparatus 4.1 Gage--A hardened steel, stainless steel, or chrome-
plated steel block (Fig. 1) approximately 6.7 in. (170 mm) in length, and 0.6 in. (15 mm) in thickness. The top surface of. the block shall be ground smooth and planar and shall contain one or two paths 5 in. (127 mm) in calibrated length. The path shall be tapered uniformly in depth lengthwise from 100 pm (about 4 mils) at 10 mm from one end to zero depth at the other with intermediate calibrations in accord ance with the depth at those points. Preferred calibrations are

Hegman units and micrometres (Note 1). Two path widths are covered by this test method:
4.1.1 Two parallel paths each 0.5 in. wide (12.5 mm) and
spaced 0.5 in. apart centered in a block 2.5 in. (65 mm) wide. 4.1.2 One path 2 in. (50 mm) in width centered in a block
3.5 in. (90 mm) wide.
N' t--Several arbitrary scales and modifications of the gage are
used by industry. In order that readings obtained with these arbitrary scales and modifications can be reported in the preferred units, the approximate relationship of these scales to gage depth is shown in the following example:

5. Care of Gage
5.1 Clean the gage immediately after each use. Use solvent and a soft cloth. Keep the gage covered or encased all times when not in use. Protect gages that lie idle f extended periods of time from rust with an oil coating or soaked wrap.
5.2 Do not allow any hard materials to come in with the gage surface or scraper in any manner that result in scarring or nicking. Avoid tapping or serai with other metal.
5.3 The scraper may be rendered unsatisfactory for use wear or nicks of the contact edge or warpage (Note Replace or recondition unsatisfactory blades.

7.2 Hand stir the specimen (Note 3) vigorously for 2 min, taking care that air bubbles are not whipped into the paint. To be sure of an accurate grind reading, specimens must be free of air bubbles.
N
' 3--For this test method to function properly, the pigment
particles in the specimens to be tested should be free to settle to the bottom of the gage channel after the drawdown. Therefore, before testing, high-viscosity intermediate specimens that have little ability to flow should be reduced with a compatible liquid. Reduction should be in approximately the same proportion as the intermediate will be reduced

7.4.2 Observe the point where the material first shows a definite speckled pattern, not just isolated specks (see Figs. 3 ffld 4). This is the fineness reading. When using the two-path Pge, average the values id the two paths to the nearest JA Htgman unit. This average is considered one reading.
7.5 After the first drawdown and reading, which are Preliminary for establishing proper test conditions and loBting die position of the fineness reading, repeat the Procedure twice, beginning with 7.3, to obtain two test ^ngs. This process allows the two test readings to be ade with limited time lapses between completion of "Gwdown and reading. (Do not consider any reading for the

3. Description of Terms Specific to This Standard
3.1 True cold-checks on solid wood show as one or more straight cracks on the applied film. Cold-checks manifest themselves in either of two ways:
3.1.1 Long continuous wavy lines with the grain or at various directions at angles that can be perpendicular to the direction of the grain.
3.1.2 Innumerable fine lines erratic in direction an<F length forming a network over a portion or all of the panel. This effect may be likened to crazing of the lacquer film.
3.1.3 On plywood the direction of the cracks will oflen vary because of the stresses set up by other than the top stratum. Therefore, all checks may be considered as failures, and appropriate notations on the character of the cracks must be made to assist in the interpretation. While it is recognized that cracks in the substrate may occur (veneer checking), failures observed in the lacquer coating may be due to action of moisture (humidity) or of cold, or both. Checking caused by moisture appears along the grain and is characterized by short cracks (usually not more than `/z in. (13 mm) in length) occurring either singly or in clusters. These lines or clusters may progress along the grain in a discontinuous fashion. Should either veneer checking or

moisture checking be observed, the test should be discon tinued, and rerun.
3.2 The checks may be perceptible only by visual observa tion of the panels at an angle, under a strong light, or the cracks may be wide enough to be readily discernible in direct daylight.
4. Summary of Test Method
4.1 Lacquer-coated wood panels are subjected first to a high temperature, followed by an exposure to low tempera ture, and then a return to room temperature for given periods of time, which constitutes one cycle. The method does not define the number of cycles which a lacquer must withstand, this condition being a requirement which must be agreed upon by the purchaser and the seller.
5.. Significance and Use
5.1 A common type of failure of clear films applied to wood is cracking or checking that may occur over a period of time either with the grain or at an angle. This cold check test is designed to accelerate, the appearance of checks or cracks by cycling the temperature;
N' 1--Except when elaborate precautions are taken to control the
moisture content.of the wood:before and after finishing and during the test, failures may quite often occur as a result ofdimensional changes in the wood due to moisture change rather than temperature change.
6. Apparatus
6.1 Refrigerator (Dry Ice)--The refrigerator should be a well-insulated box, cooled by air which has been circulated over solid carbon dioxide (dry ice). The air must strike the panels indirectly after passing over the solid carbon dioxide. The unit shall have a capacity and temperature control sufficient to cool the test panels in accordance with the requirements prescribed in Section 9.
6.2 Mechanical Refrigerator--As a less desirable alterna tive, a well-insulated mechanical refrigerator may be used having sufficient capacity to cool the test panels in accord ance with the requirements prescribed in Section 9. The refrigerator should have some means for providing ait circulation. It should be understood that results obtained with a mechanical refrigerator may not correspond to results obtained with a "dry ice" refrigerator. Consequently the type of unit employed shall be stated in the report.
6.3 Oven--The oven shall be electrically heated and of any standard type capable of being automatically controlled and of sufficient capacity to heat the panels under test to 1$ 5'F (49 3C) within 1 h. A circulating fan shall 1* installed in the oven.

7. Test Panels
7.1 Unless otherwise agreed, the test panel shall be cut from synthetic resin-bonded, five-ply plywood with feces and backs made with straight-grain walnut veneer having no sizing or other surface pretreatment. The dimensions of the test panel shall be 6 by 12 in. (152 by 305 mm), and approximately u in. (8 mm) thick.
7.2 Solid wood, heavier or lighter veneers, or other species
of wood may be agreed upon by the purchaser and the seller. Type of wood and panel size should be clearly defined in the
report. 7.3 The wood selected shall have a moisture content of
not less than 6.0 % and not more than 8.0 % at the time of testing. The moisture content of the wood may be deter
mined by an electric moisture gage or in accordance with Methods D 805.
7.4 Panels may be conditioned to a moisture content of 7 to 8 % under any of the following conditions:4
Temperature, F
Relative Humidity, %
65 to 75 90 to 100 120 to 125
35 to 40 40 to 45 45 to 50
8. Preparation of Panels
8.1 Five-Ply Plywood (With faces and backs made with straight-grain, closed face walnut veneer having no sizing or other surface pretreatment) shall be prepared as follows:
8.1.1 Sand panels until smooth with No. 240 sandpaper, or equivalent.
8.1.2 Fill with representative walnut wood paste filler and allow to dry for 24 h at not less than 70 nor more than 80F.
8.1.3 Spray a sufficient number of coats of about equal thickness of the test lacquer on the panel within an 8-h period to give a total dry film thickness of 3 0.5 mil (75 13 tun). Allow a minimum period of 2 h between coats. Do not edge or back the panel with any protective coating.
8.1.4 To minimize the effects of variations in the wood, apply a control lacquer of known performance to a portion of each panel in the same manner as the test lacquer. After aging, the panels may be cut (Note 2) into sections finished only with one lacquer, but each section should conform to the description given in Section 6.
N' 2--Cutting of panel is optional and may be contingent upon
the size and capacity of the test equipment
8.1.5 The thickness of films applied to panels may be determined with reasonable accuracy by placing a metal panel adjacent to the wood panel being prepared and measuring the film thickness on the metal panel with a magnetic thickness gage. The plywood panel must be sanded and rubbed before testing and the use of waxes or oils should be closely regulated since these can make a difference in the results obtained. For sanding and rubbing procedure, see Practice D2571.
8.2 Panels of Five-Ply Plywood with Walnut Veneer for Complete Lacquer System--Proceed as agreed upon by the Purchaser and the seller.
1 These conditions were taken from the curve on p. 191 of the Wood Handbook, Forest Products Laboratory, Madison, WI.
8.3 Panels ofSolid Wood, Lighter or Heavier Veneers, or Other Species of Wood--Proceed as agreed upon by the purchaser and the seller.
8.4 General Treatment--Except where specific agree ments exist between the purchaser and the seller, all panels shall be subjected to the following treatment:
8.4.1 Prepare at least three panels for each lacquer or lacquer system and each other variable, such as type of panel, that may be under test.
8.4.2 Air-dry overnight.
8.4.3 Age finished test panels for ten days under condi tions that will maintain a moisture content of 6 to 8 %.
9. Procedure
9.1 Place a predetermined number of panels, depending on the capacity of the oven and refrigerator, vertically in racks so that air can pass between all panels. The lacquered sides of the panels shall not face the walls of the heating or cooling units. Place the racks for 1 h in an oven at 120 5F (48.9 3C) in such a manner as to avoid localized overheating. At the expiration of this period, transfer the panels within 1 min to a refrigerating unit maintained at --5 2F (-21 1C) (unless special conditions indicate some other agreement between the purchaser and the seller). The number of panels shall be such that the time required to reach this temperature is not less than 30 min and not more than 45 min. The temperature can be measured by a thermocouple imbedded in the panel just underneath the film.
9.2 Remove the panels from the refrigerator after 1 h exposure. After allowing 15 min relaxation period, inspect the panels under a strong light. Best results will be obtained if the light source is directed from behind and over the shoulder of the observer. Circle checks with crayon, since they will often heal or at least appear to heal and become relatively invisible. Once the capacity of any given ovenrefrigerator combination (number of panels that will permit specified rates of heating and cooling) has been determined, make all subsequent tests with this number of panels using dummy panels where necessary. If this precaution is not followed, rates of cooling and heating will differ each time the test is run, and reproducibility will suffer.
9.3 The period of 1 h at 120F (49C) followed by 1 h at -5F (-21C) and 30 min at room temperature (15 min relaxation period, 15 min to allow for inspection), constitutes one cycle. Repeat this cycle until failure occurs or until a prescribed minimum number of cycles has been obtained.
9.4 The failure end point is defined as the cycles on which innumerable fine lines appear as described in Section 3 or on which a total of four checks (1 to 2 in. (25 to 50 mm) in length) or two checks (more than 2 in. (50 mm) in length) appear in the film. Exclude the outer `/2-in. (13 mm) perimeter of panel when examining for failure (cracks).
9.5 Unless a laboratory operates on three shifts there will be a relaxation period every night and over week ends. The report should show when these rest periods occurred.
10. Report
10.1 Report the following information: 10.1.1 Type of construction, variety, and size of wood panels used, for example, 5-ply, Vie-in. (8-mm) walnut

ical, 10.1.3 Finishing system and schedule of application, and 10.1.4 Number of cycles passed without failure and note
of all wood failures, specifying the cycle on which such failures occurred.
11. Precision
11.1 Results on all three panels should fall within 2 cycles of the mean of all three panels. If this does not occur, additional panels shall be run until there are at least three panels which fall within this range. All panels that have been run are to be taken into consideration. This requirement also applies to panels finished with the control lacquer. Precision as stated here applies only to the test panels described in Section 7.

This standard is issued under the fixed designation D 1212; the number immediately following the designation indicates the year of original adoption or, in the case ofrevision, the year oflast revision. A number in parentheses indicates the year of last reapprovai. A superscript epsilon () indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish, and lacquer. Two methods are described as follows:
1.1.1 In Test Method A, the Wet Film Thickness Gage (English or Metric graduation (see 5.1)) is used to measure wet film thicknesses up to 60 mils on the English scale series, and up to 700 pm on the metric scale series (Sections 5 through 8).
1.1.2 In Test Method B, the Pfund Gage is used to measure wet film thicknesses up to 14.2 mils (360 pm) (Sections 9 through 13).
1.2 This standard does not purport to address ifany, the safety problems associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

3. Summary of Test Methods
3.1 The material is applied in the laboratory to plane, rigid test panels or in the field to the surface being coated. The wet film thickness is determined as quickly as possible to reduce shrinkage due to solvent loss.
3.2 In Test Method A, a gage with one eccentric and two concentric wheels is rolled over the surface and the point where the eccentric wheel first touches the wet film is determined.
3.3 In Test Method B, a gage with a convex lower surface is pushed into the wet film until the center touches the substrate. The diameter of the spot of wet coating left on the convex surface is measured and the film thickness calculated from the diameter of the spot and the radius of curvature.
4. Significance and Use
4.1 Wet film thickness measurements aid in the predic tion of dry film thickness. In instances where dry film thickness cannot be measured nondestructively, wet film thickness frequently specified. Also, the ability to deter

mine wet film thickness during application can provide the opportunity to correct the application procedures.
5. Apparatus
. TEST METHOD A
5.1 Wet Film Thickness Gage3--Two versions ofthe gage are now in use4: The original design as shown in Fig. 1 and a later design as shown in Fig. 2. Both designs consists of an eccentric center wheel supported by two concentric wheels so as to provide two scales that are bilaterally symmetrical. As the gage is rolled on the film, there is a change in clearance between the wet film and the eccentric wheel. The point at which the film first touches the center wheel measures the thickness of the film.
5.2 The later design shown in Fig. 2, moves the eccentric wheel from between the concentric wheels, as shown in Fig. 1, to the outside of the gage and closer to one of the concentric wheels. Gage reading errors of parallax across the gage are eliminated as the two scales are placed directly on the eccentric wheel and' errors when measuring on uneven support surfaces are reduced by placing the eccentric wheel closer to one of the supporting concentric wheels.
5.3 Best precision is obtained when using the near linear central portion of each scale, constituting about 80 % of its total fringe as shown in the diagram in Figs. 1 and 2. Therefore, the range of the particular gage selected for use should be such that the measured film thickness falls within, and preferably toward the center of the middle 80 % of each scale. Gages are available covering the following ranges in mils and microns;

TEST METHOD B
9. Apparatus 9.1 Pfund Gage3--The gage6 shown in Fig. 3 consists of a
convex lens L with lower surface having a radius of curvature of 250 mm mounted in a short tube Tu that slides freely in an outer tube T2. The compression springs S keep the convex surface out of contact with the wet film until pressure is applied to die top of T,, forcing the lens L down through the film. The displaced material forms an oversized circular spot of diameter D, on the convex lens (larger than the diameter D corresponding to the thickness T of the film) because of the meniscus effect due to wetting and surface tension effects on the glass lens.
9.2 Steel Scale (furnished with Pfund Gage), calibrated in millimetres.
10. Procedure 10.1 Apply the material to suitable plane, rigid panels of
6 Keinrath, G., "Sphere Penetration Gage," National Institute ofStandards and Technology Circular, NIST, Nat No. 585, Section 1.06, p. 4.
area sufficiently large to permit film thickness measurements at least 1 in, (25 mm), from any edge. Determine the film thickness immediately after application.
10.2 Support the test panels on a suitable flat level base in such a way that there will be no movement or spring of the panels during the film thickness measurements. As shown in the second diagram in Fig. 3, place the gage on the coated surface and slowly force the inner tube down as far as it will go (point F on surface AB of the base) allowing displaced material to escape through the notches in the outer tube but preventing lateral motion of the gage. Upon releasing the pressure, an oversized circular spot is retained on the lens. Its diameter D is the length of the line EG and corresponds to the sum of. two thicknesses: AK = BC = thickness of underlying undisturbed coating: and KE = CG = thickness of overlying displaced coating.
10.3 Remove the gage from the surface, measure to the nearest 0,5 mm in two directions at approximate right angles the diameter of the oversize spot on the lens using the steel scale, and determine the mean of the two measurements that is considered as one reading. Make at least two separate tests to obtain the grand mean film thickness.
10.4 Although this procedure refers to measurements on flat test panels, the same technique may be used in the field or shop on commercial articles, provided the substrate is not distorted at the point of contact to an extent that would affect the measurements.
10.5 If coarse particles in the wet film prevent the lens from making contact with the base at the point F, the results will not be valid.
11. Calculation
11.1 The relations between the diameter of the oversized spot on the lens in millimetres, the approximate thickness of the undisturbed wet film, and the coverage in square feet per gallon are given in a printed table supplied with the Pfund gage. It has been found that empirical equations give approximate values for the wet film thickness, t, as follows:
t (in mils) - (D2 x 1000)/16J? x 25.4 = 0.0943 D2 t (in micrometres) = (D2 X 1000)/16R = 0.25 &
where: D = diameter of spot, mm, and R = radius of curvature of convex lens (250 mm), based on the fundamental assumption that t is exactly one half of the total thickness of the film at the diameter D, as shown in the second diagram in Fig. 3.
11.2 The Pfund gage cannot be calibrated by the manu facturer prior to delivery. For the best results, a correction factor must be established for each type and thickness of material, based on freshly prepared films of known wet film thickness, as measured by Test Method A (Interchemical Wet Film Thickness Gage).
12. Report
12.1 Report the mean of at least two separate readings as the wet film thickness.

within-laboratory standard deviation was found to be 0.21 mil with 30 df and the between-laboratories standard devia tion with 24 df 0.285 mil for two measurements and 0.265 mil for four measurements. Based on these standard devia tions, the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
13.1.1 Repeatability--Results, which are the mean of the two measurements at right angles, obtained by the same operator should be considered suspect if they differ by more
than 0.6 mil for two determinations and 0.8 mil for four determinations.
13.1.2 Reproducibility--Two results, each the mean of two separate determinations, obtained by operators in dif ferent laboratories, should be considered suspect if they differ by more than 0.85 miL

Each time the can of paint is removed from the oven give it one sharp "spank" on the table top. The spank consists of a short rapid jar of the bottom of the can of paint against the top of the table. The violence ofthe jar is such that if the bottom of the can of paint were spanked against the platform of a scale instead of a table top the scale would register approximately 5 lb (2.27 kg) weight. 5.2 At the completion of the exposure, allow the paint to cool at room temperature for 4 h and determine the degree of settling in accordance with Method D 869.

Standard Test Method for Fineness of Grind of Printing Inks By the NPIRI Grindometer1
This standard is issued under the fixed designation D 1316; the number immediately following the designation indicates the year of original adoption or, in the ease of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<) indicates an editorial change since the last revision or reapproval.
j. Scope
1.1 This test method describes the procedure for deter mining the fineness of grind of printing inks using a NPIRI grindometer. It evaluates the size of the largest particles in a finished dispersion but not average particle size or concen tration of sizes.
1.2 This test method is applicable to any dispersion that is fine enough to fall within the 0-25 pm range of the specified grind gage. With a minor variation in procedure, it is applicable to both paste (nonvolatile) and liquid (volatile)
inks. ,
^,
N' 1--The 0-25 pm gage specified in this test method is similar in
principle to the 0-100 pm Hegman gage described in Test Method
D 1210. Sieve analysis for concentration of particles above 45 pm is
covered in Test Method D 185.
1.3 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish' appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

oversize particles that are not hard enough or of the proper size to produce scratches.
4. Summary of Test Method
4.1 This test method utilizes a grind gage having two precision machined grooves each 1 in. (25.4 mm) wide and with a 0-1 mil (0-25 pm) taper. The test specimen is drawn down the paths slowly if a nonvolatile (paste) ink, briskly if a volatile (liquid) ink. The drawdowns are examined for the scale readings at which four and ten scratches appear and at which a preponderance of speckles disappear. The mean of readings from four paths constitutes a single determination.
5. Significance and Use
5.1 Oversize particles in a printing ink may damage a printing plate and adversely affect the appearance of printed ink films. Fineness of grind measurements are useful for deciding when to stop the dispersion process and for deter mining if the test material meets specifications as agreed upon between the supplier and the customer.
5.2 Speckle endpoints identify the size of the largest particles in a finished printing ink. They provide a better measure of overall dispersion quality than do scratch endpoints but, while their single-operator precision is better, their between-laboratory precision is far poorer.
5.3 Scratch endpoints indicate the size and relative number of the coarsest hard particles in a finished printing ink. They provide a measure of grittiness; the higher the 4-scratch endpoint, the grittier the ink; the smaller the difference between the 4- and 10-scratch endpoints, the larger the number of gritty particles in this range. Scratch endpoints may, however, miss gritty particles that ride in the bank ahead of the scraper; for this reason, they are not recommended for premixes or other dispersions containing a preponderance of gritty particles.

7.1 Rags or Tissues, lint- and metal-free. 7.2 Solvent, naphtha or other as appropriate for the ink under test
8. Care of Gage and Blade
8.1 Cleanliness--The scraper and the block must he,
perfectly clean prior to a drawdown. Any dirt or lint present
may produce a scratch and give a false reading
s' Misuse--The grindometer is a precision instrument
and must be treated as such. Do not let any hard materials
contact the gage surface or scraper in any manner thapmight
result in scarring or nicking. Avoid tapping or scratching
with other metal. Use only soft metal-free cloths for cleanup.
8.3 Normal Wear--Under steady usage over an extended
period oftime, both scraper and block will wear but idealized,
scraper wear is much more rapid than block wear. Periodi
cally check the blade as follows:
;
8.3.1 Method 1--Place a small quantity of'an ink across
one end of a flat glass plate and make a drawdown. A
uniform drawdown indicates that the particular scraper edge
is in good condition. A streak of ink or a heavier film of ink
at the places corresponding to the shoulders of the
7A second scraper should be procured for use while the first scraper is being reconditioned or is otherwise out of commission.
grindometer is evidence of blade damage or excessive wear. Repeat the drawdown with the other edge of the blade.
8.3.2 Method 2 (from Test Method D 1210)--Face one edge ofthe scraper down across the bottom ofthe top surface of the grindometer or Other smooth level surface. Place a strong light behind the scraper and examine the contact edge; any light coming through shows that the blade edge has been damaged and is not satisfactory for use. Wear and warpage can also be detected by rocking the blade back and forth. Repeat the procedure on the other edge of the blade.
8.4 Rusting--The grindometer is made of carbon steel and is subject to rusting. Apply a coating of grease or other rust-preventative and keep covered or encased when not in use.
N' 2: Caution--Do not use a gage or blade that exhibits damage or
wear (see 8.2. to. 8.4). Replace or return to the manufacturer for reconditioning. ;
9. Sampling '
9.1 Approximately 2 to 3 mL of ink sample is sufficient to fill four paths of the grindometer. When taking samples either from a container or from a disperser, push aside the top layer and take the sample from below. This technique prevents skin or surface dust from Being transferred to the '
gage. 9.2 If the sample, is a liquid ink, hand stir the sample
vigorously for 2 min, taking care that air bubbles are not " whipped in.
10. Procedure
10.1 Place the gage on a flat, non-slippery surface so that,
the deep end of the grooves is farthest from the operator."
Wipe clean immediately before the test. Be sure die gage
surface is dry and free of lint and wipe marks.
10.2 Using the ink knife, transfer a small quantity ofink
across the deep end of both grooves about Vi in. (12.5 mm)
from the end of the block. Alternatively, different inks may
be placed in the two respective paths.
. 3 ,
10.3 Grasp the scraper in both hands and, holding in a 1
vertical position, place it behind the ink of the gage. Apply
adequate pressure to ensure positive, contact of the bl^derj
with the surface ofthe gage and chaw the ink down the length 1
of the path. Ink remaining on the shoulders is evidence bfj|
insufficient,pressure. '
10.3.1 Paste Inks--Makfe the drawdown with`a smopijl
steady stroke tha^ takes 7 to 10 s to complete.
10.3.2 Liquid Inks--Make the drawdown with a
stroke that takes .1 to 2 s to complete. When testing i
inks, it is essential to work quickly, as partial drying ofl
ink specimen or the ink film can influence test results.`.T
10.4 Set the blade on a sheet of scrap paper, and ihlnt
ately pick up the gage to read the endpoints. Rotate th<
in a light until the patterns, when viewed from the si<j
clearly visible. Record endpoints (see Section 11) within?*
10 s of completing the drawdown.
10.5 Immediately clean the gage and repeat the pr<

12, Precision and Bias8
12.1 Precision: 12.1.1 An- interlaboratory study of this test method was conducted in which one operator in each of seven laborato ries made two determinations, each the mean ofreadings on four drawdowns, on two different days on six carbon black dispersions. The samples represented two different levels of premixing, each followed by one, two, or four passes on a roll mill The results were analyzed statistically in accordance with Practice E 691. On the basis of the standard deviations shown in Table 2, the following criteria should be used for judging the acceptability of results at the 95 % confidence level: 12.1.T.1 Repeatability--Two results, each the mean of readings on four drawdowns, obtained by the same operator should be considered suspect if they differ by more than the scale readings given in the last two columns of Table 2, Section A.-
12.1.1.2 Reproducibility--Two results, each the mean of readings oh four drawdowns, obtained by operators in different laboratories should be considered suspect if they differ by more than the scale readings given in the last two columns of Table 2, Section B.
12.2 Bias--Bias cannot be determined as there is no standard material. In the interlaboratory study described in 12.1.1, speckle endpoints were more sensitive to expected differences in degree of dispersion than were scratch endpoints.

1. Scope
5. Significance and Use
1.1 This test method determines quantitatively the fire retardant properties ofa coating or coating system on a wood surface and the leaching effect ofwater on the fire retardancy of the coating or coating system. Specifically, this test method determines the weight loss and char index of coated panels subjected to a flame and the effect of leaching ofthe
coating on these parameters. 1.2. This test method should be used solely to measure and
describe the properties of materials, products, or systems in response to heat and flame under controlled laboratory conditions and should not be considered or used for the description, appraisal, or regulation of the fire hazard of materials, products, or systems under actual fire conditions.
1.3 This standard does not purport to address the safety
problems associated with its use. It is the responsibility of whoever uses this standard to consult and establish appro
priate safety and health practices and determine the applica bility ofregulatory limitations prior to use.
5.1 This test method determines the relative fire-retardant properties of coatings and the water leaching of the fireretardant material from the applied coating. Leaching simu
lates the effect ofhigh humidity, weathering, and washing on the fire retardancy of a coating, and is specified in various regulations and specifications for fire-retardant paints.

of each panel, obtaining as uniform coverage as possible. Application can be by other conventional means and in as many coats to obtain the necessary weight of coating or desired wet or dry film thickness. Also coat the edges and sides of the panels with the same material. When applied in more than one coat, dry 24 h between coats under standard conditions (see 6.8) and, after the final coat, dry 14 days under the controlled conditions. Prior to subjecting the
specimens to the burning test, place them in the oven at 120 3F (50 2*C) for a period of 40 h.

9. Procedure--Fire Retardancy
9.1 Assemble the apparatus as shown in Fig. 1, including the stack extension and downdraft hood, in an area where facilities are available for the removal or escape of combus tion products (standard laboratory hood without forced ventilation). Weigh the panel to be tested to the nearest 0.1 g and record the weight Center the panel, face down, on the angular supports with the lower edge 2 in. (50 mmjfrom the angle formed by the floor and the side wall of the cabinet. Place the fuel cup, at room temperature, on the pedestal so that the vertical distance from the cup lip nearest to the face of the specimen is exactly 1.0 in. (25 mm). Using a buret or pipet, add 5.0 mL of pure absolute ethanol or any mixture with the same heat of combustion (Note 1) to the cup and ignite without delay by means of a flame approximately Vi in. (13 mm) in length. Close the door and adjust the draft to assure complete burning of the alcohol. Allow the test to continue until all flames self-extinguish. Repeat this proce dure with at least five replicate panels.
9.2 Weight Loss--Cool each panel to room temperature and weigh to the nearest 0.1 g. Determine the weight loss in grams of each of the five specimens by subtracting from its original weight (see 9.1). Calculate the mean and standard deviation for the weight loss. If the standard deviation of the five replicates is greater than 10% of the mean, test five additional panels and calculate the mean weight loss of the ten panels.
9.3 Char Index--Cut the panels by means of a finetoothed saw along the lines of maximum length and width of attack. Measure in centimetres the maximum width of charring of the wood panel below the paint film on the lateral cut Likewise, measure the maximum length of charring found on the longitudinal cut. Measure the max imum depth to which charring has penetrated the wood as evidenced on the longitudinal or lateral cuts. Determine the,
char index by multiplying the maximum char length, width,
and depth figures. Calculate the mean and standard devia tion for the char index. If the standard deviation of the five replicates is greater than 10% of the mean, test five addi tional panels and calculate the mean char index on the basis of the ten panels.
10. Procedure--Leaching Test
10.1 Prepare, coat, and condition 15 panels of each material under test as described in Section 8.
10.2 At the end of 14 days at 50 % humidity and 73.5'F
(23C), immerse the 15 panels in 2250 30 mL of water (150 mL/panet) (Note 3) for 40 h at 120 3F (50 2C).
N#$' 3--The water bath is made to contain 15 panels and 2250 mL
of water to cover the specimens. If less than 15 coated panels are
immersed, add blank panels to make up the i5.- Place panels so that
their faces do not touch. Cover the bath to prevent excessive evapora
tion.
>\
10.3 Subject each' ofthe if panels to the fire retardant test
in accordance with 9-1 and calculate the differences in mean weight loss and mean char index between the leached and the unleached set of specimens as follows: A wt. loss = mew wt, loss of leached specimens - mean wt.
loss of unleached specimens. A char index -- mean char index of leached specimens --
mean char index of unleached specimens.
11. Report
11.1` Report the following infbmiation: 11.1.1 The number of coats and the coverage in ft2/gal (m2/L) of the total numbers of coats for each set of each material under test, 11.1.2 The mean weight loss and the mean char index of the set exposed only to the fire retardancy test, the number of specimens used in calculating the means, and the final standard deviation, and 11.1.3 The difference in mean weight loss and mean char index between the sets of unleached and leached specimens as determined in 10.3.
12. Precision and Bias
12.1 The precision of this test is to be determined. 12.2 Bias--The bias of this test method cannot be deter mined as the value of fire retardancy can be defined only in terms of a test method.

3. Summary of Test Method
3.1 Instruments covered by this test method measure coating thickness by the use of eddy currents. The instru ment probe must be placed directly on the coating surface to take a reading.
4. Significance and Use
4.1 The instrument probe coil is energized by alternating current which induces eddy currents in the metal substrate. The eddy currents in turn create opposing alternating magnetic fields in the substrate that modify the electrical characteristics of the probe coil. The extent of such changes is dependent upon the distance between the probe and the metal, the distance being shown on the instrument meter as the thickness (mils or micrometers) of the intervening coating.
4.2 The accuracy of the measurements may be influenced when made closer than 1 in. (25 mm) to an edge or 3 in. (75 mm) to another mass of metal.
1 This test method is voder the jurisdiction of ASTM Committee D-1 on Paint and Related Coatings and Materials and is the direct responsibility of Subcom mittee DO 1.23 on Physical Properties of Paint Rims.

7. Calibration of Apparatus
7.1* Calibrate the instrument in an area free of stray magnetic fields, such as power lines, generators, or welding equipment. There shall be no vibration apparent on the test piece when the instrument is being calibrated.
7.2 Use a bare section of the substrate after the specified surface preparation method has been accomplished. If an uncoated section of the substrate is not available, uncoated test panels of a similar metal type over which the specified preparation has been performed may be used.
7.3 Use nonmagnetic thickness shims for calibration. Most shims are non-precision and therefore, thickness must be verified with a micrometer.
7.4 Select calibration shims in the expected thickness range to be measured. Ifa coating is expected to be 3 mils (75 pm) in thickness, calibrate the instrument at 3 mils. Then check the calibration using shims of both a lesser and greater thickness to determine the thickness range over which the instrument will register accurately.
7.5 Follow the manufacturer's instructions for the specific adjustment of the instrument.
8. Procedure
8.1 Use the instrument only after it has been calibrated in accordance with Section 7.
8.2 Assure that the coating is dry prior to use of the instrument.

9. Precision
9.1 Precision--On the basis of an interlaboratory study of this test method in which eddy-current instruments from four manufacturers were used in several laboratories to measure a moderate range of dry-film thickness on the same set of panels, the within-Iaboratory and between-laboratories coefficients of variation were found to be as shown in Table 1. Based upon these coefficients the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
9.1.1 Repeatability--Two results obtained by the same operator using instruments from the same category should be considered suspect if they differ by more than the maximum allowable difference values given in Table 1 for the appro priate film thickness.
9.1.2 Reproducibility--Two results, each the mean of four measurements, obtained by operators in different laborato ries using instruments from the same category should be considered suspect ifthey differ by more than the maximum
allowable difference values given in Table 1 for the appro priate film thickness.

N)*' 3--The panel should be so mounted that it cannot move with
respect to the stage in any direction during the course of the test.
9.3 Use the microscope to select an area of the test specimen that is free of surface irregularities and imperfec tions. Place this area under the indenter by means of the movable micrometer stage.
N+,' 4--If good impressions cannot be obtained because of the
roughness ofthe surface ofthe specimen, gently polish the surface with No. 400 carborundum and finish off with jewelers rouge before making the impression.

1 with included longitudinal angles of 172 30' and "lauded transverse angle of 130" O'.
-./' 1--The ratio of the long to the short diagonal of the impres-
' jj approximately 7:1; the ratio ofthe long diagonal to the depth of Creation is approximately 30:1.
73 Microscope--The microscope shall have a filar mi ster eyepiece and sufficient objectives to permit the measurement of the length of impression to within 1 %. jlte specimen shall be firmly supported on a movable micrometer stage attached to the microscope.
g. Calibration
8.1 Adjust the illumination in the microscope to give fljirimnm contrast when viewing an indentation.
8.2 By means of a calibrated scale, determine the factor for each microscope objective that will convert the filar scale units of the eyepiece to millimetres.
8.3 With a 25-g load on the indenter, determine the KHN ofa calibrated standard (Note 2) whose assigned value is not greater than 50 KHN. Ifthe obtained value is within 5 % of the assigned value, the instrument is considered .to be inr calibration.
N01' 2---A suitable source of calibrated standards in this hardness
range is not available. Therefore, by agreement ofthe parties concerned, istable specimen (such as an aged coating of a baked enamel applied to t flat substrate) should be used to calibrate the participating hardness testers.
9.4 - Preset the apparatus to apply a 25-g load and perform the test according to the manufacturer's instructions. Main tain the.time the indenter is in contact with the specimen for 18 04 s.
N23' 5--For maximum accuracy, care must be taken that the
indenter does not penetrate the coating to a depth beyond three fourths of the coating thickness. This is necessary to eliminate any major substrate effect on the hardness measurement
- 9.5 Immediately after the completion of the cycle, adjust the movable stage so that the indentation is in the field of the microscope. Focus the microscope on the indentation so that both extremities of the long diagonal (that is, where the upper edges of the indentation just converge) are as sharp as possible. Measure the length Of the long diagonal of the impression with the filar micrometer eyepiece.
N45' 6--Select a microscope objective that will cause the length of
impression to be between 200 and 800 filar units to assure maximum accuracy in measurement.
9.6 From the measurements obtained in 9.5, the informa tion given in Note 1, and the measured film thickness at the place of indentation, calculate the depth of indenter penetra tion. If the depth of penetration exceeds three-fourths of the coating thickness, the results may be influenced by substrate proximity. Therefore, for maximum accuracy it is desirable to prepare thicker specimens and repeat the test. Instead of this procedure, at the option of purchaser and seller, an indenter load of less than 25 g may be used.
9.7 Repeat the procedure described in 9.3, 9.4, and 9.5 until at least five impressions have been made at widely spaced locations on the specimen.

14.1 Hardness Testers--The hardness testers used in this method shall consist of a load applicator, a Pfund quartz or sapphire indenter, and a. microscope fitted with a stage. The apparatus shall be constructed so as to permit the indenter to be brought manually into contact with the specimen surface with negligible impact.
14.2 Pfund Indenter*--The Pfund indenter (Fig. 1) is a transparent colorless quartz or synthetic sapphire hemi sphere with a spherical radius of 0.125 in. (3.18 mm) and a maximum spherical eccentricity of 0.002 in. (0.05 mm).
14.3 Microscope--The microscope shall have a filar mi crometer eyepiece and sufficient objectives to jpermit the measurement of the diameter of impression to within 1 The specimen shall be rigidly supported on the microscope stage.
14.4 Timer, capable of measuring a time interval of 60 :
0.5 s.
15. Standardization
15.1 Adjust the illumination in the microscope to give maximum contrast when viewing an indentation.
15.2 By means of a calibrated scale, determine the factor for each microscope objective that will convert the filar scale units of the eyepiece to millimetres.
15.3 With a 1.0-kg load on the indenter, determine the PHN of a calibrated standard (Note 2) with an assigned value not greater than 40 PHN. If the value obtained is within 5 % of the assigned value, the instrument shall be consid ered to be in calibration.
16. Procedure
16.1 Unless otherwise specified, make the hardness deter mination at 73.5 3.5F (23 2C) and 50 5 % relative humidity, after holding the specimens under these conditions for not less than 24 h.
16.2 Rigidly attach the specimens to the instrument stage such that the surface to be measured is normal to the direction of indentation (Note 3).
16.3 With, a 1.0-kg load on the indenter, carefully bring the indenter into contact with the specimen surface, apply the full load, and start the timer.
16.4 At the end of 60 s, while still under full load, rapidly measure the diameter of the circular impression with the filar eyepiece of the microscope (Note 6). It is very important that the diameter measurements be made rapidly so that the time the indenter is in contact with the specimen is closely controlled.4
4 A hardness tester meeting the apparatus requirements of this method is the Head Indentation Hardness Tester, available from the United States Testing Co., IS Park Ave., Hoboken, NJ 07030.
16.5 From the measurements obtained in 16.4, the infor mation given in 14.2, and the measured film thickness at the place of indentation, calculate the depth of indenter penetra tion. If the depth of penetration exceeds three fourths of the coating thickness, the results may be influenced by substrate proximity. Therefore, for maximum accuracy it may be desirable to prepare thicker specimens and repeat the test.
16.6 Repeat the procedure in 16.3 and 16.4 until a total of at least five impressions have been made at widely spaced locations on the specimen.
17. Calculation
17.1 Calculate the mean indentation diameter in filar unils.-
17.2 Convert this mean indentation diameter to millimetres using the appropriate factor determined in 15.2.
17.3 Calculate the PHN as follows:
- PHN = 1.27jd2
where: d = mean indentation diameter, mm.
18. Report
18.1 Report the following information: 18.1.1 Mean and range of PHN values obtained for each specimen, stating the number of indentations made, 18.1.2 Mean film thickness of the specimen, based on measurements made near the points of indentation'; 18.1.3 Specimen preparation and conditioning techniques used, and 18.1.4 Mean and. range of PHN values of the replicate pqnejs.
19. Precision
19.1 On the basis ofan interlaboratory test of this method in which operators in four laboratories tested seven coated panels having a broad range of hardness, the within-laboratory coefficient of variation was found to be 6 % with 28 degrees of freedom and the between-laboratories coefficient 12 % with 18 degress of freedom. Based upon these coeffi cients, the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
19.1.1 Repeatability--Two results, each themean ofthree determinations on a specimen, obtained by the same oper ator should be considered suspect if they differ by more than 18 % of their mean value. `
19.1.2 Reproducibility--Two results, each the mean of three determinations on a specimen, obtained by operators in different laboratories should be considered suspect if they differ by more than 36 % of their mean value.

N89' I--The usual weight-per-gallon cup and similar specialized
pycnometers may have filled weights that exceed the capacity of the usual laboratory analytical balance. In such cases, use of a hanging pan, tnple-beam balance, with scales graduated to 0.01 g has been found to provide results the mean of which was consistent with the overall precision and accuracy ofthe method.
7.5 Desiccator and Desiccated Balance, or a room of reasonably constant temperature and humidity are desirable.
g. Calibration of Pycnometer or Cup
8.1 Determine the volume of the container at the speci fied temperature by employing the following steps:
8.1.1 Clean and dry the container and bring it to constant weight Chromic acid (see 8.1.1.1) or other effective glass cleaner and nonresidual solvents may be used with glass containers and solvents with metal containers. For max imum accuracy, continue rinsing, drying, and weighing until the difference between two successive weighings does not exceed 0.001 % of the weight of the container. Fingerprints on the container will change the weight and must be avoided. Record the weight, M, in grains.
8.1.1.1 Precaution--Chromic acid cleaning solution is corrosive to skin, eyes and mucous membranes and can cause severe bums. Avoid contact with eyes, skin or clothing. In making dilute solution, always add acid to water with care. In case of contact, flush skin with water, using ashower ifexposure is severe. Flush eyes for 15 minutes with copious amounts of water. Immediately call a physician. Remove clothing immediately and wash before reuse. Chromic acid cleaning solution is a strong oxidizer. Avoid contact with organic or reducing substances as a fire could results. See supplier's Material Safety Data Sheet for further informa tion. Other cleaners are much safer and may be equally effective.
8.1.2 Fill the container with freshly boiled distilled water at a temperature somewhat below that specified. Cap the container, leaving the overflow orifice open. Immediately remove excess overflowed water or water held in depressions ty wiping dry with absorbent material. Avoid occluding air bubbles in the container.
8.1.3 Bring the container and contents to the specified temperature using the constant-temperature bath or room if
necessary. This will cause further slight flow of water from the overflow orifice due to the expansion of the water with the rise of the temperature.
8.1.4 Remove the excess overflow by wiping carefully with absorbent material, avoiding wicking of water out of orifice, and immediately cap the overflow tube where such has been provided. Dry the outside of the container, if necessary, by wiping with absorbent material. Do not re move overflow that occurs subsequent to the first wiping after attainment of the desired temperature (Note 2). Imme diately weigh the filled container to the nearest 0.001 % ofits weight (Note 3). Record this weight, N, in grams.
N:;' 2--Handling the container with bare hands will increase the
temperature and cause more overflow from the overflow orifice, and will also leave fingerprints; hence, handling only with tongs and with hands protected by clean, dry, absorbent material is recommended.
N<=' 3--Immediate and rapid weighing of the filled container is
recommended here to minimize loss of weight due to evaporation ofthe water through orifices, and from overflow subsequent to the first wiping after attainment oftemperature where this overflow is not retained by a cap.
8.1.5 Calculate the container volume as follows:
V = (N -- M)/p
where: V = volume of container, mL, N = weight of container and water, g (7,1.4), M = weight of dry container, g (7.1.1), and p = absolute density of water at specified temperature,
g/mL (see Table 1). 8.1.6 Obtain the mean of at least three determinations.
9. Procedure
9.1 Repeat the steps in Section 8, substituting the sample for the distilled water and a suitable nonresidual solvent for the acetone or alcohol (see 8.1.2 and Note 4). Record the weight ofthe filled container, W, and the weight ofthe empty container, w, in grams.
N<=' 4--Trapping of paint liquids in ground glass or metal joints is
likely to result in high values of density that appear to increase with the viscosity and density of the material; such errors should be minimized by firm seating of the joints.
N>?' 5--Trapping ofair bubbles will result in low values for density.
The tendency to trap air increases with increasing viscosity. Specimens should not be tested if they contain bubbles or foam. Slow stirring, standing, or the application of a vacuum may remove bubbles. If these do not work, a dilution may be necessary (see Appendix X1).
9.2 Calculate the density in grams per millilitre as follows:
Dm = (W-w)/V
where:
Dm - density, g/mL.
9.3 Calculate the density in pounds per gallon as follows:
D = (W -- w)K/V
where:
D = density, lb/gal, K = 8.3454 (Note 6), and V = volume of container, mL (see 8.1.6).
179
DUP050297362
NOTE 6--The factor K, 8.3454, is calculated from volume-weight relationship as follows:
The results were analyzed statistically in accordance with Practice E 180. The within-laboratory coefficient of variation
8.345404 = [(2.54)3<* X (231.00)*]/(453.59237)c
was found to be 0.20 % relative with 25 degrees of freedom and the between-laboratoiy coefficient of variation was

0.61 % relative with 20 degrees of freedom. Based on these coefficients, the following criteria should be used forjudging the acceptability of results at the 95 % confidence level:

11.1.1 Repeatability--Two results, each the mean of du plicate determinations, obtained by the same operator on
10.1 In reporting the density, state the test temperature to the nearest 0.TC, the units, and the value calculated to the third place to the right of the decimal point (for example, D -- x.xxx lb/gal at 25C); state the mean, the range, and the number of replicate determinations.
11. Precision and Bias
11.1 The precision estimates are based on an interiaboratory study in which one operator in each of six different laboratories analyzed in duplicate on two different days five samples of paint ranging in density from 8.5 to 12.5 lbs/gl.
different days should be considered suspect if they differ by more than 0.6 % relative.
11.1.2 Reproducibility--Two results, each the mean of duplicate determinations, obtained by operators in different laboratories should be considered suspect if they differ by more than 1.8 % relative.
11.2 No data on bias has been generated for this test method.

5. Test Panels
5.1 Steel Panels--Steel panels as described in Methods D609.
5.2 Other test surfaces may be agreed upon between the purchaser and the seller of the finish being tested.
6. Chemical Agents
6.1 The choice of the agent shall be governed by ultimate coating use and by agreement between the purchaser and the seller ofthe finish being tested. The following staining agents are listed as being of general interest.
6.1.1 Glycol based antifreeze up to 100 volume, %. 6.1.2 Add, alkali, and salt solutions, 6.1.3 Soap and synthetic detergent solutions, ' 6.1.4 Lubricating oils and greases, 6.1.5 Polish abrasives, creams, waxes, 6.1.6 Road oils and tars; seam sealers, 6.1.7 Rubber or other elastomers; plastics, tapes, 6.1.8 Gasolines, 6.1.9 Water, 6.1.10 Hydraulic fluids, 6.1.11 Alcohol windshield washing compounds, and 6.1.12 Others.
7. Procedure
7.1 Panel Preparation--Carry out spot and direct applica tion tests on the fabricated article coated with the finishing system under evaluation, if sufficient plane surface is avail able. Otherwise, select panels in accordance with 5.1. Apply the finishing system in accordance with the method and schedule prescribed by the purchaser. Age the finished film to suit the exposure conditions, as agreed between the purchaser and the seller of the film-forming material.
7.2 Spot Testfor Liquid Agents--Conduct the test at 73 3.5*F (23 2"C) and 50 5 % relative humidity. Place a small portion of the staining agent on a horizontal test surface, making several spots approximately 1 in. (25 mm) in diameter. After the time agreed upon has elapsed, such as 4, 8,24, and 72 h, wipe off a spot, and examine it immediately for visual and physical evidence of the effects listed ip Section 4. Polish die test surface lightly with any suitable liquid car cleaner, and evaluate the surface in accordance with agreement on the basis of removability. Expose the test surface to sunlight for at least 8 h, or to strong ultraviolet light (Note 2) at 150T (65C) or less as agreed upon, for 1 h. Evaluate the surface on the basis of either disappearance of defects or development of defects not previously visible.
181
DUP050297364
# D 1540
Prepare surfaces for water spotting tests by exposing them to an RS ultraviolet lamp for 6 h, and then polishing. Then proceed as follows: apply water drops, heat in an oven at 150F for 15 min, and then lightly polish. Any variations in the procedure shall be as agreed upon between the purchaser and the seller of the film-forming material.
NDE' 2--The RS sunlamp manufactured by the General Electric Co. is recommended for this test. Other ultraviolet light sources are acceptable if agreed upon by the purchaser and seller, and if the appropriate exposure equivalent is known and used.
7.3 Contact Test for Solids--The materials listed in 6.1.7 may produce a deterioration of the appearance in several of the ways listed in Section 4, but must be held in close contact with the surface. Frequently the agent may cause an effect only when heated, therefore, they should be heated for this test. Test finishes with rubber as a staining agent, in accordance with Test Methods D 925. Plastics may be hdld in contact with the finish, and tested as described in 7.2.
7.4 Gasoline (Caution; Note 3)--To determine the' staining effect of gasoline, place some in a buret Allow th^ gasoline to fall 4 in. (100 mm) onto the test surface placea below and at an angle of 20 from the horizontal. The dropping rate should be about 10 drops per minute. Place an
RS sunlamp (Note 2) 15 in. (380 mm) from the test surface so that its rays shine at 90 to the surface. Continue the test until 200 mL of gasoline have been dropped during 3 V2 h.
NFG' 3: Caution--This test should be run where there is adequate ventilation,'and'provision should be made for draining the drippings into a safety can. Other precautions against fire should be observed.
7.5 In evaluating the results, the 0 to 10 scale prescribed in ASTM STP 50(f should be used.
8. Report
8.1 Report the following information: 8.1.1 The system and the test method employed. Test conditions are an important factor in the results obtained, and therefore, should be defined in the report 8.1.2 The type and appearance of the effect obtained, if any, (see Section 4). It is customary to record stain-free contact time as a basis of comparison. Where agreed, the effect of the agent may alsobe evaluated by the use of a color difference meter spectrophotometer, glossmeter, hardness instrument or other applicable apparatus.

3.4 Sulfuric Acid Reagent--Add 35.7 mL of concentrated sulfuric acid (H2S04, sp gr 1.84) slowly to 34.7 mL of water, and cool to room temperature. Store in a glass-stoppered bottle. -
4. Procedure
4.1 Lieberman-Storch Test--Place 0.1 to 0.2 g of the sample in a test tube, and add 15 mL of acetic anhydride. Heat gently until the specimen is dissolved or dispersed. Cool and filter with an ashless rapid filter paper, into a clean test tube. Place a few drops of the clear solution in a depression of the spot plate, and add one drop of sulfuric acid reagent, so that the add will mix slowly with the filtrate. If rosin is present, a fugitive violet color develops immediately. A pink or brown coloration should be ignored. A control spedmen containing rosin should be run simultaneously.
4.2 Halphen-Hicks Test--Dissolve a small quantity of the sample in 1 to 2 mL ofthe phenol reagent Pour the solution into a cavity of the spot plate until it just fills the depression. A portion of the solution will spread out on the flat part of the plate a short distance beyond the rim of the cavity, unless too much of the carbon tetrachloride has been lost by evaporation, when a drop or two more should be added to produce the spreading effect referred to. Immediately in an adjacent cavity, place 1 mL or more of the bromine reagent, so that the bromine vapors evolved will contact the surface of the solution in the other cavity. Sometimes it is necessary to blow a gentle current of air in the proper direction to accomplish this satisfactorily, or both cavities may be cov ered by a watch glass of suitable size. The development of a fugitive violet coloration, best observed upon a flat portion of the test plate, indicates the presence of rosin.

6. Precision and Bias
6.1 On the basis of a study in which one observer at each of 80 laboratories made duplicate determinations on four samples, the "between" and "within" standard deviations were found to be 0.5 and 0.1 color number, respectively. Based on these standard deviations, the following criteria should be used forjudging the acceptability of results at the 95 % confidence level.
6.2 Repeatability--Two results obtained by a single oper ator should be considered suspect if they differ by more than two thirds of a color number.
6.3 Reproducibility--Two results, each of the mean of duplicate measurements, made by operators in different laboratories should be considered suspect if they differ by
more than four thirds of a color number.
NMN' 1--If desired, liquid standards matching the colors given in
Table 1, in glass tubes similar to the sample tubes may be used. These
may be filled with potassium chloroplatinate for the light colors and solutions of ferric chloride and cobalt chloride in hydrochloric acid for
the darker colors. The specifications and approximate composition of these solutions are given in Test Method D 1544 - 58 T.4 Many Glass
Standards in current use do not conform to the values of Table 1.
NMN' 2--The precision data were obtained using an instrument in
which two standards are viewed simultaneously. There are other instruments available for color matching which would be expected to give similar results, but the statement above applies only to the instrument checked.

XI. CALIBRATION OF GLASS REFERENCE STANDARDS
Xl.l Select a dual beam spectrophotometer with a suffi ciently small light beam at the sample position so that all rays will pass through the standards to be calibrated. Alter natively equip the spectrophotometer with a condensing lens to accomplish this purpose.
X1.2 Place the standards in turn in the sample position of the spectrophotometer. If the comparator is provided with a separate green filter in front of the light source, place this
filter in the reference beam ofthe dual beam spectrophotometer during calibration of each standard.
X1.3 Obtain spectral transmittance data for each glass reference standard by following Method E 308.
X1.4 From the spectral transmittance data for each reference standard calculate the CIE tristimulus values, X, Y, Z, and the chromaticity coordinates, x, y, for CIE Illuminant C (see Method E 308).

Standard Test Method for Viscosity of Transparent Liquids by Bubble Time Method1
This standard is issued under the fixed designation D 1545; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year oflast reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.
This standard has been approvedfor use by agencies ofthe Department ofDefense to replace Method 4271 of Federal Test Method Standard No. 141. Consult the DoD Index ofSpecifications and Standardsfor the specific year ofissue which has been adopted by the Department ofDefense.
1. Scope 1.1 This test method covers the determination of the
viscosity in bubble seconds by timing. The bubble seconds are approximately equal to stokes for most liquids.
1.2 The test method is applicable to transparent liquids that are free from crystalline or gel particles.
1.3 This standard may involve hazardous materials, operdiions, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is ihe responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
I, Terminology
2.1 Definition: 2.1.1 viscosity--the resistance experienced by one portion of a liquid moving over another portion of the liquid. The absolute unit of viscosity in the cgs system is the poise which is expressed as dyne-seconds per square centimetre. Stokes are equal to poises divided by density. The absolute SI viscosity unit is the pascal-second.
3. Apparatus 3.1 Constant-Temperature Bath--Any suitable bath ca
pable of maintaining temperature at 25 0.1C with water as the bath medium.
3.2 Standard Viscosity Tubes,2 of clear glass and with flat bottoms, 10.65 0.025 mm in inside diameter, 114 1 mm in outside length. Plainly legible lines shall be located as follows (Note 1):
27 0.5 mm 100 0.5 mm 108 0.5 mm
The distance between the first and second lines shall be 73
0.5 mm.
NOP' 1--All distances shall be measured from the outside bottom of
the tube.
3.3 Reference Standards--A series of standard viscosity
1 This test method is under die jurisdiction ofASTM Committee D-l on Paint and Related Coatings and Materials and is the direct responsibility of Subcom mittee DO 1.33 on Polymers and Resins.
Current edition approved Oct. 27, 1989. Published December 1989. Originally Published as D 1545 - 58 T. Last previous edition D 1545 - 76(1989)".
'Empty standard viscosity tubes are available from the R. P. Cargille Laboratories, Inc., 33 Village Park Rd.. Cedar Grove, NJ, or Byk-Gardner Inc., Gartner Laboratory, 2435 Linden Lane, Silver Spring, MD 20910.
tubes (3.2) filled with transparent liquids having predeter mined viscosities in stokes and bubble seconds and spaced in logarithmically even increments of about 26 % (log 1.260 = 0.100), as listed in Table 1. The standards shall be marked alphabetically or numerically as shown in Table 1 without reference to stokes or bubble time (Note 2). Also listed in Table 1, for general and historical reference only, is the long established series of Gardner-Holdt letter standards, in tubes that do not have the three lines and are shorter than the standard viscosity tubes described in 3.2.
NQR' 2--For convenience, the reference standards can be divided in three series: light series, 15 tubes marked 0.22 to 8.0; heavy series, 14 tubes marked 10 to 200; and very heavy series, 7 tubes, marked 250 to 1000.
3.4 Timing Device--Stopwatch or electric stop clock capable of being read to a precision of 0.1 s.
3.5 Tube Racks, capable of inverting one or more viscosity tubes 180 to within 1 of a vertical position while rack and tubes are immersed in the constant temperature bath.
3.6 Viscosity Tube Corks, No. 2 short.
4. Procedure
4.1 Fill a standard viscosity tube with the material to be tested to approximately level with the 108-mm line.
4.2 Transfer the tube to a constant 25C temperature bath with the cork loosely inserted. Hold at this temperature for 10 min.
NST' 3--Adequate control of the temperature bath is essential. A variation of 0.1C in the temperature of the bath will cause a 1 % variation in the timed bubble travel.
4.3 At the end of 10 min adjust the level of the liquid so that the bottom meniscus will be level with the 100-mm line. Insert the cork so that the bottom of the cork is on the level with the 108-mm line. This will ensure a bubble of suitable and uniform size,
4.4 Insert the tube in the rack and immerse in the 25C water bath. Allow the tube(s) to stand with cork down in the bath a minimum of 20 min before determining the viscosity.
NUV' 4--For viscosities ofliquids that have a timed bubble travel of 4 s or less, more precise results can be obtained by comparison against reference standards having a predetermined viscosity or timed bubble travel.
4.5 To read, invert the tube quickly and determine the time required for the bubble to rise in seconds. When determining the time in seconds start the timing device when the top of the bubble becomes tangent to the 27-mm line on

the tube. Stop the timing when the top of the bubble becomes tangent with the 100-mm line. This gives a 73-mm timed bubble travel. All timings shall be made with the tube in an exact vertical position.
NWX' 5--Positioning ofthe tube in a vertical position is mandatory.
A tube one radius off the vertical will give an error of approximately 10 % in the time of bubble travel.
5. Report
5.1 Report the following information: 5.1.1 The viscosity obtained by the timing method expressed as "bubble seconds" or "approximate stokes."
NYZ' 6--The time in seconds or "bubble seconds" is an approxi
mate measurement ofstokes when the bubble time method is applied to most raw materials and finished products encountered by the paint, varnish, and lacquer industries. This relationship does not hold for silicones or water dispersions of gums or similar materials. Viscosity results by this test method are influenced by non-Newtonian behavior aifd by surface tension. Other variations on bubble-tube viscometers are described in ASTM STP 500, Section 3.2.9.3
6. Precision and Bias
6.1 On the basis of an interlaboratory study4 of this test method in which ten laboratories tested liquids ranging in viscosity from 4.5 to 440 St, the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
6.1.1 Two results obtained by the same operator should be considered suspect if they differ by more than 4.9 % relative.
6.1.2 Two results, each the mean of duplicates, obtained by operators in different laboratories should be considered suspect if they differ by more than 9.0 % relative.

5. Panel Preparation
5.1 Sand the five maple panels with No. 00 garnet paper until the surface is flat and smooth. Remove the excess sanding dust with a clean dry cloth.
5.2 Apply a liberal coat of sealer to the panels using a pad of clean cheesecloth. Note fluidity and ease of application. Allow the sealer to set 15 min for absorption into the wood. Wipe off the excess sealer using a pad of cheesecloth (note , whether the excess sealer removed in this manner can be wiped readily and cleanly from the surface). The surface shall be free of all excess sealer. Allow the panels to dry 24 h at a temperature between 70 and 90T (21.1 and 32.2'C).
5.3 Apply a second coat of sealer following the procedure described in 5.2.
N[\' 2--Other methods of application and panel preparation may
be used when agreed upon by the purchaser and the seller.
6. Procedure
6.1 Appearance ofFinish--Examine the panel, treated as described in Section 5, for the presence of surface film. Note whether the treated surface of the panel has a soft, even sheen and whether the grain of the wood is douded or obscured.
6.2 Resistance to Ink Stain--Place several drops of blueblack ink on the surface of a treated panel at various places and allow to remain for 3 min. Take up the ink with blotting paper and wipe the spots lightly with a damp cloth. Examine the surface for any indication of the presence of ink.
6.3 Treatment of Worn Spots--Simulate on a treated panel worn areas by rubbing the surface with No. 0 steel wool. Over these pands apply a thin coat of sealer. Burnish the worn areas with No. 00 steel wool immediately after application of the sealer. When dry, examine the treated areas to determine whether they blend with the surface ofthe panel without showing any signs of lap marks.
6.4 Application, of Finishing Materials--To a treated panel apply a finish coat of the varnish. To a second treated panel apply a coat of the solvent wax. To a third treated panel apply the emulsion wax. Note whether the properties ofthe finishing materials are adversely affected by the sealed surface or whether the finishing material adversely affects the sealed surface.

6.1.2 Apply the materials to be tested on clean glass panels or other specific substrate of suitable dimensions agreed upon between the purchaser and the seller. Groundg]ass plates are more suitable for certain types of coatings jjiat tend to crawl, such as low-viscosity drying oils. Suitable
plates can be prepared by roughening the surface of polished glass by grinding a paste of silicon carbide (grit 1-F) and water between two glass plates.
6.1.3 The test films perferably shall be cast with a doctor blade having a clearance sufficient to give the recommended dry film thickness indicated in Table 1. When a suitable doctor blade is not available, or it has been agreed upon to apply &e film in some other manner, the various conven tional and automatic methods ofspray, dip, flow, and brush 1 application may be used, provided dry film thicknesses
conform to the requirements given in Table 1. See Test [Methods D823 for a description of the spray and dip" methods of application.
6.1.4 Measure the dry film thickness of test films with the proper film thickness gage. This shall be a micrometer, dial comparator, or dial indicator as described in Test Methods D1005. When plates of small area are used, measurement of dry film thickness can be made by weighing plates before and after coating and calculating from plate area and coating solids.
7. Procedure
7.1 When test methods or end points other than those listed in 7.2 to 7.9 are used, there shall be a prior agreement between the purchaser and the seller.
7.2 Set-To-Touch Time--To determine set-to-touch time, lightly touch the test film with the tip of a clean finger and immediately place the fingertip against a piece of clean, clear glass. Observe if any of the coating is transferred to the glass. For the purpose of this test, the pressure of the fingertip against the coating shall not be greater than that required to transfer a spot of the coating from l/s to V\t> in. (3 to 5 mm) in cross section. The film is set-to-touch when it still shows a tacky condition, but none of it adheres to the finger.
7.3 Dust-Free Times: 7.3.1 Cotton Fiber Test Method--Separate a number of individual fibers from a mass of absorbent cotton with the

aid of tweezers. At regular drying intervals, drop several of the cotton fibers from a height of 1 in. (25 mm) onto a marked section of the film. The film is considered to have dried dust free when the cotton fibers can be removed by blowing lightly over the surface of the film.
7.3.2 Powder Test Method--Deposit finely divided cal cium carbonate (pigment grade) on the film at definite intervals during the drying period and, after the film has dried tack-free, remove by blowing with a gentle stream ofair and wiping with a soft rag or camel-hair brush. The coating is considered dust-free at the time interval when the pigment can be removed completely.
7.3.2.1 Deposit the calcium carbonate from a box through a 160-mesh screen in a pattern IV2 in. (40 mm) long and % in. (10 mm) wide. Fasten a vibrator to the side of the container to facilitate the passage ofthe pigment through the screen in a uniform pattern. Support the apparatus so that there is a clearance ofabout % in. (3 mm) between the screen and the test film. Figure 1 shows a typical dust-free tester7 and Fig. 2 shows the pattern obtained in testing a black enamel. The enamel shown is considered dust free at the 41/2-h rating.

7.4.1.2 Lay a 2 by 3-in. (50 by 75-mm) piece ofthe special test paper on the film and place upon it a steel cylinder 2 in. in diameter, and of such weight 6.28 lb, (2.85 kg), as to produce a pressure of 2 psi (13.8 kPa). At the end of 5 s, remove the cylinder and invert the test panel. The film is considered free from after-tack when the paper drops off of the test film within 10 s.
7.4.2 A variation of the test method described in 7.4.1 using the same test paper can be used to test the tack-free time of insulating varnishes. In this method the piece of paper shall be 1 lh in. (40 mm) in width and 6 in. (150 mm) in length. The varnish is considered tack-free when this strip of paper does not adhere to it when it is pressed on the surface of the varnish for 1 min by a cylindrical 1-lb (450-g) weight, l in. (25 mm) in diameter. In this test, apply .the paper in the vicinity of the center of the specimen at right angles to the length of the coated specimen.
7.4.3 Mechanical Test Method (Tack Tester9)--The tack tester to be used in this method comprises essentially a base or surface-contacting portion 1-in. (25-mm) square and a counter-balancing portion 1 by 2 in'. (25 by 50 mm) in area. Both portions are made up from a continuous metal strip
9 The standard tack tester is fully described in the U. S. Patent 2,406,989, Sept. 3, 1946.
0.016 to 0.018 in. (0:41 to 0.46 mm) in thickness. To prepare
the apparatus for use (see 7.4.3.1), fit the base with several thicknesses of masking tape and paper strips to provide a means of attaching the aluminum foil and so adjust the angle of the 1 by 2-in. counter-balancing strip so that a weight of 5 g placed in the geometric center of the base portion is just sufficient to overcome the unbalanced force.
7.4.3.1 The tester is prepared for use by carrying out the following steps in sequence:
(1) Wrap the metal base with three thicknesses of masking tape, sticky side out,
(2) Cover the outer layer with a good grade of paper, except for two exposed strips, equally spaced, about ]A by 1 in. (6.4 by 25 mm) in area on the top of the tester, and
(J) Cover the paper on the contact side of the base with one thickness of pressure-sensitive cellulose tape previously fixed to the metal base ofthe tester. The cellulose tape serves two purposes:
First, to pull the layers of masking tape firmly against the front of the metal base, and -- Second, to provide a smooth surface for the foil. Attach the aluminum foil to the base of the tester by pressing gently but firmly a 1 by 2-in. (25 by 50-mm) piece of foil, 0.0005 in. (13 pm) in thickness against one of the `4 by 1-in. (6.4 by 25-mm) exposed strips of masking tape on the top surface of
the base. Wrap the foil tightly and smoothly around the base, exposing the shiny side, and finally press the outer end gently against the remaining exposed strip of masking tape. When it finally becomes necessary to replace wrinkled or soiled aluminum foil, the ends are easily removed from the masking tape by exerting a slow, even, upward pull sufficient to overcome the tack of the tape without tearing the foil.
7.4.3.2 A film is considered to have dried tack-free when the tack tester tips over immediately on removing a 300-g
weight allowed to act for 5 s on the counter-weighted metal square base fitted with masking tape and aluminum foil.
7.5 Dry-To-Touch Time:
7.5.1 Drying Oils--Continue testing after the set-to-touch time has been observed. The film is considered dry when it no longer adheres to the finger and does "not rub up appreciably when the finger is lightly rubbed across the surface.
7.5.2 Lacquers (and Sealers)--Touch the film lightly at varying intervals of time. The film is considered dry when no pronounced marks are left by the finger touching the film in the same area on each observation. Test sealers on wood or other porous substrates as agreed upon between the pur chaser and the seller.
7.6 Dry-Hard'Time: 1.6.1 With the end of the thumb resting on the test film and the forefinger supporting the test panel,, exert a max imum downward pressure (without twisting) of the thumb on the film. Lightly polish the contacted area with a soft cloth. The film is considered dry-hard when any mark left by the thumb is completely removed by the polishing operation. 7.7 Dry-Through (or Dry-To-Handle) Time: 7.7.1 Place the test panel in a horizontal position at a height such that when the thumb is placed on the film, the arm of the operator is-in- a vertical line from the wrist to the shoulder. Bear down on the film with the thumb, exerting the maximum pressure of the arm, at the same time turning

2--This procedure is similar to Test Method D 2091, except itst the time to reach the print-free condition is determined, while Test jjjgjliod D 2091 is used to evaluate whether a film is print free at a
spedBed time.
7.9.1 Test Panels--Apply the material under test to clean ulsiie panels, at least 3 by 6 in. (75 by 150 mm) in size, made of wood, metal, glass, plastic or other material as agreed upon between the purchaser and the seller.
7.9.2 Imprinting Fabric--Eight-ounce Army duck conforming to Type III of U.S. Fed. Spec. No. CCC-C-419b or cheesecloth conforming to Fed. Spec. No. CCC-C-440.
7.9,2, l A pad should be used with the cheesecloth only, made of nonwoven felt cloth at least 0.05 in. (1.3 mm) thick, yfighing 7 oz/yd2 (0.24 kg/m2) and larger than the plane end

than 2 in. (50 mm) in diameter with plane ends perpendic ular to the axis and of a length to give a pressure of 'h or 1 lb/in.2 (3.5 or 6.9 kPa).
7.9.4 Procedure: 7.9.4.1 Apply the test material to several of the specified or agreed-upon panels by a film applicator, or other specified method, as described in Test Methods D 823 in either single or multiple coats, as agreed upon between the purchaser and
the seller. In the absence of a specified dry film thickness, the values listed in Table 1 should be used.
7.9.4.2 Allow the coated panels to dry under the condi tions specified in Section 5, unless otherwise agreed. At appropriate intervals, starting shortly before the coating is expected to be print-free, carry out the print-free test as described in Test Method D 2091, comparing the appear ance with the photographic standards appearing therein, until the test shows the coating to be print-free.
8. Frequency of Testing
8.1 It is suggested that test intervals be set at periods of approximately 10 % of the total test time. If frequency varies considerably from the 10 % interval or such time interval is impractical, the intervals used shall be reported.
9. Report 9.1 Reports of tests shall include all applicable conditions
that deviated from the standards as outlined or special conditions or tests used and the results of the test.
10. Precision 10.1 Because of the subjective nature of the drying time
tests, the agreement to be expected between laboratories depends upon their understanding of the terms used, and is difficult to establish with certainty. Within any laboratory, the agreement depends upon the material being tested, some coatings being much sharper in their end point than others, but duplicate determinations should agree within 10 % ofthe time of drying.10

1. Scope
1.1 These methods cover the determination ofelasticity or toughness of any varnish which is miscible with the diluents specified, under the conditions ofthe test.
1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.
2. Summary of Methods
2.1 Elasticity or toughness of the varnish may be deter mined by proportionately reducing its elasticity or toughness by the addition of a standard solution of a resin. The .long-accepted use of run-kauri gum may now be less convenient due to a limited supply ofthis resin. Accordingly, an equally acceptable resin is prescribed in Method A (Sections 3 to 6). Method A is based on the preparation of a rosin-pentaerythritol ester, the properties of which in terms of acid value and melting point can be controlled, and on a solvent that is free of any inherent polymerization tendency. Where desired, run-kauri gum may be used as prescribed in Method B (Sections 7 to 9).
2.2 For varnishes that are less elastic or tougher than zero standard resin reduction, Method C (Sections 10 to 13), based on proportionately increasing the elasticity or tough ness of the varnish by means of the addition of linseed oil, is provided.

4, Test Panels
4.1 Test panels shall be No. 31 gage (0.227 mm) bright tin plate weighing not more than 0.51 nor less than 0.39 lb/ft2 (25 or less than 19 g/dm2). It is important that the tin plate shall be within the limits prescribed. The panel shall be about 3 by 5 in. (76 by 120 mm) and shall be thoroughly cleaned vdth benzene immediately before using (cleaned but not buffed) and wiped dry with a clean cloth.
j. Procedure
5.1 Reduction of the Varnish--Carefully determine the nonvolatile matter content of the varnish under test, as described in ASTM Methods D 1644, Test for Nonvolatile Content of Vamishes.s Then take at least 10 g of the varnish and add to it an amount of the standard resin solution equivalent to the specified percentage reduction by weight of the nonvolatile matter in the varnish. Mix the varnish and the solution thoroughly.
5.2 Application of Reduced Varnish--Flow a coat of the teduced varnish on one ofthe tin panels described in Section 4, Let stand in a nearly vertical position at room temperature 70 to 90 F (21 to 32 C) for 1 h. Place the panel in a horizontal position in a properly ventilated oven and bake for 5 h at 203 to 212 F (95 to 100 C). Remove the panel from the oven and allow to cool at 77 F (25 C) for 30 min.
5.3 Bending of Test Panel--Quickly bend the coated panel over a %-in. (3-mm) rod held firmly by suitable supports. With the coated side ofthe panel uppermost, place it in position on the rod so that the rod is equidistant from the top and bottom edges of the panel. Bend the panel double in 1 s at a temperature of 77 0.2 F (25 0.1 C). Examine the film at the bend under a magnification of 5 diameters, using diffused light having a color temperature of 6500 K and intensity of about 165 ft-candles (1770 be). (For those not equipped with a standard illuminant, viewing the panel at a north window illuminated by a farily light overcast sky will approximate these conditions.) No cracks shall occur over the bent area between the points lA in. (6.4 mm) from each side of the panel.
6. Report
6.1 Report varnishes that do not show cracks under this test as passing the percentage of standard resin reduction specified.
6.2 If a limiting percentage rather than a specified per centage is desired, successive changes of 10 % standard resin reduction, based on the nonvolatile matter content of the varnish, shall be made until a limiting percentage is found. For example, varnishes may be reported as passing 40 % standard resin reduction and breaking at 50 %.
METHOD B--RUN-KAURI REDUCTION
7. Preparation of Standard Run-Kauri Solution
7.1 Weigh into a side-tube type distillation flask of suit able size an amount of clear, hard, bright pieces of "No. 1
Grade" kauri gum, equivalent to approximately one third of the volumetric capacity of the flask. Attach the flask to a water-cooled condenser. Carefully melt and distill the gum, collecting the distillate in a tared receiver. Stop the distilla tion when 25 % by weight of the gum has been collected in the tared receiver. A thermometer so placed in the distilling flask that its bulb is level with the discharging end of the flask should read about 600 F (316 C) at this point. Pour the residue in the distillation flask into a clean pan, and when cool break it up into small pieces.
7.2 Place in a tared beaker a given weight of the small pieces ofthe run-kauri gum, which shall be free from all dust or powder, together with twice its weight of freshly distilled gum spirits of turpentine conforming to ASTM Specification D 13, for Spirits of Turpentine,4 using only that portion distilling between 307 and 338 F (153 and 170 C). Dissolve the gum in the turpentine by heating the contents of the beaker slowly to a temperature of 302 F (150 C). The contents Of the beaker should be stirred occasionally to prevent the sootened gum from adhering to the bottom ofthe beaker, thus avoiding possible over-heating of the gum and facilitating its solution. Allow the solution to cool to between 167 and 212 F (75 and 100 Q and filter through a fluted filter paper into a previously weighed, clean, brown glass bottle equipped with a screw cap.
7.3 Examination of Run-Kauri Solution for Solvent
Compatibility--To 5 ml of the run-kauri solution in a clean, clear glass tube add 5 ml of mineral spirits conforming to
ASTM Specification D 235, for Petroleum Spirits (Mineral Spirits),4 and in addition having an aniline point of between 55 and 60 C determined in accordance with ASTM Method
D 611, Test for Aniline Point and Mixed Aniline Point of Petroleum Products and Hydrocarbon Solvents.6 Mix thor oughly and allow to stand for 1 h at room temperature, between 70 and 90 F (21 and 32 Q. At the end of 1 h the mixture shall be completely miscible and show no clouding, precipitation, or separation. If clouding, precipitation, or separation occurs, the run-kauri solution shall be considered unsatisfactory for use.
7.4 Adjustment ofRun-Kauri Solution to Proper Nonvola tile Matter Content--Transfer 10 to 15 ml of the filtered run-kauri solution to a stoppered flask or weighing pipet and determine the percentage of nonvolatile matter as described in Methods D 1644, with the following modifications: Add approximately 2 g of raw castor oil, accurately weighed, to each 80-mm dish or lid before adding the run-kauri solution and heat for 3 h at 115 2 C. At least three determinations shall be made, using samples of run-kauri solution weighing 1.2 0.1 g, and at least two blanks shall be run on the castor oil alone under the same conditions to determine its loss in weight Calculate the nonvolatile matter content of the run-kauri solution, making allowance for the loss in weight of the raw castor oil. From the average nonvolatile matter content thus determined and the weight of the run-kauri solution, calculate the amount of freshly distilled gum spirits of turpentine required to adjust the nonvolatile matter content of the run-kauri solution to 33.3 weight %. After the

addition ofthe required amount ofthe turpentine, repeat the nonvolatile matter determination and record the nonvolatile matter content, which shall be 33.3 0.1%.
8. Procedure 8.1 Using test panels prepared as in Section 4, and
run-kauri solution as in Section 7, follow the procedure described in Section 5.
9. Report 9.1 Report as directed in Section 6, expressing the results
in terms of run-kauri reduction instead of standard resin reduction.
METHOD C--ADDITION OF UNSEED OIL
10. Scope 10.1 This method is applicable to varnishes that are less
elastic or tough than zero standard resin reduction. It is identical with that described in Method A, except that the 33% % solution of standard resin in hi-flash naphtha i$ replaced by a 66% % solution of heat-bodied linseed oil for proportionately increasing the elasticity of the varnish under test
11. Preparation of Standard Bodied Oil Solution
11.1 Heat a high grade of alkali-refined linseed oil having an acid number less than 1.0 in an open kettle at a temperature of 300 5 C until the viscosity of the oil after cooling is between 6 and 10 St (0.0006 and 0.0010 m2/s) at 77 F (25 C).
11.2 Standardize a quantity of the heat-bodied linseed oil by reducing it with one half its weight of pure redistilled turpentine conforming to Specification D 13,4 using only that portion of the turpentine distilling between 307 and 338 F (153 and 170 C).
12. Procedure
12.1 Prepare the test panels and perform the addition of the standard bodied oil solution to the varnish and the flowing on, baking, and bending of the test panel exactly as described in Section 5.
13. Report
13.1 Report the minimum percentage of the oil solution that must be added to the varnish, based on its nonvolatile matter content, so that the final mixture when flowed on a test panel and-baked does not crack on the subsequent bending over a 3-mm rod.
14. Precision
14.1 The precision of this method is limited by the character of the testing ingredients and procedures and the interpretation and visual observation of the results. These, results are not specifically numerically oriented and, there fore,, .comparison with standards of control materials known to have acceptable properties, determine the precision.

GAS CHECKING
3, Scope 3.1 This test method3 covers two alternative procedures
for detecting nonuniform appearance that may develop while a film of varnish dries in an atmosphere that has been fouled by products of combustion. The nonumform appear ance is generally related to wrinkling, which is sometimes microscopic and which is variously described as checking, crow's-footing, crystallization, or dulling. Appearance non uniformities that develop on dried films and are described by such terms as orange-peel, haze, silking, flooding, etc., arenot within the scope of this test method.
4. Summary of Test Method 4.1 The varnish film under test is exposed to foul. gas for
various periods before the film has been' converted from liquid to substantially solid, since the foul gas is effective, within the scope of these test methods, only before the varnish film has become set-to-touch or dust-free.

PROCEDURE A--BELL JAR TEST
5. Apparatus
5.1 The form and arrangement of the apparatus shall be designed to provide an even distribution of the products of combustion over die test panels.
5.1.1 Glass Bell Jar, approximately 8 in. (203 mm) in diameter and 12 in. (300 mm) in height, inside dimensions, having a ground-glass rim.
5.1.2 Ground-Glass Base Plate, of suitable size. 5.1.3 Metal Frame, fitted inside the bell jar and provided with a suitable support for holding a tin-plate disk 6 in. (152 mm) in diameter in a horizontal position 2 in. (51 mm) above the wick of the lamp. 5.1.4 Additional Horizontal Supports, for holding the various varnished panels under test. 5.1.5 Small Kerosine Glow Lamp, without a chimney, or a small alcohol lamp filled with kerosine, using a round wick not over `A in. (6.4.mm) in diameter and adjusted to give a flame of Vs in. (20 mm) in height. 5.1.6 Tin-Plate Panels, 3 by 5 in. (76 by 127 mm) or smaller, cut from commercial No. 31 gage (0.227 mm) bright tin plate, weighing 0.39 to 0.51 lb/ft2 (1.9 to 2.5 kg/m2) and carefully cleaned with toluene and dried before use.
6. Procedure.
6i 1 Determine the normal set-to-touch or dust-free drying time of the varnish under test in accordance with Test Methods D 1640. Divide this time by five to arrive at the different drying periods at which the material is to be tested. Thus, if a .material sets to touch in 1 h, test the specimens for resistance to gas at drying periods of 12, 24, 36, and 48 min, .respectively,.
6.2 Flow the varnish to be tested on the tin-plate panels at the determined intervals of time. Allow the panels to drain in a nearly vertical position at room temperature 65 to 75F (18 to 24C).
6.3 After the required interval of drying time has passed, place the panels in a horizontal position on the upper supports of the frame. Light the lamp and place it on or near the center ofthe ground-glass base plate. After the bell jar has been placed tightly over the frame and lamp, the flame should extinguish in about 4 min.
6.4 Remove the panels and examine for gas effects after they have remained in the jar for 30 min.

}, Summary of Test Methods
3.1 Test Method A--The material under test is flowed onto tinplate panels and dried for 48 h. The panels are then immersed to half their length in reagent water for 18 h, pr other agreed upon time, removed, and examined visually.'s
3.2 Test Method B--The material under test is applied* to glass test tubes by dipping and dried for 72 h. The tubes are then suspended in dilute sodium hydroxide for periods ranging from 1 to 24 h, removed, rinsed, and after drying for 30 min, examined visually.
4. Significance and Use
4.1 Dried Varnish Films are a source of primary protec tion for surfaces. Exposure to water and dilute alkali solutions are two factors which tend to break down this " protective coating. This test method can be used as a ' comparison basis between manufacturer and consumer to determine the ability of the varnish to resist water and dilute alkali.

Standard Test Methods for Water Vapor Transmission of Organic Coating Films1
This standard is issued under the fixed designation D 1653; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year oflast revision. A number in parentheses indicates the year of Jast reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
These test methods have been approved for use by agencies of the Department of Defense to replace Method 6171 of Federal Test Method Standard No. 141A. Consult the DoD Index ofSpecifications and Standardsfor the specific year ofissue that has been adopted by the Department ofDefense.
1. Scope
i. 1 These test methods cover the determination ofthe rate at which water vapor passes through films of paint, varnish, lacquer, and other organic coatings. The films may be free tarns or they may be applied to porous substrates.
1.2 Two test methods are covered as follows: 1.2.1 Test Method A--Dry Cup Method, and 1.2.2 Test Method B--Wet Cup Method. 1.2.3 Agreement should not be expected between results obtained by different methods. The method that most closely approaches the conditions of use should be selected. 1.3 The values stated in inch-pound units are to be designated as the standard. Metric-inch pound conversion factors are stated in 13.2.1.2 and 13.2.2.2. 1.4 This standard does not purport to address the safety problems, if any, associated with its use. It is the responsi bility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

inch-pound unit is grains per square foot per hour. Accepted SI unit is grams per square metre per 24 h.
3.1.2 water vapor permeance, WVP--the steady water vapor flow in unit time through unit area of a body (WVT) induced by unit vapor pressure difference (Ap) between the two surfaces .of a coating. Therefore, WVP = WVT/Ap. Accepted inch-pound unit is grains per square foot per hour per inch of mercury (called a perm). Accepted SI unit is grams per square metre per 24 h per millimetre of mercury (called a metric perm).
4. Summary of Test Methods
4.1 In Test Method A (Dry Cup Method), the test specimen is sealed to the open mouth of a cup or dish containing desiccant, and the assembly placed in a test chamber with a controlled atmosphere. Two sets of exposure conditions are acceptable for this test method.
4.1.1 Condition A, consisting of 50 % relative humidity at 73F (23C), and
4.1.2 Condition B, consisting of 90 % relative humidity at 100'F (38C).
4.2 In Test Method B (Wet Cup Method), the test specimen is sealed to the open mouth of a cup or dish containing water, and the assembly placed in a test chamber with a controlled atmosphere. Two sets of exposure condi tions are acceptable for this test method:
4.2.1 Condition A, consisting of 50 % relative humidity at 73F (23C), and
4.2.2 Condition C, consisting of very low (near zero) relative humidity at 73F (23C).
4.3 In both methods, periodic weighings ofthe cup or dish are made to determine the rate of water vapor movement through the specimen.
3. Terminology
3.1 Descriptions of Terms Specific to This Standard: 3.1.1 water vapor transmission rate, WVT--the steady water vapor flow in unit time through unit area of a body, between two specific parallel surfaces, under specific condi tions of temperature and humidity at each surface. Accepted

5. Significance and Use
5.1 One of the factors affecting the performance provided by organic coating is the degree of resistance to the passage ofwater vapor. Hence, the water vapor transmission characteristics of coatings are important in assessing their performance in practical use.
5.2 The purpose of these test methods is to obtain values of water vapor transfer through coatings that range in permeability from high to low. These values are for use in design, manufacture, and marketing.
5.3 The water vapor transmission is not a linear function of film thickness, temperature or relative humidity.
5.4 Values of water vapor transmission rate (WVT) and water vapor permeance (WVP) can be used in the relative

jO. Procedure
10.1 Prepare at least three perm cups or dishes for each
test material as follows: 10.1.1 Fill the cups with desiccant to within 'A in. (6 mm)
0f the top edge. 10.1.2 If the cups are equipped with flanges, place the test
specimen between the flanges and adjust the clamps to hold it firmly in position.
10.1.3 If the cups are not equipped with flanges, seal the test specimen to the top edge of the cups with wax as follows:
10.1.3.1 First carefully place the test specimen, cut to the size of the cup, on a thin cardboard ring soaked in molten
wax10.1.3.2 Then place the specimen-covered frame over the
mouth of the cup. Thoroughly seal the flame to the edge of the cup at the temperature to be used in the test. If the coating is on a substrate or support, place the coated side away from the desiccant in the cup.
More 5--Imperfections in the film that are not readily visible, will
produce inconsistent results; consequently make sure that the test is
always run in triplicate.
*"
10.4 Weigh the loaded cups to 1 mg and place them in the lest cabinets or desiccators. Record time, temperature and
relative humidity. 10.5 Remove the cups for periodic weighing to determine
weight gain. Coatings expected to have high WVT ratings, over 10 perms, may require weighings more frequently than
once a day. 10.6 In general, weigh the cups every 24 h for a period of
3 weeks, or until the weight change has become constant. Record the time that weighings are taken to the precision of
approximately 1 % of the time span between weighings. Thus, if weighings are made every day, a time to the nearest 15 minutes would be allowed.
10.7 Shake cups containing desiccant everyday to prevent
surface saturation of the material If moisture absorbed by the desiccant exceeds 20 % of the desiccant weight, discon tinue the test
10.8 Return the cups to the test chamber immediately after weighing.

11. Test Conditions
11.1 Unless other conditions are agreed upon between the purchaser and the seller, perform the test(s) under one or more of the following conditions:
11.1.1 Condition A--Test chamber or cabinet maintained at 73 1F (23 0.6C) and 50 2% relative humidity.
11.1.2 Condition C--Test chamber or desiccator main tained at 73 1F and very low (near zero) relative humidity.
12. Procedure
2.1 Prepare at least three cups for each test material as follows:
2,1.1 Fill the cups with water to within 'A in. (6 mm) of
12.1.2 If the cups are equipped with flanges, place the test specimen over the opening of the cups between the flanges
adjust the clamps to hold them firmly in position. If the
coating is on a substrate or support, place the coated side towards the water in the cups.
12.1.3 If the cups are not equipped with flanges, seal the test specimens to the top edge of the cups with wax in accordance with procedures in 10.1.3.1 and 10.1.3.2.
12.2 Weigh the loaded cups to 1 mg and place them in the test chamber. Record time, temperature and relative hu midity, Follow procedures outlined in 10.5 and 10.6.
12.3 Return the cups to the test chamber immediately after weighings.
13. Calculations
13.1 For each material tested, plot the weight change against elapsed time. When a straight line adequately fits the plot of at least four properly spaced points, a nominally steady state exists and the slope of the straight line is the rate of water vapor transmission.
13.2 Calculate one or more of the following, depending on the water vapor transmission characteristics to be determine
13.2.1 Calculate the water vapor transmission rate, WVT: 13.2.1.1 In inch-pound units as follows:
WVT = (G/t)/A -- grains per ft2 per 1 h
(1)
where: G = weight change, grains (from the straight line), t -- time during which G occurred, h, and A = test area, ft2, 1 g = 15.43 grains.
13.2.1.2 In metric units as follows:
WVT m (G/t)/A -- grams per m2 per 24 h
(2)
where:
G = weight change, g (from the straight line), t = time during which G occurred, h, and A = test area, m2.
13.2.2 Calculate the permeance, WVP: 13.2.2.1 In inch-pound units as follows:
WVP = WVT/4p = grains per ft2 per 1 h per in. of mercury (perms) ' '
where:
4P = S (Hi - R2), S = in. Hg (saturation vapor pressure at test temperature),
(see Table 1), Rl = relative humidity at vapor source; and R2 -- relative humidity at vapor sink.

15. Precision and Bias8
15.1 In an interiaboratory study of these test methods in which one operator in each of three laboratories determined in triplicate the permeance of three coatings covering the range of interest for vapor barrier coatings, the interiaboratory standard deviation for the dry-cup procedure was found to be 0.073 perms with 6 df and the interiaboratory wet-cup coefficient of variation 21.54% relative with 6' df, with no results having been discarded. Based upon these values, the following criteria should be used for judging, at the 95 % confidence level, the accept ability of results:
15.1.1 Repeatability: 15.1.1.1 Test Method A--Two results, each the mean of triplicate runs, obtained by the same operator should be considered suspect if they differ by more than 0.25 perms at dry-cup permeance of less than 1.0 perms. 15.1.1.2 Test Method B--Two results, each the mean of triplicate runs, obtained by the same operator should be considered suspect ifthey differ by more than 74.2 % relative at wet-cup permeances of 5 to 30 perms. 15.1.2 Reproducibility--Intralaboratoiy precision is nor mally better than interiaboratory precision. However, one i participant in this exchange has noted relatively large differ ences when the same coating was tested in quadruplicate! with fairly long intervals between tests. 15.2 Bias is not applicable to these test methods.

6.1 Expose test specimens in accordance with Methods. B 117, B 287, D 1014, D 2803, or any other applicable test method, as agreed upon between the producer and the user. The length of test and evaluation intervals should be agreed upon prior to exposure of specimens.
7. Procedure A--Evaluation of Scribed Specimens
7.1 Method 1 (Air Blow-Off)--Rinse each specimen after completion of the exposure period, using a gentie stream of water at a temperature up to 110T (45C). Holding the nozzle at approximately a 45 angle, blow along the entire scribe line, disturbing the surface adjacent to the scribe mechanically by the air nozzle to ensure an opening for die air blast. Complete the air blasting within 15 min of specimen removal from the exposure cabinet. If the air blasting cannot be completed within the prescribed time, immerse the specimens in water at room temperature dr store in a plastic bag to avoid any drying effect
7.2 Method 2 (Scraping)--Rinse the specimen after com pletion of the exposure period, using a gentle stream ofwater at a temperature up to 110F (45C). Scrape the specimen vigorously with an instrument described in 4.5 while under the gentle stream of the rinse water. Hold the scraper with its face perpendicular to the specimen surface and parallel to the scribe, moving it back and forth across the scribe to remove the coating that has been undercut and has suffered losstof adhesion only, not to remove the coating that still has adhesion. Complete the scraping within 15 min of specimen removal from the exposure cabinet. If scraping cannot be completed within the prescribed time, immerse the speci-

Nwx' 2--Some specimens exposed to natural weathering do not
requite rinsing, air blasting, or scraping to evaluate corrosion. Alterna tive methods may be used ifagreed upon between the producer and the user..
7.3 Rating--Rate the corrosion or loss of paint extending from a scribe mark as prescribed in Table l. Record the representative mean, maxipium, and minimum creepage from the scribe, and note whether or not the maximum is an isolated spot. Also, rate in accordance with Table 2 the prevalence of corrosion on areas removed from the scribe.
8, Procedure B--Evaluation of Unscribed Areas
8.1 Rinse the specimen after completion of the exposure
period (Section 6), using a gentle stream of water at a
temperature up to 100T (40*C). Dry the. jsurface of the
specimen with paper towels or compressed air. Drying
should be done in such a manner that the corrosion on the
specimen surface is not disturbed.
8.2 Evaluate unscribed specimens for corrosion spots,
blisters, and any other types of failure that may occur.
Depending upon the contour of the specimen, the use of a
grid,'as described'in 4.7, is recommended as an aid in
evaluating this type failure (Fig. 1). The percent of surface
failure^ excluding rust staining or run down, can be esti
mated by counting the number of squares that have points of
failure and relating this number to the total number of
squares covering the test area. Discount corrosion within Vi
in. (12.7 mm) of edges.
8.3 Rating--Convert percent failure to th'e rating number
in accordance with Table 2. In some instances, the rating
number may be used as a factor with the corresponding
exposure time intervals to produce a-performance index
number.

1. Scope
1.1 These practices cover four types of treatment for preparation of aluminum and aluminum-alloy surfaces for painting, as follows:
1.1.1 Type A--Solvent Cleaning. 1.1.2 Type B--Chemical Treatments. 1.1.3 TypeC--Anodic Treatments. 1.1.4 Type D--Mechanical Treatments. These four types cover a number of procedures, as described herein. 1.2 Variations in surface treatment produce end condi tions which differ, and which do not necessarily yield identical results when paints are applied. Service conditions will dictate the type of surface preparation that should be selected, although the quality produced by any individual method may vary with different alloys. 1.3 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility ofwhoever uses this standard to consult and establish appropriate safety and health practices and deter
mine the applicability ofregulatory limitations prior to use.
3.1.3 Method 3, Vapor Degreasing, in special equipment employing trichloroethylene vapor, in accordance with Method A, Procedure 2 of Method D 609.
4. Type B--Chemical Treatments

compounds or methods. Selection may be made from available sources,
4.1 Method l. Alkaline Cleaners--Alkaline solutions, such as caustic soda, etch the metal, thus destroying the natural oxide film. They are followed by an acid treatment, preferably nitric acid or phosphoric add. They shall not be used on assembled structures. Inhibited alkaline cleaners are sometimes employed as a pretreatment to remove grease and oil prior to an add treatment. Inhibited alkaline cleaners do not etch the surface. They are not generally recommended unless followed by a conversion treatment, such as described in Methods 4, 5, 6, or 7.

The aluminum surface is converted to a finely crystalline, phosphate coating of the proper texture adapted [0 inhibit corrosion and increase the adherence and dura bility of any applied paint film. It is recommended for product finishes. The phosphate coating process may be carried out by immersion or spray application. The alu minum surface is converted to the phosphate coating by immersion in the processing solution for 30 s to 4 min at 125 to HOT (51 to 60C), or by spraying the solution for 10 s to 2 min at 125 to 160F (51 to 71C).
N' 3--Before applying the treatments according to Methods 4, 5, (, and 7 ofType B, the aluminum surfaces should be freed ofgrease, oil, or other foreign material by means of the procedure described in jdethod 3 ofType A, Method 1 ofType B, or any other suitable method.
N' 4--This treatment complies with the requirements of U.S. federal Specification TT-C-490.
4.5 Method 5, Amorphous Phosphate Treatment--This process comprises treatment of clean aluminum surfaces in a warm (95 to DOT (35 to 54C)) aqueous solution com prising phosphoric, and hydrofluoric acids, chromium trioxide or a solution thereof. The aluminum surface is converted to a thin, adherent, amorphous coating, iridescent green to gray-green in color, depending upon the aluminum alloy treated, which inhibits corrosion and increases the adherence and durability ofapplied paint films. This method is recommended for use under the more severe conditions of service, and for product finishes. The coating process may be carried out by immersion or spray application. The time of treatment will vary from 15 to 45 s for the spray process, and from 30 s to 3 min for the immersion application (see Notes
3 and 5).
N' 5--Most of the treatments conforming to Methods 5, 6, and 7 ofType B comply with the requirements of U. S. Military Specification M1L-C-5541.
4.6 Method 6, Carbonate Chromate Treatment--This process comprises treatment in a hot (180 to 190"F (82 to 88C)) dilute solution of sodium carbonate and potassium chromate for periods from 2 to 20 min, followed by a water rinse. The surface is then given a final treatment in hot 5% potassium dichromate solution, followed by a final rinse. The treatment produces a thin, adherent, conversion coating on the surface, increasing the corrosion resistance of the metal and promoting paint adhesion. This method is recom mended for use under the more severe conditions of service and for product finishes (see Notes 3 and 5).
4.7 Method 7. Amorphous Chromate Treatment--This process comprises treatment of clean aluminum surfaces in aqueous chromium trioxide solutions containing suitable accelerating agents such as fluoride-containing materials. The aluminum surface is converted to an adherent, amor phous, mixed metallic oxide coating, irridescent golden to light-brown in color, which increases the corrosion-resistance and the adherence and durability of any applied paint film. This method is recommended for use under the more severe conditions of service and for product finishes. The coating Process may be carried out by immersion, spray, or brush application, at room temperature (70 to 90F (21 to 32C)), in from 15 s to 5 min contact time (see Notes 3 and 5).
4.8 Method 8, Acid-Bound Resinous Treatment (see Note 6)--This surface treatment involves the use of a suitably
applied add-bound resinous film of approximately 0.3 to 0.5 mils (7.6 to 12.7 pm) thickness. The treatment is based on three primary components: a hydroxyl-containing resin; a pigment capable of reacting with the resin and an acid; and an acid capable of insolubilizing the resin by reacting with the resin, the pigment, and the metal substrate. The alu minum surface should be prepared by Methods 1, 2, or 3 of Type A (see Section 3) or chemical treatments. Type B, 4.1 or 4.2 prior to the application of this treatment. The film may be applied by brush, spray, or dip. Under normal conditions it should dry sufficiently for recoating within 30 min; and within 8 h it should not be softened by organic solvents commonly used in paint coatings. The film has good adhesion to the metal substrate and promotes good adhesion of most subsequent organic coatings to itself. This method is recommended for severe service conditions, particularly on fabricated structures, either in the shop or in the field.
N' 6--^Materials meeting the requirements of U.S. Military Spec ification MIL-P-15328b may be used to apply Method 8 of Type B.
5. Type C--Anodic Treatments (see Note 7)
5.1 Anodic treatment in either sulfuric acid or chromium trioxide electrolyte will provide a protective and inert oxide coating which increases the corrosion-resistance of the metal and promotes paint adhesion. It is recommended where maximum corrosion-resistance by the treatment itself is desired. Anodic treatments should not be used on assemblies of dissimilar metals. The two procedures are as follows:
N' 7--Treatments conforming to Methods i and 2 of Type C comply with the requirements of U.S. Military Specification MIL A-8625.
5.2 Method I, Sulfuric Acid Anodic--This treatment con sists in making the part the anode in a 15% sulfuric acid electrolyte (by weight) and applying current at a potential of about 16 to 18 V and a current density of 12 A/ft2 until desired thickness of coating is obtained. After rinsing in cold water, the coating is sealed for 10 min by treatment in a boiling solution of 5% potassium dichromate. This method is not recommended where danger of acid entrapment is encountered.
5.3 Method 2, Chromium Trioxide Anodic--This treat ment consists in making the part the anode in a 10 weight % chromium trioxide electrolyte at a temperature of 100*F (38C) and applying a potential of40 V for a period of 30 to 60 min. After first rinsing in cold water, the coating is finally rinsed in water at 150F (66C) minimum, and dried; an optional final sealing treatment to obtain maximum protec tion is obtained by immersion in a solution containing 0.01 g chromium trioxide per litre of water (0.0013 or 1 gal) at a temperature of 208 to 212F (98 to 100) for 5 min.
6. Type D--Mechanical Treatments
6.1 Method 1, Hand or Power Wire-Brushing, or other abrasive treatment. Wire-brushing, either by hand or power, roughens the surface of the metal and mechanically im proves the anchorage for superimposed paint films. The disadvantages are that the natural Oxide film on the metal is disrupted and oil or grease films and other foreign matter are not completely removed.

6.2 Method 2, Sandblasting, where employed on. aluminum or its alloys, must be carried out at relatively low pressures and with a fine silica sand. It roughens the surface
and mechanically improves the anchorage for paint films, but destroys the natural oxide film on the metal. Where used, it should be followed by an inhibitive chemical treatment.

Standard Practices for Preparation of Hot-Dip Aluminum Surfaces for Painting1
This standard is issued under the fixed designation D 1731; the number immediately following the designation indicates the year of original adoption or, in the case ofrevision, the year oflast revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.
** N' --Section 2 was added and subsequent sections were renumbered editorially in September 1984.

ethylene vapor. Solvent cleaning does not disturb the natural oxide film on the metal and may prove adequate for some applications.
5. Chemical Treatment
5.1 The surfaces may be prepared for painting by any of the methods for chemical treatment (Note 1) described in 5.2 to 5.9:
N' 1--Materials and procedures employed in these methods of treatment are' available from a number of sources as proprietary compounds or methods. Selection may be made from available sources.
2.1 ASTM Standard: D 609 Methods for Preparation of Steel Panels for Testing
Paint, Varnish, Lacquer, and Related Products2
3. Types of Surface Preparations
3.1 Two types of surface preparations are covered as follows:
3.1.1 Solvent Cleaning, and 3.1.2 Chemical Treatments. 3.2 These two types cover several methods as described in Section 5. Variations in surface treatment produce epd conditions which differ and which do not necessarily yield identical results when paints are applied. Service conditions will dictate the type of surface preparation that should be selected.
4. Solvent Cleaning
4.1 The surfaces may be prepared for painting by any of; the methods for solvent cleaning described in 4.2 and-4.3. , '
4.2 Method 1--Manual swabbing or dip washing with a solvent such as mineral spirits or high flask solvent naphtha. It is extremely difficult to produce a clean metal surface by this method. Accumulated contaminants in the solvent or on the swab are frequently redeposited on the surface being prepared.
4.3 Method 2--Solvent spray cleaning in accordance with Method A, Procedure 1 of Methods D 609.
4.4 Method 3--Vapor degreasing in special equipment in accordance with the latest revision of Method A, Procedure 2 of Method D 609, employing trichlorethylene or perchlor-
5.2 Method 1, Alkaline Cleaners--Etching alkaline solu-.
tions, such as caustic soda, should be avoided because of the
possibility of dissolving away the aluminum coating thereby
exposing the base metal. Since inhibited alkaline cleaners do
not etch the surface, they can be used to remove grease, oil,
and other organic solids from hot dip aluminum. After alkali
cleaning, the surface should be thoroughly rinsed with clean
water. Most often alkaline-cleaned surfaces are subsequently
processed by one of the following methods, described in 5.3
to 5.9:
-
5.3 Method 2, Alcoholic Phosphoric Acid Cleaners--This
treatment involves the use of an aqueous solution of
phosphoric acid with alcohol or other organic solvents,
together with' wetting agents, emulsifying agents, etc. The
solution may be applied by swabbing or dipping (preferably
at a temperature of 70 to 90F (21 to 32C)). The solution
should remain on the surface for several minutes, followed
by thorough rinsing with clean water. A very thin phosphate
film is formed which tends to protect the metal and promote
paint adhesion.
N' 2--Materials meeting the requirements of the latest revision of U.S. Military Specification MIL-M-10578B may be used.
5.4 Method 3, Acid Fluoride Deoxidizer--This treatment includes the use of nitric or sulfuric acid with chromium trioxide and a fluoride. It provides a clean and uniform surface without undue roughening and is effective for removing inorganic soils and any film formed during the
production of the hot dip aluminum. The deoxidizing solution is generally used at a temperature of 70 to 130*F (21 to 54C) (depending on the alloy and the amount of film) and is followed by a water rinse.

5.5 Method 4, Crystalline Phosphate Treatment--This surface-coating method consists in reacting the aluminum surface in a 130 to 145F (54 to 63C) (approximately) zinc acid-phosphate solution containing oxidizing agents and other salts for accelerating the coating action. The aluminum surface is converted to a crystalline, phosphate coating of the proper texture adapted to inhibit corrosion and increase the adherence and durability of any applied paint film. The phosphate coating process may be carried out by immersion or spray application. The aluminum surface is converted to the phosphate coating by immersion in the processing solution for 30 s to 4 min, or by spraying the solution for 10
s to 2 min (Note 3). 5.6 Method 5, Amorphous Phosphate Treatment (see Note
4)--This process comprises treatment of clean aluminum surfaces in a 90 to I25T (32 to 5TC) aqueous solution comprising phosphoric, hydrofluoric acids and chromium trioxide. The aluminum surface is converted to a thin, adherent, amorphous coating, iridescent green to gray green in color, depending upon the aluminum alloy treated, which inhibits corrosion and increases the adherence and durability of applied paint films. The coating process may be carried out by immersion or spray application. The time of treat ment will vary from 15 to 45 s for the spray process and 30 s to 3 min for the immersion application (Note 3).
5.7 Method 6, Carbonate Chromate Treatment (see Note 4)--This process comprises treatment in a 160 to 180T (71
to 82C) dilute solution of sodium carbonate and potassium chromate for periods from 2 to 20 min, followed by a water rinse. The surface is then given a final treatment in a 150 to 160F (66 to 71C), 5% potassium dichromate solution followed by a final rinse. The treatment produces a thin, adherent, conversion coating on the surface, increasing the corrosion resistance of the metal and promoting paint adhesion (Note 3).
5.8 Method 7, Amorphous Chromate Treatment (see Note 4) --This process comprises treatment of clean aluminum surfaces in aqueous chromium trioxide solutions containing suitable accelerating agents such as fluoride-containing ma terials. The aluminum surface is converted to an adherent, amorphous, mixed metallic oxide coating, iridescent golden to light brown in color, which increases the corrosion resistance and the adherence and durability of any applied paint film. The coating process may be carried out by immersion, spray or brush application, at 70 to 130F (21 to 54C), in from 15 s to 5 min contact time. It may be necessary to precede this treatment with a deoxidizer as described in Method 3 (see Note 3).
N' 4--Most ofthe treatments conforming to Chemical Treatment
Methods 5,6, and 7, comply with the requirements ofthe latest revision of U.S. Military Specification MIL-C-5541.
5.9 Method 8, Acid-Bound Resinous Treatment (see Note 5) --This surface treatment is based on the deposition of an acid-bound resinous film of approximately 0.3 to 0.5 mils .. (7.6 to 12.7 jtm) in thickness on the aluminum surface in such a manner as to enhance the adhesion of subsequently applied paint coatings. The treatment is based on three primary components: a hydroxyl-containing resin; a pigment capable of reacting with the resin and an add; and an add capable of insolubilizing the resin by reacting with the resin, the pigment and the metal substrate. The aluminum surface should be pretreated by Solvent Cleaning Methods 1, 2 or 3 or Chemical Treatment Methods 1 or 2 prior to the application of this treatment. The film may be applied by brush, spray, or dip. Under normal conditions it shall dry suffidently for recoating within 30 min; The film has good adhesion to the metal substrate and promotes good adhesion of most subsequent organic coatings to itself.
N' 5--Materials meeting the requirements ofthe latest revision of
U.S. Military Specification MJL-C-15328 may be used to apply to Chemical Treatment Method 8.
The American Society for Testing amt Materials takes no position respecting the validity ofany patent rights asserted In connection with any Item mentioned in this standard.

Standard Practices for Preparation of Magnesium Alloy Surfaces for Painting1
This standard is issued under the fixed designation D 1732; the number immediately following the designation indicates the year of original adoption or, in the case ofrevision, the year of last revision. A number in parentheses indicates the year oflast reapproval. A superscript epsilon (<) indicates an editorial change since the last revision or reapproval.
These recommended practices have been approvedfor use by agencies ofthe Department ofDefense andfor listing in the DoD Index ofSpecifications and Standards.
j. Scope
1.1 These practices cover two classes of treatment for preparation of magnesium alloy surfaces for painting, as follows:
Class I--Chemical Treatments. Treatments.
Class U--Anodic
In general, the latter treatments are the more protective_ of the two classes. Mechanical (abrasive) treatments, solvent cleaning, alkaline solution treatments, and acid pickles not resulting in protective conversion coatings are suitable pre liminary treatments only for metal to be exposed under mildly corrosive (indoor) exposures. When a high degree of corrosion protection and paint adhesion are desired, as in many outdoor environments, surface preparation by one of the above conversion-coat classes is necessary.
N ' 1--Testing of Coatings--Quality control tests of coatings are
frequently desirable, and these generally consist of exposures, with or without paint, to salt spray, humidity, or natural environments, with suitable procedures for assessing the degree of breakdown suffered after fixed time intervals. It is recommended that quality control tests of coatings shall be made as far as possible with high-purity material (for example AZ31A alloy),21the inherent corrosion rate ofwhich is relatively consistent from batch to batch) and that precautions shall be taken to remove surface contamination before coatings are applied. Such con tamination shall be removed by acid pickling to a depth ofat least 0.001
in. (25 pm) per side.
1.2 This standard may involve hazardous materials, oper
ations, and equipment. This standard does not purport to
address all ofthe safety problems associated with its use. It is the responsibility ofwhoever uses this standard to consult and establish appropriate safety and health practices and deter mine the applicability of regulatory limitations prior to use. (See Note 11.)
PRELIMINARY TREATMENT OF SURFACES
2. Procedure
2.1 Certain anodic treatments simultaneously produce conversion coatings on, and remove contamination from, magnesium alloy surfaces. In general, however, apply con
1 These practices are under the jurisdiction of ASTM Committee B-B on
Metallic and Inorganic Coatings. Current edition approved Sept. 8, 1967. Published November 1967. Originally
published as D 1732-60. Last previous edition D 1732-66. 2 For information concerning magnesium and aluminum alloys, see ASTM
Specification B 80, B 90, B 91, B 93, B 107, and B 209 covering these alloys, In the section on Aluminum and Magnesium and Their Alloys, Annual Book ofASTM Standards, Vol 02.02. See also ASTM Practice B 275, for Codification of Certain Nonferrous Metals and Alloys, Cast and Wrought.
version coatings only to surfaces previously freed from all contamination, including oxide, rolling-scale, corrosion product, bumed-on drawing and forming lubricant, and the contamination introduced by blast cleaning and fabrication operations. Contamination in or under surface conversion coatings seriously reduces their protective values (Note 2). For the removal oftenacious surface contamination, such as rolling-scale or casting skin, an acid pickle to dissolve some of the actual surface is essential. When organic contamina tion, such as grease or oil, is also present, an initial degreasing operation in solvent or in an alkaline degreasing solution is usually necessary to allow the subsequent acid to wet the surface. These matters are discussed in more detail under the headings of the specific cleaners or treatments (Note 3), as follows:
2.2 Alkaline Cleaners--Oil, grease, and old (but not baked) chrome-pickle coatings are readily removed by most commercially available heavy-duty alkaline cleaners; but such cleaners are not suitable for removing oxide and the like, for which purpose use acid pickles, preceded by alkaline cleaners. Remove graphite lubricant and also baked chromepickle coatings by a solution conforming to the following composition:
Caustic soda (NaOH) Wetting agent Water (Note 4)
12oz(90g) 0.1 oz (0.74 g) I gal (1 litre)
Soak the parts in the above cleaner for 10 to 20 min at boiling-point, and a treatment shall follow either in the
chromic acid-nitrate pickle described under 2.3.3 or, for parts machined to fine tolerances, in the chromium trioxide solution described under 2.3.1. After alkaline cleaning, rinse in water very thoroughly. Alkaline cleaners may be held in plain steel tanks.
2.3 Acid Cleaners (Note 1)--Acid picking removes millscale, oxide, corrosion product, and the like. Use as a preliminary treatment for surface conversion coatings when the highest degrees of surface uniformity and protective values are required. Add cleaners are as follows:
2.3.1 For Sand and Permanent Mold Castings:
2.3.1.1 Nitm-Sulfuric Acid Solution--Use a solution of 8 volume % of concentrated nitric acid (HNOa) plus 2 volume % Of concentrated sulfuric add (H2S04) in water (see Note 1(a)) at 70 to 90F (21 to 32"C) as a preliminary treatment for new sand tastings arid to remove the surface contaminating effects of blast cleaning. Immerse for about 10 to 15 s, or until 0.002 in. (51 urn) per surface is removed. The solution may be held in ceramic, rubber, synthetic rubber, or vinyl-lined tanks.
221
DUP050297404
D 1732
2.3.1.2 Chromic Acid Solution--Use a boiling 20 weight % solution of chromic anhydride (0rO3) in water to remove old chemical and anodic treatments, corrosion product, and oxide layers, without significant dissolution of metal and hence without changing the dimensions of ma chined parts. Immersion time varies from I to 5 min, depending upon the condition of the surface. The solution may be held in lead-lined steel or ASTM alloy No. 990A or its Aluminum Association equivalent, alloy No. 1100 alu
minum tanks. 2.3.2 For Die Castings: 2.3.2.1 Chromium Trioxide-Nitric-Hydrofluoric Acid So-
lution--This solution is used to produce a smut-free surface
on die castings, without violent attack of the metal. The solution shall conform to the following composition:
Chromium trioxide (Cr03) Hydrofluoric add (60% HF) Nitric acid (70% HN03) Water (Note 4)
37.5 oz (280 g) 1 ft oz (8 ml) 3.25 ft oz (25 ml) to 1 gal (1 litre)
Immerse the parts in the above solution at 70 to 90F (21 to 32C) for 30 s to 2 min, or until a bright, clean surface is obtained. The solution may be held in tanks lined with synthetic rubber or vinyl-base materials.
2.3.3 For Wrought Products: 2.3.3.1 Acetic Acid-Nitrate Solution--This solution rap idly removes surface contamination to 0.001 in. (25.4 pm). Use for wrought parts subsequently to be finished for the maximum protective value. The solution shall conform to
the following composition:
Glacial acetic acid Sodium (NaNCy Water (Note 4)
25.5 fl oz(199 ml) 6.6 oz (49.5 g) to 1 gal (1 litre)
Immerse the parts in the above solution at 70 to 90F (21 to 32C) for 30 s upwards, or until a bright, clean surface is obtained. When heavy surface contamination, such as hot rolled mill-scale is to be removed, immersion times shall be sufficient to remove at least 0.001 in. (25 pm) per surface. The solution may be held in No. 990A aluminum, ceramic,
or rubber-lined tanks. 2.3.3.2 Chromium Trioxide-Nitrate Solution--Use this
solution following the use of the method described in 2.2 for the removal of bumed-on graphite lubricants from hotformed parts. The solution shall conform to the following composition:
Chromium trioxide (Ct03) Sodium nitrate (NaN03) Water (Note 4)
1.5 lb (180 g) 2 oz {15 g) to 1 gal (1 litre)
Immerse the parts in the above solution at 70 to 90F (21 to
32C) for approximately 5 min, for the removal of graphite. 2.4 Abnormally slow reaction in the above solution indi
cates that it is depleted and that the pH has risen to 1.7 or higher. Revivify the solution by the addition of chromium
trioxide to bring the pH back to 0.5 to O.7. Attempt no more than four revivifications. The solution may be held in ceramic, No. 990A aluminum, 18-8 stainless steel, or syn thetic rubber-lined tanks.
N' 2--Removal of Contamination by Welding Fluxes--When a
part to be painted has been welded by an operation involving the use of flux,-such flux shall be removed before the subjection ofthe part to any surface preparation process. Such removal shall be made imniediately by
immersing the part in hot water with scrubbing, and finally by immersing it for 1 b in a boiling 5% solution of sodium dichromate,
after which the part shall be well rinsed.
N' 3: Suspension of Articles for Treatment--The use of magne
sium alloy suspension wires is preferred for use in add pickles in order to avoid objectionable contamination of the solutions through dissolu
tion of the wire materials. Heavy metal contamination, particularly of
copper, may deposit on the magnesium surface and lead to seriously
reduced corrosion resistance. Copper suspension wires in the hot dicbromate solutions are not objectionable.
N' 4: Quality of Water--In the preparation and make-up of acid
pickles, dichromate solutions, and hot-water rinses, precautions shall be taken against the use of water contaminated with heavy-metal impuri ties, or excessive chlorides or sulfates. No upper limits can be specified at this stage for soluble impurities in the water, but powdering of coatings
and poor resistance to corrosion are known to result from the use of contaminated water. Thus, when a choice exists, water from steam condensate or ion-exchange-treated water shall be employed in prefer ence to well water or hard tap water.
SURFACE PREPARATION PROCEDURES--CHEMICAL
3. Class I, Type I (Chrome Pickle)3
3.1 Scope--Class I, Type I treatment is applicable to all formsrand alloys of magnesium except certain special alloys containing silver, but since it may remove as much as 0.0006 in. (15 pm) of metal per surface, it shall not be used on parts machined to fine tolerances. When properly applied, the process constitutes a good paint base, but rigid control is required at each step. The treatment is applicable to magne sium alloy containing inserts of, or attached to, other metals.
3.2 Procedure--For wrought parts the bath shall conform to the following composition:
Sodium dichromate (Na2Cr207-2H20) Nitric acid (HN03) (sp gr 1.42) Water (Note 4)
1.5 lb (180 g) 1.5 pt (187 ml) to 1 gal (1 litre)
3.2.1 For die-, sand- and permanent-mold castings the solution shall conform to the following composition:
Sodium dichromate (Na2Cr307 2H20) Nitric acid (HN03) (sp gr 1.42) SodiUm potassium, or ammonium acid fluoride
(NaHFj, KHF3, or NH4HF2) Water1(Note 4)
1.5 lb (180 g) 1.5 pt (187 ml) 2oz(15g)
to 1 gal (1.0 litres)
For wrought products, sand, and permanent-mold castings
the above solutions operate at 70 to 90F (21 to 32C). The immersion times shall be from 1 to 2 min, the necessary time
increasing with use of the solution. For die-castings give the
parts a 15 to 30 s dip in water at 160 to 180F (71 to 82Q,
followed immediately by a 10-s dip in the second of the above baths, operated at 120 to 140F (49 to 60Q. Failure
to preheat the castings results in no coating in 10 s.
3.2.2 Following immersion remove the parts, allow to drain for not less than 5 s nor more than 30 s, then wash
thoroughly in cold running water, followed by a dip in hot water at 160 to 180"F (71 to 82C) to facilitate drying. Do not allow the parts to drain following the chromate treatment for
more than the specified 30 s; excessive drainage times result in powdery coatings of poor value as paint bases. Such coatings also result from the use of hot-water rinses, the temperatures of which are in excess of 180F (82*Q. Paint the parts preferably immediately after they are dry. The solution may be held in Type 316 stainless steel, or ceramic tanks or in steel tanks lined with synthetic rubber or

pickle. 3.3 Revivification ofSolutions--Sluggish reaction with the
metal, associated with pale yellow, lustrous coatings, indi cates that the solution is depleted. Revivification is accom plished by the addition ofdichromate and nitric acid, to raise tbe dichromate again to 1.5 lb (180 g)/gal (1 litre) and the free nitric acid to levels indicated in the table below. Revivify when the free nitric acid content of the solution is depleted to 0.5 pt/gal (62.3 ml/1 litre) (see Section 11 for analytical
procedure) and shall take place once only for Ml and ZK60A alloys,3 and not more than six times for other alloys ifgood paint-base properties are desired. Excessive use of the solution or too many revivifications result in smooth, lustrous coatings not possessing the degree of etch necessary for the best paint adhesion with conventional primers. Revivify in accordance with the following table:

4. Class I, Type II (Sealed Chrome Pickle)4 5 *
4.1 Scope--Class I, Type II treatment is applicable to all types and forms of magnesium-base alloys, subject only to the limitations of the Class I, Type I treatment, since it is essentially the same process as the latter, followed by sealing. In protective qualities and as a paint base, this treatment is somewhat superior to that of Class I, Type I treatment under severe exposure conditions (Note 5).
4.2 Procedure--Following chrome pickling as specified under Section 3 and rinsing in cold water, transfer the parts immediately to a boiling solution conforming to the fol lowing composition:
Sodium dichromate (Na2Cr207-2H20) Calcium or magnesium fluoride (CaF2 or MgF2) Water (Note 4)
1.5 lb (180 g) 'h oz (2.5 g) to 1 gal (1.0 litre)
Boil the parts in the above solution for 30 min, after which rinse them in cold running water, followed by a rinse in hot water at a temperature of not less than 160"F (71C) nor more than 180F (82C) to facilitate drying. Preferably apply the paint coating immediately after the parts are dry. The solution may be held in a steel tank.
N' 5: Causes ofDefective Coatings--The following information is
intended to provide guidance on the causes of the most usual defects arising in the application of either Class I, Type I or Class I, Type n coatings:
(a) Spotted Coatings are caused by ineffective preliminary degreasing or by the presence ofexcessive surface contamination not removed prior
to or during the chrome pickling treatment, or both. (b) Nonadherent Powdery Coatings are caused by: (/) Too long an interval between removal from the chrome pickle
and rinsing, (2) Ratio of acid to sodium dichromate too high, (J) Temperature of the solution or of the hot-water rinse too high. (4) Metal improperly degreased, or (5) Solution revivified too many times.
5. Class I, Type IIIs
5.1 Scope--Class I, Type III treatment is applicable to all types and forms of magnesium-base alloys except Ml alloy2 and certain rare-earth alloys similar to EK30A.2 It produces in itself no appreciable dimensional change and is, therefore, applicable to parts machined to fine tolerances. The treat ment is applicable to magnesium containing inserts of, or attached to, other metals, but in such cases the preliminary treatment (5.2) shall be in the bifluoride bath (Solution No. 2) described in 5.2.2.
N' 6: Causes ofDefective Coatings--The following information is
intended to provide guidance on the causes of the more usual defects arising in the application of coatings from the Class I, Type III treatment.
(a) Nonadherent Powdery Coatings are caused by: (1) Over-dilution ofthe hydrofluoric acid or acid fluoride solution, (2) Low pH (less than 4.0) of the dichromate solution, (3) Insufficient precleaning of the metal surface, and
(4) Direct contact between the steel tank containing the dichromate solution and the article being treated. (b) Failure to Coat and Nonuniform Coatings are caused by:
(1) High pH of the dichromate solution, (2) Low concentration of the dichromate,
(i) Insufficient precleaning.of the metal surface, (4) Omission of fluoride treatment, (5) Use of an unsuitable alloy for die treatment, for instance, Ml alloy,
(0) Excessive immersion time in the hydrofluoric add solution or use of an H2F2 concentration in the dichromate solution in excess of
0.2%,
(7) Insufficient rinsing after the hydrofluoric acid dip, and (8) Insufficient heating of the dichromate solution (minimum temperature shoud be 200F (93C)).
5.2 Procedure--Following cleaning as prescribed in Sec tion 2, treat the parts firsi by immersion at 70 to 90T (21 to 32C) in one or other of the following solutions:
5.2.1 Solution No. I:
Hydrofluoric acid (60% H2F2) Water (Note 4)
24 fl oz {187 raJ) to l gal (1 litre)
5.2.2 Solution No. 2:
Sodium, potassium, or ammonium acid fluoride (NaHF2, KHF2, or NH4HF2)
Water (Note 4)
6% oz (50 g) to i gal (1 litre)
Solutions No. 1 and No. 2 may be held in tanks consisting of steel lined with lead or rubber. In solution No. 1, immerse AZ31A and AZ31B alloy parts3 for from 30 s to 1 min; immerse all other alloys for 5 min. In solution No. 2, immerse all the alloys for 5 min. Solution No. 2 is suitable for use with all forms of magnesium alloys except those castings which have not been acid-pickled after blasting; these castings shall be treated in the hydrofluoric acid solution (solution No.- 1). Following one or other of the
above treatments, the parts shall be rinsed thoroughly in cold running water and transferred to a solution conforming to the following composition:
Sodium dichromate (Na2Cr207-H20) Calcium or magnesium fluoride (CaF2
or MgF2) Water (Note 4)
1 to 1.5 lb (120 to 180 g) 'h oz (2.5 g)
to 1 gal (1 litre)
4 Conforming to Class 1, Type II treatments are the AMC "L" process, the Dow No. io process, and Type II treatment of Military Specification MIL-M-3171A.
5 Conforming to Class 1, Type III treatments are the AMC "G" process, the Dow No. 7 process, and the Type III treatment of Military Specification
MIL-M-3171A.

. Operate the above solution at boiling point and immerse the
parts therein for 30 min, following which thoroughly rinse
them in cold running water, followed by a hot-water dip to facilitate drying. Preferably, apply the paint coating as soon as possible thereafter. A mild steel tank is suitable for holding
the above solution. 5.3 Maintenance ofSolutions: 5.3.1 Fluoride Solutions--Keep the concentration of free
hydrofluoric acid in the solutions of 5.2.1 and 5.2.2 constant by the addition, as required, of either hydrofluoric acid or acid fluoride, respectively. See Section 9 for the analytical
procedure. 5.3.2 Dichromate Solution--Keep the pH of the
dichromate solution within the limits 4.0 to 5.5, or 4.0 to 4.8
in the case of AZ31A or AZ31B alloy,2 by addition of chromium trioxide as required. Maintain the level by the addition of water. Maintain the solution saturated with respect to either magnesium or calcium fluoride by contin uous immersion of a cloth bag containing excess of one or
other of these compounds.
SURFACE PREPARATION PROCEDURES--ANODIC
6. Class II, Type I (Galvanic Dichromate Treatment)6
6.1 Scope--This treatment produces black coatings of good protective and paint-base qualities, and is applicable to all alloys and forms ofmagnesium, including Ml alloy,2 with or without attachments of other metals. No appreciable dimensional change results, and hence the treatment is also applicable to articles machined to fine tolerances.
6.2 Procedure--Following cleaning as prescribed in Sec tion 2, treat the articles in fluoride solution No. 1 or No. 2 as prescribed in 5.2. Use the latter solution when other metals are attached to the magnesium. After rinsing, immerse the articles in a solution conforming to the following
composition:
Ammonium sulfate {(NH4)2S04) Sodium dichromate (Na2Cr207 2H20) Ammonia (NH4OH) (sp gr 0.880) Water (Note 4)
4 oz (30 g) 4 oz (30 g) Vi 0 oz (2-d ml) 1 gal (1 litre)
Operate the above solution at 120 to 140F (49 to 60C). The articles shall be made the anodes in the solution, with the tank, if of mild steel, acting as cathode, or with separate steel cathodes if the tank is lined with nonmetallic materials. No separate generator is necessary,- but the magnesium parts must be electrically connected with the tank, or with the separate cathode plates through an external connection, taking care that the parts do not make direct contact with the cathode material.
6.2.1 The time of treatment shall be such that a uniform black coating is obtained on the articles. This takes from 10 to 30 min, and the consumption of from 70 to 150 A min/ft2 (929 cm2). An anodic current density of not more than 10 A/ft2 (929 cm2) is desirable.
6.2.2 Following the treatment, rinse the parts thoroughly in cold running water, followed by a hot-water dip to facilitate drying.
.6.3 Maintenance ofSolutions: 6.3.1 Fluoride Solutions--Maintain the fluoride solutions
as under 5.3.1. See Section 9 for the analytical procedure. 6.3.2 Sulfate-Dichromate Solution--Maintain the pH of
this solution between 5.6 and 6.2 by periodic additions of a solution containing 5 weight % of both chromic anhydride (Cr03) and concentrated sulfuric acid (H2S04, sp gr 1.84).
7. Class n. Type II7
7.1 Scope--This treatment is applicable to all forms and alloys of magnesium. Many aluminum alloys will anodically polarize in the treatment solution, and hence magnesium parts with aluminum attachments or inserts can be anodized. With aluminum alloys containing copper, however, the coating of the magnesium will proceed only if the area of the aluminum alloy is small compared to that of the magnesium. Metals other than aluminum or its base alloys shall not be in contact with the magnesium.
7.2 Coating Properties--The anodic coating consists of two phases: the first-formed phase is greenish-tan in color and about 0.0002 in. (5 pm) thick; whereas the second phase, -formed only at higher voltages following the production of the tan coating, is fused and vitreous in nature, dark-green in color, and of thickness about 0.0012 in. (30 pm), causing a dimensional increase of about 0.001 in. (25 pm) per surface. The corrosion-resistance and paint-base characteristics are similar, and excellent for both the above phases. The coating possesses high abrasion resistance, but spalls under compression deformation. The dark-green coating can be partially impregnated with low-viscosity, penetrating, or ganic coating materials, a procedure that considerably re duces its spalling tendency.
N' 7--The dark-green coating of Class II, Type II treatments is
recommended in preference to the thin tan coating only when: (a) Preliminary removal of surface contamination is not convenient. (b) The highest degree of abrasion-resistance is required from the
coating. (c) A dimensional increase (see above) can be tolerated. (d) The article will not be subjected in service to impact, deformation,
or flexing likely to cause spalling of the coating.
7.3 Procedure--The thin tan coating is formed with a current consumption and in a time approximately one quarter of that required to form the dark-green coating. The latter forms only after the voltage across the solution has reached the spark potential. During the ensuing coating formation, surface contamination, including graphite, is concurrently removed. Thus, articles intended to receive the dark-green coating need not first be cleaned. On the other hand, the formation of the thinner tan coating does not concurrently remove surface contamination. Since such contamination can seriously reduce corrosion resistance, it is mandatory that a preliminary cleaning, including acid pick ling (2.2) shall be given to articles intended to receive the lower-voltage tan coating.
7.3.1 Rack and clean parts as appropriate (see above), and anodize either by direct or alternating current in an electro lyte conforming to one of the following compositions, respectively:
6 Conforming to Class II, Type I treatment are the AMC "K." process, the Dow No. 9 process, and Type IV treatment of Military Specification MIL-M-3171A.
7 Conforming to Class n. Type II treatment is the Dow No. 17 process.

rte temperature of the solution shall preferably be from [60F to I80F (71 to 82C). It will not operate below 140F
0'C), but temperatures higher than 180F (82'C) do not Jjgleteriously affect the results. After anodizing rinse the parts jn running cold water, followed by a short immersion in hot water, or by treatment with hot air, to facilitate drying, preferably, apply the paint coating immediately after the
parts are dry. 7.4 Power Requirements--A current consumption of
from 50 to 500 A-min/ft2 (929 cm2) is necessary, according to both the composition of the alloy being treated and the type of coating desired. Thus, in the case of the dark-green coating on AZ31 alloy, for a 10-min treatment with alter
nating current, a current density of 30 A/ft2 (929 cm2) is applied; but greater or lesser currents may be utilized by. varying the time of treatment as, for example, application df 50 A/ft2 (929 cm2) for 6 min. On the other hand, for the same alloy, the thin tan coating may be applied with alternating current, with a current consumption of 75
A-min/ft2 (929 cm2), equivalent to a treatment time of only 1% min at 50 A/ft2 (929 cm2). As the coating forms, the resistance of the circuit increases, and consequently the voltage must be increased to maintain a constant current density. Normally the voltage across the bath will reach from 75 to 95 for the dark-green coating (according to alloy composition) and from 60 to 75 for the thin tan coating. In carrying out the treatment, a constant current control is a considerable advantage, inasmuch as the total treatment time can be preset and manual control of the voltage and current then become unnecessary.
7.4.1 As guides to the current consumptions with various alloys, some data are presented in Table 1. It will be appreciated that rigid current consumptions in the formation of the thin tan coating cannot be specified, since this coating can be varied in thickness considerably between say 0.0001 in. (2.5 pm) and 0.0005 in. (12.7 pm), and still be formed below the critical spark potential at which the dark-green vitreous coating begins to develop.
7.5 Solution Control--With depletion of the bath upon use, the final voltage required to impress the above currents on the article will slowly rise, but even for the full green coating at least 20 ft2 (50 dm2) of surface can be treated per

gallon (1.0 litre) of solution before any change in the final voltage is experienced; and up to 40 fit2 (98 dm2)/gal (1 litre) can be treated before revivification of the solution becomes necessary.
7.5.1 Prior to revivification, analyze for dichromate and phosphoric acid (see Sections 10 and 12), and make up differences from the original composition by additions of sodium dichromate and phosphoric acid.
7.5.2 A simple method for the determination of fluoride in the solution is not yet available. The fluoride concentra tion, however, is not critical, provided it always exceeds minimum concentration, below which pitting of the articles may ensue during their treatment. When revivifications are made by additions of sodium dichromate and phosphoric acid, make a concurrent addition of ammonium acid fluo ride, equal to three times the weight of sodium dichromate added. Secondly, if pitting of the articles should occur under treatment; it is an indication that the fluoride content of the solution is too low, and about 5 oz (38 g)/gal (1 litre) of ammonium" acid fluoride shall then be added in order to relieve the trouble.
7.6 Tank and Rack Materials--Mild steel is suitable for tanks and heating coils. Other metals, such as copper, aluminum, lead, zinc, Monel, and stainless steels are at tacked by the electrolyte. When direct current is used the tank itself can be the cathode, but, when alternating current is used, at least two magnesium parts are necessary, of area ratios not more than 3 to 1, each one serving as electrode. The articles shall not contact the tank, otherwise pitting will ensue.
7.6.1 Racks shall be normally made of magnesium alloy, but aluminum alloys containing magnesium, such as ASTM alloy No. GR20A, or its Aluminum Association equivalent, alloy No. 5052, can be used if desired, provided they are not allowed to be in the solution on open circuit. Use a spring clip with magnesium ends for providing contact with thin sheet material, the liquid level not being allowed to extend beyond the limit of the magnesium ends of the clip. No solution-line attack is experienced on magnesium. Magne sium racks may be stripped by immersion for 2 min- in hot 20% chromium trioxide solution or by immersion at room temperature for about 8 miri in the chromium trioxidenitrate solution bath described in Section 2.2.3.
8. Class II, Type HI8
8.1 Scope--This treatment is-applicable to all forms and alloys of magnesium, free from attachments or inserts of other metals.
8.2 Coating Properties--The anodic coating consists of two phases; The first-formed subcoating phase is a light tan in color, and causes a dimensional increase of about 0.0002 in. (5 fim) per side; the second and thicker phase, formed at higher voltages, is dark brown and causes a dimensional increase offrom 0.001 in. to 0.0012 in. (25 pm to 30 pm) per surface. The paint-base characteristics are similar, and excel lent for both the above phases.
8.2.1 The dark-brown coating is hard and highly abrasionresistant, but it spalls under compression deformation and its
8 Conforming to Class 11, Type III treatment is the HAE process.

formation can cause a loss of fatigue strength of the metal.
Such loss is negligible with metal erf thickness 0.1 in. (2.5 mm) or over, rising to 3% and 9% for thicknesses of 0.094 in. (2.4 mm) and 0.040 in. (1 mm), respectively, all under reversed bending and corrected for coating thickness. No loss of fatigue strength arises from application of the thin tan coating* and neither is this coating subject to spalling.
8.3 Procedure--Rack and clean with hot alkaline cleaner (2.1) or chromium trioxide (2.2.1), or both, as appropriate, and anodize with alternating current in an electrolyte con forming to the following composition:
Potassium hydroxide (KOH) Aluminum hydroxide (AI(OH)3) soluble in hot
KOH solution (Note S) Potassium fluoride (K2F2j Trisodium phosphate (Na3P04) Potassium manganate (K3Mn04) (Note 9)
Water (Note 4)
IS to20 oz(135 to 150 g) 4 oz (30 g)
4.5 oz (34 g) 4.5 oz (34 g) 2.5 oz (19 g) to 1 gal (1 litre)
Dissolve the constituents of the electrolyte in the above order. Maintain the temperature of the electrolyte between 77 and 100F (25 to 38C).
N' 8--If an exceptionally hard, abrasion-resistant dark-brown
coating is desired, the aluminum hydroxide in the above electrolyte shall
be increased to 6 to 7 oz (45 to 52 g)/gal (1 litre).
N' 9--Potassium manganate (K2Mn04) in the above electrolyte
may be replaced with an equal weight of potassium permanganate (KMn04), but in such case the permanganate shall be completely
dissolved in water before it is added to the solution and an additional 1 Vi oz (11 g) of potassium hydroxide shall also be added. During operation
of the bath, the permanganate is slowly reduced to manganate, complete conversion taking place after a metal area of approximately 2 ft2 (18.6
dm2)/gal (1 litre) of electrolyte has been treated.
8.4 Post-Treatment--After the electrolytic treatment, rinse the parts well in water and immerse for 1 min at room temperature in a solution consisting of 2.7 oz (20 g) of sodium dichromate (Na2Cr207*2H20) and 13.3 oz (99 g) of ammonium bifluoride (NH4HF2)/gaI (1 litre) of solution. Following the immersion, remove the parts and dry without rinsing. Paint at any convenient time after the parts have
dried. 8.5 Power Requirements--The practical range from cur
rent density is from 15 to 20 A/ft3 (9.3 dm2) with voltages rising to from 70 to 86 (depending on alloy) for the hard brown coating and to 58 V for the thin tan coating. In this current density range, the terminating voltage is reached in from 45 to 60 min for the hard brown coating and in 10 min or less for the thin tan coating. Raise the voltage quickly from zero to 40 or more, and adjust the current and retain at the density desired. Normally the voltage will rise to 55 or more within 1 min, but as the coating forms, the resistance of the circuit increases and the voltage must be raised continu ously to maintain the desired current density;
N' 10--If, at low initial voltages, the current remains high and
coating formation does not proceed, a "surge" current shall be imposed by rapidly raising the voltage to 40, followed by immediately lowering it to zero. The voltage shall then be adjusted in the normal manner to maintain the desired current density.
8.6 Solution Control--The operating life of the electrolyte is extremely long, and under normal conditions of use it need never be discarded. Manganate and aluminate deplete slowly with use, whereas the depletion of fluoride and phosphate is extremely slow.
8.6.1 In the case ofthe dark-brown coating, a lightening of i
the normal color indicates a depletion of manganate in the 1 5solution, and additions shall then be made of 1 oz (7.5 g) of 1 ar
potassium manganate plus 1% oz (11 g) of aluminum I jyl
hydroxide for each gal (1 litre) of solution. Add the alu- 1 to minum hydroxide after first dissolving it in a solution 1 SO
containing a weight of potassium hydroxide equal to that of 1
the aluminum hydroxide to be added
1 in
8.6.2 A rough coating indicates either a low, or an 1 in
excessively-high, alkalinity in the electrolyte. The alkalinity [ bt shall be maintained between 10 and 12% free KOH, as * tb
determined by the method described in Section 13.
I
8.7 Tank and Rack Materials--Plain black iron is suit- | 11
able for tanks and cooling coils. Suspend the parts by | magnesium-base alloy clips or the like and protect them at f lo
the solution level by electroplaters' vinyl tape. Magnesium racks may be stripped of coating when necessary by immer
T re
sion in hot 20% chromium trioxide solution (Note 11).
8.7.1 Divide parts to be treated into two batches each of
l:
approximately the same surface area. Rack each of the
ct
batches and connect electrically to one or other of the inlet
Pl
terminals of the power supply so that the magnesium parts
li-
constitute both electrodes of the electrolysis bath (Note 12).

N' 11: Safety Precautions--Consideration should be given to the :
health hazards associated with the procedures covered by this specifica
tion. Precautions must be taken to avoid skin contact with any of the
solutions involved, and to avoid inhalation of vapors, fumes, or spray j
arising thereform. Baths containing dichrotnate or fluoride shall be fitted !
with exhausts to remove all spray arising therefrom.
j
N' 12: Repair Treatments--Pretreatment films that have been !
damaged shall be repaired before painting. Repair shall be effected by '
one of the treatments below. The phosphate touch-up solution of 8.2 -
below necessitates special preparation, whereas a chrome pickle solution |
is often already available. Nevertheless, for brush-on treatment, the - :
phosphate solution possesses the advantages of being nontoxic and
nonirritant. `

The treated surface shall then be thoroughly flushed with water and,
when dry, rubbed vigorously with a clean dry rag to remove loose
powdery matter which, if allowed to remain, would deleteriously affect
the adhesion of superimposed paint.

aPP^the concrete or "asonry mix. 5.9 Allow the bond-coated panel to stand overnight (min
imum).
6. preparation of Concrete Panels
6.1 In the mixing box, prepare the concrete, from 1 part 0f portland cement and 3 parts of sand by volume. Thor oughly mix these dry ingredients. Add water and mix thoroughly. Use only enough water to make the mortar sufficiently plastic as to be easily worked into the comers of the form.
jjC N' 2--Using dry ingredients, a good portland cement concrete mix may be obtained by using sufficient water to give a ratio between weight ofwater and weight ofcement ofapproximately 0.6 (0.1) to 1.0.
6.2 Place the previously coated shingle or sheet, coatedside up, within the forms. Place the wet concrete in the forms on top of the coated base with the steel trowel, work the mixture into the comers and next to the form. Strike off the top with a wooden screed and use a wooden or cork float or trowel to level offthe surface and work to the desired texture. Finally, brush the surface evenly with the dry paint brush.
N' 3--IF deemed desirable, the surface of the bond-coated base
may be wetted prior to placing the concrete mix. If this is done, the water-cement ratio should be reduced to compensate, otherwise a wet and sloppy mix may result.
6.3 During the first hour of the setting period, gas may form between the bond coat and the concrete coat, causing bubbles to form upon the surface of the panel. These should be broken carefully or punctured by a slender, sharp instru ment to permit the gas to escape. Any holes thus made may be smoothed over, or filled up, about an hour later.
6.4 After the concrete has set up sufficiently to permit removal of the forms from the panel, or the panel from the forms, smooth the edges to desired texture, and cover with a wet cloth.
6.5 Keep the panel covered with the wet doth until seasoned to desired age, wetting the cloth thoroughly twice daily. To provide freedom from crazing or cracking, a minimum seasoning period of seven days is recommended.
6.6 Before using, bevel off top exposed edges with a carborundum stone, sufficiently to prevent edge-breakage in use. '
7. Preparation of Masonry Panels
7.1 In~the mixing box, prepare the masonary or stucco mix from 1 part of Portland cement, 1 lA parts of masonry cement, and 3 parts of sand, by volume. Thoroughly mix these dry ingredients. Add water and mix thoroughly. Use only enough water to make the mortar suffitiently plastic as to be easily worked into the comers of the form.
N' 4--The addition ofmasonry cement to the stucco mix makes a
more workable mix than using only portland cement, and the watercement ratio may be reduced to 0.5 (0.1) to 1.0.
7.2 Proceed as described in Section 6.2 to 6.6.
8. Identification
8.1 Identify the back of each panel (shingle or asbestos cement sheet side) as to type of mix (concrete or masonry) and data of manufacture.
N' 5--For optimum reproducibility, panels used in the same test
should be of the same age, cure and seasoning.

3. Summary of Practice
3.1 Coated specimens are placed in an enclosed chamber where a water fog is sprayed on them. The temperature ofthe chamber is usually maintained at 100F (38C). The expo sure condition is varied by selecting the duration of the test. Water permeates the coating at rates that are dependent upon the characteristics of the coating. Any effects such as color change, blisters, loss of adhesion, softening, or embrittlement are observed and reported.

4.2 Water fog tests are used for research and development
closed unit
of coatings and substrate treatments, specification accep
tance, and quality control in manufacturing. These teste
usually result in a pass or fail determination but the degree of
failure may also be measured. A coating system is considered ;
to pass if there is no evidence of water-related Mure after a
specified period of time.
4.3 Results obtained from the use of water fog tests in
accordance with this practice should not be represented as
being equivalent to a period of exposure to water in the
natural environment, until the degree of quantitative corre
lation has been established for the coating or coating system.
4.4 The test apparatus is identical to that used in Method
B 117, and the conversion of the apparatus to water fog
testing is not difficult. Corrosion tests of a scribed coating on
a ferrous substrate are possible as the water that drips off of |
the specimens is not recirculated.

s#t)Strates are given in Methods D 609 and Practices D 1730. Test Methods D 823 cover application techniques of the production of [inform films.
j. Procedure
7.1 Fill the reservoir with reagent water conforming to fype III of Specification D 1193.
7.2 Maintain the test chamber at a temperature of 100 2"F (38 1C). Other temperatures may be used if the temperature is reported in Section 8.
7.3 Support or suspend specimens approximately 15 from the vertical with the plane of the specimen parallel to tfre direction of fog flow. Slotted wood supports are suitable for flat specimens. Provide for free settling of fog on all specimens. Space specimens so that they do not touch each other, any metallic material, or any material capable of acting as a wick. Arrange the specimens so that water from one specimen does not drip on other specimens.
7.4 Place two containers within the chamber to collective fog for measurement. Locate one container near the fog nozzle with the other as far as possible from the nozzle and place them so that they collect only the fog from the nozzle. Glass funnels with the stem extending into graduated cylin ders or dishes having a diameter of 100 mm are recom mended.
7.5 Adjust the atomizing air supply so that 1.5 to 3.0 mL of water/h is collected , in a collector with a diameter of 100
mm.
N' 3--The fog rate specified in Method B 117 is only 1.0 to 2.0
mL/h for a collector with a diameter of 100 mm.
inspect or remove specimens or to replenish the water supply are permitted.
7.7 Conclude the test after a specified period of time or after effects from exposure to water fog are observed. > 7.8 Wipe the test specimens dry. Rate specimens for changes in color, blistering, etc. Evaluate specimens no less than 5 min and no more than 10 min after removal from test, as the effects from water exposure can change within a short time. Remove only as many specimens as can be rated within the specified time.
N' 4--The 0 to 10 scale described in the ASTM STP 5007 is
preferred for rating. Relevant procedures for evaluating water effects are described in Test Methods D 610, D 714, D 2616, D 3359, and D 3363.
7.8.1 If possible, rate the specimens again after they have been removed from the test for a recovery period long enough that moisture absorbed within the specimens dries out and the specimens reach moisture equilibrium with room air. A recovery period of 12 from 24 h is generally sufficient.- The post-recovery rating allows evaluation of the permanent effects of the exposure as distinct from the transient effects, and is especially important for evaluation of color and gloss.

JO. Procedure
This standard is issued under the fixed designation D [ 736; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (c) indicates an editorial change since the last revision or reapproval.
1. Scope 1.1 This test method covers the determination of the
tendency of an interior wall paint to effloresce under normal environmental conditions. Historically this phenomenon has been exhibited primarily with latex, or other water-based paints, and the method has been used in testing aqueous products.
1.2 This test method is limited to the determination of the efflorescence resulting from migration of soluble salts from within the paint film. It does not deal with the efflorescence attributable to certain substrates.
1.3 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Descriptions of Terms Specific to This Standard: 3.1.1 efflorescence--a condition that occurs when soluble salts in the dried paint film or in the substrate migrate to the film surface during exposure. It should not be confused with other causes of nonuniform appearance or whitening that may occur at the time of application. Efflorescence is seen as either a light, medium, or heavy deposits of crystals. It exists both in isolated patches and over wide areas. Another evidence of efflorescence is the development of a nonuniform appearance of flat or glossy areas during the cycling procedure of the test. 3.1.2 degrees ofefflorescence: 3.1.2.1 flatting and glossing--A nonuniform decrease or increase in gloss noticeable when the surface is illuminated and viewed at near grazing angles. There is no apparent change in color when viewed perpendicularly to the surface. 3.1.2.2 fine efflorescence--A barely discernible whitening of the surface when viewed perpendicularly. 3.1.2.3 medium efflorescence--A readily noticeable whit ening of the surface without a marked masking of the color.

4. Summary of Test Method
4.1 Painted panels are exposed to controlled cycles of low temperature and high humidity, and to standard conditions of temperature and humidity, inducing a fine condensate on the surface. The test is run for a maximum of eight cycles.
f
5. Significance and Use'
5.1 TJie test conditions are similar to conditions that produce efflorescence inside a home or building. The degree of efflorescence and the number of cycles required to produce it are a good indication of the paint's ability to resist efflorescence.
6. Apparatus
6.1 Test Cabinet--A cold-wall type of household refriger ator without exposed cooling coils. Additional humidity shall be introduced into the test area from a pan of water on the chamber floor, or by putting water in the butter conditioner and setting die conditioner at its highest temperature. Conditions in the test cabinet shall be maintained at 42 3F (5.5 1.5Q and at 75 to 80 % relative humidity. Any other type of cabinet, used should be checked for reproduc ibility of. test results by comparison with a recommended cabinet.
i
7. Reagents
7.1 Purity of Water--Unless otherwise indicated, refer ences to water shall be understood to mean reagent water as defined by Type IV of Specification D 1193.
8. Test Panels <>
8.1 A sealed substrate shall be used. One satisfactory surface is tempered hardboard sealed with one coat of shellac varnish (3 to 4-lb cut). The panel size shall be 6 by 18 in. (150 by 450 mm). If the panel does not fit the cabinet, the size may be changed, although the area should be kept approximately the same.
9. Preparation of Panels
9.1 Apply the shellac varnish to the test panel and allow to dry. Brush two coats of the test paint on both sides of the sealed panel. Apply the test paint at a temperature above 60F (15.5Q and allow approximately 1 h between coats or, if not a latex paint, allow an appropriate time for drying between coats. After applying the second coat, dry the panel for 1 h (or appropriate time) at the same temperature and observe for uniformity of appearance at all angles of viewing before placing in the test cabinet If the panels are

(P procedure
jO.l Hang the panels vertically in the test cabinet with a cing of 1 to 2 in. (25 to 50 mm) between them and chill 23 h. Then place them in a room at approximately 77F LoC) and 50 % relative humidity until the surface is dry approximately 30 min). ' 10.2 Inspect for efflorescence by observing the panels at 85* angle of incidence to a light source so that any change . surface appearance can readily be noted. 1 10.3 Return the panels to the test cabinet at 42F (5.5"C), UP % relative humidity for '/> h to chill before receiving a jteam treatment as follows: 10.3.1 Heat Vi in. (13 mm) deep reagent water in a Oat-bottom pan to boiling. Remove or reduce the heat until (Here is no bubbling. 10.3.2 Remove the panel from the cabinet and hold it over the pan until afine condensate forms on the surface. As" soon as the fine condensate covers about 75 % of the panel area return the panel immediately to the test cabinet. It should take only a few seconds to develop the condensate, and the panel should be replaced in the test cabinet in less than 5 to 10 s.
N' 1--Place the steam apparatus as near as possible to the test
cabinet. The panel temperature will rise quite rapidly and will interfere ^jlh the formation and retention of condensate if the panel is out of the test cabinet too long. Formation of too large a condensate droplet will
cause water spots or rundown streaks and interfere with the develop ment and rating of efflorescence.
10.4 Subject the panels to eight cycles, unless heavy efflorescence is observed in fewer cycles. The 23 h in the test cabinet followed by conditioning at standard temperature and humidity and by observation of the panels constitute the first cycle; the steaming, 23-h chilling, conditioning, and observation constitute subsequent cycles, with exposure in the test cabinet over the weekend constituting one test cycle. Start the test on Monday or Tuesday so that only one weekend cycle is included in the test series. Other end points may be established by agreement between the purchaser and the manufacturer.
11. Report
11.1 Report any glossing, flatting, light, medium, or heavy efflorescence, and the percent of the surface covered. When heavy efflorescence occurs in fewer than eight cycles, report the number of cycles required to produce this condition.
12. Precision
12.1 This test method was developed to provide a reliable qualitative and semiquantitative measure of efflorescence. Available information on the method is not sufficient to establish its reproducibility on a quantitative basis, so that a statistical statement of precision is not possible. However, the need for other than a reliable qualitative or semi quantitative rating is not apparent at this time; further studies will be undertaken if the need arises.

Standard Test Method for Print Resistance of Architectural Paints*1
This standard is issued under the fixed designation D 2064; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year oflast revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<) indicates an editorial change since the last revision or reapproval.
j. Scope 1.1 This test method covers an accelerated procedure for
evaluating the print resistance of architectural paints. It differs from print resistance Test Method D 2091 in that the latter is concerned with lacquer finishes under packaging, shipping, and warehousing conditions, whereas this test method is concerned with decorative coatings undergoing mndom on-site pressure contact.
N' 1--Printing should not be confused with blocking, which is
measured in Test Method D 4946. The former relates to the indentatjon 0fa surface, and the latter, the sticking together of two surfaces. *"

3. Terminology
3.1 Definitions: 3.1.1 print resistance--the ability of a paint film to resist forming a permanent impression in a semihardened film as a result of a pressure from an object placed on it. 3.2 For additional definitions of terms, refer to Paint/ Coatings Dictionary}
4. Summary of Test Method 4.1 A piece of cheesecloth is placed on the painted surface
and topped with a No. 8 rubber stopper (position smaller diameter of stopper on the cheesecloth) and a 500-g weight to create a pressure of about 0.9 psi (6.2 kPa). This assembly is placed in a 140F (60C), or other agreed upon temperature, oven for 1 h. When cooled, the resulting paint surfaces are rated on the numerical scale of 0 to 10, which corresponds to a subjective rating of an impression resulting from their being in contact with the cheesecloth.
5. Significance and Use 5.1 The ability of a coating to resist printing is important
because its appearance is adversely affected if the smoothness ofthe coating film is altered by contact with another surface, particularly one with a texture. Interior paint systems, particularly gloss and semigloss on window sills and other

horizontal surfaces, often have objects such as flower pots placed on them that may tend to leave a permanent impression. This tendency for a paint film to "print" is a function of the hardness of the coating, the pressure, temperature, humidity, and the duration of time that the object is in contact with the painted surface.
6. Apparatus
6.1 Conditioning Room, at 65 to 85F (18 to 29.5'C) and 40 to 60 % relative humidity.
6.2 Glass Slides, approximately 3 by 6 in. (75 by 150 mm).
6.3 Drawdown Applicator, 3-in. (75-mm) wide with a clearance of 6 mils (150 pm).
6.4 Oven, maintained at 140 + 3.5F (60 2C) or, other agreed upon temperature.
6.5 Rubber Stoppers, No. 8 (40-mm top diameter and 32-mm bottom diameter).
6.6 Cheesecloth, medium weave.4 6.7 Scissors. 6.8 Weight, 500-g.
7. Procedure
7.1 Cast the paints being tested on glass slides using a drawdown applicator with a clearance of 6 mils (150 pm), Allow the coated glass slides to dry in the conditioned room for 7 days.
7.2 Cut out approximately 1 lh by 1 Vh-in. (40 by 40-mm) pieces of cheesecloth, one piece for each slide. Use cheese cloth that is usually supplied with 4 intact layers. Do not separate the layers.
7.3 Place the test slides on a horizontal tray, painted face upward, then place one piece of cheesecloth over each slide and top with the small diameter face of a No. 8 stopper and a 500-g weight, one weight and stopper for each specimen. (Weights and stoppers should be equilibrated in the oven prior to running the test) It is recommended that control paints of known satisfactory and unsatisfactory performance be used in each test run and that the tests be run in duplicate.
7.4 Place the entire assembly in the oven and remove it after exactly 1 h. Immediately lift off the weights and stoppers without disturbing the cheesecloth and allow to cool.
7.5 After approximately Vi h, remove the cheesecloths and carefully examine the appearance of the films under neath. Note the depth and amount of cheesecloth pattern left in the paint film. If necessary examine the panel, for better

8. Interpretation of Results
8.1 Rate print resistance is rated on a numerical scale of 0 to 10 corresponding to a subjective rating of the degree to which the paint film has been imprinted. Record the numerical value for print resistance in accordance with the following ASTM style rating or scoring system:
Numerical Rating
10 8 6 4 2 0
Qualitative Characterization (Resistance to Printing)
perfect very good good fair poor very poor
Quantitative Desert (Amount of Print
none very slight slight moderate considerable very great
9. Report
9.1 Report the print resistance rating determined accordance with 8.1. Specify temperature used.
10. Precision
10.1 Data are unavailable for a conventional intra- and interlaboratory precision statement. However, based on actual laboratory experience, with experienced operators, the repeatability is estimated to be plus or minus one unit. The employment of common control paints with mutually agreed ratings should make it possible for interlaboratory agreement (reproducibility) to approach intralaboratory agreement (repeatability). Although numerical ratings may differ with different operators or at different times, ranking should be about the same. As in many tests the precision improves with practice.

Standard Test Methods for Relative Tinting Strength of Printing Ink Dispersions1
This standard is issued under the fixed designation D 2066; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year oflast reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
\. Scope
1.1 These test methods cover procedures for determining the relative tinting strength of printing ink dispersions by yisual or instrumental evaluation.
1.2 These test methods are applicable to paste-type printing inks, flushed pigments, and other pigment disper sions that are essentially nonvolatile under ordinary room conditions and for which there is a wet reference standard of the same pigmentation and consistency. With proper choice of tinting base, they are applicable to dispersions of any color, including black and white.
N' 1--The instrumental procedures for tinting strength are sim
ilar in principle to those described in Test Methods D 387, D 2745, and D4838.2''
1.3 This standard does not purport to address the safety problems, if any, associated with its use. It is the responsi bility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Definitions relating to color attributes and color differences are covered in Terminology D 16 and E 284.
3.2 Descriptions ofTerms Specific to This Standard: 3.2.1 tinting strength--the ability of a material to impart its color to a standard base; the reciprocal of the relative concentration required to match the reference material in a standard base. 3.2.2 masstone (or masscolor)--the color of a material that is thick enough to mask any background. 3.2.3 undertone (or undercolor)--the color of a thin film of a material.
4. Summary of Test Methods
4.1 Thin and thick films of the standard and unknown dispersions are drawn down in juxtaposition on bond and on coated paper, Visual evaluation ofthe relative undertone and masstone provides a check on color equivalency.
4.2 The standard and unknown dispersions are each reduced to the same concentration in a suitable tinting base. Thick wet drawdowns of the two tints are evaluated for tinting strength by Test Methods A or B.
4.2.1 Test Method A--Visual Evaluation: If the strength of the tints isjudged unequal, aliquots of the stronger tint are further reduced until equivalence is obtained. The tinting strength of the unknown dispersion is calculated from the weight of extra tinting base added per unit weight of the stronger tint.
4.2.2 Test Method B--Instrumented Evaluation: Reflec tance measurements are made on thick wet films of the original tints. The tinting strength ofthe unknown dispersion is calculated according to the Kubelka-Munk equation.
4.3 Preparation of a confirming tint is recommended as an unbiased method of verification. The preferred approach is to prepare a new tint of the unknown at a concentration calculated to match the standard tint.

10. Preparation of Tints
10.1 Select a tinting base appropriate to the sample being tested (see 7.2). Examine the base for uniformity. If there are signs of separation or settling, stir thoroughly in container. If necessary, transfer the quantity required for testing to a slab and mix to ensure that the same composition of base will be used for both the standard and the unknown samples.
10.2 Tare or counterbalance a weighing substrate. Using guidelines suggested in Table 1, weigh out the desired amount ofthe standard dispersion. The quantity of specimen need not be exactly as listed in Table 1 but must be weighed to at least three significant figures. Divide the actual weight by the desired decimal concentration to obtain the total tint weight. The difference between the total weight and the specimen weight represents the weight of bleaching base to
be added. 10.3 Gently mix the specimen and tinting base on the
weighing substrate until the tint is uniform. Use a circular stirring motion, periodically scraping all material from the surface of the substrate. Do not use so much energy that further dispersion will result. If necessary, transfer all mate-

rial to a glass slab and continue mixing with a gentle scraping and stirring motion until a uniform color with no specks or streaks is achieved. With a clean putty knife, push the tint to one side of the slab. Clean the putty knife and remainder of the slab.
N' 6--With flushes and other high viscosity dispersions, it is
recommended that the tinting base be mixed into the specimen in small increments.
10.4 Repeat 10.2 and 10.3 with the unknown dispersion. Be sure the specimen concentration in the tint and the type of tinting base are identical to that used for the standard dispersion.
10.5 If there will be a delay in the evaluation process, transfer the tints to small clean containers and label appro priately. Always gently restir immediately before subsequent use in order to minimize problems of flooding or floating.
TEST METHOD A--TINTING STRENGTH BY VISUAL EVALUATION
11. Procedure
11.1 Using separate ink knives, gently stir the standard and the test tints. Place a small quantity of each tint close together, but not touching, at one end of a small glass plate or other drawdown substrate. Hold the drawdown knife at a low angle (5 to 15from horizontal) and, using light pressure, draw down the tints in juxtaposition. The two films must be in contact with each other, smooth, and sufficiently thick so as to mask any background.
11.2 Immediately examine the drawdowns under the standard light If the two tints appear equal, record the tinting strength of the unknown as 100 %. If the tints are unequal in strength, estimate the strength difference between the stronger and weaker color either from experience or from instrumental measurements (see Eq 4a or 4b in 13.2.2).
N' 7--With colored and black samples, the stronger tint will be
darker. With white samples, the stronger tint will be lighter.
11.3 Weigh to three significant figures an aliquot of about 1 g (or a quantity representing about 10 to 20 %) of the stronger tint Multiply the exact weight by the estimated strength difference in decimal units; add tinting base accord ingly. For example, for an estimated 10 % difference, add 0.10 g base/g aliquot of the stronger tint.
11.4 Gently mix the adjusted tint until uniform. Gently remix the original tint of the weaker dispersion, make a thick drawdown versus the adjusted tint as in 11.1, and examine as in 11.2..
11.5 If the drawdowns are still unequal, discard the adjusted tint. Weigh out a new aliquot of the stronger tint and add more or less tinting base than in 11.3.
11.6 Repeat 11.3 and 11.4 until the drawdowns show that the adjusted tint equals the strength of the lighter tint. When equivalency is obtained, record whether the standard or unknown tint was stronger, the weight of the final aliquot, and the weight of added tinting base.
N' 8--Ifthere is a difference in color between the unknown and
standard dispersions, a situation will result wherein, as dilution progresses, feedarker- tint wiferevert to fee lighter tint without obtaining a match. In such cases, this method cannot be used (see Note 5).
11.7 Compute the strength of the unknown dispersion (u)
245
DUP050297428
D2066
as a percentage of a standard dispersion(s) as follows:
1 + {bfa)u
TSW %
x 100
1 + (.b/a).
(1)
where: TSU = tinting strength of the unknown dispersion, b = weight of extra tinting base added to an aliquot of
the stronger tint to obtain equivalence, g, and
a = weight of the aliquot, g. The term b/a represents the strength difference between the stronger and weaker colorant. For the weaker dispersion, b/a = 0 and drops out of Eq 1. When the unknown dispersion is
stronger, Eq 1 reduces to:
TSU, % = 1 + (b/a)u x 100
(la)
When the standard dispersion is stronger, Eq 1 reduces to:
TSU, % =------------ x 100 1 + (b/a).
(lb)
N' 9--Tinting strength is always expressed as a decimal or a
percentage of the unknown relative to the standard. The practice of
expressing results as a strength difference may lead to erroneous
calculations of the replacement concentration. See Eq 3 in 13.1.
11.8 Since replication of visual tinting strength tests inherently suffers from bias, prepare a confirming tint in accordance with the procedure given in 13.1.
TEST METHOD B--TINTING STRENGTH BY INSTRUMENTAL EVALUATION
12. Procedure
12.1 Set the instrument for the large area of view or illumination and standardize in accordance with Test Methods E 1331, E 1347, or E 1349, or, in the case of a densitometer, the manufacturer's instructions. If it is the intent to make measurements directly on wet tints, it may be useful to protect the instrument with a material such as plastic wrap with the porthole cut out.
12.2 Gently remix the standard tint prepared in Section
10. Place a sufficient quantity on a small glass plate or other rigid surface so that the material is at least 30 to 35 mm in diameter and thick enough to mask any background. Alter natively, use a standard spacer (see 7.6) to prepare a thick sandwich between two microscope cover glasses.
12.3 Measure the reflectance factor in one ofthe following manners:
12.3.1 Spectrophotometer: Following the procedure given in Test Method E 1331 or E 1349, quickly mountthe tint on the porthole of the spectrophotometer and, within or at 45 s, measure the reflectance factor between 420 and 680 nm. If hemispherical geometry is used, the specular component may be either included or excluded, as long as the same condition is consistently used. Make a minimum of two measurements, moving or rotating the specimen between runs. Record the spectral reflectance factor in decimal units at the wavelength ofmaximum absorption (minimum reflec tance) and compute the mean.
12.3.2 Densitometer: If the tint involves black, white or a process color, select the filter having the appropriate Status T or Status E response in accordance with ANSI Standard PH 2.18. The peak transmission of The visual response filter should be at 555 nm for blacks and whites; of the blue filter, at 460 nm (Status T) or 440 nm (Status E) for process
yellows; of the green filter, at 530 nm for magentas; of the red filter, at 600 nm for cyans. Make measurements as in 12.3.1 at two or three different locations. If the readout is density, convert to the reflectance factor as follows:
R = 10--.
s
;
i
If the readout is percent reflectance, record in decimal units, 12.4 Alternatively, measure the CIE tristimulus values of
the specimen on a spectrophotometer in accordance with Test Method E 1331 or Test Method E 1349 or on a tristimulus colorimeter in accordance with Test Method E 1347. Make the measurements as in 12.3.1. If hemispher ical geometry is used, the specular component may be either included or excluded as long as the same condition is consistently used. The tristimulus values may be based on either the CIE 1964 (10`) supplementary standard observer and standard illuminant D65 or the CIE 1931 (2) standard observer and standard illuminant C, as long as the same basis is consistently used. Record in decimal units the lowest appropriate value, for example, X with blue colon, Y with -reds, blacks, and whites, or Z with yellows.
12.5 Repeat 12.2 and 12.3 or 12.4 with the unknown tint. 12.6 Calculate the tinting strength of the unknown disper sion according to the Kubelka-Munk equation as follows:
:
[(1 TSU, x 100
[(I - RJ2/2RJs
(2)
where:
= spectral reflectance factor, expressed as a decimal fraction, of an infinitely thick layer of material (at the wavelength of maximum absorption), or, by mutual agreement, an appropriate tristimulus value.
N' 10--If the tint represents a white pigment, use Eq 2 in the
inverted form.
N' 11--The term ((1 - J?J2/2RJ represents KjS of the colorant,
where K is the absorption coefficient and S is the scattering coefficient, both of which are specific to a colorant. Therefore, if the pigmentation
in the unknown dispersion is different from that in the standard dispersion, that is, the dispersions are metameric, Eq 2 no longer applies, The equation is also reported to work best when the reflectance factor or tristimulus value of the tints used is about 0.40 and the tinting strength ofthe unknown is within 10 % of the standard.
l !
\ f
12.7 If the tinting strength result for the unknown is not within 10 % of the standard, reduce an aliquot of the stronger tint by the procedure given in 13.2. Remeasure the adjusted tint and calculate a new tinting strength value (see 13.2.5).
12.8 Prepare a confirming tint (see 13.1) if the original tinting strength value was not within 10 % of the standard (see 13.1 or 13.2 ifwithin 10 %).

similar to that employed in 10.2. Divide the actual weight by q to obtain the total tint weight. The difference between the total and the specimen weight represents the weight oftinting base to be added. Mix as in 10.3.
13.1.4 Gently remix the original tint of the standard
dispersion- Make a thick drawdown of both tints as in 11.1. If the two tints match, the tinting strength result computed for the unknown dispersion is correct.
13.1.5 Failure of the two tints to match suggests a
weighing error or inadequate mixing of .the tints. Clean up and start over from Section 10.
13.1.6 Use Eq 3 to compute the color/money/value of a colorant from different sources or grades (optional). Multiply C and Cs by their respective unit costs. Add to each the costs of other components in a formulation, represented by (1 -- Ca) and (1 - Cs). The lower total cost figure is the better
value. 13.2 Reduction of the Stronger Tint: 13.2.1 In this method of confirmation, the instrumental
tinting strength result is used to calculate the strength difference between the stronger and weaker dispersion. An aliquot of the stronger tint is reduced accordingly.
13.2.2 Compute the strength difference, bja by re-ar rangement of Eq la or lb. If the test dispersion is the stronger, that is, TSU in decimal units is greater than 1.0
then:
(h/a)u = TSU - 1
(4a)
If the standard dispersion is the stronger, that is, TSU is less than 1.0 then:
(A/)s = (i/ra,,)-1
(4b>
13.2.3 Weigh out an aliquot of the stronger tint as in 11.3. Multiply the exact weight by bja to obtain the weight of bleaching base to be added. Mix the adjusted tint until uniform.
13.2.4 Evaluate the adjusted tint by either ofthe following
procedures: 13.2.4.1 Visual Evaluation-Draw down the adjusted tint
versus the original tint of the weaker color as in 11.1.4.
Failure to obtain equivalency on the first cut may suggest a weighing error or the inapplicability of the Kubelka-Munk equation (Eq 2), or both. If necessary, reduce a new aliquot
until equivalency is obtained. Calculate the correct tinting strength according to Eq la or lb.
13.2.4.2 Instrumental Evaluation--Prepare a thick film of
foe adjusted tint, remeasure the reflectance, and calculate the adjusted tinting strength by Eq 2. If 100%, the original tinting strength value is correct. If not 100 %, compute the correct tinting strength by multiplying the original tinting strength percentage by the adjusted tinting strength in decimal units.
14.1.1 The type and identification of the test dispersion, the reference standard dispeision, and the nature of the tinting base,
14.1.2 The results of the visual evaluation of the relative color difference (masstone and undertone) of the drawdowns on bond and coated paper,
14.1.3 The relative tinting strength and the method by which it was determined (visual or instrumental). If the instrumental method was used, the manufacturer and type of instrument, the geometry (including for hemispherical geom etry whether the specular component was included or excluded) and, if used, the basis for the calculation of tristimulus values,
14.1.4 The method, if any, by which the tinting strength result was confirmed, and
14.1.5 Any deviation, by agreement or otherwise, from the procedures given in these test methods.
15* Precision and Bias
15.1 Precision: 15.1.1 An interlaboratory study of these test methods was conducted in which 3 sets of process color printing inks ranging in tinting strength from 75 to 85 % were tested by operators in 6 different laboratories. The tests were con ducted as blind duplicates on each of 2 days. In addition to visually evaluated tinting strength, the same reductions were measured spectrophotometricaliy or densitometrically, or both. The estimated standard deviations and the degrees of freedom are given in Table 2. Based on these standard deviations, the following criteria should be used for judging the acceptability of results at the 95 % confidence level: 15.1.1.1 Repeatability--Two results obtained by the same operator on different days should be considered suspect if they differ by more than the maximum allowable difference indicated in Table 2. 15.1.1.2 Reproducibility--Two results, each the mean of results obtained on different days by operators in different laboratories, should be considered suspect if they differ by more than the maximum allowable difference indicated in Table 2. 15.2 Bias--The tinting strength results obtained in the interlaboratory study of these test methods were higher than the formulated values by the amounts shown in Table 3.

3.1 This practice describes methods of preparation that provide galvanized surfaces suitable for painting, specifically so that an applied coating system can develop the adhesion necessary for satisfactory service life.
3.2 Six methods of surface preparation (Note 1) are covered as follows:
3.2.1 Method A--Crystalline Zinc Phosphate Treatment.
1 This practice is under the jurisdiction of ASTM Committee D-1 on Paint and
Related Coatings and Materials and is the direct responsibility of Subcommittee D01.46 on Industrial Protective Coatings.

3.2.6 Method F--Amorphous Complex-Oxide Treat ment.
N' 1--Materials employed in these methods of treatment are
available from a number of sources as proprietary compounds or
methods. Selection may be made from available sources.
3.3 Variations in surface preparation produce end condi
tions that differ and that do not necessarily yield identical results when paints are applied. Service conditions will dictate the type of surface preparation to be selected, although the quality produced by any individual method may vary with different zinc coatings.

3.5 This practice does not describe the cleaning necessary to provide a zinc-coated (galvanized) surface suitable for the
application of the treatments. Many cleaning methods are
applicable and should be agreed upon between the purchaser and the supplier.
N ' 2--Most producers ofzinc-coated (galvanized) steel sheets and coils have adopted the practice of applying an inhibitor to the zinc surface to give temporary protection against staining by moisture during
shipping or storage. Some of these inhibitors will interfere with proper reaction of most of the treatments described in these methods, and an
unsatisfactory surface for painting will result. It is strongly recom mended that the purchaser consult the supplier of the chemical
treatment to be used as to the suitability of the zinc surfaces for treatment by any of these methods (see Appendix X2).
4. Significance and Use
4.1 This practice describes procedures that can be used to prepare new zinc-coated surfaces for painting and improve the bond of paint to the zinc surface.
5. Processes
5.1 Method A, Crystalline Zinc Phosphate Treatment-- This conversion-coating method consists of reacting the zinc surface in a zinc acid phosphate solution containing oxi-
251
DUP05 02 97434
# D 2092
living agents and other salts for accelerating the coating
action. The zinc surface is converted to a crystalline phos phate coating of the proper texture to inhibit corrosion and increase the adherence and durability of the paint film. Such treatments are recommended for product finishes and may be carried out by immersion, spray, or brush application.
5.2 Method B, Chromate Treatment--This treatment consists of a dip or spray with a dilute solution of a mixture of chromium trioxide and other acids, with the proper accelerator, for a period from 5 to 30 s at room temperature to 130F (55C) to provide a thin amorphous chromate coating that increases corrosion resistance and paint adhe
sion. 5.3 Method C, Aqueous Chromic-Organic Treatments--
Certain water-soluble resins, when properly formulated with chromium compounds, may be applied to zinc surfaces by roller coat or other suitable means, such as dip and squeegee rolls. This may be done over a wide temperature range provided the film is properly baked or cured, or both, as required by the paint system to be applied. The resultant coating provides a corrosion-resistant film that increases the adhesion of applied paint films.
5.4 Method D, Acid-Bound Resinous Treatment (Vinyl Wash Primer) (See DoD-P-15328 and SSPC-Paint No. 27)--This surface treatment is based on the application ofan acid-bound resinous film of approximately 0,3 to 0.5 mil (8 to 13 pm) thickness. The treatment is based on three primary components: a hydroxyl-containing resin, a pigment capable of reacting with die resin and an acid, and an acid capable of
insolubilizing the resin by reacting with the resin, the pigment, and the zinc surface. The film is usually applied by spray, but may be applied by brash, dip, or roller coater.
Under normal conditions it will dry sufficiently for recoating within 30 min, and within 8 h it will not be softened by organic solvents commonly used in paint coatings. The film has good adhesion to the metal substrate and promotes good adhesion of most subsequent organic coatings to itself. Two types of this treatment are available: (2) two-package mate rial to be used the day it is mixed and (2) one-package material that has package stability and does not require daily preparation.
N' 3--It may be difficult to control the dry film thickness within
the parameters of this specification when applied by brush, roller, or dip coater.
5.5 Method E, Annealing Heat Treatments--Under the controlled conditions obtainable in a mill, hot-dip galvanized surfaces may be converted and alloyed with the base metal to change the surface character of the zinc coating and make it more` receptive to paint. This surface can be further im' proved by treating in accordance with Methods A, B, C, or D.
5.6 Method F, Amorphous Complex-Oxide Treatment-- This surface treatment method consists of reacting the zinc surface in an alkaline solution containing heavy metal ions for a period of 5 to 30 s at 115 to 160F (45 to 70C). The surface ofthe zinc is converted to a nonmetallic, amorphous, complex-oxide coating that inhibits corrosion and increases the adhesion and durability of paint finishes. The treatment can be carried out by immersion or spray application.

XI. CLEANING OF ZINC SURFACES
X1.1 When zinc surfaces treated by Methods A through F have been soiled in fabrication, they should be cleaned before finishing. Alkali and acid cleaners should not be used without consulting the supplier of the treatment Organic solvents will remove most soils but will not remove watersoluble salts unless specially selected. Proprietary solutions designed to clean zinc surfaces are available.
XI.2 New zinc-coated steel surfaces that cannot be treated in accordance with these methods prior to painting
can be exposed to the weather for at least 6 months prior to painting to allow the surface to oxidize.5
N' XI.I--There are special primers that obviate the need for
weathering--U.S. Fed. Spec. TT-P-641 and CGSB, l-GP-198 are examples.
5Literature on painting zinc-coated steel surfaces may be obtained from the American Zinc Institute, 292 Madison Ave., New York, NY 10017, or from th: National Paint, Varnish, and Lacquer Assoc., 15 Rhode Island Ave., N.W., Washington, DC 20005.

X2. IDENTIFYING THE PRESENCE OF AND REMOVING CHROMATE TREATMENTS USED AS WET-STORAGE (ALSO CALLED HUMID-STORAGE) STAIN INHIBITORS
X2.1 One of the inhibitors used by producers of zinccoated steel is a hexavalent chromium solution. This treat
ment prevents Method D from working properly. X2.2 If zinc-coated steel to be painted is galvanized to
order, the order should prohibit the use of hexavalent chromium humid-storage stain treatments.
X2.3 Hexavalent chromium treatment can be removed
from galvanized surfaces by one of the following three methods:
X2.3.1 Weathering the surfaces for six months. X2.3.2 Abrading the surfaces by sanding. X2.3.3 Brush-off abrasive blast cleaning. X2.4 The presence of hexavalent chromium on gabsnized surfaces can be determined by spot testing with

used to evaluate the effectiveness of preparation to remove the treatment.
X2.5 Make the spot test solution as follows: X2.5.1 Dissolve 0.5 g of 1,5-diphenylcarbohydrazide powder in a mixture of 20 mL acetone and 20 mL denatured ethanol. Heat the mixture in a warm water bath if necessary. X2.5.2 Dilute 20 mL of concentrated phosphoric acid to 40 mL by slowly adding to 20 mL of distilled or deionized water. X2.5.3 Add the dilute phosphoric acid to the acetonealcohol solution. X2.5.4 Store the solution away from light. Discard if it
becomes discolored. Preferably make fresh solution as
needed using proportionally smaller amounts of ingredients. X2.6 Conduct the spot test as follows:
X2.6.1 Degrease the test spot on the galvanized surface. X2.6.2 Place several drops of the test solution on the galvanized surface.
X2.6.3 If no color develops in the solution within 10 s, hexavalent chromium is not present.
X2.6.4 If solution droplets turn a pink to purple color, then hexavalent chromium is present.
X2.6.5 Conduct the spot test on several representative spots on each individual piece of galvanized steel.
X2.6.6 Test every piece of galvanized steel that is to be treated for painting.

3. Summary of Test Methods
3.1 Test Method A consists of determining the apparent viscosity of coatings and related materials by measuring the torque on a spindle rotating at a constant speed in the material.
3.2 Test Methods B and C consist of determining the shear thinning and thixotropic (time-dependent) rheological properties of the materials.3 The viscosities of these materials are determined at a series of prescribed speeds of a rota tional-type viscometer. The agitation of the material imme diately preceding the viscosity measurements is carefully controlled.
4. Significance and Use
4.1 Test Method A is used for determining the apparent viscosity at a given rotational speed, although viscosities at two or more speeds better characterize a non-Newtonian material than does tke single viscosity measurement.
4.2 With Test Methods B and C, the extent of shear

thinning is indicated by the drop in viscosity with increasing viscometer speed. The degree of thixotropy is indicated by comparison of viscosities at increasing and decreasing vis cometer speeds (Test Method B), viscosity recovery (Test Method B), or viscosities before and after high shear (combi nation of Test Methods B and C). The high-shear treatment in Test Method C approximates shearing during paint appli cation. The viscosity behavior measured after high shear is indicative of the characteristics of the paint soon after application.

agreed-upon temperature) for 1 h in a l-pf(0.5-L) can, 33/s in. (85 mm) in diameter. Measure the viscosities of each oil as described in Test Method B (Section 13) taking readings only at increasing speeds (13.7). Make certain that the spindle is centered in the container prior to taking measure
ments.
N' 1--The Brookfield LV and RV series viscometers are equipped
with a spindle guard leg. The spindle/speed multiplying factors (Table 1)
are designed for use with the guard leg in place except for the following conditions: RV series when the factors are the same with or without the guard leg for spindles No. 3 through 7; or LV series when the factors are
the same with or without the guard leg for spindles No. 3 and 4.
7.1.1 Calibration in a 1-pt (0.5-L) can is always possible with the LV series viscometer with the guard leg attached. Calibration of the RV series viscometer in the 1-pt can must be done with spindles No. 3 through 7 without the guard leg. If the No. 1 or No. 2 spindles are to be used, calibration is carried out in the 1-qt (1-L) can with the guard leg attached.
7.2 Combining the tolerance of the viscometer (1 %, equal to the spindle/speed factor) and the tolerance of the temperature control (typically 0.5C at 25I>C) it is reason able to assume that a viscometer is calibrated if the calcu lated viscosities are within 5 % of the stated values (see Table 2 for examples of the considerable change in viscosity with temperature exhibited by standard oils). If measure ments are not made at 25C, then the stated viscosities should be corrected to the temperature at which they are measured. If the viscosities determined in 7.1 differ from the stated values of the viscosity standard by more than 5 %, calculate new factors for each spindle/speed combination as
follows:
/= V/s
(1)
where: f = new factor for converting scale reading to viscosity, cP
(mPa-s), V = viscosity of standard oil, mPa-s, and
s = scale reading of the viscometer.

8. Preparation of Specimen
8.1 Fill a 1-pt or 1-qt can with sample to within 1 in. (25 mm) of the top with the sample and bring it as close as possible to a temperature of 25C or other agreed-upon temperature prior to test.
8.2 Vigorously shake the specimen on the shaker or equivalent for 10 min, remove it from the shaker, and allow it to stand undisturbed for 60 min at 25C prior to testing (Note 2). Start the test no later than 65 min after removing the can from the shaker. Do not transfer the specimen from the container in which it was shaken.
N' 2--Shake time may be reduced if necessary, or as agreed upon
between the purchaser and manufacturer, but, in any case, should not be less than 3 min.

TEST METHOD A--APPARENT VISCOSITY
9. Procedure
9.1 Make all measurements as close as possible to 25C, or
other agreed-upon temperature.
9.2 Place the instrument on the adjustable stand. Lower j
the viscometer to a level that will immerse the spindle to the
proper depth. Level the instrument using the attached spirit I
level.
9.3 Tilt the selected spindle (Note 3), insert it into one 1
side of the center of the surface of the material, and attach
the spindle to the instrument as follows: Firmly hold the |
upper shaft coupling with thumb and forefinger; screw
left-hand thread spindle coupling securely to the upper shaft
coupling being very careful when connecting to avoid undue |
side pressure which might affect alignment. Avoid rotating
the dial so that pointer touches the stops at either extreme of
the scale.
j
N' 3--Select the spindle/speed combination that will give a
minimum scaie reading of 10 but preferably in the middle or upper
portion of the scale. The speed and spindle to be used may differ from this by agreement between user and producer.
9.4 Lower the viscometer until the groove (immersion mark) on the shaft just touches the material. Adjust the viscometer level if necessary. Move the container slowly in a
horizontal plane until the spindle is located in approximately the center of the container so that the test will be run in a, region undisturbed by the lowering of the spindle. .
9.5 Turn on the viscometer. Adjust the viscometer to th^ j rpm. selected (Note 3) for the material under test. Allow the viscometer to run until the pointer has stabilized (Note 4). After the pointer has stabilized, depress the clutch and switch

jO. Calculation
10.1 Calculate the apparent viscosity at each speed, as follows:
V = fs
where: y s viscosity of sample in centipoises, mPa-s, r = scale factor furnished with instrument (see Table 1),
and s = scale reading of viscometer.

CONDITIONS, DEGREE OF SHEAR THINNING AND THIXOTROPY
13. Procedure
13.1 Make all measurements with the Brookfield viscometer as close as possible to 2SC, or other agreed upon temperature.
13.2 Adjust the instrument and attach the spindle as in 9.2 through 9.4.
13.3 Set the viscometer at the slowest rotational speed (Notes 5 and 6). Start the viscometer and record the scale reading after ten revolutions (or other agreed-upon number of revolutions).
N"#' 6--When the eight speed viscometers (RVT and LVT) are
used, lower or higher speeds than that permitted by the four speed viscometers may be used upon agreement between producer and user.
13.4 Increase the viscometer speed stepwise and record the scale reading after ten revolutions (or equivalent time for each spindle/speed combination) at each speed After an ob servation has been made at the top speed, decrease the speed in steps to the slowest speed, recording the scale reading after ten revolutions (or equivalent time) at each speed.
N$%' 7--It is preferable to change speed when the motor is running.
13.5 After the last reading has been taken at the slowest speed, shut off the viscometer and allow it and the specimen to stand undisturbed for an agreed-upon rest period. At the
end of the rest period, start the viscometer at the slowest speed and record the scale reading after ten revolutions (or other agreed-upon number of revolutions).
14. Calculations and Interpretation of Results
14.1 Calculate the apparent viscosity at each speed as shown in Section 9.
14.2 If desired, determine the degree of shear thinning by the following method:
14.2.1 Shear Thinning Index (sometimes erroneously called the thixotropic index)--Divide the apparent viscosity at a low rotational speed by the viscosity at a speed ten times higher. Typical speed combinations are 2 and 20 rpm, 5 and 50 rpm, 6 and 60 rpm but selection is subject to agreement between producer and user. The resultant viscosity ratio is an index of the degree of shear thinning over that range of rotational speed with higher ratios indicating greater shear thinning.
14.2.2 A regular or log-log plot of viscosity versus viscometer speed in rpm may also be useful in characterizing the shear-thinning behavior of the material. Such plots may be used for making comparisons between paints or other materials.
14.3 If desired, estimate the degree of thixotropy (under conditions of limited shearing-out of structure) by one of the following methods:
14.3.1 Calculate the ratio of the slowest speed viscosity taken with increasing speed to that with decreasing speed. The higher the ratio, the greater the thixotropy.
14.3.2 Calculate the ratio of the slowest speed viscosity taken after the rest period to that before the rest period. The higher the ratio, the greater the thixotropy.
15. Report
15.1 Report the following information: 15.1.1 The Brookfield viscometer and spindle, 15.1.2 The viscosities at increasing and decreasing spindle speeds, 15.1.3 The rest period time and the viscosity at the end of that time, 15.1.4 The specimen temperature in degrees Celsius, and 15.1.5 The shake time if other than that specified. 15.2 Optional Reporting: 15.2.1 Degree of Shear Thinning--Shear thinning index and speeds over which it was measured (14.2). 15.2.2 Estimated Degree, of Thixotropy (under conditions of shearing-out of structure)--Ratio of the lowest speed viscosities, for both increasing and decreasing speeds; or ratio ofthe lowest speed viscosities before and after the rest period, and speed at which they were measured (14.3).
16. Precision and Bias
16.1 Precision--See Section 23 for precision, including that for measurement of the shear thinning index (ratio of viscosity at 5 r/min to that at 50 r/min). It has not been possible to devise a method for determining precision for viscosities at increasing and decreasing speeds other than as individual measurements. No attempt was made to deter mine the precision of the measurement of the degree of thixotropy because this parameter is dependent on the material, the time of the test, and other variables.

20. Calculations and Interpretation of Results
20.1 As in Test Method B, calculate the viscosities at each decreasing speed.
20.2 If desired, calculate the degree of shear thinning by the method given in Test Method B, 14.2. The measured viscosity behavior after shearing is essentially that of the paint immediately after application (disregarding changes in solids).
20.3 If desipd, estimate the degree of thixotropy (under conditions of complete shearing-out of structure) by calcu lating the ratio of the lowest speed viscosities before and after shear. The lowest speed before-shear viscosity is taken from Test Method B, 14.1, at the lowest increasing speed. The lowest speed after-shear viscosity is taken from 20.1. The higher the ratio, the greater the thixotropy.
cient of variation for Test Method A (angle speed) was found to be 2.49 % with 121 degrees of freedom and for Test Method B (Shear Thinning Index) 3.3 % with ,31 degrees of freedom. The corresponding between-Iabpratories coeffi cients are 7.68 % with 105 degrees of freedom and 7.63 % with 27 degrees of freedom. Based on these coefficients the following criteria should be used forjudging the acceptability of results at thei95 % confidence level:
23.1.1 Repeatability--Two results obtained by the same operator at different times should be considered suspect if they differ by more than 7 % relative. for single speed viscosity and 9.5 % relative for shear thinning index.
23.1.2 Reproducibility--Two results obtained by opera tors in different laboratories should be considered suspect if they differ by more than 21.6 and 22.1 % relative, respec tively, for the same two test methods.

FIG. 1 Balanced-Beam Scrape-Adhesion Tester
8. Procedure
8.1 When using the instrument shown in Fig. 1, level the base plate of the apparatus and place it so that the weight holder is toward the operator. This places the beam release on the operator's right and allows freedom to move the test specimen manually under the weighted scraping element (loop). Adjust the main bearing support so that the beam is _ balanced in the horizontal plane when the loop is just"'
touching the specimen surface. 8.2 Raise the beam and lock it. Wipe the loop with clean
cloth or chamois. Place a test panel on the sliding platform so that it may be moved away from the operator and the uncoated portion is toward the main beam support. Place weights on the weight support using an initial amount that is estimated to be appropriate for the particular coating. Carefully lower the beam until the loop rests on the uncoated portion ofthe test specimen and the hill load is applied, then slowly (1 to 2 s/in.) push the sliding platform away from the operator for a distance of at least 3 in. (75 mm). If the coating is removed, continue the testing, using successively smaller loads (0.5-kg increments) until the coating is not removed. If the coating is not removed by the initial scrape, continue the testing, using successively larger loads (0.5-kg increments) until the coating is removed or until the maximum load of 10 kg has been applied. Use a new area of
the test surface each time a scrape is made. 8.3 When the critical load has been approximately lo
cated, repeat the test five times at each of three loadings: above, below, and at the load determined in the first trial. Apply the different loads in random fashion so that all scrapes at one load are not made in succession or on one panel.
8.3.1 Periodically examine the loop to ensure that the
original smooth surface is intact. If the contacting surface is worn, reverse the loop. When both sides are worn, replace with a new loop.
8.4 For each applied load, tabulate the number of times the coating was removed or adhered. The load where the scrape results change from mainly adhering to mainly removed, ignoring the first Vi in. (13 mm) of the scratch if the coating was removed, is the adhesion failure end point.
9. Report
9.1 Report the following information: 9.1.1 Load in kilograms at the adhesion failure end point 9.1.2 Panel material and surface preparation. 9.1.3 Dry-film thickness. 9.1.4 Any deviation from the specified procedure.
[; [ | ;
10. Precision
10.1 Correlation--This method was developed when cor relation with other methods of assessing adhesion was considered to be of equal importance to the agreement between results obtained in the same or different laboratories. It was established that when materials differing widely in hardness and adhesion were evaluated by a number of experienced personnel in several laboratories, the adhesion results obtained using this method correlated well with those obtained with several other methods.
10.2 Precision--If sufficient cooperators can be obtained, an interlaboratory study will be conducted to establish precision.

Standard Method for Measurement of Plasticizer Migration From Vinyl Fabrics to Lacquers1
This standard is issued under the fixed designation D 2199; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
j. Scope 1.1 This method covers an accelerated test for the mea
surement of a tendency for plasticizers in finished vinyl fabric to be transferred to coatings with which they come in contact.
NOTE--Age offabric sample may affect results oftest. To ensure most pliable results, test with fabric sample closest in age to what will be toated.
1.2 This standard may involve hazardous materials, oper ations, and eqidpment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.
2. Summary of Method
2.1 A small sample of vinyl fabric is placed on a condi tioned coating film under a pressure of Vz psi (3.45 kPa). The assembly is placed in an oven for 3 days at elevated temperature. At the end ofthat time, the coating is examined for marring or softening. For coatings that may block or print at 50C or lower, a lower test temperature and a longer test time may have to be used.
3. Significance and Use
3.1 Plasticizers in finished vinyl fabric can be transferred to coatings with which they come in contact. When this takes place, objectionable marring and softening occur. This method covers an accelerated test for measurement of this tendency.
4. Apparatus 4.1 Drawdown Blade, 5-mils (125-pm) clearance to pro
vide a wet film of approximately 2.5 mils (63 |xm) in thickness.
4.2 Plate Glass Panels. 4.3 Window Glass, 2 by 2-in. (51 by 51-mm) square, double strength. 4.4 Sponge Rubber, 2 by 2-in. (51 by 51-mm) square by `A in. (6.3 mm) thick. 4.5 Weights, flat-bottom, sufficient to place a total weight of 2 lb (910 g) on each test sample.

4.6 Forced-Convection Oven, thermostatically controlled to 2C.
4.7 Photograph Roller? 4.8 Aluminum Foil.
5. Procedure 5.1 Apply the coating to the glass panel with the
drawdown blade to provide a uniform film with an area of at least a 2-in. (51-mm) square and a dry thickness of at least 1 mil (25 pm) or as agreed upon. Dry the coating in accord ance with the recommendations of the manufacturer or for a minimum of 24 h at room temperature and 2 h at 50"C.
5.2 Preheat the glass plate bearing the coating, the 2 by 2-in. glass square, and the weights for 30 min at 50C. Place the square of vinyl fabric on the coating with care and ensure intimate contact by rolling with the photographic roller. Cover the fabric with foil, sponge rubber, glass, and weight in that order. The total weight shall be 2 lb (910 g).
5.3 Place the assembly in the forced convection oven at a temperature of 50C for 72 h. After removal from the oven and cooling, remove the weight, sponge rubber, and alu minum foil, and carefully remove the vinyl fabric. Note and report any resistance to removal. Wipe the surface of the fabric with a soft rag dampened with heptane and examine for removal of exuded plasticizer.
6. Rating 6.1 Rate the degree of migration by viewing the surface of
the coating at a low angle against the light within 2 h after termination of heating and within 15 min of removal of the fabric.
7. Report 7.1 Report marring or softening, or both, on the scale of
no change, faint imprint, severe imprint, or marring. 7.2 If plasticizer is evident when the surface is wiped, this
shall be reported.
8. Precision 8.1 This method does not result in a numerical value for
precision but repeated tests have demonstrated that several laboratories will assign the same rating to various coating fabric combinations. Also, replicate tests by one laboratory are in good agreement.

1. Scope
1.1 The visual surface preparation standards consist of a series of color prints available as separate publications. Two different sets of photographs are described in this standard, designated as Method A (ISO/Swedish Standard2) and Method B (SSPC Standard3). The two methods differ iruthe depiction of the initial surface, in the definition and depic tion of the cleaning conditions, and in the number of cleaning methods included. Because of these differences, the specifier should state whether Method A or Method B should be used.
The colored visual surface preparation standards represent different conditions of hot rolled steel before and after surface preparation. Prior to cleaning, there are four rust grades, A to D, that cover the range from intact mill scale to 100 % rusted and pitted steel. The standards then depict the appearance of the four grades after cleaning by one or more methods (for example, blast cleaning) to various degrees of thoroughness.

3.1 Definitions: 3.1.1 The cleanliness definitions for the Method A visual surface preparation standard appear in the text of the pictorial surface preparation standards publication.2 The definitions for Method B are found in a separate publi cation.3
1 This standard is under the jurisdiction ofASTM Committee D-l on Paint and Related Coatings and Materials and is the direct responsibility of Subcommittee 00] .46 on Industrial Protective Coatings.
The pictorial standards described were prepared by the Swedish Corrosion Inst, and have been jointly approved by ASTM, the Steel Structures Painting Council (Vis 1), and the Swedish Standardizing Commission.

2 The pictorial surface preparation standards are available from ASTM Head quarters (request Adjunct No. 12-422000-00); the Steel Structures Painting Council, 4400 Fifth Ave., Pittsburgh, PA 15213; and Sveriges Standardiseringskommission. Box 3295, Stockholm 3, Sweden.
3 The Visual Standards Method B and surface cleanliness definitions axe available from the Steel Structures Painting Council, 4400 Fifth Avenue, Pittsburgh, PA 15213.
4. Significance and Use
4.1 The appearance of the various degrees of blast cleaning are influenced by the initial rust grades of the steel being cleaned. The standards aid visually in judging and evaluating the degree of rusting before cleaning and the degree of cleaning of steel surfaces prior to painting.
4.2 Two methods for visual standards have evolved be cause of differences in the practice of using visual standards throughout the world. In Europe, the visual standards (Method A) are used as the primary means of determining the degree of cleaning. In the US, the SSPC written defini tions take precedence with the visual standards used as a supplement. The visual standards of Method B comply with the SSPC definitions.
5. Procedure and Interpretation
Method A--ISO/Swedish Standard
5.1 Determine the method of cleaning to be used (for example, hand/power tool cleaning, abrasive blast cleaning, or flame cleaning).
5.2 Determine the initial condition of the steel in accor dance with four initial grades (A, B, C, or D).
5.3 Following the cleaning operation, compare the surface prepared with the photographs showing the degree of thor oughness for that particular initial condition. Select the degree that most closely corresponds to the prepared surface.
5.4 Repeat the procedure for representative areas of structure and record all three items (initial condition, method of cleaning, and degree of thoroughness achieved).
Method B, SSPC Visual Standard
5.5 Determine the degree of blast cleaning to be em ployed.
5.6 Determine the initial condition of steel in accordance with photographs A, B, C, and D.
5.7 Following the cleaning operation, compare the pre pared surface with the photographs showing the degree of thoroughness for that particular initial condition. Select the degree that most closely corresponds to the prepared surface.
5.8 Repeat for all representative areas of structure and record for each area the initial condition and degree of thoroughness achieved.

houses. Specified panels may be obtained from standard panel suppliers.
3:2 The zinc coating shall have been applied by a contin uous galvanizing method, using an aluminum-bearing zinc. Galvanized steel is customarily shipped from the mills unoiled; however, galvanized steel that has been oiled with a nonreactive rust preventative oil shall be acceptable under this specification.
3.3 After cutting, the panels shall be cleaned in organic solvents or vapor degreased and wrapped in clean paper having a neutraFpH and sealed in vappiproof bags or envelopes. The use of alkali cleaners shall not be permitted. The panel size shall be not less than 23A by 5% in. (70 by 150 min) and all comers and edges shall.be smooth and uniformly rounded.
4. Solvents and Reagents
4.1 Solvent Mixture--Prepare a solvent mixture con sisting of either equal volumes of Varnish Makers' and Painters' (VM&P) naphtha and xylene or of 3 volumes of VM&P naphtha and 1 volume of ethylene glycol monoethyl ether (2-ethoxyethanol).
4.2 Stabilized Trichloroethylene or Perchloroethylene.
N45' 2--Perchloroethylene and trichloroethylene shall conform to and be maintained in accordance with the Federal Specification for Trichloroethylene (0-T-634a Type II) or Perchloroethylene (0-P-191a).
5. Procedure A--Galvanized Steel Test Panels Without Chemical Treatment
5.1 Wipe the corrosion-free panels vigorously on both sides with a cloth wet with the solvent to remove the gross film of oil. Clean the panels by either solvent spray or vapor degreasing, as described in 4.2 and 4.3.
5.2 Solvent Spray Cleaning--Spray the solvent mixture (3.1) downward at an acute angle to the panel surface using a spray gun operated with the fluid tip wide open and the atomizing tip almost completely closed. Preferred practice is to support the panels on a rack at an angle of approximately 25 from the vertical and to hold the spray gun so that the jet is directed vetically downward. The bottoms of the panels should rest upon projections, such as nails, which permit the solvent to drain from the bottom edge. Direct the solvent over the surface of the panel in an oscillating rinsing manner, moving the spray progressively from the top to the bottom of the panel until all soluble and loosely adhering soil has been washed off. The minimum treatment shall consist of five

washings, three on the side to be tested, and two on the reverse aide. Alternate the washings, starting and ending with the side to be tested. Allow the panels to dry at room temperature until all solvent has evaporated (approximately 15 min). Then rub the panels briskly with a clean, lint-free cloth to remove any adhering dirt or smut. Place the panels in an oven and uniformly heat at 350F (177C) for 10 min. After heating, remove the panels from the oven, allow them to cool to room temperature, and coat them immediately with the paint system (Note 3). Do not touch the panels with the fingers during the entire process of preparation.
N67' 3--Unpainted panels that have been stored for long periods may cause fine blisters to form on paint, usually at the zinc spangle boundaries, and baking the panel as described eliminates this blistering.
5.3 Vapor Degreasing--Suspend the panels in a vapor phase-type degreaser containing stabilized trichloroethylene or percMoroethylene and allow them to remain above the boiling solvent until they attain the temperature of the vapor, at which time condensation on the panels no longer occurs. Allow the panels to cool to room temperature and rub briskly with a clean, lint-free cloth. Place the panels in an
oven and uniformly heat at 350F (177C) for 10 min. After heating, remove the panels from the oven, and allow them to cool to room temperature and coat them immediately with the paint system (Note 3), Do not touch the panels with the fingers during the entire process of preparation.

sanding or abrasion, in accordance with Procedure A. Coat :
the panels with b phosphate coating or other conversion
coating representative of production performance (Note 4),
The conditions of treatment shall be agreed upon between
the manufacturer and the purchaser. Paint the treated panels

5. Conditions Affecting Traffic Paint
5.1 Practical requirements for traffic paint may vary with: 5.1.1 Substrate type, such as Portland cement and as phaltic concretes, and the various coarse aggregates used therein. 5.1.2 Climatic conditions, both generally and specifically, at the time of paint application.
5.1.3 Service density, such as heavy traffic areas in cities versus lightly traveled rural highways and parking lots.
5.1.4 Traffic type, whether light passenger cars or heavy trucks and airplanes.
5.1.5 Presence of foreign matter on the road surface, such as oil, old paint, skid marks, sand, salt, concrete curing compound, etc.
5.2 New Portland cement concrete surfaces have a greater degree of moisture and alkalinity than older surfaces and thereby adversely affect paint adhesion. Paint adhesion is also affected by the ratio of cement to fine aggregate, coarse aggregate, and mixing water, as well as by the surface character of the aggregate that can range from impervious smooth quartz to irregular, porous slag.
LIQUID PAINT PROPERTIES
6. Skinning
6.1 Paints containing a binder that dries by oxidation are subject to skin formation in a partially filled can or by diffusion of air into a filled can. Since skins are insoluble in the paint they must be removed before use. The referenced test employs a partially filled container to indicate the tendency of a paint to skin. A typical minimum time for skinning is 18 to 24 h.
6.2 Examine the original sample for skins both on the surface and in the mass. Using a well-mixed, skin-free portion of the sample, perform a skinning test in accordance with Guide D 154, except use a 1-pt (0.5-L) friction-top can instead of an- 8-oz (0.25-L) jar.
7. Coarse Particles
7.1 Paints must be free of oversize particles and foreign matter to avoid dogging application equipment, a typical maximum being i % by weight of total paint. The referenced test with a 325-mesh (45-p.m) screen gives the percent of this material in the paint.
7.2 Determine coarse particles in accordance with Test Methods D 185.
N<=' 1--This test is not used for traffic paint containing pre-mixed
glass beads.
8. Fineness of Dispersion
8.1 The more finely a pigment is dispersed, the more efficiently it is being used. One method for measuring the degree of dispersion (commonly referred to as "fineness of grind") is to draw the material down a calibrated, tapered groove in a hardened steel block with the groove varying in
depth from 4 to 0 mils (100 to 0 pm). The point at which continuous groupings of particles or agglomerates, or both protrude through the surface of the liquid is taken as the fineness reading. Lower readings in mils or micrometres or | higher reading in Hegman units indicate better fineness of ' dispersion.
8.2 Fineness of grind is not generally specified for traffic paint but some application equipment may require a limit of 1 to 2 Hegman units (3 to 3.5 mils, 75 to 90 pm), if additional assurance is needed that the paint will not clog application equipment, determine the fineness in accordance with Test Method D 1210 after reducing the traffic paint with mineral spirits, or compatible aromatic solvent with a similar evaporation rate, to keep the film wet long enough to determine the end point more easily. When a premix traffic paint is being tested, conduct the test on the paint before addition of the beads.
9. Density or Weight per Gallon
_ 9.1 Density as measured by weight per unit volume is not a performance characteristic but is used to check product uniformity from batch to batch. A calibrated weight per gallon cup is used.
9.2 For an unbeaded paint, determine the density in accordance with Test Method D 1475.
9.3 For beaded paints, use a special weight-per-gallon cup7108having a modified cap so that the beads do not interfere with a snug fit of the cap to the cup. Proceed in accordance with Test Method D 1475.
10. Consistency
10.1 Paints of a given type should fall within a stated consistency range as agreed upon between the purchaser and the seller. Consistency is used mainly to ensure product uniformity. Improper consistency, however, can adversely affect application properties, and in turn, paint performance.
10.2 Determine consistency using the Stormer viscometer in accordance with Test Method D 562. If the requirement is in Krebs units, Table 1 of Test Method D 562 permits changing seconds to KU.
11. Package Stability
11.1 Since paints are not normally used immediately after manufacture, they must remain stabje in the can for some time, which for traffic paints does not generally exceed 6 months. Although package stability can usually he deter mined by alternatively heating and cooling a specimen, occasionally the results do not coincide with storage at normal temperature. The referenced methods determine the degree of pigment settling after 2 weeks cycling or after 6 months storage at room temperature. These are usually sufficient as it is difficult to rate numerically the ease of redispersing an aged traffic paint.
11.2 Determine the degree of pigment settling in the accelerated test in accordance with Test Method D 1309. Determine the degree of pigment settling and ease of

actual exposure so that the test detects only paints with poor water resistance.
20.2 Using unbeaded paint, determine water resistance in accordance with either Practice D870 or Test Methods D 1647.
20.3 As Practice D 870 specifies steel panels but not the immersion time, while Test Methods D 1647 requires tin plate and an immersion of 18 h, the following should be used fortesting traffic paint: apply a 5-mil (130-pm) wet film to a clean glass panel, allow to air dry for 72 h, immerse in reagent water for 24 h, and allow a recovery period of 2 h before examining.
ANALYSIS OF PAINT
21. Chemical Analysis
21.1 If a specification requires certain raw materials or certain components in a given amount, then chemical analysis is necessary to determine whether the specified materials are present in the required amounts. Analysis does not necessarily establish paint quality that can also be greatly affected by manufacturing techniques. Select test procedures from Methods D2I5 and other ASTM methods that are pertinent to the components of traffic paints.
N>?' 2--No single schematic analysis is comprehensive enough to
cover the wide variety of traffic paint compositions.
22. Nonvolatile Content (Paint)
22.1 The percent nonvolatile matter indicates the amount of material remaining after the solvent evaporates and is a measure of the film solids. Determine the nonvolatile content in accordance with Test Methods D 1644 using a larger specimen size in the case of beaded paint. It is suggested that the methods be selected as follows:
22.1.1 Test Method A--3 h at 105C for paints where the nonsolvent components decompose at 149C, and
22.1.2 Test Method B--10 min at 149C for most paints where the nonsolvent components are reasonably stable at 149C.
23. Pigment Content
23.1 Pigment gives paint its hiding and color and influ ences many other properties. Determine the percent pigment in accordance with Test Method D 2371.
24. Binder Content
24.1 The nonvolatile vehicle is that portion of the filmforming solids in a paint other, than the pigment. It is not to be confused with the nonvolatile portion of the vehicle. Subtract the pigment content from the nonvolatile content to obtain the nonvolatile vehicle content. Ifdesired, separate the vehicle for further analysis in accordance with Method D2372.
FIELD EVALUATIONS
25. Road Service Test
25.1 Whereas numerous laboratory tests in the previous
sections indicate general suitability of traffic paint, and also batch-to-batch uniformity, these tests cannot predict per. formance under all possible end uses. Accordingly, the test paint should be applied in a repeatable manner under carefully stated conditions of end use and then tested observed, and evaluated at stated times throughout the usefoj life of the paint
25.2 Proceed in accordance with Practice D713, being careful to record the value of each variable stated.
26. Retroreflectance
26.1 Since there is no acceptable instrumental method of evaluating the retroreflectance in the field of the glass spheres on (in) the traffic paint stripe (Note 4), the following two visual methods are extensively used: (/) rating longitudinal stripes from a car traveling at approximately 20 to 35 mph and requiring a test line 50 ft (15 m) long, and (2) rating transverse test stripes in the wheel tracks with tungsten illumination from' the side of the road with eye and light source (held chest high) and separated by a distance that corresponds to the observation angle of a driver viewing the stripes on a highway.
26.1.1 These ratings are based on a scale of 10 (complete (100 %) retroreflectance) to 0 (no retroreflectance).
N@A' 3--The wheel track is the area extending 9 in. (230 mm) to
each side of the point of greatest wear.
N@A' 4--An instrumental method with much greater precision &
being developed.
27. Durability
27.1 The test line rating is based on the paint film remaining at the time of inspection when estimated by dose observation with the unaided eye. The rating is on the scale from 0 to 10, the latter representing 100 % remaining, a rating of 9 representing 90 % remaining, etc.
28. Appearance
28.1 This is the complete impression conveyed when the test stripe is viewed at a distance of at least 10 ft (3 m). Any discoloration of the surface due to bleeding, dirt collection, darkening, fading, mold growth, etc. will affect the rating
that is also on the scale from 10 to 0.
;
29. Length of Useful Life
29.1 The length of useful life is the length oftime (in days)
between application of the test fines and when the weighted rating first reaches a value of 4, or when any specific quality (appearance, durability, or night visibility) first reaches the numerical rating of 3, whichever is the lesser number of days.
29.2 When it is necessary to calculate the "length ofuseftil life," calculate as follows (Practice D 713):
L = D x (10 -- 4)/(10 - R) = 6D/(10 - R)
)
where: L = length of useful life, D -- number of days the test stripe has been on the road,
and R = weighted rating at time of calculation.

This test method originally resulted from the consolidation ofa number of separately published methods for the instrumental evaluation of color differences. As revised in 1979, it included four color spaces in which color-scale values could be measured by instruments, many of which were obsolete, and the color differences calculated by ten equations for different color scales. The sections on apparatus, calibration standards and methods, and measurement procedures served little purpose in the light of modem color-measurement technology. The present revision omits
these sections, and limits the color spaces and color-difference equations considered, to the three most widely used in the paint and related coatings industry.
1 ; ;
1. Scope
1.1 This test method covers the calculation, from instru mentaily measured color coordinates based on daylight illumination, of small color differences between nonfluorescent, nonmetameric, opaque specimens such as painted panels. (Where it is suspected that the specimens may be metameric, that is, possess different spectral curves though visually alike in color, Practices D 1729 and D 4086 should be used to verify instrumental results.) The color differences determined by these procedures are expressed in terms of approximately uniform visual color perception in CIE 1976 CIELAB opponent-color space (l),2 Hunter LH, a^, bH opponent-color space (2), and the Friele-MacAdam-Chickering (FMC-2) color space (3).
1.2 For product specification, the permissible color differ ence between test specimen and reference and the procedure for calculating the color difference shall be agreed upon by the purchaser and the seller. Specific color tolerances may be required for each material and condition of use since other appearance factors (for example, proximity, gloss, and tex ture) may affect the correlation between the magnitude of a measured color difference and its commercial acceptability.
1.3 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish

Summary of Test Method
4, l The differences in color between a reference and a test specimen are determined from measurements made by use 0f a spectrophotometer or a colorimeter. Reflectance read-
from such instruments are converted by computations color-scale values, or these color-scale values may be read directly from instruments that automatically make the imputations. Color-difference magnitudes are computed, j.0m differences in these color-scale values, that represent jpc perceived color differences between the reference and the test specimen.
3, Significance and Use
5.1 The original CIE color scales based on tristimulus values X, Y, Z and chromaticity coordinates x, y are visually nonuniform. Each subsequent color scale based on CIE values has had weighting factors applied to provide some degree of uniformity so that color differences in various regions of color space will be more nearly comparable. On the other hand, color differences obtained for the same specimens evaluated in different color-scale systems are not likely to be identical. To avoid confusion, color differences among specimens should be compared only when they are obtained for the same color-scale system. There is no simple factor that can be used to convert accurately color differences in one system to differences in another system for all colors of specimens.
5.2 For uniformity of practice, the CIE recommended in 1976 the use of two new improved color scales, of which the CIELAB scale, with its associated color-difference equation, has found wide acceptance in the coatings and related industries. However, it has not completely displaced the use of the Hunter LH, aH, bH and the FMC-2 scales, which are still utilized to allow comparison with earlier results and because of their familiarity to those responsible for inter preting them. Therefore, all three scales are included in this method as the most widely used in industrial laboratories..
5.3 Users of color differences have found that, in each system, summation of three vector color-difference compo nents into a single scalar value is useful for determining whether a specimen color is within a specified tolerance from t standard. However, for control of color in production, it is tecessary to know not only the magnitude of the departure
a standard but also the direction of this departure. Information on the direction of a color difference is easily included by giving the three instrumentally determined w>mponents of the color difference.
5.4 Selection of color tolerances based on instrumental 'dues should be carefully correlated with a visual appraisal
the acceptability of differences in hue, lightness, and saturation obtained by using Practice D 1729.
Description of Color-Difference Equations
6.1 CIE 1931 and 1964 Color Spaces--The daylight
colors of opaque specimens are represented by points in a space formed by three rectangular coordinates representing the lightness scale Y and chromaticity scales x and y, where:
X x~X+V+Z
Y ymX+T+Z
Y= Y
where X, Y, and Z are tristimulus values for either the 1931 CIE standard observer (2observer) or the 1964 CIE supple mentary standard observer (10 observer) and standard illuminant C, D6S, or another of daylight quality. These scales do not provide a perceptually uniform color space! Consequently, color differences are seldom if ever computed directly from differences in x, y, and Y.
6.2 CIE 1976 L* a* b* Uniform Color Space and ColorDifference Equation (1, 4>--This approximately uniform color space' is a simplified version of the Adams-Nicker$oii color-scale system (5-7), It is produced by plotting in rectangular coordinates the quantities L*, a*, b*, calculated as follows:
1* = ii6(y/y,,)`A- 16 a* = SQ0[{XjX,,)'h - (Y[Y,,n b* = 200107 - {ziznr\
X/Xn; Y/Y,,; ZjZn > 0.01
The tristimulus values X,,, Y,,, Zn define the color of the normally white object-color stimulus. Usually, the white object-color stimulus is given by the spectral radiant power of one of the CIE standard illuminants, for example, C, D6S or another of daylight quality, reflected into the observers eye by the perfect reflecting diffuser. Under these conditions, X,,, Y,,, Z,, are the tristimulus values of the standard illuminant with Y,, equal to 100.
6.2.1 The total difference AE%, between two colors each given in terms of L*, a*, b* is calculated as follows:
AE% =[(AI*)2 + (Aa*)2 + (Ab*?f>
NJK' 1--The color space defined above is called the CIE 1976 L*
a* b* space and the color-difference equation the CIE 1976 L* a* b* color-difference formula. The abbreviation CIELAB is recommended.
6.2.2 The CIE 1976 (L* a* b*) space fails to approximate uniform color spacing when one or more of the ratios xjxm Y/Y,,, and Z/Z,, is less than 0.01. In calculating L*, values of Y/Y,, less than 0.01 may be included if the normal formula is used for values of Y/Y,, greater than 0.008856, and the following modified formula is used for values of Y/Y,, equal to or less than 0.008856.
l * = 903.3( y/ y,,) y/ y,, < 0.008856
6.2.3 In calculating a* and b*, values of XjX,, Y/Y,,, ZfZ,, less than 0.01, may be included if the normal
equations are replaced by the following modified equations for ail calculations of a* and b*:
a* = 500[/OTO -f(Y/Yn)] b* = 200[/(y/y,,)-KZjZfo
where:
f{X/X,,) = {XjX^ '
f{X/X,,) = 7.7i7(X/X,,) + 16/116 f(Y/Yn) = (y/y,,r

'7/7,, <0.008856 Z/Z,, > 0.008856 Z/Z,, 0.008856
NLM' 2--To compare values of A.E(.4/V40) calculated by means of
the Adams-Nickerson (+A'40) equation with AE*^, multiply AE(AN40)
values by the factor 1.1 to facilitate the comparison.
6.2.4 The magnitude, AE*ab, gives no indication of the character of the difference since it does not indicate the relative quantity and direction of hue, saturation, and lightness differences.
6.2.5 The direction of the color difference is described by the magnitude and algebraic signs of the components AL*, Aa*, and A b*:
AL* = Lf - IS
Aa* = at - a* Ab* = b* -- b%
where L?, a% and b% refer to the reference, and L%a*, and b* refer to the test specimen. The signs of the components AL*, Aa*, and Ab* have the following approximate meanings (8):
+AL* = lighter -AL* = darker +Aa* = redder (less green) -Aa* = greener (less red) +Ab* = yellow (less blue)
-A* = bluer (less yellow)
6.2.6 For judging the direction of the color difference between two colors, it is useful to calculate their CIE 1976 hue angles hab and CIE 1976 chromas C*b as follows:
hab = tan~`(b*/a*) C*ab = [(a*)2 + (b*f]Vi
Differences in hue angle Ahab between the test specimen and reference can be correlated with differences in their visually perceived hue, except for very dark colors (9). Differences in chroma AC** can similarly be, correlated with differences in visually perceived chroma.
6.2.7 For judging the relative contributions of differences in lightness, chroma, and hue to the total color difference between two colors, it is useful to calculate the CIE 1976 hue difference AH*h between them as follows:
AH*h = [(AE*abf - (AL*)2 - (AC**)2]*
where AE*b is calculated as in 6.2.1 and C%b is calculated as in 6.2.6; then the equation
AEL = [(AL*)2 + (A C*abf + (AHLfl
contains terms showing the relative contributions oflightness difference AL*, chroma difference AC*b, and hue difference AH*b to the total color difference AE%b.
6.3 Hunter LH, aH, bH Color Space and Color-Difference Equation (2)--This approximately uniform color space is produced by plotting in rectangular coordinates the quanti ties L/f, alf, bH calculated as follows: ., .
L// = 10( 7)Vl aH= 17.5(1.02Z- Y)j( Y)'h bH = 7.0( Y -- 0.847Z)/(7)l/!
where X, Y, and Z are tristimulus values for the CIE 1931 standard observer and standard iUuminant C........................
NNO' 3--The subscript L was used to denote Hunter in previous
issues of this method.
6.3.1 The total difference AEh between two colors each given in terms of LH, a,,, b,, is calculated as follows:
AEh = i(AL,,)2 +
+ (4iw)f
6.3.2 The magnitude and direction of the color difference are described by considerations similar to those found in 6.2.4 and 6.2.5, respectively.
6.4 Friele-MacAdam-Chickering Color Space and ColorDifference Equation (3,10)--This color space is more nearly perceptually uniform than the CIE 1931 space in terms of

6. Test Specimens
6.1 The test specimens shall be either samples of metallic products, prepared and coated in accordance with the specified production schedule, or coated metallic panels. The recommended panel size is 4 by 12 in. (100 by 305 mm).
7. Preparation of Test Specimens
7.1 The test specimens shall consist of steel meeting the requirements of Methods D 609, cleaned and prepared for coating in accordance with Procedure A of Method D 609. If desired, the metal panels selected for coating with organic coatings may be of any selected composition and may be cleaned and prepared according to commercial practice or by any procedure that is mutually agreed upon.
7.2 After coating, the specimens shall not be cleaned, and they shall be handled only by the edges.
8. Procedure
8.1 Support panels or specimens so that they will be held in a position 0 to 30from the vertical in such a manner as to prevent contact between the panels during the test.
8.2 Place the panels in a humidity cabinet at 100F (38C) and 100 % relative humidity for a period of 24 lA h. Then transfer them to the cold box at --10 3F (-23 1.5C) allowing a maximum of 30 s for the transfer. Leave the panels in the cold box for a period of 20 + 'h h. Remove the panels and allow to remain at room temperature for a period of 4 Va h, during which time rate them. This constitutes one cycle. Run the test for 15 cycles or as mutually agreed upon. During any interruption of the normal cycling, as on weekends, always leave the panels in the cold box.
9. Evaluation of Test Specimens
9.1 Lay the specimen upon a horizontal surface, finish side up, with the framed grid (5.4) placed upon it so that the bottom 8i/2 in. (225 mm) is covered by mesh. (The frame itself excludes the first l/2 in. (13 mm) from edges of the specimen which may have been handled, or which may otherwise not be representative ofthe general area.) Make an evaluation by counting the number of grid squares within which one or more cracks is visible. This number shall constitute the rating.

-.5. Summary of Practice
3.1 Coated specimens are placed in an enclosed chamber containing a heated, saturated mixture of air and water vapor. The temperature of the chamber is usually maintained at 100F (38C). At 100 % relative humidity (RH), a very small temperature difference between the specimen and the sur rounding vapor causes the formation of condensation on the specimens. The exposure condition is varied by selecting the duration ofthe test. Water permeates the coating at rates that are dependent upon the characteristics of the coating. Any effects such as color change, blistering, loss of adhesion, softening, or embrittlement are observed and reported.
4. Significance and Use
4.1 Water can cause the degradation of coatings, so-knowledge of how a coating resists water is helpful in predicting its service life. Failure in tests at 100 % relative humidity may be caused by a number of factors including a deficiency in the coating itself, contamination of the substrate, or inade quate surface preparation. This practice is therefore useful for evaluating coatings alone or complete coating systems.
4.2 Tests at 100 % relative humidity are used for specifi cation acceptance, quality control, and research and devel opment of coatings and substrate treatments. These tests usually result in a pass or fail determination but the degree of failure may also be measured. A coating system is considered to pass if there is no evidence of water-related failure after a period of time.
4.3 Results obtained from the use of 100 % humidity tests in accordance with this practice should not be represented as being equivalent to a period of exposure to water in the natural environment, until .the degree of quantitative corre lation has been established for the coating or coating system.
4.4 The test chamber can be a small laboratory cabinet or a room large enough to hold an automobile or a truck. Some automobile Manufacturers test completed vehicles in rooms maintained at 100 % relative humidity. Corrosion tests can be conducted, as the condensate dripping off the test articles is not recirculated.

5.5 Diagrams and details of the apparatus are shown in the Annex.
6. Test Specimens
6.1 This practice does not cover the preparation of test specimens. The substrate composition and surface prepara tion, specimen preparation, and the number of specimens should be agreed upon prior to testing.
N[\' 2--Applicable methods for the preparation of test panels and
substrates are given in Method D 609 and Practices D 1730. Test Methods D823 cover application techniques for the production of uniform films.
7. Procedure
7.1 Fill the water tank with reagent water conforming to
Type TV of Specification D 1193. Tap water may be used,
but this will result in the accumulation of residues in the
water tank over a period of time.
7.2 Adjust the temperature of the saturated air and water
'apor mixture to 38 1C (100 IT).
"*
N]^' 3--Due to heat loss to the specimens and the walls of the
tamber, the temperature of the water in the tank will .be above the mperature of the air and water vapor mixture.
7.3 Support the specimens approximately 15 from the rtical. Slotted wood supports are suitable for flat speciens. Provide for formation of condensation on the speci
mens by spacing them at least 30 mm apart. Space the specimens so they do not touch each otheF, any metallic material, or any material capable ofacting as a wick. Arrange specimens so that condensate from one specimen cannot drip on other specimens.
7.4 Droplets of condensation should be visible on the specimens at all times if the chamber is operating properly. Operate the test continuously with the test chamber closed unless otherwise specified. Short interruptions to inspect or remove specimens are permitted.
7.5 Conclude the test after a specified period of time or after effects from exposure to water are observed.
7.6 Wipe the test specimens dry. Rate specimens for changes in color, blistering, etc. Evaluate specimens no less than 5 min and no more than 10 min after removal from test, as the effects from water exposure can change within a short time. Remove only as many specimens as can be rated within the specified time.
N_`' 4--The 0 to 1.0 scale described in ASTM STP SOO6 is preferred
for rating. Relevant procedures foe evaluating water effects are described in Test Methods D 610, D 714, D 2616, D 3359, and D 3363.
7.6.1 If possible, rate the specimens again after they have been removed from the test for a recovery period long enough that moisture absorbed within the specimens dries out and the specimens reach moisture equilibrium with room air. A recovery period from 12 to 24 h is generally sufficient. The post-recovery rating allows evaluation of the permanent effects of the exposure as distinct from the transient effects, and is especially important for evaluation of color and gloss.

The use of a large heated water tank would tend to make the temperature within the chamber uniform, and thus inhibit or prevent the formation of condensate on the specimens. The water temperature will be approximately from 10 to 20F (5 to 10C) above the vapor temperature when the water tank and chamber are properly proportioned.
A 1.3 Insulation of the enclosure is not required and can
possibly interfere with the formation of condensate by reducing the temperature differential within the chamber. It is difficult to produce condensation with small chambers because the temperature differential is slight.
A1.4 Large walk-in chambers may require more than one heated water tank to generate the convective currents needed to cause condensation at all points within the chamber. Circulating fans should be used with caution as their use may reduce the temperature differential and limit condensation.
A1.5 In a properly operating chamber, condensation is observed on the specimens or parts when the chamber is opened for inspections. It may be necessary to avoid placing specimens in the lower portion of the chamber as the temperature differentials at the lower levels may be too small to induce condensation.
A 1.6 In the event that enough condensation does not occur, or condensation does not form at all the desired points, it is possible to increase condensation by:
Al.6.1 Opening the chamber to allow the temperature to drop,
Al.6.2 . Turning off the water heater periodically to cause temperature fluctuations, or
A 1.6.3 Removing the specimens to allow them to cool
down to room temperature.
A 1.7 Many variations in the design of the apparatus are possible in the use of this practice. Two typical designs are shown in Figs. AI.l and Ali2.

A suggested temperature of the detergent solution is 165
2'F (74 1"C).
g_ procedure
g,l Immersion--Suspend the test specimens vertically in ^ container so that at least one half of the surface area is ' submerged in the detergent solution. Separate the test specimens so that they are not in contact with any metal and jj-e no closer together than 1 in. (25 mm) at any point in the bath- Replace the detergent solution with fresh detergent solution every 168 h. If successive tests are to be correlated, ^ reference panels coated with a control paint.
3.2 Examination ofSpecimens--When the specimens are jgady for examination, carefully remove, gently wash or dip in clean running water not warmer than the temperature of the detergent solution to remove the detergent from the surface, and then carefully dry by blowing with air or blotting with absorbent paper. During the progress of the test, examine for deterioration of the film immediately. If reimmersion is necessary, do not allow the specimens to rcmain out of the liquid in excess of Vz h, unless otherwise specified. Examine the test coating for the failures specifi cally agreed upon by the purchaser and the seller.
Ngh' 3--The following methods of evaluating finish degradation in this method are applicable:
Test Methods D523, D7I4, D 1474, and D2197, and Methods D 610, D 1-654, and D 2244.
8.3 Length of Test--The length of test and the interme diate examination periods shall be as designated by the specification covering the organic finish being tested or as mutually agreed upon by the purchaser and the seller.
9. Precision and Bias
9.1 Precision data are based on a round robin in which
three finishes applied to two substrates were tested in six
laboratories with each laboratory making two runs of five replicates of each-variation. Blister failure was reported by all cooperators using Test Method D714. To simplify the evaluation of blistering data the blister ratings were con verted to single numerical values by the formula Frequency Number x Size -s- 10 = Numerical Value. The Frequency Numbers assigned were as follows:
No blistering Very few Few
Few medium Medium Medium dense Dense
to 9 8
6 S 4 2
By this system, few Size 8 blistering would have a numerical value of 6.4. The adequacy of precision depends upon the
purpose of the test and should be determined by die user from the data supplied.
9.1.1 Using these numerical values the standard devia tions for the three finishes were as follows (rounded to nearest-tenth):

4. Characteristics in the Package
4.1 Skinning, Settling, and Condition in the Container: 4.2 Settling is determined in accordance with Test Method D869, and by Federal Test Method No. 141b, Method 3011 which also covers condition in the container, goth of these methods are designed for trade sales type paints father than industrial coatings, but could be adapted satisfac
torily.
4.3 Skinning can occur in a partially filled container.
Remove insoluble skins and perform a skinning test on a
well-mixed portion in accordance with Guide D 1541
4.4 Consistency--Consistency of a paint varies consider
ably depending upon the type ofinstrument used to measure
it. Consistency is determined in accordance with Test
Method D 562 and Test Method D 1200. For most coatings
therer is not a straight line relationship between Stonner
viscosity, a rotational method, and Ford cup viscosity, an
efflux method. (The Zahn efflux cup and the Brookfield
Rotational Viscometer (Test Methods D 2196) are also used
widely by the paint industry.)
4.4.1 Most factory wood finishing is done with airless
spray, curtain coating, or roller coating techniques. It is
doubtful that any single method of viscosity measurement is
truly indicative of the ability of coatings to be applied by
production methods or, more especially, to be applied,
satisfactorily by curtain coating.
4.4.2 These methods are useful in that once a certain
formula has been established, control of the viscosity by
either method helps to ensure subsequent reproduction of
that formula. In this way, they would be useful in specifying
previously qualified coatings for factory finishing of wood
products.
4.5 Fineness of Dispersion--The fineness of dispersion
determined in accordance with Test Method D 1210, is
based on visual observation of a few of the largest size
particles remaining in a .coating after dispersion. In itself, the
test does not indicate the degree of dispersion of the bulk of
the pigment in the coating except that when batches are
dispersed in similar equipment the ratio of large particles
remaining in the coating to the dispersion of the bulk of the
pigment tends to remain constant Therefore, if in an enamel
with satisfactory gloss no particles remain that are above a
size of 0.5 mil (7 Hegman dispersion), then successive
batches of that coating having a similar Hegman rating can
be said to have a good enamel grind. Hiding power and color
control along with fineness of dispersion control should be
adequate to ensure proper dispersion.
4.6 Weight per Gallon--Weight per gallon is determined
in accordance with Test Method D 1475 to ensure batch-
to-batch and composition product uniformity. This method
is not related to the quality of the coatings per se.
4.7 Nonvolatile Content--Non-volatile content is deter
mined in accordance with Test Methods D 1644 as another
measure of coating uniformity and of the amount of
film-forming material provided.
4.8 Volatile Organic Content (VOC)--VOC is determined
in accordance with Practice D 3960 both to ensure coating
uniformity and to comply with governmental regulation
where required.
............ _................ ....
4.9 Flash Point--Flash point is determined in accordance
with Test Methods D 3278 as a measure of the degree of
flammability or fire hazard of a coating material.
5. Coating Characteristics During and Immediately After Application
5.1 Flow--Flow is a property related to consistency, but it is influenced by other factors such as rate and order of solvent release. Visual observation of the leveling ofa coating film during and after drying and the tendency of the film to sag during application and drying are usually adequate to determine flow. However, Test Method D 2801 may be used if desired.
5.2 Gloss--Specular gloss may be determined in accor dance with Test Method D 523.
5.3 Hiding Power--Hiding power determined in accor dancewith Test Method D 2805 is a measure of the ability of a paint to hide the substrate. It is dependent upon uniform film thickness which is influenced by flow and leveling.
5.4 Wet Film Thickness--The thickness of a wet paint film is determined in accordance with Test Methods D 1212 as a rapid indication that the required amount of coating has been applied.
6. Coating Characteristics During and Immediately After Curmg
, 6.1 Curing Temperature--The temperature of a coating film during the curing cycle is an important quality control parameter and should be monitored. Practice D 3259, dis cusses several infrared measuring instruments that can be used for such monitoring. Infrared measuring instruments can be based on the measurement of carefully filtered narrow bands of infrared energy emitted from test surfaces and can be unaffected by surface color or gloss. Thermocouples have been used but are subject to the defects that metals are good heat conductors and do not necessarily absorb heat from infrared radiation at the same rate as the paint film. Better results are obtained with portable pyrometers if they are preheated slightly above the operating temperature. Papers impregnated with wax powders of varying melting points have been suggested also. These tend to absorb infrared energy faster than most wet paint films and, therefore, give higher temperatures than actual.
6.2 Film Thickness--Measurement of film thickness in accordance with Test Methods D 1005, is designed for use on plane rigid surfaces such as metal or glass. It can be adapted to forest products by the simple use of an auxiliary panel of metal or glass placed alongside the wood substrate and coated in the identical way that the wood substrate is coated. Test Methods D 1400 or D 1186 also could be adapted to the forest products industry in a similar manner. This is a simpler but perhaps less accurate method. This adaptation leads to a measurement of application rate rather than to a true measurement offilm thickness of the coating on a wood product because of the possibility of penetration by the coating into the wood product. Test Methods D 2691 gives a method for measuring the actual film thickness present on a wood products substrate.
6.3 Hardness--The measurement of hardness of coating films by means of an indenter, as described in Test Methods D 1474, calls for the measurement of film hardness on smooth, rigid substrates such as glass or metal. There may be some question as to its applicability on films applied to some
289
DUP050297472
D 2336
of the softer forest products substrates. However, ifthe films
are thick enough (1.5 mils or greater), it should be applicable
on the harder forest products substrate.
6.4 Color Difference--Color difference between a product
and the standard can be measured instrumentaUy. Generally,
the tolerance is agreed upon by the purchaser and the seller
and may also be required if a product specification is
involved. Although color instruments are not more sensitive
than the eye, and Practice D 1729 may be used for visual
evaluation of color differences, color instruments do provide
numerical values that can be subsequently compared to later
measurements. Test Method D 2244 covers the instrumental
determination of small color differences observable in day
light illumination between nonfluarescent, nonmetameric,
or opaque surfaces such as coated specimens. If metamerism
is suspected, visual evaluation should be used to verify the
results.
1
6.5 Adhesion--There are no available ASTM test methods
directly applicable to measuring adhesion on forest products substrates. It has been found that the available test methods have poor precision even on hard, smooth substrates. They would probably be even less satisfactory on wood substrates. Two methods that might give some indication of adhesion are Test Methods D 2197 and D 3359.
6.6 Blocking--Many coated wood products are immedi ately stacked after curing. Often they are subject to "blocking" or sticking together ifimproperly coated or cured. Test Method D 27937 may be used to detect and quantify the degree of blocking. It may be used as a control test to detect this condition during the coating operation.

superscript epsilon (<) indicates an editorial change since the last revision or reapproval.
1. Scope 1.1 This test method covers the determination of the ,ent to which multicolor lacquers resist coagulation and
coalescence when subjected to freezing and subsequent
thawing.
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is jjje responsibility of the user of this standard to establish appropriate safety and health practices and determine ike applicability of regulatory limitations prior to use.
2. Referenced Document
2.1 ASTM Standard: D 562 Test Method for Consistency of Paints Using the
Stormer Viscometer2
3. Summary of Test Method
3.1 Specimens of multicolor lacquers are placed in a chamber maintained at a temperature between -10 and -15"F (-23 and --26C) and allowed to remain 24 h. The specimens are removed from the chamber and allowed to remain at room temperature for 24 h to reach thermal equilibrium. After the specimens are mixed and the viscosity adjusted, they are then sprayed and allowed to dry before comparing with the control standard sprayed from the original specimen.
4. Significance and Use
4.1 Waterborne coatings, when subjected to cycles of freezing and thawing, can undergo detrimental changes in application and performance characteristics. This test method evaluates the ability of multicolor lacquers to resist these changes.
5. Apparatus and Materials 5.1 Cabinet, Room, or Enclosed Space, large enough to
contain the specimens to be tested and allowing at least i in. (25 mm) of air space between the sides of adjacent cans. It should be capable of being maintained at a temperature between -10 and -- 15F (--23 and --26Q.
5.2 Stormer Viscometer, with paddle-type rotor. 5.3 Spray Gun, pressure-feed internal-mix type, tip 0.086 in. (2 mm) in diameter with wide-spray nozzle.
' This test method is under the jurisdiction of ASTM Committee D-1 on Paint and Related Coatings and Materials and is the direct reponsibility of Subcom mittee 1301.55 on Factory-Applied Coatings on Preformed Products.

5.4 White Paper Stock, minimum size 8 by 11 in. (200 by 280 mm).
6. Preparation of Samples
6.1 For all gloss and semigloss multicolor lacquers, pre pare ten 1-qt (1-L) specimens and for flat multicolor lacquers four 1-qt specimens for testing. Mix the sample from which the specimens are filled well by boxing so that it is of a uniform consistency and appearance. After recording the consistency reading as determined with a Stormer viscometer , (in accordance with Test Method D 562 fill all samples in baked varnish-lined containers and apply the lids promptly to prevent evaporation loss).
7. Preparation of Control Standard
7.1 Prepare a control standard by spraying from one of the 1-qt (1-L) specimens of each product to be tested. Use a coated white paper stock and spray on a sheet at least 8 by 11 in. (200 by 280 mm) in size. Adjust the fluid and atomizing pressures to give a spreading rate of 150 to 200 ft2/gal (3.7 to 4.9 m2/L) for complete covering and 200 to 300 ft2/gal (4.9 to 7.35 m2/L) for scatter coat application.
8. Exposure of Samples to Test Conditions
8.1 Place nine specimens of all gloss and semigloss multicolor lacquers and three specimens of all flat multicolor lacquers under test in the chamber that is maintained between --10 and -- 15F (-23 and --26C). Place the specimens on racks in such a manner that they do not touch the walls or bottom of the chamber and so that there is at least 1 in. (25 mm) of air space between adjacent specimens. On each cycle allow all specimens to remain in the chamber for 24 h before removal. Remove from the chamber all specimens of each multicolor lacquer and let them come to thermal equilibrium by allowing them to remain at room temperature (77F (25C)) for 24 h. Mix these specimens to a uniform consistency by boxing. Run a minimum of three specimens and all specimens shall pass the test for multicolor to be acceptable.

9.1 Check the consistency of all specimens on the Stormer viscometer after each test cycle and adjust if necessary by adding water to the viscosity of the original before testing. Spray three specimens after each cycle on white paper stock using the same equipment and adjustments of the spray gun that were used to spray the control standard. Allow the sprayed panels to dry thoroughly (16 h) and compare with the control standard in each case for color, particle size, and pattern of the background as well as the accent colors.

5. Reference Standards
5.1 The photographic reference standards2 were prepared by photographing actual sprayed panels of multicolor lac quers that were made in the five particle sizes normally used in commercial multicolor lacquers. The standard designa tions are as follows (Figs. 1 (a), (b), (c)): fine, small, medium, large, and extra large, and represent the correct nomencla ture for properly applied multicolor lacquer.
6. Apparatus 6.1 Spray Gun, pressure-feed intemai-mix type, tip 0.086
in. (2.2 mm) in diameter with wide-spray nozzle.
7. Procedure
Nmn' --The particle size of multicolor lacquer is dependent upon the spray conditions during the application procedure. In order to get uniform results the exact spray conditions should be agreed upon between the purchaser and the seller.
7.1 Spray the lacquer on a coated white paper panel with the fluid and atomizing pressures adjusted to give a spreading rate of 150 to 200 ft2/gal (3.7 to 4.9 m2/L) for complete covering and 200 to 300 ft2/gal (4.9 to 7.35 m2/L) for scatter coat application. After the sprayed lacquer is thoroughly dry, determine the particle size on the panel by comparing it to the photographic reference standards.2
8. Precision
8.1 This test method entails the use of visual judgment and as such does not readily lend itself to a precision statement.
8.2 In general there has been good agreement between operators in judgment of particle size.

not to get any on the sides ofthe flask. Add approximately 10
boiling aids. 8.3 Digest by adding the following: 40 mL of HN03
(allow to stand 20 min) and 25 mL of H2S04 (allow to stand 5 min). Boil; when charring occurs, add HN03 cautiously until the solution becomes clear and begins to reflux within the flask. The flask should be at about a 45 angle while Higwring. Cool, carefully add 150 mL of water, and boil to
sulfur trioxide (S03) fumes. 8.4 Add 100 mL of water and a thermometer to an
Erlenmeyer flask. After the solution in the Kjeldahl flask has
codled, add 25 mL of water, 25 g of NaCl, and 25 mL of the hydrazine sulfate-potassium bromide solution, and connect the distillation tube so that the delivery end is immersed in the receiving water. Quickly heat the Kjeldahl flask over a small, well-protected flame, and distill into the Erlenmeyer flask (Note 1). Adjust the flame so that the temperature of the distillate solution will rise to 80C in 9 to 11 min, and then discontinue distillation by first removing the thermom eter, lifting the distillation tube out of solution slightly and turning the heat off.
Nqr' 1--Although it may be necessary to boil the solution, heating is primarily to bring about evolution of hydrogen chloride (HC1) gas,
which carries over the arsenic trichloride (AsC13). Absorption ofevolved HCI gas by water causes a rise in temperature which indicates progress of distillation. If distillation proceeds further, or if a larger quantity of H2S04 than specified is used in digestion, sulfur dioxide (S02) will be distilled and titrated as arsenic.
8.5 Titrate the distillate at once with KBrO, soluti,
using 3 drops of methyl orange indicator solution. TowaJ

Nop' 2--The blank titration should not exceed 0.7 mL of KBtQ
solution. The method is accurate down to variations in the blank, wyj should not exceed 0.1 mL when reagents from the same lot are used,6

5. Preparation of Sample
4.1 Mix and prepare the sample in accordance with Methods-D215.
6. Nature of Solvent
6.1 Transfer approximately 150 g of the paint to a 500-mL flask fitted with a 2-hole cork stopper carrying a spray trap connected with a suitable condenser. Through the other hole in the stopper pass an influx tube for steam. (This tube should dip below the surface of the paint.) Heat the flask in an oil or air bath at 100C and pass through it a current of steam; with the steam still passing through, raise the temperature of the bath to 130C. Catch the distillate in a small separatory funnel; continue distillation until 300 mL of water have been obtained. Portions of this water may be drawn from the cock of the separatory funnel from time to time, but care must be taken not to draw out any of the volatile solvent.
6.2 Let the distillate stand until it separates into two layers, then draw off the water and filter the volatile solvent through a dry filter paper into a dry flask. If the solvent is apparently turpentine, examine the distillate in accordance with Color, Odor, Specific Gravity, Refractive Index and Distillation sections of Methods D 233. If the solvent is a mixture of turpentine and petroleum spirits, an approximate determination of the amount of turpentine may be made in accordance with the Polymerization sections of Methods D 233. (It should be noted that turpentine is slightly soluble in water, about 0.3 to 0.4 mL/100 mL of water.)
6.3 To test for benzene, add a few drops of the distillate to a small quantity of a mixture of HN03 (sp gr 1.42) and H2S04 (sp gr 1.84) and heat cautiously. The characteristic odor of nitrobenzene wifi be noted if benzene is present.
Nst' 1--Toluene may give a similar odor,
6.4 If the solvent is apparently all petroleum spirits, no further examination is necessary unless further information is desired.
6.5 When the amount of turpentine in the solvent is so small that its presence is questionable, it may be detected by placing 2 drops of the distillate and 2 to 3 mL of chloroform in a dry test tube and adding 1 drop of SbCl5. A slow or slight change in color indicates the absence of turpentine. A rapid change in color to a dark red or purple indicates the possibility of turpentine. The iodine number for turpentine
297
DUPO 502 97480
# D2349
by the Wijs method under these conditions is approximately 340. An iodine number of 20 or over is additional proof of the presence of turpentine and enables calculation of the approximate amount.

Standard Test Method for Volatile Content of Coatings1
This standard is issued under the fixed designation D 2369; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reappraval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This test methodhas been approvedfor use by agencies ofthe Department ofDefense to replace Method 4041.1 ofFederal Test Method Standard No. 141. Consult the DoD Index ofSpecifications and Standardsfor the specific year ofissue which has been adopted by the Department ofDefense.
I Scope
ll This test method describes a procedure for the deter mination of the weight percent volatile content of solvent ajucible and water-reducible coatings. Test specimens are jjeated at 110 5C for 60 min.
Hf0TE i--The coatings used in these round-robin studies represented jj-dried, air-dried oxidizing, and heat-cured baking systems.
1.2 Sixty minutes at 110 5C is a general purpose'test method based on the precision obtained with both solventreducible and water-reducible coatings (see Section 9). These coatings (single package, heat cured) are commonly applied m factories to automobiles, metal containers, flat (coil) metal and large appliances, and many other metal parts.
Nuv' 2--Testing at 110 5"C for 20 min was utilized for the (Stablisbment ofthe original test, method in 1965. Precision data are not available and may not have been properly generated at the time. The nine paints tested then were all solvent-reducible. These conditions, 20 oin at 110 5C, are no longer satisfactory for the determination ofthe volatile content of many coatings being tested at the present time. Water-reducible and solvent-reducible coatings were tested in the development ofTest Method D 2369 using 110 5C for 60 min and 20 min for which precision data have been generated. See Appendix X1 for precision statements on the 20-min oven residence time.
1.3 This test method does not cover multi-package coat ings wherein one or more parts may, at ambient conditions, contain liquid coreactants that are volatile until a chemical reaction has occurred with another component of the multipackage coating.
Nwx' 3--Committee D-l is running round-robin studies on the volatiles of multicomponent paint systems. The only change in proce dure is to premix the weighed components in the correct proportions and allow the solvent reduced specimens in the aluminum pans to stand at room temperature for 1 h prior to placing them into the oven. Preliminary results with these changes appear to show that this test method is viable for multicomponent systems.
1.4 This test method may not be applicable to all types of coatings such as some printing inks (see Test Method D4713), and other procedures may be substituted with mutual agreement of the producer and user.
Nyz' 4--If unusual decomposition or degradation of the specimen occurs during heating, the actual time and temperature used to cure the coating in practice may be substituted for the time and temperature
specified in this test method, subject to mutual agreement of the producer and user.
1.5 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility ofthe user ofthis standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use. For a specific hazard statement see Note 6.

3. Summary of Test Method
3.1 A designated quantity of coating specimen is weighed into an aluminum foil dish containing 3 mL of an appro priate solvent, dispersed, and heated in an oven at 110 5C for 60 min, The percent volatile is calculated from the loss in weight.
4. Significance and Use
4.1 This test method is the procedure Of choice for determining volatiles in coatings for the purpose of calcu lating the volatile organic content in coatings under specified test conditions. The inverse value, nonvolatile, is used to determine the weight percent solids content. This informa tion is useful to the paint producer and user and to environmental interests for determining the volatiles emitted by coatings.

6. Reagents
6.1 Purity ofReagents--Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chem ical Society, where such specifications are available.8 Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination.
6.2 Purity of Water--Unless otherwise indicated, refer ences to water shall be understood, to mean Type II of Specification D 1193.
6.3 Toluene, technical grade, Specification D 362. 6.4 2-Ethoxyethyl Acetate, technical grade, Specification D 343.
7. Procedure
7.1 Mix the sample, preferably on a mechanical shaker or roller, until homogeneous. If air bubbles become entrapped, stir by hand until the air has been removed.
7.2 Using an appropriate weighing container (5.3, 5.4, or 5.5, with the syringe preferred for highest precision), weigh to 0.1 mg, by difference, a specimen of 0.30 0.10 g for coatings believed to have a volatile content less than 40 weight % or a specimen of0.50 0.10 g for coatings believed to have a volatile content greater than 40 weight %, into a tared aluminum foil dish (5.5) into which has been added 3 1 mL of suitable solvent (6.2, 6.3, or 6.4). Add the specimen dropwise, shaking (swirling) the dish to disperse the specimen completely in the solvent. If the material forms a lump that cannot be dispersed, discard the specimen and prepare a new one. Similarly prepare a duplicate.
N{|' 5--If the specimen cannot be dispersed in the solvents listed
(6.2, 6.3, or 6.4) a compatible solvent may be substituted provided it is no less volatile than 2-ethoxyethyl acetate (6.4).

XI. PRECISION STATEMENT FOR 20-MIN OVEN RESIDENCE
XI. 1 Oven residence time of 20 min for the paint test specimen at 110 5C was the original procedure for this
method. For information purposes, the precision state ments for 20-min residence time are as follows:
XI. 1.1 The precision estimates are based on an interlabo^tory study in which 1 operator in each of 15 laboratories jpalyzed in duplicate on 2 different days 7 samples of water-based paints and 8 samples of solvent-based paints containing from 35 to 72 % volatile material. The paints were commercially supplied. The results were analyzed statistically in accordance with Practice E 180. The withinlaboratory coefficient of variation was found to be 1.1.%
relative at 193 df and the between-laboratory coefficient of variation was 2.5 % relative at 178 df. Based on these coefficients the following criteria should be used for judging the acceptability of results at the 95 % confidence level.
(a) Repeatability--Two results, each the mean of duplicate determinations, obtained by the same operator on different days, should be considered suspect if they differ by more than 2.9 % relative.
(b) Reproducibility--Two results, each the mean of dupli cate determinations, obtained by operators in different laboratories, should be considered suspect if they differ by more than 7.1 % relative.

N' 1--Other substrates that may be suitable are 10-rail (250-jim)
thick polyethylene (7), photographic paper (8), polished steel (9), and juoropolymer coated metal panels.
7, Hazards
7.1 Mercury--Mercury is a toxic metallic liquid. Its vapors are extremely hazardous. Small amounts of spilled tnercury can vaporize sufficiently at room temperature to exceed the TLV of the vapor. Use with adequate ventilation (in a hood) and clean up spills, immediately. Wear gloves tvhen handling mercury. Containers should be kept closed, proplets of mercury can be picked up by using a small glass pipet connected to a suction flask with a rubber hose.
g. Test Specimens
8.1 The test specimens shall be free films having a width that is between V2 and 1 in. (13 and 25 mm). No specimen shall vary by more than 2 % in width along its entire length. The length shall be at least 2 in. (50 mm) longer than the gage length selected for the test.
8.2 Prepare the free films by one of the following proce dures:
8.2.1 Dental Tin Foil Substrate: 8.2.1.1 Apply each material to be tested to a strip of dental tin foil. First, mount the foil on a smooth glass plate on which there may be placed a small pool of high-boiling liquid, which may be useful in holding the foil in close contact with the glass. Spread the foil out to a smooth flat surface by means of a rubber squeegee. Apply a uniform coating of the material on the foil by automatic spray or drawdown procedures given in Test Method D 823,
N' 2--Use a liquid that is known to have little or no effect on the
test coating. In many cases a light mineral oil would be suitable.
8.2.1.2 Dry the applied films at 73.5 3.5F (23 2C) and 50 5 % relative humidity or bake under conditions mutually agreeable to producer and user. Dry film thick nesses must not vary by more than 5 % of the average film thickness. Most films with a thickness of less than 2.0 mils (50 jim) are very difficult to handle.
8.2.1.3 When required for further treatment such as weathering, remount the coated foil on a convenient smooth, flat substrate such as a glass or steel panel. In this case, a high boiling liquid (Note 2) may be used to hold the foil in close contact with the substrate over extended periods of time.
8.2.1.4 Age or expose the coated foil to conditions mutu ally agreed upon. At the end of the specified or agreed upon period, remove the foil-backed film from the glass or metal substrate and cut the specimens to size using the precision specimen cutter.
N' 3--A precision specimen cutter must be used to ensure
nick-free edges on the specimens. Even with this instrument, it is necessary to cut each specimen independently, allowing at least 'U in. (6 mm) of waste between specimens.
8 Teflon FEP 2-mil film thickness (Card No. 03111, Item. #22499) from E. L du Pont de Nemours & Co., Inc., Wilmington, DE 19898, is satisfactory.
9 Dry lubricant (MS-122 Fluorocarbon Release Agent) from Miller-Stephenson Chemical Co., Danbury, CT 06810, is satisfactory.
8.2.1.5 Place the foil-backed specimen film side up on a pool of mercury to remove the foil by amalgamation.
N' 4--Care should be exercised at all times to prevent the
high-boiling liquids used in mounting the foil from coming in contact with the test film as these liquids may soften the film. For instance, the foil should be cleaned before amalgamation since any liquid remaining on the back ofthe foil and the test film will float on the bath of mercury.
8.2.1.6 After amalgamation is completed, pick, up an end of the floating film with tweezers, and carefully brush the unsupported film free of mercury and amalgam with a soft camel hair brush.
8.2.2 FEP Sheet Substrate: 8.2.2.1 Apply each material to be tested to a sheet of FEP. First, cover a smooth, flat, polished glass plate with a sheet of FEP. Coat the sheet uniformly with a dry fluorocarbon lubricant and allow to dry for 24 h at standard conditions. Then apply a uniform coating of the test material on the sheet by automatic spray or drawdown procedures given in Method D 823. 8.2.2.2 Dry the applied films at 73.5 3.5F (23 2C) and 50 5 % relative humidity or bake under conditions mutually agreeable to producer and user. Dry film thick nesses must not vary by more than 5 % of the average film thickness. Most films with a thickness of less than 2.0 mils (50 |im) are very difficult to handle. 8.2.2.3 When required for further treatment such as weathering, remount the coated sheet on a convenient smooth, flat substrate such as a glass or steel panel. 8.2.2.4 Age or expose the coated sheet to conditions mutually agreed upon. At the end of the aging or exposure period, remove the sheet-backed film from the glass or metal substrate, and cut the specimens to size using the precision specimen cutter (see Note 3). Carefully strip the coating film from the sheet substrate.
9. Calibration
9.1 Balance, zero, and calibrate the load weighing and recording system of the tensile tester in accordance with methods specified by the manufacturer.
10. Conditioning
10.1 Unless otherwise agreed upon between the producer and the user, condition the test specimens for at least 24 h at 73.5 3.5T (23 2C) and 50 % relative humidity and test in the same environment.
11. Procedure
11.1 Select a mutually agreed upon gage length in the range of 1 in. (25 mm) to 5 in. (125 mm).
11.2 Prepare 10 test specimens for each material to be evaluated. These specimens should not exhibit any nicks or flaws. Measure the thickness of each specimen to 0.1 mil (2.5 Jim) with a micrometer in accordance with Test Methods D 1005, taking five measurements within the gage length area.
11.3 Set the jaw separation of the tensile tester at the gage length selected. Place the test specimen in the grips of the testing machine, taking care to align the long axis of the specimen1 with an imaginary line joining" the points of attachment of the grips to the machine. Tighten the grips evenly and firmly to the degree necessary to minimize
305

D 2370
slipping of the specimen during test.
N' 5--Mounting is facilitated by the use of air activated jaws.
Line-type jaws will minimize slippage and breakage. The application of pressure-sensitive cloth to the ends ofthe film can improve jaw grip.
11.4 Select a mutually agreed upon rate of elongation (strain rate) that is in the range of 5 to 100 %/min. Set the crosshead speed of the tensile tester to provide this rate for the gage length chosen.
N' 6--A rate of elongation should be selected that is optimum for
testing the types of materials to be evaluated. For relatively brittle films, elongation rates of 5 to 20 % are suggested. For relatively extensible films, elongation rates of 50 to 100 % are suggested, (Refer to Test Methods D 882 for relation of elongation rate to elongation at break).
11.5 Elongate the test specimen until rupture of the film occurs and evaluate the stress-strain curve as follows:
11.5.1 Determine the specimen elongation by measuring the increase in jaw separation from the point of original load application to the point of rupture.
11.5.2 Measure the tensile pull in pounds (kg) required to rupture the film.
11.5.3 If stiffness is desired, determine the tensile pull in pounds (kg) to elongate the film t % from the first point in the stress-strain curve where the slope becomes constant.
11.6 Using the procedures in sections 11.1 through 11.5, run ten test specimens for each material under test
12. Calculations
12.1 For each specimen compute the following: 12.1.1 The elongation E, in percent from the following equation:
where: AL = increase in specimen length to break, and L = initial specimen length (gage length).
12.1.2 The tensile strength, T.S., in pounds per square inch, from the equation:
T.S. = {Pk )!(TW)
where: PK = tensile pull to rupture, lb (kg), T - thickness of test specimen, in. (mm), and W = width of test specimen, in. (mm).
12.1.3 The stiffness (modulus of elasticity), S, from the following equation:
5 = {PE)/{TW)
where: PE = pull in pounds (kg) to elongate the film 1 % from the
first point in the stress-strain curve where the slope remains constant, T = thickness of test specimen, in. (mm), and
W = width of test specimen, in. (mm).
12.2 Examine the uniformity of the tensile strength and elongation results obtained for the ten specimens measured for a material. Choose one of the following procedures f0r discarding spurious values and calculate the mean of the remaining results:
12.2.1 Use the results from those five specimens showing the highest tensile strength in evaluating all three properties discarding those from the remaining five. This is done on the I basis that the expected errors (nicks or flaws in the specimen breaks within thejaw, slippage in thejaw, etc.) would all tend to produce results on the low side.
12.2.2 Discard the values for those specimens where the 1 tensile strength and elongation values are significantly lower than those for most ofthe specimens. Use the test for outliers given in Practice D 3980.
13. Report
13.1 Report the mean values obtained with the test
specimens for:
1J. 1.1 Tensile strength,
13.1.2 Elongation, and
13.1.3 Stiffness (modulus of elasticity), if desired.

14. Precision
14.1 An interlaboratory test ofthis method was conducted
in which three coatings (representing a brittle film, a film
with limited elasticity, and a very elastic film) were tested by
five laboratories. The test was conducted with an lnstron ;
tensile tester operated at two elongation rates (10 and 100%) :
with a specimen gage length of 2 in. (50 mm) and specimen ;
thicknesses of 2.5 to 3.5 mils (65 to 90 pm). The between :
laboratory coefficients of variation were found to be 30 % for [
percent elongation and 18 % for tensile strength. Based on
these coefficients, the following criteria should be used for
judging the acceptability of results at the 95 % confidence i
level:
14.1.1 Reproducibility--Two results for percent elonga- ;
tion obtained by operators in different laboratories should be ;
considered suspect if they differ by more than 118 % of their ;
mean. Two results for tensile strength obtained by operators '
in different laboratories should be suspect if they differ by j
more than 70 % of their mean.

7.3 Add 60 mL of extraction mixture (5.2) and stir well #ith the glass, screw-type stirring rod, preferably using a power stirrer. Wash the rod clean with a stream of extraction fixture into the tube, and reserve the rod. If the glass bottle jS used, mixing may be accomplished by hand, shaking vigorously, or by use of a mechanical shaker.
7.4 Centrifuge at 1000 to 2000 g (Note 2) until the pigment is clearly separated. A faster speed may cause the pigment to pack too hard for future mixing. (See Test Method D 2698.)
N' 2--Calculate the gravity developed by the centrifuge as fol-
lows;
g= 1.118 x 10_s x rX n2
(1)
where: r = rotating radius, mm, and n = rotating speed, r/min.
7.5 Discard the upper layer by decantation. 7.6 Repeat the extraction twice as described in 7.3, 7.4, and 7.5, making certain that the settled pigment is suffi ciently stirred or shaken so that no lumps can be seen sticking to the side of the centrifuge tube or bottle and all pigment can easily be washed from the stirring rod into the
tube. It may be necessary to break up the pigment cake before stirring. The bottle and contents may be mixed by tapping at an angle on a cloth pad on a bench top to break up the pigment cake and then shaking vigorously to complete the pigment dispersion in the extraction mixture.
7.7 Make a fourth extraction using ethyl ether or petro
leum ether following the same precautions noted in 7.6. Decant the upper layer. Drive off the ether by heating (gently at first to avoid spattering) on a steam bath in a hood away from open flames or sparks. The pigment should be broken up by tapping the tube or bottle on a cloth pad on a bench
top. Dry the tube or the bottle at 105 2C for 2 h. 7.8 Cool and weigh the tube (including stirring rod) or
bottle, plus pigment.
8. Calculation
8.1 Calculate the percent of pigment, P, as follows:
P=[{W,~ W2)jS\xm

where:
Wi = weight of the tube (including stirring rod) plus pigment, g,
W% - weight of the tube (including stirring rod), g, and S = weight of paint sample used, g.
N' 3--All pigment obtained using this test method has minute
amounts of vehicle adsorbed on the pigment. However, this will not
significantly affect the precision of this test method.

3. Terminology
3.1 Definition: 3.1.1 overbaking--an exposure of the coating to a moder ately higher temperature or to a longer period of baking, or both, than recommended by the manufacturer of the coating for normal curing. This condition is in contrast to "heat resistance" which is a parameter relating to the service life of a coating.
4. Summary of Practice
4.1 Four panels are prepared and baked at the schedule normally recommended for the coating. Two of the panels are then removed and the remaining two are subjected to an additional overbake in which the time and temperature are mutually agreed upon between the- purchaser and the seller. The sets of panels, after a suitable conditioning interval, are then evaluated for the properties that are compatible with the substrate. Among these are gloss, color, flexibility, adhesion, impact resistance, and resistance to reagents. Note that glass substrates should not be tested for impact, and zinc-coated substrates can influence both flexibility and impact.
5. Significance and Use
5.1 Most coatings are designed for a specific baking time and temperature. For a variety of reasons (line stoppages, rerouting back through ovens, oven overheating, etc.) the prescribed time or temperature, or both, of the bake is often exceeded. This practice has been found to be useful in evaluating the effects of overbakes on coatings.
6. Materials
6.1 Standard Baking-Type Coating mutually agreed upon between the purchaser and the seller.
313
DU P0502 97496
D 2454
7. Hazards
7.1 The flash points of most solvents used in many organic coatings and related products are low enough that adequate ventilation is needed to avoid exceeding 25 % of the lower explosive limits ofthe solvents when test panels are being prepared and baked. As these materials are considered toxic, take care to avoid inhalation of solvent vapor and unnecessary contact of solvent with the skin.
8. Procedure
8.1 Application ofOrganic Coating: 8.1.1 Apply coatings to steel panels prepared in accord ance with Methods D 609. 8.1.2 Apply coatings to zinc-coated surfaces prepared in accordance with Practices D2092, when zinc has been applied by the hot-dip method or by electroplating. 8.1.3 Apply coatings to nonpassivated galvanized steel prepared in accordance with Test Method D 2201, when the zinc is applied by a continuous galvanizing method using an aluminum-bearing zinc. 8.1.4 Apply coatings to aluminum surfaces on all-alu minum materials prepared in accordance with Practices
D 1730. 8.1.5 Apply coatings to hot-dip aluminum coated surfaces
prepared in accordance with Practices D 1731. 8.1.6 In cases where a primer is used in practice under the
topcoat, apply the entire system to the panels. The film thickness of each coat shall be mutually agreed upon between the purchaser and seller, but, in the absence of such agreement, the total thickness shall be 2 0.2 mils (50 5
pm). 8.1.7 In instances where clear coatings are to be tested,
they may be applied to aluminum or white carrara glass, one side of which has been polished to a smooth, high-gloss finish. Other selected substrata previously agreed upon between the purchaser and the seller may also be used. In the absence of a specific agreement between the purchaser and the seller in regard to film thickness, apply the coatings by automatic spray. (Refer to Test Methods D 823, Method A) at a dry film thickness of 2 0.2 mils (50 5 pm). Multiple coats may be used to obtain this film thickness where necessary due to the nature of the coating material (Note 1). Manual spray application or the drawdown method with wire-wound draw bars may be used when automatic equip ment is not available.
N ' 1--Dry film thickness should be measured in accordance with
Test Methods D 1005, V 1186, or D1400, whichever is applicable. The adhesion, flexibility, and color can vary considerably with thickness.
8.2 Baking: 8.2.1 The baking schedule for each coating including primer, topcoat, and primer/topcoat systems shall be mutu ally agreed upon between the purchaser and the seller and shall include the following: 8.2.1.1 Normal Baking Schedule (Time and Temperature) recommended for the development ofoptimum film proper ties, and 8.2.1.2 Overbaking Cycle--This cycle shall be within practical limits in order to simulate conditions that might be encountered in actual production where baking oven or conveyor lines, or both might malfunction temporarily due to mechanical or electrical failure.
8.3 Prepare four panels of each coating or coating system >
and bake them at the schedule normally recommended to
obtain optimum properties. Conduct the baking of these \
panels in a mechanical recirculating air oven set to 2F
( l'C) of the specified baking temperature. At the end of the >
specified time remove two panels from the oven and subject
the remaining two to the overbake cycle by:
8.3.1 A continuation of the normal bake but for a
previously agreed upon time, for example, 50 or 100%
increase in time, or
8.3.2 Resetting the oven temperature to the agreed \
overbake temperature and then continuing the bake for a
specified period of time after the overbake temperature has
been reached, or removing the panels until the overbake !
temperature is reached and then baking them for the agreed
upon time.
'j
N' 2--The conditions described in 8.3.2 are not usually reproduc
ible between laboratories or different ovens because of variations in the
heating characteristics of ovens.
8.3.3 After the sets of panels have been baked according to'the mutually agreed upon baking cycles, place them in a suitable rack and condition for 24 h at 73.5 3.5F (23
2C) and 50 5 % relative humidity (see Test Methods D 1640) prior to testing.
9. Test Methods
9.1 Determine the properties of both sets of panels in accordance with the following ASTM methods:
9.1.1 Gloss--Test Method D 523. 9.1.2 Color--Practice DT'729 (Visual) or Practice E805 (instrumental), or both 9.1.3 Flexibility--Test Method D522 (conical mandrel
and cylindrical mandrel). 9.1.3.1 Heat-aged flexibility values should be determined
in accordance with a baking cycle that is in agreement between the purchaser and the seller.
9.1.4 Adhesion--Test Methods D 2197 (mechanical) or D 3359 (tape), or both,
9.1.5 Impact Resistance--Test Method D 2794.5 9.1.6 Hardness--Test Method D 3363 (pencil test). 9.1.7 Exposure to Reagents--If this test is desired, the choice ofmaterials to which the coating is to be exposed shall be governed by the ultimate use of the coating and shall be agreed upon between the purchaser and the seller. The general procedure to be followed in this test is given in Test Method D'1308 or Practice D1540.

evaluated under one or both of two test methods depending on the intended usage.
3.1.1 Test Method A, Interior Service Coatings--Coated panels are heated for 24 h in a muffle furnace at a temperature agreed upon between the purchaser and the seller. One panel is plunged into water and the other cooled and then subjected to a bend test.
3.1.2 Test Method B, Exterior Service Coatings--Coated panels are subjected to temperatures that increase in steps from 400 to 800F (205 to 425C). One panel is subjected to salt spray for 24 h, and one is exposed outdoors for 12 months.
3.2 When tests are completed, the panels are examined for evidence of film degradation including rust formation, blis tering, loss of adhesion, dulling, and chalking.
4. Significance and Use
4.1 Some coating systems are developed for use over steel that is exposed to high temperatures during service life. This method provides an accelerated means of determining the performance of these coating systems. Testing of coatings designed for interior service and of coatings designed for exterior (weather-exposed) service is included.
5. Apparatus
5.1 Automatic spray equipment as described in Test Methods D 823 (Method A) or any other suitable method that will give the required uniformity of film and film thickness.
5.2 Muffle furnace capable of maintaining the tempera tures described in 7.2 and 7.3.
5.2.1 Precaution: Due to the high temperatures involved in operating the muffle furnace, extreme caution should be used.
5.3 Salt spray apparatus as described in Method B 117.
6. Panel Preparation
6.1 Type--Panel dimensions shall be established by prior i agreement between the purchaser and the seller. Use panels of lA in. (6.4 mm) hot-rolled steel conforming to Specifica tion A 36/A 36M or Specification A 283/A 283M, or when appropriate, Specification A285/A285M for the water quench test in Test Method A and for all tests under Test Method B. For the bend test in Test Method A, the panels must be thin and soft enough to be bent as described in Test Methods D 552.
6.2 Cleaning--Clean the panels for both test methods iojl accordance with Methods D609, Methods B or D. Then, using a fine silica sand (graded to pass through a No. 4G (425-pm) sieve), blast the panels for Method B to "wbiter metal (removing all mill scale and rust) so that the panels'

comply with grade A SP-5 of Standard D 2200. Other blast media and blast methods are acceptable if agreed upon between the buyer and the seller. Blast-cleaned panels cannot be subjected to the bend test because they are too thick to bend.
6.3 Coatings Applications--Apply the coatings by auto matic spray, Method A of Test Methods D 823, or by any other suitable method that will assure the required unifor mity of film thickness. The number of coats, technique, and cycle for drying between coats of multicoat systems, limits of dry film thickness, and drying time before exposure shall be established by prior agreement between the purchaser and the seller. Determine dry film thickness in accordance with Test Methods D 1186. Allow coatings that air dry at ambient temperature to dry a 168 h at a temperature of 75 5T (24 2.5C) prior to exposing to test conditions. Bake coatings that require heat conversion in accordance with the recom mendation of the supplier.
7. Procedure
7.1 Sampling--When panels have been coated at another location, select at random from different packages two specimens for each method of each type of coating under investigation.
7.2 Test Method A: 7.2.1 Place one panel each of the two types described in 6.1 and 6.2 coated with each paint under test in a muffle furnace maintained at the test temperature mutually agreed upon between the purchaser and the seller, and allow to remain for 24 h. At the end of this time plunge one of the panels immediately into water maintained at 70 5F (21 2.5C). After removing from the water, examine the coating film for evidence of film failure including dulling, blistering, cracking, and loss of adhesion. Allow the second panel to cool at a room temperature of 75 5F (24 2.5C) for 1 h, then rapidly bend double over a '/2-in. (12.7-mm) diameter steel mandrel with coated side uppermost in accordance with Test Methods D 522, Method B. Examine this panel for evidence of film degradation such as cracking and loss of adhesion. 7.3 Test Method B: 7.3.1 Expose duplicate coated panels finished with the materials under test to the elevated temperature test schedule mutually agreed upon between the purchaser and the seller. In the absence of such a specified schedule use the following: 7.3.2 Place the panels in a muffle furnace maintained at 400F (205C) for 8 h, then increase the temperature to 500F (260C) for 16 h. Increase the temperature in 100F (55C) increments, alternating the time periods indicated, to the final temperature maximum previously agreed to be tween the purchaser and the seller. Thus the schedule would be:
400F (205C) for 8 h 500"F (260C) for 16 h 600F (315C) for 8 h 700F (370C) for 16 h 800"F (425'C) for 8 h
N' --Many high temperature paints depend upon service condi
tions to provide the extreme heat required to cure or sinter their films. If these paints are never exposed to the extreme heat, they may be found to be unsuitable. Consequently, it is good practice to make observations also at temperatures less than the expected service temperatures.
7.3.3 Remove the test panels and make a visual inspection following exposure at each temperature level for evidence of failure, including peeling, cracking, blistering, abnormal discoloration, or loss of adhesion, using ASTM standards where possible. Disregard such failures up to 'A in. (6.4 mm) in from the edges of the test panels.
7.3.4 At the end of the complete exposure, remove the panels from the oven or muffle furnace and allow to air cool at ambient temperature for a minimum period of 1 h. As described in 7.3.3, inspect for evidence of failure due to the high temperature exposure.
7.3.5 If both panels of each pair pass the heat test satisfactorily, use them, respectively, for salt spray (fog) testing and exterior exposure testing.
7.3.5.1 Place one panel of each pair in a salt spray cabinet operated in accordance with the requirements of Method B 117, for a period of 24 h. At the conclusion of the exposure period, examine each panel for rusting or any evidence of corrosive attack.
7.3.5.2 Expose the second panel of each pair on an insulated-type rack, as described in Practice G 7, or as agreed upon between the purchaser and seller, for a period of 12 months. Make a visual inspection after 6 months and after termination of the exposure. The site to conduct the test and the angle of the exposure rack should be agreed upon between the purchaser and the seller and should relate to the end-use application of the coating.
8. Report
8.1 Report the following information: 8.1.1 Description of substrates, substrate preparation, and application conditions used. 8.1.2 Air drying versus baking schedule used. 8.1.3 Details of outdoor exposure when applicable, in cluding: 8.1.3.1 Exposure site, type (insulated rack, black box, open rack, etc.) and angle of exposure, 8.1.3.2 Date of exposure start, 8.1.3.3 Radiation data in terms of kilojoule per square metre or langleys during exposure period, and 8.1.4 Any defects or changes as described under Section 7.
9. Precision
9.1 Four operators in four laboratories tested six materials covering a range of heat-resistant properties and were able to rank products in order of their heat-resisting qualities. Since rankings were of a qualitative nature, no mathematical statement of reproducibility was established.

Standard Test Method for Scrub Resistance of interior Latex Fiat Wall Paints1
This standard is issued under the fixed designation D 2486; the number immediately following the designation radicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (s) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers an accelerated procedure for determining the resistance of latex flat wall paints to erosion caused by scrubbing,
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.
2. Referenced Documents
2.1 ASTM Standards: D4213 Test Method for Wet Abrasion Resistance of
Interior Paints2
3. Summary of Test Method
3.1 The test paint is applied to a black plastic panel. After aging, the coated panel is placed, over a '/2-in. by 10-mil (12.7 by 0.25-mm) shim and held in place on a glass plate in a washability machine by means of a gasketed frame. It is then scrubbed with a nylon bristle brush and an abrasive scrub medium until failure occurs over the shim.
4. Significance and Use
4.1 Interior wall paints often become soiled especially near doorways, windows, and in work and play areas. This test method covers determination of the relative resistance of different wall paints to erosion when repeatedly scrubbed to remove the stains during the life of the paint.
4.2 Results developed by use of this test method do not necessarily represent the scrub resistance of aged paint films.
4.3 This test method measures scrub resistance by the traditional scrub-to-failure concept. Test Method D 4213 is a more precise method that measures essentially the same property by a weight-loss technique and reports it as a volumetric film erosion rate. Test Method D 2486 is main tained as an ASTM standard along with the newer Test Method D4213 because it has served the paint industry usefully for many years, its techniques are familiar, and its results are meaningful. To discard it as a standard would be to minimize a great deal of significant past experience.
' This test method is under the jurisdiction of ASTM Committee D-l on Paint and Related Coatings and Materials and is the direct responsibility of Subcom mittee DO 1.42 on Architectural Finishes.

28 % ammonium hydroxide while mixing, and continue mixing until solution turns clear. In the order given, add the other ingredients separately, employing mechanical stirring. Be sure that each item is uniformly dispersed before adding the next one. The addition of the silica should take about 5 min to ensure uniform dispersion. Finally, add the preserva tive and adjust the pH with glacial acetic acid.
7. Preparation of Apparatus
7.1 Washability Machine--The washability machine should be leveled before use and operated at 37 1 counts per minute. Before each test check the tightness ofthe motor belt or chain drive, alignment of the pulleys and cables in both horizontal and vertical planes, and tautness ofthe cable.
7.2 Brush--The bristles, if new, must be leveled before use to permit uniform wear on the paint surface. Leveling is accomplished by running the brush over 100 or 120-mesh aluminum oxide close grain sandpaper or emery cloth attached lengthwise on the glass plate in the washing machine. The total number of cycles required will vary from 1000 to 5000. Additional weight, up to 454 g, may be used to expedite the procedure. Change the sandpaper or emery cloth if it becomes clogged. Tape down the edges if any tearing is observed. Replace brush when bristles have worn to extend less than 5/s in. (16 mm) from block.
7.3 Brush Holder--Screws on the brush holder shall be removed and not used. Instead, insert a [/s-in. (3.2-mm) thick rubber mat in the holder above the brush block. When in operation, this mat allows the brush to ride evenly on the paint surface without tilting (Fig. 1). The brush must fit loosely in the holder.
8. Procedure
8.1 Clean the top of the glass plate (or preferably suction plate) and both sides of the black plastic panel to be sure they are free of specks. Place the black panel on the plate and tape one end to the plate. Smooth the panel along the plate by rubbing with flannel, creating static electricity which im proves adhesion to the plate.
8.2 Stir the test paint thoroughly and strain to remove all skins and particles. Draw down the paint on the panel using the 7.0-mil (0.18-mm) side of the film caster, starting from the taped end of the panel. The time for application should be fairly slow--3 to 4 s from end to end--to prevent formation of pinholes or holidays in the film. Air dry in a horizontal position for 7 days in an open room kept at 73.5 3.5F (23 2C) and 50 5 % relative humidity.
8.3 Clean the plate and set it in the pan of the washability machine. Be sure that the shim is smooth and free of burrs and placed across the center of the plate. Wipe the test panel carefully and place it on top of the shimmed plate with the painted side up. Be sure that there are no defects in the film above the shim and that the test area is level. Prewet the gasket of the frame and wipe it dry before use. Place the frame over one half of the drawdown, being sure that the entire gasket is on the painted surface. (The other halfcan be used for a second test if desired.) Clamp the gasket in place. The clamps should be tight enough to ensure close contact, but not tight enough to cause warping of the panei.
8.4 Soak the brush in a 1 % solution of detergent6
FIG. 1 Accessory Apparatus for Scrub Test
overnight. Remove the brush and shake it vigorously to remove any excess. Mount the brush in the holder being sure that the mat is in place above the brush block and that the brush is always in the same position. (Mark both brush and holder beforehand.) Stir the scrub medium and spread 10 g evenly on the brush bristles. Place the brush at one end ofthe path and attach the guide cables. Wet the panel with 5 mL of reagent water in the path of the brush.
8.5 Set the cycle counter at zero. Start the test. After each 400 cycles before failure remove the brush (do not rinse); add 10 g of stirred scrub medium; replace the brush, being sure that brush and holder are in the same position with relation to each other and in the machine. Place 5 mL of water on the path before continuing.
8.6 Record the number of cycles to remove the paint film fully in one continuous line across the '/2-in. (12.7-mm). width of the shim. Stop the machine and wipe off the area to determine the end point
8.7 Make three drawdowns of each specimen. Test two and average them if they are within 25 % repeatability. If they are not, test a third and average the three, unless one of the results is obviously discrepant, in which case it should be discarded. According to the 90 % confidence limits specified herein, the running of a third test will be required, on the average, only one out of ten times for normal results.

5.3.7 Following the incubation period, use the broth f culture prepared in 5.3.6 to proceed as described in Section'
6.
5. Procedure
6.1 Preparation ofSpoiled Paint: 6.1.1 Transfer the well-shaken broth culture prepared in 5.3.6 to the 1-qt (945-mL) sample of paint (see 4.3). Shake the inoculated paint well before proceeding. 6.1.2 Incubate the paint at 27 to 28C for 1 week. 6.1.3 To determine whether or not the paint contains bacteria at the end of the incubation period, use a sterile cotton swab to transfer a specimen of paint to the surface of a tryptone-glucose agar slant. Incubate agar slant at 27 to 28C for 72 h. If colonies ofPseudomonas aeruginosa appear on the agar surface, paint is satisfactory for use as spoiled paint in 6.4.1. If colonial growth ofPseudomonas aeruginosa does not appear on the surface, repeat 6.1.1 and 6.1.2. 6.2 Preliminary Examination ofPaint Under Test: 6.2.1 Examine the can for evidence of swelling. If the can is swollen, exercise caution in removing the lid. 6.2.2 Remove the lid and smell the contents of the can. Deterioration of paint by microorganisms is often character ized by distinct odors. Such odors may be either putrefactive or fermentative. 6.2.3 Observe the contents of the can for the presence of stringy structures characteristic of the presence of certain microorganisms. 6.2.4 Observe the contents for noticeable losses in vis cosity. This physical change frequently occurs as the result of microbiological deterioration. 6.3 Determination ofPresence or Absence ofLiving Micro
organisms in Paint Under Test:
6.3; 1 Soak a sterile cotton swab in the paint under test. Remove excess paint by pressing gently against inside of container.
6.3.2 Transfer the test paint to the surface of a tryptoneglucose agar slant by pressing the swab gently on the agar surface.
6.3.3 In order to obtain duplicate agar slants, repeat 6.3.1 and 6.3.2.
6.3.4 Incubate the inoculated agar slants at 27 to 28C for a minimum of 1 week.
6.3.5 If colonial growth of bacteria is observed on the agar surface at the end of the incubation period, the test is complete and may be reported in accordance with Section 7.
6.3.6 If colonial growth of bacteria is not observed on the agar surface at the end ofthe incubation period, continue the test as described in 6.4.
6.4 Challenging Test Paint by Inoculation: 6.4.1 To 100 g of the paint under test, add 1 g of pant spoiled in 7.1. 6.4.2 Incubate the paint for 6 weeks at 27 to 28C. 6.4.3 At the end of24,48, 72 h and 1 week of incubation and once each succeeding week throughout the incubation period, soak a sterile cotton swab in the paint. Remove excess paint by pressing against the side of the container and transfer the paint to the surface of a tryptone-glucose agar slant. 6.4.4 Incubate the agar slant at 27 to 28C for 1 week and observe the presence or absence of colonial growth of bacteria. 6.4.5 At the end of 6 weeks add an additional 1 g of paint spoiled in 6.1. Incubate for 2 weeks at 27 to 28C and repeat 6.4.3 and 6.4.4.
7. Report
7.1 Report the following information: 7.1.1 Results of observations noted under 6.2. 7.1.2 Presence or absence of living microorganisms in the paint as received, and after it has been inoculated (or reinoculated) with a sample of spoiled paint. 7.1.3 If living microorganisms are found in the paint as received, or after inoculation (or reinoculation), the paint shall be reported as "not resistant in the container to attack by microorganisms." 7.1.4 If living organisms are not found, the paint shall be reported as "resistant in the container to attack by microor ganisms."
8. Precision and Bias
8.1 No statement is made about either the precision or bias of this test method for measuring the resistance of emulsion paints in the container to attack by microorgan isms, since the result merely states observations of the paint under test and presence or absence of living microorganisms in the paint as received or after inoculation.

coating which would not be lifted by the clear topcoat. (A baking enamel with the composition of 30% melamine formaldehyde resin and 70 % of the phthalie anhydride/coconut alkyd resin with 3 Ib/gal (1.36 kg/L) of titanium dioxide, per. gallon has been found satisfactory.) (3) The substrate intended for use with the clear coating. The light stability of the substrate may be determined by including an extra test panel without a clear topcoat.
6.2 Prepare specimens of the test materials by applying the coatings on the test panels to a dry film thickness of 2 0.2 mil (50 5 pm).
6.3 Prepare a reference specimen, representing a material . of known, performance in this test, with each set of test specimens.
6.4 Record the panel preparation details: method of coating application, baking conditions, film thickness, etc. These details will be established by mutual agreement between purchaser and seller in accordance with the type of product and its intended use.
3. Summary of Method
3.1 The effect of sunlight on discoloration of clear coat ings is determined by exposing under glass, coated panels masked at one end, to natural sunlight for a specified time. At the end of the exposure, the mask is removed and the panels evaluated for degree of discoloration.
7. Conditioning
7.1 Unless otherwise specified, condition the coated panels at 73.5 3.5F (23 2C) and 50 5 % relative humidity for 48 h if baked, or 7 days if air dried.
4. Significance and Use 4.1 Color change, particularly yellowing, is not generally
acceptable to users of coatings when it is readily noticeable. In designing clear coating systems for interior use on various substrates, it is of interest to know how well the clear coats will resist color change caused by ambient light. This test method permits the evaluation of the effect of natural indoor light on the color stability of clear coatings.
5. Apparatus
5.1 Exposure Cabinet as described in Practice G 24.
6. Test Specimens
6.1 For each clear coating under test, use one test panel approximately 3 by 5 in. (75 by 125 mm) of white carrara glass or other specified substrate material.
N' 1--Other materials that may be considered for this purpose
include: (/) White ceramic tile. (2) A white pigmented, light-stable
8. Procedure
8.1 Prior to exposure, mask one-half of each test panel with aluminum foil to exclude sunlight from the other half of the coating.
N' 2--The tape used to attach the mask to the panel should not
extend over the edge of the mask but should extend beyond the ends of the mask and stick to the rear of the panel, thereby holding the mask in position. This will prevent contact between the tape and the finish and eliminate the possibility of staining from the tape.
8.2 Mount the test specimens in the glass-covered expo sure cabinet continuously 24 h a day for the specified period of exposure. It is recommended this period should be approximately 5 weeks, since longer periods of exposure do not significantly change the results.
N' 3--In cooperative tests, exposure of nitrocellulose lacquers,
cellulose acetate butyrate lacquer, and low-bake alkyd enamel for 22 weeks did not show significantly greater discoloration than after exposure for 5 weeks.

10. Color Changes Not Caused by Light'
10.1 In many cases atmospheric conditions (temperature, humidity, reactive gases) may produce significant color changes even without the presence of light. An indication as to whether or not side effects are operating may be obtained by retaining unexposed a duplicate set of specimens in the laboratory. A difference in color between the unexposed specimens and the covered portion ofthe exposed specimens indicates that the material has been affected by some agent
other than light. 10.2 Further clarification regarding atmospheric effects
may be obtained by simultaneously exposing a duplicate set of test specimens in another cabinet ofthe same type used in the light exposures but with the glass covered with an opaque material so that the light is excluded.

12. Precision
12.1 Because of the many variations in visual rating 0f |
discoloration, meaningful estimates of precision cannot beA given. In cooperative tests, however, fairly good agreementf
was obtained by the various cooperators in the visual rating i
of the test panels.

1 Annual Book ofASTM Standards, Vo! 06.03. 3 Annual Book cfASTM Standards, Vol 06.01. * Annual Book cfASTM Standards, Vol 14.01.
5. Significance and Use
5.1 The ability to qualitatively identify paint vehicles is useful for characterizing unknown or competitive coatings, for complaint investigations, and for in-process control.
6. Apparatus
6.1 Spectrophotometer--A recording double-beam in frared spectrophotometer with a wavelength range from at least 2.5 to 15 pm and a spectral resolution of at least 0.04 pm over that range. See Practice E 275.
6.2 Demountable Cell Mount with NaCl window. 6.3 Vacuum Drying Oven thermostatically controlled to operate at 60 2C. A water aspirator vacuum source is satisfactory. 6.4 Oven, Gravity or Forced Draft, capable of maintaining temperature from. 105 to 1 ICC.
7. Procedure
7.1 Place the vehicle, separated from the paint in accord ance with Method D 2372, on a NaCl window and spread to form a uniform film. The thickness of the film should be such that when the infrared spectrum is recorded the transmittance of the strongest band falls between 5 and 15 % (Note). Dry the film in an oven at 105 to 110*C for 15 min and cool in a desiccator. Inspect the film visually for defects such as bubbles, wrinkles, contamination, etc. If defects are present, cast another film. If easily oxidizable substances are present such as tung, oiticica, or linseed oils, the film should be dried at 60 25C in a vacuum oven for 1 h. If solvents of low volatility such as cyclohexanone or isophorone are present, the film may need to be dried for several hours in a 60C vacuum oven.
N' --Numerous procedures and variations may be used to obtain a
film on which to prepare a suitable spectrum. These include liquid mounting between two NaCl plates, transmission through free films, and reflectance from highly polished surfaces.
7.2 Immediately record the infrared spectrum from 2.5 to 15 pm so that a spectral resolution of 0.04 pm is maintained throughout that range (methods for achieving this resolution will vary according to the directions of the manufacturer of the instrument used).
7.3 Compare the spectrum obtained with reference spectra prepared from nonvolatile vehicles of known compo sition (see Annex Al) or consult other published spectra available in the literature (Annex A3). Interpret the spectrum on the basis of available information, recognizing certain limitations- of infrared spectroscopy, and qualifying the interpretation accordingly (Annex A2).

The infrared spectra of vehicles recovered from whole paint are presented in Annex Al. The aim of this compilation is to aid those using Test Method D 2621 in the practical interpretation of.the spectra they obtain.
The spectra are compiled with one representative spectrum of each vehicle presented in both a prism and a grating format. In the discussion of the spectra, the general assignment refers to the first spectrum. The subsequent spectra discussion will include only- those bands which aid in the
identification of the particular modifications being illustrated. In addition, some practical
information is provided where it is believed to be helpful to the analyst. In general^ previously noted band assignments are not repeated.
The data compiled here were obtained from spectra , prepared on very carefully calibrated instruments. In comparing them to spectra prepared in any given laboratory, it is expected that the wavelength values of absorptiqn bands may differ slightly depending upon the calibration of the instrument used.
GROUP I-ALKYDS
A2.1 Spectrum 1: Ortho-Phthalic Alkyd, Medium Oil
Length
A2.1.1 2.9-\im Region (3448 cm"1)--the 2.9-pm band in
alkyds is due to the O--H stretching vibration. This is
usually attributed to the unesterified hydroxyl OH on the
polyhydric alcohol used in manufacturing the alkyd. This
absorption is known to increase on drying of unsaturated oil
modified alkyds due to oxidation of the double bonds. This
absorption band can be used to determine the hydroxyl
number of alkyds.
A2.1.2 3.3 to 3.6-\im Region (3030 to 2778cm~1)--The
bands in this area are all due to aromatic and aliphatic G--H
stretching vibrations.
/
A2.1.3 5 to 6-\un Region (2000' to 1667
The1
5.8-pm band in alkyds is due to the combined 0=0 stretch
of the phthalate and fatty acid esters. Unreacted phthalic
. anhydride, if present, may be detected by the appearanceofa
sharp absorption band at approximately 5.6 pm (1786
cm"1). Free carboxyl groups (due to unreacted fatty acid or
incompletely reacted phthalic acid) may often be detected by
the appearance of a shoulder on the high wavelength (low
frequency) side of the ester carbonyl band...
A2.1.4 6.2 to 6.4-\im Region (1613 to 1563 cm~Ij--The
doublet appearing in this region of the spectrum is due to
vibrations associated with the double bonds in an aromatic
ring. The band shape and position of this doublet is
characteristic of non-oil modified, ophthalic alkyds.
A2.1.5 6.8 to 6.9-\un Region (1470 to 1449 cm"1)--This
absorption is produced by C--H bending vibrations , of
methylene (scissoring deformation) and methyl (asymmet-
rical deformation) groups, in the alkyd. The: intensity of this.'

^etching vibrations of the phthalate ester. These absorp tions are most strongly influenced by the acid portion of the
ggter rather than the alcoholic portion. A2.1.8 13.5 and 14.2-p.m Regions (741 and 704 cm~`)--
fbese two bands are due to out-of-plane bending vibrations 0f ring hydrogens of aromatic compounds having four adjacent hydrogens (orthodisubstitution).
A2.1.9 Comments: A2.1.9.1 Note that in oil-modified alkyds, the intensity of the absorption at 8.6 pm (1163 cm-1) is indicative of the amount of oil modification or oil length of the alkyd. In
unmodified alkyds, this band may be little more than a side shoulder on the 8.9-pm (1124-cm-1) C--O--C absorption. The correlation to oil length is only a very general one in that within a given group of alkyds one may say a sample is a "short," "medium," or "long" oil type.
A2.1.9.2 Alkyd spectra generally reveal little or no infor mation concerning the type of combined oil or polyol present.
A2.1.9.3 Identification of polyol and unsaponifiables may usually be accomplished by infrared examination of saponir fication fractions. Identification of the oil acids used usually requires gas chromatographic analysis of the methylated fatty acids recovered by saponification. (For saponification proce dures see Test Methods D 1467 and D 1962.)
A2.2 Spectrum 2: Ortho-Phthalic Alkyd, Long Oil Length
A2.2.1 8.6 pm (1163 cm-1); fatty acid ester C--O--C A2.2.2 Comments--Note the difference in the 8.6-pm (1163-cm-1) peak compared to Spectrum 1, due to increased oil length.
A23 Spectrum 3: Ortho-Phthalic Alkyd, Tung Oil Modified
A2.3.1 10.12 jun (988 cm-1); --C=C--C=C--G=C-- Conjugated triene unsaturatiom
A2.3.2 Comments--Note the difference in band shapes in the 10 to 10.4-|um region (1000 to 962 cm-1) compared to Spectra 1 and 2. Absorption due to conjugated unsaturation (in such oil types as tung, oiticica, dehydrated castor, and conjugated safflower) occurs here. Oil types used for alkyds l and 2 contain only isolated double honds.
A2.4 Spectrum 4: Ortho-Isophthalic Alkyd

A2.4.S Comments--The spectrum of this alkyd is typical
ofan isophthalic alkyd. The major band that identifies this as
an isophthalate is the 13.7-pm (730:cm-1) band. The pres
ence of orthophthalic alkyd can be suspected by comparison
to a straight isophthalic alkyd spectrum (see following) and
noting the influence of the ortho-phthalate at 7.9 pm (1266
cm-1), 9.0 pm (1111 cm-1), 9.4 pm (1064 cm-1), and at 14.2
Hm (704 cm-1).

A2.5 Spectrum 5: Ortho-Phthalic Alkyd, Benzoic Add Modified
A2.5.1 14.0 to 14.1 pm (714 to 709 cm-1); aromatic ring vibration where ring contains five adjacent hydrogens. Posi
tion is characteristic of benzoate esters.
A2.5.2 Comments--The band at approximately 14.0 pm (714 cm-1) is the identifying peak for this modification. Because of the o-disubstitution peak at 14.3 pm (699 cm-1) present in o-phthalates, it is difficult to observe this band when the benzoic acid modification drops below 3 %.

A2.6.4 11.7 pm (855 cm-1) aromatic ring substitution patterns
A2.6.5 12.9 pm (775 cm-1) aromatic ring substitution patterns
A2.6.6 Comments--The characteristic bands for the iden tification of the paratertiary butyl benzoic acid modification are the ll.7-pm (855-cm-1) and the 12.9-pm (775-cm-1) bands. The other absorption bands, although sharp and distinctive, can tend to be lost in the background of the spectrum when the modification drops below 2 to 3 %.
A2.7 Spectrum 7: Ortho-Phthalic Alkyd, Tall Oil, Rosin Modified
A2.7.1 12.3 pm (813 cm-1) abietic acid ring vibration A2.7.2 Comments--The curve shows only a very slight depression at 12.3 pm (183 cm-1). In general, the band is never very intense and1, if suspected, the presence of rosin is readily confirmed by a Lieberman-Storch spot test. Note also the obscured nature of the 6.3 to 6.5-pm (1587 to 1538cm-1) region. This is most likely due to the salt or "soap" formation with the adds present in the system and the pigment used.

tive, especially the 14.4-pm (694-cm-1) area. It is always best
to consider, the positions of the 3 or 4 absorptions in the far

consisting of a 16-mm objective and a 10-power filar micrometer eyepiece, resulting in a magnification of approx imately 100 diameters, has been found satisfactory. Other combinations of objectives and eyepieces and other magnifi cations may also be suitable, although magnifications above 200 diameters may result in distortion of the viewed cross section.
3.2 Toolfor Extracting Test Specimens--The tool may be similar in design to an ordinary cork borer, except that it shall be made of thicker walled tubing, hard enough to hold a keen cutting edge, and be fitted with a head suitable for pounding with a hammer (Fig. 1). A leather punch has been found satisfactory for this use. The tool shall make a circular cut approximately lh in. (12.7 mm) in diameter and Vt in. (3.2 mm) deep through the coating and into the substrate. A sidewise movement of the punch while firmly embedded in the substrate will dislodge the specimen and allow its

1 This test method is presently under study for revision or replacement with an improved microscopical film thickness method.
5. Procedure
5.1 Prepare disks for microscopical examination and meas urement by either Method A or Method B. Either method of preparation will expose a cross section of coating and sub strate, including the extremes in film thickness resulting from variations in the wood surface or method ofapplication.
5.2 Method A, Cross Sectioning with Razor Blade--With a sharp razor blade carefully slice away parallel to the coated surface the substrate adhering to the coating until the disk is approximately Vie in. (1.6 mm) thick. Place the disk coated face down on a smooth, hard surface and cut in half by means of a slicing stroke with a fresh razor blade (Fig. 2). Cut in a direction perpendicular to the grain of the wood substrate and at right angles to the coated surface.
5.3 Method B, Cross Sectioning with Microtome: 5.3.1 With a sharp razor blade carefully slice away parallel to the coated surface the substrate adhering to the coating until tiie disk is approximately Vie in. (1.6 mm) thick. 5.3.2 Embed the thinned disk in molten paraffin3 which is

allowed to harden in a small mold to form a block which surrounds the disk on all sides. (The disk may also be dipped successively in the molten paraffin until a reasonably heavy deposit of wax is obtained.)
5.3.3 Trim the paraffin block with razor blade until the sides are parallel to the woodcoating surface.
5.3.4 Mount the trimmed block in a sliding-knife hand microtome4 in such a manner that the embedded disk is vertical with its cross-sectional edge facing and perpendicular to the oncoming knife edge. Cut perpendicular to the grain or to the machine direction of the specimen. The block should be firmly clamped between the jaws ofthe microtome chuck so that approximately one third of the diameter of the embedded disk protrudes.
5.3.5 Make successive cuts with a single sliding movement of the knife, raising the block by small increments after each cut. Continue sectioning until the clamped paraffin block protrudes no more than lAe in. (1.6 mm) above the jaws of the microtome chuck and the embedded disk is sectioned to approximately one half its diameter.
5.3.6 Examine the exposed cross section of the embedded disk with a hand lens to ascertain that a smooth cut has been obtained. If not, resume sectioning until this is accom plished.
Do not measure within V32 in. (0.8 mm) of the edges of the disk, nof in areas where obvious deformation of the coating or substrate has occurred.
7. Report
7.1 Report the average film thickness computed from the ten random measurements as well as the maximum and minimum thicknesses measured to the nearest 0.1 mil (2.5 pm).
7.2 If a more extensive sampling procedure is employed, the report shall show the number of disks examined and the number of measurements per disk, in addition to the maximum, minimum, and average film thickness computed from all measurements.
8. Precision
8.1 Opaque Coatings: 8.1.1 Test Method A--On the basis of an interlaboratory test of this method in which operators in six laboratories tested 12 materials covering a wide range in film thickness, the within-laboratory standard deviation was found to be 0.26 mils with 72 degrees of freedom, and the betweenlaboratory standard deviation was found to be 1.03 mils with 60 degrees of freedom. Based on these standard deviations, the following criteria should be used for judging the accept ability of results at the 95% confidence level: 8.1.2 Repeatability--Two results obtained by the same operator should be considered suspect if they differ by more than 0.7 mils. 8.1.3 Reproducibility--Two results, each the mean of duplicate measurements, obtained by operators in different laboratories should be considered suspect if they differ by more than 3 mils. 8.1.4 Test Method B--On the basis of an interlaborary test of this method in which operators in three laboratories tested 12 materials covering a wide range in film thickness, the within-laboratory standard deviation was found to be 0.28 mils with 36 degrees of freedom and the betweenlaboratory standard deviation was found to be 0.66 mils with 24 degrees of freedom. Based on these standards deviations, the following criteria should be used for judging the accept ability of results at the 95% confidence level. 8.1.5 Repeatability--Two results obtained by the same operator should be considered suspect if they differ by more than 0.8 mils.
6. Microscopical Measurement
6.1 Mount the cross-sectional disk for microscopical ex amination by carefully mounting in parallel clamps, mod eling clay, or in clean sand held in a small container such as a petri dish (Fig. 3). Examine the edge-on view of the specimen by oblique overstage illumination. A focusable microscope lamp and a rotatable microscope stage are recommended for obtaining optimum viewing conditions.
6.2 Determine thickness of the coating above the sub strate at ten randomly selected points on the cross section.

Standard Test Method for Volume Nonvolatile Matter in Clear or Pigmented Coatings1
This standard is issued under the fixed designation D 2697; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapprovai. A superscript epsilon () indicates an editorial change since the last revision or reapproval.
el N' --Keywords were added editorially in January 1991.
1, Scope 1.1 This test method is believed to be applicable to the
determination of the volume of nonvolatile matter of a variety of coatings. An interlaboratory study to establish the precision of this test method included a water-reducible ^terior latex paint and three automotive coatings that included a solvent-reducible primer surfacer, water reducible primer surfacer, water reducible enamel topcoat, and acrylic dispersion lacquer topcoat. Earlier collaborative studies in cluded a gloss enamel, a flat wall paint, a gloss house enamel, an industrial baking enamel, an interior latex paint, and an exterior latex paint.
1.2 This standard does not purport to address the safety problems associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

3, Summary of Test Method
3.1 The weight and volume of a, stainless steel disk are determined. After the disk is coated with the material being tested, the weight and volume of the disk plus dried coating is determined by weighing in air and then by weighing in a liquid of known density, the volume being equal to the quotient of the weight loss of the coated disk (due to the Archimedes buoyancy effect) divided by the density of the liquid displaced. The liquid may be water, organic liquid such as low-solvency mineral spirits or kerosine, or with special modifications not covered specifically in this method, mercury. The choice of liquid depends upon the nature of the coating tested.
1 This test method is under the jurisdiction of ASTM Committee D-1 on Paint wd Related Coatings and Materials and is the direct responsibility of Subcomoittee DO 1.21 on Chemical Analysis of Paints and Paint Materials.

N' 1--Distilled water is suitable for most paints. Exceptions are coatings that contain ingredients that are readily leached out of the dry film by the water and low-gloss coatings, the surface of which is poorly wet by water even with surfactant added. (Note 2) Low-solvency hydrocarbon solvent (KB below 36) is also practical for most paints and is preferred by some workers.3 It is considered to be particularly good for paint films not readily wet by water. Analogously, organic solvents must not be used if the coating to be tested contains ingredients that will be dissolved readily by the solvent Lacquers containing monomeric plasticizers would be examples where hydrocarbon solvents should definitely not be used. Coatings formulated much above the CPVC present a special problem, where mercury might be the desired "sus pending" liquid (Note 3), and for solvent-reducible paints hydrocarbon solvent might be considered the poorest (unless it is the objective to obtain values closer to "theoretical" spaces between pigment particles not filled with binder, becoming partially filled with solvent during the test).
Note 2--Concentration of surfactant must be kept very low or literature values for the density of the water cannot be used.
Note 3--Details of the mercury displacement techniques can be found in the literature.4
3.2 From the measured weights and volumes of the disk before and after coating, the weight and volume of the dried coating film are calculated. Based on the density of the liquid coating and the weight percent nonvolatile matter, the volume of the liquid coating deposited on the coated disk is calculated. The volume of the dried coating divided by the volume of liquid coating, multiplied by 100, provides the volume percent nonvolatile matter in the total liquid coating,
4. Significance and Use
4.1 This test method is intended to provide a measure of the volume of dry coating obtainable from a given volume of liquid coating. This value is useful for comparing the coverage (square feet of surface covered at a specified dry film thickness per unit volume) obtainable with different coating products.
4.2 For various reasons the value obtained may not be equal to that predicted from simple additivity of the weights and volumes of the raw materials in a formulation. One reason is that the volume occupied by a solution of resin in solvent may be the same, greater, or less than the total volume of the separate ingredients: such contraction or expansion in resin solutions is governed by a number of factors, one of which is the extent and direction of spread

between solubility parameters of the resin and solvent, 4.3 The spatial configuration of the pigment particles and
the degree to which the spaces between the pigment particles are filled with the binder also affect the volume of a dry coating formulation. Above the critical pigment volume concentration, the apparent volume of the dry film is significantly greater than theoretical due to the increase in unfilled voids between pigment particles. The use of volume nonvolatile matter values in such instances should be care fully considered as the increased volume is largely due to air trapped in these voids.
5. Apparatus
5.1 Analytical Balance. 5.2 Steel Disk, preferably stainless steel, 23/s in. (60 mm) in diameter and 22 gage (0.65 mm) in thickness with a small hole near the circumference. A fine wire, such as Chromel A, 28 gage (0.32 mm), is attached through the hole and made the appropriate length for subsequent suspension of the disk in a liquid. The wire should have a small loop on the upper end so the disk and wire can be hung by this loop on the? balance.
N' 4--Instead of steel disks, some analysts use aluminum tubes.
In the round-robin results, essentially no difference was found in the precision obtained by both methods. Source and dimensions of these tubes are described in the annex.
5.3 Counterweight, to be placed on the balance stirrup after hanger bow and pan are removed.
5.4 Beaker, 1-L--For-easier manipulation during the weighing of disk in liquid it is advisable to cut the beaker to a height of 4V2 in. (115 mm).
5.5 Support for holding the beaker under the balance stirrup without jamming the pan damper in the floor of the balance. A cork or neoprene ring is suitable when a single-pan balance is used.
5.6 Weight per Gallon Cup, aerometer, or other suitable means for determining the density of the coating material and the suspending liquids if not known.
6. Volume Determination of Uncoated Disks
6.1 Dry the disk in an oven at 110 5C for iO min. Cool and weigh the disk in air.
6.2 Weigh the disk in the liquid to be used for suspension of the coated disk. If water is used as the suspending liquid, a few drops of wetting agent (Note 2) added to the liquid will help to ensure rapid and thorough wetting of the disk. Be careful that no air hubbies form on the disk or wire. Mark the level of liquid in the 1-L beaker necessary for complete immersion of the disk which should be at least % in. (20 mm) above the disk. Maintain this level in subsequent weighings when the disk is coated.
6.3 Record the temperature of the liquid. Obtain the density of the liquid at the temperature used, from a table, such as is found for pure water in Handbook of Chemistry and Physics,s or determine it to 0.001 g/mL.
6.4 Calculate the volume of the disk, G, in millilitres as follows:
G -- (w, -- w 2)/D
5 CRC Press, Inc., West Palm Beach, FL, 19S6.
where: w{ -- weight of disk in air, g w2 = weight of disk in liquid, g, and D = density of liquid at temperature of test, g/mL.
7. Procedure
7.1 Take a representative sample of the liquid coating ia
accordance with Practice D 3925. Mix thoroughly before
taking specimens for the individual tests.
I
7.2 Determine the weight nonvolatile of the liquid coating 1
by drying 1 h at 110 5C in accordance with Test Method f
D 2369.
I
N' 5--If this method does not apply, then the method used if
should be agreed upon between producer and user.
K
7.3 Determine to 0.001 g/mL the density of the liquid I
coating in accordance with Test Method D 1475.
1
7.4 Dip the disk in the liquid coating and allow the liquid 1
to come up on the wire a distance from `A to lh in. (5 to 15
mm). Allow about 10 min for draining, and blot the coating ft
material off the bottom edge of the disk so that beads or 1
drops do not dry on the bottom edge of the disk.
I
N' 6--In some cases the paint or varnish may be of such 1
consistency that the amount of solid matter remaining on the disk after i dxying is too small for an accurate volume determination. The use of a 1 flat pan with a sidewall about 10 mm in height in place of the disk 1
enables the operator to obtain a more desirable volume of solid matter. ; |
However, extra care must be observed to prevent trapping of air at the ; f
point where the sidewall meets the bottom ofthe pan. In no case should |
bubbles be allowed to be present in cast films. This procedure has not (
been evaluated and no precision statement is available.
f
7.5 When beads or drips stop forming, hang the disk in I
the oven for 1 h at 110"C (Note 5). Remove and cool. Weigh t
the coated disk in air.
[
7.6 Weigh the coated disk in the chosen medium in the `
same manner as for the uncoated disk, recording the |
temperature of the liquid at the time of the test.
f
8. Calculations
8.1 Calculate the volume of the coated disk, H, in millilitres, as follows:
H = (w3 - w^/D
where: w3 = weight of coated disk in air, g,
w4 = weight of coated disk in liquid, g, and
D ~ density of liquid at temperature of test. 8.2 Calculate the volume of the dried coating, F, in

8.4 Calculate the percent volume nonvolatile content in a liquid coating as follows:

j Selection of Test Methods and Significance and Use
5.1 All of the methods provided involve comparisons 'tween the spectra or chromatograms of the reference and (est samples to determine if they show significant differences. It is not possible at this time to establish quantitative limits js a guide to whether a spectral or chromatographic differ ence is truly significant. Certainly the presence or absence of a moderate or strong peak in the test sample which is not evident in the reference is significant. A persistent difference in the ratios of two peaks of one spectrum as compared to [he reference sample is significant. On the whole, some judgment must be exercised in this respect and it is advisable io refer to published data on infrared or gas chromatography ia order to establish, where feasible, the possible overall nature of the adulterant or its functional group which might be causing the comparison spectra to differ.
5.2 Method A is rapid and the most convenient of the procedures given. It should be utilized first in order to detect nonuniformity of the test sample. Significant spectral differ ences from that of the reference sample can be taken as an indication of adulteration and in such cases the use of the other methods is not necessary. As a general rule. Method A is sufficient to detect gross or major adulteration of the vehicle solids. However, where Method A shows no signifi cant spectral differences, it cannot be assumed that the test sample is completely acceptable since changes in the type of drying oil, polyol, and certain dibasic adds in alkyd resins, addition of certain aliphatic or nonfunctional hydrocarbon resins, and many minor adulterations may not always show characteristic infrared spectral differences. Therefore, in such cases it is best to proceed to additional tests as given in Methods B and C or else alternatively directly to Method D.
5.3 Method B is useful in detecting adulterations that are ^saponifiable or else have an unsaponifiable component that has escaped deteaion in Method A only because the adulterant may have been small in amount and therefore its strong spectral peaks may have been masked over by the rest of the vehicle solids. Some care should be taken in inter preting spectral differences in Method B to avoid an errotcous conclusion that the test sample is unacceptable be muse its spectrum is different. Apparent but unreal differences can occur as a result of incomplete saponificahn, failure to remove all saponifiable material, and varying
degrees of contamination of the unsaponifiable fraction with sterols, etc., present in the vehicle solids. After it has thus been firmly established that a real spectral difference does exist, further tests are unnecessary, except that it is wise to resort again to the published literature on infrared to attempt to identify the possible nature of the adulterant. Where Methods A and B indicate acceptability of the test sample, it is still not always possible to rule out adulteration caused by changes or modifications in the saponifiable portion, that is, the type of fatty acid, dibasic acids, and polyol. In such cases, it is best to continue on to Method C for determination of the oil acids, and to other gas chromatographic methods for the polyol and dibasic acids when such equipment is available.
5.4 Method C is extremely sensitive in detecting adultera tions and changes that have been made in the oil or fatty acid portion of the vehicle solids. It can, for example, detect whether linseed, coconut, oiticica, etc., has been substituted for soya oil and vice versa, or whether fish or tall oil has partially or wholly replaced some other drying oil, etc. Consequently, when the results of Methods A and B suggest that the test sample is acceptable and where a drying oil component is known to be present, Method C should be used additionally for more complete assurance of produa uniformity. Where the results from Method C along with those from Methods A and B indicate product uniformity, it is a fairly safe assumption that the product has not been significantly altered.
5.5 Method D is intended as an alternative to Methods B and C and where the results from Method A indicate apparent product acceptability. Method D, by the use of quantitative ultraviolet spectral absorbance data, is an ex tremely sensitive procedure for the detection of complete or even partial adulteration of the test sample. However, considerable caution must be exercised in the preliminary pre-drying of the vehicle solids since it is at this stage that the components are extremely sensitive to oxidative changes. Even minor oxidative changes can seriously affect the absorbance data obtained in ultraviolet spectral analysis and may give an impression that the two samples being com pared are different when in fact they are the same. When these considerations are provided for, and the comparison spectra are identical in Method D as well as in Method A, then it can be assumed that the sample is acceptable. Significant differences in the spectra from Method D would indicate nonuniformity of the product even though Method A may fail to reveal such nonuniformity.
6. Reference Sample
6.1 The reference sample of traffic paint should be at least '/i pt (250 mL) and should be truly representative of the initial paint found acceptable in pre-qualification laboratory or field service tests, or both, and which paint is subsequently specified for purchase.
6.2 In cases where paint is purchased on the basis of formulation specifications and it is desired to utilize these procedures to detect adulteration in delivered lots of paint, reference samples may be synthetically prepared to represent the extremes of the range that will be permitted in the formulation.

7. Test Sample
7.1 The test samples of the traffic paint should be at least Vi pt (250 mL) and should be representative ofeach delivered lot of paint that was specified for purchase and which is intended to be the same as the initial reference paint used in the pre-qualifications acceptance tests from which a refer ence sample was retained.
8. Sampling Reference and Test Samples
8.1 Test and reference samples of the traffic paint should be obtained in accordance with Recommended Practice E 105.

METHOD A--INFRARED SPECTRAL ANALYSIS OF TOTAL VEHICLE SOLIDS
10. Apparatus
~
10.1 Infrared Spectrophotometer, recording double-beam, and accessory equipment as described in Test Method
D2621.
11. Procedure
11.1 Obtain the infrared spectra of a cast film of the vehicle solids of both the test and reference samples by utilizing the procedure referred to in 10.1. In all cases, however, the spectral intensity of both samples should be well matched (by adjusting the film thickness) to within 5 % transmission of each other at the strongest peak, and the transmission of this peak shall be between 5 and' 15 %. It is also desirable to obtain additional spectra on thicker films or else ordinate scale expansion if available, to bring out spectral differences in the weak to moderate peak areas. Here again, the same degree of care should be taken as above to match the film thickness and thereby the overall spectral intensities of the two samples. If desired, an aid in compar ison is to run the test sample against the reference sample in the reference beam in order to show significant differences by means of a single differential spectrum. Considerable caution is required in the use and interpretation of differential spectra as well as proper adjustments ofgain, speed, and slit programs.
12. Interpretation of Results
12.1 Compare the companion spectra from the test and reference samples for identity by visual inspection preferably over a light box. Note particularly the presence- of an extraneous peak or peaks in one which is (arc) not in the other. Also note the ratio of intensities pf two adjacent or pairs of peaks on one spectra and determine whether this ratio is similar on the comparison spectra. Any significant difference should be considered as an indication of lack of uniformity between the reference and test samples. Attempt to ascribe this difference to some extraneous component or formulation difference between the comparison samples by referring to available infrared literature and published spectra. Where it is evident that the comparison spectra are significantly different, no further tests are necessary. When
the spectra are identical, proceed to Methods B and C alternatively to Method D for a fuller evaluation of possible' minor or more sophisticated adulteration.
METHOD B--INFRARED SPECTRAL ANALYSIS OF UNSAPONIFIABLE MATTER FROM VEHICLE SOLIDS

15. Interpretation of Results
15.1 Compare the percentages of unsaponifiable matter Compare the Spectra and interpret the results in a sin manner as in 12.1. Care should be taken to avoid erroneous conclusion that the materials are different when \ fact they are the same. Such a misinterpretation could" caused by incomplete removal of oil acids and varyL degrees of sterol contamination, solvent residues, etc. If it ' firmly established that the companion samples are trul different, then further tests are unnecessary. If, on the oth . hand, the spectra and unsaponifiable contents are identical and the results from Method A were similar, then proceed Method C to determine adulteration of the oil fraction or I oils if such is present or suspected of being present.

LYSIS
20. Procedure
20.1 On a portion of the previously separated vehicles of the test and reference samples, determine the nonvolatile content by means of Test Method D 1259. On the basis of Oiis determination, quantitatively weigh out, by difference, from the stoppered bottles of the total vehicle, samples to yield 0.2 0.0005 g of vehicle solids and place in a 100-mL beaker. Take care to avoid weighing errors caused ( by evaporation of solvent in the stoppered bottle during*'the
weighing process. 20.2 Evaporate the volatile material by placing the beaker
over an even heat source maintained at 60 to 65C and under a constant blanket of dry, inert gas, preferably nitrogen, fed through a bell jar in which the beaker is placed. The bell jar
should also be fitted with a stoppered separatory funnel with its delivery tube directly over the beaker. Evaporate until all the solvent is completely removed but avoid excessive exposure to these conditions much beyond this point. With the inert gas flow uninterrupted, transfer about 25 to 30 mL of spectral grade cyclohexane to the beaker through the assembled separatory funnel. Remove the beaker and imme diately stir to dissolve all the solid material in the solvent Quantitatively transfer to a 50-mL volumetric flask and fill to mark with additional spectral solvent. This yields a 0.4 % stock solution (wt/vol) of the vehicle solids in solution. If solution is not complete, try gentle warming or else start over using another suitable spectral grad? nonaromatic solvent with an ultraviolet cut-off point at least as low as 220 or 230
nm. 20.3 With appropriate calibrated pipets or hypodermic
syringes, volumetric flask, and the same lot of solvent used before, prepare several dilute quantitative solutions from aliquots of each stock solution that will enable quantitative measurements of all peak heights in the subsequent ultravi olet analysis (Note 1). In all cases, a specific quantitative dilution of the reference sample should be matched by exactly the same dilution of the test sample. For each such
matched dilution, use the exact same pipet for the test sample as was used for the reference sample to avoid dilution errors of comparison samples.
N ' 1--The concentrations and numbers of dilute solutions neces
sary to obtain all the spectral peaks characteristic of a material will vary with the type of vehicle solids under examination. Generally, three dilutions of each stock solution to yield 0.03, 0.01, and 0.005 % solutions should suffice.
20.4 Within 24 h, and after making certain that the dilute solution is perfectly clear and without sediment and insolubles, record the ultraviolet absorbance spectrum of the dilute solution using a 1-cm stoppered quartz cell against the solvent blank in a reference cell. Obtain all absorbance peaks for each material that may occur between 200 and 300 nm. By appropriate use of the various dilutions of each sample, the spectral peaks should be made to fall between 0.3 and 0.8 absorbance unit. In all cases, record the exact absorbance value for each of the peaks for both test and reference samples. For each peak at a specific wavelength, the concen trations used for both the test and reference samples should be identical. It is wise to prepare several replicate standard stock and dilute solutions for each concentration indepen dently ofeach other in order to obtain an idea of the range in each peak absorbance of the standard sample that might be expected in this procedure, especially as a result of the preliminary removal of original solvent by heating and its possible oxidative effects.
21. Interpretation of Results
21.1 Compare the nature and shape of the ultraviolet absorption curves obtained for both the test and reference samples. Any significant difference is an indication of adulteration or nonuniformity. Also compare the absorbance value of each peak given by the test sample with that given by the comparison reference sample. Any significant differ ence should be an indication of adulteration or nonuni formity. It is difficult to fix precise criteria for spectral differences that apply to all materials. As a general guide, the following criteria may be useful for evaluating comparable absorbance peaks. Comparison peaks should be within 0.05 absorbance units when occurring between 220 and 350 nm, and within 0.08 at lower wavelengths.
22. Report
22.1 Indicate uniformity or lack of uniformity of the vehicle solids of the test sample with respect to the reference sample and the method or methods (A, B, C, and D) used for this judgment. If possible, attempt to report the nature of possible adulterant(s) present or the cause of the nonuni formity.

Designation: D 2793 - 69 (Reapproved 1987)
Standard Test Method for Block Resistance of Organic Coatings on Wood Substrates1
This standard is issued under the fixed designation D 2793; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year oflast revision, A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope 1.1 This method covers the determination of the block
resistance of organic coatings on wood and wood-based substrates. Block resistance is the ability of a coating to resist sticking to another surface and to resist any change in appearance, when it is pressed against that surface for a prolonged period of time.
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
2. Summary of Method
2.1 The coatings to be tested are applied to the desired substrate. They are cured in a manner duplicating the condition of end use as much as possible. Then a stack of these painted substrates is formed and subjected to a specified pressure for a sufficient time to develop any sticking tendencies that exist. The pressure is released and the painted surfaces are examined for any signs of sticking. If blocking (forming a block by panels sticking together) occurs, the material is unsatisfactory. If no sticking or damage to the film surface occurs, the material is satisfac tory.
2.2 When the conditions of production finishing are established and known, the method of application, the substrate, film thickness, and cure of the film should duplicate those conditions as closely as possible.
2.3 When the conditions of storage and shipment are established and known, the temperature, relative humidity, duration, and pressure used for the test should duplicate those conditions as closely as possible.
3. Apparatus
3.1 Rigid Platens, 4-in. (100-mm) square, capable of being maintained at 120 2F (49 TC).
4. Test Specimens
4.1 For those cases where the intended use conditions are not established or known, the following specifications or some set of specifications agreed upon by the purchaser and seller apply: The test coating shall be applied by normal spray, using air, to a 4 by 4-in. (100 by 100-mm) panel. The panel shall be a piece of 'A-in. (6.4-mm) SIS (smooth one

side) standard hardboard. The dry film thickness of pig. I
mented coatings shall be 1.5 0.2 mils (38 5 (am), and of ; clear coatings shall be 1.2 0.2 mils (30 5 jam). Cure of the coating shall be as agreed and should be standardized for ! each coating.
N' 1--Film thickness can be measured by weight difference
before and after painting, but this requires careful conditioning of the substrate under standard temperature and humidity conditions prior to
each weighing. Film thickness can also be determined by using an aluminum tab alongside the test panel and measuring the film thickness with a standard eddy-current gage or using a steel panel with a magnetic film thickness gage.

5. Procedure
5.1 After 90 s cooling under ambient conditions or as
agreed upon, make a stack of six panels and place under a
uniform pressure of 35 2 psi (240 20 kPa) for Class 1,20 j
1 psi (140 10 kPa) for Class II, and 5 `A psi (35 1.7 '
kPa) for Class III. These classes are arbitrary and simply
designate three groups of coatings or possibly three groups of
end uses. Stack the panels in the following order from the top
to the bottom:
i
{a) Face down.
(b) Face down
;
(c) Face up.
(d) Face down.
(e) Facedown.
|
(/) Face up.
This provides for two face-to-face contacts and two face- ;
to-back contacts. Apply the load through rigid 4-in. square j
(100-mm square) pressure plates. Apply the load for a j
minimum of 24 h. Other pressures, types of pressure plates, 1
and times may be used if agreed between the purchaser and ;
seller. Conduct the test under ambient conditions but use ;
press platens heated to 120 2F (49 1C). Slip sheets :
should not be used unless they are known to be used during
storage of shipment.
N' 2--The most difficult portion of this test method to Stan-
dardize on intelligently is the proper pressure to employ. Stacking j pressure in production would be calculated as follows:
(DHA\/A2) x F
where: D = board density, H = height of stack, A, = area of stack, A2 - area of support, and F = safety factor. The area of support is difficult to establish. In some instances board is

No t e 3--Many coatings are plasticized if they are contaminated with water. Ifpossible, therefore, it is advisable to run blocking tests at as jjgh relative humidities as might be encountered in production of warehousing.
No t e 4--Blocking tests shall be run with panels wet with water, if water quenching is used for cooling the boards and die boards are wet when stacked in production.
5.2 At the end of the test period remove the pressure and pick up the stack in such a way that first the bottom panel, then the next to the bottom panel, and eventually all of the panels are free to fall of their own weight. This falling free is considered as passing the test if there also is no change in the appearance of the coated surfaces of any of the panels.
6, Report
6.1 This is a go/no-go test for both face-to-face and face-to-back conditions. In addition to the separate state ment of satisfactory or not satisfactory under both of these conditions, the nature of the failure should be reported. The report should also include the particulars of the test as follows:
6.1.1 Type of substrate, 6.1.2 Method of application, 6.1.3 Curing cycle, 6.1.4 Film thickness, 6.1.5 Temperature, humidity, and pressure of the blocking test, 6.1.6 Type of stacking including identification and type of slip sheets if any, and 6.1.7 Duration of test.

3. Terminology 3.1 Description of Term Specific to This Standard: 3.1.1 impact resistance, of a coating--the number of
inch-pounds (kilogram-metres) required to produce cracking in the deformed coating.
4. Summary of Test Method
4.1 The organic coatings under test are applied to suitable thin metal panels. After the coatings have cured, a standard weight is dropped a distance so as to strike an indenter that deforms the coating and the substrate. The indentation can be either an intrusion or an extrusion. By gradually in creasing the distance the weight drops, the point at which failure usually occurs can be determined. Films generally fail by cracking, which is made more visible by the use of a magnifier, by the application of a copper sulfate (CuS04)

;4-gage (0.025 in. or 0.63 mm) steel panels treated with a c0l)version coating in accordance with Procedure A of practice D 609, unless otherwise specified. Prepare a min ium of four coated panels for the material.
N' 1--The coatings should be applied in accordance with Test wjthods D 823, or as agreed upon between the producer and the user. Other gage steel panels may be used if agreed upon between the producer and the user.
8.2 Cure the coated panels under conditions of humidity afld temperature agreed upon between the producer and the
user-
N' 2--The thickness of the dry coatings should be measured in accordance with Test Methods D 1186.
9, Conditioning
9.1 Unless otherwise agreed upon between the producer ppd the user, condition the coated test panels for at least 24 h at 73.5 3.5F (23 2"C) and 50 5 % relative humidity. Conduct the test in the same environment or immediately 0n removal therefrom.
jO. Procedure
10.1 Install the punch having the head diameter specified or agreed upon. Place the test panel in the apparatus with the coated side either up or down as specified or agreed upon. Be sure the panel is flat against the base support and that the indenter is in contact with the top surface of the panel. Lightly place the weight on the indenter and adjust the guide tube so that the lifting pin is at the zero mark. Raise the weight up the tube to a height where it is expected that no failure will occur. Release the weight so that it drops on the indenter.
10.2 Remove the test panel from the apparatus and observe the impact area for cracks in the coating. If no cracks are evident, repeat the procedure at a greater height, in creasing 1 in. (25 mm) at a time. Once visible cracks are observed, repeat the test five times at each of three heights; slightly above, slightly below, and at that determined in the first trial. Test in a random fashion so that all impacts from one height are not made in succession or on one panel.
10.3 Examine the impacted areas for cracking by one of the following methods;
10.3.1 Use a magnifier to examine the area for cracks. 10.3.2 Hold a white flannel-type cloth saturated with the acidified copper sulfate (CuS04) solution (7.1) over the
impacted areas for at least 15 min. Remove the cloth and examine both the test areas and cloth for. evidence of copper deposition or iron-rust staining respectively.
N' 3--The. copper sulfate solution will not perform properly on zinc-phosphate-treated metal unless the conversion coating cracks.
10.3.3 To detect breaks in the film with a pin hole detector, first connect the ground lead from the instrument to the bare substrate and connect the instrument to an electrical power source. Moisten the probe sponge with tap water and slowly draw the probe over the impact area. The presence of cracks will be indicated by an audible alarm.
10.4 For each inch-pound (kilogram-metre) level, tabulate the number of times the coating passed or failed. The value where the results change from mainly passing to mainly failing is the impact failure end point.
11. Report
11.1 Report the following for each coating tested: 11.1.1 The inch-pounds (kilogram-metres) at the impact failure end point, 11.1.2 Whether intrusion or extrusion was used, 11.1.3 Diameter of the punch used, 11.1.4 Thickness of coating, 11.1.5 Substrate thickness and type of metal, 11.1.6 Method of panel preparation, and 11.1.7 Atmospheric conditions under which the coated panels were conditioned and tested.
N' 4--Because of the poor reproducibility of this method, the reporting of inch-pounds (kilogram-metres) in comparing coatings for impact resistance should be restricted to one laboratory. For interlabo ratory comparisons, rankings ofcoatings for impact resistance should be reported.
12. Precision
12.1 On the basis of an interlaboratory test in which operators in six laboratories tested three paints having a broad range of impact resistance on two metal substrates, the between-laboratories coefficients of variation were found to be as follows:
Brittle coating (less than 6 in.-lb) Average coating (between 6 and 140 in.-lb)
Flexible coating (more than 140 in.-lb) (0.625 in.-diameter punch)

corrosive atmosphere to initiate corrosion. The specimens are then exposed to controlled temperature and humidity conditions known to be conducive to filiform corrosion.
3.2 In Procedure A, panels are subjected to a preliminary exposure in the salt spray cabinet to initiate corrosion, rinsed, and placed in a humidity cabinet. In Procedure B, based on ISO 4623, panels are either exposed to salt spray or dipped in a salt solution but not rinsed before placing in the humidity cabinet operated at a higher temperature than in Procedure A.
4. Significance and Use
4.1 Some organic coatings applied to metal substrates exhibit filiform corrosion when there is a break in the coating film and the relative humidity is in the 70 to 95 % range.
4.2 This method can be used to determine the suscepti bility of organic coated metal substrates to the formation of filiform corrosion.
5. Definitions
5.1 filiform corrosion--a special type of corrosion that occurs under coatings on metal substrates that is character ized by a definite threadlike structure and directional growth. Filiform corrosion usually occurs between 70 and 95F (20 and 35C), with a corresponding relative humidity range of 60 to. 95 %; above 95 % humidity, blistering rather than filiform corrosion may occur.
6. Apparatus 6.1 Salt-Spray Chamber as described in Method B 117,
for salt-spray (fog) testing.
N' 1--The preferred initiator of corrosion at the scribe is the
salt-fog atmosphere described in Method B 117. Exposure of the specimens for 2 to 4 h in a closed cabinet to the atmosphere above a 1 % acetic acid solution is an acceptable alternative.
6.2 Humidity Cabinet--Any cabinet with suitable tem perature and humidity controls with air circulation may be used. The size and detailed construction of the apparatus are optional, provided the conditions meet the requirements of this method.
7. Test Specimen
7.t The composition, surface preparation, and number of test specimens shall be agreed upon between the producer and the user. Steel is the preferred substrate, but other metals such as aluminum, copper, and stainless steel may be used. Zinc and 'zinc-coated steel are not recommended because filiform corrosion generally does not occur on zinc.
N' .2--Applicable test panel description and surface preparation
methods are given in Method D 607 and Practices D 1730.
7.2 Preparation ofTest Specimens--The method ofappli cation, film thickness, curing, and conditioning shall be agreed upon between the producer and user.

N' 3--Test Methods D 823 gives application methods that can be
used to produce films of uniform film thickness.
N' 4--Test Methods D 1005, D 1186, and D 1400 give proce
dures that can be used for measurement of dry film thickness.
7.3 Scribe the test specimen in accordance with Method D 1654 or as agreed upon between the producer and user.
7.4 The back and edges of the panel should be protected with an anti-corrosion coating or tape, unless edge failure is being evaluated.
g. Procedure A
8.1 Expose the test specimens to the salt-fog atmosphere in accordance with Method B 117 for at least 4 h and not more than 24 h, or as agreed upon between the producer and
user. 8.2 Remove from the salt-fog cabinet and thoroughly
rinse with distilled or demineralized water. Do not permit specimens to dry before placing in the humidity cabinet.
8.3 Place the specimens in the humidity cabinet sd they are no closer together than 1.5 in. (40 mm) and not in contact with any metal. Operate the cabinet at 77 3!F (25 2C) and 85 2 % relative humidity unless otherwise agreed upon between the producer and user.
N' 5--The recommended means of maintaining the specified
relative humidity is to utilize trays of saturated potassium chromate solution (650 g/L). Recommended Practice E 104 describes other methods for maintaining relative humidity, but they may affect the degree and rate of filiform corrosion.
8.4 Inspect the specimens at intervals of approximately 168 h for development of threadlike filaments from the scribe. Exercise care to maintain wetness of specimens during inspection, since drying stops the original pattern of filiform corrosion. New filiform, may develop on continued exposure but at different points.
8.4.1 Filiform corrosion will be noted as threadlike fila ments (see Note 6), initiating at the scribe. A standard method of rating failure due to filiform is not available. The uniformity of filament growth in direction, width, height and frequency precludes a precise rating system. Photographs of filiform failure are preferred for recording test results. Otherwise, a brief description of the filament growth and their frequency can be made.
N' 6--The nature of grinding and grain direction on panels can
influence the direction of filiform growth.
8.5 The normal test period is 6 weeks (1008 h). Other periods may be used at the option of the producer and user.
9. Procedure (ISO 4623)
9.1 Two alternative initiations of corrosion are available, based on initiation by dipping in sodium chloride solution (see Note 7) or exposure to salt fog. The dipping technique is
generally preferable for air drying and low-durability mate-
rials. For high-durability systems such as automotive finishes applied to phosphated steel, the dipping technique may not produce filiform corrosion and. for these systems, it is preferable to adopt the salt-fog technique. In such cases, the necessary period of exposure to salt fog depends on the durability ofthe material under test but should rarely need to exceed 24 h.
N' 7--Sodium chloride 0.1 % (w/v) solution (for dipping tech
nique] is prepared by dissolving 1 g of reagent grade sodium chloride (NaCI) in 1 L ofdistilled or demineralized water. Place this solution in a vessel suitable for complete immersion of the test panel
9.2 Dipping Technique: 9.2.1 Immerse the scribed specimen for 30 to 60 s in the sodium chloride solution (see Note 7). 9.2.2 Take the specimen out of the solution and remove any drops of liquid adhering to it, taking care not to remove the solution from the scribed marks. 9.2.3 Place .the specimen in a humidity cabinet main tained at 104 3.5F (40 2C) and 80 5 % relative humidity. 9.2.4 Repeat the immersion procedure every 3 or 4 days until the end of the test cycle (21 days) or as agreed upon between the producer and the user. 9.3 Salt-Fog Technique: 9.3.1 Expose the scribed test specimen to the salt-fog atmosphere in accordance with Method B 117 for at least 4 h or not more than 24 h or as agreed upon between the producer and the user. 9.3.2 Remove the test specimen from the salt-fog cabinet and remove any drops of liquid adhering to it, taking care not to remove the solution from the scribed marks. 9.3.3 Place the specimen in a humidity cabinet main tained at 104 3.5F (40 2C) and 80 5 % relative humidity for the specified period agreed upon between the producer and the user. 9.4 Follow the procedures in 8.4 and 8.4.1.
10. Report
10.1 The report shall include the following: 10.1.1 Initiation procedure, 10.1.2 Humidity cabinet operating temperature, 10.1.3 Exposure period, and , 10.1.4 Rating of coatings as described in 8.4.1.
11. Precision
1J. 1 Procedure A--Twelve laboratories,, using three types of cofrosion initiations, three coatings and three substrates, were in excellent agreement in their ranking of the suscepti bility to filiform corrosion by this procedure.
11.2 Procedure B--Has been judged reproducible by Working Group 2 of ISO/TC35/SC9.

Using equations deprived from Kubelka-Munk turbid media theory (1-4)2, the reflectance of a coating can be predicted for any film thickness from measurements made at only one. On this basis several easy and accurate test methods (5,7) have been developed for determining hiding power. In the past such test methods have been considered difficult due to complexities, apparent and actual, in the treatment of data. The present test method has been simplified in this respect, primarily by
adapting it fully for computer calculations. Although the use of broad-band reflectometry makes this test method theoretically valid only for
nonchromatic (white or gray) colors, good agreement has been obtained with chromatic paints as well. This is undoubtedly because the experimental measurements are made fairly close to the hiding power end point so that the Kubelka-Munk extrapolation and thus any associated error is
relatively small. This test method is therefore recommended without restriction as to color.
1. Scope
1.1 This test method covers the determination, without reference to a material paint standard, of the hiding power of air dry coatings with Y tristimulus values greater than 15 %. With appropriate modification, it can also be used to test baking finishes.
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

7.1 General Instructions: 7.1.1 Film Application--Drawdowns should be made manually with a smooth uniform motion, at the rate of about 6 cm/s. Paper charts should be held flat by a vacuum plate or other suitable device while making drawdowns. 7.1.2 Reflectance Measurements--Measure the reflec tance of each test area at a minimum of three locations, reading or estimating to four decimal places and calculating mean values to the same. Charts should be placed over a
white surface and black glass over a black surface while
5. Significance and Use
measurements are being made.
5.1 This is a precise instrumental method giving results having an absolute physical significance without reference to a comparison paint. It should be used when maximum precision and minimum subjectivity are required, as in testing specification coatings or evaluating the hiding effi
ciency of pigments. 5.2 Hiding power Test Method D 344 is visual instead of
instrumental, and gives results that are relative to a material standard instead of absolute. It is less precise than Test Method D 2805 but more closely aligned with practical painting procedures.
7.1.3 Record Keeping--All data should be recorded on a copy of the worksheet form specified in Fig. 1. Typical data entries are shown in Fig. 2.
7.1.4 Weight Measurements--Make all weighings to 0.1 mg on the analytical balance.

weighed slides, squeezing them together so that ther paint spreads to a diameter ofabout 45 mm. Reweigh to obtain the weight of paint sample. Separate the slides, allow the films to dry, and weigh a third time to determine the dry weight. Then calculate the nonvolatile content of the paint as a decimal fraction to four places. Run in duplicate and report the mean value to three decimal places on Line B of the worksheet (Fig. 1).
7.4 Applicator Selection--Make trial drawdowns on black
and white charts at clearances of 100, 150, and 200 pm. Allow them to dry overnight and measure their contrast ratios. Based on the results select the best applicator for a contrast ratio of 0.97 0.01, which may be one of the trial applicators or one of intermediate clearance. If it seems necessary, make an additional trial drawdown to confirm the correct applicator.
7.5 Drawdowns on Glass and Charts--Using the appli cator selected from 7.4, make four drawdowns each on black glass and on black and white charts in accordance with.7.1.'l.
Leave enough of the white area of each chart uncoated to permit measurement of the reflectance W.
7.6 Drying of the Films--Immediately after application place each drawdown horizontally in a well-ventilated dustfree location, with all drawdowns in close proximity to one another to assure identical drying conditions, and allow to dry a minimum of 40 h before testing.
7.7 Reflectance Measurements--On the second or third day after application measure the reflectances on all of the drawdowns within as brief a time span as possible, alter
nating the measurements, between charts and glass rather than doing first all one and then the other. Enter the values of Rq , Rw, and W for charts into Section D of the worksheet, and the values of Rq for glass into Section E.
7.8 Weight of Dry Film, M--After all of the reflectances are measured, position the template on the glass panels, each in its turn, and scrape off the surplus paint with a razor blade, to leave film areas defined by the template. If the template area is not already specified, measure one of the

3, Significance and Use
3.1 Although chlorinated phenol-treated wood has be come less common due to environmental concerns, repel lent-treated wood is commonly specified in construction. This test method provides a means to verify the presence ofa significant level of water repellent protection.
4. Apparatus
4.1 Eyedropper, plastic squeeze bottle or similar means for metering drops of water.

mately. 1 in. (25 mm) in diameter to be used as a holder for the coil.
4.4 Sharp Knife. -
5. Water Repellent Test
5.1 Place uncut wood items to be tested so that the end grain is exposed as a horizontal surface. If the end grain cannot be so positioned, comparisons can be made on the flat grain.
5.2 With an eye dropper, or similar device, allow several drops of water to fall from about lh in. (13 mm) on the end grain of the wood. Wait 5 min and then observe the degree of penetration. With flat grain or vertical grain surfaces, waiting periods of 10 to 15 min may be necessary.
5.3 Water drops that immediately flatten out, penetrate and darken the wood, indicate that the wood has not been treated with a water repellent.
5.4 Water drops that "bead-up" and remain as spheres, with little or no color change or penetration, indicate that the wood has been treated with a water repellent. Water repellent preservatives, meeting Fed. Spec. TT-W-572 and NBS Stan dard 262-63, impart sufficient water repellency to the end grain of wood to cause water drops to bead up and form spheres.
6. Preservative Test
6.1 Chlorinated phenol based wood preservatives emit a characteristic green flame upon pyrolysis within a ventilated copper envelope due to the release of chlorine and its consequent reaction with copper (Beilstein's test). Untreated wood produces a yellow-orange flame but any chlorine containing compound will give a positive test.
6.2 Using the copper wire specimen holder, described in 3.3, hold the coil portion id the flame until it bums with a characteristic yellow-orange color. This preheated coil is then allowed to cool.
6.3 With a knife, cleaned by heating after each use, cut a splinter from the specimen of wood to be tested. Samples should be taken near the end of the wood items where end grain is exposed and where normal concentration of the preservative chemicals is greatest. The size of the wood sample should be smaller than the length and inner diameter of the coil.
6.4 With the copper coil held horizontally, place the splinter in the center of the coil. Put the copper coil with wood splinter in the flame and bum. If chlorinated phenols are present, the characteristic green flame is produced. Untreated wood produces the yellow-orange flame.
7. Accuracy
7.1 The tests are less accurate on flat grain and the

heartwood of some wood species, so that ehd grain and
sapwood should be used whenever possible. 7.2 Tests on both a known untreated sample and a treated
sample of the same wood species will provide comparison standards for the operator and will improve the accuracy of
the tests. 7.3 Test results are improved if tests are made with wood
samples taken from the center ofa stack or from a protected area where the possibility of contamination is least Untreated items which come in physical contact with pre
servative treated products during handling and shipping m-
show slight evidence of the preservative chemical.

7.4 More than one wood sample obtained from differem areas from the unknown piece should be tested.

be used. For instance, a latex paint with good sealing properties may be required for porous surfaces, such as new dry wall, bare plaster, new wood or porous masonry surfaces.
4.2 Substrate Condition--Dirty, chalky, alkaline, or wa ter-soluble surfaces may affect tire practical requirements and performance of interior latex flat paints.
4.3 Application Properties--The application properties of interior latex paints are affected by temperature, humidity, and the texture and porosity of the surface to be painted. Application will also depend upon the type and quality of equipment used.
4.4 Physical Requirements--The type of latex wall paint to be used will depend not only upon the surface to be painted, but also upon the desired physical properties of the finish. For instance, if maximum light diffusion and unifor mity of appearance are the prime requirements, such as when painting ceilings, then a low sheen paint should be used. However, if cleanability or stain removal properties are desired for walls that become soiled, then a nonporous paint should be used.
5. Selection of Tests
5.1 It has been pointed out that there are many conditions that affect interior latex wall paints so that different types of latex paints have been developed specifically to meet the requirements of these various conditions.

1-gal (4-L) sample is usually sufficient-for the recommended tests, but for guidance in selecting a sampling plan, consult Recommended Practice E 105.
7. Liquid Paint Properties
7.1 Condition in Container--Thickening, settling, and separation are undesirable and objectionable if the paint cannot be reconditioned with a reasonable amount of stirring. The referenced method covers procedures for deter mining changes in properties of paints after storage. Deter mine the condition in the container in accordance with Method 3011 of Federal Test Method Standard No. 141.
7.2 Coarse Particles and Foreign Matter: 7.2.1 Paints must be free of coarse particles to form uniform films of good appearance, a typical maximum being 2 weight % of total paint. The specified test with a 325-mesh (45-um) screen and water as the wash liquid gives the percent of these particles in a latex paint. Determine coarse particles and foreign matter in accordance with Test Methods D 185. 7.2.2 Another test method used in industry to determine whether coarse particles are present in a dry film is to scrape the surface of the film with a spatula or metal edge of a ruler.
Any particles larger than 325 mesh can be clearly seen after the surface has been scraped.
7.3 Density (Weight per Gallon)--The density as mea sured by weight per gallon (kilograms per litre) is used to assure product uniformity from batch to batch. It does not necessarily measure the quality of a paint. In the referenced method, the density is expressed as the weight in pounds of 1 U.S. gal (kg/L) of the paint at a specified temperature. Most interior flat latex, paints have densities of about 10 to 12 lb/gal (1.2 to 1.4 kg/L). Determine density in accordance with Test Method D 1475.
7.4 Fineness ofDispersion:
7.4.1 The more finely a pigment is dispersed, the more efficiently it is being used. One method for measuring the degree of dispersion (commonly referred to as "fineness of grind") is to draw the material down a calibrated tapered groove varying in depth from 4 to 0 mils (100 to 0 pm). The point at which continuous groupings of particles or agglom erates, or both, protrude through the surface of the liquid is taken as the fineness reading. Lower readings in mils or micrometres or higher readings in Hegman units indicate better fineness of dispersion.
7.4.2 The referenced method was designed primarily for coatings with good fineness of dispersion, such as enamels. Most interior flat latex paints have finenesses of about 70 to 90 pm (1 to 2.5 Hegman). Although these paints may
contain pigments so coarse that it is impractical to measure the fineness with a grind gage, most of the pigmehts are so finely dispersed that particles or agglomerates cannot be seen by the unaided eye or felt on the surface of the dry film. In addition, the fast drying of some flat latex paints may make it difficult to make accurate measurements of fineness of dispersion.
7.4.3 Determine fineness of dispersion with Test Method
D 1210. 7.5 Odor--One of the advantages of latex paints is that
they do not have odors characteristic of solvent-based coatings. However, other ingredients, such as ammonia, may be used which might also be objectionable in confined spaces. Thus, interior latex paints should be tested for odor
acceptability. Although there is no adequate ASTM test method to measure odor for nonorganic solvent paints, test methods are used by industry to measure this property. Examine to determine if the paint has an unpleasant or irritating odor during application or drying.
7.6 Consistency (Viscosity)--Paints of a given type should fall within a stated consistency for satisfactory reproduction of a specific formula. While consistency is an important property it does not determine the quality of a paint and should be used mainly to assure product uniformity. In the
referenced method, consistency is defined as the load in grams to produce a specified rate of shear. Although the consistency of most latex wall paint is about 150 to 300 g/100 revolutions, a much wider range is possible because of the wide variations in rheological properties of these paints. Also two paints of the same consistency may have quite different rheological properties. Determine the consistency in accordance with Test Method D 562.
7.7 Rheological Properties, Non-Newtonian Liquids-- Rheological properties are related to application and leveling properties of the liquid paint. The referenced method covers
399
DUP0502 97580
D 2931
the determination of rheological properties and i's particu larly suited for use with paints that display thixotropic characteristics. It actually measures viscosity under varying conditions of time and rotational speed of the spindle. Determine rheological properties in accordance with Test Methods D 2196.
7.8 pH--Latex paints with low (acidic) pH may corrode the container. pH may vary from about 5 to 10 depending upon the type of latex used and the general formulation. pH does not determine the quality of a latex paint and should only be used to assure product uniformity. A change in pH during storage may indicate poor stability or a change in properties of a latex paint. Determine pH in accordance with Test Method E 70.
7.9 Color Compatibility--A test method to determine how well colorants can be dispersed in a paint so that the paint will have uniformity of color when applied is now in preparation and will be included in this guide when adopted by ASTM.
7.10 Freeze-Thaw Stability--Water-based paints may be subjected to freezing conditions during shipping and storage. Suitably stabilized paints will resist several cycles of freezing and thawing without showing deleterious changes such as coagulation, graininess, or excessive viscosity increase. Many latex paints will increase in viscosity but can still be considered usable if other properties, which may be affected by a higher viscosity, such as leveling and brushability, are satisfactory. Determine freeze-thaw stability in accordance with Test Method D 2243.
7.11 Package Stability--Since paints cannot normally be used immediately after manufacture, they must remain stable in the can for some time. At normal temperatures, most latex paints can be stored for over a year with little change in properties. Although package stability can usually be determined in several weeks at an elevated temperature such as 122F (50C), occasionally the results of the acceler ated test do not coincide with those of prolonged room temperature storage. The referenced method covers the change in consistency and in certain other properties in packaged latex paint when stored at temperatures above freezing. Determine package stability in accordance with Test Method D 1849.
7.12 Microorganism Resistance--Bacteria in a latex paint can cause gassing, putrefactive, or fermentative odors and loss of viscosity. Determine if the paint contains living bacteria or ifit is resistant to attack by bacteria in accordance with Test Method D 2574.8
8. Paint Application and Film Formation
8.1 Application Properties--Determine the ease with which a paint can be applied to various wall surfaces with brush, roller, or spray equipment, in accordance with Method 4541 of Federal Test Method Standard 141. Appli cation properties are generally compared to a standard, or described by requirements in a product specification.
8.1.1 Brushing Properties--The specified method covers the determination of the brushing properties of coatings. The test is quite subjective although someone experienced in the art can produce quite consistent results, particularly in the evaluation of "drag" properties. Determine brushing proper

viewing conditions, size of specimens, and general proce dures to be used in the visual evaluation of color differences of opaque materials. Determine color difference in accord ance with Practice D 1729.
9.2 Color Differences ofOpaque Material by Instrumental Evaluation--Color difference between a product and the standard can be measured by instrument. Generally, the tolerance is agreed upon by the purchaser and the seller and may also be required if a product specification is involved. Although color instruments are not more sensitive than the eye, they provide numerical values which can be subse quently compared to later measurements. The referenced method covers the instrumental determination of small color differences observable in daylight illumination between nonfluorescent, nonmetameric, opaque surfaces such as coated specimens. If metamerism is suspected, visual evalu ation (9.1) should be used to verify the results. Make instrumental measurement of color difference in accordance with Method D 2244.
9.3 Hiding Power (Dry Opacity)--Hiding power is the measure of the ability of a paint to hide the substrate. It is, however, dependent upon uniform film thickness which is influenced by flow and leveling. Test Method D 344 is a practical test in which paint is applied with a brush, film thickness is approximately measured, opacity is evaluated visually as compared to a standard paint, and results are affected by flow and leveling application properties of the paint. Test Method D 2805 is considered to be a more precise and accurate test that does not need a material paint standard. Paint is applied with an applicator bar to minimize the effects of flow and leveling, film thickness is rigorously measured, and opacity is instrumentally evaluated. Deter mine hiding power in accordance with Test Methods D 344 or D 2805.
9.4 Specular Gloss (Sheen)--The method given, using the 85 geometry, is useful in characterizing the low angle appearance of flat paints. Most flat latex wall paints have an 85 sheen of about 1 to 10. Although paints with good uniformity ofappearance are often paints oflower sheen and paints with good cleanability are often ones with higher sheen, this is not always the case, and the sheen of a paint should not be used as a measure of other paint properties. Determine the 85 gloss in accordance with Test Method D523.
9.5 Uniformity of Appearance--Apply the paint as in Method 4541, Federal Test Method Standard 141, and examine the dry paint to see if there is any nonuniformity of color or sheen.
10. Properties of Dry Film
10.1 Efflorescence of the Paint Film--The referenced method measures efflorescence that comes from the paint itself, not from the substrate. Few interior latex paints effloresce due to improvements in latex and latex paint formulations. Salt formation is produced by specific condi! tions of temperature and. humidity if a paint contains sufficient solid water-soluble material to cause a noticeable deposit on the film. Determine efflorescence resistance in accordance with Test Method D 1736.
10.2 Efflorescence from Substrate--Cementitious subj strates may contain sufficient solid water-soluble materials to
cause a surface deposit through leaching and evaporation. Determine if a latex paint applied over an alkaline masonry surface will allow soluble salts to pass through the film in accordance with Test Method D 2831.
10.3 Elongation--Elongation is a measure of the flexi bility of a paint film. Most interior latex paints can be bent over a 'A in. (6.4-mm) mandrel without affecting the film. Determine elongation in accordance with Test Methods D 522 or D 1737.
10.4 Film Porosity--The more porous a paint is, the worse will be its cleanability and enamel holdout. Determine the film porosity in accordance with Test Method D 3258.
10.5 Scrubbability--The ability of an interior finish to resist scrubbing is an important property. The referenced method provides a measure of the wet abrasion resistance of a film. However, wet abrasion resistance is not necessarily a measure of how well soils or stains can be removed since some paints have good scrubbability but poor stain cleanability because they are porous. The scrubbability of interior latex flat paints can vary from less than 100 to more than 1000 cycles. Determine the scrubbability in accordance with Test Method D 2486. A control paint should always be tested at the same time because of the variability of the method.
10.6 Stain Removal (Cleanability)--The ability to re move marks satisfactorily without damaging the film is an important property of interior finishes. A test method to determine how well stains and soils can be removed from a cured paint film is now in preparation and will be included in this guide when it is approved by ASTM. Test methods used by the paint industry consist of applying various household soils or stains to the cured paint film and attempting to remove these soils or stains by means of a washing or scrubbing operation. The attempted removal of the soils or stains can be done by hand or with a mechanical apparatus. Determine the relative ease of removal of soil from the dried film by washing with either an abrasive or nonabrasive cleaner in accordance with Test Method D 3450.
10.7 Wet Abrasion Resistance (Weight Loss Method)-- This method differs from Test Method D2486, scrub resistance (10.5), in that the loss in weight or volume of the paint film is recorded for each 100 scrub cycles. In Test Method D 2486 the number of scrub cycles required to wear through the paint film is recorded. Determine the wet abrasion resistance of the paint in accordance with Test Method D 4213.
11. Analysis of Paint
11.1 Chemical Analysis--If a specification requires cer tain raw materials or certain components in a given amount, then chemical analysis is required to determine whether the specified materials are present and in what amounts. Anal ysis does not necessarily establish paint quality which can also be greatly affected by manufacturing techniques. Most ASTM analytical methods apply to solvent-based coatings. However, some of them can be adapted for analysis oflatex
paints. 11.2 Volatile Content--The amount of volatile material
in a paint cannot be used as an indication of the quality of a paint. This value is useful, however, in determining the
401
DUP050297582
W > 2931
similarity df two samples. Determine volatile content in accordance with Test Method D 2369.
12. Field Testing 12.1 Although the recommended test methods attempt to
duplicate actual conditions under which latex flat wall paj
are applied, it is not possible to duplicate all ppssihf
conditions. It is therefore necessary to test latex flat
paints under actual existing conditions for a final evaluati
of the quality of a paint.

sampling, stir the paint as in 4.21 of Method 1021. Deter mine the weight per gallon (or kilograms per litre) in accordance with Test Method D 1475. Stir again and recheck
the weight per gallon. The two readings should agree within 0.10 lb (45 g).
5.3 Specify the amount of sample, the package sizes, and identification codes to assure a representative sample. A 1-gal (4-L) sample is usually sufficient for the recommended tests but for guidance in selecting a sampling plan consult Recommended Practice E 105.
6. Liquid Paint Properties
6.1 Skinning--Paints containing a binder, that dries by oxidation are subject to skin formation in a partially filled can or by diffusion of air into the can. Since skins are insoluble in the paint, they must be removed before use. This test in a partially filled container indicates the tendency of a paint to skin. Examine the original sample for skins, both on the surface and in its mass. Using a well-mixed, skin-free
portion of the sample, perform a skinning test in accordance with Guide D 154.
No t e 1--A typical minimum time for skinning in accordance with Guide D 154 is 48 h.
6.2 Condition in Container--After storage, paints should be suitable for application with minimum stirring. Charac teristics that are undesirable and objectionable in a stored paint are given in the referenced test method. Determine condition in container in accordance with Method 3011.1 of Federal Test Method Standard No. 141.
6.3 Coarse Particles and Foreign Matter~ Paints must be free of oversize particles and foreign matter to form a uniform film of good appearance. This test, with a 325-mesh (45-|xm) screen, gives the percent of these particles in the paint. Determine coarse particles and foreign matter in accordance with Test Methods D 185.
No t e 2--A typical maximum for coarse particles and foreign matter is 1 weight % of total paint.
6.4 Density or Weight per Gallon--The density of a paint as measured by weight per gallon (or kilograms per litre) provides a check against the theoretical weight calculated from the formula and is useful for determining similarity of two samples. The density is expressed as the weight in pounds of 1 U. S. gal (or kilograms per litre) of the liquid at a specified temperature. A calibrated weight per gallon cup is used. Determine weight per gallon in accordance with Test Method D 1475.
6.5 Fineness ofDispersion--The more finely a pigment is dispersed the more efficiently it is being utilized. One method for measuring degree of dispersion is to draw a paint down a tapered groove in a hardened steel block with the groove varying in depth from 4 to 0 mils ((100 to 0 pm) 0-8 Hegman units). The point at which continuous groupings of particles or agglomerates protrude through the surface of the wet film is taken as the dispersion reading. Higher readings (Hegman units) indicate better dispersion. Determine the fineness of dispersion in accordance with Test Method D 1210.
N' 3--A typical reading for house paint is 60 pm (approximately
2'/2 mils) and for trim paint 25 pm (1 mil). Several arbitrary, scales and modifications of the gage are used by industry. The approximate relationship of these scales to micrometre and mil readings is shown in Test Method D 1210.
6.6 Consistency (Viscosity)--Paints of a given type should fall within a stated consistency range for satisfactory repro duction of a specific formula. While consistency is an important property, it does not determine the quality of a paint and should be used mainly to assure product uni formity. In the referenced method consistency is defined as the load in grams to produce a specified rate of shear. Although the consistency , of most solvent-based house and trim coatings is about 150 to 300 g/100 revolutions, a much wider range is possible because of the wide variations in rheological properties of these paints. Also two. paints of the same consistency may have quite different rheological prop erties. Determine the consistency in accordance with Test Method D 562.
6.7 Dilution Stability--Dilution with a specified thinner shows whether the materials are compatible and whether the reduced paint is stable. The referenced test is a measure of
405
DU P050297586

nk,
"S
IS
D2932
the stability of paint that has been reduced to a desired viscosity, for example, for spray application. The diluent suggested for reduction should be readily incorporated into the paint without excessive stirring or shaking. Determine dilution stability in accordance with Method 4203 of Federal Test Method Standard No. 141.
6.8 Rheological Properties of Non-Newtonian Liquids-- Rheological properties are related to application and flow properties of the liquid coating. The referenced test method covers the determination of the rheological properties of a paint and is particularly suited for use with paints that display thixotropic characteristics. It actually measures vis cosity under varying conditions of time and rotational speed of the spindle. Determine rheological properties in accord ance with Test Methods D 2196.
6.9 Absorption--On porous surfaces, binder penetration can result in pigment volume concentration changes as the film dries. This may cause performance to vary. The referenced method provides a rapid means for measuring the relative penetration of the binder into a porous surface. It provides a rough measure of the wetting and penetrating, quality of liquid materials. Determine the absorption in accordance with Federal Test Method Standard No. 141, Method 4421.
6.10 Flash Point--When the flash point of a material is required for shipping information, use Test Methods D 93, Part B, or D 3278.
7. Paint Application and Film Formation
7.1 Working Properties--Working properties of a paint are generally compared to a standard or described by requirements in the product specification. Test working properties in accordance with Method 4541 of Federal Test Method Standard No. 141.
7.2 Application by Brush--Brushed films should be smooth and free of seeds and on vertical surfaces should show no sagging, streaking, or excessive brush marks. For proper method of application of a brushed film for test purposes, refer to Method 2141.1 of Federal Test Method Standard No. 141.
7.3 Application by Spray--This method covers applica tion of a paint by spray, which is sometimes used for house and trim paint. Refer to Method 2131 of Federal Test Method Standard No. 141.
7.4 Drying Properties--The drying time of a coating is determined by its composition and by atmospheric condi tions during drying. Insufficient, drying may result in dirt or insect pickup resulting in a poor appearance, or a nonuniform appearance caused by dew or rain falling on the paint film. Testing a paint for the required drying properties can determine whether the paint has lost its drying properties through aging or whether insufficient drier was included in the product at the time of manufacture. The specific category, of drying should be selected to suit the types of house paint being tested, since drying times vary widely. Determine the drying time in accordance with Test Methods D 1640.
3. Appearance of Dry Paint Film
8.1 Color Difference of Opaque Materials, Visual Evalua tion of-- Visual comparison is fast and often acceptable although numerical values are not obtained. The referenced
practice covers the spectral, photometric, and geometry characteristics of light source, illuminating and viewing conditions, sizes of specimens, and general procedures to bj used in the visual evaluation of color differences of opaque materials. Determine the color difference in accordance with Practice D 1729.
8.2 Color Difference of Opaque Materials, Instrument Evaluation of--Color difference between a product and the standard can be tested by instrument. Generally the toler, ance is agreed upon between the purchaser and the seller and may also be required if a product specification h involved. Determine the color difference in accordance with Method D 2244.
8.3 Directional Reflectance--This property is a measure of light reflected from the surface of the paint. It usually is assigned a value in specifications for white and pastel shades. Determine daylight directional reflectance in accordance with Test Method E 97.
8.4 Gloss _ (60-deg Specular)--Determine the specular gloss in accordance with Test Method D 523. Oil house paints are typically in a gloss range from 30 to 70, while trim enamels are in a gloss range from 70 to 90.
8.5 Hiding Power (Dry Opacity)--Hiding power is the measure of the ability of a paint to hide the substrate. It is, however, dependent upon uniform film thickness which is influenced by the flow and leveling. Test Method D 344 is a practical test in which paint is applied with, a brush, film thickness is approximately measured, opacity is evaluated visually as compared to a standard paint, and results sire affected by flow and leveling application properties of the paint Test Method D 2805 is considered to be a more precise and accurate test that does not need a riiaterial paint standard. Paint is applied with an applicator bar to minimize the effects of flow and leveling, film thickness is rigorously measured, and opacity is instrumentally evaluated. Deter mine hiding power in accordance with Test Methods D 344 or D 2805.
9. Properties of Dry Paint Film
9.1 Elongation (Flexibility)--Elongation is a measure of flexibility of a paint film. Generally, gloss house paints and trim paints will have no problem in passing a mandrel bend test. Flat house paints, however, may fail a sharp bend. Determine elongation in accordance with Test Methods D 1737 dr D 522.
9.2 Moisture Blister Resistance--Blister resistance is re lated to the ability of a dry paint film to resist the formation of blisters caused by water from the wood substrate. The watercan come from either the interior of the home or from structural defects that permit entry of the water behind the wood. Moisture blister resistance can be qualitatively evalu: ated in a laboratory test. Determine resistance to moisture blistering in accordance with Test Method D2366.
9.3 Fume Resistance--Fume resistance is the ability of a dry paint film to resist discoloration in a moist hydrogen sulfide atmosphere. This type of atmosphere may be present near industrial or other polluted areas and can cause paint to yellow or darken in as little time as overnight exposure. There are no ASTM or Federal test methods for evaluating1 this property, but one procedure used by the industry is as follows:

Standard Test Method for Pressure Mottling and Blocking Resistance of Organic Coatings on Metal Substrates1
This standard is issued under the fixed designation D 3003; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
I. Scope 1.1 This method covers determination of the pressure
mottling and sticking, or blocking resistance of organic coatings applied to coil-coated or factory-coated metal prior to postformed.
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
2, Summary of Method
2.1 The coated metal is cut into suitably sized panels. A stack of these panels is then subjected to a specified pressure and temperature for a specified time to permit any pressure mottling and sticking or blocking to develop. The heating elements of the test apparatus are turned off and, after cooling, the specimens are examined for any signs ofsticking or blocking, and mottling. The results are rated on the 0 to 10 scale and may be used in accepting or rejecting the coating according to standards established by the purchaser and the seller.
3. Description of Terms
3.1 pressure mottling--film distortion or uneven pattern giving a change of gloss and nonuniform appearance. It is usually caused by pressures within a painted coil or stacked painted sheets or other painted products.
3.2 blocking or sticking--the condition wherein coated surfaces adhere to each other.
4. Apparatus2
4.1 A suitable hydraulic or mechanical press or vise may be used. The equipment shall be capable of producing the required test pressure in pounds-force per square inch (or kilopascals) and be equipped with a suitable device for : measuring the force applied.
i 1 This method is under the jurisdiction of ASTM Committee D-l on Paint and i Related Coatings and Materials and is the direct responsibility of Subcommittee
D0I.53 on Factory-Precoated Strip Metai. Edition effective Dec. 22, 1971. 2 Suitable equipment includes Pasadena or Studebaker Hydraulic Presses;
Gardner Laboratories Cam-activated Pressure Mottling Tester; and drill press vises modified for use with a torque wrench if agreed between purchaser and seller f (Hensley, W. L., "Pressure Mottling Test," Journal ofPaint Technology, Vol 40, : No. 517, February 1968, p. 54/1).
5. Test Specimens and Conditions
5.1 At least four, and preferably six, flat panels shall be cut from the coated stock, die age of which shall be within the limits agreed upon by the purchaser and the seller.
5.2 Panels should be at least 4 by 2.5 in. (100 by 70 mm) to provide an adequate area for assessing the results. Where the equipment does not provide adequate pressure, smaller panels may be used. The minimum recommended size is 2 by 2 in. (50 by 50 mm).
5.3 Use only flat panels. If necessary, file the edges smooth to ensure maximum contact between the surfaces. When the equipment permits, panels larger than the pressure plates may be used, thus eliminating any effect from uneven edges. With this method, the pounds-force per square inch (or kilopascals) is calculated using only the panel area within the pressure plates.
5.4 The film thickness of the coating under test shall be as specified or agreed upon by the purchaser and the seller.
5.5 The coated stock shall be tested under the conditions of pressure, temperature, and time mutually agreed upon by the purchaser and the seller. Pressures ranging from 110 to 350 psi (750 to 2400 kPa), temperatures from 110 to HOT (43 to 60C), and times of 2 to 16 h have been used.
5.6 In the absence of agreed or specified test conditions, a pressure of 110 5 psi (750 35 kPa), a temperature of 110 3F (43 1.5C), and a time of 16 h shall be used.
5.7 The total force applied is measured by a suitable gage and the pounds-force per square inch (or kilopascals) is calculated by dividing the force (pounds-force or newtons) by the area in square inches (or square millimetres) of one side of one panel.
6. Procedure
6.1 Stack the panels face to back as used in production with both face and back coatings applied. Limit the number of panels in the test to the quantity that can be heated rapidly to and maintained at the correct panel temperature throughout the test.
6.2 For presses having heating units, place the test panels in the press and bring the heating platens in contact but with light pressure. Turn on the electrical heating unit, and heat the panels to the required test temperature. When this temperature is reached, the indicating light will shut off. Apply the required pressure and maintain it for the specified time (6.4).
6.3 Where the apparatus does not have built-in heating units, preheat the mechanical press or vise. Place the panels in the press at room temperature with very light contact and heat the unit in an oven to the required temperature. Then

6.4 Record the time only after the specified temperature and pressure are reached. Check the temperature and pres sure at intervals during the test.
6.5 At the end of the specified time, turn off the heat and allow the panels to cool to room temperature under pressure before removal and separation.
6.6 After removal from the press, grade the panels sepa rately for both sticking or blocking and mottling in accord ance with Table 1. In assessing the results ignore effects due to sharp or uneven edges.
6.7 Maintain panels that are to be reaccessed after a recovery period at 75 5F (24 3C).
6.8 For both properties assign each coating a grade which is the arithmetic mean of all panels tested.
7. Report
7.1 Report the following data for each coating: 7.1.1 Equipment used, 7.1.2 Number of panels tested, 7.1.3 Pressure, 7.1.4 Temperature and heating process (built-in or oven), 7.1.5 Time,
7.1.6 Grade for sticking or blocking, and 7.1.7 Grade for mottling.
8. Precision
8.1 In an interlaboratory test of this method, two opera tors in each of seven laboratories tested two different coatings, subjected to two treatments (pressure, temperature, and duration) and rated them for sticking, and pressure mottling. The within-laboratory and between laboratory pooled standard deviations were found to be as follows:
Rating Parameter
Pooled Standard Deviations Within-
Laboratory
Between Laboratory
S PM Average
0.42 1.10 0.38 1.06 0.40 1.08
Based on these results the following criteria should be used in judging the acceptability of results at the 95 % confidence level.
8.1.1 Repeatability--Two results, each the mean of the two sets of panels, obtained by the same operator should be considered suspect if they differ by more than 1 to 2 units.
8.1.2 Reproducibility--Two results, each the mean of two sets of panels, obtained by operators in different laboratories should be considered suspect if they differ by more than 3.7 units.

5. Selection of Staining Agents for Testing Stain Resistance of Coatings
5.1 The producer and the user shall select staining agents from the reagents in Section 4. Selection of staining agents should depend on end use, such as wall, ceiling, horizontal surface, or floor.
5.2 In the absence of agreement between the producer and the user, the suggested staining reagents for each intended use are indicated in Section 4 by V, H and L.
5.3 It is not necessary that all finishes pass all tests.
6. Test Specimen
6.1 Test panels shall be of regular production finish. 6.2 If regular production finished panels are not available, the producer and the user shall agree upon the following variables: face veneer or wood surface, filler or filler stain, primer coat, topcoat, and dry film thickness for each coating material.
7. Panel Conditioning
7.1 Before testing, panels must be aged for a time and by a method agreed upon between the producer and the user.
8. Procedure
8.1 Conduct the test with panel surfaces horizontal at room temperature unless a different temperature is specified.
8.2 Place 0.5 mL of each staining agent on the finish surface and allow to stand uncovered for 18 h (or a time agreeable to the producer and the user) except for staining agents 4.3 to 4.6. On these put a 1-in. (25-mm) square of double-acid-washed quantitative filter paper. The purpose of the filter paper is to maintain a longer wet contact of volatile reagents with the surface of the finish.
8.3 After 18 h exposure, or other time period agreed to b the producer and the user, wash the surface with water, rjn2
with ethanol (1+1) and dry with a paper towel. Place a, panel in a vertical position with a diffuse tight source aJj view (Note) from a distance of 2 to 3 ft (0,6 to 0.9 Examine the surface for graying, spotting, wrinkling, discoj' oration, or other film defects and report.
N' --This method of viewing panels gives the best correlation of
staining damage between laboratories. However, the following inform3, tion should be noted: U) When viewing panels across the grain at a lo angle that is being varied, many more stains will appear viable than would appear visible perpendicular to the surface. These additional stains are superficial stains only. (2) When viewing with and against % grain, there appears to be an even greater number of superficial stains than would appear when viewing perpendicular to the surface or across the grain.
9. Interpretation of Results
9.1 Each product finish differs greatly in stain resistance requirements. The key, in general, is that the resistance to staining must be adequate for that finish's end use when first used in place and throughout the expected life span of the specific product
9.2 The end use choice of resistance to staining should be agreed upon between the producer and the user.
10. Precision
10.1 Agreement between laboratories by visual compar ison varied according to how samples were viewed.
10.1.1 Stains viewed perpendicular with a diffused light source at a distance of 2 to 3 ft (0.6 to 0.9 m) for graying, spotting, wrinkling, discoloration, or other film defects gave, complete agreement between laboratories.
10.1.2 The same test stains viewed both with and across the grain at a low angle resulted in many more superficial stains being evident, depending upon the eyesight and judgment of the observer.

4 Conditions Affecting House Paint Topcoats
4.1 Practical requirements and performance of latex Douse paint may vary with:
4.1.1 Substrate type, such as type and quality of wood or j^rdboard, grain of wood, knots, pitch, etc., type and quality pf masonry, ratio of cement to aggregate, alkalinity, etc.
4.1.2 Substrate weathering. Weathering of wood before painting will probably adversely affect the performance. Some weathering of masonry surfaces before painting may pave beneficial effects on the performance.
4.1.3 The type, quality, and suitability of primer, under coat, conditioner, etc., used under the topcoat and the time between coats.
4.1.4 Environmental conditions such as temperature at die time of application and during drying. As these paints contain water as a thinner, surfaces do not have to be completely dry before application. However, low tempera ture during drying may cause poor film formation.
4.1.5 Contaminants on the surface of the substrates. 4.1.6 Condition of previously painted substrates such as degree of chalk, adhesion of film, dirt, mold, general condition of substrate paint.
5. Sampling
5.1 Prior to sampling, the condition of the container should be established since damage to it may cause evapora tion, skinning, or other undersirable effects in the coating. Determine the condition of the paint in accordance with 6.1 and 6.2.
5.2 Sample in accordance with Practice D 3925. Deter mine the weight per gallon in accordance with Test Method D 1475. Repeat this procedure until successive values agree within 0.1 lb (45 g) or as agreed upon between the purchaser and the seller. Samples for testing may then be taken.
5.3 Specify the amount of sample, the package sizes, and identification codes to assure a representative sample. A 1-gal (4-L) sample is usually sufficient for the recommended tests, but for guidance in selecting a sampling plan, consult Practice E 105.
6. Liquid Paint Properties
6.1 Condition in Container--Thickening, settling, and separation are undesirable and objectionable if a paint cannot be reconditioned and made suitable for application with a reasonable amount of stirring. The referenced method covers procedures for determining changes in properties of paints after storage. Determine the condition in the con tainer in accordance with Method 3011 of Federal Test Method Standard No. 141.
6.2 Coarse Particles and Foreign Matter--Paints must be : free of coarse particles to form uniform films of good
appearance, a typical maximum being 1 weight % of total paint. The specified test with a No. 325 (45-p.m) sieve gives ; the percent of these particles in a paint. Determine coarse i particles and foreign matter in accordance with Test Method j D 185. i 6.3 Density or Weight per Gallon--The density as meai sured by weight in pounds per gallon or kilograms per litre is \ used to assure product uniformity from batch to batch. In the referenced method the density is expressed as the weight i in pounds of 1 U.S. gal (kg/L) of the paint at a specified
temperature. Determine the density in accordance with Test Method D 1475.
6.4 Nonvolatile--The amount of nonvolatile in a coating is not necessarily an indication of performance. It is, however, useful for determining similarity of two samples. Determine nonvolatile solids in accordance with Test Method D 2369.
6.5 Fineness ofDispersion--The more finely a pigment is dispersed, the more efficiently it is being used. One method for measuring the degree of dispersion (commonly referred to as "fineness of grind") is to draw the material down a calibrated, tapered groove in a hardened steel block with the groove varying in depth from 4 to 0 mils (100 to 0 jim) and calibrated Hegman 0-8. The point at which continuous groupings of particles or agglomerates, or both, are visible through the surface of the liquid is taken as the fineness reading. Lower readings in mils or micrometres or higher readings in Hegman units indicate better fineness of disper sion. Determine fineness of dispersion in accordance with Test Method D 1210.
N' --The fast drying of latex paints makes it difficult to make
accurate measurements of this type. Low-gloss paints do not generally require dispersion finer than a 1 to 2 Hegman reading.
6.6 pH--Latex paints with low (acidic) pH may corrode the container. Changes in pH during storage may indicate poor stability of a latex paint. Determine pH in accordance with Test Method E 70.
6.7 Consistency--Paints of a given type should fall within a stated consistency range for satisfactory reproduction of a specific formula. In the referenced method, consistency is defined as the load in grams required to produce a specified rate of shear. Although the consistency of most latex paints is about 150 to 300 g/100 revolutions, a much wider range is possible because ofthe wide variations in rheological proper ties of these paints. Also two paints of the same consistency may have quite different rheological properties. Determine the consistency of the product in accordance with Test Method D 562.
6.8 Rheological Properties of Non-Newtonian Liquids-- Rheological properties are related to application and leveling properties of the liquid paint. The referenced methods cover the determination of rheological properties and are particu larly suited for use with paints that display thixotropic characteristics. They actually measure viscosity under dif ferent shear rates. Determine rheological properties in accor dance with Test Methods D 2196 or D 4287, or both.
6.9 Freeze-Thaw Stability--Water-based paints may be subjected to freezing conditions during shipping and storage. Suitably stabilized paints will resist several cycles of freezing and thawing without showing deleterious changes such as coagulation, graininess, or excessive viscosity increase. Many latex paints will increase in viscosity but can still be considered satisfactory if other properties which may be affected by a higher viscosity such as leveling and brushability are satisfactory. Determine the extent of change in several properties in accordance with Test Method D 2243.
6.10 Microorganism Resistance--Bacteria in a latex paint can cause gassing, putrefactive or fermentative odors, and loss of viscosity. Determine if the paint contains living
417
DUP050297598
# D 3129"
bacteria and if it is resistant to attack by bacteria in accordance with Test Method D 2574.
7. Paint Application and Film Formation
7.1 Drying Properties--Under average conditions most flat latex paints are dry-to-touch in 1 to 2 h when the water has evaporated from the film. Slow drying of the film may result in dust pickup, poor appearance and, when used on an exterior surface, rain or dew may cause a nonuniform appearance. They can usually be recoated from within a few hours to 18 h. Curing to obtain the ultimate properties may take only a few days for some latex paints, while others may require 1 to 2 weeks depending on composition. Determine drying time in accordance with Test Methods D 1640.
7.2 Producing Films of Uniform Thickness--Methods D 823 covers the preparation of coating films of uniform thickness essential in conducting tests.
7.3 Application Properties--Application properties of a paint are generally compared to a standard or described by requirements in the product specification. Determine appli cation properties in accordance with Method 4541 of U.S. Federal Standard No. 141.
7.3.1 Brush Application--For proper method of applica tion of a brushed film for test purposes refer to Method 2141 of U.S. Federal Test Method Standard No. 141.
7.3.2 Spray Application--House and trim paints are sometimes applied by spray. Determine the spray application properties in accordance with Method 2131 of U.S. Federal Test Method Standard No. 141.
7.4 Touch-Up Uniformity--After a paint has dried, areas where less material was applied sometimes become notice able, If the paint has suitable touch-up properties, additional material can be applied to these areas only, instead of. refinishing the complete wall. The color, gloss, and leveling, of the touched-up areas and the previously coated area should be uniform. Differences in these properties are often caused by short wet-edge time, poor leveling on recoat, and pigment orientation or flotation during and after application. Determine touch-up properties in accordance with Test Method D 3928.
8. Appearance of Dry Paint Film
8.1 Color Differences by Visual Comparison--Visual comparison of color is fast and often acceptable although numerical values are not obtained. The referenced method covers the spectral, photometric, and geometric characteris tics of light source, illuminating and viewing conditions, sizes of specimens, and general procedures to be used in the visual evaluation of color differences of opaque materials. Deter mine color fence in accordance with Practice D 1729.
8.2 Color Differences Using Instrumental Measure ments--The differences in color between a product and its standard can be measured by instrument. Generally, the tolerance is agreed upon by the purchaser and the seller and may also be required if a product specification is involved. Color instruments provide numerical values that can be compared to subsequent measurements. The referenced method covers the instrumental determination of small color differences, observable. in daylight illumination, between nonfluorescent, nonmetameric, opaque surfaces such as paint specimens. If metamerism is suspected, visual evalua
tion (8.1) should be used to verify the results. Calculate j5 accordance with Test Method D 2244 the color difference that have been measured instrumentally.
8.3 Directional Reflectance--This property is a measure of the appearance of lightness of a coating. It is usually assigned a value in specifications for white and pastel shadJ a typical minimum reflectance being 86 % for white wall paint. In the referenced method, the direction of illuming, tion and viewing is specified so as to eliminate the effect of gloss. Determine daylight directional reflectance in accor. dance with Test Method E 97.
8.4 Gloss 60--Gloss level can affect dirt pickup and washability. Exterior latex house paints and trim paints may vary in gloss. A typical range would be from 5 to 60 units. Determine the specular gloss in accordance with Test Method D 523.
8.5 Hiding Power (Dry Opacity)--Hiding power is the measure of the ability of a paint to hide the substrate. It is, however, dependent upon uniform film thickness which is influenced by flow and leveling. Test Method D 344 is a practical test in which paint is applied with a brush, fil thickness is approximately measured, opacity is evaluated visually as compared to a standard paint, and results are affected by flow and leveling application properties of the paint. Test Method D 2805 is considered to be a more precise and accurate test that does not need a material paint standard. Paint is applied with an applicator bar to minimize the effects of flow and leveling film thickness is rigorously measured, and opacity is instrumentally evaluated. Deter mine hiding power in accordance with Test Method D 344 or D 2805,
9. Properties of Dry Paint Film
9.1 Flexibility--Elongation is a measure of flexibility of a paint film. Generally house paints will have no problem in; passing a mandrel bend test. Most latex paints can be bent over a `A-in. (6.4-mm) mandrel without affecting the film. Determine elongation in accordance with Test Method D 522.
9.2 Moisture Blister Resistance--Moisture blister resis tance is a necessary property ofa house and trim paint. It can be evaluated by an accelerated laboratory test. Determine resistance to moisture blistering in accordance with Practice D 4585.
9/3 Fume Resistance--Fume- resistance is the ability of a dry paint film to resist -discoloration in a moist hydrogensulfide atmosphere. This type of atmosphere may be present near industrial areas and can cause paint to yellow or darken in as little'time as'.overnight exposure. There are no applicable ASTM or Federal test; methods for fume resis tance, but one method used in industry is as follows:
9.3.1 Apply a sufficient number of coats of the paint to two glass plates to hide the surface completely, allow to dry for 6 h, and expose one ofthe plates in a moist atmosphere of hydrogen sulfide for 18 h. Compare the color with the unexposed plate. The exposed plate should be no darker than the unexposed one.
9.4 Exterior Exposure Resistance--In conducting exteriorexposures, refer to Practice D 1006.

This is jspecially true in warm, moist climates. Determine mildew jjsistance using Practice D 3456. 94.8 Stain Resistance--There is neither an ASTM' nor a federal test method available for evaluating stain resistance 0f exterior latex paints. There are, of course, different kinds 0f stain such as the water-soluble extractives in w6od substrates, the formation of lead or mercury sulfides, and top-down from metal surfaces of oxides that stain. Different lands of test methods are required for the various stains. 9.4.9 Efflorescence Resistance--Exterior latex paints can contain sufficient solid water-soluble material to cause a noticeable deposit on the film through leaching by water and subsequent evaporation. Determine the tendency of the paint to effloresce in accordance with Test Method D 1736. 9.4.10 Fade Resistance--Exterior latex paints usually bsve good color retention because of their good chalk resistance. However, the use of improper latex, pigment volume concentration, or pigments can lead to fading. There are no applicable ASTM or Federal test methods for fade 1 resistance. One method on the evaluation of chalk-fade has been published in the literature.9 9.4. L1 Dirt Pickup--Low-gloss exterior latex paints gener ally have good resistance to dirt pickup. Gloss hr semigloss latex paints may be more subject to this type of disfigure ment. Exterior exposure particularly under an .overhang wiD

indicate a paint's tendency for this property in a relatively short time (about 1 year). Determine degree of dirt collection in accordance with Test Method D 3719.
9.4.12 Adhesion to Chalky Surfaces--Latex paints gener ally have little ability to penetrate porous substrates. There fore they do not adhere well to chalky substrates unless they are modified with some liquid that does penetrate and can bind a layer of chalk. (However certain latices do exist that are designed to adhere well to chalky surfaces. These could be considered without the need for a modifying liquid.) There are no directly applicable ASTM or Federal test methods for adhesion to chalky substrates. The industry generally uses a pressure-sensitive tape for testing this prop erty. The tape is pressed firmly onto the dried latex film (fresh dry films do not adhere as well as aged dry films) and then removed rapidly by pulling back upon itself. Method 6301 of U.S. Federal Test Method Standard No. 141 describes a similar method but includes water exposure.
9.4.13. Wet Adhesion--Determine the wet adhesion of exterior latex paints in accordance with Method 6301 of U.S. Federal Standard Test Method No. 141.
10. Analysis of Paint
10.1 Chemical Analysis--If a specification requires cer tain raw materials or certain components in a given amount, then chemical analysis is required to determine whether the specified materials are present, and in what amounts. Anal ysis does not necessarily establish paint quality that can be also greatly affected by manufacturing techniques. Most ASTM analytical methods apply to solvent-reducible coat ings. However, some of these ( 9 be adapted for analysis of water-reducible paints.
10.2 Volatile Content--The percent of volatile matter indicates the thinner loss from the film as it dries. This quantity subtracted from 100 % gives the nonvolatile con tent Determine the volatile content in accordance with Test Method D 2369.
10.3 Pigment Analysis--The analysis of pigment may be required ifthe product is covered by a specification, or if it is agreed between the purchaser and the seller. Analyze the pigment in accordance with selected test procedures from Methods D 215.

1. Scope
1.1 This test method covers the quantitative determina tion of the content of cellulose nitrate (also known as nitrocellulose) in lacquers containing alkyd resins.
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Test Method
3.1 The method of standard additions is employed. Incre ments of cellulose nitrate, in solution, are added to aliquots of the sample. Absorbance measurements are made of the band at 848 cm-1 (11.8 pm) for each addition. The original content is then calculated from absorbance versus concentra tion.
4. Significance and Use
4.1 Coating compositions based on a mixture of synthetic resins and cellulose nitrate dissolved in organic solvents are quantitatively analyzed for the cellulosic derivative without isolating it. The test method is applicable to lacquers for which the grade of nitrocellulose is known and available. Other cellulosics, alkyd resins, many vinyl resins, and solvents do not interfere. Components, such as acrylic resins
and some vinyl polymers, that absorb infrared near 848 cm-1 (11.8 pm) interfere with the determination. High boiling ester solvents, in particular methyl cellosolve acetate, may also interfere with the determination if not removed in the evaporation procedure (see 8.3).
5. Apparatus
5.1 Infrared Spectrophotometer, automatic recording, double-beam. Most infrared spectrophotometers operate from 4000 to 650 cm-1 (2.5 to 15 pm), but in this test method only the range between 1000 and 750 cm-1 (10 to 14 pm) is used. See Practices E 168.
5.2 Absorption Cells, sealed, with sodium chloride (NaG) windows, 0.1-mm path length, one pair approximately matched.
5.3 Film Vacuum Evaporator, rotary thin or equivalent apparatus, to obtain redissolvable lacquer solids without decomposition of the cellulose nitrate.
5.4 Oven, vacuum drying, thermostatically controlled to operate at 65 + 2 C.
6. Reagents
6.1 Purity ofReagents--Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chem ical Society, where such specifications are available.4 Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening >the accuracy of the determination.

8.5 Infrared Analysis: 8.5.1 Schedule the operating parameters of the infrared spectrometer to attain highly accurate absorbance values (refer to the directions of the manufacturer of the instru ment). To accomplish this, set for lengthier scanning time and high signal-to-noise ratio, in accordance with Practice E275. 8.5.2 Place one cell, containing DMA, in the reference beam. Place the other cell, filled in turn, with each of the solutions (Note 2), in the sample beam. Record the spectrum between 1000 and 750 cm-1 (10 and 14 pm) three times for each solution. Rinse the cell with DMA, and purge with dry nitrogen gas after each solution has been examined. No t e 2--To facilitate the transfer of the solutions to the cell, a small glass syringe fitted with a 3-in. (75-mm) hypodermic needle may be used.
8.5.3 Measure the difference in absorbance, AA, between

the maximum absorbance at 848 cm-1 (11.8 pm) and the minimum at 813 cm-1 (12.3 pm). Determine the mean AA for the three runs on each solution.
9. Calculation
9.1 Plot the absorbance difference, A>4, versus the cellu lose nitrate additions and extrapolate the curve to zero absorbance. The intersection of the curve with the abscissa (concentration axis) gives the original cellulose nitrate con tent in the diluted sample. See Fig. 1.
9.2 Alternative Method--Solve for C in the three simulta neous equations derived from the expression for the BeerBourguer law, A = abc
A/lo/( C + 0.0) = AAoa/{ C + 0.1) = AA01/( C + 0.2)
where: C = original concentration of cellulose nitrate, in grams per
25 mL and the subscripts for AA correspond to the amounts of cellulose nitrate added in grams per 25 mL. Calculate the mean of C. 9.3 Calculate the weight percent of cellulose nitrate E in the original lacquer as follows:
E = {CxDx 100)fS
where: D = dilution factor, S - weight of specimen, and C = grams of cellulose nitrate in 25 mL.
9.4 Calculate weight percent cellulose nitrate E in nonvol atile portion of original lacquer as follows:
E = (C x 5 x 100 x 100)/(S x N)
where: N -- nonvolatile content (see 8.2).
10. Precision
10.1 On the basis of a study in which four laboratories analyzed two different samples for percent of cellulose nitrate relative to the total samples, T, and relative to the nonvolatile matter, NVM, the within and between labora tory standard deviations were found to be:

i. Terminology
3.1 Definitions--For definitions of terms, refer to Defini tions D 16.
4. Summary of Practice
4.1 The vehicle is extracted from the dried paint and after filtering is cast on a salt plate. The infrared spectrum is obtained and compared with reference spectra for identifica tion of major components.
4.2 The paint is applied to a filament and pyrolyzed to depolymerize the vehicle. An internal standard is added and the pyrolyzate is separated into its components by gas-liquid chromatography. Monomers are identified by comparison of relative retention times.
5. Significance and Use
5.1 Identification of specific acrylic polymers in emulsion paints is often difficult or impossible by infrared alone. This

is particularly true when the acrylic is present in a small amount as a comonomer with vinyl acetate, or when blended with alkyds or other ester systems. If identification of an acrylic component is required in such a system, it may often be accomplished by gas-liquid chromatographic analysis of the pyrolyzed paint film. The presence of a number of other polymers may often also be confirmed by pyrolysis since they produce characteristic and reproducible pyrograms.
5.2 The pyrograms obtained from unknown samples vary in complexity according to the sample composition. It is necessary to establish the presence or absence of as many components as possible from a study of the infrared spectra obtained in the first part of this practice. The gas-liquid chromatography results may then be used to help identify any unknown components present and to confirm identifi cations made by infrared.
6. Interferences
6.1 Dibutyl maleate and dibutyl fumarate monomers are not successfully recovered by this procedure. If their presence is suspected as comonomer in a vinyl acetate copolymer system, n-butyl alcohol should be found in the pyrolyzate. This evidence, together with the absence of butyl acrylate or butyl methacrylate monomer peaks, is an indirect indication of the presence of one or both of these monomers.
6.2 The presence of relatively low quantities of copo lymerized adds may not be successfully established by this procedure, due to some unavoidable decomposition of acrylate and methacrylate esters to acrylic or methacrylic add and the corresponding alcohols during the pyrolysis. The infrared spectrum and an acid number determination, both run on the polymer solids, may usually be relied upon to establish the presence or absence of acid groups in the polymer.
6.3 In the case where the polymer being analyzed is simple (such as a vinyl acetate-alkyl ester copolymer, or a single acrylate-methacrylate copolymer), it might be advan tageous to examine the total pyrolyzate directly by infrared (as a solution in carbon disulfide).
7. Apparatus
7.1 Spectrophotometer, recording, double-beam, infrared, with a range from at least 2.5 pm to 15 pm and a spectral resolution of at least 0.04 pm over that range. For checking the performance of the infrared spectrophotometer, see Practice E 275.

Decant off the solvent and discard.
No t e 2--If there is an interest in characterizing the water-insoluble petroleum ether-soluble fraction, it should also be filtered through fine-texture paper, taken to dryness, and examined by infrared.
9.5 Add 10 mL of the extraction solvent mixture (8.3) and place on a steam bath or low-temperature hotplate for approximately 1 h. Filter, while still hot, through a finetexture filter paper. Ifthe polymer solution is viscous, it may be diluted further with extraction solvent mixture and warmed prior to filtration. Alternatively, the pigment may be removed from the polymer solution by centrifuging. Evaporate the solution on the steam bath or hotplate to a volume of 1 mL or less.
9.6 Place the concentrated polymer solution on a halide salt crystal and spread to form a uniform film. The thickness of the film should be such that when the infrared spectrum is recorded, the transmittance of the strongest band fells between 5 and 15 %.

N' 3--If the infrared spectrum obtained in 9.8 shows poly(vinyI
acetate) or poly(vinyl chloride) to be present, the pyrolysis step should be modified to prevent the acetic or hydrochloric acid formed from grading other monomers that may be present in the pyrolyzate. Addition of a drop of concentrated ammonium hydroxide to the vial just prior to pyrolysis, neutralizes the acid as it is formed. The pyrolyzate
then be recovered by dissolving in diethyl ether just before
sampling.
10.4 Tightly screw the coated filament-cap assembly onto the glass vial and connect the filament leads to the power
supply10.5 Submerge the entire vial m liquid nitrogen contained
in a small Dewar flask. Allow to equilibrate for several ojinutes, then apply a predetermined current for approxi mately 10 to 15 min.
N' 4--The optimum temperature which varies for different
polymer types may be determined experimentally from known polymer systems. Six amperes (approximately 600C) has been found to be close to optimum for the types tested. A study of the pyrolysis of acrylic polymers showed that heating times varying from 10 to 30 min produced no significant differences in the composition ofthe pyrolyzate.
10.6 Turn off the power supply and allow the filament to cool for several minutes. Remove the vial from the liquid nitrogen and substitute a standard screw cap for the filament-
cap. 10.7 Using a syringe, add n-butyl acetate to the pyrolyzate
equal to approximately 20% of the pyrolyzate volume. 10.8 Install the silicone resin column in the chromato
graph and allow it to condition to 200C. Set up the following conditions on the chromatograph:
Temperatures, C Injection port Detector block Column (programmed):
Initial Final AT, "C/min
Carrier gas: Flow rate, mL/min
Detector current, mA
270 270
70 200 6 helium 60 150
10.9 Inject 5 pL of pyrolyzate into the chromatograph, engage the chart drive, and start the temperature pro grammer. Attenuate as necessary during the run.
N' 5--The use of the method described minimizes the tendency
of pyrolysis products to undergo secondary reactions while still in the vapor state. This simplifies the chromatograms obtained, making interpretation easier.

4 Relative retention times listed are meant to serve as a guide for identification purposes. It should be understood, however, that the numbers listed are not absolute, and will vary somewhat from laboratory to laboratory and from instrument to instrument. For maximum accuracy in making identifications from retention time data, each analyst should prepare his own table by running the monomers of interest under the same conditions used for the analysis of the pyrolyzate.
10.10 Calculate retention times relative to the n-butyl acetate internal standard peak for each major peak obtained. Compare relative retention times obtained with known values for monomers of interest (see Table 1).
10.11 If any doubt remains concerning an identification based on the pyrogram obtained, it is recommended that the peak of interest be trapped as it is eluted from the chromato graph for subsequent positive identification by infrared spectroscopy or mass spectrometry.
10.12 Bum off any remaining organic residue by applying 8 or 9 A for a few seconds. Disconnect the filament from the power supply; then clean off any adhering pigment by gently
brushing with a test tube brush while holding the filament under running water. The same filament may be reused
many times.

3. Summary of Test Method
3.1 Standardized road gravel is projected by means of a controlled air blast at the coated specimens. Generally the test conditions are made more severe by performing the test at low ambient temperatures. The resultant chipping effect is evaluated by comparison with a set of photographic stand ards that appear in the Pictorial Standards Coating Defects,
4. Significance and Use
4.1 Chipping of coatings, particularly on the leading faces
and edges ofautomobile surfaces, is considered unacceptable
by owners. In formulating a coating or coating system to-
meet service requirements, the resistance to chipping damage
by flying objects such as gravel is one of the properties of
importance since it can vary considerably as other properties,
are adjusted. Since, resistance to chipping decreases at lower
temperatures partly as the result of decreased flexibility, the
test may be more directly related to service conditions by
performing it at a low temperature., This test method is
designed to produce a controlled amount of impact by the
media on. the tcoated panel in order to enhance reproduc
ibility.'

3.1 The test paint is applied to a nonporous surface, air dried, then measured for reflectance. A special colored penetrating medium is applied, the excess removed in a specified manner, and reflectance measured again. The difference between the two readings indicates the degree of porosity; the smaller the difference, the lower the porosity of the film and the greater its ability to resist penetration.

1. Scope
1.1 This practice is intended to serve as a guide in measuring with infrared instruments the temperature during, the curing process of coatings applied to wood products.

designed with a narrow or broad band pass and may compensate for changes in ambient temperatures. One instrument3 with the latter feature has a band pass of 8 to 14 I pm. Another instrument4 that must be rezeroed to compen. sate for changes in ambient temperatures has a band pass of 3 to 20 pm. However, this instrument can be completely portable and requires essentially no warm up time.
3.3 Thermalvoltaic Type5--These instruments are equipped with collection chambers for radiated energy that then heat a thermocouple to the temperature of the surface
2. Significance and Use
2.1 The forest products finishing industry has encoun tered difficulties in measuring the temperature of painted surfaces during the curing process. The use of thermocouples is not entirely satisfactory because the thermocouple wires tend to conduct heat away too rapidly from the area where the temperature is being measured. Infrared radiation ther mometers that are simple to operate can circumvent this difficulty. After calibration they are aimed at the surface,
measured. As such, they require a minimum target area off in. (25 mm) in diameter and have a delay time that averages about 1.5 s.
3.4 Instrumentation is available for on-line process monitoring control of product temperatures. These units have long term stability that permits operation in varying ambients encountered in plants or mills without periodic calibration. The instruments also have output signals to operate recorders and controllers.

6. Test Panels
6.1 Panels of extruded aluminum alloy No. 6063-T5 with dimensions 6 by 3 by `A in. (150 by 75 by 6.3 mm) shall be used for the test.
7. Procedure
7.1 Preparation of Test Panels: 7.1.1 Buff the aluminum panels and remove the buffing compound with an organic solvent. 7.1.2 Immerse the panels in cleaning solution (5.2) for 1 h at a temperature of 200F (93C). 7.1.3 Rinse the panels in tap water having a pH of 6.5 to 7.5 until the surface is free of water break. Use reagent water for rinsing if the pH of the tap water is outside the specified limits. The panels shall be free from evidence of corrosion or surface attack. 7.1.4 Immerse the panels in neutralizing solution (5.4) at 75 2F (24 l'C) for 30 s to neutralize any retained alkalinity and to promote adhesion of the applied coatings. 7.1.5 Rinse the panels in reagent water and allow them to dry a minimum of 1 h before coating. 7.2 Coating of Test Panels: 7.2.1 Apply the coatings being evaluated to the test panels in a uniform continuous film by automatic spray equipment \ in accordance with Method A of Test Method D 823. 7.2.2 For the mortar test, spray two panels on one side with two or more full wet coats to produce a minimum dry | film thickness of0.6 mils (15 pm) and two panels with one or ; more full wet coats to produce a minimum dry film thickness of 0.3 mils (7.5 pm). 7.2.3 For the acid test, spray two panels with two or more full wet coats, on both sides, to produce a minimum dry film < thickness of 0.6 mils (15 pm) and two panels with one or more full wet coats on both sides to a minimum dry film thickness of 0.3 mils (7.5 pm). 7.2.4 Allow the panels to dry for 7 days at 73 3.5F (23 2C) and 50 5 % relative humidity. 7.3 Mortar Test: 7.3.1 Prepare freshly mixed mortar by dry mixing 75 g of building lime (5.3) and 225 g of sand (5.5) and adding sufficient reagent water while stirring to make a soft paste that can be formed into a firm mortar patty approximately 1 y% in. (40 mm) in diameter and lA in. (6 mm) thick.

7.3.2 Apply the mortar to the top and bottom areas of the
test panels and, without drying, immediately expose them for 7 days at 95 to 98 % relative humidity at a temperature of 70 * 3.5F (21 2C) in an automatically controlled cabinet.
7.3.3 At the end of 7 days take the panels from the test cabinet and immediately dislodge the mortar patties from jjje panels using a damp cloth to remove any residue.
7.3.4 View the surface of the panels perpendicular to the sUrface under a diffused light source providing a minimum jjght intensity at the surface of 200 ft-candles (2150 lx). Examine for blistering, peeling, lifting, crazing, flaking, or ^coloration of the coating, and for corrosion of the coated part of the aluminum panel. Three observers shall evaluate each panel and the majority assessment shall govern.
7.4 Acid Test: 7.4.1 Apply a mixture of 50 parts beeswax and 50 parts
paraffin to protect the raw edges to a distance of 3A in. (10 mm).
7.4.2 Immerse the panels, in the acid bath (5.1) at 70 3.5F (21 2C) for 6 h. Remove the panels, rinse in water, and allow to dry.
7.4.3 Examine and evaluate as in 7.3.4.
8. Precision
8.1 The effect of acid and mortar on the coatings is expressed in terms of appearance and numerical values are not generally assigned.
8.2 In a cooperative test program, consistent results were obtained by all cooperators when all of the test variables were controlled closely. The success of the procedure depends particularly on having a continuous film of the coating on the panels, the proper pH value when rinsing the panels, and proper protection of the edges of the panels in the acid test.

2.1 ASTM Standard: D 3271 Practice for Direct Injection of Solvent-Reducible
Paints into a Gas Chromatograph for Solvent Analysis2 3
3. Summary of Practice
3.1 The sample of whole paint with added tricresyl phosphate is heated by means of a silicone oil bath. The distillation is allowed to proceed for a period of time and then vacuum is applied. Finally dry air is passed through the system to facilitate the removal of any high-boiling solvents present.
5. Reagents '
5.1 Methylene Chloride or Acetone. 5.2 Silicone Oil.5 5.3 Tricresyl Phosphate.
\
6. Procedure
6.1 Immerse the receiver in a bath containing dry ice with methylene chloride or acetone of sufficient depth that the liquid reaches to the bottom level of the rubber stopper.
6.2 Pour approximately 15 g of the whole paint sample into the 50-mL distillation flask. Immediately follow with 10 mL of tricresyl phosphate and without delay mix the contents of the flask.
6.3 Assemble the apparatus and close the needle valve and stopcock attached to the capillary tubing. Immerse the distillation flask by raising a silicone oil bath preheated to 155 to 160C (Warning--see Note 1) until it reaches the side arm (Note 2). Allow the distillation to proceed for 15 min without vacuum.
j ! \
f
I s
No t e l: Warning--Care should be taken to prevent the temperature of the silicone oil exceeding 160'C because of possible formation of explosive mixtures of air and solvents from the sample being analyzed.
No t e 2--The liquid level in the oil bath should be as high, as is practical.
| i ?
4. Apparatus
4.1 Apparatus5 is shown in Fig. 1. It is essential in assembling this apparatus, that the volume of the portion preceding the flask be kept to a minimum by using diameters of connections and distances as small as possible. Include a gage in the assembly for measuring pressure.

5. Reagents and Materials
5.1 Soil--A good quality greenhouse-grade potting soil, suitable for plant propagation, containing 25 % peat moss. PH of the soil should fall from 5.5 to 7.6. Do not allow soil to become compacted.
5.2 Cultures:
6. Preparation of Apparatus
6.1 Place greenhouse soil in the tray in the cabinet and add water to the tank chamber to the desired depth. Allow the cabinet to equilibrate for 24 h before inoculating the soil with the specified mold suspensions.
6.2 Prepare mold slants of all three cultures and age 10 to 14 days or purchase prepared mold slants8 of all three cultures. Prepare mold suspensions from each type of mold slant by the following procedure: Add one drop of 25 % nonionic surfactant9 solution to 95 to 100 mL sterile deionized or distilled water and shake. Pipet 5 mL of this solution onto the mold slant. Scrub the surface of the slant with a sterile cotton swab to remove as much spore and mycelial growth as possible without digging up the surface of the agar. Pour the water from the scrubbed slant back into the surfactant-sterile water mixture for dilution. Shake gently for 15 to 20 min to break up clumps of mold. Use a pipet to distribute the mold suspensions evenly over the surface of the greenhouse soil in the tray in the cabinet.
6.3 Allow two weeks of continuous operation for the mold to sporulate and equilibrate with the environment before starting a test. It should not be necessary to recontaminate continually the chamber of panels after sufficient microor ganism growth has built up in the soil, if the chamber is maintained in continuous operation.
6.4 Viability of the mold growth in the cabinet can be checked by placing several malt agar or potato dextrose agar plates,10 open and face up, at several locations on the panel support rods. After 1 h, cover plates and place in incubator at 90 2F (32.5 1C) for 3 days. If an incubator is not available, leave the covered plates in the cabinet. Mold
8 Suitable cultures can be obtained from American Type Culture Collection, 12301 Parklawn Dr., Rockville, MD 20852. Cultures can be maintained on malt agar or potato dextrose agar. Prepared slants can be obtained from Difco Laboratories, Inc., Detroit, Ml 48232; Baltimore Biological Laboratories, Baltimore, MD 21218 or from equivalent sources.

It is 1 the responsibility of the user of this standard to establish I appropriate safety and health practices and determine the I applicability ofregulatory limitations prior to use.
I 2. Significance and Use
[ 2.1 The growth of fungi and algae in and on the surface of paint films represents a major cause of discoloration or disfigurement of painted surfaces. Because of their dark pigmentation, it is frequently difficult to distinguish fungi and algae from soil or dirt particles. The use of magnification of as much as lOOx affords easy distinguishability among fungal spores, fungal mycelia, algae, and dirt and is recom mended in cases where such difficulty is apparent.
3. Types of Fungal and Algal Growth
3.1 Two types of fungal growth may be observed: 3.1.1 Spores--Spherical bodies, gray black in color, ob served singly or in clusters. May or may not be associated with fungal mycelia. Spores are the reproductive form of fungi. Spores of Pullularia pullulans magnified lOOx are shown in Fig. 1. 3.1.2 Hyphae--Thread or filament structures, gray to black in color, that make up the mycelium or vegetative form of fungi. Hyphae may appear alone or with spores attached. Hyphae of Pullularia pullulans, magnified 50x are shown in Fig. 2. 3.2 Amorphous growth typical of an alga such as Chlorococcum Sp. appears in Fig. 3 at a magnification of 39x. Terrestrial algae can appear green to dark brown in color.

5.2 The photographic standards illustrated in Fig. 5 rate the disfigurement of paint films from 0 to 8. A rating of 10 would indicate a film totally absent of disfigurement by particulate matter.
6. Procedure
6.1 Compare each specimen with the photographic stand ards associated with this test method to determine which most closely matches the degree of disfigurement on the specimen. When the degree is intermediate between two adjacent standards select the intermediate odd number as the disfigurement rating.
6.2 The density of fungal or algal growth as well as dirt

accumulation may vary over the painted surface being evaluated. This variation may be the result of the location of the surface (that is, under an eave of a house versus an
exposed area), nonuniformity of the substrate, film thickness or other factors. Such variation should be noted when
reporting the rating assigned to specimen under test. In examining test specimens for fungal, algal, or dirt disfig urement, the possibility of failure due to the wood substrate should be recognized and reported.
6.3 When microbial disfigurement is detected (or estab lished), distinguish between algal and fungal growth. For the latter, estimate whether spores or mycelia predominate.

3. Significance and Use
3.1 This guide is intended as a reference for those con cerned with the inspection of industrial coating work. A punch list for use in the field is included as an appendix. Many of the details covered may be in a specification for a particular project. A specification for coating projects should

include the coatings to be used. The various items are explained in detail in the appendix.
4. Preparation for Inspection
4.1 The guide describes the duties of the inspector and discusses inspection methods, both visual and instrumental, that can be used to determine that the specification require ments have been met by the painting contractor.
4.2 Before painting is started the project engineer must provide the inspector with information from the official plans and specifications as to coating type, thinner to be used, mixing ratios to be used, recommended application thickness, recommended primer, tie coat, topcoat, time between coats, surface preparation, method of application, and any special precautions to be followed such as limits on ambient conditions. These details should be recorded in an inspector's record book to eliminate any misunderstanding between the inspector and the contractor.
5. Field and Shop Inspection
5.1 Surface Preparation is one of the most important factors affecting the performance of coatings. The specifier should determine the proper level in accordance with the expected service life and type of coating specified.
5.1.1 Pictorial Standard D 2200 (SSPC-Vis 1) should be provided to the inspector on a job involving painting of structural steel. The standard is used by the inspector to determine whether the degree of surface preparation speci fied in a contract has been attained by the contractor. For large jobs it is recommended that before work starts, an actual steel sample of adequate size be blasted to the satisfaction of the project engineer. This blasted surface should be protected by a clear acrylic coating or encased in plastic and used for reference purposes as the work progresses.
5.2 Factors Affecting Coating Performance--There are a number of factors that must be considered to ensure a proper painting job.
5.2.1 Cleanliness--Many materials if not removed from the surface will affect the life of the coating. These include oil, grease, soil, weld spatter, and slag that make it impossible to obtain proper adhesion to the metal surface. Deposits of salts (such as chlorides and sulfates) must be removed or long-term coating performance will be seriously affected. The Steel Structures Painting Council (SSPC) issues detailed surface preparation specifications that cover methods for solvent cleaning and hand and power tool cleaning as well as the various methods of blast cleaning.
5.2.2 Mill Scale, the bluish-black oxide resulting from the hot-rolling process, is a constant source of trouble leading to coating failure. This scale is very hard and can crack or loosen from temperature changes both in fabricating and weathering in the field.
5.2.3 Surface Profile--The texture of the metal surface has a significant effect on the performance of coatings since it increases the surface area to which the coating can develop adhesion. In fact, the term "anchor pattern" is sometimes used to describe the depth of profile required. This varies both with the type and size of the abrasive used. Coarser abrasives generally produce a coarser and deeper profile. Deep profiles are advantageous for adhesion but require

DU P050297628
# D 3276
l
more coating to fill in the valleys and cover the peaks of the profile; they cannot be used with low-build coatings that do not cover the peaks even when several coats are applied. A general recommendation is that the surface profile should be one quarter to one third of the dry film thickness of the coating system but does not apply in every case if the resulting profile would be too great. .
5.3 Cleaning Procedures--Safety precautions are not ad dressed separately for each of the following cleaning methods. Each has its own safety-related hazards, and U.S. Occupational Health and Safety Administration regulations should be followed. Material Safety Data sheets (MSDS) for the solvents and cleaning compounds provided by the manufacturer should also be consulted for proper worker
protection. 5.3.1 Chemical Cleaning--Solvents are used to remove
oil, grease, and related materials. The solvent is applied to the surface by wiping or scrubbing with rags or brushes. The contaminants must be removed (not simply spread out) by a thorough wiping of the affected areas with cloths saturated with clean solvent. Contaminated cloths must not be dipped into clean solvent. The cleaning should be repeated with clean rags and fresh clean solvent. Emulsions, cleaning compounds, steam cleaning, or similar methods and mate rials may also be used. Where emulsion cleaners, soaps, or detergents are used, they must be removed completely by washing with clean hot water. SSPC SP-1 covers cleaning
procedures using these materials. 5.3.1.1 Solvent Vapor Cleaning is a procedure that can be
adapted to a production line or a piecework operation. Vapor cleaning removes all soluble contaminants but does not disturb the natural oxide film. If this film must be removed, mechanical cleaning will be necessary as well. The part to be cleaned is placed in the saturated vapor above the heated solvent so that the solvent vapor condenses on the metal surface. Vapor degreasing does not remove particulate matter and parts must be wiped to remove any insoluble; soils. Vapor degreasing has the advantage over solvent wiping in that hot solvents .are used and the solvent condensation removes soils without recontamination.
5.3.2 Hand Tool Cleaning is the method used for the removal of loose mill scale, loose rust, loose or otherwise defective coating, weld flux, slag and spatter from metal surfaces by hand brushing, hand sanding, hand chipping or scraping using wire, fiber, or bristle brushes, sandpaper, steei wool, hand scrapers or chisels, and chipping hammers. The surface is then cleaned to the condition St 2 given in Method D 2200 (SSPC-Vis 1). SSPC also provides a detailed specifi cation, SSPC-SP 2.
5.3.2.1 Hand tool cleaning requires that all tar, oil and grease, weld flux, and other greasy contaminants be removed

Unlove abrasive from pockets and comers. 11 j 3.4.6 Blast cleaned surfaces should be further treated,
,ijned or painted as specified on the same day they are pasted, preferably within 8 h, or in any event before any
yjsjble rerusting occurs. Reblasting will be necessary on any (iicface if rust bloom forms before the coating can be applied.
5,4 Cleaning and Preparation of Various Surfaces-- Before application of any coating, all surfaces to be coated pjst be thoroughly cleaned and properly prepared to the j^quirements of the specification. All dust, dirt, oil, grease, jjoisture, soot, tars, or other contaminants should be re moved from unpainted surfaces. Previously painted surfaces jjjould be similarly cleaned of all foreign matter; all deteriomted coating must be removed as well. Mortar or cement (jrippings from earlier repairs must be removed by mechan ic or chemical means. Tree limbs or other growth ob
structing the structure should be cut away to provide ready
access. 5.4.1 Steel Surfaces--Removal of rust and scale must be
done in the manner and to the degree specified, that is, hand, power tool, or blast cleaned.
5.4.1.1 On bridges, all dirt and debris must be cleaned Jem around bearing plates, shoes, and other components. The entire surface of the beam or truss seat on each unit of
the structure should be cleaned. On truss spans particular attention should be paid to removal of dirt and debris from pockets and crevices. Open steel grid-type decking should be cleaned by use of a detergent steam-water-type jet that will clean painted surfaces without softening or removing tightly adhering coating. The machine manufacturer's recom mended solution should be used. Surfaces should then be nosed with a clear water jet.
5.4.2 Galvanized Surfaces that are to be painted should be cleaned and treated in accordance with Method A or D of Practices D 2092. Alternatively, the surface may be allowed to weather a minimum of 6 months before cleaning and painting.
5.4.3 Aluminum Surfaces: 5.4.3.1 Complete removal of oil and grease and, for unanodized aluminum, treatment is essential. Vapor degreasing or immersion in an alkaline or acid cleaning solution are commonly used in shop work. In the field a water wash followed by solvent cleaning is a good starting point. 5.4.3.2 Vinyl wash primer is one of the metal pretreatments commonly used on unanodized aluminum. The material is described in Practices D 1730, Type B, Method 8 and is covered by SSPC Paint 27. For exterior work an inhibitive primer is required over this pretreatment, head pigmented primers should never be used over alu minum surfaces. The minimum treatment for aluminum is Type B, Method 3 of Practices D 1730, which describes the use of an alcoholic phosphoric acid cleaner. 5.4.4 Precautions in Preparing Unpainted and Previously ^dinted Surfaces--Cleaning should proceed by sections, tays, or other readily identifiable parts of the work. The 'leaning of each section, bay, or part of the work must be
entirely completed, inspected, and accepted before any
coating is applied. The system of alternately cleaning and painting short sections by one workman is not good practice.
5.4.4.1 If, in the opinion of the project engineer, traffic, or any other source produces an objectionable amount of dust, it is customary for the contractor, at his own expense, to control the dust by using tarpaulins, etc., for a sufficient distance around the structure and take any other precaution necessary to prevent dust and dirt from coming into contact with the cleaned or freshly painted surfaces. It may some times be necessary between the various coats to clean newly coated surfaces using some of the specified methods.
5.4.4.2 Some areas to be painted or repainted are exposed to chemical fumes and should be washed with water before painting. Washing may also be necessary between coats of paint. If there is reason to suspect the presence of chemicals, the surfaces should be tested before applying subsequent paints.
5.4.4.5 Residual contaminants present on pitted steel can be a problem. Chloride from deicing salts or a marine environment and sulfate contamination from air pollution have recently been recognized as one of the main factors in premature breakdown of coating systems. High-pressure water blasting is often used to remove these contaminants.
5.5 Inspection ofSurfaces Prior to Field Painting: 5.5.1 New Construction--It must be emphasized that the first coat should be applied to the cleaned surfaces before any soiling or deterioration can occur. If painting is done out of
doors, the cleaned areas should receive the first protective coat well before nightfall brings lower temperatures and possible moisture condensation on the surfaces. When sur face preparation and painting are carried on indoors, over night delays between cleaning and painting may be permis sible except on blast-cleaned surfaces.
5.5.1.1 Shop-coated steel that has been shipped to the erection site should be stored on blocks to prevent contact with the ground and where it is least likely to be marred, scratched, or subjected to harmful contamination by grease, oil, salts, etc. Insofar as practicable, the steel should be stored to avoid the formation of waterholding pockets. If outdoor storage lasts for several months, the inspector should check the integrity of the coating from time to time, and have any deficiencies corrected. Correction of these deficiencies may require complete blast cleaning and repriming in the field if the shop primer has weathered so long as to make touch up too extensive. The length of time between shop priming and erection and subsequent topcoating should be kept to a minimum to avoid the problem of intercoat adhesion.
5.5.1.2 Immediately before applying the first field coat, the shop-coated surfaces should be cleaned of dust. If
necessary to remove grime and oil substances, they are wiped with solvents selected so as not to soften the film appreciably. Miscellaneous scratches and breaks in the shop coat, in cluding those occasioned by field welds, bolts, or rivets, should be cleaned and touched-up as specified before the steel receives the first overall field coat
5.5.1.3 The inspector must ensure that field rivets have been cleaned of slag and weld spatter. It is important that every coat of the system be applied over dry, soil-free surfaces, and that all previous coats be free of mechanical damage. Great care should be exercised to prevent trapping
449
DUP0502 97630

corrosive salts under or between coats. 5.5.1.4 The inspector should determine whether the spec
ifications are being followed with reference to the painting or prohibition of painting of contact surface's in bolted or riveted surfaces of construction. He must ensure that sur faces not in contact but that will be made inaccessible by assembly or erection, have received the full number of specified coats before they become inaccessible.
5.5.2 Maintenance Repainting--In most cases, mainte nance painting will consist of spot-cleaning and priming of small isolated areas of deterioration followed by application of one overall new finish coat to all surfaces of the structure. The inspector of maintenance painting must be alert for several conditions not encountered in the painting of new work.
5.5.2.1 Sound coating not intended to be removed should not be damaged by cleaning operations on adjacent areas. This is particularly important with spot-blast cleaning.
5.5.2.2 The junctions between sound coating and spotcleaned areas should present a smooth, feathered appear ance. The application of coating to spot-cleaned areas should overlap the old, adjacent coating to a slight extent in order to assure full coverage of the cleaned areas. Before the overall finish coat is applied, the inspector must ensure that oil, grime, dust, and other contaminants are cleaned from the old coating surfaces.
5.5.2.3 Before work has progressed too far, adhesion of the newly applied coat to the old coating should be carefully checked. Under the direction of the engineer the inspector may explore beneath the surface of the existing or new coating film for covered-over rust or loosening of the old film, and where he discovers such conditions, require that the surface be cleaned and repainted.
5.5.2.4 The effect of any newly applied coating on the old underlying coating should be noted. Any coating that shows curling, lifting, or excessive wrinkling should be reported to the engineer immediately since it may have to be removed and the area repainted. If the defects are general, rather than existing in a few isolated areas, use of a different type of coating may be necessary.
6. Inspection Equipment
6.1 General--Visual observation is the most important part of inspecting coating application. There are, however, instruments and mechanical aids that are of considerable help to the inspector. They make the painter aware that his work can be checked during progress and even after comple tion. The different instruments that can be used are de scribed in this section.
6.1.1 Surface Profile Gages--The inspector can determine the surface profile of blast-cleaned steel substrates using Test Methods D 4417 to assure an adequate "tooth" is obtained for the specified material. Some of the common instruments are:
6.1.1.1 Surface profile comparator9 for visual compari sons of the profile against a reference disk for sand, grit, and shot blast-cleaned steel.
6.1.1.2 Depth micrometers with conical points to project into the valleys to determine profile depth.
6.1.1.3 Tape,10 to create an exact replica of the profile on a special material. The tape is measured in the field using a spring micrometer to determine average maximum profile height.
6.1.2 Adhesion of Existing Coating--The inspector should carry a pocket knife that can be used to determine the soundness of existing paint where there might be blistering or underfilm corrosion. This is a subjective test and its value depends upon the inspector's experience. The cross-cut test, Methods D 3359, is more reproducible.
6.1.3 Portable Pull-offAdhesion Testers are available. The apparatus measures the force required to remove a metal stud that has been cemented to the coated surface as described in Method D 4541.
6.2 Field Inspection Equipment in good working order should be available to the inspector so that he may perform his function properly.
6.2.1 Drying and Curing Times--These are both imporfant considerations since drying time and curing time can
both be affected. Minimum temperatures are required for reactive and water-borne coatings while too high a tempera ture can make application difficult. Inorganic zinc-rich primers and moisture-cure urethanes require certain min imum humidity conditions for proper cure. The manufactur er's recommendations must be followed.
6.2.1.1 Thermometers--The paint inspector may need several types of thermometers and should have at least an accurate pocket thermometer with a range from about 0 to 150F (--18 to 65C) for measuring the ambient air temper ature. The same thermometer or a floating dairy thermom eter may be used to determine the temperature of liquid coating, solvent, etc. The pocket thermometer may also be used for determining the temperature of metal surfaces by placing it against the metal while shielding the outer (away from the metal) side of the bulb by means of putty or similar material, so that the reading is not affected by the ambient temperature. Flat surface-temperature thermometers are also available for this purpose.
6.2.1.2 Dew Point--A psychrometer containing a wetand dry-bulb thermometer for determining relative humidity and dew point is a useful inspection tool. Hand-held sling or electrical types are available as well as a direct reading digital type.
6.2.2 Coating Consistency is an important characteristic since durability is related to film thickness and whether a film of the proper thickness can be applied is partly controlled by consistency.
6.2.2.1 Consistency Cups--There are occasions, such as on-site thinning, when it is necessary to check paint consis tency during field application. While giving only partial information about the viscosity of a coating, the Zahn cup is a portable device for checking quickly the approximate consistency of coatings and other liquids. It consists of a bullet-shaped, stainless steel cup with an orifice in the bottom. Attached to the cup is a looped handle with a small

A relatively inexpensive balance having a sensitivity of 0.1 g provides sufficient accuracy. The differ ence between the full and empty weights divided by 10 is the weight in pounds of 1 gal of the paint. Complete instructions for the procedure are given in Test Method D 1475.
6.2.4 Wet-Film Thickness Gages--This type of instru ment is designed to measure the thickness of a wet film of paint immediately after it is applied to a surface. Note that erroneous readings may result when using the gage on fast-drying paints such as inorganic zinc. If a wet-film gage is used to determine the thickness of coats subsequent to the first, great care must be taken that partially hardened undercoats are not indented by the gage, thus giving high readings. If the coat being measured has an appreciable softening effect on the previous coat, a wet-film gage cannot be used with accuracy. It is very important to record test results and send a copy to the engineer.
6.2.4.1 Interchemical Gage--This instrument is rolled over the newly applied wet film on a smooth flat portion of the surface and the thickness read directly in mils (micrometres). Complete details are given in Method A of Methods D 1212.
6.2A.2 Notched Gage--This device has a series of cali brated steps for measuring thin to heavy coats. The gage with
nondestructive methods for wood or other nonmetallic substrates. All of the different types require calibration with standards the thickness of which is known and in the same range as the coating to be measured. The calibration must be made on metal of the same kind, temper, thickness, and contour as that beneath the coating. Test Methods D 1186 and 1400 describe procedures. Measurements on relatively rough surfaces, such as a surface blasted to a high profile, may be misleading unless the instrument is calibrated on an identical surface.
6.2.6.1 Magnetic-Type Gages'1--Use either an electro magnet requiring a power supply or a permanent magnet. The principle of the method is that a nonmagnetic coating changes the magnetic force between the magnet and the magnetic base or the magnetic flux between the poles of the magnet. As the change is a function of distance from the metal, the gage can be made to read film thickness directly. Magnetic gages may be affected by the mass of the steel, or if electric welding is being carried out on a structure, for example, a ship's hull, at the time of measurement. Test Methods D 1186 describe the procedure for using magnetic gages. The method is also described in SSPC-PA 2 which includes instructions on the number of measurements for different areas and tolerances on the required film thickness.
6.2.6.2 Nondestructive procedures based on inductance and eddy current techniques are described in Test Method D 1400.
the proper face is placed squarely on the fresh, wet film. It is
then withdrawn perpendicularly without a sliding movement. 7. Coating Storage and Handling
The true wet-film thickness lies between the highest step coated and the next highest which was not coated. The procedure is described in Practice D 4414.
6.2.5 Dry-Film Thickness Gages--Dry-film thickness measurements are of great importance because the protec tion of the substrate is directly related to the thickness of the ! coating. There are two ways of making the measurements,
i nondestructive^ or destructively. The latter involves pene-
7.1 Storage of Coating and Thinner--All coatings and thinners should be stored in areas or structures that are well-ventilated and not subject to excessive heat, open flames, electrical discharge, or direct rays of the sun. Storage should be in compliance with applicable regulations. Mate rials susceptible to damage at low temperatures must be stored in heated areas. If a coating is stocked for a consider-
; bating or cutting through the film to the substrate with a
needle or blade and measuring by some means the distance between the top and..bottom of the film. Because the dimensions are so small, some cuts are made at an angle in an attempt to increase the accuracy of the measurement.

able length of time (several months), it is desirable to invert the containers at monthly intervals. This will prevent hard settling and thus make mixing quicker and easier when the coating is to be used.
7.1.1 Coating containers should remain unopened until needed and the oldest should be used first. The manufactur er's written instructions should be followed regarding shelf life. Coatings that have livered, gelled, or otherwise deterio rated during storage should not be used. If a particular material is in question, do not use it until it has been tested by the manufacturer or independent laboratory and found to be satisfactory.
7.1.2 Where a skin has formed in the container, the skin should be cut loose from the sides of the container, removed and discarded. If it is felt that the skins are thick enough to have a practical effect on the composition, the remaining paint should not be used until it has been tested and found to be satisfactory.
7.2 Mixing ofCoatings--All coatings must be thoroughly and completely mixed in clean containers before use. Where there is noticeable settling and mixing is done either by power stirrers or by hand, most of the vehicle should be poured off into a clean container. The pigment is then lifted from the bottom of the container with a clean broad, flat paddle, lumps broken up and the pigment thoroughly mixed with the vehicle present. The poured-off vehicle should be returned slowly to the original container with simultaneous stirring. It is also useful at this point to mix or pour repeatedly from one container to another (boxing) until the composition is uniform. The bottom of the original con tainer should be inspected for unmixed pigment. The coating should not be mixed or kept in suspension by means of an air stream bubbling under the coating surface.
7.2.1 Some coatings may require straining after mixing to ensure homogeneity and to remove skins and foreign matter. The strainers should be of a type to remove only skins, etc., but not to remove pigment. For example, a 150-mesh (105-pm) strainer is normally satisfactory for most coatings unless some specific size is required in the specification.
Coatings should not remain in buckets, spray pots, etc., overnight, but be gathered into a container and remixed before use, provided the manufacturer's stated pot life will not be exceeded. Containers must be covered when not in use, to reduce volatile losses and skinning.
7.2.2 Coatings should be agitated enough during applica tion to ensure homogeneity. Some materials may even require constant agitation during use.
7.3 Thinning--Some specifications permit field thinning of laboratory-accepted coatings while others do not. This section describes some commonly accepted procedures when thinning is permitted.
7.3.1 Initial Samples--When thinning on the job site is permitted and unless other arrangements have been made, (for example using manufacturer-supplied thinner from unopened containers and complying with manufacturer's written thinning instructions), the painting inspector may need to submit to an agreed-upon testing laboratory a 1-qt (1-L) sample from each batch to be thinned, together with a 1-qt sample of the thinner to be used using clean sample containers in both cases. With these samples a request is submitted for advice on the proper thinning rate for the
conditions prevailing and the consistency limits of . thinned coating.
7.3.2 Thinning ofCoating--Ml additions ofthinner mu,. be made in the presence of the inspector and no othe amounts or types of thinner than those permitted by tj specification or manufacturer, or both, may be added Thinning is carried out by pouring about half of th thoroughly mixed coating into an empty, clean container The required thinner is then added and the two portions are boxed to obtain a homogeneous mixture.
7.3.3 Sampling of Thinned Coating--During the work additional samples need not be submitted for testing unless a deviation is noted in the coating consistency or if it suspected that there has been a change in the thinner.
7.3.3.1 When an inspector is qualified and has the necessary equipment available at the field office, arrangements may be made for on-site inspection of thinning and of the thinned coating. This speeds acceptance of a coating and lightens the laboratory workload. The inspector must keep a record of all paint modifications, amount of thinning, weight per gallon, and viscosity. Where dry-film thickness is speci fied, the inspector must calculate the new wet thickness necessary to obtain the desired dried thickness with the thinned coating. He should make frequent checks ofwet-filtu
thickness as work progresses, however compliance with the specification should be based on dry-film thickness where possible.
7.3.3.2 To determine the wet-film thickness of the thinned coating required to obtain the specified dried-film thickness, the percent volume of nonvolatile (solids) in the original coating must be known. This figure is readily obtained from the manufacturer. With this information the calculation may be made as follows:
!
W= D (1.0 T)/S where: W - wet-film thickness, D = desired dry-film thickness, S - percent by volume of coating solids, and T = percent by volume of thinner added.
7.4 Heating of Coating--Coatings as delivered in the manufacturer's containers and mixed thoroughly, are ready for use, unless the specification permits on-site thinning of high-viscosity material. Should the coating temperature be low, that is, 50F (10'C) its consistency may increase to the point where application is difficult. Where thinning is not permitted, the coating may be heated. Should the contractor wish to reduce the viscosity by heating to make application easier, the containers may be warmed in hot water, on steam radiators, or by other acceptable indirect heating processes, In-line heaters are also available for application equipment. Direct application of flame to the containers is forbidden by fire regulations. It should be noted, however, that heating of the coating alone will not compensate for ambient or surface temperatures, or both, that are below the minimum specified for that material.

without adverse effects. Within the limitations of the composition of the coating, this may be satisfactory de luding upon the type ofcoating and providing the surface is

failure of the coating. g.3 High Temperature--The maximum reasonable sur
face temperature for application is 125F (50Q. A surface djat is hot may cause the coating solvents to evaporate so fast that application is difficult, blistering takes place, or a porous gm results. To keep the temperature down it is desirable, where practical, to paint under cover at a shop or to protect the surfaces from the sun with tarpaulins.
g.4 Moisture--Painting should not be undertaken in rain, snow, fog, or mist, or when the temperature of the metal surface is below the dewpoint. This is especially true in the spring and fall when days are warm and nights are cool. Wet surfaces should not be painted unless the coatings are specifically designed for that condition. Relative humidity is usually a good index of the acceptability of air conditions and specifications often contain an 85 % upper limit. If it is suspected that the temperature and humidity conditions are such that moisture is condensing upon the surface, the inspector may make the following test: Use a psychrometer to determine the actual relative humidity and dew point; compare the dew point with the metal temperature measured with a surface temperature thermometer. It is generally accepted that the surface temperature should be at least 5F (3C) higher than the dew point. A less accurate test is to lightly moisten a small area with a damp cloth and observe. evaporation and drying; if the dampness decreases and evaporates within 15 min, the surface is considered satisfac tory for the application of coating from the standpoint of dampness and condensation at that particular time. 8.4.1 When coatings must be applied in damp or cold weather, the substrate should be painted under cover, or protected from the surrounding air, and the steel heated to a satisfactory temperature. The steel should remain under cover until dry or until weather conditions permit its exposure in the open. 8.4.2 Applied coatings exposed to freezing, excessive hu midity, rain, snow, or condensation should be permitted to dry. Damaged areas of coating should then be removed, the surface again prepared and painted with the same number of coats of the same kind as the undamaged area. 8.5 Wind--The wind direction and velocity must be considered when applying coatings in areas where airborne overspray could damage automobiles, boats, and structures nearby. Heavy winds result in considerable loss of coating and in excessive drying of the droplets reaching the surfaee: This results in an inability of the film to flow together and create a continuous barrier free of "holidays." Such condi-
tions can also create excessive amounts ofdry spray that can interfere with adhesion of the applied or subsequent coats. These problems can be avoided by utilizing brush or roller application methods instead of spray, or scheduling the work at the less windy times of day, changing materials to the dry-fog types that do not adhere or damage adjacent prop erty, scheduling the work so that if dry spray becomes attached to adjacent components it will not create a quality problem because it is attached to the final coat.
9. Coating Application
9.1 Residual Contaminants--Visually inspect the surface immediately prior to painting to ensure that spent abrasive, dust, and debris have been completely removed. Dust removal shall be considered satisfactory when the path left by a gloved hand wiped over the surface is barely discernible when viewed from a distance of 3 ft (l m). During this inspection, also ensure that any oil or grease contamination that may have become deposited on the surface is completely removed. This is accomplished by solvent cleaning in accordance with SSPC-SP1.
9.2 Quality Assurance--The inspector must ensure that: (1) coatings received at the fabricators or in the field meet the description of the products acceptable under the require ments of the specification; (2) they are properly mixed and thinned (where allowed); (3) colors match a visual standard provided that proper precautions have been taken to prevent damage to adjacent areas from cleaning and painting opera tions; (4) working practices are so scheduled that damage to newly applied coating is minimized; (5) application equip ment (brushes, spray) is acceptable for type, cleanliness, and usability; (6) weather conditions are acceptable under the requirements of the specification; (7) field-testing equipment on hand is in satisfactory working order ready for use; and (8) only the methods of application permitted under the specification are used and that their use is in accordance with 9.2.1 and 9.3 through 9.7. SSPC-PA1 is a specification for application of coating.
9.2.1 Film Defects--All coats should have nearly smooth, streamlined surfaces relatively free of dryspray, overspray, orange peel, fish eyes, pinholes, craters, bubbles, or other significant defects. Show through, insufficient hiding skips, and misses are not acceptable. Runs and sags should be brushed out during application. Abrasive, dirt, or other debris that becomes embedded in the paint film should be removed prior to the application of subsequent coats.
9.3 Brush Application--Painting by brush must be done in a neat, workmanlike manner to produce a smooth coat as uniform in thickness as possible. Coating should be worked into all irregularities in the surface, crevices, and comers. Runs, sags, or curtains should be brushed out. Surfaces that are inaccessible for painting with brushes and on which spraying is not permitted should have coating applied by means of sheepskin daubers. To provide adequate film thickness on places prone to premature breakdown, it is recommended that edges and comers ofall metal work, rivet heads, bolts and nuts, and all individual members, bars, shapes, and plates should be striped by brush painting in advance of the application ofcoating to other parts.
9.3.1 Brashes must be ofgood quality with pliable bristles. They should not exceed 4 in. (100 mm) in width and the
453
DUP0502 97634
D 3276
bristle length should be no less than 3'/2 in. (90 mm). When
not in use, the brushes should be kept in a clean, acceptable condition. The inspector may prohibit the use of any brush not in an acceptable condition.
9.4 Spray Application--Spray application may or may not be allowed. Often it is acceptable in fabricating shops but, because of the possibility of damaging surrounding property or coating films from overspray, it may not be permitted in the field. The inspector should be familiar with the different kinds of spraying, which are compressed air spray, airless spray, hot spray, and hot airless spray.
9.4.1 The equipment should be suitable for the intended purpose, capable of properly atomizing the coating to be applied, and be equipped with suitable pressure regulators and gages. The equipment must be kept in a suitably clean condition to permit proper coating application without depositing dirt, dried coating, and other foreign materials in the film. The air supply for conventional and hot spray application should be free of moisture or oil. Airless spray equipment should be properly grounded. Any solvents left in the equipment should be completely removed before ap plying coating to the surface being painted.
9.4.2 Coating ingredients must be kept properly mixed in spray pots or containers during coating application, either by continuous mechanical agitation or by intermittent agita tion. Coating should be applied in a uniform layer, with overlapping at the edge of the spray pattern. The spray pattern should be adjusted so that the coating is deposited uniformly. During application the gun should be held at right angles (perpendicular) to the surface (not arced or fanned) and at a distance that will ensure that a wet layer of coating is deposited on the surface. The trigger of the gun should be released at the end of each stroke. Poor spray technique resulting in excessive overspray (or sand-like finish) should not be tolerated. All runs, sags, or curtains must be brushed out immediately or the coating will have to be removed and these areas repainted.
9.4.3 Usually brush striping of edges and other vulnerable locations as described in 9.3 is required. Brush or sheepskin daubers are used to coat all areas inaccessible to the spray gun and brushes and are used to work coating into cracks, crevices, and blind spots not adequately spray painted.
9.4.4 Particular care should be observed with respect to type and amount of thinner, coating temperature, and operating techniques in order to avoid depositing coating that is too viscous, too dry, or too thin when it reaches the surface.
9.5 Roller Application--Rollers that are clean and of a material not soluble in the coating to be applied should be used. Rolle- 'overs are available in a variety of diameters, lengths, typ of fabric, and fiber lengths. The nap (length) used on metal surfaces generally varies from l/t to % in. (25 to 75 mm). The longer fibers hold more coating but do not provide as smooth a finish. Therefore their use is generally restricted to rougher surfaces and faster drying coatings. There are also specialized rollers available for use on pipes, fences, and even pressure rollers that continually feed the coating to the roller cover.
9.5.1 The roller cover should be dipped into the coating until it is saturated and then rolled along the tray ramp until the coating is completely wetted in. The first load of coating
on the roller should be applied to scrap material to force.

cratering by entrapped air. Application should be finish^ with light perpendicular strokes in one direction (usual]!

9.6 Miscellaneous Methods--Methods such as mitts, and squeegees or trowels are used for special^
products or in situations where the conventional methods
are not suitable due to the location or configuration of the work.
9.6.1 Painter's pads generally consist of a roller-type
synthetic fabric attached to a foam pad. The size is generally 4 by 7 in. (100 by 175 mm) and the fiber length is 3/i in. (5
mm). Application technique with a pad on large surface areas is similar to that used with a roller.
9.6.2 Painter's mitts are lamb skin gloves that are dipped into the coating and are rubbed across the surface. They are ideal for application of coatings to odd-shaped surfaces such as pipes and railings.

9.7 Rate of Application--Properly written specifications require certain minimum and maximum dry-film thick

contin
nesses for each coat. The requirements should be augmented
with wet-film thickness figures calculated from the composi tion of the coating so that the proper dry-film thickness is
obtained. (Equation shown in 7.3.3.2.) Wet-film thickness
figures are useful to the inspector since he can often check as the work progresses to determine reasonably well that the
desired amount of coating is being applied. Later, when the
films are dry, the inspector should make spot checks with a
dry-film measuring gage to ascertain acceptability of the coatings. Film thickness measurements are more informative
than visual inspection, which may show only obvious
nonuniform application. Instruments for measuring film
thickness and the procedures for their use are described in
6.2.5 and 6.2.6. Nondestructive dry-film thickness gages and measurements are applicable to metal substrates only.
9.7.1 Thickness or coverage requirements apply to the whole structure, not some specific part. It is important that
the painting inspector check all areas and determine the film
thickness for each coat. For instance, if the "shop coat"
requires a minimum of2 mils (50 pm) dry film, the inspector
should ensure that it is obtained within the tolerances permitted in SSPC-PA2. The areas tested should be identi fied and recorded so that the dry thickness of added coating can be also determined. With nondestructive measuring instruments a 50-ft (15-m) long and 6-fit (1.8-m) high I-beam can be tested in 30 min and low areas if any, properly marked and recorded in the inspector's book. Because the
shop prime coat inspector may not be the person doing the field coat application inspection, it is very important to
record test results and send a copy to the field inspector in order to better determine thicknesses of subsequently applied coats.

D 3276
|H, Additional Considerations
[0.1 Ventilation--It is essential when painting in enclosed ^ces that adequate ventilation is provided for removal of Svents.
[0.2 Shopcoat Repair--Normally after erection work, as riveting, bolting, welding, straightening, etc., has completed satisfactorily, areas of the shopcoat will be
jjund to have been damaged. Damaged or bare areas must jjg thoroughly cleaned, prepared, and covered with one new Joat of shop or field primer. In addition, crevices and small jcks should be thoroughly cleaned and spot-primed. After
jjying, the crevices and cracks should be filled with an jjceptable caulking compound as required by the specificajon. The specified field coats should then be applied over the jjtire structure.
[0.3 Painting Schedule--As`indicated in 5.4.4, painting jjjould proceed by sections, bays, or parts of the work, and jach coat on each section should be applied entirely and accepted by the inspector before a succeeding coat is applied. Except for any shop coat touch ups made necessary by ^elding, etc., none of the metal that will be exposed to view jii the completed structure is to be field-painted until all concrete has been placed. Care must be taken by the contractor during painting operations to protect concrete [com being stained by the coating being applied. Any stained concrete surface must be restored to its intended color without damage to the concrete.
[0.4 Film Integrity--Each coat should be applied as a continuous film of uniform thickness, free of holidays and
pores. Any thin spots or areas missed in the application should be repainted and permitted to dry before the next coat is applied.
10.5 Recoat Time--Each coat must be dried throughout the full thickness of the film before application of the succeeding coat. Coating is considered dry for recoating when the next coat can be applied without the development of any detrimental film irregularities such as wrinkling, lifting, or loss of adhesion of the previous coat. For most coatings the time to dry for recoat, even under optimum conditions varies with their composition and that of the subsequent coat. Thus, an oil-based coating may take 2 to 4 days to harden sufficiently to be overcoated with a coating of the same type. However, it may take 3 or 4 months to harden to be satisfactorily overcoated with a vinyl coating or other type of coating containing strong solvents. The coating manufacturer's literature should be consulted for recoat times.
10.6 Coating System Failure--Failure of completed coating work may be the result of several factors. Most obvious is noncompliance with the specifications indicating insufficient inspection of surface preparation, coating quality, coating application, or conditions during application and drying/curing. On the other hand, failure may be due to improper specification of coatings for the intended use. Defective coatings should be removed in their entirety, the surface recleaned, and the specified coatings, or their alterna tives, applied.

V Many factors are important in ensuring proper application ofcoatings. The details are covered in this guide (Section 9). In particular, note: Dry-film thickness mea surements are of great importance be cause the protection of the substrate is directly related to the thickness of the coating. There are two ways of making the measurements, nondestructively or de structively (6.2.5).
Wet (Notched Gage)--This device has a senes of calibrated steps for mea suring thin to heavy coats. The true wet-film thickness lies between the highest step coated and the next highest that was not coated. This method is not as accurate as the interchemical gage. Interchemical Gage--This type of in strument is designed to measure the thickness of a wet film of paint. Nondestructive Film Thickness Gages are widely used for field and shop inspection. For ferrous metals they are based on magnetism, and for nonmagnetic metals, inductance and eddy currents. See guide for discussion of types. Dry (Tooke Gage)--The Tooke paint inspection gage is designed to measure paint film thickness by microscopic observation of a cut into the paint film. 12 Record time application completed 13 Tape test D 3359 14 Holiday detector

3. Apparatus
3.1 Impact-Type Wedge Bend, assembly illustrated in Fig, l.2 The instrument contains a 4-lb (1.82-kg) impacter rod with one flat end that slides in a vertical slotted guide and serves as a falling weight to hammer the wedge mandrel with the flat end. A knurled cover inserted in the wedge mandrel impact test hole serves as the impact point. When positioned properly the lifting knob on the impacter coincides with the zero mark on the guide tube. The spacer block is removed from the front edge of the wedge mandrel so that the taper is 0 to Vs in. (0 to 3.2 mm) front to back.

2 The Gardner Coverall Impact Tester available from BYK-Gardner, Inc. Gardner Laboratory, 2435 Linden Lane, Silver Spring, MD 20910, has been found satisfactory for this purpose. Use of other equipment should be agreed upon by the purchaser and seller.
S. Conditioning and Number of Tests
5.1 Test at least three replicate specimens under the conditions of temperature and humidity mutually agreed w upon between the purchaser and the seller. Unless otherwise Be specified by the purchaser and the seller, make measure ilaser ments at 73.5 3.5"F (23 2`C) and 50 5 % relative ihoul humidity after equilibrating at these conditions for at least 24 :onfi h.
6. Procedure
6.1 Place the specimen, coated side down, under the Vs-in. (3.2-mm) cylindrical mandrel. Slide the specimen to the rear of the mandrel platform until the edge is flush with the two studs located at the rear of the platform.
N,-' 2--Since the test is usually more severe if the panel is bent
parallel to the original rolling direction of the base metal, the direction of the bend'with respect to the "grain"' of the; base metal should be agreed uppn between the purchaser and the sellerfand reported.
6.2 Raise the remainder of the panel at a uniform velocity to bend the specimen 170 to 180in a time not to exceed 5 s.
6.3 Slide the spacer located under the impact platform to the extreme front ofthe tester and tighten it in place with the adjustment screws provided. This allows the impact platform to create a wedge that provides stress angles between 170 and 180.
N01' 3--The end of the specimen with the 180 stress angle is
defined as having a zero T (0T) bend.

3. Terminology
3.1 Definitions: 3.1.1 primer--the first of two or more coats of paint, varaish, or lacquer system (same as in Terminology D 16). 3.3.2 primer surfacer--a pigmented coating for filling minor irregularities which is sanded to obtain a smooth "inform surface preparatory to applying finish coats. A Primer surfacer is not usually applied over a primer.
Significance and Use
4.1 Primers and primer surfacers may be used over many
7. : '"Available from Standardization Documents Order Desk, Bldg. 4 Section D, i.01. M Robbins Ave., Philadelphia, PA 19111-5094.
different surfaces top coated with one or more of a variety of coatings and subjected to many kinds of wear and exposure.
4.2 The selection of the tests to be used for any given product or system must be governed by experience and by the requirement agreed upon between producer and user.
5. Panel Preparation
5.1 Treatment of Substrate--Preparation of test panels should include any cleaning treatment agreed upon between purchaser and seller or one of the following ASTM Practices: D 609, D 1730, D 1731, D 1732, D 1733 and D 2092, and Test Method D 2201.
5.2 Substrate, Film Thickness and Application Means-- Conduct performance tests on the specified substrate on coatings having a film thickness agreed upon between the purchaser and seller. Primers are generally applied to a dry film thickness of 0.3 to 1.5 mils (8 to 38 pm) and primer surfacers to film thickness of 0.7 to 2.0 mils (17 to 50 pm). Unless otherwise agreed upon, apply primers and primer surfacers in accordance with Test Method D 823.
5.3 Measurement ofFilm Thickness--Since the properties of the primer or primer surfacer can vary considerably with the thickness of the coating, it is important to know the film thickness. Measure the film thickness in accordance with Test Methods D 1400, D 1005, or D 1186.
5.4 Drying ofPrimer or Primer Surfacer: 5.4. i Before tests are rum air dry or bake the primer or primer surfacer according to the schedule and temperature and age as agreed upon between the purchaser and seller. 5.4.2 Overbake the primer or primer surfacer to deter mine the time/temperature effect on the physical and chem ical properties. Do this in accordance with Practice D 2454. 5.4.3 It may be desirable for some reason (handling, stacking, etc) to determine the various stages and rates of film formation in the drying or curing of primers and primer surfacers at room temperatures. Do this as described in Test Method D 1640.
6. Physical Properties of The Dry Film
6.1 Primers and primer surfacers are usually (but not always) topcoated. Therefore, many of the following tests should be run on the complete system (substrate/primer or primer surfacer/topcoat). Some of the tests however are for the untopcoated primer or primer surfacer. The properties required of a primer or primer surfacer depend on the intended end use and the tests to be used should be selected on the basis of experience and agreed upon between the purchaser and seller.
6.2 Abrasion Resistance--Determine the abrasion resis tance as described in either Test Method D 658 or D 968.
6.3 Adhesion: 6.3.1 The primer or primer surfacer of a specified sub strate as agreed upon by the purchaser and seller is subjected to an adhesion test to determine the degree of attachment the coating has to the substrate. 6.3.2 Determine the adhesion of the primer or primer surfacer as described either in Test Methods D2197 or D3359. 6.3.3 The above methods* in addition to measuring the adhesion of the. coating to the substrate, can also be used to determine the intercoat adhesion between the topcoat and

determining their resistance to failure under conditions of ^ humidity or water immersion. Failure in water tests is j ^jjally evidenced by blistering, dulling, softening or loss of
adhesion which does not disappear or recover upon evapora tion of the absorbed water.
6.18.2 Determine the resistance to failure under condi
tions of high humidity in accordance with Practice D 1735. 6.18.3 Determine the resistance to failure under condi
tions of water immersion in accordance with Practice D 870. This test is best suited for coating systems that will actually be soaked in water during service.
6.19 Weldability--In some instances it is necessary to weld metal that has been primed. The welding characteristics of a primer or primer surfacer may be tested in accordance with U.S. Military Specification MIL-P-46105 (MR), Section 4.4.11.

1-gal (4-L) sample is usually sufficient for the recommended tests, but for guidance in selecting a sampling plan, consult Recommended Practice E 105.
6. Liquid Paint Properties
6.1 Skinning--Paints containing a binder which dries by oxidation are subject to skin formation in a partially filled can. Since skins are insoluble in the paint, they must be removed before use. This test in a partially filled container indicates the tendency of a paint to skin. Examine the original sample for skins, both on the surface and in its mass. On a well-mixed, skin-free portion of the sample, perform a skinning test in accordance with Guide D 154.
6.2 Condition in Container--Thickening, settling, and separation are undesirable and objectionable if the paint cannot be reconditioned with a reasonable amount of stirring. The referenced method covers procedures for deter mining changes in properties of paints after storage. Deter mine the condition in the container in accordance with Method 3011 of U.S. Federal Test Method Standard No. 141.
6.3 Coarse Particles and Foreign Matter--Paints must be free of coarse particles and foreign matter to form a uniform film of good appearance, a typical maximum being 1 weight % of the total paint. Determine the percent of coarse particles and foreign matter in accordance with Test Method
D 185. 6.4 Fineness ofDispersion--The more finely a pigment is
dispersed the more efficiently it is being utilized. One method for measuring the degree of dispersion (commonly referred to as "fineness of grind") is to draw the product
down a tapered groove varying in depth from 4 to 0 milf)
(100 to 0 pm). The point at which continuous groupings of;:
particles or agglomerates, or both, protrude through tlf, l
surface of the wet film is taken as the dispersion res
Higher readings in Hegman units or lower readings in mils or
micrometres indicate better dispersion. Determine the fine-,
ness of dispersion in accordance with Test Method D 1210."
6.5 Weight per Gallon--The density of a paint as mea:
sured by weight per gallon or kilograms per litre is used to
assure product uniformity, batch to batch, and provides
check against the theoretical weight calculated from the!
formula. The density is expressed as the weight in pound!
avoirdupois of 1 U.S. gal of the paint at a specified
temperature. Determine weight per gallon or kilograms pet;
litre in accordance with Test Method D 1475, using i
calibrated weight per gallon cup.
6.6 Consistency--Paints of a given type should fall within'
a stated consistency range for satisfactory reproduction oflj
specific formula. In the referenced test method, consistency
is defined as the load in grams required to produce th<
specified rate of shear. Determine consistency in accori
with Test Method D 562.
6.7 Flash Point--When the flash point of a material is
required for shipping information, use Test Method^
D 1310, D 3278, orD93.
;
6.8 ColorAcceptance--This method gives an indication c
the ability of the paint to be tinted with tinting systems a common use. Determine color compatibility as agreed upff1lf !
between the purchaser and seller.

^operties of the liquid paint. The referenced test method jpvers the determination of the rheological properties and is
.jjticularlv suited for use with paints that display thixotropic Jjjaracteristics. Determine the rheological properties in accprdance with Test Method D 2196.
6.10 Absorption--This method provides a rapid determi nation of the relative penetration of the binder into the juiface. It provides a rough measure of the wetting and penetrating properties of liquid materials. Loss of binder and
resultant change in pigment volume, as the film dries, are indicated by this test. Determine the absorption in accord ance with Method 4421 of U.S. Federal Test Method Standard No. 141.
7, Paint Application and Filin Formation
7.1 Application ofBrushed Films--Refer to Method 2131 or 4321 of U.S. Federal Test Method Standard No. 141 to determine the brushing properties of a coating. Method 4321-1 is quite subjective although someone experienced in tiie art can obtain consistent results, particularly in the determination of the "drag" properties.
7.2 Applications of Sprayed Films--Refer to Method 2131 or 4331 of U.S. Federal Test Method Standard No. 141 to determine the spraying properties of a coating. Method 4331 is very subjective and should be performed by an individual skilled in the art of using spray equipment.
7.3 Drying Time--The drying time of an interior finish is important in determining when a freshly painted room can be put back to use. The test can also be used to determine whether or not the drying properties of a paint have changed during storage. Any one or several of the test methods that cover the determination of the various stages and rates of film formation in the drying or curing of organic coatings may be used. For example, if two coats are specified, the determination of "dry-to-recoat" times will be important. Determine the appropriate drying time in accordance with Test Method D 1640.
7.4 Leveling Properties--Leveling is an important factor when smooth surfaces are to be produced. The referenced test method covers the laboratory determination of the relative leveling characteristics of liquid coatings. Determine leveling characteristics in accordance with Test Method D2801.
7.5 Producing Films of Uniform Thickness--Method D823 covers the preparation of coating films of uniform thickness essential in conducting tests.
7.6 Roller Coating Properties--The referenced method outlines a procedure for making an evaluation of a material's characteristics when applied by a roller. Determine roller coating properties in accordance with Method 4335 of U.S. Federal Test Method Standard No. 141.
7.7 Working Properties--Working properties of a paint are generally compared to a standard or described by re quirements in the product specification. Determine work ing properties in accordance with Method 4541 of U.S. Federal Test Method Standard No. 141.
8. Appearance of Dry Paint Film
8.1 Color Difference ofOpaque Materials by Visual Com parison--Visual comparison of color is fast and often acceptable. The referenced practice covers the spectral.
photometric, and geometric characteristics of light source, illuminating and viewing conditions, sizes of specimens, and general procedures to be used in the visual evaluation of color differences of opaque materials. Determine color difference in accordance with Practice D 1729.
8.2 Color Differences of Opaque Materials by Instrument Evaluation--Color difference between a product and the standard can be measured by instrument. The referenced method covers the instrumental determination of small color differences, observable in daylight illumination, between nonfluorescent, nonmetameric, opaque surfaces such as paint specimens. If metamerism is suspected, visual evalua tion (8.1) should be used to verify instrumental results. Determine the color difference in accordance with Method D 2244.
8.3 Specular Gloss (Sheen)--The test method given, using the 85 geometry, is useful in characterizing the low angle appearance of flat paints. Determine 85 gloss in accordance with Test Method D 523.
8.4 Hiding Power--Hiding power is a measure of the ability of a coating to hide the substrate. It is, however, dependent on uniform film thickness which is influenced by the flow, leveling, and application properties of the enamel. Test Method D 344 uses brush application and compares the enamel to a standard. Test Method D 2805 uses an appli cator, bar and is more reproducible and measures smaller differences than D 344. Determine hiding power in accord ance with Test Methods D 344 or D 2805.
9. Properties of Dry Paint Film
9.1 Adhesion--Measure the adhesion of the paint by testing in accordance with Test Method D 2197.
9.2 Cleanability--The ability to remove marks satisfacto rily without damaging the film is important with interior finishes.
9.2.1 Scrub Resistance--The test for scrub resistance of interior latex flat wall paint can be applied to the solventthinned type. Use Test Method D 2486.
9.2.2 Washability--The referenced method determines the washability of a paint by subjecting a soiled film of the dried paint to the cleaning action of a wet sponge and cake grit soap. Determine the washability in accordance with Method 6141 of U.S. Federal Test Method Standard No. 141.
9.3 Elongation--Elongation is a measure of flexibility of a paint film. Determine elongation in accordance with Test Methods D 1737 or D 522.
9.4 Fume Resistance--Some paints exhibit a change in appearance (usually color) when subjected to foul atmos pheres, for example, air containing certain sulfur com pounds. There is no standard test method for determining the ability of a paint to resist this change.
9.5 Yellowness Index--The referenced test method is used for white or near white specimens to determine color departure from white toward yellow or color change towards yellow on exposure or treatment. Determine the yellowness index in accordance with Test Method E 313.
10. Analysis of Paint
10.1 If a specification requires certain raw materials or certain components in a given amount, then chemical

D
analysis is required. Chemical analysis determines whether
the specified components are present and if they are, in what amounts. It does not necessarily establish paint quality which can be greatly affected by manufacturing techniques. No single schematic analysis is comprehensive enough to cover the wide variety of materials used in paint compositions.
10.2 Volatile Content--The percent of volatile matter indicates the thinner loss from the film as it dries. The referenced test method covers the determination of the volatile content of solvent-type paints. The quantity deter mined subtracted from 100 % gives the nonvolatile content of the coating. Determine the volatile content in accordance with Test Method D 2369.
10.3 Water Content--The referenced test method covers the determination of water in paint and related materials by distilling the sample with a volatile solvent. Determine water content in accordance with Test Method D 1208.
10.4 Pigment Content--'Pigment provides the hiding and
color and influences many other properties of a coating. The referenced test method describes the procedure for the quantitative separation of the vehicle from the pigment in solvent-type coatings. It is used to determine the weight percent pigment in the paint. Determine the pigment content in accordance with Test Method D 2371.
10.5 Separation of Vehicle--The recommended proce dure describes the separation of vehicle from certain solventtype paints. The separated vehicle is subjected to further analysis. Separate the vehicle in accordance with Method D 2372.
10.6 Identification of Vehicle Solids--The suggested method covers the qualitative characterization or identifica tion of separated paint vehicle solids by infrared spectros copy. It is useful in detecting uniformity, batch to batch, and the presence of adulterants. Characterize vehicle solids in accordance with Method D 2621.

(jiuffle furnace and allow it to cool to room temperature, greak up the ash into fine particles with a glass stirring rod, leaving the rod with the container through the filtering step.
9.7 Add 10 mL of HN03 (1+1), taking care to avoid losses due to spattering in case the ash reacts vigorously with l(ie acid. Heat carefully on a hot plate until 2 to 3 mL of solution remain. Add an additional 10 mL of HNOs (1 + 1) and continue heating on the hot plate until less than 5 mL of the solution remains.
9.8 Filter the solution through medium-porosity filter paper into a 50-mL volumetric flask. If the filtrate is not clear, refilter through fine-porosity filter paper. Wash the container three times with 2.5 mL of hot ammonium acetate solution (6.3), each time transferring the washings to the glter paper. Wash the filter paper several times with water, adjust the volume to 50 mL with water and mix.
9.9 Aspirate the test solution and determine the absorbance in the same manner in which the instrument was calibrated. Determine the concentration of lead, cadmium, or cobalt in micrograms per millilitre from the calibration curve. If the absorbance is above the range covered by the calibration curve, dilute an aliquot of the sample solution to a suitable volume with ammonium acetate diluting solution.
No t ' 5--For maximum accuracy, calibration and standardization (Section 8) should be completed just prior to aspirating the sample solution.
N' 6--The method of standard additions may be used to improve the accuracy of the analysis. This method is particularly recommended for use with unknown samples where matrix effects may be potentially significant. For a detailed description of the procedure and calculations used in the method of standard additions, consult a standard text on atomic absorption spectroscopy or the instruction manual provided by the instrument manufacturer.
10. Calculation
10.1 Calculate the mean concentration of lead, cadmium, or cobalt in the nonvolatile portion of the sample as follows:
lead, cadmium or cobalt, ppm (mg/kg) in nonvolatile = (CxFx 5000)/(NVx S)
where: C = concentration of lead, cadmium, or cobalt in the
aspirated specimen solution, (pg/mL), F -- dilution factor from 9.9 (volume diluted to/volume
of aliquot), 5000 = factor derived from multiplying the 50-mL volume
obtained in procedure in 9.8 by 100 (to convert NV used to a whole number) and 10 (to obtain ppm), then dividing by 106 (to convert grams of sample to
H8).
NV = percent nonvolatile of paint sample (use 100 if sample was a dried film), and
S = sample, g.
11. Report
11.1 Report the lead, cadmium, or cobalt content of the nonvolatile content of'the sample and whether the analysis was conducted on a liquid coating or a dried film.
12. Precision and Bias9
12.1 The precision estimates are based on an inter laboratory study in which seven different laboratories ana lyzed in duplicate, on two different days, four samples of water-reducible paints and four samples of solvent-reducible paints containing from 0.01 to 5 % lead, 50 to 150 ppm (mg/kg) cadmium, and 50 to 2000 ppm cobalt. The withinIaboratory coefficient of variation was found to be 3.4 % relative at 24 degrees offreedom for lead, 3.7 % relative at 15 degrees of freedom for cadmium, and 3.3 % relative at 21 degrees of.freedom for cobalt. The between-laboratory coef ficient of variation was 9.3 % relative at 20 df for lead, 8.9 % relative at 11 df for cadmium, and 5.5 % relative at 17 df for cobalt. Based on these coefficients, the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
12.1.1 Repeatability--Two results, each the mean of du plicate determinations, obtained by the same operator on different days should be considered suspect if they differ by more than 11 % relative for ail three metals.
12.1.2 Reproducibility--Two results, each the mean of duplicate determinations, obtained by operators in different laboratories should be considered suspect if they differ by more than 28 % relative for lead or cadmium or by more than 17 % relative for cobalt.
12.2 Bias: 12.2.1 The true value for the amount of lead present in the solids of a coating should be between 97 and 111 % of the experimental value. , 12.2.2 The true value for the amount of cadmium present in the solids of a coating should be between 77 and 143 % of the experimental value. 12.2.3 The true value for the amount of cobalt present in the solids of ia coating should be between 96 and 120 % of the experimental value.

3. Conditions Affecting Performance of Water-Borne Floor Paints
3.1 Practical requirements affecting and performance of water-thinned floor paints may vary with;
3.1.1 Substrate type, such as type and quality of wood, concrete, metal, or composition flooring. The use of water borne floor paints is generally restricted to previously painted surfaces or unpainted concrete.
3.1.2 Substrate conditions such as porosity, hardness, smoothness, or in the case of unpainted concrete, alkalinity. Cleanliness is very important as traces of oily contaminants can cause water-borne floor paints to peel.
3.1.3 Environmental conditions such as temperature and humidity at the time of application and during drying. As these paints contain water as a. thinner, the floor does not have to be completely dry before application. However, low temperature during the drying period may cause poor film formation.
3.1.4 Substrate Aspects--If construction defects are such that excessive moisture makes its way through the substrate, or if the substrate is in direct contact with damp ground, blistering, flaking, or peeling may result.
4. Definitions
4.1 For definitions of terms used in this guide, refer to Definitions D 16.
5. Sampling
5.1 Prior to sampling, the condition of the container should be established since damage to it may cause evapora tion, skinning, or other undesirable effects in the coating. Determine the condition of the paint in accordance with 6.1 and 6.2.
5.2 Sample in accordance with Section 4.2.1 of Method 1021 of Federal Test Method No. 141. Determine the weight per gallon (or kilograms per litre) in accordance with Test Method D 1475. Repeat this procedure until successive values agree within 0.1 lb (45 g) or as agreed upon between the pur chaser and the seller. Samples for testing may then be taken.
5.3 Specify the amount of sample, the package sizes, and identification codes to assure a representative sample. A 1-gal sample is usually sufficient for the recommended tests, but for guidance in selecting a sampling plan, consult Practice E 105.* 6

6. Liquid Paint Properties
6.1 Condition in Container--Thickening, settling, and separation are undesirable and objectionable if a paint cannot be reconditioned and made suitable for application with a reasonable amount of stirring. The referenced methods covers procedures for determining changes in properties of paints after storage. Determine the condition in the container in accordance with Method 3011 of Federal Test Method Standard No.' 141.
6.2 Coarse Particles and Foreign Matter--Paints must be free of coarse particles to form uniform films of good appearance, a typical maximum being 1 weight % of total paint. The specified test with a No. 325 (45-pm) sieve gives the percent of these particles in a paint. Determine coarse particles and foreign matter in accordance with Test Methods D 185.

6.3 Density or Weight per Gallon--The density as mea sured by weight in pounds per gallon (kilograms per litre) is used to assure product uniformity from batch to batch. In the referenced method, density is expressed as the weight in pounds of 1 U.S. gal (or kilograms per litre) of the paint at a specified temperature. Determine density in accordance with Test Method D 1475 using a.calibrated cup.
6.4 Fineness ofDispersion--The more finely a pigment is
dispersed, the more efficiently it is being used. One method for measuring the degree of dispersion (commonly referred to as "fineness of grind") is to draw the material down a calibrated, tapered groove in a hardened, steel block with the groove varying in depth from 4 to 0 mils (100 to 0 pm) and calibrated Hegman 0-8. The point at which continuous groupings of particles or agglomerates, or both, are visible through the surface of the liquid is taken as the fineness reading. Lower readings in mils or pm or higher readings in Hegman units indicate better fineness of dispersion. Deter mine fineness of dispersion in accordance with Test Method D 1210.
6.5 Consistency--Consistency is important, relating to application and flow, and should fall within a range agreed
upon. In the referenced method consistency is defined as the load in grams required to produce a specified rate of shear and also expressed in Krebs units. Other methods may used as agreed upon between the purchaser and the seller Determine consistency in accordance with Test Method D 562.
6.6 pH--The pH of a water-thinned paint depends on the type of latex used and the general formulation. It may vary from about 5 to 10. pH does not determine the quality of% paint and should not be used to assure product uniformity. 4 change in pH during storage may indicate poor stability ora change in properties of a water-thinned paint. Determine pft in accordance with Test Method E 70.
6.7 Freeze-Thaw Resistance--Water-thinned paints may be subjected to freezing conditions during shipping and storage. Suitably stabilized paints resist several cycles of freezing and thawing without showing deleterious changes. The referenced method covers the determination of the extent to which water-thinned floor paints, utilizing synthetic latices or synthetic resin emulsions as vehicles, retain their original properties when subjected to freezing and subse. quent thawing. Determine freeze-thaw resistance in accordance with Test Method D 2243.
6.8 Package Stability--Since paints cannot normally be used immediately after manufacture, they must remain stable in the can for some time. At normal temperatures, most water-thinned floor paints can be stored for over a year with little change in properties. The referenced method covers the change in consistency and in certain related properties that may take place in packaged latex paint when stored at temperatures above freezing. Determine package stability in accordance with Test Method D 1849.
6.9 Resistance to Microorganisms--Bacteria in a water borne floor paint can cause gassing, putrefactive or fermen tative odors, and loss of viscosity. Determine if the paint contains living bacteria and if it is resistant to attack by bacteria in accordance with Test Method D 2574.
7. Paint Application and Film Formation
7.1 Application of Brushed Films--Brushed films should be smooth and free of seeds, color streaking, and brush marks. Test brush application in accordance with Method 2141 of Federal Test Method Standard No. 141.
7.2 Brushing Properties--The specified method covers a means for determining the brushing properties of coatings. The test is quite subjective; however, someone experienced in the art can produce quite consistent results, particularly in the determination of "drag" qualities. Floor paints are generally applied to horizontal surfaces but evaluation on vertical surfaces may be necessary to determine performance on stair risers, railings, posts, baseboards, etc. Determine the brushing properties in accordance with Method 4321 of Federal Test Method Standard No. 141.
7.3 Roller Coating Properties--Floor paints are frequently applied by roller. The referenced method outlines a proce dure for evaluating a material's characteristics when applied by a roller. Determine roller coating properties in accordance with Method 4335 of Federal Test Method Standard No. 141.

7.4 Drying Properties--The drying time of a floor paint is important in determining when a freshly painted floor of stair may be subjected to traffic. Slow drying of the film may result in dust pickup, poor appearance and, if used on an exterior surface, rain or dew may cause a nonuniform appearance. Generally, water-thinned paints are dryto-touch in 1 or 2 h when the water has evaporated from the film. Determine drying time in accordance with Test Methods D 1640.
7.5 Leveling Properties--Leveling is an important factor when uniform surfaces are to be produced, as it affects hiding and appearance. The referenced method covers the labora tory determination of the relative leveling characteristics of liquid coatings. Determine leveling characteristics in accord ance with Test Method D 4062.
7.6 Producing Films of Uniform Thickness--Test Methods D 823 covers the preparation of various films of uniform thickness essential in conducting tests.
8. Appearance of the Dry Film
8.1 Color Difference ofOpaque Materials by Visual Eval uation--Visual comparison of color is fast and often accept able although numerical values are not obtained. The referenced method covers the spectral, photometric, and geometric characteristics ofthe light source, illuminating and viewing conditions, size of specimens, and general proce dures to be used in the visual evaluation of color differences of opaque materials. Determine color difference in accord ance with Practice D 1729.
8.2 Color Differences of Opaque Materials by Instru mental Evaluation--Color difference between a product and the standard can be measured by instrument Generally the tolerance is agreed upon between the purchaser and the seller. The referenced method covers the calculation of instrumental determinations of small color differences, ob servable in daylight illumination, between nonfiuorescent, nonmetameric, opaque surfaces such as coated specimens. If metamerism is suspected, visual evaluation (8.1) should be used to verify instrumental results. Calculate the color difference measured instrumentally in accordance with Method D 2244.
8.3 Gloss--Water-thinned floor paints generally have a semi-gloss finish which resists penetration of dirt and im proves washability. A range from 20 to 40 may be considered typical. Determine the specular gloss in accordance with Test Methods D 523.
8.4 Hiding Power (Dry Opacity)--Hiding power is the measure of the ability of a paint to hide the substrate. It is, however, dependent upon uniform film thickness which is influenced by flow and leveling. Test Method D 344 is a practical test in which paint is applied with a brush, film thickness is approximately measured, opacity is evaluated visually as compared to a standard paint, and results are affected by flow and leveling application properties of the paint. Test Method D2805 is considered to be a more I precise and accurate test that does not need a material paint standard. Paint is applied with an applicator bar to minimize the effects of flow and leveling, film thickness is rigorously measured, and opacity is instrumentally evaluated. Deter
mine hiding power in accordance with Test Methods D 344 or D 2805.
9. Properties of the Dry Film
9.1 Abrasion Resistance--Abrasion resistance is a mea sure of the ability of a dried film to withstand wear from foot traffic and marring from objects rolled or pulled across the surface. Determine abrasion resistance in accordance with Test Methods D 658 or D 968.
9.2 Elongation--Elongation is a measure of the flexibility of a paint film. Determine elongation in accordance with Test Methods D 1737 or D 522.
9.3 Adhesion--Adhesion is the property of the film that resists removal from the substrate when scuffed or scraped. It is an important property in a floor paint. Determine adhe sion in accordance with Test Method D 2197.
9.4 Resistance to Chemicals--An important property of a floor paint is its ability to resist spotting, softening, or removal when subjected to household chemicals or strong cleaners. Determine resistance to chemicals in accordance with Test Method D 1308.
9.5 Exterior Exposure--If the paint is intended for use on porches, decks, or outside stairways and railings, tests for resistance to exterior exposure may be required and may include the following:
9.5.1 Conducting Exterior Exposures--In conducting ex terior exposures, refer to Practice D 1006 and Classification D 1848.
9.5.2 Wood Panel Description--In establishing exposure performance, use the panels as described in Specification D 358.
9.5.3 Chalking Resistance--Determine the chalkresistance rating by reference to Test Method D 659.
9.5.4 Checking Resistance--Determine the checking re sistance rating by reference to Test Method D 660.
9.5.5 Cracking Resistance--Determine the cracking re sistance rating by reference to Test Method D 661.
9.5.6 Erosion Resistance--Determine the erosion resist ance rating by reference to Test Method D 662.
9.5.7 Flaking Resistance--Determine the flaking resist ance rating by reference to Test Method D 772.
10. Analysis of Paint
10.1 Chemical Analysis--If a specification requires cer tain raw materials or certain components in a given amount then chemical analysis is required to determine whether the specified components are present and in what amounts. Analysis does not necessarily establish paint quality which can also be greatly affected by manufacturing techniques. Most ASTM analytical methods apply to solvent-reducible coatings. However, some of these can be adapted for analysis of water-borne paints.
10.2 Volatile Content--The percent of volatile matter indicates the thinner loss from the film as it dries. This quantity subtracted from 100 % gives the nonvolatile con tent. Determine the volatile content in accordance with Test Method D 2369.
10.3 Pigment Analysis--The analysis of pigment may be required if the product is covered by a specification or if it is

DU P050297656
agreed between the purchaser and the seller. Analyze the pigment in accordance with selected test procedures from Methods D 215.

Designation: D 3359 - 90
Standard Test Methods for Measuring Adhesion by Tape Test1
This standard is issued under the fixed designation D 3359; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (t) indicates an editorial change since the last revision or reapproval.
These methods have been approvedfor use by agencies ofthe Department ofDefense. Consult the DoD Index ofSpecifications and Standardsfor the specific year ofissue which has been adopted by the Department ofDefense.
j. Scope
U These test methods cover procedures for assessing the adhesion of coating films to metallic substrates by applying and removing pressure-sensitive tape over cuts made in the film.
1.2 Test Method A is primarily intended for use at job sites while Test Method B is more suitable for use in the laboratory. Also, Test Method B is not considered suitable for films thicker than 5 mils (125 (im).
N' 1--Subject to agreement between the purchaser and the seller.
Test Method B can be used for thicker films if wider spaced cuts are employed.
1.3 These test methods are used to establish whether the adhesion of a coating to a substrate is at a generally adequate level. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measure ment are required.
N' 2--It should be recognized that differences in adheiability of
the coating surface can affect the results obtained with coatings having the same inherent adhesion.
1.4 In multicoat systems adhesion failure may occur between coats so that the adhesion of the coating system to the substrate is not determined.
1.5 This standard does not purport to address the safety problems associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

3. Summary of Test Methods
3.1 Test Method A--An X-cut is made in the film to the substrate, pressure-sensitive tape is applied over the cut and then removed, and adhesion is assessed qualitatively on the 0 to 5 scale.
3.2 Test Method B--A lattice pattern with either six or eleven cuts in each direction is made in the film to the substrate, pressure-sensitive tape is applied over the lattice and then removed, and adhesion is evaluated by comparison with descriptions and illustrations.
4. Significance and Use
4.1 If a coating is to fulfill its function of protecting or decorating a substrate, it must adhere to it for the expected service life. Because surface preparation (or lack of it) has a drastic effect on adhesion of coatings, a test method for evaluating adhesion to different surface treatments or of different coatings to the same treatment is of considerable use in the industry.
4.2 The limitations of all adhesion methods and the specific limitation of this test method to lower levels of adhesion (see 1.3) should be recognized before using it. The intra- and inter-laboratory precision of this test method is similar to other widely-accepted tests for coated substrates (for example, Test Method D2370 and Test Method D 4060), but this is partly the result of it being insensitive to all but large differences in adhesion. The limited scale of 0 to 5 was selected deliberately to avoid a false impression of being sensitive.
TEST METHOD A--X-CUT TAPE TEST
5. Apparatus and Materials
5.1 Cutting Tool--Sharp razor blade, scalpel, knife or other cutting devices. It is of particular importance that the

cutting edges be in good condition. 5.2 Cutting Guide--Steel or other hard metal straightedge
to ensure straight cuts. 5.3 Tape-One-inch (25-mm) wide semitransparent pres
sure-sensitive tape with an adhesion strength agreed upon by the supplier and the user is needed. Because of the variability in adhesion strength from batch-to-batch and with time, it is essential that tape from the same batch be used when tests are to be run in different laboratories. If this is not possible the test method should be used only for ranking a series of test coatings.
5.4 Rubber Eraser, on the end of a pencil. 5.5 Illumination--A light source is helpful in determining whether the cuts have been made through the film to the substrate.
6. Test Specimens
6.1 When this test method is used in the field, the specimen is the coated structure or article on which the adhesion is to be evaluated.
6.2 For laboratory use apply the materials to be tested to panels of the composition and surface conditions on which it is desired to determine the adhesion.
N' 3--Applicable test panel description and surface preparation
methods are given in Methods D 609 and Practices D 1730 and D 2092.
. N' 4--Coatings should be applied in accordance with Test
Methods D 823, or as agreed upon between the purchaser and the seller. No t e 5--If desired or specified, the coated test panels may be
subjected to a preliminary exposure such as water immersion, salt spray, or high humidity before conducting the tape test. The conditions and time of exposure will be governed by ultimate coating use or shall be agreed upon between the purchaser and seller.
7. Procedure
7.1 Select an area free of blemishes and mitior surface imperfections. For tests in the field, ensure that the surface is clean and dry. Extremes in temperature or relative humidity may affect the adhesion of the tape or the'coating.
7.2 Make two cuts in the film each about 1.5 in. (40 mm) long that intersect near their middle with a smaller angle of between 30 and 45. When making the incisions, use the straightedge and cut through the coating to the substrate in one steady motion.
7.3 Inspect the incisions for reflection of light from the metal substrate to establish that the coating film has been penetrated. If the substrate has not been reached make another X in a different location. Do not attempt to deepen a previous cut as this may affect adhesion along the incision.
7.4 Remove two complete laps of the pressure-sensitive tape from the roll and discard. Remove an additional length at a steady (that is, not jerked) rate and cut a piece about 3 in. (75 mm) long.
7.5 Place the center of the tape at the intersection of the cuts with the tape running in the same direction as the smaller angles. Smooth the tape into place by finger in the area of the incisions and then rub firmly with the eraser on the end of a pencil. The color under the transparent tape is a useful indication of when good, contact has been made.
7.6 Within 90 30 s of application, remove the tape by seizing the free end and pulling it off rapidly (not jerked):' back upon itself at as close to an angle of 180 as possible.
7.7 Inspect the X-cut area for removal of coating from the
substrate or previous coating and rate the adhesion in accordance with the following scale:
5A No peeling or removal, 4A Trace peeling or removal along incisions or at their intersection, 3A Jagged removal along incisions up to Vis in. (1.6 mm) on either
side, 2A Jagged removal along most of incisions up to */s in. (3.2 mm) on
either side, 1A Removal from most of the area of the X under the tape, and 0A Removal beyond the area of the X.
7.8 Repeat the test in two other locations on each test panel. For large structures make sufficient tests to ensure that the adhesion evaluation is representative of the whole surface.
7.9 After making several cuts examine the cutting edge and, if necessary, remove any flat spots or wire-edge by abrading lightly on a fine oil stone before using again. Discard cutting tools that develop nicks or other defects that tear the film.
8. Report
8.1 Report the number of tests, their mean and range, and for coating systems, where the failure occurred that is, between first coat and substrate, between first and second coat, etc.
8.2 For field tests report the structure or article tested, the location and the environmental conditions at the time of testing.
8.3 . For test panels report the substrate employed, the type of coating, the method of cure, and the environmental conditions at the time of testing.
8.4 If the adhesion strength of the tape has been deter mined in accordance with Test Method D 3330, report the results with the adhesion rating(s).
9. Precision and Bias6
9.1 In an interlaboratory study of this test method in which operators in six laboratories made one adhesion measurement on three panels each of three coatings covering a wide range of adhesion, the within-laboratories standard deviation was found to be 0.33 and the between-laboratories 0.44. Based on these standard deviations, the following criteria should be used forjudging the acceptability of results, at the 95 % confidence level:
9.1.1 Repeatability--Provided adhesion is uniform over a large surface, results obtained by the same operator should be considered suspect if they differ by more than 1 rating unit for two measurements.-
9.1.2 Reproducibility--Two results, each the mean of triplicates, obtained by different operators should be consid ered suspect if they differ by more than 1.5 rating units.
9.2 Bias cannot be established for these test methods.

U Test Specimens
11.1 Test specimens shall be as described in Section 6.
12. Procedure
12.1 Where required or when agreed upon, subject the specimens to a preliminary test before conducting the tape lest (see Note 3). After drying or testing, select an area free of blemishes and minor surface imperfections.
12.2 Place the panel on a firm base and under the illuminated magnifier make parallel cuts as follows:
12.2.1 For coatings having a dry film thickness up to and including 2.0 mils (50 pm) space the cuts 1 mm apart and make eleven cuts unless otherwise agreed upon.
12.2.2 For coatings having a dry film thickness between 2.0 mils (50 pm) and 5 mils (125 pm), space the cuts 2 mm apart and make six cuts. For films thicker than 5 mils use Test Method A.
12.2.3 Make all cuts about 3A in. (20 mm) long. Cut through the film to the substrate in one steady motion using just sufficient pressure on the cutting tool to have the cutting edge reach the substrate. When making successive single cuts with the aid of a guide, place the guide on the uncut area.
12.3 After making the required cuts brush the film lightly with a soft brush or tissue to remove any detached flakes or ribbons of coatings.
12.4 Examine the cutting edge and, if necessary, remove any flat spots or wire-edge by abrading lightly on a fine oil stone. Make the additional number of cuts at 90 to and centered on the original cuts.
12.5 Brush the area as before and inspect the incisions for reflection of light from the substrate. If the metal has not been reached make another grid in a different location.
12.6 Remove two complete laps of tape and discard. Remove an additional length at a steady (that is, not jerked) rate and cut a piece about 3 in. (75 mm) long.
12.7 Place the center of the tape over the grid and in the area of the grid smooth into place by a finger. To ensure good contact with the film rub the tape firmly with the eraser on the end of a pencil. The color under the tape is a useful indiction of when good contact has been made.
12.8 Within 90 30 s of application, remove the tape by seizing the free end and rapidly (not jerked) pulling it off at as close to an angle of 180 as possible.
12.9 Inspect the grid area for removal of coating from the substrate or from a previous coating using the illuminated magnifier. Rate the adhesion in accordance with the fol
lowing scale illustrated in Fig. 1:
5B The edges of the cuts are completely smooth; none of the squares of the lattice is detached.
4B Small flakes of the coating are detached at intersections; less than 5 % of the area is affected.
3B Small flakes of the coating are detached along edges and at intersections of cuts. The area affected is 5 to 15 % of the lattice.
2B The coating has flaked along the edges and on parts of the squares. The area affected is 15 to 35 % of the lattice.
1B The coating has flaked along the edges of cuts in large ribbons and whole squares have detached. The area affected is 35 to 65 % of
the lattice. 0B Flaking and detachment worse than Grade 1.
12.10 Repeat the test in two other locations on each' test panel.
13. Report
13.1 Report the number of tests, their mean and range, and for coating systems, where the failure occurred, that is, between first coat and substrate, between first and second coat, etc. .
1.3.2 Report the substrate employed, the type of coating and the method of cure.
13.3 If the adhesion strength of the tape has been deter mined in accordance with Test Method D 3330, report the

3. Significance and Use
3.1 Organic coatings on exterior exposure are subjected to attack by degrading elements of the weather, particularly ultraviolet light, oxygen, and water. This practice may be used for evaluating the behavior of films exposed in appa ratus that produces ultraviolet radiation, high temperatures, and water condensation on the films. This apparatus is used

to make an early materials comparison of the exterior exposure quality of paints. However, light sources, such as the carbon arc, that emit a significant amount of radiation at wavelengths shorter than those in natural sunlight, may cause results that lead to unrealistic evaluations of weath ering properties.
3.2 This test method produces failure of films at a very rapid rate because the test is run without filters. The unfiltered carbon arc produces light that does not exist at the earth's surface. Failure caused by this light may bear no relationship to failures in natural sunlight It is essential to have a control material of known performance of a similar vehicle type in every test. Substrates that have good thermal insulating properties should not be used because sufficient condensation cannot be obtained.
3.3 As no single light exposure apparatus, with or without water, can be specified as a direct simulation of natural exposure, this practice does not imply expressly, or other wise, a specific correlation with outdoor exposure. It has, however, been useful in many instances.
3.4 Since climatic conditions vary with respect to time, geography, and topography, it may be expected that the effects of natural exposure will vary accordingly. All mate rials are not affected equally by the same environment. Results obtained by use of this practice should not be represented as equivalent to those of any outdoor weathering test unless the degree of quantitative correlation has been established for the material in question.
3.5 Variations in results may be expected when operating conditions among similar type instruments vary within accepted limits of this standard procedure.
4. Hazards
4.1 Warning--Never look directly at the carbon arc because ultraviolet radiation can damage the eye. Most carbon arc apparatus machines are equipped with door safety switches, but users of old equipment must be certain to turn the operate switch off before opening the. test chamber door.
4.2 This light source generates ozone and nitrous oxides. Exhaust from the cabinet should be vented to the atmo
sphere.
5. Test Specimens
5.1 Unless otherwise agreed upon, choose panels that meet the applicable base panel requirements specified in Test Methods D 609 and Practices D 1730, D 1731, D 1732, or D 2092. Select panel sizes suitable for exhibiting the failure mode to be observed.
5.2 Apply the coatings to flat panels with the base panel material, method of application, coating system, film thick ness, and method of drying consistent with the anticipated end use, or as mutually agreed upon between the producer and the user.
5.3 Unless otherwise agreed upon, coat test panels in accordance with Test Methods D 823 and measure the film thickness in accordance with an appropriate procedure selected from Test Methods D 1005, D 1186, D 1212, or D 1400. Nondestructive methods are preferred because panels so measured do not need to be repaired.
5.4 Unless otherwise specified, before exposing coated
panels in the apparatus, condition them at 73.5 3.5F (23 I-5- no refe
2C) and 50 5 % relative humidity for one of the be tests cor following periods in accordance with the type of coating: iccompanie

6.1 Type EH Apparatus (open-flame carbon arc), 0f 10.1.1 1 Practice G 23, without filters.7
7. Procedure
7.1 Mount the test specimens vertically both above and below the horizontal center line of the source of radiation. Rotate the specimens from upper to lower rack to provide uniform exposure conditions over their surface. Specimens should be exposed approximately as many hours in the top rack as in the bottom rack, but need not be inverted.
7.2 Base temperature measurement and control on the black panel thermometer unit. Support the panel with the thermometer attached in the top row of the specimen drum or rack in the same manner as the test specimens so that it will be subjected to the same influences. If necessary, read black panel temperatures through the window in the test chamber without opening the door. The black panel temperature shall reach a maximum of 145 9F (63 5C) during the light-on-without-water-spray period of the test cycle and the equilibrium relative humidity of the air in the test chamber shall be 50 5 %. The chamber temperature shall be 90 5F (32 3C) during the light-off-with-water-spiay period of the test and the relative humidity of the air shall be 95 5 %.
7.3 The water from the rack spray shall strike the back of the test specimens so that the only water on the face of the panels is from the dew formation caused by the chilled water on the back of the panels. The temperature of the water shall be 45 4F (7.2 2C). The water should have less than 20 ppm of solids.
7.4 Operate the apparatus on a cycle of 60 min dark with water-back spray and 60 min light without water spray/
8. Periods of Exposure
8.1 Use one of the following methods to determine the j duration of the exposure under this practice:
8.1.1 A mutually agreed upon specified number of total hours (light and dark hours),
8.1.2 Number of total hours of exposure required to produce a mutually agreed upon amount of change in either j the test specimen or an agreed upon standard sample.
9. Evaluation of Results
9.1 Evaluate conditions of exposed test specimens bj

Designation: D 3363 -74 (Reapproved 1989)1
Standard Test Method for Film Hardness by Pencil Test1
This standard is issued under the fixed designation D 3363; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
" N' --Sections 2 and 3 were editorially renumbered in March 1989.
1. Scope
1.1 This test method covers a procedure for rapid, inex pensive determination of the film hardness of an organic coating on a substrate in terms of drawing leads or pencil leads of known hardness.
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.
2. Summary of Test Method
2.1 A coated panel is placed on a firm horizontal surface. The pencil is held firmly against the film at a 45 angle (point away from the operator) and pushed away from the operator in a `A-in. (6.5-mm) stroke. The process is started with the hardest pencil and continued down the scale of hardness to either of two end points: one, the pencil that will not cut into or gouge the film (pencil hardness), or two, the pencil that will not scratch the film (scratch hardness).
3. Significance and Use
3.1 This test method is especially useful in developmental work and in production control testing in a single laboratory. It should be recognized that the results obtained may vary between different operators and laboratories. Every effort should be made to standardize the hardness of the lead used and the technique followed. If used as a basis for purchase agreement, this test method will achieve maximum precision if a given set of referee pencils be agreed upon between the purchaser and the seller.
4. Apparatus
4.1 A set of calibrated drawing leads (preferred) or equiv alent calibrated wood pencils meeting the following scale of hardness:2
1 This method is under the jurisdiction of ASTM Committee D-1 on Paint and Related Coatings and Materials and is the direct responsibility of Subcommittee DO 1.23 on Physical Properties of Applied Paint Films.
Current edition approved Oct. 25, 1974. Published November 1974. 1 Pencils from many manufacturers have been and may be used in pencil hardness testing but it was apparent to the test group (D01.53.02) that the leads supplied by two manufacturers were more uniform, and reproducible results could be obtained from batch to batch of leads. These are Microtomic, manufactured by Faber Castell, 551 Spring Place Rd,, Lewisburg,TN 37091, aadTurquoiss-T2375, manufactured by Mohawk, Route #30, Perth Road, Amsterdam, NY 12010.

The difference between two adjacent leads shall be consid ered one unit of hardness.
4.2 Mechanical Lead Holder, for drawing leads if used.3 4.3 Mechanical Sharpener, draftsman-type, is helpful for I trimming wood pencils if used.4 4.4 Abrasive Paper, grit No. 400.
5. Test Specimens and Conditions
5.1 Apply the surface coating by appropriate means to a I smooth rigid substrate and cure properly, or use representa- j tive panels cut from coated stock. The panels used, the I curing conditions, and the age of the coating prior to the testJ shall be within the limits agreed upon between the purchaser | and the seller.
5.2 The film thickness of the coating shall be as specified j or as agreed upon between the purchaser and the seller.
5.3 Conduct the test at 77 3.5F (25 2C) and 50 j 5 % relative humidity.
6. Procedure
6.1 For wood pencils, remove approximately 3/i6 to >/ in. j (5 to 6 mm) of wood from the point of each pencil using a I draftsman-type mechanical sharpener, being careful to leave 1 an undisturbed, unmarked, smooth cylinder of lead. Holding the pencil or lead holder (when using drawing leads) at an angle of 90' to the abrasive paper, rub the lead against the paper maintaining an exact angle of 90 to the abrasive paper until a flat, smooth and circular cross section is obtained, free of chips or nicks in the edge of the cross section. The desired edge may be attained by cementing the abrasive paper to a flat motor-driven disk. By supporting the pencil at | 90' to the rotating disk a uniform flat lead end may be| obtained more reproducibly.5
6.2 Place the coated panel on a level, firm, horizontal! surface. Starting with the hardest lead, hold the pencil or lead ! holder firmly with the lead against the film at a 45' angle! (point away from the operator) and push away from thef operator. Exert sufficient uniform pressure downward andl forward either to cut or scratch the film or to crumble the j
3 Turquoise No. 10 is the preferred holder, however, any holder adequately j
constructed to eliminate lead slippage may be used.
4 Dexter Super 10 Draftsman Type AI0D Cutter Assembly, manufactured byf
Apsco Products, Inc., or equivalent, has been found suitable.

ncil is found that will not cut through the film to the substrate (either metal or a previous coat) for a distance of at least '/ in. (3 mm) (see 7.1.1).
N' 1--The operator must watch closely for cutting into or
watching the film. Some finishes contain compounds that may tend to fabricate the film. Checks should be made by close visual inspection and m fingernail feel.
N' 2--In conducting the test, ifthe sharp edge ofthe lead is slightly
^pped or crumbled, the lead must be resharpened.
6.4 Continue the process until a pencil is found that will neither cut through nor scratch the surface of the film. Any defacement of the film other than a cut (gouge) is considered a scratch. Record each end point (ifapplicable) for gouge and scratch hardness (see 7.1).
N' 3--With some films, the two end points will be identical.
6.5 Make a minimum of two determinations for gouge hardness (6.3) and scratch hardness (6.4) for each pencil of lead.
7. Report
7.1 Report the following information: 7.1.1 The two end points as follows: 7.1.1.1 Gouge Hardness--The hardest pencil that will
leave the film uncut for a stroke length of at least Vs in. (3 mm).
7.1.1.2 Scratch Hardness--The hardest pencil that will not rupture or scratch the film.
7.1.2 The make and grade of lead or pencil used, and 7.1.3 Any deviation from standard conditions, including roughness in the finish.
8. Precision
8.1 In an interlaboratory test of this test method with three different films on panels, ten laboratories and opera tors, and repeated by switching leads and panels between laboratories, the within-laboratory standard deviation was found to be 0.52 and the between-laboratory standard deviation was found to be 0.61. Based on these standard deviations, the following criteria should be used for judging the acceptability of results at a 95 % confidence level:
8.1.1 Repeatability--Two results obtained by two opera tors within a laboratory using the same pencils and panels should be considered suspect if they differ by more than one pencil unit on the scale described in 4.1.
8.1.2 Operator Reproducibility--Two results, each the mean of at least two determinations, obtained by operators in different laboratories using the same pencils and panels or different pencils with the same panels should be considered suspect if they differ by more than one pencil unit on the scale described in 4.1.

tion, skinning, or other undesirable effects in the coating. Determine the condition of the coating in accordance with 6.1 and 6.2.
5.2 Sample in accordance with 4.2.1 of Method 1021 of U.S. Federal Test Method Standard No. 141. Determine the weight per gallon in accordance with Test Method D 1475. Repeat this procedure until successive readings agree within 0.1 lb (45 g) or as agreed upon between the purchaser and the seller. Samples for testing may then be taken.
5.3 Specify the amount of sample, the package sizes, and identification codes to assure a representative sample. A 1-gal (4-L) sample is usually sufficient for the recommended tests, but for guidance in selecting a sampling plan consult Recommended Practice E 105.
6. Liquid Paint Properties
6.1 Skinning--Coatings containing a binder that dries by oxidation may be subject to skin formation in a partially filled can. Since skins are insoluble in the material, they must be removed before use. The referenced test method indicates the tendency of a paint to skin. Examine the original sample for skins, both on the surface and in its mass. On a well-mixed, skin-free portion of the sample, perform a skinning test in accordance with Guide D 154.
6.2 Condition in Container--Thickening, settling, and separation are undesirable and objectionable if a paint cannot be reconditioned and made suitable for application
with a reasonable amount of stirring. The referenced method covers procedures for determining changes in properties of paints after storage. Determine the condition in the con tainer in accordance with Method 3011.1 of Federal Test Method Standard No. 141.
6.3 Coarse Particles and Foreign Matter--Paints must be free of coarse particles to form uniform films of good appearance, typical maximum being I weight % of total paint. The specified test with a No. 325 (45-gim) screen gives the percent of these particles in a paint. Determine coarse particles and foreign matter in accordance with Test Methods D 185.
6.4 Density or Weight per Gallon--The density as mea sured by weight per gallon or kilogram per litre is used to assure product uniformity from batch to batch. In the referenced test method, the density is expressed as the weight in pounds avoirdupois of 1 U. S. gal (kilogram/litre) of the paint at a specified temperature. A calibrated weight-pergallon cup is used. Determine density in accordance with Test Method D 1475.
6.5 Fineness ofDispersion--The more finely a pigment is
dispersed, the more efficiently it is being used. One method for measuring the degree of dispersion (commonly referred to as "fineness of grind") is to draw the material down a calibrated, tapered groove in a hardened steel block with the groove varying in depth from 4 to 0 mils (100 to 0 pm).

jiates, or both, protrude through the surface of the liquid is taken as the fineness reading, Lower readings in mils or micrometres or higher readings in Hegman units indicate better fineness of dispersion. Determine fineness of disper sion in accordance with Test Method D 1210.
6.6 Consistency--Consistency is important, relating to application and flow, and should fall within a range agreed upon. In the referenced test method, consistency is defined as the load in grams required to produce a specified rate of shear. Determine consistency in accordance with Test Method D 562.
6.7 Absorption--The referenced method provides a rapid determination of the relative penetration of the binder into a porous surface. It provides a rough measure of the wetting and penetrating properties of liquid materials. Loss of binder and the resultant change in pigment volume concentration as the film dries, are indicated by the test. Determine absorption in accordance with Method 4421 of Federal Test Method Standard No. 141.
6.8 Flash Point--When the flash point of a material is required for shipping information, use Test Methods D 93, Part B, or D 3278.
7. Paint Application and Film Formation
7.1 Application of Brushed Films--Brushed films should be smooth and free from seeds, color streaking, and brush marks. Test application ofa brushed film in accordance with Method 2141.1 of Federal Test Method Standard No. 141.
7.2 Brushing Properties--The specified method covers a means for determining the brushing properties of coatings. The test is quite subjective; however, someone experienced in the art can produce quite consistent results, particularly in the determination of "drag" qualities. Floor paints are generally applied to horizontal surfaces but evaluation on vertical surfaces may be necessary to determine performance on stair risers, railings, posts, etc. Determine the brushing properties in accordance with Method 4321.1 of Federal Test Method Standard No. 141.
7.3 Roller Coating Properties--Floor enamels are fre quently applied by roller. The referenced method outlines a procedure for making an evaluation of a material's charac teristics when applied by a roller. Determine roller coating properties in accordance with Method 4335 of Federal Test Method Standard No. 141.
7.4 Drying Properties--The drying time of a floor paint is important in determining when a freshly painted floor or stair may be subjected to traffic. Slow drying of the film may result in dust pickup, poor appearance, and, if used on an exterior surface, rain or dew may cause a nonuniform appearance. The test can also be used to determine whether or not the drying properties of the paint have changed during storage in the container. Determine drying time in accord ance with Test Method D 1640.
7.5 Leveling Properties--Leveling is an important factor when uniform surfaces are to be produced, as it affects hiding and appearance. The referenced test method covers the laboratory determination of the relative leveling characteris tics of liquid coatings. Determine leveling characteristics in accordance with Test Method D 2801.
7.6 Producing Films of Uniform Thickness--The fol lowing test method covers the preparation of various films of
uniform thickness essential in conducting tests. Prepare films in accordance with Test Methods D 823.
8. Appearance of The Dry Film
8.1 Color Differences of Opaque Materials by Visual Evaluation--Visual comparison of color is fast and often acceptable although numerical values are not obtained. The referenced method covers the spectral, photometric, and geometric characteristics of light source, illuminating and viewing conditions, size of specimens, and general proce dures to be used in the visual evaluation of color differences of opaque materials. Determine color difference in accord ance with Practice D 1729.
8.2 Color Differences of Opaque Materials by Instru mental Evaluation--Color difference between a product and the standard can be measured by instrument. Generally the tolerance is agreed upon between the purchaser and the seller. The referenced method covers the instrumental deter mination of small color differences, observable in daylight illumination, between nonfluorescent, nonmetameric, opaque surfaces such as paint specimens. If metamerism is suspected, visual evaluation (8.1) should be used to verify instrumental results. Conduct instrumental evaluation of color difference in accordance with Method D 2244.
8.3 Gloss--Floor enamels generally have a high initial 60-deg gloss reading when first applied. Determine the specular gloss in accordance with Test Methods D 523 or D 1471.
8.4 Hiding Power (Dry Opacity)--Hiding power is the measure of the ability of a paint to hide the substrate. It is, however, dependent upon uniform film thickness which is influenced by flow and leveling. Test Method D 344 is a practical test in which paint is applied with a brush, film thickness is approximately measured, opacity is evaluated visually as compared to a standard paint, and results are affected by flow and leveling application properties of the paint. Test Method D 2805 is considered to be a more precise and accurate test which does not need a material paint standard. Paint is applied with an applicator bar to minimize the effects of flow and leveling, film thickness is rigorously measured, and opacity is instrumentally evalu ated. Determine hiding power in accordance with Test Methods D 344 or D 2805.
9. Properties of the Dry Film
9.1 Abrasion Resistance--Abrasion resistance is a mea sure of the ability ofa dried film to withstand wear from foot traffic and marring from objects rolled or pulled across the surface. Determine abrasion resistance in accordance with Test Methods D 658 or D 968.
9.2 Elongation--Elongation is a measure of the flexibility of paint films. Determining elongation in accordance with Test Methods D 1737 or D 522.
9.3 Adhesion--Adhesion is the property of the film which resists removal from the substrate when scuffed or scraped. It is an important property in a floor paint. Determine adhe sion in accordance with Test Methods D 2197.
9.4 Resistance to Chemicals--An important property of a floor paint is its ability to resist spotting, softening, or removal when subjected to household chemicals or strong
489

# 0 3383
cleaners. Determine resistance to chemicals'in accordance with Test Method D 1308.
9.5 Exterior Exposure--If the paint is intended for use on porches, decks, or outside stairways and railings, tests for resistance to exterior exposure may be required.
9.5.1 Conducting Exterior Exposures--In conducting ex terior exposures, refer to Practice D 1006 or Test Method D 1014.
9.5.2 Wood Panel Description--In establishing exposure performance, use die panels as described in Specification D358.
9.5.3 Chalk Resistance--Determine the chalk-resistance rating by reference to Method D 659.
9.5.4 Checking Resistance--Determine the checking re sistance rating by reference to Test Method D 660.
9.5.5 Cracking Resistance--Determine the cracking re sistance rating by reference to Test Method D 661.
9.5.6 Erosion Resistance--Determine the erosion resist ance rating by reference to Test Method D 662.
9.5.7 Flaking Resistance--Determine the flaking resist ance rating by reference to Test Method D 772.
10. Analysis of Paint
10.1 Chemical Analysis--If a specification requires cer tain raw materials or certain components in a given amount then chemical analysis is required. Chemical analysis deter mines whether the specified components are present and if they are, in what amounts. It does not necessarily establish
paint quality which can also be greatly affected by manufao. turing techniques. No single schematic analysis is compre. hensive enough to cover the wide variety of floor enamej composition.
10.2 Volatile Content--The percent of volatile matte, indicates the thinner loss from the film as it dries. This quantity subtracted from 100 % gives the nonvolatile con. tent Determine the volatile content in accordance with Test Method D 2369.
10.3 Pigment Content--Pigment gives the hiding and color and influences many other properties of a coating.
Determine the percent pigment in accordance with Test Method D 2371.
10.4 Pigment Analysis--The analysis of pigment maybe required ifthe product is covered by a specification, or if it is agreed between the purchaser and the seller. Analyze the pigment in accordance with selected test procedures from Method D 215 and other appropriate ASTM Test methods.
10.5 Identification of Vehicle Solids--The type of nonvolatile vehicle used in a coating has a great influence on its properties. The referenced test method gives a procedure for identifying the main components of the binder. Determine the identity of the vehicle solids in accordance with Method D 2621.
10.6 Identification of Oils--The composition of the non volatile vehicle can, if desired, be further broken down into the types of oils present. Determine the identity of oils in accordance with Method D 2245.

4, Liquid Enamel Properties
6.1 Skinning--Enamels containing a binder, that dries by oxidation may be subject to skin formation in a partially jOed can or by diffusion of air into a filled can. Since skins jte insoluble in the enamel, they must be removed before ose. This test in a partially filled container indicates the tendency of an enamel to skin. A typical minimum time for sinning in accordance with the referenced test method is 48 jt. Examine the original sample for skins, both on the surface and in its mass. On a well-mixed, skin-free portion of the sample, perform a skinning test in accordance with Guide'
0154. 6.2 Condition in Container--Thickening, settling, and
separation are undesirable and objectionable if an enamel, i after storage, cannot be readily reconditioned and made ! suitable for application with a reasonable amount of stirring, j The referenced method covers procedures for determining j changes in properties after storage. Determine the condition
in the container in accordance with Method 3011.1 of Federal Test Method Standard No. 14 L.
6.3 Coarse Particles and Foreign Matter--Enamels must be free of oversize particles and foreign matter to form a uniform film of good appearance, a typical maximum being 0.5 weight % of total enamel. The specified test with a No. 325 (45-pm) screen gives the percent of these particles in an enamel. Determine coarse particles and foreign matter in ; accordance with Test Method D 185.
6.4 Weight per Gallon--The density of an enamel as measured by weight per gallon (or kilograms per litre) is used to assure product uniformity from batch to batch and provides a check against the theoretical weight calculated ; from the formula. The referenced test method gives a procedure for measurement of the density ofan enamel. The density is expressed as weight in pounds of 1 U.S. gal (kilograms per litre) of the enamel at a specified temperature. | A calibrated weight-per-gallon cup is used. Determine weight | per gallon in accordance with Test Method D 1475.
6.5 Fineness of Dispersion--One method for measuring ; the degree of dispersion is to draw the enamel down in a
tapered groove in a hardened steel block with the groove varying in depth from 4 to 0 mils (100 to 0 pm). The point at which continuous groupings of particles or agglomerates, or both, protrude through the surface of the wet film is taken as the fineness reading. Lower readings in mils or micrometres ; or higher readings in Hegman units indicate better disper-
! don. A typical fineness of dispersion requirement is a j leading of 1.0 mil (25 pm) or 6 Hegman for interior j semigloss wall and trim enamels. Determine fineness of i dispersion in accordance with Test Method D 1210,
6.6 Odor--Some solvent combinations produce obnox` bus odors, particularly when painting indoors with inade-
s
quate ventilation and under advene temperature-humidity conditions. Test for odor in accordance with Method 4401 of Federal Test Method Standard No. 141.
6.7 Consistency--Enamels of a given type should fall within a consistency range agreed upon. In the referenced test method, consistency is defined as the load in grams required to produce a specified rate of shear. Enamels for professional painters are usually formulated at a higher consistency range than consumer enamels. A typical range is 75 to 90-Krebs unit (KU) foi consumer enamels and 90 to 100 KU for professional painter enamels. Determine the consistency of the product in accordance with Test Method D 562.
6.8 Rheological Properties of Non-Newtonian Liquids-- Rheological properties are related to the application and flow properties of the liquid coating.

In fact, viscosity under varying conditions of time and rotational speed of the spindle is measured. Determine the rheological properties in accordance with Test Method D 2196.
6.9 Dilution Stability--The diluent suggested for reduc tion should be readily incorporated into the enamel without excessive stirring or shaking. This, test is a measure of the stability of an enamel that has been reduced to a desired viscosity, for example, for spray application. Determine dilution stability in accordance with Method 4203 of Federal Test Method Standard No. 141.
6.10 Absorption--The referenced method provides a rapid means for measuring the relative penetration of the binder into a porous surface. It provides a rough measure of the wetting and penetrating quality of liquid materials. Lass of binder and the resultant change in pigment volume concentration, as the film dries, are indicated by this test. Determine the absorption in accordance with Method 4421 of Federal Test Method Standard No. 141.
6.11 Flash Point--Organic solvents used in enamels have characteristic temperatures at which they will support com bustion. This temperature is known as the flash point. It is often used for danger classification in shipment by common carriers. It is also used to determine conditions of storage to meet fire regulations and also the safety requirements of the Occupational Safety and Health Act (OSHA). Determine the flash point in accordance with Test Methods D93 or D 3278. .
6.12 Color Compatibility--If tinting colors are not ade quately compatible with enamel tint base, lighter, darker, or nonuniform shades of color will develop. Tintability of white bases with colorants of standardized tinting strength is a trade requirement. The test method shall be agreed upon between the purchaser and the seller. An ASTM test method is now being developed.
7. Enamel Application and Film Formation
7.1 Application by Brush--Brushed films should be smooth and free of seeds and on vertical surfaces should show no sagging, color streaking, or excessive brush marks. Test application-of brushed films in accordance with Method 2141.1 of Federal Test Method Standard No. 141.

N' 1--When a referee test is made, prepare fresh medium or use
standardized scrub medium11 from a previously unopened container that is no more than 1 year old.
8. Preparation of Apparatus
8.1 Washability Machine--The washability machine should be leveled before use and operated at 37 1 cpm; each cycle consisting of a complete forward and reverse stroke. Adjust tautness of the cables with a spring scale to approximately 5 lb.
8.2 Sponge and Holder--Add sufficient weight to the holder in the form of lead sheets or other flat weights to give a combined weight of 1500 g, including the dry sponge.
N !' 2--Check the compression of the damp sponge under the 1500-g weight to ensure that the holder does not drag along the panel
and tear the film.
9. Procedure
9.1 Clean the top of the glass plate (or preferably the suction plate) and both sides of the black plastic panel to be sure they are free of specks. Place the black panel on the plate and tape one end to the plate. Smooth the panel along the plate to ensure a close fit.
9.2 Stir the test material thoroughly and strain to remove all skins and particles. Draw down the material on the panel, starting from the taped end of the panel. For latex paints, the 10-mil (0.25-mm) side of the applicate will generally be satisfactory, whereas the 7-mil (0.18-mm) side can be used for solvent-based coatings. However, the film thickness of paint to be applied may be varied as mutually agreed upon between the purchaser and the seller. The rate of application should be fairly slow, 3 to 4 s from end to end, to prevent

pinholes or holidays in the film. Air dry in a horizontal
position for 7 days in a room preferably maintained at 73.5 3.5F (23 2C) and 50 5 % relative humidity, or under conditions mutually agreeable to the purchaser and the
seller. 9.3 On the last day of drying, measure the directional
reflectance (green filter) of a portion of the panel in accordance with Test Method E 97. Record this value as R
9.4 After reading the reflectance, use the applicator with the 3-mil (76-p.m) clearance to draw down a film of soilant medium perpendicular to the coating film and in the area where the reflectance was measured. Permit the stained panel to dry for 16 to 24 h under the same drying conditions specified in 9,2.
9.5 Clean the glass surface on which the test panel is to be mounted and also the back of the test panel. Attach the test panel to the glass plate and place the mounted test panel, coated side up, in the pan. Clamp the assembly securely to the pan with the "C" clamps, centering the pan so that the sponge boat can move lengthwise on the panel.
9.6 Remove the sponge from the holder and soak it in reagent water at room temperature. Remove the sponge and squeeze repeatedly with one hand until no more water drips from the sponge. Replace the sponge in the holder and pour 15 1 mL of water on the exposed face of the sponge. Stir the scrub medium and spread uniformly across the face of the sponge 10.0 0.1 g of nonabrasive scrub medium. (Use a spatula if necessary, when applying the abrasive scrub medium, to apply uniformly over the sponge.)
9.7 Attach the sponge holder, with the sponge and cleaner face down, to the cables of the washability machine. Add 5 mL of water on each side of the holder in the path of the sponge. Start the motor and allow the sponge to travel 25 cycles at the rate of 37 1 cpm. Ensure that the sponge and holder are level during the run, otherwise uneven wear will occur on the test panel. At the end of 25 cycles, stop the machine, remove the sponge, clean in running water, sqeeze dry, and resoak in water. Wipe off excess stain outside the test area. Repeat the procedure starting in 9.6 with "remove the sponge and squeeze it repeatedly........" for an additional 25 cycles. Repeat the 25-cycle procedure for a total of 100 cycles, each time trying to start and stop the sponge outside the stained area of the panel.
9.8 Remove the test panel from the pan, rinse with running tap water, gently moving the palm of the hand ovj
the path of the sponge to remove clinging particles of scrub medium. Blot the panel and then allow to dry at room temperature. After the panel has dried thoroughly, wipe off excess stain outside the test area and measure reflectance m the soiled and washed area of the panel. Record as R2.
9.9 Repeat the test on a second panel and, for each calculate the reflectance recovery in percent as (RJR,} v
100.
9.10 If the mean reflectance recovery for the two panels is less than 96 %, repeat the test on another set of panels using the abrasive scrub medium specified in 7.7.2 and report the results with both mediums.
10. Report
10.1 Report the mean of the two determinations and the type of scrub medium used.
10.2 Report any deviations from the standard procedure. 10.3 Note if erosion occurred in the soiled area.
11. Precision and Bias
11.1 On the basis of an interlaboratory study in which operators in six laboratories tested six coatings, including solvent and water-based systems, and covering a range of pigment volume concentrations (PVC's), the following cri teria should be used for judging the acceptability of the results at the 95 % confidence level:
11.1.1 Repeatability--Two results obtained by the same operator should be considered suspect if they differ by more than 1.5 % in reflectance recovery with the abrasive cleaner and 9 % in reflectance recovery with the nonabrasive cleaner.
11.1.2 Reproducibility--Two results, each the mean oftwo measurements, obtained by operators in different labo ratories should be considered suspect if they differ by more than 6 % in reflectance recovery with the abrasive cleaner and 25 % with the nonabrasive cleaner.
11.2 Bias--The concept of bias is not applicable to this test method.

POLYMERIC POWDER PROPERTIES
8. Particle Size and Distribution
8.1 Multiple Sieve Analysis: 8.1.1 This method employs multiple sieves to determine particle sizes and their distribution. Standard 200-mm(8-in.) diameter sieves and a mechanical shaker are used. A representative quantity of the sample is sifted through a series of sieves and the amount retained on each sieve is weighed and calculated as percent of the total specimen. 8.1.2 Apparatus: 8.1.2.1 Sieves--Half-height sieves, 200 mm (8 in.) in diameter, conforming to the requirements of Specification E 11. A selection of sieves encompassing the expected range of particle sizes together with a cover and a bottom pan are required. 8.1.2.2 Mechanical Sieve Shaker with Automatic Time Switch13--The mechanical sieve-shaking device shall be ca pable of imparting uniform rotary motion and a tapping action at the rate of 150 10 taps/min. 8.1.2.3 Balance--A laboratory balance with a minimum capacity of500 g sensitive to 0.1 g, for weighing the specimen and the residues retained on the sieves. 8.1.3 Procedure: 8.1.3.1 If the residues are not to be transferred for weighing, weigh each of the selected sieves and the bottom pan to 0.1 g. Nest the desired sieves in order of diminishing openings with the coarsest sieve on top and the pan on the bottom.
13 Ro-Tap Sieve Shaker has been found suitable for this purpose and is available from W. S. Tyler Co., Cleveland, Ohio 44114. An equivalent may be used.

8 13.2 Weigh out a 100 0.1-g specimen and transfer it
to the top sieve of the stack.
N' i--if necessary this test may be made on a specimen of any
size from 50 to 200 g. The weight of specimen used shall be stated in the
report.
8.1.3.3 Place the cover on the top sieve, and place the stack in the mechanical sieve shaker. Operate the shaker for 10 min 15 s.
8.1.3.4 After shaking, carefully separate the stack of sieves, beginning at the top, and weigh the quantity of material retained on each sieve and that contained in the pan to 0.1 g. This may be accomplished either by transferring the fractions to the balance or by weighing the sieve or pan and its contents, and subtracting the tare weight from the total. If the material is transferred to the balance, carefully brush the sieve on both sides to ensure that adhering particles are transferred.
8.1.3.5 Calculate the percent in each fraction as follows:
% = {R/S) x 100
where: R = residue weight, g, and S = specimen weight, g.
N' 2--Ordinarily there is a small loss of dust as indicated by the
cumulative total weight being less than 100 %. If this loss is not over 2 %, the amount reported through the finest sieve shall be increased until the total of all portions of the sample equals 100%. If the cumulative total is less than 98 %, repeat the test.
8.1.4 Report--The report shall include the following: 8.1.4.1 Complete identification of the sample, 8.1.4.2 Specimen weight, 8.1.4.3 Percent of material retained on each sieve, 8.1.4.4 If required, the total cumulative percent of mate rial retained on each sieve and in the pan, 8.1.4.5 Temperature, and 8.1.4.6 Relative humidity. 8.2 Vacuum Sieve Analysis: 8.2.1 Summary ofMethod: 8.2.1.1 In this method sieving is accomplished by aerody namics so that there is no reduction in particle size and absolutely no wear on the sieves. 8.2.1.2 The housing holds a standard 200-mm (8-in.) sieve and a transparent sieve cover. A slit nozzle rotates slowly below the sieve. An air current, produced by a standard vacuum cleaner-type device, is blown upwards through a hollow shaft and the slit nozzle to the sieve, where it clears the screen. The particles thus suspended in air between the sieve and the sieve cover are separated as the air current circulates. The line materials are blown through the sieve and into a filter bag, while the coarse materials remain on top of the sieve. A manometer indicates the vacuum inside the housing. 8.2.2 Apparatus: 8.2.2.1 Sieves--As described in 8.1.2.1 and transparent sieve cover. 8.2.2.2 Vacuum Sieve Apparatus--A vacuum sieving device14 capable of maintaining inside the housing a vacuum
of 5 0.5 in. (127 12.7 mm) of water as measured by a
manometer. The slit nozzle which rotates below the sieve shall revolve at a speed of 25 2 rpm.
8.2.2.3 Balance--See8.1.2.3. 8.2.3 Procedure:
8.2.3.1 If the residues are not to be transferred for weighing, weigh each of the selected sieves to 0.1 g.
5.2.3.2 Weigh out a 100 + 0.1 g specimen and transfer it to one of the sieves.
N' 3--If necessary, this test may be made on a specimen of any
size from 10 to 50 g. The weight of specimen used shall be stated in the
report. For small sieve openings, I to 10 g is recommended.
8.2.3.3 Place the transparent cover on the sieve and place the sieve in position on the vacuum sieving apparatus. Operate the sieving apparatus for 5 min 15 s at a vacuum of 5 0.5 in. (127 12.7 mm) of water.
8.2.3.4 Remove the sieve and cover from the apparatus and weigh the quantity of material retained on the sieve and adhering to the cover to the nearest 0.1 g. This may be accomplished either by transferring the retained material to the balance or by weighing the sieve, cover, and contents, and subtracting the tare weight from the total. If the material is transferred to the balance carefully brush the sieve on both
sides, and removed all powder from the cover to ensure that all adhering particles are transferred.
8.2.3.5 Repeat the procedure for each sieve used. 8.2.4 Calculate the percent retained on each sieve as follows:
% -= (R/S) x 100
: I i !
I
1
where:
R -- residue weight, g, and
5 = specimen weight, g.
8.2.5 Report--The report shall include the following:
8.2.5.1 Complete identification of the sample,
8.2.5.2 Specimen weight,
8.2.5.3 Percent of material retained on each sieve,
8.2.5.4 Temperature, and
8.2.5.5 Relative humidity.
8.3 Sonic Sifter Analysis:
8.3.1 Summary ofMethod:
8.3.1.1 In the sonic sifter, the sieves are stationary and
agitation is imparted to the particles by an oscillating column
of air. Sieve wear and particle attrition are minimal.
8.3.1.2 The sonic sifter consists of a sieving chamber, a
diaphragm at the top vibrating at 60 Hz, and a motor with
the necessary controls. The amplitude of vibration is adjust
able to the nature of the specimen.

Set the sift amplitude at 3 and the pulse amplitude at 10. Operate the sifter for 3 min 15 s. 8.33.5 Weigh each sieve, the fines collector, cover, and the collar, subtract the tare weight for each, and calculate the percent retained on each sieve.
N' 4--Include any material adhering to the cover and the collar in
pie weights for the top sieve.
8.3.4 Report--The report shall include the following: 83.4.1 Complete identification of the sample,'
83.4.2 Specimen weight, 8.3.43 Percent of material retained on each sieve, 83.4.4 Temperature, and 83.4.5 Relative humidity. 8.4 Electronic Counting Analysis: 8.4.1 Summary ofMethod: \ 8.4.1.1 This method, one of several found valuable for the measurement of particle size, covers the determination ofthe particle size distribution of powder coatings (0.6 to 80.0 pm) using the electronic particle counter.16 This instrument uses an electric current path of small dimensions which is modulated by individual particle passage through an aper ture, and produces individual pulses of amplitude propor tional to the particle volume. 8.4.1.2 The powder is carefully dispersed ultrasonically or by some other appropriate method and a portion is added to a filtered electrolyte. Particle counts are obtained at several selected particle size levels and converted to relative weight fractions assuming constant particle density. 8.4.13 The instrument response is essentially to particle volume (liquid displacement); therefore equivalent spherical diameter is commonly used to express the particle size. 8.4.2 Apparatus: 8.4.2.1 Electronic Particle Counter,16 detecting particles using electric current through a liquid resistor. 8.4.2.2 Aperture Tube, 200-gm diameter. The diameter required is dependent upon the particle size distribution of the sample. Generally any given tube will cover a particle size range from 2 to 40 % of its aperture diameter. 8.4.23 Beaker, 250 to 500-ml, capable of maintaining all particles uniformly in suspension (for example, baffled or round bottom). 8.4.2.4 Ultrasonic Agitator. | 8.4.2.5 Membrane Filtering Device, 0.45-pm filters.17 | 8.4.3 Reagents: j 8.43.1 Purity of Reagents--Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications
of the committee on Analytical Reagents of the American Chemical Society, where such specifications are available.18 Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination.
8.43.2 Purity of Water--Unless otherwise indicated, ref erences to water shall be understood to mean reagent water conforming to Type IT of Specification D 1193.
8.4.33 Dispersing Medium--5 % solution of octyl phenoxy polyethoxyethanol19 in reagent water.
5.4.3.4 Electrolyte--Dissolve 10.0 g of reagent grade so dium chloride (NaCl) in 1000 ml of reagent water, add some bacteriacide such as 70 mg of sodium trichlorophenate then filter twice through the membrane (8.4.2.5).
8.43.5 Wash Water--Reagent water filtered twice. 8.4.4 Procedure: 8.4.4.1 Precalibrate the aperture and electrolyte combina tion following the manufacturer's instruction manual.
N' 5--Calibration should be carried out using a lycopodium of
microspheres suspension of IS.04-p.m diameter with the half-count procedure as given in the instruction manual. It is necessary to have mutual agreement on monosized system diameters for interlaboratory comparisons.
8.4.4.2 Cone and quarter the sample until a specimen of convenient size is obtained.
8.4.43 Disperse the specimen by adding dispersing me dium from the eye-dropper. Use gentle spatulation until a pasty consistency is obtained. Pick up a small portion of this mixture (about 0.1 ml more or less depending on the particle size of the powder) on a small spatula and rinse with wash water into a 25-ml beaker containing 5 ml of dispersing medium. Place the beaker in the ultrasonic agitator for 30 s and then rinse into 200 ml of electrolyte in the 250 to 500-ml beaker. Fill the beaker to capacity and place in the counting position of the counter stand.
8.4.4.4 Fill the aperture tube with electrolyte. Check the aperture for blockage and clear with a brush if necessary. Set the instrument controls for the smallest particle appropriate for the aperture in use. Typical instrument settings are shown in Figs. 1, 2, or 3'.
8.4.4.5 Take three cumulative counts with 500-pi volume manometer and calculate the mean, which should be be tween 2700 and 5000. If it is not, adjust the particle concentration until it is. If more powder is added, it must be treated the same as the original specimen, except it may be rinsed directly into the beaker after ultrasonic agitation. If the suspension needs dilution, drain some of the suspension through a clean glass tube while agitating and then refill the beaker with electrolyte.
8.4.4.6 Set the instrument controls for normal accumula tion of differential data. Typical instrument settings are shown in Figs. I, 2, and 3. Take three counts at each size level for averaging.

8.4.5 Precautions: 8.4.5.1 Check the aperture for blockage at the end ofeach count. If blocked clear the aperture with the brush and retake
the count. 8.4.5.2 Adjust the sample stand stirrer motor speed to
furnish sufficient agitation to maintain a uniform particle suspension but below air bubble generation speeds.
8.4.5.3 Before each analysis flush all the surfaces coming in contact with the specimen. Use clean wash water and
wash bottle. 8.4.6 Treatment ofResult: 8.4.6.1 The values obtained in 8.4.4.6 represent relative
volume ofthe particles between two particle size levels. They may be plotted directly on semilog graph paper as a histogram (see Fig. 4).
8.4.6.2 The values obtained in 8.4.4.6 may be added cumulatively. All of these cumulative values may then be normalized to 100 % and a cumulative volume percent curve drawn (see Fig. 4).
8.4.6.3 Relative volume and relative weight are inter changeable if a constant density of the particle system is assumed. Therefore, the curves in 8.4.6.1 and 8.4.6.2 can be
interpreted as weight histogram and weight percent curves.

APPLICATION PROPERTIES
19. Determining the Relative Deposition Efficiency of Or ganic Polymeric Powders on Moving Targets
19.1 Summary of Method--The method essentially con sists of spraying powder at a known flow rate on a number of similarly shaped targets moving at a known rate past a powder spraying device mounted in a spray booth.
19.2 Apparatus: 19.2.1 Set of Targets, consisting of 15 flat steel panels 6 by 36 by 0.063 in. (152 by 915 by 1.6 mm) wrapped in aluminum foil, (Use other targets as agreed upon between the purchaser and the seller.) The panels should have holes drilled at one end for hanging from a conveyor. The aluminum foil should be of the lowest possible temper and should be 13Vi by 37 by 0.0015 in. (340 by 940 by 0.04 mm) (these characteristics have been found to be the best for easy wrapping of the panels). Other tempers, thicknesses, and dimensions may be used, however (for example, regular commercial aluminum foil is satisfactory). 19.2.2 Fifteen Target Hangers constructed so that the targets will hang from the conveyor in one plane within Vi in. (13 mm) with the flat surfaces perpendicular to the source of the powder spray. The target hangers should be long enough so the source of the powder spray can be pointed at the center of the targets. 19.2.3 Powder Flowmeter, consisting of a vacuum cleaner attached to a small vacuum chamber (powder receiver) constructed as shown in Fig. 5. 19.2.4 Balance, sensitive to 100 mg. 19.2.5 Balance, sensitive to 1 mg. 19.2.6 Stop Watch, accurate and readable to Vs s. 19.2.7 Powder Spray System. 19.3 Procedure: 19.3.1 Cut the number of aluminum-foil wrappings nec essary for the desired number oftests and number (with a felt tip pen, grease pencil, etc.) on one comer. If the available balance can weigh the entire target, weigh the panels with the aluminum-foil wrappings. If the balance cannot weigh the entire target, weigh the aluminum-foil wrappings alone. Record the numbers and corresponding weights. 19.3.2 Wrap the targets with the foil. The best method of doing this is simply to lay the foil on a flat surface with the numbered side down. Place the target on the foil so that it is centered on the foil and Vz to 1 in. (13 to 25 mm) from the long edge of the foil. For convenience, the top of the target (where the hanger holes are) should be at the numbered end of the foil wrap. Fold the Vz to 1-in. (13 to 25-mm) piece of foil over the edge of the target, creasing it firmly. Then turn the panel over so that it wraps the foil around itself, and crease the new edge firmly. Then him the panel over again (this will fold the remaining foil over) and crease it firmly. 19.3.3 Determine the conveyor speed by measuring the distance between two points on the conveyor track at least 10 ft (3.05 m) apart and by measuring, with the stop watch, the time it takes a location on the conveyor chain to travel the distance between the two points. If possible, adjust the conveyor speed to as close to 10 ft/min as possible (2 %). 19.3.4 If possible, hang the 15 targets on the conveyor on 12 in. (305 mm) centers far enough ahead of the spray booth to allow the conveyor to come up to speed (at least 1 min
travel) or for this test, 10 ft (3.05 m).
19.3.5 Break up any powder agglomerates in the powder by mixing or sieving before adding to the powder hopper. Determine the powder flow by first weighing the vacuum cleaner bag with the balance and then installing it in the bag chamber. The vacuum cleaner bag alignment holes should go on the alignment pins on the bag chamber. Install the cover on the bag chamber (simply place on bag chamber). Start the vacuum cleaner and adjust the damper so that very little air is felt moving through the hole in the cover (vacuum in the vacuum bag should be 0.3 to 0.7 in. (8 to 17 mm) of water, vacuum in the flowmeter should be 1.5 to 2.5 in. (38 to 64 mm) of water).
19.3.6 Insert the powder spray device into the opening in the top of the powder flowmeter and turn on the dust collector. Turn on the powder spraying device for 30 or 60 s. (Caution--Be sure high voltage is turned off or, if that is not possible, at the lowest possible adjustment), measuring the time with the stop watch. Disassemble the powder flowmeter and reweigh the vacuum cleaner bag on the balance. The increase in weight divided by the time the powder was flowing is the rate of powder flow. The powder in the vacuum cleaner bag can be recovered simply by tearing the bag in half and dumping the powder in the booth or hopper.
19.3.7 Adjust the powder flow, if possible, to 300 g/min 5 % by successive process changes. Also adjust or record, or both, all the process variables possible including the fol lowing:
19.3.7.1 The powder and its state of use, 19.3.7.2 The particle size distribution if available, 19.3.7.3 The high-voltage power supply output potential and output current, 19.3.7.4 The resistor in the gun, 19.3.7.5 The potential of the powder gun's charging tip, 19.3.7.6 The distance between the target and the charging tip, 19.3.7.7 The pattern adjustment mechanism (measure such things as the relative locations of the parts), 19.3.7.8 The conveyor speed, 19.3.7.9 The powder flow, 19.3.7.10 The powder collector system air flow or some pressure which changes as a function of air flow only, 19.3.7.11 The powder transfer air flow and air pressure, 19.3.7.12 The powder quantity control pressure or what ever variable controls this, 19.3.7.13 For fluidized beds; air flow, air pressure, the amount of powder, and bed depth, 19.3.7.14 Other variables such as vortex air, dosing air, powder density air, pattern air, etc,.and 19.3.7.15 The atmospheric variables: temperature, baro metric pressure, and humidity. 19.3.8 Mount and level the powder spray device in the spray booth so that it is aimed at the centers of the targets as they pass. Position it so that its charging tip is 8 Vz in. (203 13 mm) from the plane in which the targets will pass. 19.3.9 Turn on the powder flow, adjust the high voltage to 60 1 kV (use other voltages as agreed upon between the purchaser and the seller), turn On the powder collection system, etc. Start the conveyor and spray the targets after all other systems seem to be operating normally and powder is spraying into the spray booth.

19.3.10 After spraying the targets, stop the conveyor and remove the targets, taking care not to knock or jar the powder off of them. If it is desired to cure the powder, place the targets in an oven for the time and temperature recom mended for the specific powder being used. If necessary, this is also an excellent time to determine the weight percent tetained after curing the powder. Weigh 1 g of powder in a preweighed 5-in. (127-mm) diameter aluminum foil "pan." place this in the oven along with the targets.
19.3.11 After curing, remove the targets from the oven and pull the aluminum foil down 1 to 2 ft (305 to 610 mm) as soon as possible using asbestos or thick workman's gloves, this facilitates the final removal of the aluminum foil because the coated foil tends to contract slightly with cooling and become very difficult to remove when cool enough to handle. If necessary, also remove the pan of powder from the oven. After they are reasonably cool, remove the aluminumfoil wrappings, if they are to be weighed alone.
19.3.12 Weigh the center 11 targets or aluminum wrap pings from the center 11 targets excluding the two targets on each end of the target set (The end targets are excluded because they tend to collect excessive amounts of powder relative to the other targets.) Determine the amount of powder added to each target. If necessary, weigh the pan of powder and determine the weight percent retained. If the powder was not cured, the targets may be blown off and then wiped off to prepare them for the next test.
19.3.13 Calculate the mean weight of powder deposited. Calculate the percent deposition efficiency using the fol lowing equation:
% E = (Wp x Vc x 10 000)/U)T xQpx% R)
where: % E -- percent deposition efficiency, Wp = mean powder deposition, g, Vc = conveyor speed cm/min, Dt = distance between target centers, cm, Qp = powder flow, g/min, and % R -- percent by weight powder retained after curing
(100 % if not cured). 19.3.14 To determine the variation in application of the coating, calculate the coefficient of variation using the following equation:
2 Wf - nWA1'2
n- 1 /
WP
where: F = coefficient of variation %, Wp - weight of powder on a foil wrapping, g, _ = number of targets used (11), and Wp = mean powder deposition, g.
19.3.14.1 If the coefficient of variation exceeds 10% it indicates that the powder cloud is fluctuating excessively. This is due usually to poor (slugging) powder pump opera tion, sometimes to unstable booth air flow profiles, and sometimes to unstable air flow patterns created by spray gun powder cloud control system.
19.3.15 Repeat the above procedure until two consecutive j results agree within 10 %. Use the set of conditions under
which these results were obtained as a standard to which to relate future work. It is wise to run the test within the standard conditions at the beginning and end of each day. If results do not agree within 10 % the day's work should be suspect. Results will vary from day to day and even during the day due to variables beyond the user's control. Long term variations can even be as large as 50 %. Tests run with different powders or under different conditions should have the results reported in terms of the standard test results. For example, if die efficiency results under the standard condi tions were 50 % with one powder and 75 % with another powder, the second powder would be 50 % more efficient than the first powder.
19.4 Report:
19.4.1 Report the variables and their values as recorded for 19.3.7. Report the percent deposition efficiency and its coefficient of variation, the percent efficiency compared to the average percent efficiency obtained using the standard conditions on the day of the test.
19.5 Precision--Deposition efficiency results should be repeatable within 10 % during a day.

33.1 While the accelerated tests given elsewhere in this recommended practice are intended to enable prediction of probable performance, actual outdoor exposures should be made on coatings intended for exterior use. Usage of paint systems is so varied that no one set of conditions (length or place of exposure) can be given in this practice to cover all situations. These conditions as well as the type of substrate, substrate preparation, etc., should be agreed upon between the purchaser and the seller. However, it is suggested that unless otherwise agreed upon, panels for outdoor exposure should be prepared in accordance with Section 19 of this practice.
33.2 Many properties of powder coating films should be evaluated periodically throughout the outdoor exposure period. These properties may be evaluated as follows:

Disfigurement of Paint Films by Microbial (Fungal or Algal) Growth or Soil and Dirt Accumulation2
3. Summary of Practice
3.1 Simple observation of a coated object subjected to exterior exposure is considered a practical and reliable method for determining the degree that microorganisms discolor the coating. However, this applies to a specific coated object exposed under a given set of conditions. It should be recognized that there are critical factors that influence the amount of fungal growth that may occur on the same coated object when exposed to other conditions. These factors include the geographic location, local atmospheric conditions such as the dust and pollen content of the air, angle of exposure, degree to which the coating is subjected to weathering, effects of moisture and sunlight, the substrates on which the coating is applied, and the coatings in the paint system under test. The latter factor includes the stability of the coating while packaged in the container, as well as the composition of the coatings included in the total system and

the thickness of each coating applied. Thus, while microorganisms occur on the surface of the last film applied, the degree of microbiological growth that will occur is also influenced by the composition of the undercoats. All the above factors should be considered in the selection of a coating resistant to discoloration by microorganisms.
4. Significance and Use
4.1 The growth of fungi and algae in and on the surface of paint films represents a major cause of discoloration or disfigurement of painted surfaces. This practice covers the preparation of coatings for testing, their application on substrates, and the arrangement of the coated panels on exterior test fences to determine the degree of microbiolog ical attack that may occur on the surface of the coatings over a period of time. This practice is intended to provide guidelines for, and a discussion of, the various factors critical in selection of exterior coatings resistant to discoloration ( 9 disfigurement by algae and fungi.
5. Preparation and Application of Coatings
5.1 Conditioning of Coatings Prior to Application--Indi vidual coatings to be used in the paint system should be properly aged under suitable conditions prior to testing. Hydrolysis, amalgamation, absorption, and other physical and chemical changes that may have a profound influence on the resistance of a coating to microorganisms usually increase with increasing temperature. It is recognized that actual storage periods of paints prior to use may vary from one to several years, and the peak temperature encountered may be as warm as 160F (70C). However, a recommended conditioning period consists of 1 year at room temperatures or 1 month at 125F (50C) as in Test Method D 1849. The conditioning of coatings prior to testing shall be agreeable to the producer and the user in the case of a referee test
5.2 Preparation of Coatings for Application--Prior to application ofthe various coatings to be included in the total paint system, thoroughly reconstitute each coating by appro priate mixing or shaking. At the time of application, there must be no settling, incompatibility, or other stability problem observable in the coating in the container.
5.3 Application of Paint System--Apply each coating ffi the total paint system in an appropriate manner to provide a specified and reasonably uniform film thickness. The pres ence and thickness of different coatings, in the complete system can have a pronounced effect on the degree of microbiological discoloration that will occur. Thus, each

03int in the system must be applied as recommended by the Manufacturer. It is important that the procedure and the user
gree on the type of coatings and the spreading rate of each gating in the final test film. The drying time between coats ,,,id the curing time of the total system prior to exposure should also be specified. Recommended practice for house paint is 2 days between coats and no less than 7 days and not j0nger than 1 month prior to the exterior exposure. Induspial and industrial maintenance coatings may require a different practice that should be acceptable to the producer jijd the user.
5.4. On each substrate use a test area not less than 48 in.2 (310 cm2) in size. When only one type of substrate is being uSed, expose at least duplicate panels. When more than one substrate is employed for each exposure condition, duplicate panels of each substrate are not usually required. In case of a isferee test, it is recommended that replication and size of test area be agreed on between the producer and the user. Common practice in the industry is to use 6 in. (nominal) by 36-in. (152 by 915-mm) panels for house paint exposures and to use 12-in. (305-mm) metal panels of various widths for exposures of industrial and industrial maintenance coat ings.
6. Substrates for Testing
6.1 General Considerations--The substrate on which a paint system is exposed can have a significant effect on the degree of microbiological discoloration that may occur. Coated wood surfaces generally support more mold and algae than do coatings on metals or masonry surfaces. This is perhaps due to some nutrients and greater porosity for retention of available moisture in wood surfaces. The type of metal substrate can have either an adverse or beneficial influence on the growth of fungi and algae. Some metals can inactivate certain microbiocides, thereby allowing greater microbiological discoloration. It should also be recognized that metals may also reduce the growth of microorganisms because oftoxic compounds resulting from weathering ofthe metal. Masonry surfaces generally inhibit microbiological growth because of their alkaline nature. However, this same characteristic can contribute to microbiological discoloration by hydrolyzing alkali-sensitive microbiocides that may have been used in the coating. The recommended substrates for testing coatings for resistance to discoloration by microor ganisms vary according to the intended use of the coatings. In referee cases, the substrate for testing shall be mutually agreeable to the producer and the user. Industrial coatings should be evaluated on the surface for which they are designed. Trade sales and industrial maintenance coatings are general-purpose coatings and should perform on a variety of substrates. For such coatings, test exposures on the following substrates are recommended for the indicated reasons.
6.2 Wood Substrates--Sapwood of pine and fir generally is considered conducive to growth of microorganisms. This may be due to nutrients in the wood and to the low dimensional stability, resulting in microcracking of coatings applied on the wood with subsequent mold growth in these cracks. Plywood, hardboard, and other wood-derived prod ucts support varying degrees of fungal growth depending on the nutrient value, degree of moisture absorption, and
dimensional stability of the base material. Redwood tends to have better dimensional stability and otherwise has insignif icant effect on the microbiological growth on coatings applied over it. Cedar lumber generally contains compounds that aid in resisting microbiological growth. Both cedar and redwood contain colored extractives that can bleed through coatings to discolor the surface. Some ofthese extractives can also be nutrients that contribute to microbiological growth, resulting in added discoloration.
6.3 Metal Substrates--Iron, galvanized steel, and alu minum are common substrates for paints. Iron and compounds generally inhibit microbiological growth. On the other hand, these metals may react with certain microbiocides to reduce the microbiological inhibition. Cer tain microbiocides can also cause discolored corrosion prod ucts or loss of adhesion by the coating on these surfaces. Aluminum is rather chemically inert and does not itself promote microbiological growth. It may, however, cause loss of microbiological resistance of coatings containing certain mercury compounds because of the amalgamation reaction by aluminum and mercury. This can result in loss of adhesion.
6.4 Masonry Substrates--The extremes of masonry sur faces generally consist of two conditions: fresh surfaces, which are relatively alkaline and free of fungi and algae, and weathered surfaces that are less alkaline and may be discol ored because ofmicrobiological growth. Weathered masonry surfaces represent useful test surfaces since microbiological contamination can grow through inadequately preserved coatings from the underside. Weathered masonry surfaces also offer a relatively uniform surface from panel to panel. Such uniformity is useful in statistically determining the relative effectiveness of various coatings or of various wash solutions for cleaning or "sterilizing" a surface before re painting. Exposures of coatings on both clean masonry panels and weathered panels can provide useful results and both are recommended as test substrates.
6.5 Moldy "Mildewed" Repaint Surfaces--Weathered paint films that are discolored by microbiological growth are also useful in determining the efficacy of wash solutions to clean or "sterilize" an old paint film prior to repainting. Such moldy repaint surfaces also are useful in determining the resistance of a coating system to discoloration due to microorganisms growing through the paint system from the underside.
7. Arrangement of Coated Panels on Exterior Test Fences
7.1 Paint systems should offer long-term resistance to microbiological growth both in completely exposed areas and in shady, protected areas. Where sunlight and moisture are in abundance, chalking will occur. However, chalking is slow to occur in shady areas. Thus, an effective microbiocide for a coating must have long-term light stability, heat resistance, and be sufficiently soluble and toxic to cause microbiological inhibition, and it must have limited solu bility or teachability from the coating system such that it remains in the system for sufficiently long periods of time. Ideally, it should not induce chalking for cleaning of the surface, since such chalking will cause fading or tinted paints.
7.2 The most realistic conditions of exposure can best be realized on the exterior of houses. Unfortunately, buildings
517

# D 3456
with the various substrates and located in desirable localities and geographic locations are seldom available. However, comparisons of various coating systems can be made by exposing coated panels on exterior test fences. Positions of exposure should vary to include completely exposed weath ering conditions and also protection from weathering. The exposed conditions are useful in determining the influence of temperature, sunlight, moisture, various substrates, and subsequent chalking on a coating. The protected, shady exposures are useful in determining the relative microbiolog ical inhibition of coatings in the absence of chalking.
7.3 Construction of test fences for protected or shady conditions can be similar to that given in Practice D 1006 but modified to provide for a larger test area in the protection of an eave. A protected area under an eave facing north best represents the desired conditions. This eave should have a minimum of 18 in. (455 mm) overhang. The panels should be exposed in a lapped position as would be encountered with wood siding on a house. The test area for each system should begin immediately under the eave and continue down the test fence to a point at least 2 ft (610 mm) below an imaginary horizontal line, which is derived by projecting at a 45 angle from the outer edge of the eave, downward and inward to the test panels. Thus, an 18-in. eave would require a minimum of 3.5 ft (1.06 m) of test panels, beginning immediately under the eave down to the bottom edge of the exposure area. The inverted horizontal surface of the soffit under the northerly eave is an ideal test environment as well. Also, this area does not usually collect excessive dirt. Thus, any microbiological discoloration is readily apparent.
7.4 Construction of test fences for exposed conditions can be similar to that in Practice D 1006 but modified to provide for offset panels held at an angle of 5(5) off vertical facing south. Construction should allow exposures such that mois ture falling on the test area of one panel will not drip on the next panels below.
8. Geographic Location of Test Fences
8.1 The climatic and environmental conditions of the test fences should be similar to those of the areas in which the
paint system is intended for use. For coatings to be used nationally, it is desirable to expose in warm and humid environments. Exposures should be made in both shady conditions and in direct sunlight. It should be recognized that the microflora occurring in different parts of a country will vary so that mold and algae encountered in one test location may not necessarily be those of another.
9. Periods of Exposure
9.1 The time of the year when the initial exposure is first made can be critical. Because of differences in weather from year to year, results of exposures from one year to another may also vary. In order to compare the tendency for two or more paint systems to become discolored through microbio logical growth, it is advisable that the paint systems be exposed at the same time. It is frequently desirable to include both a positive and a negative control. The negative (fail) control is a paint system known to discolor quite severely under standard exposure conditions and may be used on each panel. A positive (pass) control is a paint system that will perform reasonably well in the same known exposure conditions.
10. Ratings for Microbiological Discoloration
10.1 Ratings should be made in accordance with Test Method D 3274.
10.2 It is desirable to obtain mold ratings prior to initia tion of chalking and erosion, since it is prior to this occurrence that a paint film is most prone to discoloration by spore-cluster type (dirt-like) mold growth. Chalking can occur within several months, or it may never occur, de pending on the paint formulation and its exposure to weathering conditions. Therefore, mold ratings are suggested after 3, 6, 9, 12, 18, and 24 months and yearly thereafter. Make yearly inspections immediately following seasonal growing conditions. Most extensive microbiological growth usually develops during periods of warm and humid weather. Thus, make any ratings of microbiological discoloration immediately following the warm, humid period of the year.

results obtained from humid/dry cycling and the results expected in a specific period of time in service because of variations resulting from geographic locations, location within the building, care of the panel (such as waxing), and variations within materials involved.
4. Test Panels and Panel Preparation
4.1 Test panels shall be regular production finished panels if available.
4.2 If regular production finished panels are not available the purchaser and the seller shall agree upon the following variables: type of wood or wood substrate, sanding method(s) and paper(s), sealer(s) or toner(s), fillers), stain, primer or basecoat, print(s), and topcoat(s), methods of application, and the number of surfaces to be coated. If rotary-cut veneered panels are used, it should also be agreed whether the veneer is to be open or close faced.
5. Apparatus
5.1 Oven--a gravity-convection or forced-ventilation electrically heated oven meeting the requirements of Specifi cation E 145 and providing a continuous temperature of 122 3.5F (50 2C).
5.2 Constant Elevated-Temperature and ConstantHumidity Chamber, maintained at a relative humidity of 97 2% and a temperature of 122 3.5F (50 2C).
5.3 Constant-Temperature and Constant-Humidity Cham ber, maintained at a relative humidity of 50 5 % and a temperature of 73.5 3.5F (23 2C).
6. Test Specimens
6.1 Test specimens shall be large enough to be representa tive of the material or product and to permit easy observa tion of possible defects. This usually means a minimum area of approximately 12 by 12 in. (300 by 300 mm).
6.2 Unexposed control specimens of each coating or coating system or product tested shall be held in reserve in a constant-temperature and constant-humidity area (5.3) to prevent any changes.
6.3 Whenever possible, comparative control specimens of a similar material or product with known service character istics should also be exposed.
6.4 Three specimens are usually adequate unless a lack of uniformity is suspected in the substrate, coating, or coating system.
7. Conditioning
7.1 Place the specimens in a conditioned room or chamber (5.3) so that air is free to circulate on all sides of
DUPO 502 97700
D 3459
each specimen so as to avoid localized overheating. Allow them to remain there 14 days.
8. Procedure 8.1 Measure the dry film thickness of the coating system
on the control panel to the nearest 0.1 mil (2.5 pm) by an appropriate method such as Test Methods D 1005, Methods D2691, or an Optical Surfacer Analyzer.4 The results of humid dry cycling are directly affected by the dry film thickness as well as by the coating system itself.
8.2 After conditioning measure thickness of each spec imen to the nearest mil (25 pm) at a marked location about 1 in. (25 mm) from one edge and midway along one side at the beginning and after each change of conditions.
8.3 Place the specimens in the oven maintained at 120 3.5F (50 2C) (5.1) so that air is free to circulate on'all sides of each specimen to prevent localized overheating. After 48 h remove the specimens from the oven and place them in the high-humidity elevated-temperature chamber (5.2) so that air is free to circulate on all sides of each specimen. Leave the specimens in the humidity cabinet 48 h. The period of 48 h of dry heat followed by 48 h of humid heat constitutes one cycle. Expose the specimens to the number of cycles as agreed upon between the purchaser and the seller.
8.4 At each change of conditions during cycling, visually inspect each specimen under a strong light and at various
4 Gardner, H. A. and Sward G. G., Paint Testing Manual, 13th edition, ASTM STP 500, ASTM, 1972,
angles to the light for possible damage or change. Note any change in or damage to each specimen. Damage may be found in the base material (plywood, hardboard, flakeboard solid wood, etc.) or in the coating, in a finish or overlay on the substrate material. Some defects that may occur as a result of humid/dry cycling are as follows: checks, cracks, splits, blisters, (see Test Method D 714) raised grain, local ized lumps or swelling, photographing of substrate through the coating, loss of particle adhesion, loss of adhesion in glue lines, change in the dimensions of the overlay, changes in surface color, gloss, or hardness, cohesion loss in the coating. If open-faced rotary-cut veneer has been used, checking may result from this fact.
9. Report
9.1 Report the following information: 9.1.1 Complete description of the test material and the comparative control material, 9.1.2 Size and number of the specimens, 9.1.3 Dry film thickness of the material under test and the control (comparison material). 9.1.4 Number of cycles agreed upon between the pur chaser and the seller, 9.1.5 Any deviations from the standard procedure, and 9.1.6 Defects or changes as described under 8.4.
10. Precision
10.1 Since the observed changes can take several forms no numerical values have been developed, and meaningful estimates of precision cannot be given. Round-robin tests showed that cooperators can obtain satisfactory agreement in ranking of results.
The American Society for Testing and Materials takes noposition respecting the validity of any patent rights asserted In connection with any Item mentioned In this standard.

4. Significance and Use
4.1 The rate of evaporation of volatile liquids from a solution or dispersion is important because it affects the rate of deposition of a film and flow during deposition, and thereby controls the structure and appearance of the film. In the formulation of paints and related products, solvents are chosen based on the evaporation characteristics appropriate to the application technique and the curing temperature.

8. Procedure
8.1 Record the position of the filter paper as indicated by
alignment of the sighting disk with its mirror image. This is
the no-load position.
8.2 Raise the wire mesh bracket until the bottom of the
disk support rests lightly on it.
8.3 Withdraw into the syringe 0.70 mL of the solvent
which is at 77 1.0'F (25 0.5C). Make certain that all air
bubbles are expelled from the syringe and the needle before
application of the specimen to the filter paper.
8.4 Insert the hypodermic needle into the small opening
on the right-hand side of the instrument and position the
needle tip so that it almost touches the disk and is just oven
the line that was drawn.
Ml
8.5 Start applying the solvent to the disk. As the first drop p
hits the disk, start the timer. The solvent should be applied at
a uniform rate in 2 s and as evenly as possible along the
drawn line. To ensure consistent specimen size, touch the tip 1
of the hypodermic needle to the filter paper to dispense the 4
last drop of solvent
8.6 Immediately lower the wire mesh bracket away fromA
t]the disk support. Obtain the first reading of the position of
the sighting disk at 40 s and then every 20 s. Record the time
and the scale reading on the report form. A sample report
form is shown in Annex A2.

(Taken as equivalent to specific gravity but with units
of g/mL) g = scale reading taken during evaporation of aliquot, Z = zero percent evaporated, scale reading = N - (S/Q.
and R -- no-load scale reading (100 % evaporated reading).
9.2 Plot the percent evaporated against elapsed time in
seconds and draw a smooth curve through the points. From the curve, determine at 10 weight % increments to 90 % and for 95 and 100 % evaporation the time in seconds to the nearest value as follows:

N' 6--The curve drawn through the various points should pass
through zero or the origin. If it passes to the right of the origin, the delivery time was in excess of 12 s or an aliquot larger than that specified was delivered. If it passes to the left of the origin, then the aliquot was
smaller than specified.
10. Report
10.1 Report the elapsed time in seconds at 10 weight % intervals through 90 % and for 95 and 100 % evaporation, and the relative evaporation rate (-butyl acetate = 1.0). Relative evaporation rate is calculated from the 90 weight % evaporated times for the test solvent and for n-butyl acetate (99 % ester).
11. Precision8
11.1 On the basis of an interlaboratory study of the test method in which operators in six laboratories determined the 90 % evaporation point of six solvents covering a broad range in evaporation rate, the between-laboratories coeffi cient of variation was found to be 6.3 % relative at 24 degrees

of freedom after discarding two divergent values. On the basis of the results obtained by three laboratories on three of the solvents having 90 % evaporated times of 200 to 600 s, the within-laboratory coefficient of variation was found to be 0.83 % relative at 18 degrees of freedom. Based on these coefficients, the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
11.1.1 Repeatability--For solvents with 90 % evaporation times of 200 to 600 s, two results, each the mean of two determinations, obtained by the same operator on different days should be considered suspect if they differ by more than 2.5 %.
11.1.2 Reproducibility--Two results, each the mean of two determinations, obtained by operators in different labo ratories should be considered suspect if they differ by more than 18.2 %.
METHOD B--EVAPORATION RATE USING THIN-FILM EVAPOROMETER, AUTOMATIC RECORDING
12. Apparatus
12.1 Evaporometer, Automatic Thin-Film Evaporometer,9 as shown in Fig. 3.
12.2 Filter Paper Disk--See 5.4. 12.3 Syringe--See 5.5. 12.4 Dehumidification Equipment--See 5.6. 12.5 Strip Chart Recorder--Any strip chart recorder ca pable of recording the output signal (0 to 15 mA) from the electronic optical weight-sensing device. The recorder should provide a range ofchart speeds including lA to 2 in. (6.3 to 50 mm)/min. It is also desirable for the recorder to accommo date 2 or more mA ranges in order to regulate the sensitivity of measurement.
13. Preparation of Evaporometer
13.1 Place the filter paper disk on the wire frame threading the hook through a small hole in the center of the paper. Attach the wire frame to the support hook in the evaporometer.
13.2 Close the evaporometer and cabinet doors and equil ibrate both chambers as in 6.2.
13.3 Adjust the air flow to 21 L/min.
14. Conditioning of Sample
14.1 See 7.1.
15. Procedure
15.1 When all components (including the filter paper in place) are at equilibrium, adjust the recording pen to a prominent "zero" position near the edge of the chart on the recorder; then turn the switch for the chart motor to the OFF position. This constitutes the "zero" load and time position for the test.
' The automatic Shell thin-film evaporometer. Apparatus Catalog No. FI522 is available from the FLC Instruments, Inc., 2055 Comprehensive Drive, Aurora, IL 60505. Another evaporometer, the Arizona Instrument EV-l, is available (Arizona Instrument Coip., 2078 East University Drive, Tempe, AZ 85281-4098). Precision data is not yet available, but the instrument operates in the same manner as that described in this test method and is reported to give similar results.

evaporation curve. The 0 % evaporated or full-load point' ajj| zero time can be obtained either by extrapolation of the! evaporation curve back to zero evaporation time or calcula-i tion using the weight of the sample and the calibration data
15.4 When all is ready turn the strip chart motor switch to the ON position and simultaneously start distribution of the specimen onto the filter paper. The complete specimen should be dispensed uniformly in 10 2 s along the line. The recorder pen will "advance" immediately to an "apex" position equivalent to the total weight of the specimen, less that portion that evaporated dining the application period. The pen will gradually return to its original position as the solvent evaporates and the chart advances. The evaporation is complete when the recording pen has returned to its original "no-load" position.
N' 9--It is common for the final portion of the curve to exhibit a
"tailing-off." This is due to artifacts of the method such as (1) hydrogen bonding of the last traces of solvent with the cellulose fibers of the filter paper and (2) a gradual diminution of the area of the filter paper wet by solvent (that is, in the final stage of evaporation, drying of the paper progresses from the outer edge toward the center of the disk). Thus, it is common practice for the evaporation cycle to be considered "complete"
for the instrument (See Annex A3). The routine calculation*) of the 0 % evaporated, full-load point is recommended as a check for correct specimen size.
16.1.2 Multiply the distance along the time axis from the zero starting time by the chart speed factor in seconds giving the total elapsed time for each defined point along the curve. For example, at a chart speed of 1 in./min and a 20 % evaporation point at 3.30 in. the evaporation time is 198 s (60 X 3.30 = 198). Use the procedure given in 9.2 to round results.
16.2 An alternative method of reporting evaporation results is to express an Area Evaporation Rate, in terms of grams evaporated per second per square centimetre of evaporating surface. ,11115 method is not exact .because the evaporation rate is not linear throughout the complete evaporation period, but it is a useful approximation to represent the general volatility of a solvent. The calculation of evaporation rate is as follows:

Area Evaporation Rate, R = --C--x D-- X 108
^iiere: g = evaporation rate, g/cm2s x 108, q *= a factor = 0.00438 mL/cm2 obtained from:

% increment are disregarded), = total evaporating surface of 90-mm di
ameter filter paper,
then C = ' 71280'8" = 0.00438 mL/cm2
C = specific gravity of the solvent at 77F (25Q, i = 90 % evaporation time, s, and
g = 10 % evaporation time, s. The multiplicand, 10s, is inserted in the equation to avoid decimal fractions.
17. Precision8 17.1On the basis of an interlaboratory study of the test
method in which operators in four laboratories determined the 90 % evaporation point of seven solvents covering a broad range in evaporation rate, the within-Iaboratory coef ficient of variation was found to be 1.78 % relative at 35 degrees of freedom and the between-laboratories coefficient of variation was found to be 3.88 % relative at 28 degrees of freedom. Based on these coefficients, the following criteria should be used forjudging the acceptability of results at the 95 % confidence level:
17.1.1 Repeatability--Two results, each the mean of two determinations, obtained by the same operator on different days should be considered suspect if they differ by more than 5.1 %.
17.1.2 Reproducibility--Two results, each the mean of two determinations, obtained by operators in different labo ratories should be considered suspect if they differ by more than 11.25%.

Al.l Remove the filter from its wire support and replace it with a small piece of aluminum foil, about 50 by 50 mm; then again suspend the support from the coil spring. Record the position ofthe sighting disk. Load the spring by placing a 1-g analytical balance weight onto the aluminum foil and again record the elongation of the spring. Thus, the spring constant, C, in grams per centimetre, is equal to 1.000 g divided by the elongation in centimetres.
A 1.2 Standardization of the Evaporometer--Since there may be slight variations in manufacture, the evaporometer should be standardized prior to routine usage. The standard solvent, rt-butyl acetate, (99 % ester), should have a 90 % evaporation time of 470 10 s under the prescribed test conditions. If the evaporation time is outside these limits, a slight increase or decrease of the air flow should be sufficient to bring about the desired results.

A3. CALIBRATION OF THE THIN-FILM EVAPOROMETER, AUTOMATIC RECORDING
A3.1 The total deflection of the recording pen in chart units divided by the weight added corresponds to the sensitivity of the apparatus. For example, if the total pen deflection is 60 chart divisions for a 0.500-g weight, the sensitivity factor is 120 chart divisions per gram. This value can then be used to establish the 100 % specimen load at "zero" evaporation time and to calculate the percent evapo rated at various time intervals. For instance, pure n-butyl acetate (99 mol %) has a density of 0.878 at 250C, so a 070-mL specimen at the cited calibration would deflect the pen 73.75 chart units (that is, 0.878 X 6.70 X 120 = 73.75).
Each 10 % increment that evaporates corresponds to 73.75
chart divisions.

1. Scope 1.1 This test method is intended as a screening test to
determine if the solids in a paint contain more than 0.5 % lead. The test described barely detects the presence of 0.4 % but gives a definite positive result at the 0.5 % level.
N' 1 --This test method may be used to detect the presence of lead
at concentrations higher or lower than 0.5 % by making appropriate changes in the specimen size and reagent quantities specified.
1.2 Paints giving an unexpected positive or questionable result should be analyzed quantitatively for lead, using Test Method D 3335.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility ofthe user of this standard to establish appro priate safety and health practices and determine the applica bility of regulatory limitations prior to use. Specific hazard statements are given in Section 7.

3. Summary of Test Method
3.1 The sample of liquid paint or dried film is prepared by dry ashing a weighed specimen at 475 to 500C. The ash is extracted with hot sodium hydroxide solution and a drop of the extract is transferred to filter paper. Lead present is oxidized to lead peroxide with bromine water, then treated with "tetrabase" to produce a blue quinoidal salt. Known amounts of lead are added to standard paints that are concurrently tested to provide a base for comparison.

solution into a 50-mL volumetric flask and dilute to volume with water.
6.9 Toluene, technical grade. 6.10 Lead Standard Stock Solution, Solvent-Based (1 mg/mL)--Dissolve 4.2 g of lead naphthenate (containing 24 % lead) in LOO mL of toluene and dilute to 1 L.
N' 2--Other toluene-soluble lead driers such as lead tallate, lead
linoleate, and lead octoate may also be used provided that the lead content is accurately known and the appropriate weight is diluted to 100 mL to provide a toluene solution containing l mg/mL of lead.
6.11 Lead Standard Working Solution, Solvent-Based (0.2 mg/mL)--Pipet 10 mL of the solvent-based standard stock solution into a 50-mL volumetric flask and dilute to volume with toluene.
6.12 Sodium Hydroxide Solution (12 % w/v)--Carefully dissolve 12 g of sodium hydroxide in 100 mL <5f water.
6.13 Paint, Standard Solvent-Reducible, any solvent-re ducible paint known to contain less than 100 ppm of lead.
6.14 Paint, Standard Water-Reducible, any waterreducible paint known to contain less than 100 ppm of lead.
6.15 Tetrabase Reagent (4,4'-Methylenebis (N,N-dimethylaniline)), l % in 10 % Acetic Acid--Dissolve 1 g of tetrabase5 in 50 mL of water to which 10 mL of glacial acetic acid has been added. Dilute to 100 mL with water.
7. Hazards 7.1 Glacial acetic and concentrated nitric acids will cause
burns of the skin and eyes. Sodium hydroxide is corrosive. Use care in handling these materials. Avoid contact with skin. Refer to suppliers' Material Safety Data Sheets. Bro mine water should be prepared and used in a laboratory hood.6
7.2 Use only a rubber bulb aspirator for pipetting liquids.
8. Procedure 8.1 If the sample is a liquid coating, mix it until homoge
neous, preferably on a mechanical shaker. Determine the nonvolatile content in accordance with Guide D 2832.
N' 3--Recover dried paint films from previously coated sub
strates (being careful not to remove any underlying material from the substrate) or prepare in the laboratory from liquid samples. For the laboratory preparation, flow some ofthe well-mixed sample onto a clean glass plate. The use of a paint draw-down bar is recommended to obtain a uniform dim thickness not exceeding 2 mils (50 pm). Allow to dry in an oven at 105C for a minimum of 1 h. Scrape the dried film off the glass plate, preferably with a single edge razor blade.
8.2 Weigh to 0.1 mg, 50 mg of paint solids into a porcelain crucible or 50-mL glass beaker. For a liquid coating, determine the specimen weight to be taken by the following equation:
where:
S' = specimen weight, g, and C = nonvolatile content, %

* Saturated bromine water may be purchased from chemical supply houses.
N' 4--Crucibles or beakers used in this test method should k,
new or in very good condition. Otherwise, it is possible that some ]Lj
may be lost and a false negative obtained.

8.3 Weigh 50 mg of solids from the appropriate standard paint (solvent-reducible or water-reducible) into each of tw0 additional porcelain crucibles or 50-mL glass beakers. Usk a 2-mL glass syringe, add 1.0 mL of the appropriate 200-pp^j standard working solution (solvent-reducible or water-re. ducible) to one of the crucibles or beakers, and 1.8 mL to thP other.
N' 5--The standard paint to which has been added 1.0 ml 0f
standard working solution contains approximately 0.4 % lead based 0n the paint solids, and the one to which has been added 1.8 mL of standard working solution will contain approximately 0.72 % lead based on the paint solids.

8.4 Place all three crucibles or beakers on a cold hot plate and slowly increase the temperature until the material jj dried. With some types of coatings, an initial oven-drying at 105C may be necessary to remove solvents without incurring losses due to spattering.
8.5 When the specimens appear to be dry, or when starting with a dried film, gradually increase the temperaturt of the hot plate until the material chars.
8.6 After charring is complete, place the crucibles or beakers in a preheated muffle furnace and ash at 475 to 500'C.
8.7 When the ashing appears to be complete, (approximately 1 to 2 h) remove the crucibles or beakers from the muffle furnace and allow them to cool to room temperature. Add 5 mL of 3 N sodium hydroxide solution to each crucible or beaker and mix thoroughly with a stirring rod. Scrape any adhering residue from the sides or bottom of the container and break up any particles, using a separate stirring rod for each specimen.
8.8 Place covers on the crucibles or watch glasses on the beakers, and boil gently for approximately 5 min. Remove from the hot plate and allow the contents to settle. Do not fdter.
8.9 With the tip ofthe stirring rod, transfer 1 to 2 drops of each extract to the center of a piece of filter paper. Using separate droppers, successively apply directly on each spec imen spot a drop of bromine water and a drop of NH4OH solution. Remove excess ammonia by holding each filter paper over a hot plate until no odor is detectable, but do no! take to complete dryness. Place 2 drops of tetrabase reagenti on each spot and compare the color developed on the specimen spot with those on the standard paint spots. To f ensure that maximum color development has been achieved, add I or 2 more drops of tetrabase reagent on the center of each spot after the first addition has almost-dried (if still wet the color may diffuse).
N' 6--Although the color is stable, it is barely visible in the rangf i

6.3 Test Coating System--The test antifouling coating may be applied to the standard primer system, or to any other suitable anticorrosive primer system.
7. Safety Precautions
7.1 Caution--Antifouling paints contain toxic materials that could cause skin and eye irritation on contact and adverse physiological effects if ingested or inhaled. In the preparation of panels and the application of various types of antifouling paints the use of appropriate protective clothing and equipment is required consistent with local, state, and federal government regulations, and recognized industrial and technical standards. Spills, overspray, and unused mate rial should not be flushed down the drain, but should be disposed of as hazardous waste.
8. Procedure
8.1 Abrasive blast the required number of panels to near-white metal (Sa 21/2 of Method D2200) to obtain a profile of 1 to 1.5 mils (25 to 38 pm).
N' 1--A profile of 1 to 1.5 mils (25 to 38 pm) can be obtained
with the following parameters: (1) Type and size of grit. No. 46 (sand); (2) Pressure, 90 psi (620 kPa); (3) Angle, 90 deg; (4) Distance from surface, 3 to 5 in. (75 to 125 mm); (5) Nozzle size, % in. (9 mm).
8.2 On the clean, dry, uncontaminated, blasted surface apply to each standard panel one coat of pretreatment coating MIL-P-15328D to give a nominal dry film thickness of V2 mil (13 pm).
N' 2--All coating drying times are for a minimum temperature of
2lC and a maximum relative humidity of 70 %..
8.3 Within 24 h of application ofthe pretreatment coating apply the first coat of red lead vinyl primer MIL-P-15929C. Apply a total of four coats of red lead vinyl primer to give a nominal dry film thickness of 6 mils (150 pm). Allow a minimum of 2 h and a maximum of 24 h drying between coats of red lead vinyl primer.
8.4 Allowing a minimum of 2 h and a maximum of 24 h drying after the last coat of red lead vinyl primer, apply the first coat of vinyl antifouling coating MIL-P-15931B to the
5 See also U.S. Military Specification MIL-S-22698, Type 1, Class A.
standard panels, and the test coating to the test panels. A 3/4-in. (19-mm) numbered vinyl tape can be applied before the second coat of antifouling coating for identification. Allowing a minimum of 2 h and a maximum of 24 h drying after the first coat, apply a second coat of the respective antifouling coating to give a nominal dry film thickness for both antifouling coats of 4 mils (100 pm).
8.5 Before immersion permit the second coat of antifouling coating to dry a minimum of 4 h and a maximum of 2 weeks, the latter time allowing for shipping the panels to the immersion site.
8.6 Expose for a minimum period of 1 year at an immersion site with a high incidence of fouling as indicated by attachments on a dark nontoxic surface such as slate. A monthly fouling census as well as a yearly accumulation when appropriate is required.
8.7 Evaluate the antifouling panels for surface fouling and physical condition of the film system at least monthly as follows using the report form in Table 1.
8.7.1 Fouling on Surfaces--Rate fouling present on that portion of the antifouling test surface which is intact at the time of inspection (see 9.1). Rate both sides of the panel if appropriate. Ignore fouling present on the substrate or on anticorrosive undercoats. Barnacles, polychaetes, coelenterates, etc., that are immature or loosely attached should be so reported in the appropriate space. Report fouling by initial algal germination, low-form algae and diatoms as "algal slime." Report absorbed organic and inorganic chemicals,
trapped silt and detritus, and other unidentified slimes as "silt."
8.7.2 Physical Condition--Rate the condition of coating films in accordance with 9.2. Record qualitative descriptions of film deterioration and discoloration in this column, and unless otherwise specified, refer only to the antifouling test surface. Indicate deterioration of undercoats, when evident, by the notation "A.C.". For example, "Peeling, A.F. from A.C." or "Chipping, A.C. from steel".
9. Calculations:
9.1 Fouling Resistance (F.R.)--Award each test surface free of fouling except for the presence of algal spores and other biological slimes a rating of 100. Reduce the rating to 95 if only incipient fouling is present. If mature forms of fouling are present, obtain the rating by subtracting from 95 the sum of the number of individuals present and percent surface covered by colonial forms. For example, if the "fouling on surface" is:
Bam
E.B. Others
6, 3 to 10 mm None Mol 1,20 mm Al-g (green) 10 %
then the F.R. percent rating would be 95 - (6 + 1 + 10) = 78.
9.2 Physical Condition: 9.2.1 Antifouling Film (A.F.)--Award an antifouling test surface having no physical defects a rating of 100. Subtract
the percent surface affected by film defects from 100 to obtain the rating for imperfect films.
9.2.2 Anticorrosive Film (A.C.)--Obtain the rating by the same procedure as 9.2.1.

Standard Test Method for Low Concentrations of Mercury in Paint by Atomic Absorption Spectroscopy1
This standard is issued under the fixed designation D 3624; the number immediately following the designation indicates the year of original adoption or, in the case of revision, die year oflast revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<) indicates an editorial change since the last revision or reapproval.
ei N' --Keywords were added editorially in July 1991.
1. Scope
1.1 This test method covers the determination of the content of mercury in the range between 10 and 1000 ppm (mg/kg) present in liquid coatings, coatings vehicles, or in dried films obtained from previously coated substrates. There is no reason to believe that higher levels could not be determined by this test method, provided that appropriate dilutions and adjustments in specimen size and reagent quantities are made.
1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility ofthe user ofthis standard to establish appro priate safety and health practices and determine the applica bility of regulatory limitations prior to use. Specific hazard statements are given in Section 7 and 9.1.1.
2. Referenced Document
2.1 ASTM Standard: D1193 Specification for Reagent Water2
3. Summary of Test Method
3.1 The sample of liquid coating or dried film is weighed into a polytetrafluoroethylene (PTFE)-lined acid decomposi tion vessel and digested at an elevated temperature using sulfuric and nitric acids. Use of a sealed acid decomposition vessel prevents loss of mercury during the digestion. The digested sample is diluted to a known volume with water and the concentration of mercury is determined using a coldvapor, atomic absorption technique.
4. Significance and Use
4.1' The permissible level of heavy metals in certain coatings is specified by governmental regulatory agencies. This test method provides a fully documented procedure for determining low concentrations of mercury present in both water and solvent-reducible coatings to determine compli ance.
5. Apparatus
5.1 Atomic Absorption Spectrophotometer--Any commer-
, 1 This test method is under the jurisdiction ofASTM Committee D-l on Paint : and Related Coatings and Materials and is the direct responsibility of Subcomjj mittee DO 1.21 oa Chemical Analysis of Paints and Paint Materials.
Current edition approved July 17 and Nov. 29. 1985. Published January 1986. Originally published as D 3624 - 77. Last previous edition D 3624 - 84. : 2 Annual Book ofASTM Standards* Vols 06.03 and 11.01.
cial instrument having an open sample presentation area in which to mount the absorption cell or an instrument designed specifically for the measurement of mercury using the cold vapor technique.
5.2 Recorder, 0 to 10 mV. 5.3 Mercury Source Lamp. 5.4 Absorption Cell--Standard spectrophotometer cells 100 mm long, having quartz end windows may be used. Prior to use, the cell must be positioned in the optical path of the spectrophotometer and held in place by suitable clamps or straps. The cell should be carefully aligned both vertically and horizontally to give the maximum transmittance. 5.5 Reduction Vessel--Cylindrical gas washing bottle, 250-mL, equipped with a coarse (40 to 60-p.m) fritted glass inlet tube and a standard-taper glass stopper. Polyethylene or poly(vinyl chloride) tubing may be used for connecting the reduction vessel to the absorption cell. 5.6 Flowmeter, capable of measuring a gas flow of 1 L/min. 5.7 Drying Tube--Approximately 6 by 3A-m. (150 by 20-mm) glass tube filled with magnesium perchlorate. The tube should be filled each day that it is in use, and the Mg(C104)2 should be replaced whenever it becomes satu rated (carefully observe after each analysis).
N' 1--Use ofan indicator desiccant at the exit end of the tube will
make this observation easier.
5.8 Water Vapor Trap--A second 250-mL gas washing bottle (the same as used for the reduction vessel). If pre ferred, a 250-mL Erlenmeyer vacuum flask fitted with a one-hole stopper and 200 mm of 5-mm outside diameter glass tubing, may be substituted.
5.9 Mercury Trap--A. 250-mL Erlenmeyer vacuum flask containing 75 mL of 10 % sulfuric acid and 75 mL of 0.1 N potassium permanganate solution to absorb the mercury vapor after analysis.
5.10 Circulating Oven, maintained at 140 5C. 5.11 Acid Decomposition Vessel, with 25-mL PTFE diges tion cup.3 5.12 Volumetric Flasks, 100, 250, and 1000-mL. 5.13 Paint Shaker. 5.14 Paint Draw-Down Bar.
3 Acid decomposition vessel manufactured by the Parr Instrument Co., 211 Fifty-third St, Moline, IL 61265 (Catalog No. 4745) has been found satisfactory for this purpose.

until the pink color is discharged. 8.5 Add 10 mL of SnCl2 solution to the bottle containing
no added working mercury standard. Immediately insert the fritted glass inlet tube, making sure that the stopper provides a good seal. Adjust the nitrogen flow rate to a previously determined optimum setting (see Note 3) and take a reading. A blank value greater than 5 % of full scale indicates either reagent or apparatus contamination. When the recorder, meter, or other readout device reaches a maximum value, it should be immediately zeroed. Repeat this blank determina tion until a steady, repeatable zero value is obtained at the maximum response.
N' 3--Optimum nitrogen flow rate may be determined by ana
lyzing 1-ug quantities of mercury (10 mL of working mercury standard diluted to 100 mL) by this procedure, varyingthe flow rateto determine the optimum mercury signal and time required for analysis. Then use this optimum flow rate for all analyses, unless a change is made in the volume or geometry of the apparatus.
8.6 Similarly treat each standard solution made up in 8.4, recording the maximum peak height for each. When the recorder pen begins dropping, remove the fritted glass inlet tube from the gas washing bottle and insert it into another bottle containing only water. Continue nitrogen flow until the absorbance reaches zero, when the apparatus is ready for the next solution.
N !' 4--Because mercury vapor is very toxic, take precautions to
avoid its inhalation. Bubble the exhaust from the absorption cell through an absorbing solution consisting of equal volumes of 0.1 N KMn04 solution and 10 % H2S04 (see Fig. 1). Do not discharge the absorbing solution into a sewer system.
8.7 Construct a standard curve by plotting peak heights versus micrograms of mercury. Peak heights used should be the mean of duplicate determinations on each solution.
9. Procedure
9.1 If the sample is a liquid coating, mix it until homoge neous, preferably on a mechanical paint shaker. Prepare at least two replicate specimens by weighing to 0.1 mg by difference from a dropping bottle or syringe, 100 to 200 mg of the mixed paint into the PTFE insert of the acid decomposition vessel. Place the insert in an oven set at 60"C (140F) for 1 h to remove all volatiles.
9.1.1 Caution--If the solvent present in a sample is not removed prior to the digestion step as recommended, poten tially dangerous pressures may result when the vessel is heated at 140C.
9.2 If the sample consists of dried film, coarsely grind it and weigh 50 to 100 mg by difference from a weighing bottle into the digestion vessel.
N"#' 5--Recover dried paint films from previously coated sub
strates (being careful not to remove any underlying material from the substrate) or prepare in the laboratory from liquid samples. For the laboratory preparation, flow some ofthe well-mixed sample onto a clean glass plate. The use of a paint draw-down bar is recommended to obtain a uniform wet film thickness not exceeding 2 mils (50 pm). Allow the film to dry in an oven at 60C for a minimum of 1 h. Scrape the dried film off the glass plate, preferably with a single-edge razor blade.
9.3 Pipet 5 mL of concentrated H2S04 and 3 mL of concentrated HNOs into the decomposition vessel insert, using a fume hood for the operation. Seal the vessel tightly and place in the circulating oven at 140'C for 1V2 h. Remove
the vessel from the oven and allow it to cool slowly to room temperature.
NOTE 6--Do not assist cooling by putting the vessel in a refrigerator or freezer, or by submerging it in a cooling liquid; otherwise mercury losses may occur due to leakage of pressurized gases resulting from uneven contraction of the bomb parts and PTFE seal.
N"#' 7--Analysis of the digested specimen (9.4 to 9.7) should be
completed within 1 h after the digestion step.
9.4 When completely cooled, carefully unseal the vessel in a fume hood, add approximately 5 mL of cold water and swirl gently. Quantitatively transfer the contents to a 100-mL beaker, using several small quantities of water. Dilute to a volume of 30 to 40 mL and filter through filter paper directly into a 100-mL volumetric flask. Wash the residue on the filter paper several times with small volumes of water. Dilute to volume with water and mix thoroughly.
9.5 Transfer an aliquot of each digested specimen con taining not over 2 jxg of mercury to a 250-mL gas washing bottle. Add enough water to make a total volume of 100 mL. To each bottle, add 5 mL of concentrated H2S04 and 3 mL of concentrated HN03 and mix thoroughly.
N$%' 8--If large aliquots are taken for analysis, reduce the amount
of added H2S04 and HN03 proportionately to compensate for the amounts present in the digested solutions.
9.6 Proceed with the addition of KMn04, NH2OH>HCl, and SnCl2 solutions as described in 8.4 and 8.5. Record the maximum peak height for each solution.
9.7 If the response obtained is above or below the response obtained for the standards (8.7), repeat 9.5 and 9.6 using an appropriate aliquot size. Determine the concentra tion of mercury present in microgram per millilitre from the calibration curve.
10. Calculation
10.1 Calculate the mean concentration of mercury in the sample as follows:
mercury in sample, ppm (mg/kg) = (100 x C)/(F x 5)
where: C = concentration of mercury in aliquot used, pg/mL, F = dilution factor from 9.5 (aliquot volume used), and S -- grams of sample.
11. Report
11.1 Report the mercury content in the material being tested and whether the analysis was conducted on a liquid coating or a dried film.
12. Precision and Bias5
12.1 Precision--The precision estimates are based on an interlaboratory study in which seven different laboratories analyzed in duplicate, on two different days, four samples of water-reducible paints and four samples of solvent-reducible paints containing from 1 to 1000 ppm mercury. The within laboratory coefficient of variation was found to be 6.4 % relative at 42 degrees of freedom, and the between-laboratory coefficient of variation 10% relative at 36 degrees of freedom. Based on these coefficients, the following criteria

should be used for judging the acceptability of results at the
95 % confidence level: 12.1.1 Repeatability--Two results, each the mean of du
plicate determinations, obtained by the same operator on different days, should be considered suspect if they differ by more than 18 % relative.
12.1.2 Reproducibility--Two results, each the mean of duplicate determinations, obtained by operators in different
laboratories, should be considered suspect if they differ ( ,

j, pigment, Vehicle Separations (Centrifugal)
5.1 The methods listed in this section cover centrifugal separation of pigment from vehicle. The pigment may then be analyzed as described in subsequent sections. More recent methods utilizing analysis of the whole paint by atomic absorption spectroscopy may be preferred due to greater speed and accuracy.
5.2 Separation of the vehicle from the pigment is generally (be first step in coatings analysis. There are three ASTM methods covering the use of centrifuges:
5.2.1 Test Method D 2371 describes the use of the normal laboratory centrifuge that develops 2000 g. It should be used where a quantitative determination of the amount of pig ment in the coating is required.
5.2.2 Method D 2372 covers use of a high-speed centri fuge that develops 10 000 g and is used when analysis of the vehicle is of main interest.
5.2.3 Method D 2698 covers use of a centrifuge that develops at least 32 000 g. Determination of the pigment content is the main objective of the method although the separated pigment may be solvent-extracted to remove residual vehicle.
N,-' 5--Centrifuge methods do not generally give good separations
of pigments that bleed (partially dissolve) or have low densities and fine particle sizes (such as carbon black).
5.3 U.S. Federal Test Method Standard 141 contains two centrifuge methods. Federal Method 4021.1 is similar to Test Method D 2371 except that additional extraction mixtures are listed for difficult pigments and for cellulosic and vinyl lacquers. Federal Method 4032 is similar to Method D 2698 but has the same extraction solvents as in Federal Method 4021.1.
6. Solvent Separation
6.1 Practice D 3272 covers a vacuum distillation proce
dure that separates the solvents from the nonvolatile portion
of paints so they may be analyzed.
6.2 Practice D3271 covers analysis of the solvents by
injection of the liquid coating into a gas chromatograph.
Prior separation is not required.
ANALYTICAL METHODS
7. Heavy Metals Analysis, ASTM Methods
7.1 Methods for the analysis of pigments apply to dry pigment or to pigment separated from the vehicle in accord ance with Section 5.
7.2 Lead: 7.2.1 Pigment Analysis--In all the following methods except for Methods D2742, the concentration range for which the method is applicable is not given.
10Occupational Safety and Health Reporter, Section 1910.1000 Table Z.l.
7.2.1.1 Methods D49 cover procedures for the chemical
analysis of dry red lead having the approximate formula Pb304 (probably Pb02-2Pb0). Total lead is determined gravimetrically as lead sulfate.
7.2.1.2 Test Methods D 126--Total lead is determined gravimetrically as lead sulfate. The comparable Fed. Test Methods Std. 141 methods are 7271 and 7281.
7.2.1.3 Methods D215--Two methods are described for the gravimetric determination of total lead, one as the sulfate and the other as the chromate. The choice of method may be dictated by potential interferences discussed in the text.
7.2.1.4 Test Methods D 1301 cover procedures for the
chemical analysis of basic carbonate white lead and basic sulfate white lead. Total lead is determined gravimetrically as lead chromate. The comparable Fed. Test Method Std. 141 method is 7041.
7.2.1.5 Test Methods D 1844--Total lead is determined gravimetrically as lead chromate.
7.2.1.6 Methods D 2742--Silicon is removed by filtration and total lead determined gravimetrically as lead sulfate. The methods are designed for the analysis of essentially pure pigment.
7.2.1.7 Methods D 3280 cover procedures for the analysis of white zinc pigments, including leaded zinc oxide. Total lead is determined gravimetrically as lead sulfate.
7.2.2 Analysis ofLiquid Material or Dried Film: 7.2.2.1 Test Methods D564 cover the determination of percent lead in liquid driers (see Section 9). Total lead is determined gravimetrically as lead sulfate. The comparable Fed. Test Method Std. No. 141 method is 7231. 72.2.2 Test Method D 2374 covers a titrimetric determi nation of lead in paint driers that can be dissolved in a suitable solvent and utilizes excess EDTA (ethylene diamine tetraacetic acid) to react with lead and cupric sulfate to back titrate. The drier is dissolved in glacial acetic acid, diluted with isopropyl alcohol and water, and treated with an excess of standard EDTA solution. The excess is titrated with standard cupric sulfate solution using an indicator. The
method includes a precision statement but the applicable concentration range is not given.
7.2.2.3 Test Method D 3335 covers the determination of lead contents between 0.01 and 5 % present in the solids of liquid coatings or in dried films. A specimen of liquid paint or dried film is prepared for analysis by dry ashing. The lead content of an acid extract of the ash is determined by atomic absorption spectroscopy. The precision statement is based on a relative scale.
7.2.2.4 Test Method D 3618 is intended as a screening test to determine if a sample of paint solids contains more than
0.5 % lead. The test will barely detect the presence of 0.4 % and will give a definite test at the 0.5 % level. The specimen is dry ashed and extracted. Lead present is oxidized to lead peroxide and, spotted with "tetrabase" to develop a blue coloration. Higher or lower concentrations may be detected by this test method by making appropriate changes in the specimen size and reagent quantities.
7.3 Chromium: 7.3.1 Pigment Analysis: 7.3-. 1.1 Test Methods D 126--In these test methods the chromium content of pigments is only calculated as Cr203 for chromium oxide green. For chrome oranges, yellows, and
545
DUP0502 97726
D 3630
greens the chromium is calculated as lead'chromate.
7.3.1.2 Test Methods D444 cover procedures for the
chemical analysis of the pigment known commercially as "zinc yellow" or "zinc chromate yellow." Total chromium in the pigment is determined by titration using either the dichromate method or the thiosulfate method and calculated as Cr03.
7.3.1.3 Test Methods D 1844--Total chromium in the pigment is determined as chromium trioxide by titration using the thiosulfate method.
7.3.1.4 Test Methods D 1845--Total chromium in the pigment is determined as chromium trioxide by titration
using the thiosulfate method. 7.3.2 Analysis ofLiquid Paint or Dried Film: 7.3.2.1 Test Method D 3718 covers the determination of
chromium or chromium compounds (including chromium
oxide) when present in the solids of liquid coatings or in dried films in the concentration range from 0.005 to 1.0 % (50 to 10 000 ppm) expressed as chromium. A specimen of liquid paint or dried film is prepared for analysis by dry ashing. A weighed quantity of the ash is digested with potassium permanganate and sulfuric acid. Chromium is
determined on the filtered digestion mixture by atomic absorption spectroscopy.
7.4 Barium: 7.4.1 Pigment Analysis: 7.4.1.1 Methods D215--Soluble barium is determined gravimetrically as the sulfate. 7.4.1.2 Test Methods D 715--Applicability to mixed pig ments when barium is a minor component is not indicated. 7.4.1.3 Methods D 3280 cover procedures for the analysis of white zinc pigments. Determination of total barium
sulfate content is described in Section 20 of Methods
D 3280. 7.4.2 Analysis of Liquid Paint or Dried Film--Current
legislation restricts the quantity of "soluble" barium in coatings used in areas accessible to children, but the condi tions of solubility are not usually defined. There is no ASTM method for soluble barium; see Section 10.
7.5 Mercury: 7.5.1 Analysis of Liquid Paint or Dried Film--Test Method D 3624 covers the determination of mercury con
tents between 10 and 1000 ppm in liquid coatings and dried films. The specimen of whole paint, paint vehicle, or dried film is digested using sulfuric and nitric adds, and the concentration of mercury determined using cold-vapor atomic absorption.
7.6 Arsenic: 7.6.1 Analysis of Liquid Paint or Dried Film--Test Method D 2348 covers the determination of less than 0.5 %
arsenic in liquid coatings or dried films. Whole paint or dried film is digested in nitric and sulfuric add. Sodium chloride is added and the arsenic trichloride distilled. Total arsenic is determined by titration with potassium bromate.
7.7 Antimony: 7.7.1 Pigment Analysis: Test Method D 2350--Total an timony is calculated from the antimony oxide content determined by titration with potassium permanganate. The concentration range for which the method is applicable is not given. The comparable Federal Method is 7106. 7.7.2 Analysis of Liquid Paint or Dried Film--Test
Method D3717 covers the determination of antim
contents between 50 and 200 ppm present in the solids^
liquid coatings in dried films. The specimen of liquid
or dried film is prepared for analysis by dry ashing at 5oor

11. Nonvolatile Vehicle Components, ASTM Methods
11.1 Test Method D2621 covers the qualitative charac terization or identification of separated paint vehicle solids by infrared spectroscopy within the limitations of this procedure.
j2. Volatile Components
12.1 The volatile components of protective coatings must be identified to determine compliance with regulations covering labeling, work place concentrations, and air quality standards.
12.2 Gas chromatography is widely used for this purpose. However, owing to the empirical nature of the technique, chemical or instrumental confirmatory tests may be neces sary as supplementary procedures.
12.3 Identification of the components of an unknown solvent blend would in many cases be expedited by means of a combination ofgas chromatography and infrared spectros copy or mass spectrometry.
12.4 Interconnected chromatographic, infrared analyzers are available that separate multicomponent mixtures into their pure components for infrared analysis.
12.5 Analysis of the volatile component of whole paint has been covered in Section 6.
12.6 The following ASTM methods cover the analysis of some of the volatile components of protective coatings currently subject to regulation as potentially hazardous materials:
12.6.1 Method D2349 covers the determination of the nature of thinner in solvent-reducible house paints con taining only hydrocarbon solvents.
12.6.2 Test Method D 3432 covers low molecular weight urethane products containing (a) 0.1 to 1.0 % and (b) 1.0 to 10 % of free toluene diisocyanate (TDI) content.

6.4 Hydrochloric Acid (sp gr 1.19)--Concentrated hydro chloric acid (HC1).
6.5 Stannous Chloride Solution (400 g/L in HC1)--Dis solve 40 g of tin (II) chloride (SnCl2) in 50 mL of HC1 (sp gr 1.19). Transfer to a 100-mL volumetric flask and fill to the ,jiark with concentrated HC1.
7. Hazards
7.1 Use care in handling concentrated HCI because it is corrosive and may cause bums to the skin and eyes and its vapor is irritating to mucous membranes. Refer to suppliers' Material Safety Data Sheet.
7.2 Use only a rubber bulb aspirator for pipetting liquids.
g. Calibration and Standardization
8.1 Prepare 100-mL quantities of at least four standard solutions bracketing the expected antimony concentration in the sample to be tested. To suitable aliquots of the 0.1 mg/mL standard antimony solution, add 40 mL of concen trated HCI and 8 drops of SnCl2 solution. Dilute to 100 mL with water. Prepare a blank solution by diluting 40 mL of concentrated HCI and 8 drops of SnG2 solution to 100 mL with water.
8.2 Operational instructions for atomic absorption spectrophotometers vary with different models. Consult the manufacturer's literature for establishing optimum condi tions for the specific instrument used.
8.3 Turn the instrument on and set the wavelength to the 217.6-nm antimony line. Apply the recommended current to the antimony source lamp. Allow the instrument to warm up for about 15 min and set the slit width. Adjust the air and acetylene pressures and ignite the burner in accordance with instructions.
8.4 Aspirate water to rinse the atomizer chamber. Aspi rate a standard solution and make any necessary readjust ment in instrument parameters to obtain maximum absorp tion.
8.5 Aspirate the blank solution. When the recorder, meter, or other readout device reaches a constant value, it should be immediately zeroed. Repeat this blank determina tion until a steady, repeatable zero value is obtained at the maximum response.
8.6 Aspirate each of the appropriate standard solutions in ascending antimony concentrations and record the corre sponding instrument readings. Aspirate water between each standard
N01' 1--A deuterium background corrector, if available, should be
used to correct for background absorption. If not available, it is necessary to reaspirate each standard solution and measure the back ground at a nearby nonabsorbing region of the spectrum.
N23' 2--Because of the high concentration and corrosive nature of
the acids used for the analysis, it is essential that the burner assembly be disassembled and thoroughly cleaned out immediately after the analyses are completed. Consult the instrument manual for cleaning instructions.
8.7 Construct a calibration curve on linear graph paper by plotting the absorbance (corrected for background) versus concentration (micrograms per millilitre) for each standard solution.
9. Procedure
9.1 If the sample is a liquid coating, mix it until homoge neous, preferably on a mechanical paint shaker. Determine the nonvolatile content in accordance with Guide D 2832.
9.2 Prepare at least two replicate samples by weighing by difference from a dropping bottle or syringe, 5 to 10 g of the mixed liquid coating, or by directly weighing approximately 2 to 6 g of dried film, into 125-mL Erlenmeyer flasks. Weigh to the nearest 0.1 mg.
N45' 3--The specimen size called for will have a concentration of
approximately 4 to 12 gg/mL antimony in the final diluted solution for paints containing approximately 200 ppm (mg/kg) antimony based on the nonvolatile content, and 1 to 3 pg/mL for paints containing approximately 50 ppm antimony, based on the nonvolatile content.
N01' 4--Recover dried paint films from previously coated substrates
(being careful not to remove any underlying material from the substrate) or prepare in the laboratory from liquid samples. For the laboratory preparation, flow some of the well-mixed sample onto a clean glass plate. The use of a paint draw-down bar is recommended to obtain a uniform film thickness not exceeding 2 mils (50 pm). Allow the film to dry in an oven at 105C for a minimum of I h. Scrape the dried film off the glass plate, preferably with a single-edge razor blade.
9.3 Place the flasks containing the liquid coating on the
hot plate and slowly increase the temperature until the material is dried.
9.4 When the sample appears to be dry, or when starting with a dried film, gradually increase the temperature of the hot plate until the material chars.
9.5 After charring appears complete, place the flasks in the muffle furnace and ash at 500C. When the ashing appears to be complete (approximately 1 to 2 h), remove the flasks from the muffle furnace and allow to cool to room temperature.
9.6 Carefully add 40 mL of concentrated HO and 8 drops of SnCl2 solution to each flask. Connect the flasks to water-cooled condensers and reflux for 1 h.
9.7 Filter each digested specimen through medium-po rosity filter paper into a 100-mL volumetric flask. If the filtrate is not clear, refilter through fine-porosity filter paper. Rinse each flask several times with water, adding the rinsings to the filter paper. Wash the filter paper several times with water. Adjust the volume to 100 mL with water and mix.
9.8 Aspirate each test solution and determine the absorbance in the same manner in which the instrument was calibrated (see Notes 1 and 2). Determine the concentration of antimony in micrograms per millilitre from the calibra tion curve. If the absorbance is above the range covered by the calibration curve, dilute an aliquot of the test solution to a suitable volume with water containing 40 mL of HCI and 8 drops of SnCl2 solution per 100 mL. If the absorbance is below the range covered by the calibration curve, repeat the analysis using a larger specimen size.
N67' 5--Increased sensitivity may be obtained with instruments
possessing scale expansion and concentration readout capability.
N45' 6--The method of standard additions may be used to improve
the accuracy of the analysis. This method is particularly recommended for use with unknown samples where matrix effects may be potentially significant For a detailed description of the procedure and calculations used in the method of standard additions, consult a standard text on atomic absorption spectroscopy or the instruction manual provided by the instrument manufacturer.

12; Precision and Bias5
12.1 The precision estimates are based on an inter laboratory study in which eight different laboratories ana[ lyzed in duplicate, on two different days, three samples of water-reducible paints and three samples ofsolvent-reducible paints containing from 50 to 200 ppm (mg/kg) antimony The within-laboratory coefficient of variation was found t0 be 4.8 % relative at 31 degrees of freedom and the betweenlaboratory coefficient of variation was 8.8 % relative at 25 degrees of freedom. Based on these coefficients, the following criteria should be used forjudging the acceptability of result at the 95 % confidence level:
12.1.1 Repeatability--Two results,-each the mean of duplicate determinations, obtained by the same operator on different days, should be considered suspect if they differ by more than 14 % relative.
12.1.2 Reproducibility--Two results; each the mean of duplicate determinations, obtained by operators in different laboratories, should be considered suspect if they differ by more than 26 % relative.
12.2 Bias--The mean of duplicate determinations within any laboratory should be within 18 % relative of true value.

N:;' 1--To obtain maximum accuracy one should complete caK,
bration and standardization just prior to sample analysis.
9. Procedure
9.1 If the sample is a liquid coating, mix it until homog. neous, preferably on a mechanical paint shaker. Determine the nonvolatile content in accordance with Guide D 2832.
9.2 Determine the ash content of the material under test in duplicate.
9.2.1 Weigh to the nearest 0.1 mg approximately 5 g of liquid coating or 3 g of dried film into each of two tared porcelain crucibles.
N<=' 2--Recover dried paint films from previously coated sub
strates (being careful not to remove any underlying material from the' substrate) or prepare in the laboratory from liquid samples. For the laboratory preparation, flow some of the well-mixed sample onto a clean glass plate. The use ofa paint draw-down bar is recommended to oblaih a uniform film thickness not exceeding 2 mils (50 pm). Allow the film tedry in an oven at 105"C for a minimum of 1 h. Scrape the dried film oft the glass plate, preferably with a single-edge razor blade.
9.2.2 Place the crucibles containing the liquid coating on the hot plate and slowly increase the temperature until the material is dried. With some types of coatings, an initial:' oven-drying at 105C may be necessary to remove solvents without incurring losses due to spattering.
9.2.3 When the specimen appears to be dry, of when starting with a dried film, gradually increase the temperature of the hot plate until the material chars.
9.2.4 After charting is complete, place the crucibles in the muffle furnace and ash at 500"C.
9.2.5 When the ashing appears to be complete (approxi mately 1 to 2 h), remove the crucibles from the muffle furnace and allow to cool to room temperature in a desiccator. Weigh and calculate the mean value for the percent ash.
9.3 Transfer each ash to a clean, dry mortar and grind to a fine, uniform powder. Weigh to the nearest 0.1 mg, 0.02 to 0.2 g of each ash directly into separate decomposition vessel inserts.
N:;' 3--For a material containing 50- ppm <mg/kg) of chromium
based on the solids and having 50 % ash and 70 % nonvolatile material, 0.2 g of ash extracted and diluted to 50 mL will contain 0.28 pg of chromium per millilitre, and for one containing 10 000 ppm, 0.02 g of ash extracted and diluted to 100 mL will contain 2.8 jrg of chromium per millilitre. To ensure complete recovery of chromium, do not use more than 0.05 g of ash for materials that are known or suspected to contain over 1000 ppm of chromium based on the solids.
9.4 Pipet exactly 10 mL of oxidizing solution into the cup. Swirl gently to facilitate mixing. Place , the vessel in a circulating oven at 105C for IV2 h.
9.5 Remove the vessel from the oven and allow to cool slowly to ambient temperature. Do not cool by placing the vessel in a refrigerator or freezer, or by submerging it in a

Rinse the digestion cup several times with water, transferring any insoluble material to the filter paper. Wash the filter paper several times with small volumes of water. Add hydroxylamine hydrochloride solution dropwise to the filtrate until the permanganate color has been discharged, then dilute to volume with water.
9.7 Aspirate each test solution and determine the ab sorbance in the same manner in which the instrument was calibrated. Determine the concentration of chromium in micrograms per millilitre from the appropriate calibration curve. If the absorbance is above the range covered by the calibration curve, dilute an aliquot of the test solutions to a suitable volume with H2S04 (5 % volume per volume) and repeat the determinations.
N@A' 5--The method of standard additions may be used to improve
the accuracy of the analysis. This test method is particularly recom mended for use with unknown samples where matrix effects may be potentially significant. For a detailed description of the procedure and calculations used in the method of standard additions, consult a standard text on atomic absorption spectroscopy or the instruction manual provided by the instrument manufacturer,
10. Calculation
10.1 Calculate the mean concentration of chromium in the nonvolatile portion of the sample as follows:
Chromium, ppm (mg/kg) in nonvolatile
= (CxFx Ax V)/(S x NV)
where: C = concentration of chromium in the aspirated test
solution, jig/mL, F = dilution factor from 9.7 (volume diluted to volume
of aliquot),
A = mean percent ash as determined in 9.2.5, V = volume diluted to in 9.6 (50 or 100 mL), S = weight of ash, and NV = percent nonvolatile of paint sample (use 100 if
sample was a dried film).
11. Report
11.1 Report the chromium content of the nonvolatile portion of the sample tested and whether the analysis was conducted on a liquid coating or a dried film.
12. Precision and Bias7
12.1 The precision estimates are based on an inter laboratory study in which six different laboratories analyzed in duplicate, on two different days, four samples of waterreducible paints and four samples of solvent-reducible paints containing from 50 to 10 000 ppm (mg/kg) chromium. The within-laboratory coefficient of variation was found to be 4.9 % relative at 39 degrees of freedom and the betweenlaboratory coefficient of variation was 8.5 % relative at 31 degrees of freedom. Basal on these coefficients, the following criteria should be used forjudging the acceptability of results at the 95 % confidence level:
12.1.1 Repeatability--Two results, each the mean of du plicate determinations, obtained by the same operator on different days should be considered suspect if they differ by more than 14 % relative.
12.1.2 Reproducibility--Two results, each the mean of duplicate determinations, obtained by operators in different laboratories should be considered suspect if they differ by more than 24 % relative.
12.2 Bias--The mean of duplicate determinations within any laboratory should be within 17 % relative of true value.

" NBC' --Section 9 was added editorially in May 1990.
1. Scope 1.1 This test method covers a procedure for the pigment
content determination of water-based paints. It is' applicable only to pigments that do not decompose or lose weight at temperatures below 500C. Such pigments include most metal oxides, silicates, and a majority of anhydrous inor ganic salts.
1.2 Many water-based paints contain pigments and or ganic colorants that lose water of hydration or decompose at this temperature. The residual ash should be carefully inspected for changes in color or texture that could indicate a pigment alteration and hence lead to erroneous results. Caution should therefore be exercised when applying this test method to samples containing unknown pigment composi tions.
1.3 This standard does not purport to address the safety problems associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

6. Procedure
I
sh 9f
6.1 Mix samples until homogeneous, preferably on a I
mechanical shaker. If air bubbles become entrapped in a 1
sample, stir it by hand.
6.2 Draw approximately 1.5 g of the test paint into a
R:
5-mL syringe and weigh to 1 mg. Add the paint dropwise
(about 30 drops) into a tared-aluminum foil dish that con
tains 2 mL of water (5.2). Swirl the dish during the addition
and continue the swirling until the specimen is completely
dispersed. Reweigh the syringe to 1 mg. Transfer between 0.4
and 0.6 g of sample to the dish. If not, adjust the transferred
volume and prepare a new specimen. If the specimen ag
glomerates or forms a lump that cannot be dispersed, a drop
or two of ammonia (5.3) may facilitate the dispersement. If
the lumping persists, discard the specimen and prepare a new
one. Prepare a duplicate specimen in the same manner.
6.3 Dry the specimen and dishes in the 105 2C oven
for a minimum of 1 h after making certain that the dishes are
level. Ifthe coating does not uniformly cover the bottom of a
dish, prepare a new specimen and repeat.

5 Supporting data are available from ASTM Headquarters. Request RlfcDOl.lOM.
8.1.1 Repeatability--Two results obtained by the same operator should be considered suspect if they differ by more than 0.66 % absolute.
8.1.2 Reproducibility--Two results, each the mean of duplicate determinations, obtained by operators in different laboratories should be considered suspect if they differ by more than 1.05 % absolute.
8.2 Bias: Pigment Content--On the basis of the same study, the mean of two determinations should be within 5 % relative of the formula pigment content of a waterborne paint containing only inorganic pigments.
8.3 Precision: Nonvolatile Content-- On the basis of an interlaboratory test of this test method in which fourteen operators in seven laboratories analyzed three materials containing three nonvolatile levels between 43 and 48 %, the within-laboratory standard deviation was found to be 0.18 % absolute and the between-laboratories standard deviation was found to be 0.445 % absolute. Based on these standard deviations,the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
8.3.1 Repeatability--Two results obtained by the same operator should be considered suspect if they differ by more than 0.49 % absolute.

Designation: D 3730 - 78 (Reapproved 1088)'61
An American National Standard
Standard Guide for Testing High-Performance Interior Architectural Wall Coatings1
This standard is issued under the fixed designation D 3730; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval A superscript epsilon (<) indicates an editorial change since the last revision or reapproval
il NFG' --Editorial changes were made throughout, including the title, in October 1988.
1. Scope
1.1 This guide covers the selection and use oftest methods for high-performance interior architectural wall coatings (HIPAC) that differ from more conventional coatings in that they are tougher, more stain-resistant, more abrasion-re sistant and, ordinarily, designed to be applied to wall surfaces of steel, masonry (poured concrete, concrete block, or cinder block), and plaster or gypsum wallboard. The tests that are listed in Tables 1 and 2 are designed to measure performance properties. These tests may not all be required for each HIPAC system. Selection of the test methods to be followed must be governed by experience and the requirements in each individual case, together with agreement between the purchaser and the seller.
1.2 High-performance architectural coatings are tough, extra-durable organic coating systems that are applied as a continuous (seamless) film and that cure to a hard finish. The finish can be high gloss, semigloss, or low gloss as desired. These coatings are resistant to persistent heat, humidity, abrasion, staining, chemicals, and fungus growth. They are used in areas where humidity, wear, or unusual chemical resistance requirements, particularly to soiling, are required and where strong detergents are used to maintain sanitary conditions. Halls and stairways in public buildings, lavatories, stall showers, locker areas, animal pens, and biological laboratories are typical applications. In addition, food processing plants, dairies, restaurants, schools, and transport terminals frequently use HIPAC systems. These are effective in many areas of building interiors compared with tile and are of low materials and maintenance costs. HIPAC systems should be used as a complete system only as recommended by the manufacturer since the individual coats in a system are formulated to be compatible with each other. HIPAC systems should be applied only to properly prepared surfaces such as steel and masonry that includes cinder blocks and cement blocks. They can be applied over plaster and gypsum wallboard. Ordinarily, a prime or fill coat, if required, is part of the system.
1.3 While they are excellent for walls, HIPAC are not usually intended for ceilings and floors. They would not ordinarily be used in homes, although parents with small children might want to use HIPAC coatings on some walls.
1 This method is under the jurisdiction of ASTM Committee D-l on Faint and Related Coatings and Materials, and is the direct responsibility of Subcommittee DO 1.42 on Architectural Finishes.
Current edition approved Dec. 21, 1978. Published January 1979.
1.4 The types or resin ordinarily used are the following; epoxy-polyamide, two-package; polyester-epoxy type, two. package; polyurethane, one-package or two-package. However, other resin types are not excluded provided they can meet the requirements (performance specifications) laid down by the purchaser.
1.5 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Definitions
3.1 For definitions of terms used in these practices, refer to Definitions D 16.
4. Conditions Affecting Performance of HIPAC Coating Systems
4.1 Practical requirements for high performance coatings may vary with:
4.1.1 Substrate type such as concrete, poured or precast block, lime-gypsum plaster, etc.
4.1.2 Climatic conditions, both generally and specifically, at the time of coating application. ASTM standard condi tions for laboratory testing are 73.5 3.5F (23 2C) and 50 5 % relative humidity.
5. Sampling
5.1 Prior to sampling, establish the condition of the container since damage to it may cause evaporation, skin ning, or other undesirable effects. Excessive storage time and temperature fluctuations may cause settling or changes in viscosity.
5.2 Sample the coating in accordance with the Practice E 300. Determine the weight per gallon or kilogram per litre in accordance with Test Method D 1475 and repeat until two successive readings agree within 0.2 lb (90 g) or as agreed upon between the purchaser and the seller. Samples for testing may then be taken.
5.3 Specify the amount of the sample, the package sizes, and identification codes to assure a representative sample. A 1-gal (3.8-L) sample is usually sufficient for the recom mended tests but the practice gives sample size in relation to quantity and size of container.
6. Laboratory Tests
6.1 Preparation of Test Panels: 6.1.1 Unless otherwise specified, test panels shall be \xh by 71/2 by 15!/2-in. (38 by 190 by 395-mm) masonry units made from either standard lightweight concrete block, having an apparent specific gravity of 1.60 to 1.62 or smooth asbestos cement board complying with Specification C 220. 6.1.2 One face only of the test panel shall be coated with the complete system, in a vertical position. For concrete, the filler shall either comply with U.S. Federal Specification TT-F-1098 or be the. material specified and supplied by the manufacturer. The filler coat shall be applied in conform ance with the manufacturer's printed directions for surface preparation, mixing, application, coverage, and curing time under standard conditions of temperature and humidity.
7. Liquid Coating Properties
7.1 Condition in Container--Thickening, settling, and separation are undesirable and objectionable if a coating, after storage, cannot be readily reconditioned and made suitable, for application with a reasonable amount of stirring. The referenced method covers procedures for determining changes in. properties after storage. Determine the condition in the container in accordance with Method 3011 of Federal

Test Method Standard No. 141. 7.2 Coarse Particles and Foreign Matter--Coatings must
be free of oversize particles and foreign matter to form a uniform film of good appearance, a typical maximum being 0.5 weight % of total coating. The specified test with a No. 325 (45-jim) screen gives the percent of these particles in a material. Determine coarse particles and foreign matter in accordance with Test Methods D 185, Section G.
7.3 Density or Weight Per Gallon--The density of a coating as measured by weight per gallon is used to assure product uniformity from batch to batch and provides a check against the theoretical weight calculated from the formula. The referenced test method gives a procedure for measurement of the density of a liquid coating. The density is expressed as weight in pounds per 1 U.S. gal or in kilograms per litre of the coating at a specified temperature. A calibrated weight-per-gallon cup is used. Determine weight per gallon in accordance with Test Method D 1475.
7.4 Fineness of Dispersion--One method for measuring the degree of dispersion is to draw a liquid coating down in a tapered groove in a hardened steel block with a groove varying in depth from 4 to 0 mils (100 to 0 pm). The point at which continuous groupings of particles or agglomerates, or both, protrude through the surface of the wet film is taken as
the fineness reading. Lower readings in mils or micrometers or higher readings in Hegman units indicate better disper sion. A typical fineness of dispersion requirement is a reading of 1.5 mil (38 pm) or 5 Hegman for HIPAC. Determine fineness of dispersion in accordance with Test Method D 1210.
7.5 Odor--Adequate ventilation is required as some sol vent combinations produce obnoxious odors. Test for odoi in accordance with Test Method D 1296.
NHI' : Warning--Even though the odor may be pleasant, the fumes
may be dangerously toxic.
7.6 Consistency--Coatings of a given type should fall within a consistency range agreed upon. In the referenced test method, consistency is defined as the load in grams required to produce a specified rate of shear. A typical range is 85 to 135 Krebs unit (KU) for base coats and 70 to 95 KU for glaze coats. Determine the consistency of the product in accordance with Test Method D 562.
7.7 Dilution Stability--The diluent suggested for reduc tion should be readily incorporated into the coating without excessive stirring or shaking. This test is a measure of the stability of a coating that has been reduced to a desired viscosity, for example, for spray application. Determine

Test Method Standard No. 141.
7.8 Flash Point--Organic solvents used in coatings have characteristic temperatures at which they will support com bustion. This temperature is known as the flash point. It is
often used for danger classification in shipment by common carriers. It is also used to determine conditions of storage to meet fire regulations and also the safety requirements of the Occupational Safety and Health Act (OSHA). This tempera ture is not directly translatable as the danger level when applied as films to surfaces. Determine the flash point in accordance with Test Methods D 93, when in closed or open cups---
7.9 Free Diisocyanate Content--It is generally recognized that diisocyanate vapors from polyurethane-type HIPAC coatings are potential health hazards. Therefore, the free diisocyanate content of urethane coating systems must be controlled at an acceptable maximum level, the present accepted maximum being 0.5 % based on total coating
weight, which is applicable only to toluene diisocyanate (TDI) and hexamethylene diisocyanate (HMDI). It has not been shown that this level is applicable to all diisocyanates. Determine free toluene diisocyanate content in accordance with Test Method D 2615. There is no ASTM test method applicable for the other diisocyanates, but test methods are now being developed by ASTM. The presence of free HMDI can be determined by the method described in Appendix I of U.S. Military Specification MIL-C-83286.
7.10 Volatile Content (Weight Percent)--The percent of volatile matter indicates the thinner loss from the film as it dries. Calculate the volatile content of the coating by difference after determining the nonvolatile content in accordance with Test Methods D 1644.
S. HIPAC Application and Film Formulation
8.1 Application by Brush--Brushed films should be smooth and free of seeds and on vertical surfaces should show no sagging, color streaking, or excessive brush marks. Test application or brushed films in accordance with Method 2141 of Federal Test Method Standard No. 141.
8.2 Application by Roller--Walls are frequently painted with rollers that produce slight stipple effects. Test roller coating properties in accordance with Method 2112 of Federal Test Method Standard No. 141.
8.3 Application by Spray--Interior coatings are some times applied by spray. Both air and airless spray are used in commercial work. Test in accordance with Method 2131 of Federal Test Method Standard No. 141.
8.4 Leveling Properties--Leveling is a factor in hiding and appearance of coatings. The referenced test method covers the laboratory determination of the relative leveling charac teristics of liquid coatings. Determine leveling property in accordance with Test Method D 2801.
~ 8:5 Working-Properties--Working properties of a coating are generally compared to a standard or described by requirement in the product specification. Test working

properties in accordance with Method 4541 of Federal Test Method Standard No, 141.
8.6 Sag Resistance--Some coatings sag and form curtains before the film sets. Test for sag resistance in accordance with Method 4494 of Federal Test Method Standard No. 141.
8.7 Wet Film Thickness--Measurement of wet film thick ness is useful in calculating spreading capacity or adjusting application to an agreed upon square feet per gallon or square metres per litre. Determine wet film thickness in accordance with Test Methods D 1212.
8.8 Producing Films of Uniform Thickness--The fol lowing test method covers the preparation of enamel films of uniform thickness essential in conducting various tests. Prepare films in accordance with Test Methods D 823.
8.9 Curing Time--The cure of a HIPAC system is gov erned by the composition of the coating and by atmospheric conditions during cure. Insufficient cure may result in poor stain and abrasion performance. Typical cure times are between 3 and 21 days depending upon the system. There are no applicable ASTM or Federal test methods to measure cure of HIPAC systems, but one method used is as follows:
8.9.1 After the final cure for the duration specified by the manufacturer, place 10 drops of acetone on the coated surface and cover with a 25-mm watchglass. After 3 min lift the watchglass and remove the acetone by blotting. Allow a recovery period of 1 h and examine for evidence of softening or wrinkling of the coating.
9. Appearance of Dry Coating
9.1 Color Difference--Visual comparison of color is fast and often acceptable, although numerical values are not obtained. However, the appearance of a color is greatly influenced,by several factors.
9.1.1 A color next to a yellow wall will look different than the same color next to a blue wall. The same color illuminated by incandescent light, fluorescent light, and natural northern light, will appear to be different because the spectral makeup of the incident lights vary.
9.1.2 Gloss also affects color appearance. The same color with a low gloss and high gloss will usually appear to differ, although instrumentally the colors may be identical. The reason is that the color seen is different when the incident light is unevenly scattered by the rougher surface of the low-gloss finish. Often times, the paint manufacturer is expected ^to produce color matches for all sorts of incident conditions. Hence, the method given in Method 4250 of Federal Test Method Standard No. 141 provides a reason ably accurate method of visual comparison using natural northern light as the incident source. Where a more accurate method of visual comparison is desired,. Practice- D 1729 should be employed since it specifies the composition of the incident light.
9.1.3 Determination of color difference by instrument in accordance with Method D 2244 is the more reproducible, but visual perception is the more nearly related to the needs in actual use,' where the conditions are unpredictable but may be expected to include many types of lighting.
9.2 Directional Reflectance--This is an important prop erty of a white coating as. it is a measure of the brightness of the surface. Frequently the reflectance of a white coating
may- be reduced to increase hiding power. To maintain jpice). To 1

10. Properties of Dry Coatings
10.1 Abrasion Resistance--Wear resistance of HIPAC coatings is one of the outstanding qualities which distin guishes them from ordinary interior wall and trim enamels.
Determine abrasion resistance in accordance with Method 6192 of Federal Test Method Standard No. 141.
10.2 Adhesion--Adhesion is the property of the film that resists removal from the substrate when scuffed or scraped and is an important property in a HIPAC system. There are no applicable ASTM or Federal test methods to measure adhesion of HIPAC systems, but one method used is as follows:
10.2.1 Attach heavy screw eyes to one end of each of twelve 1-in. (25-mm) diameter wood or metal dowels aps proximatelyi 1 Vz in. (38 mm) long. Glue the dowels to the cured coating on a test panel at 3-in. (75,-mm) centers, using
a cold-curing epoxy adhesive applied to both the coating and the dowel. Make sure that the button of adhesive does no! extend beyond the diameter of the dowel or the area will be larger than intended. After conditioning for 3 days at 73.5* 3.5F (23 2C), slowly apply an axial pull of 150 lbf (68ff j N) to each of three dowels. The force may be applied by any method having an accuracy of 5 %, such as by a system of weights and pulleys or through a spring scale (spring

ance). To prevent injury should the dowel come loose, provide a suitable guard by placing over the dowel a length of
pipe having a cap at one end and a drilled hole in the cap through which to apply the force. Failure is defined as removal of at least one of the three dowels due to separation between the test panel and the top or glaze coat(s). If failure occurs between the adhesive and the coating, test an addi
tional dowel. 10.2.2 If the above portion of test is passed, place the test
panel coated side up in a pan containing water maintained at 73.5 3.5F (23 2C). Keep about 0.5 in. (13 mm) of water in contact with the uncoated portion of the panel. At the end of 7 days, pull three more dowels, using a force of 20 lbf (90 N). Dry the coating for 24 h and pull three more dowels, using a force of 30 lbf (135 N).
10.3 Chemical Resistance--An important property of a HIPAC system is its ability to resist spotting, softening, or removal when subjected to household chemicals or strong
cleaners. There is no applicable ASTM or Federal test method specifically designated for measuring resistance of HIPAC systems to chemical and cleaning agents, but Test
Method D 1308 has been modified as follows: Prepare 5 weight % solutions of sodium hydroxide, sodium hypo chlorite, detergent, hydrochloric acid, sodium phosphate, and sulfuric acid. For each solution saturate a small piece of absorbent cotton, place them on the cured surface, and cover with a 25-mm watchglass. After 4 h, remove, blot dry, allow to recover for 24 h, and examine the exposed surface of the coating for evidence of softening or wrinkling.
10.4 Coating Thickness--Measure total dry film thick ness from the top of the substrate to the top of the applied coating system. When applied to steel, use Test Methods D 1186. When applied to nonmagnetic surfaces, use Test Methods D 1005 if the surface is plain and rigid.
10.5 Flame Spread Test--For some uses HIPAC coatings should not increase fire hazard. Where required, determine the flame spread and smoke development rating in accord ance with Test Method E 84.
10.6 Fungus Resistance--Since HIPAC coatings may be used in food processing plants and locations of high hu midity, they should be resistant to mold growth on the surface. For this test, an environmental chamber is needed. Determine the resistance to mold growth in accordance with Test Method D 3273.
10.7 Heat and Cold Resistance--Buildings can undergo cycling of temperatures that could, through differential thermal expansion between the coating and the masonry
substrate, cause failure. There is no applicable ASTM or Federal test methods specifically designated for measuring resistance of HIPAC systems to cold and heat cycles but Test Method D 1211 has been modified as follows:
10.7,1 Place coated panels of the substrate of interest in a cold chamber maintained at 5F (-21C) for 1 h. Remove and immediately place in an oven maintained at 120F (49C) for 1 h. Repeat this cycle 10 times and examine the coating for cracks, checks, or other defects.
10.8 Heat and Humidity Resistance--HIPAC coatings can be subjected to environmental conditions where high heat and humidity are present. There is no applicable ASTM or Federal test method specifically designated for measuring resistance of HIPAC systems to heat and humidity but
Practice D 2247 has been modified as follows:
10.8.1 Coat panels with the complete system and expose to an environment of 95 % relative humidity minimum, and I40F (60"C) for 7 days in an enclosed cabinet. Determine the 60-deg gloss before and after by Test Method D 523 and color change by Method D 2244.
10.9 Impact Resistance--An important property of HIPAC coatings is their ability to withstand impact when objects are accidentally knocked against them. Determine impact resistance in accordance with Test Method D 2794, except use zinc phosphate-treated steel panels. Some mate rials, such as urethanes, require a wash primer or an epoxy primer to give the adhesion needed for this test. Apply top or glaze coat(s) at a minimum dry-film thickness of 3 mils (75 mm) and examine the surface of the impacted coated area under 7x magnification for cracking and crazing of the coating immediately after testing and 72 h after the test.
10.10 Perspiration Resistance--HIPAC coatings can sometimes come in contact with perspiration that could stain the coating. There are no ASTM or Federal test methods to measure perspiration resistance of HIPAC systems but where considered important the following method can be used:
10.10.1 Prepare synthetic perspiration fluid having the following composition by weight:
Urea
J2( ( 3
Na2SO4-I0H2O NaCl Acetic acid (5 % solution) ' 2o
Anhydrous lanolin
1.30
0.11 0.65 2.71
1.08 10.85 83.30
10.10.1.1 Dissolve the urea and inorganic salts in the acetic acid solution and water. Heat the lanolin to 45C and add the solution to form an emulsion. Combine with a dye and wetting agent in the following proportions:
Scarlet red Methanol Wetting agent Synthetic perspirant
0.1 3.7
3.8 92.4
10.10.1.2 Dissolve the dye in the methanol, then mix with the wetting agent and synthetic perspirant. Apply an excess ofthe mixture to a small area of a test panel, using a 1 in. (25 mm) wide artist's brush. Cover with a 25-mm watchglass and place the panel in an oven at 120 3.5F (49 2C), for 4 h. Remove the panel and allow to cool at room temperature for 1 h. Wipe off the excess with a soft dry cloth. If the stain is not completely removed, subject the panel to not more than 25 cycles of the washing procedure described in Method 6141 of Federal Test Method Standard No. 141. Examine the film under 7x magnification for stain retention.
10.11 Scrubbability--The ability of an interior finish to resist scrubbing is an important property. The referenced method provides a measure of the wet abrasion resistance of a film. However, wet abrasion resistance is not necessarily a measure of how well soils or stains can be removed since some porous materials have good scrubbability but poor stain cleansability. Test the coating for at least 4000 cycles in accordance with Method 6142 of Federal Test Method Standard No. 141 except use smooth cement asbestos board complying with Specification C 220 as substrate. Apply the coating system to be tested in conformance with the manu facturer's printed directions for surface preparation, mixing,

1. Terminology
3.1 Descriptions of Terms Specific to This Standard: 3.1.1 cure--the condition of a coating after conversion to the final state of cure as measured by tests generally related to end-use performance and mutually agreeable to supplier ami purchaser. 3.1.2 ultraviolet curing--conversion of a coating from its application state to its final use state by means of a mechanism initiated by ultraviolet radiation generated by equipment designed for that purpose.
4. Significance and Use
4.1 This practice provides a guide whereby all pertinent variables relating to the ultraviolet cure of a coating are described.
5. Procedure.
5.1 Apply the coating to be cured to the desired substrate at a film thickness typical to that normally used. After approximately the time delay encountered in production pass the coated substrate through the curing equipment and subsequently test for cure, as defined in 3.1.1, using the appropriate methods listed in 5.1.1 through 5.1.11. The most commonly used test methods are listed in 5.1.1 through 5.1.4.
5.1.1 Impact Resistance--Test Method D 2794. 5.1.2 Film Hardness--Test Method D 3363. 5.1.3 Solvent Rub Test--Hold a pad of cheesecloth or other cloth saturated with an agreed-upon solvent, usually methyl ethyl ketone, over two adjacent fingers using a protective covering. Rub the wet pad back and forth across a 100-mm portion of the cured film using vigorous pressure, one forward and one backward movement constituting one double mb. Take the end point as the number of double mbs required to soften or penetrate the film. Fully cured films are normally required to resist a specified number of mbs and the result of the test is given as exceeding the limit or failing the test. 5.1.4 Sandability--Ultraviolet cured fillers are usually judged by their sandability with an agreed-upon grit of paper. This test is often made immediately after the material leaves the ultraviolet processor. 5.1.5 Specifying Properties--Practice D 2336. 5.1.6 Abrasion Resistance--Test Methods D 658 and D968. 5.1.7 Indentation Hardness--Test Methods D 1474. 5.1.8 Adhesion--Test Methods D 2197 and D 3359. 5.1.9 Block Resistance--Test Method D 2793. 5.1.10 Formability--Test Method D 3281. 5.1.11 Stain and Reagent Resistance--Practice D 3023. 5.2 Repeat the application, curing, and testing with fresh material on fresh substrates until the shortest time that yields a cured film is obtained.

Standard Test Method for
Water Content of Water-Reducible Paints by Direct Injection Into a Gas Chromatograph1
This standard is issued under the fixed designation D3792; the number immediately following the designation indicates the year of original adoption or. in the case of revision, the year of iast revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapprovai.
j. Scope 1.1 This test method is for the determination of the total
water content of water-reducible paints. It has been evalu ated for latex systems (styrene-butadiene, poly(vinylacetate)acrylic, acrylic). It has not yet been evaluated for other water-reducible paints but is believed to be applicable. The established working range of this method is from 40 to 55 % water. There is no reason to believe that it will not work outside of this range.
1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appro priate safety and health practices and determine the applica bility ofregulatory limitations prior to use.

3. Summary of Test Method
3.1 A suitable aliquot of whole paint is internally stan dardized with anhydrous 2-propanol, diluted with dimethylformamide, and then injected into a gas chromatographic column containing a porous polymer packing that separates water from other volatile components. The water content is determined from area calculations of the materials pro ducing peaks on the chromatogram.
4. Significance and Use 4.1 With the need to calculate volatile organic content
(VOC) of water-reducible paints, it is necessary to know the water content. This gas chromatographic test method pro vides a relatively simple and direct way to determine water content.

*For isothermal operation set the column temperature at 140*C. After the 2-propanol has cleared the column adjust the temperature to 170C until DMF
clears the column. Reset the temperature to 140C for subsequent runs.
5. Apparatus
5.1 Gas Chromatograph--Any gas-liquid chromato graphic instrument having a thermoconductivity detector may be used. Temperature programming capability is pref erable, but isothermal operations may be adequate. See Table 1.
5.2 Column--The column should be 4 ft (1.22 m) of Vis-in. (3.2-mm) outside diameter tubing of stainless steel, or other suitable material, packed with 60/80 mesh (180 to 250 pm) porous polymer packing material.5 A replaceable glass sleeve, glass wool plug, or other suitable material may be placed on the entrance end of the column to retain any nonvolatile materials. This will minimize sludge buildup in the column.
5.3 Recorder--A recording potentiometer with a full-scale deflection of 1 to 10 mV, full-scale response time of 2 s or less and sufficient sensitivity and stability to meet the requirements of 5.1.
5.4 Liquid Charging Devices--Micro syringes of 10 or 25-fiL capacity.
6. Column Conditioning
6.1 Procedure--The packed column is installed in the gas chromatographic unit leaving the exit end disconnected from the detector. This will prevent any contamination of the detector with the column bleed. Set the helium or nitrogen flow rate at 20 to 30 mL/min if a Vi-in. (3.2-mm) outside diameter column is used. Purge the column 5 or 10 min before heating. Heat the column from room temperature to 200C at 5C/min and hold this temperature for at least 12 h (overnight). At the end of this time, heat the column at
5 Parapak Q, a trademark of Waters Assoc., Inc., Milford, MA, has been found satisfactory. Any other porous polymer packing or other column giving equivalents or superior performance may be used. These products are available from most gas chromatograph suppliers and distributors.

5C/min to 250C (the maximum temperature for this packing) and hold for several hours. Cool the column to room temperature and connect the column detector. Reheat the column to 250C at 5"C/min to observe if there is column bleed. Optimum conditioning of this column may take several cycles of the heating program before a good recorder baseline is achieved.
6.2 Before each calibration and series of determinations (or daily) condition the column at 200C for 1 h with carrier gas flow.
7. Reagents and Materials
7.1 Purity ofReagents--Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chem ical Society, where such specifications are available.6 Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination.
7.2 Purity of Water--Unless otherwise indicated, refer ence to water shall be understood to mean reagent water conforming to Type II of Specification D 1193.
7.3 Carrier Gas--Helium of 99.995 % or higher purity. High-purity nitrogen may also be used.
NNO' I--Care should be taken that any moisture that may be
present in the carrier gas is eliminated through the use of a suitable carrier gas purifier. Trace levels of water will accujjiulate on the column at low oven temperatures and may affect the reproducibility as well as the accuracy of the determination.
7.4 Dimethylformamide (DMF) (Anhydrous) gas chroma tography, spectrophotometric quality (Note 2).
7.5 2-Propanol (Anhydrous) (Isopropanol)--See Note 2. 7.6 Septum Sample Vials, 10-mL capacity with fluorocar bon-faced septa are preferred.
NPQ' 2--Determine the water content of the DMF and 2-propanol
by Karl Fischer titration in accordance with Test Method D 1364. Dry the 2-propanoi if water is found in it or replace with anhydrous grade.
8. Hazards
8.1 Dimethylformamide is hazardous. Check the suppli er's Material Safety Data Sheet (MSDS) before use.
9. Preparation of Apparatus
9.1 Install the column in the chromatograph and establish the operating conditions required to give the desired separa tion (see Table 1). Allow sufficient time for the instrument to reach equilibrium as indicated by a stable base line. Control the detector temperature so that it is constant to within 1C without thermostat cycling which causes an uneven baseline. Adjust the carrier-gas flow to a constant value.
10. Calibration
10.1 Using the information in Table 1 (as a guide), select the conditions of temperature and carrier gas flow that give
the necessary resolution of the components.

estimate of the response factor: 10.2.4.1 Inject the same size aliquot of DMF and 2-
propanol mixture, but without added water, as a blank. Note tlie area of the water peak in the blank.
10.2.4.2 The response factor for water is calculated by ,,ieans of the following equation:
,, W(AH,o ~ S)
where: H = response factor, If. = weight of 2-propanol, ffH o = weight of the water, g. 1 = area of 2-propanol peak, gn0 = area of the water peak, and g 1 = area of the water peak in the blank.
jl. Procedure
11.1 Weigh to 0.1 mg, 0.6 g of water-reducible paint (see Mote 3) and 0.2 g of 2-propanol into a septum vial. Add 2-mL of DMF into the vial. Seal the vial. Prepare a blank containing the 2-propanol and DMF but no paint.
NTU' 3--Check each paint system to be analyzed for interfering
peaks. Coalescing agents do not interfere with this determination.
11.2 Shake the vials on a wrist action shaker or other suitable device for 15 min. To facilitate settling of solids allow the vials to stand for 5 min just prior to injection into the chromatograph. Low-speed centrifugation may also be used.
11.3 Inject a 1-pL sample of the supernatant from the prepared solutions into the chromatographic column. Record the chromatograms using the conditions described in Table 1.
12. Calculations
12.1 Measure the area of the water peak and the 2propanol internal standard peak and multiply each area by the appropriate attenuation factor to express the peak areas on a common basis. Use of an electronic integrator is recommended to obtain the best accuracy and precision. However, triangulation, planimeter, paper cut out, or ball and disk integrator may be used.
12.2 Calculate the water concentration in the paint by means of the following equation:
A, xWpxR where: 4' ,o -- urea of water peak, A, = area of 2-propanol peak, Wt = weight of 2-propanol added, Wp = weight of paint, and
R = response factor determined in 10.2.
12.3 Correction for Water Content ofSolvent: 12.3.1 If the blank indicates the presence of a detectable peak for water in the dimethylformamide used as solvent, make a correction in the calculation. 12.3.2 The water content of the dimethylformamide de termined by either chromatography (10.2.4) or, preferably, Karl Fischer titration (10.2.3) is used to make the correction. Calculate the water content due to the solvent by using the following equation:
H20(S),%=TM^
WP
where: Ws = weight of dimethylformamide, Wp = weight of paint, and P ~ weight % water in DMF
100 12.3.3 The water content of the paint in this case is the difference between the total percent determined in 12.2 and the correction for the solvent water content as determined in 12.3.2.
13. Precision and Bias7
13.1 The precision estimates are based on an inter laboratory study in which nine different laboratories ana lyzed in duplicate on two days four samples of waterreducible paints containing from 40 to 55 % HzO (theoretical). The results obtained were analyzed statistically in accordance with Practice E 180. The within-laboratory coefficient of variation was found to be 1.0 % relative at 34 df and the between-laboratories coefficient of variation 2.6 % relative at 30 df. Based on these coefficients, the following criteria should be used for judging the acceptability of results at the 95 % confidence level.
13.1.1 Repeatability--Two results, each the mean of du plicate deteminations, obtained by the same operator on different days should be considered suspect if they differ by more than 2.9 % relative.
13.1.2 Reproducibility--Two results, each the mean of duplicate determinations, obtained by operators in different laboratories should be considered suspect if they differ by more than 7.5 % relative.
13.2 Bias--Bias has not been determined.

Designation: D 3793 - 89
Standard Test Method for Low-Temperature Coalescence of Latex Paint Films1
This standard is issued under the fixed designation D 3793; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval, A superscript epsilon (f) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers the determination of the comparative coalescence of a series of latex paints by determining the porosity of films dried at standard and at low temperature. Porosity is evaluated with a penetrating medium as in Test Method D 3258.
1.2 The texture of the film, which can affect cleanup, will influence the results of the test. Stain applied to a high-hiding paint will not lower the reflectance as much as the same stain applied to a low-hiding paint of equal porosity. These points must be considered in comparing the different paints.
1.3 This method should be used only for comparative testing within one laboratory, as the numerical results obtained by different laboratories do not usually agree.
1.4 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Test Method
3.1 The test paints are applied to porous cardboard panels, dried at standard temperature and at 40F (4.5C) with 50 % relative humidity in both cases, and their re flectances measured. A special colored penetrating medium is applied to each, the excess removed in a specified manner, and reflectances measured again. The difference between the readings on the stained and unstained films indicates the porosity of that film; the difference between the readings for the two temperatures indicates the coalescence of that film compared to others in the series.
4. Significance and Use
4.1 This test method provides no absolute information, rather ranking only of the selected series of paints.

SjjCh the reading was made. *6.4 Using the 10-mil (255-pm) blade, apply the pene-
,ting medium to each test paint, covering the area marked V above and drawing the applicator blade in the same Erection as before.
6.5 After 5 min 15 s, wash off excess penetrating Jium. To do this hold the panel vertically and remove the medium using the camel's hair brush wet with odorless
mineral spirits. Repeat the process until most of the excess is removed then apply the mineral spirits directly from the waSh bottle to the area above the stain and allow to flow rjown across the stained area. Pause to observe the bead that forms at the bottom of the panel. If the bead is not clear, continue washing with odorless mineral spirits until the bead is essentially clear. Test with filter paper to be sure no dye
remains in the bead. 6.6 Hang the panel in a vertical position and air dry for 3
h. As before, read the percent reflectance over the same area on the panels with the same flat rigid opaque object behind
them. 6.7 Place one panel for each paint, the 6-mil (150-p.m)
clearance drawdown blade, and the can of each paint into the
cold cabinet maintained at 40 2F (4.5 1C) and 50 5 % relative humidity.
6.8 At the end of 24 h remove one can of paint and stir thoroughly. Then remove the drawdown blade along with one panel and make the drawdown immediately. Repeat the process for each paint under test. All items should be kept
out of the cold cabinet only long enough to make draw downs.
^'P Place all the panels back into the cold cabinet and dry for 48 h.
6.10 Repeat the reflectance readings before and after application of the penetrating medium to these panels in accordance with 6.3, 6.4, 6.5, and 6.6.
7. Calculation
7.1 For each paint calculate the difference between the percent reflectance of the unstained and stained films at both standard and low temperatures. These two differences indi cate the porosity of the film formed at the two temperatures. Calculate the low-temperature coalescence of each paint as the ratio of the porosity at low temperature to the porosity at standard temperature which is indicative of relative coales cence.
8. Report 8.1 Report the order of low-temperature coalescence of
the test paints in the series.
9. Precision and Bias
9.1 In an interlaboratory study of this test method in which one operator in each of six laboratories tested paint films of three normally different levels of coalescence, all six laboratories ranked the three paints in the same order of coalescence. However, there were considerable differences between the values obtained by the laboratories for any one paint.

4.3 reverse roller coat--coating with the applicator or coating roll revolving in a direction opposite to that of the strip.
4.4 direct roller coat--coating with the applicator or coating roll revolving in the same direction as the strip.
5. Sampling
5.1 The number of samples per unit of production shall be agreed upon between producer and user.
6. Liquid Coatings Properties
6.1 Viscosity: 6.1.1 Coatings in the coil industry cover a wide range of generic qualities with many of them having non-Newtonian characteristics. It is therefore important to consider the behavior of these coatings under different shear conditions as well as measuring efflux viscosity by the Ford cup. 6.1.2 Determine viscosity in accordance with Test Methods D 2196 and D 1200. 6.1.3 Viscosity by Zahn cup.9 6.1.3.1 Apparatus--Standard Zahn cup with specified orifice, a No. 4 or 2 orifice is most commonly used. Stop watch. 6.1.3.2 Procedure--Clean the Zahn cup thoroughly. The sample must have a volume of at least 1 pt and the Zahn cup and sample must be 73.5 3.5F (23 2C). Thoroughly mix the sample. Dip the Zahn cup in a vertical position into the sample being tested, making certain the cup is completely immersed in the liquid but do not allow the cup to touch the bottom of the container. Rapidly lift the cup out of the sample and as the top edge of the Zahn cup breaks the surface start the stop watch. Stop the watch when the first break in the flowing stream of liquid is noted at the orifice exit. Record the seconds elapsed, temperature and number of the Zahn cup used. 6.2 Weight Solids (NVM)--Determine nonvolatile matter in accordance with Test Method D 1353. 6.3 Volume Solids--Determine volume solids in accor dance with Test Method D 2697. 6.4 Fineness of Dispersion--Determine fineness of grind in accordance with Test Method D 1210. 6.5 pH: 6.5.1 Control of pH in the pretreatment section of the coil line as well as of waterborne coatings is important in production. 6.5.2 Determine pH in accordance with Method E70.
7. Metal Pretreatment (Conversion Coating)
7.1 The successful performance of any coil-coated mate rial is dependent not only on the organic coating used but also on the metal preparation. Metal preparation in the coil coating industry usually consists of one of the following:
(*> Clean (b) Rinse
(O Formation of conversion coating
(d) Rinse
(a) Clean (*) Rinse (ri Formation of conversion coating
Drying
(e) Posttreatment of conversion coating
(/) Drying
7.1.1 The metal pretreatment promotes maximum f ability and improves adhesion and environmental expo^ resistance of the coil coating material. Cleaners, convex coating treatments and posttreatments used vary witw
performance desired, the paint and the metal. Because th6 m is an interdependency between the cleaning, couve^ coating, and posttreatment steps, in order to obtain re!ev^ test data, it is necessary that the chemicals, times, conceit? tions, temperatures, and application methods be as close3' possible to those encountered under production condition
7.2 In the case of zinc coated steel surfaces, Piactj D2092 Methods A, B, C, and D illustrate the variety 5. pretreatments available.
7.3 Coating Weight of Metal Pretreatment--In tnam, cases, one quality control measurement is the coating of the metal pretreatment formed. The following method are recommended:
7.3.1 Zinc or Iron Phosphate Conversion Coatings ,,,, Steel--Determine the weight of the iron phosphate convej. sion coating on steel in accordance with NCCA II-1 and tht weight of the phosphate conversion coating on hot dip galvanized steel in accordance with NCCA II-3.
7.3.2 Chromate-Conversion Coatings on Aluminum--]^ termine the weight of the chromate conversion coating on aluminum in accordance with NCCA II-2.
8. Panel Preparation
8.1 Summary ofMethod--This method includes substrate and pretreatment selection for application of coatings by wire wound draw-down bars10 on laboratory panels.
8.2 Choice of Substrate--The substrate to be coated, substrate size, gage, temper, alloy, pretreatment to be used shall be agreed upon between the producer and user. Avoid using treated substrates that have been contaminated by handling or cleaned with solvents or cleaners.
8.3 Degassing of Substrate--Some galvanized substrates tend to absorb gasses on aging. To avoid blistering when the substrate is coated and baked it may be necessary to degas the substrate by heating and cooling to room temperature prior to application ofthe coating. The time and temperature of the degassing cycle shall be agreed upon between the producer and user.
8.4 Drawdowns:
8.4.1 Apparatus--Wire-wound draw-down bars, stainless steel bars preferably '/z in. (12.7 mm) in diameter to prevent bowing during application. The choice of the specific draw down bar is dependent on the dry film thickness required and the volume solids of the coating being tested.
8.4.2 Procedure--Secure the substrate to be coated on a hard uniform, even surface. Place an excess amount of the coating to be used near the top of the substrate. Place the draw-down bar in the puddle of the coating to be applied. Rotate or turn the draw-down bar slightly in the coating puddle to ensure complete distribution of the coating in the

9.5.2 Impact--Determine the impact resistance of a coilcoated material in accordance with Test Method D2794.
9.5.3 Wedge Bend--Determine the wedge bend flexibility in accordance with Test Method D 3281.
9.5.4 Conical Mandrel--Determine the conical mandrel flexibility in accordance with Test Methods D 522.
9.5.5 T Bends: 9.5.5.1 Summary of Method--T bend flexibility is a means of evaluating film flexibility and correlating T bends to fabrication properties, by examining the individual T bends for fracturing and tape adhesion of the coating on each bend. The bends are classified 0T, IT, 2T, 3T, etc., with a 0T bend being defined as a 180 deg bend, (paint on the outside of the bend) pressed flat so there is no space between the metal and the bend (Note 1). The IT bend is made by wrapping or bending the metal around the first bent (OT) so that one thickness of metal is between the new wrap, this bend is pressed flat so there is no space between the metal and the bend. This process is repeated to produce the number of T bends required. (See Fig. 1.) The type of metal substrate to be used, whether or not the bends are to be made with or against the grain of the metal, the designation for identifying T bends and the temperature at which the bends will be made should be agreed upon between the producer and user.
NZ[' 1--This is the preferred identification of T bends, however,
another method is used based on the inside radius of the bend and is Vi of the preferred designation.
9.5.5.2 Apparatus--Brake form machine.11 9.5.5.3 Procedure--Place the panel to be tested into the bed of the brake face, coated side down. Bend panel 180 deg at a uniform rate and press panels flat so there is no space between the metal and the bend, this is the OT bend. Repeat this process to achieve the desired number of T bends. Examine the T bends under 10-power magnification and report the degree of fracturing on each bend based on a rating system agreed upon between the producer and user. Tape each bend with a tape12 agreed upon between the producer and user. 9.5.5.4 Report--Report the degree of pick off on each bend in a manner agreed upon between the producer and user. 9.6 Adhesion--Determine the tape adhesion of coil mate rials in accordance with Test Method D 3359. 9.7 Pressure Marking and Blocking--Determine pressure marking and blocking resistance of coil-coated materials in accordance with Test Method D 3003. 9.8 Overbake--Determine the effect of overbaking a coil coating material in accordance with Practice D 2454.

10. Exterior Durability and Accelerated Tests
10.1 Outdoor Exposure:
10.1.1 While the accelerated tests given elsewhere in this practice are intended to enable prediction of probable performance, actual outdoor exposures should be made on coatings intended for exterior use. The usage ofpaint systems in the coil area and the liability connected with these systems is so varied that no one set of conditions (length, location, and manner of exposure) can be given in this practice to cover all situations. These conditions, as well as the type of substrate, pretreatment, bake schedule, etc., should be agreed upon between the producer and the user.
10.1.2 Throughout the outdoor weathering tests, several properties should be evaluated periodically or at time inter vals agreed upon between the producer and user in accor dance with the following methods:
10.1.2.1 Blistering--Test Method D 714. 10.1.2.2 Chalking--Test Method D 659. 10.1.2.3 Checking--Test Method D 660. 10.1.2.4 Cracking--Method D 661. 10.1.2.5 Rusting--Method D 610. 10.1.2.6 Corrosion--Method D 1654. 10.2 Accelerated Durability: 10.2.1 Salt Spray Resistance--Salt spray testing of coat ings may be helpful in determining their resistance to failure in service under conditions of high humidity and salt concentrations. Under the accelerated conditions of the laboratory test, the temperature, pH, concentration of the salt solution and other physical parameters can be con trolled. The selection of substrate, pretreatment, the coating system, the manner in which the coating is scribed, the location or position of the panels within the cabinet, the length of the test, the inspection of panels and method of reporting results must be agreed upon between the producer
and user. Test for salt spray resistance in accordance with Method B 117.
10.2.2 Acidified Salt Spray--The acidified salt spray is used in the coil industry as a more accelerated test (com pared to regular salt spray) for evaluating corrosion resis tance of coatings over aluminum. Determine the acidified salt spray resistance of a coating in accordance with Method B287.
10.2.3 Humidity--Determine the humidity resistance of coil-coated material in accordance with Practice D 2247.
10.2.4 Water Immersion--Determine the resistance of a coil-coated material to water immersion in accordance with Practice D 870.
10.2.5 Accelerated Weathering--The intention of the ac celerated weathering test is to cause the degradation of coating films to occur much faster than in natural weathering in various field conditions, The apparatus produces more rapid, but not necessarily the same type of failure of films as
does natural sunlight because of its higher level and larger peaks of UV irradiation. Materials which absorb at wave lengths where the peaks in UV occur will degrade more rapidly than those that are transparent to those wavelengths. Most, but not all, organic binders are especially sensitive to
radiation below 300 nm, and in some cases, no realistic evaluation of weathering properties can be expected. For these reasons, correlation between natural and accelerated weathering is not always obtained. Whenever possible com
parisons should be made with materials having similar vehicles and known durability. Conduct accelerated 'weath ering testing on coil-coated finishes in accordance with Practices D 822 or D 3361 (Note 2), or method agreed upon between producer and user.
N\]' 2--Practice D 3361 does not use filters and the specimens areSJ
exposed to UV below 300 nm.
10.2.6 Filiform Corrosion Resistance--Filiform corrosion, ,, is a type of corrosion that occurs under single-coat systems- , on a metal substrate and is characterized by definite thread-,' like structure and directional growth. When filiform corro sion occurs on residential siding the esthetic value of thejil siding is reduced since the corrosion cannot be washed off. Determine the susceptibility of a coi! coated material to thisi. type of corrosion by Test Method D 2803.

3. Significance and Use
3.1 A number of laboratory procedures are used to evaluate the effectiveness of fire-retardant and fire-resistant treatments and coatings. In general, these methods measure the three stages of fire development: (7) ignition; (2) flame spread (rate of growth of the fire); and (3) conflagration extent While all three are of extreme importance, flame spread has been recognized as the main factor associated with testing fire-retardant coatings.
3.2 Flame spread ratings based upon Test Method E 84 have acquired common acceptance by regulatory agencies, but such large-scale tests are seldom practical during the development or modification of a fire-retardant coating.

Ncd' 4--Douglas fir, Vi-in. (6.3-mm) 3-ply, marine-grade plywood
may be used upon agreement between manufacturer and user. Asbestoscement board, steel, or concrete may be used upon agreement between manufacturer and user.
5.1.1 Prior to coating, condition test panels for 14 days in the controlled atmosphere of 50 5 % relative humidity and 73.5 3.5"F (23 2C) to a 9 to 10 % moisture content. Refer to Table 1 for the density and weight per panel ofeach listed wood.
5.1.2 Seal the ends of the panels with two coats of varnish conforming to Fed. Spec. TT-V-119 after conditioning. Allow each coat of varnish to air-dry 18 to 24 h.
6. Calibration Standards
6.1 Zero-Flame Spread-- Asbestos-cement board, Type F conforming to Specification C 220, Vr by 3% by 23% in. (13 by 100 by 605 mm), conditioned as in 5.1.1.
Nef' 5--Inorganic reinforced cement board, 'A-in. (6.3-mm) thick
may be substituted for asbestos cement.
6.2 Fire-Rated Standard--A test panel, similar to that ' used with test coatings, coated with Test Method E 84 rated
paint at the manufacturer's recommended spreading rate and conditioned as in Section 7.
Ngh' 6--Do not use paint beyond manufacturer's stated shelf life.
7. Preparation of Test Panels
7.1 Thoroughly mix the coating under test by a suitable means until it is uniform in composition and consistency. Test Method D 2196 describes a suitable preparation proce dure.
7.2 Determine the density of the coating in accordance with Test Method D 1475 in pounds per gallon (or grams per millilitre) for calculating the weight of the coating to be applied to the panel to comply with the specified spreading rate.
7.3 Brush apply the coating to conditioned test panels in as uniform a manner as possible to obtain the specified spreading rate. A suitable procedure appears in Test Method D 344. Application may be by other conventional means and in as many coats as required to obtain the necessary weight of coating or desired wet- or dry-film thickness.
7.4 Calculate the weight of coating to be applied using the following equation:

7.4.1 Use the following equation when metric units are employed:
Or
where: W = weight of applied wet coating, g, D = coating density, g/mL, and Sr = spreading rate in m2/L.
7.5 Dry the coated panels under standard conditions (4.9) until equilibrium weight is obtained, allowing sufficient time for the complete evaporation of solvents, any curing that might be required by the material, and for the attainment of equilibrium moisture content. Forty-eight hours are nor mally sufficient except for certain coatings that may require longer periods because they trap solvent or contain solvents that evaporate very slowly.
7.6 Apply and cure non-air-drying coatings as recom mended by the supplier and condition as specified in 7.5.
8. Calibration of the Tunnel
8.1 Calibrate the tunnel prior to each day's operation with the calibration standards described in Section 6.
8.1.1 Place the zero flame-spread standard in the holder, smooth side down, and back it with the backing plate (4.5).
8.1.2 Open the gas valve and adjust to a pressure of 3 oz/in.2 (1.3 kPa) and a constant flow of 4.8 ft3/h (38 mL/s), and actuate the interval timer.
Nij' 7--These conditions are specified for a natural gas supply
providing 1055 BTU/fP (40 MJ/m1). For any other gas supply, adjust flow to provide 5085 BTU/h (1490 J/s).
8.1.2.1 When the timer sounds, ignite the burner using the ignition transformer. Observe the flame front, measure in inches and record at 15-s intervals the flame position by aligning the notches in the bottom of the specimen holder with the markings on the observation window.
8.1.3 Record the extreme tip ofthe flame advance (flame front) on the panel surface, disregarding flame extending up the tunnel but completely on the angle iron support. After a total test period of 4 min, extinguish the burner.
8.1.4 Calculate the mean of the three highest consecutive readings of the flame advance of the zero-flame spread standard La.
8.2 Repeat the calibration procedure using a fire-rated standard (6.2). Designate the mean of the three highest consecutive readings of the flame advanced as Ln. The difference between the mean readings for the zero flamespread standard and the fire-rated standard (LK - La) is directly related to the Test Method E 84 flame-spread rating of the rated standard {FsR).9
9. Procedure for Determination of Flame-Spread Rating
9.1 Remove a test panel (Section 7) from the controlled atmosphere, weigh immediately, and then mount in the specimen holder, coated-side down. Insert the thermocouple through the hole in the holder (4.6) so that its tip is directly above the center of the burner and resting on the back, or uncoated side, of the test panel. Back the panel with the asbestos-cement board and steel backing.
9.2 Apply the flame and determine the advance of the
flame front in the same manner as the calibration procedure (Section 8), Except allow the burner to operate for an additional 60 s after making the last of the 15-s readings before extinguishing the burner. Designate the mean of the three highest Consecutive readings of the flame advance of the specimen during the 4-min test period as Ls.
9.3 Repeat the determination with at least five panels.
10. Calculation
10.1 Calculate the experimental flame-spread rating using the following equation:
where:
(t. Er

standard, in. (mm), and Fs r = flame-spread rating of rated standard.
10.2 Calculate the mean ofthe replicate panels, roundinu off to the nearest five units.
11. Optional Measurements
11.1 Afterfiaming Time--Observe and record the time in seconds that flaming continues on the face of the test specimen after the burner has been extinguished. Report as afterfiaming time.
11.2 Afterglow Time--Observe in subdued light and record the additional time in seconds that the surface of the1 test specimen continues to emit light (glows) after the flame has gone opt. Report as afterglow time.
11.3 Patiel Consumption--After the completion of the flame-spread test (Section 9), replace the specimen in the' constant aftmosphere. (see 5.1.1) for not less than 72 h Reweigh the panel and determine the weight loss in grama Report loss as panel consumption.
11.4 Degree of Intumescence--Measure the height of intumescence (foam formation) in millimetres at the point on the specimen that was directly above the burner. Report the heightias intumescence.
11.5 Insulation Value--Measure the initial panel temper ature in djegrees Celsius or Fahrenheit and subtract it frem the maxiniium temperature observed during the flame-spread test (Sectipn 9). Report the difference as AT.
11.6 Char Dimensions and Index--Cut the panel inf four rectangular pieces using a fine-toothed saw so that 1i.' cuts intersect at the point of flame impingement (directly over the burner). Measure in centimetres the maximum width of (fharring of the wood found below the paint film uu the lateral cut. Likewise, measure the maximum length of charring found on the longitudinal cut. Measure the max imum depth to which charring has penetrated as evidenced ' on either cut. Determine the char index by multiplying the1 maximum char width, length, and depth.

operator error are the chief sources of error in operation of the 2-foot (610-mm) tunnel.
13.1.2 The degree of repeatability is dependent on the level of flame-spread ratings. Table 2 shows that while the standard deviation of duplicate results increases with an increase in ratings, the coefficient of variation decreases by a factor of more than 2.0.
13.1.3 The standard deviation in Table 2 relates to the maximum difference that would be expected between dupli cate panels; that is, a second result in the flame-spread range from 0 to 25 should fell within 4.8 units (2.8 x 1.2) at the 95 % confidence level
13.2 Bias--The procedure in this test method for mea suring flame spread has no bias because the value of flame spread can be defined only in terms of a test method.

p4. Significance and Use
4 I Samples are taken from batches, lots, and shipments Isfccf p unt in order to determine their uniformity and compli'lj&4iKC with specification requirement?. It is very important " jffhat these samples be of convenient and economical size and
^ffitthey be representative of the batch ofpaint at the time it gg| filled into shipping or storage containers. B,2 The time and effort necessary to ensure that the title is representative of the original material will be
Jpfid in reduction of laboratory work and elimination of
wjsible rejections of acceptable material.
| Sampling Considerations
19.1 The use of common sense and good judgment is Pjnportant even in the apparently simple task of taking pimples.
This practice is under the jurisdiction of ASTM Committee D-1 on Paint and plated Coatings and Materials and is the direct responsibility of Subcommittee
1.20 on Quality Assurance and Statistics.
i Current edition approved Sept. 15, 1991. Published November 1991. Origi-
ijjly published as D 3925 - 80. Last previous edition D 3925 - 81 (1985)C1. P Annual Book ofASTM Standards, Vol 06.01.
5.2 Use care to assure that all containers, agitating equip ment, and sampling apparatus are clean and that they can in no way contaminate the sample being taken. Slight contam ination of the paint sample may lead to false test results.
5.3 The sample container should be dry and not cooler than the temperature ofthe area in which the sample is to be taken.
5.4 Because pigmented coatings are dispersions and not solutions, finely divided pigment particles dispersed in the coating vehicle may settle upon standing. Consequently, thorough and careful agitation before sampling is necessary to restore the paint to its original, uniform condition. The method of agitating or stirring is therefore of prime impor tance.
5.5 As soon as samples of paint are taken from the shipping or storage container, place them in clean, nonreactive, dry, air-tight containers to prevent evaporation. Do not store samples in plastic bottles because volatile solvents may diffuse through the walls. Loss of volatile solvents may introduce errors in such tests as viscosity, weight per gallon, and nonvolatile content as well as other properties. If cap liners are used, they should also be nonreactive with the material. If the sample is self reactive or
highly volatile, appropriate sample container precautions should be taken to prevent over-pressurization of the con tainer.
5.6 When representative samples have been obtained and packaged in clean, closed containers, deliver them promptly to the testing laboratory. During the period between sam pling and delivery to the testing laboratory it is important that samples be kept at temperatures from 40 to 100"F (5 to 40Q because extremes of temperature may change proper ties of some paint products.
6. Procedure 6.1 Because of differences in physical properties, some
what different procedures are required for agitating and sampling those paints containing water as the volatile component in comparison to those containing organic sol vents. For coatings with no volatile ingredients, use the method'applicable to materials containing organic solvents.
6.2 Pigmented Coatings Containing Organic Solvents-- Materials in this group are of many different types but all contain organic solvents, not water, as their volatile portion and they are fluids, not dry powders.
6.2.1 Small Containers: 6.2.1.1 When the batch to be sampled is filled in small containers and batch numbers are marked on the container, put all containers from the same batch together. From each batch select at random 1 % of, but not more than five containers, using the next larger whole number if a fraction
595
DU P050297776
D 3925
results. For example, if there are 275 containers in a batch, select three for test.
6.2.1.2 After selection of the filled, unopened containers, thoroughly agitate or stir the contents by the best means available. Acceptable methods of mixing are mechanical shaking or stirring or hand stirring with a paddle, followed by "boxing," that is pouring back and forth between the original and a clean empty container. Mechanical shakers are desir able for most materials since there is thorough agitation in a closed container. To prevent evaporation, agitate in a closed container lacquers and other coatings containing a highly volatile solvent.
6.2.1.3 Before mechanical shaking, open the container and check to be sure that the pigment has not caked on the bottom of the container. If this condition exists, stir manu ally to break up the hard settling and then put the containers on the mechanical shaker. Agitate paints having a weight per gallon of 11 lb (1.3 g/mL) or less on the shaker for 10 min and those with a weight per gallon of more than 11 lb for 20 min.
6.2.1.4 Once the contents have been thoroughly agitated, pour half of the material into an empty container and take a 1 qt (1 L) (or smaller iftaken from a container of 1 qt or less) sample from each half. Determine the weight per gallon on each sample in accordance with Test Method D 1475. The two determinations should not differ more than 0.5 %. If the results differ by more than this the paint is not thoroughly mixed. Return the material to the original container, stir again, and repeat the test.
6.2.2 Containers Larger than 5 Gal: 6.2.2.1 30 and 55-Gal Drums--From each batch select at random 5 % of but not more than three containers. Drums may be stirred satisfactorily by several; means. With openhead types, mechanical or manual stirring may be used. Some drums contain their own agitators; drum shakers or rollers may also be used. After thorough agitation, take samples from the top and bottom of the drum and compare weights per gallon as described in 6.2.1.4. 6.2.2.2 250 to 500-Gal Containers (Tote Tonics)--Select
at random 25 % of all containers for test. Take samples from top and bottom of the container and compare weight pcr gallon determinations as described in 6.2.1.4.
6.2.2.3 Tank Wagons and Tank Caw--Sample each com partment of the wagon or car. Pigmented paints and coatings packaged in large containers are generally formulated to be essentially nonsettling. Therefore, take samples from the top, middle, and bottom of the container and make weightper-gallon determinations before any vigorous stirring is done. If the resulting tests fall within the limits describe! earlier, no further agitation is necessary. Samples may bi obtained with a Bacon-bomb sampler or a "thief" apparatus
6.3 Pigmented Coatings Containing Water: 6.3.1 Handle pigmented coatings containing water (latex paints, etc.) in a slightly different manner from solventthinned coatings. Water-thinned paints, if stirred too vigor ously, have a tendency to incorporate air bubbles, whiol sometimes result in changing the physical properties of thi paint. 6.3.2 With the above consideration, take the samples in accordance with the same general procedure outlined in 6.2 for paints containing organic soLvents. If it has been neces sary to shake, stir, or agitate a water-thinned paint vigor ously, deaerate the samples before the weight-per-gallon test! are run. 6.4 Samplingfrom Tanks at the Factory--Mix the mate rial in the tank thoroughly before completely filling two 1-qi (1-L) containers. If the containers are to be filled from? valve on the bottom or side of the tank, mix the material draw off at least 5 gal (20 L) through the valve and ret '-ri ti the tank before taking the sample. 6.5 Sampling During Filling of Containers at the Fac tory-kites the material is thoroughly mixed in the ta 1 filling ofcontainers has commenced, take a I-qt (1-L) sample when about 25 gal (100 L) have been filled and another wh ,i . about 25 gal remain to be filled.

3. Products
3.1 It is recommended that standard commercial products offered to the general public for a period of 2 years or produced and sold in accordance with applicable govern ment specifications be considered for purchase by the methods described in Sections 4, 5, or 6.
4. Active Ingredients/Cost Ratio Method
4.1 This method utilizes, as an indication of quality, the coating composition provided by the manufacturer and is limited to interior and exterior wall paints listed in Annex A2.2.
4.2 Only those ingredients considered to contribute di rectly to quality are considered. The major active ingredients in most paints arc vehicle solids/ or binder and primary hiding pigments.
4.2.1 The weight percent of vehicle solids may help to predict the scrubbability or cleanability of a paint, but the quantity of pigment must also be considered. In general, the greater the ratio of vehicle solids to pigment, the better the scrubbability and cleanability will be. The ratio of vehicle solids volume to pigment volume is a more useful parameter

but is not readily available. Moreover, each type of vehicle solids, such as alkyd in solvent-borne paints and vinyl or acrylic latex in waterborne paints, has its own properties and there are many other additives not shown that can affect scrubbability, cleanability, and other properties.
4.2.2 The amount of primary hiding pigment, for ex ample, titanium dioxide in a white or pastel gloss finish, is an indication of hiding power. Paints of equal depth of color (light reflectance) should be compared, since lightness affects visual hiding.
4.3 An advantage of the method is that no special equipment or experience is required. Even if extensive testing is possible, the active ingredients/cost ratio method is valuable for initial screening. The active ingredients/cost ratio for several types of paint can be combined into a single figure for each supplier with each paint's "Use Factor." (see Section 7 and Annex A5).
4.4 The active ingredients/cost ratio method is not as conclusive for flat paints that often have a high "Use Factor." The hiding (opacity) of flat paints, particularly latex paints, cannot be predicted from the amount of hiding pigments since these paints often obtain much of their hiding from air in a porous paint film (conventional dry hiding) or air incorporated in the components of the film (micro-void techniques). Consequently, performance tests should be made on latex flat paints whenever possible. The cost per gallon of those latex flat paints with acceptable performance can be used in conjunction with the active ingredients/cost ratio for this type of paint.
4.5 Calculation ofIngredients/Cost Ratio--Use the proce dure in Annex A1 to calculate the ratio of active ingredients to unit cost of the paint. The greater the ratio, the more active ingredients a paint has per unit cost. In general, this will help determine if a paint is a good buy for the money, but may not determine the quality of a paint.
Nst' 2--A lower quality paint at o lower cost may tie a good buy,
but may not be of the desired quality.
5. Performance/Cost Ratio Method
5.1 Paint can be tested using standard test methods such as those suggested in Annex A2. Although there are many other test methods used in paint formulating and manufac ture, the methods listed have been found to be most useful to the consumer in determining the quality of a product.
5.2 Since different products have different properties, specific test methods have been suggested for each type of product shown in Annex A2. The purchaser may eliminate some of these tests, if the property that the test measures is not important to him, or may add other tests.
5.3 Paint testing by the purchaser requires purchase oftest equipment and some skill in performing and interpreting test results. However, a few basic tests such as hiding (opacity), porosity, or scrubbability can be tun with relatively inexpen sive equipment and will help considerably in determining the quality of a paint.
5.4 The quality of a paint can be determined by analysis of test results. Some results are descriptive, such as "good" or "poor" while others are numerical but with large numbers from some test methods, such as 450 for scrubbability, or small numbers from others, such as 0.990 in measuring hiding. Also with some tests the higher the numerical values,
the better the quality, but with others lower values indicate better quality. For these reasons the original results from the different tests cannot be directly combined into an equation to provide a numerical ranking.
5.5 If the purchaser wants a numerical value for overall
quality to use in ranking various products, it is suggested that a scale from 0 to 10 be used for all test methods. Descriptive words can be converted to a numerical rating scale such as:
Excellent Very good Good Fair Poor Very poor
Many ASTM test methods already use the 0 to 10 scale, but numerical results can be converted to this scale as shown in '
Annex A3.
No t e 3--ASTM does not intend to define quality for the purchaser, The scales shown in Annex A3 are given as examples that can be,! modified by the purchaser, if desired.
5.6 Many of the important properties of a paint that ca|
be tested and evaluated by a professional painter are listed it) J
Annex A2. The purchaser can request that the painter note |
unusual behavior during the application ofthe coating; *=i'ch .< judgemental rating of properties not normally tested cat. be 1
used as an aid in the paint selection process.
5.7 Calculation ofPerformance/Cost Ratio:
5.7.1 Use the procedure in Annex A4 to calculate tb$3
performance/cost ratio from the results obtained from lab#F
ratory tests or those supplied by painters, or both.
?
5.7.2 The calculated ratio will indicate if a paint has high, j performance relative to cost. It is possible to have a highJj relative ratio even though the overall quality may be low irf the paint is low in cost. The overall quality of producM should, therefore, enter into cost comparisons to ensure thaw they provide the quality desired by the purchaser. It is aljffijj
possible to have a high overall quality rating for a paint an(nl
still have some property that is not acceptable to
purchaser. It is therefore suggested that minimum stin v
,!
be established by the purchaser for those proper i;
considers important. 5.8 Information Provided by the Supplier--If the pur-'f|
chaser is not equipped to perform tests, he can request fijgf manufacturer to supply test results that can be used fiffij
performance/cost evaluations. Ifthe purchaser is equipped to, run some simple tests or ifa professional painter is availaliif
for evaluation, he need ask the manufacturer to supply da*1
only for those properties requiring considerable skill ::
expensive equipment to measure.
6.Specification Method
6.1 Specifications can provide a useful, mutually satisiacH tory mechanism for listing essential quality requirements ofa|
product. A specification is a document that attempts ter* describe precisely the requirements that a product must meet;
to be considered suitable for a particular use. Requireme it^ may be based on composition of the product or its perfor mance. Composition requirements are easier to iftoitiw*-. while performance requirements, which are preferred, ate; more difficult to establish and evaluate. Consequently, most
coating specifications are a combination of both types.
598
DUP050297779
D 3927
iS Specifications establish the minimum level for a duct, but if requirements are set too low it becomes limit to purchase superior coatings that may be a better fe. Specifications may encourage manufacturers to for||fe special products that meet the specification but are ent from those sold to the general public.
J3 State and local government purchasers may write a fefication for each product, but considerable knowledge
uJpaint properties and how they are related to practical ' g^iilicat'on and performance of the product is required.
X'^jCveirment purchasers may use Federal specifications ali? i ready prepared for many products.
! ,`tV. &:pUse Factor
? A use factor can be determined by dividing the total
!
annual cost or quantity of each type of paint by the total cost or quantity of all paints used by the purchaser. These factors permit each type of paint to influence the evaluation of bids in direct proportion to the quantity used.
7.2 If a purchaser wishes to consider the purchase of a complete line of paint from one supplier, then all of the ingredient/cost or performance/cost ratios for each of the supplier's products can be averaged to give an overall value for each supplier's line of products. Since different products in a line may vary in quality, more emphasis should be given to those that the purchaser intends to use the most. This can be done by multiplying the ratio for each paint by the use factor as shown in Annex A5 to determine the weighted average.

! 1 This test method covers the determination of the ' &.;mty of gloss or sheen of a paint applied by brush to a
panel simulating an interior wall section. Variations in ujpg or sheen that may be caused by short wet edge time,
g|r leveling, and pigment orientation or flotation during Bafter application are evaluated visually, Jjf.2 Because both the application and the panel evaluation m-very subjective, this test method should be used only for Hparative testing within one laboratory as the ratings fggned by different laboratories do not usually agree (see
jUii MIBbS This standard may involve hazardous materials, oper-
and equipment This standard does not purport to fjMg-ess all ofthe safety problems associated with its use. It is \fflkresponsibility of the user of this standard to establish
Jmdpriate safety and health practices and determine the Wmicability Ofregulatory limitations prior to use.
Kshimmarv of Test Method
K. 1 Paint is brush applied to a test panel using procedures ^conditions that are most likely to cause nonuniformity if gloss or sheen. The dry film is then viewed under
>n<litions that accentuate variations in gloss or sheen and - --me overall appearance is evaluated.
p{:Significance and Use
J*3.1 When coatings are applied to large flat surfaces such
ue. as walls, the film thickness may vary or there may be small ~ ivs missed entirely (holidays) when the color of the fresh
J pttbrial and the previous film are very similar. It is much Ss costly if these areas can be touched up instead of having ;iJKo repaint the entire surface. 1.2 Thickness is also affected in the locations where an >t;.ncu coated a short time before is joined with the area jiSYui rently being coated (laps). An application technique that may affect the final appearance of the film is brushing or Polling the material in different directions in adjacent areas, Wfc 3.3 Both buyers and sellers are interested in determining ffjl'.vhether a coating can be applied without exhibiting areas j*.:h;it differ in appearance because of laps and brush or roller 1 Ifmarks, and whether it can be readily touched up to provide a r jpiniform appearance in regard to gloss or sheen and all other
^aspc cts.

4. Apparatus
4.1 Paint Brush,1 2 in. (50 mm) wide with polyester bristles 2% in. (70 mm) long, chisel tip Vis in. (10 mm) thick. Previously used brushes are preferred.
4.2 Paint Brush* 1 in. (25 mm) wide with polyester bristles 2`A in. (57 mm) long, chisel tip Vie in. (15 mm) thick. Previously used brushes are preferred.
5. Reagents and Materials
5.1 Laminated Fiber Board,4 524 by 12 in. (610 by 300 mm) with at least one smooth side.
5.2 Latex-Base Primer* 5.3 Control Paint (optional)--Since there are no standard panels, photographs, or paints for this test method, an agreed-upon paint of known uniformity of appearance should be included with the test paints as a control, unless the paints are only ranked.
6. Procedure
6.1 Apply the latex primer by spray to the entire face of a smooth side of the test panel so as to coat it uniformly at a spreading rale of about 450 ft2/3gal (11 m2/L).
6.2 Air dry at least 18 h under standard conditions of 73.5 3.5F (23 2C) and 50 .5 % relative humidity and examine tlje panel for uniformity of primer application. If this appears satisfactory, divide.the coated area into sections A and B as shown in Fig. 1.
6.3 Mount the panel vertically and position it as shown in Fig. I'with section A to the right and section B to the left of the operator. Before painting, wet the brush with water if latex paints are to be tested or VM & P naphtha if the test paints are solvent reducible and shake out as much liquid as possible before using. Apply the paint under test to section A with the 2-in. (50-mm) brush (Note) at a spreading rate of 450 25 ft2/gal (11 0.5 m2/L). About 13 g are required to cover this area but theexact amount can be determined from the following equation:
g = [Mx BO/S] x 3.15
where: A - area, in.2, W. = weight per gallon, lb/gal, and S = spreading rate, ft2/gal,
2 A polyester brush No. B-20CS from The Lencta Co., Ho-Ho-Kus, NJ, has been found suitable for this purpose.
3 A polyester brush No. B-10 from The Leneta Co. has been found suitable for this purpose.
4 Upson board, available from General Distributing Co., Lockport, NY, or The Lcncla Co., has been found suitable for this purpose.

or the following metric equation:
g = [(Am x D)/SJ x 1000
where: Am = area, m2, D = density, g/mL or kg/L, arid

Make the initial brush strokes in the direction of the length of the panel and finishing strokes acrdss :the width of the panel with the wet edge feathered. Corriplete the painting of this section in about 45 s.
Nuv' --This test method can be modified for roller application by
using a small 3-in. (75-mm) roller instead of the 2-in. (50-mm) brush to rank the uniformity ofaseries ofpaints when applied by roller. The 1-in. (25-mm) brush should still be used for touch up.
6.4 One minute after completing the painting of section A, apply paint to section B with the same brush still wet with the test paint. Use the same amount of paint and time to coat section B as .for section A but make initial brush strokes across the width of the panel and finishing strokes along the length of the panel. Brush the finishing strokes into section A overlapping this section by about 2 in. (50 mm) (see Fig. 1, area C).
6.5 Thirty seconds after completing the painting of sec tion B, use the still-wet brush but without additional test material to cross brush a figure X on this section as shown in Fig. 1, area D. Air dry for at least 18 h under standard conditions.
6.6 Using the 1-in. (25-mm) brush and the spreading rate as in 6.2, apply the test paint to an area of about 3 by 5 in. (75 by 125 mm) of section A (Fig. 1, area E). This is to simulate a wall section that has been touched up after the previous coat has dried. Allow the completed test panel to dry a minimum of 18 h under standard conditions.
6.7 View low gloss finishes at a 5 angle to the plane oftbe' panel (85 to the normal) looking toward a strong light source. View gloss or semigloss coatings at 30 to the par,;! (60to the normal). Rotate the panel 360in the same plane while viewing in order to determine the overall appearance of the panel as viewed from different sides. Rate the test panel for gloss or sheen uniformity between sections using the following scale:
Rating
Score
Excellent Very good Good Fair Poor Very poor
A rating of excellent means that there is no discernible variation in .gloss or sheen between different areas of the panel. A rating of very poor means that there is a great s| variation in gloss or sheen between different areas.
,6.7.1 Variations in gloss or sheen may be caused by' various paint and substrate properties and application tech niques so that lapped, cross-brushed, and touched up anus will not necessarily have the same degree of sheen or gloss uniformity and it may be advantageous to rate each of these11 areas separately.
7. Interpretation of Results
7.1 The uniformity in appearance of a wall can be estimated by evaluating the variation in gloss or sheen between areas A and C of the test panel.
7.2 The uniformity in appearance ofa paint that has been applied by brush in different directions can be estimated by evaluating the variation in gloss or sheen between areas B and D.
7.3 The uniformity in appearance oftouched-up areas can

Precision .1 In an interlaboratory study of this test method in ih one operator in each of six laboratories tested three nts of different levels of uniformity of appearance, all six
laboratories ranked the three paints in the same order of appearance but there were considerable differences between the actual ratings assigned by the laboratories to any one paint. The test method should, therefore, be used only for the comparative evaluation of a test paint against a mutually agreed upon control paint or for ranking a series of test paints.

This standard is issued under the fixed designation D 3960; the number immediately following the designation indicates the year of original adoption Dr, in. the case ofrevision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This practice provides measures of the volatile organic compound (VOC) content of solventbome and waterborne paints and related coatings as determined from the.quantity of material released from a sample under specified bake conditions.
Nwx' 1--Other terms used as synonyms for volatile organic com
pound are photochemically reactive organic compound (PROC) and volatile organic substance (VOS).
1.2 This practice provides a guide to the selection of appropriate ASTM test methods for the determination of VOC content.
1.3 Certain organic compounds that may be released under the specified bake conditions are not classified as VOC as they do not participate in atmospheric photochemical reactions. Such nonphotochemically reactive compounds are referred to as exempt solvents in this practice.
1.4 VOC content is calculated as a function of (7) the volume of coating less water and exempt solvents, and (2) the volume of coating solids.

W.Cvolatae fraction, and requires/allows water determination for fA'ictfsprne coatings only.
rS.lpignificance and Use
A! Bp This practice discusses applicable ASTM test methods
Win the determination of the VOC content of paints and Kd coatings and provides equations for calculating the
f content expressed as the mass'of VOC in: (I) pet unit j||B.h of coating less water and exempt solvents, and (2)

Ihc amount of VOC released from different coatings Jgjfffoi the same application; that is, to coat the same area
fee same dry film thickness (assuming the same appliea-
'ypffidency). VOC content data are required by various regulatory
cfcies`. PpP Only the expression of VOC content as a function of

y zS J<< ' 4--Thus, a coating with VOC content of 3 lb of VOC/gal less
Iff and exempt solvents would release about 85 % less VOC than a ling with 6 lb of VOC/gal of solids;
Nonvolatile and Volatile Content
jp Guide D 2832 includes suggested time/temperatuie ring schedules for the determination of the nonvolatile ! volatile content of various types of coatings.
$P{' 5--For regulatory compliance testing, follow the method and
niitions specified in the applicable regulation. Federal Reference le'jibd 24 specifies the use of Test Method D 2369.
.? Test Method D2369 includes a specific drying
lipriule and sample weight, and heating. 1 h at 110 5C for "lelgrmination of the weight percent volatile;content of ijventborneawdwaterboxree.coatings. .. 6.2.1 For multicomponent coatings, Test Method D 2369 'Pacifies the components should be mixed fust, then ffie
Virile content,should be determined bn the mixture. Test sptc'mens are held in the aluminum dish for at least 1 h before baking.
|}N ' 6--U.S. EPA will allow the test specimens to stand at room
temperature for up to 24 h prior to baking at 110 5C for 1 h.
7. Water Content
7.1 To determine the water content" of waterborne coat ings two test methods are available:
7.1.1 In Test Method D 3792, a paint specimen is diluted with dimethyl formamide, an internal standard (2-propanol) is added, and an aliquot of the mixture is injected directly into a gas chromatograph;
7.1.2 In Test Method D 4017, a paint specimen is diluted with pyridine and a catalyst (1-ethylpiperidine) is added to obtain a rapid and definitive titration end point.
7.1.3 With waterborne multicomponent coatings, the components are first mixed in the appropriate ratios, then water content is determined using Test Methods D 3792 or D4017.
8. Density
8.1 The density of the paint or coating at 25C is
determined in accordance with Test Method D 1475. Al
though, both the pycnometer and weight-per-gallon cup are
covered by the test method, and the former is more accurate
and precise, the weight-per-gallon cup is recommended
because of its speed and ease of use.
,
8.2 With multicomponent coatings, first mix the compo
nents in appropriate ratios in sufficient quantity to deter
mine the weight-per-gallon using Test Method D 1475.
9. Exempt Solvents
"9.1 In Test Method D4457 ah internal standard (1propanoi) is added: to the tbst specimen, and then the specimen is injected directly into a gas chromatograph.
9.1.2 With multicomponent coatings, the exempt solvent content is determined on the mixture of the components.
10. Calculation of VOC Content
10.1 In this practice VOC content is expressed in two ways: {/) as the mass of VOC per unit volume of the coating less water and exempt solvents, and (2) as the mass of VOC per unit volume of coating solids. The following equations should be used to calculate VOC content and may be used for coatings both "as supplied" and "as applied" (see Note 7).
~N ' 7--For compliance with VOC regulations, the VOC content
should he calculated after any thinning or dilution ("as applied"), instructions for VOC calculations of such diluted coatings are available in EPA 450/3-84-019.

XI. AUTOMOTIVE COATINGS SUPPLIERS ROUND ROBIN
XL I A round robin was conducted at the laboratories of automotive coatings suppliers for determination of VOC using Practice D 3960. The analysts involved were persons experienced in running all the test methods involved in,VOC determination. The data was analyzed statistically in accor dance with Practice E 180. As was suspected from previous round robins conducted to evaluate Practice D 3960 (which involved some laboratories not familiar with these test methods), when well experienced analysts conduct the tests, the precision data is much improved.
X1.2 The interlaboratory study involved four laboratories and six samples; four solvent-reducible automotive topcoats and two water-reducible automotive topcoats. One operalo. in each of the four laboratories analyzed the sample in duplicate on 2 different days. The following duplicates, repeatability, and reproducibility coefficients of variation were obtained.

X2. CALCULATION OF VOC CONTENT (SECTION 10)
jjj 2.1 Measurement of Exempt Solvent Content--The
5 of the weight percent or volume percent of exempt jgnt in the VOC expression (Eqs l, 3, and 5) can be Untied using Test Methods D4457 and D 1475 if the
ent is methylene chloride or 1,1,1-trichloroethane. 2.2 Two or More Exempt Solvents--For solvent or |l:-reducible coatings containing more than one exempt wnt, the values for Ex and (Ex){DJDCK) to be used in Eq
' <'0.2.1, 10.2.2.2, 10.2.2.4 or 10.2.3.2} are the ^S&inmations of the values of Ex and (Ex)(DJD^'d for each
jlidual solvent. Also, the value for Ex to be used in 10.3.1 determine V0 in Eq 5) is the summation of the individual
plues. .3 Volume Nonvolatile Content--The volume percent Volatile content, K,,, in Eq 5 (10.3.1) can be calculated the summation of the individual contributions of each .ponent in the coating formulation ("p" components) | the following equation (Notes X2.1 and X2.2):
% = 2 [([ fnJiX Vyf 100)]
(X2.1)
% -- volume percent of nonvolatile component "j," [(100 %) x (volume of nonvolatiles of "j" per unit volume of "j")], and
- volume percent of component "j'' in the coating [(100 %) x (volume of "j" used)/(total volume of coating)].
X2.1--Instructions for calculating the value for the formula at volume solids (or formula volume percent nonvolatile) content lb" c rating are provided in Practice D 5201.
N' X2.2--Eq X2.1 is meant to clarify the equation (H-4) currently
in the EPA certification manual EPA-45Q/3 84-019 for the expression of calculated volume percent nonvolatile content,
X2.4 Amount of VOC in a Coaling Expressed in Terms of
Mass of VOC per Unit Volume of Coating Including Water and Exempt Solvents--The amount of volatile organic compounds in both solvent- and waterborne coatings can be expressed in terms ofthe mass of volatile organic compounds per unit volume of coating including water and exempt solvents according to the following equation (Note X2.3)
VOA = 100
(X2.2)
where: VOA = Amount of volatile organic compounds in g/L of
coating including water and exempt solvents.
N' X2.3--Calculation of the amount of volatile organic com
pound based on the total volume of coating (including water and exempt solvents), as illustrated in Eq X2.2, does not provide a measure ofthe amount ofVOC that would be released from two coatings used for
the same application (that is, to coat the same area to the same dry film thickness assuming the same application efficiency for each coating)
when one or both ofthe coatings contain water or exempt solvents. These units do not identify which of the coatings will release the greater amount of VOC as they treat water and exempt solvents as coating solids. These units, therefore, have not been used, recommended or
accepted by U.S. EPA for demonstration of compliance with VOC content regulations as such calculations yield misleading results for coatings that contain water or exempt solvents.
N' X2.4--The expression in X2.2 is useful for the calculation of
the mass of VOC released per unit of time (for example, the mass of VOC per unit of volume including water and exempt solvents times the volume of total coating used per unit of time).

INTRODUCTION
In making appearance measurements, it is important that the specimens selected be representa tive of the material of interest. Once selected, the specimens must be carefully examined to determine if they are suitable for measurement, and if not, they must be cleaned or otherwise prepared. Careful attention to these factors & necessary if the measurements are to be valid.
Scope |1, This practice provides a guide to selection of specifli.for appearance measurement as well as a discussion of ps to be considered in their preparation for measure|L Standardized selection and presentation procedures (assist in achieving agreement between evaluations carjjjnit in different laboratories as well as helping to achieve correlations between visual evaluations and instrufial measurements.

meats. For this reason instrumental readings are affected importantly by, the manner in which specimens are selected and presented for measurement. Reproducible measure ments are facilitated by standardization and control of test conditions.
S. General Requirements
5.1 Specimen Size--The minimum size is dictated by the size of the specimen port of the instrument to be used for measurement. When an instrument provides a choice of specimen port sizes, use the largest port that can be com pletely covered by the specimen. A large measured area helps to minimize the effect of any small area nonuniformity and is therefore more likely to provide results that agree with the involuntary averaging that takes place when specimens are observed visually. A large specimen also permits the operator to make measurements,, on several areas of-the specimen when desired thereby providing further specimen averaging.
5.2 Opacity-*-An opaque specimen shall be selected whenever possible for gloss and color evaluation. When the specimen is translucent or transparent, the following points should be considered:
5.2.1 For Gloss Evaluation--The specimen shall be suffi ciently thick that a secondary reflection from the back or second surface of the specimen cannot enter the receptor optics of the glossmeter. When thin transparent specimens must be measured, adopt one of the following procedures:
5.2.1.1 Back the specimen with a light absorbing material of the same refractive index as the specimen, and in optical contact with it.
5.2.1.2 Use an agreed upon specimen thickness, including coating and. substrate and place a black backing behind the specimen.
5.2.2 For Color Evaluation--The choice of backing of even slightly translucent specimens will affect their measure ment. Use the most applicable of the backing techniques that follow. In each case it is essential that the backing material and color be reproducible, stable, and durable for reliable results.
5.2.2.1 Back the specimen with the same material with which it will be backed in its intended use.
611
DUP050297792
# D 3964
5.2.22 Back the specimen with identical or similar mate rial.
5.2.23 Back the specimen with a neutral material whose luminous reflectance is essentially the same as that of the specimen being evaluated.
5.2.2A Back the specimen with a black surface such as a painted panel or black glass.
5.2.2.5 Back the specimen with a white backing of known reflectance.
6. Physical Properties
6.1 The specimen shall be rigid and have a plane surface. Specimens of thin, flexible material that can bulge or sag when presented to an instrument require special holding equipment When the specimen is moderately flexible, a plane surface may be achieved by pressing the specimen against the instrument with a flat, rigid object. The pressing technique must be reproducible. A vacuum plate or specially designed clamping device has proven satisfactory in some applications. Note that specimens coated on thin plastic film or paper may trap air between the specimen and the holder (vacuum plate or clamping device) causing the specimen to billow (blister) resulting in erroneous readings,
6.2 Surface Texture--Some coatings have pronounced surface texture, making it desirable to rotate a specimen in its own plane. Those with marked directionality, usually due to the production process, will have different values when measured in different directions. Good practice dictates that measurements be made with the plane of measurement of the instrument both parallel to as well as perpendicular to the process direction.
7. Cleaning of Specimens
7.1 The specimen must be clean. There should be no dirt, dust, oil or foreign material on the surface that will affect the
instrumental evaluation of the specimen. If the specimen appears to require cleaning, the procedure should be agreed upon and it should be carried out with care. Any cleaning of a low-gloss or fragile surface may scratch or polish the surface and thus change the appearance of the specimen and render it useless for measurement. A high-gloss specimen <n usually be washed with clear water and blotted with untreated lens tissue or paper towel. If the specimen is durable, a mild nonfluorescent, nonionic detergent that doss not leave a film can be used with a soft cloth or bristle brush. If the specimen is durable and has an oily or stubborn contamination that should be removed, reagent grace isopropyl alcohol may be used. Follow ail cleaning tech niques with a warm water rinse and drying by blotting, usun; untreated lint-free paper towel. '
N' 2--Ceramic or porcelain enameled instrument calibration
standards require periodic cleaning and the above procedures caa generally be used safely.
8. Handling Specimens
8.1 Handle specimens by their edges. Do not allow objects to contact the front surface of the specimen. When placing the specimen on the instrument, avoid sliding it across it. specimen port.
9. Report
9.1 When the specimens submitted for appearance measurements depart from the ideal requirements, report the following:
9.1.1 Their condition (Section 6), 9.1.2 Method of cleaning (Section 7), 9.1.3 Method of backing (5.2.1, 5.2.2, and 6.1), and 9.1.4 Indicate direction of specimen submitted for mea surement or averaging of data, or both, when required by directionality (6.2).

3.7.2 median--the central observation in an ordered set
that contains an odd number of observations or the mean of the two central observations in an ordered set with an even number of observations. The median is not distorted by extreme values so that where the observations are not symmetrically distributed it is a more representative average than the mean.
3.8 expected value--the mean of an infinite series of independent determinations on the same item obtained by the same procedure; also thought of as the true value that would be obtained if all extraneous variations were elimi nated. In practice, it can be closely approached by a finite series of tests, the number of tests needed being dependent on the extent of variation (scatter) of the observed values.
3.9 accepted reference value--a value that serves as an agreed-upon reference for measured values. It is derived as a theoretical value based on scientific principles or an assigned
value based on experimental work by (a) competent national or international organization(s).
N' --When the accepted reference value is the theoretical value, it
is sometimes referred to as the "true" value.
3.10 accuracy--the degree of agreement of individual or mean measurements with the expected or accepted reference value.
3.11 error--the deviation of a measured value or group of measured values from the expected value or accepted refer ence value.
3.11.1 random error--the chance variation that occurs in all experimental measurements despite the closest possible control of all factors. It is characterized by the fortuitous occurrence of both positive and negative deviations from the mean or the expected value. The algebraic mean of the
deviations'is zero in a large series of measurements. 3.11.2 bias--a systematic as opposed to, a random, error
that contributes to the difference between the estimated mean of the population and the accepted reference or the true value.
3.12 dispersion--the variability (scatter) of the observed values, usually measured about some central value such as the mean.
3.13 range--the difference between the lowest and highest values in a set of observations or results. The range is a simple but useful indicator of the variability of test results.
3.14 outlier--an extreme value far enough from other results in a series to be suspected of not belonging to the particular population under consideration. Statistical criteria are available for judging whether a given outlier should be included in the analysis of results or discarded (see Section 13). Also called "wild," "rogue," "maverick."
3.15 variance--a measure of the dispersion of a series of results around their mean. The variance of the parent population is estimated by summing the squares of the individual deviations from the mean and dividing by one less than the number Of results.
D< ( <o n--Since the variance of a set of results and the estimated'variance of the parent population are not equal because of different divisors (n for the set, n -- 1 for the population), the same symbol should not be used for both.
3.16 standard deviation--a measure of the dispersion of a series of results around their mean, defined as the positive square root of the variance.
D< ( < n--The advantages of the standard deviation are that it is in the same units as the original results and is of the same order of magnitude as the deviations from the mean. The standard deviation is thg basis for most state ments of precision and may be obtained from an analysis of variance of results of an interlaboratory test program.
3.16.1 pooled value--the weighted mean obtained by combining in accordance with statistical rules two or more separate values shown to be members of the same (homoge neous) population. Variances, if shown to be homogeneous by appropriate statistical criteria, may be combined by weighting each variance in accordance with its degrees of freedom, summing them and dividing by the sum of the degrees of freedom. Standard deviations must not be arith
metically averaged; they must be squared to convert them to variances, combined, and the square root taken to obtain the pooled value.
3.16.2 coefficient of variation--a measure of relative pre
cision calculated as the ratio of the standard deviation to the . mean of a series of values, expressed in percent.
3.17 degrees offreedom--in a set or subset of observa tions, the number of values minus the number ofconstraints. In general, there is only one constraint--the number of; values. For example, a set of n observations can be arranged into g groups. The group degrees of freedom is then g - i because n'is already determined. Similarly the total df is n -- I (see Table 8).
-3.18 probability--the chance of occurrence of an event expressed in terms of a relative frequency, a fraction, or a
percent. For example,' the probability that a tossed coin will land head up is one in two, or 0.5, or 50 %.
3.19 confidence limits--the limits on either side of the1 mean value of a group of observations that will, in a stated fraction or percent of the cases, include the expected value. Thus the 95 % confidence limits are the values between which the population mean will be situated in 95 out of 100 cases.
3.20 confidence level--the probability level (usually with reference to a statistical table) with which the significance of differences between measurements is assessed. Thus, a differ ence that is significant at the 95 % level (0.05 probability level, sometimes called significance level) would represent a real difference 95 times in 100; however, 5 times in 100 a difference this large might arise by chance even with identical.)! material because of experimental error.
3.21 significant difference--a difference between two.) values, means, or variances that is shown by tests of. significance to be a real difference at the stated level of : confidence.
3.21.1 Student's l test---a statistical test for assessing the
significance of a deviation from the mean or of the difference between two means. The /-value is based on the ratio of the observed deviation, or difference, to the standard deviation and is compared with tabulated /-values that indicate the frequency with which a difference of this magnitude should occur by chance in samples having the appropriate degrees of freedom.
3.21.2 variance ratio (V) test--a statistical test for as sessing the significance of the difference between two or more variances. The F test (named in honor of R. A. Fisher) is based on the ratio of the larger variance to the smaller

12.1.2 Correlation--If a test procedure is being evaluated for its ability to provide results that correlate with the known property values of materials, a correlation coefficient is computed and tested for significance.
12.1.3 Precision--The precision of a test procedure is determined by computing intralaboratory and interlabora tory variances from the test results obtained for each material. If the variances for the materials are homogeneous, they are pooled and an overall intralaboratory standard deviation and an overall interlaboratory standard deviation are calculated and used in the precision calculations. If the variances are inhomogeneous, means of providing homoge neity (such as use of the coefficient of variation or other transformations of the results) are given.
12.1.4 Sensitivity--A sensitivity criterion (figure of merit) is computed and used as a measure of the ability of a test procedure to distinguish between materials differing in the property being measured.
13. Test for Outliers
13.1 An outlying observation, or outlier, is one that appears to deviate markedly from other members of the set
in which it occurs. This outlier may be a single valui', mean, or a range.
13.2 When the experimenter is clearly aware that a gi deviation from prescribed experimental procedure has taken place, the resultant observation should be discarded, whell a it agrees or not with the rest of the results. If a relia correction procedure is available the observation may c corrected and retained.
13.3 In many cases, evidence for deviation from the., prescribed procedure consists of the discordant value itsci' In such cases a statistical test is applied to determine if the**1: 3 doubtful value should be discarded. A simple technique for, [
this purpose is the rejection quotient procedure. It consists of U) ranking the values (single observations, means, or ranges),.1 in order of their magnitude; (2) taking the difference betw.een the extreme value and the nearest value to it, and (3) dividing that difference by the appropriate range of urn values. The resulting quotient, Q, is compared with the established rejection quotient (RQ) for the number of items in the series of values. If Q exceeds the RQ, the extreme value is suspect and may be discarded. Table 1 gives the equationKrfj for computing Q and the RQ values for three significances! levels as a function of the number of items in the test results.

To reject one of the eight differences, Q must exceed 0.544 at id 0.10 significance level (90 % confidence level), 0.608 at
EHfe 0.05 significance level (95 % confidence level), and 0.717 liie 0.01 significance level (99 % confidence level). Since a
significance level of 0.01 should be used for iiitralaboratory (lest results, it is concluded that the difference of 0.7 is not fejectable and must be included in the calculation of test .precision.
14. Correlation
14.1 To be useful, a test method must provide values for materials that either relate directly to the known property or component values for these materials or that relate to the values from another test method that is related to the known values. The degree of association between the values of a test method under study and the values ofa standard test method can be determined by computing the correlation coefficient.
14.1.1 The correlation coefficient, r, may be defined by the equation:
2(X-X)(Y- Y) ` [2(X.-X)22(Y- Tfp'
2XY-_ (2X2Y/n)
where: X = value obtained for a material by standard test method, Y = corresponding value obtained for a material by new _ lest method, X -- mean value obtained for a material by standard test _ method, Y = mean value ^'obtained for a material by new test
method, and n -- number of values obtained with each test method.
14.1.2 The reliability of the correlation coefficient de pends on the number of materials tested as well' as the degree of linear relation between the two test methods. It should be pointed out that a calculated r value represents the relation of the two test methods only over the range of values obtained. Thus, if the material? selected for evaluating a test method differ only slightly in their property or component levels, the calculated rmay not correspond to the correlation that would be obtained if materials differing widely in these values had been tested.
14.1.3 The correlation coefficient, r, is dimensionless and its values range from 1.0, perfect direct relation, to -1.0, which indicates perfect inverse relation. An r of 0 shows no relation between the two test methods. Whether a value of r between 0 and I is significantly different from 0 can be determined from Table 2 that gives the critical values at several probability levels as a function of the degrees of freedom, n -- 2, where n is the number of materials tested.
14.1.4 The correlation coefficient squared, r2, (called the coefficient of determination) provides additional informa tion about the degree of correlation between the two test methods. It is a useful concept in the sense that r2 is equal to the fraction of the variation ofthe dependent variable Y that may be ascribed to the effect of the independent variable X. To claim good correlation exists between two test methods, a value ofat least 0.9 for r is required, since r2 = 0.81 indicates only 81 % of the variation in Y can be ascribed to X. If a
value of 0.7 or less is obtained for r, the degree of association is considered to he inadequate for assuming that the two procedures are measuring the same property. It should be pointed out that a high value for r does not guarantee that values of Y can be predicted precisely from vaiues of X.
14.1.5 An example of the computation of the correlation coefficient to determine the degree of association between values of two test procedures is shown in Table 3. Tills single laboratory test consisted of measuring the drying time of 10

14.2 There may be instances where no actual instru mental values are available for the materials tested, only their relative ranking being known. In these cases, a rank correla tion coefficient, rj, can be computed to express the degree of relationship between the ranking of the X values of one test method and the Y values of the other test method.
14.2.1 In computing r/, the results from the two proce dures are each arranged in order of performance and each material assigned a rank. In the cases where two or more materials have the same rank, each is assigned the value corresponding to the mean of the ranks that would be assigned to them if the rankings were sequential. By taking the differences, RD, between the two sets of rankings for liie materials, rj is calculated from Spearman's equation a, follows:
r; = 1 - imRDfhin'1 - 1)] = 1 - m(RD?Hn3 - )]
where: n = number of materials and RD = difference between the rankings of a material. A test to determine if r/ is significantly different from 0 can be made conveniently with Table 4 in which S(RD)2 values at two probability levels are given as a function of the number of pairs.
14.2.2 An example ofthe procedure for computing a ra 1 correlation coefficient is shown in Table 5. In this example, the performance of 10 products subjected to two test procedures is represented by a relative ranking of thuperformance. It is seen from the significance table of S(RD)2 as a function of number of pairs that the value off 1 obtained: in this example is highly significant (99 %) since S(RD)2 u less than 39 for the probability level of 0.01. It is concluded that the degree of association between the two test procer' dures is good.
15. Precision
15.1 The precision of a test method is expressed in two
terms, repeatability and reproducibility. Paragraphs 15.1.1 and 15.1.2 provide the complete mathematical formulas calculating precision, but a shortened procedure for analysis^ of results from a balanced design is given in 15.1.3. Whcit `, values have been discarded as a result of application'of tl-, test for outliers in 13.1, the mean of all the values for the-;;Ji respective determination can be used to replace them. retain a balanced design. It should be recognized that the analysis used in this practice is abridged because interactionsbetween factors are disregarded. Consequently, some infor mation that could be obtained from a complete analysis .s sacrificed, as in Practice E 180.
15.1.1 Repeatability (Intraboratory)--Test repeatability i' determined from the estimated intralaboratory variances computed from the repeat determinations made within each laboratory on each material.
15.1.1.1 For this practice, the equation defining the esti mated variance, xw2, (Note 3) within a single laboratory is as follows:

15.1.1.6 Compute the maximum allowable difference (MAD) by multiplying sw by the q factor (Table 6) for the appropriate number of replicates in each laboratory and the degrees of freedom (nm materials) x (nL laboratories) x (time -- 1). In case test results are missing, compute the nL (/ - 1) degrees of freedom for each material and total them.
15.1.1.7 Examine the results from each laboratory for each material to establish whether all results are within the MAD for intralaboratory determinations. If this range is exceeded and outliers were not previously rejected in accord ance with 13.3, discard the discordant results and recalculate the variance, standard deviation, and MAD. Compare with the original values to establish whether the rejection is justified; for example, a marked reduction in MAD with the elimination of only one set of results is evidence that they differ significantly from the other results and their retention would adversely affect the precision of the test method.
15.1.1.8 If the intralaboratory variances for the materials do not appear homogeneous but appear to be dependent on the level of the mean value of the materials, homogeneity may be achieved generally by converting the standard deviations to coefficients of variation:
IV = 100 sJX
15.1.1.9 If the coefficients of variation are homogeneous, pool them in accordance with the equation, as follows:
_ f(H| - 1) Vi2 + (m - 1) V22 + + (m - l)vro2lw Vp [ (,-l) + (2-l)+- -+(nm-l) J
where: v, = coefficient of variation for Material 1, and i = number of values used to establish vb etc.
When n, = n2 = nm, this condenses to (Svj2/m)%
where: ZVj2 = sum of squared coefficients, and nm = total number of materials. Calculate the maximum allowable difference in percent relative by multiplying the coefficient of variation by q for the number of repeats and degrees of freedom.
15.1.1.10 If the coefficients of variation do not appear to be homogeneous, a transformation ofthe test results (such as to logarithms, arc sine, or square root) may provide homo geneous variances.
15.1.1. II If homogeneous variances or coefficients of variation cannot be obtained from the intralaboratory re sults, calculate the precision for appropriate levels of the materia] value.
15.1.2 Reproducibility (Interlaboratory)--Test reproduc ibility is determined from the estimated interlaboratory variance which is the variance of the mean values obtained by the laboratories (sL2) plus the intralaboratory variance. Thus, interlaboratory variance is as follows:
i'b2 = (sw2/s) +
where nK -- number of repeats in each laboratory.
N' 4--The subscript, b, derives from the previously used tem,
"between-laboratories".
15.1.2.1 The equation defining rw2 and the procedures for its computation are discussed in 15.1.1.1 and 15.1.1.2.

Calculate the interlaboratory variance using the equation given in 15.1.2.
15.1.2.4 Pool the interlaboratory variances for all mate rials (unless they appear nonhomogeneous) to give a single interlaboratory variance for the test. Calculate the interiaboratoiy standard deviation, yb, and report.

interlaboratory (between) variances.6 In the analysis, it tinst be ascertained that the intralaboratory variances and
nnsvalues are consistent among the laboratories. Interlabjj|y values are not necessarily consistent, depending oiq the precision of the test method(s). Lack of consistency
arise from a variety of causes, such as materials or jigpient. As noted in 3.3, the individual replicates are }Jjfcnly for determining gross errors in test results. *8J .3.2 Following is an example of the application of the
ysis of variance to interlaboratory test results. In this |d robin, one laboratory coated, baked, and distributed Jlanels to five co-operators. Each co-operator received e panels and was asked to determine the Knoop hardness thfde different times within a given period to eliminate jnlti effects. The results submitted are given in Table 7. p5.ll .3.3 The, first step (whether using the analysis of Bounce or nqt) is to examine each replicate value for |ible errors. This is most easily done by calculating the e in results for each time and comparing the ranges at jlar levels in results. In the example given.here, in which , range appears to increase with increasing hardness, the gfits for each enamel must be compared separately, but in cs where the values for all materials are at about the same IM.1 all results must be considered together. The calculated Ages in the example are presented at the bottom ofTable 7.
15.1.3.4 Next, apply the test for outliers, 13.3, or the
control chart technique (D3) of Practice E 180, to see if a
suspect value can be rejected. When more than two replica
tions are made at a time and only one result is divergent, that
result can be discarded and the mean calculated from the
remaining values, thus retaining the balanced design of the
interlaboratory study. When only duplicate determinations
are made it is usually necessary to reject both results. In the
example, Replicate b of Laboratory V on Enamel A at Time
3 has caused the range to be larger than acceptable, possibly
the result of inverting figures when taking the readings or
preparing the report. The mean for Time 3 is therefore
calculated from the two remaining values which changes the
subtotal for Laboratory V to 3.9, the total and mean of
Enamel A to 18.7 and 1.247, arid the Laboratory V total to
140.2.
15.1.3.5 The ranges between the mean results at different
times and the laboratory means (or totals) are also examined
for discordant results to see if any should be discarded before
conducting the analysis ofvariance. In the example none are
rejectable; although the mean (and total) for Enamel E
obtained by Laboratory IV appears suspect, the calculated
quotient does not exceed the R.Q. of 0.710 for a significance
level of 0.05 and five values, as shown:
48.9 - 34.4 48.9 - 26.7
> 0.653
15.1.3.6 An analysis of variance is performed on the
jp A Basic software program to analyze test results in accordance with this results obtained for each material by the test procedure, that

is, a total of six analyses. It is necessary to compute first the variances for each material because the variances may differ
significantly for different types of materials or for different
623

laboratory variance for all materials. Obtain the intra laboratory standard deviation, jw, by taking the square root of the variance and report.
15.1.1.6 Compute the maximum allowable difference (MAD) by multiplying sw by the q factor (Table 6) for the appropriate number of replicates in each laboratory and the degrees of freedom (nm materials) x (nL laboratories) x (time -1). In case test results are missing, compute the nL (r - 1) degrees of freedom for each material and total them.
15.1.1.7 Examine the results from each laboratory for each material to establish whether all results are within the MAD for intralaboratory determinations. If this range is exceeded and outliers were not previously rejected in accord ance with 13.3, discard the discordant results and recalculate the variance, standard deviation, and MAD. Compare with the original values to establish whether the rejection is justified; for example, a marked reduction in MAD with the elimination of only one set of results is evidence that they differ significantly from the other results and their, retention would adversely affect the precision of the test method.
15.1.1.8 If the intralaboratory variances for the materials do nol appear homogeneous but appear to be dependent on the level of the mean value of the materials, homogeneity may be achieved generally by converting the standard deviations to coefficients of variation:
vw = 100 sJX
15.1.1.9 If the coefficients of variation are homogeneous, pool them in accordance with the equation, as follows:
= [(" ~ *) + ("2 ~ 1) V;2 + ' + frtm ~ Dv'm2]'^ P l (, - l) + (*2 - 1) + + (m - 1) J
where: Vj = coefficient of variation for Material 1, and
= number of values used to establish v,, etc.
When rtl = n2 = nm, this condenses to (Xv2/nm)lA
where: Xv2 = sum of squared coefficients, and nm - total number of materials. Calculate the maximum allowable difference in percent relative by multiplying the coefficient of variation by q for the number of repeats and degrees of freedom.
15.1.1.10 If the coefficients of variation do not appear to be homogeneous, a transformation ofthe test results (such as .Jo logarithms, arc sine, or square root) may provide homo geneous variances.
15.1.1.11 If homogeneous variances or coefficients of variation cannot be obtained from the intralaboratory re sults, calculate the precision for appropriate levels of the material value.
15.1.2 Reproducibility (Interlaboratory)--Test reproduc ibility is determined from the estimated interlaboratory variance which is the variance of the mean values obtained by the laboratories (sL2) plus the intralaboratory variance. Thus, interlaboratory variance is as follows:
rb2 = (Jw2/) +
where nR = number of repeats in each laboratory.
N' 4--The subscript, b, derives from the previously used tennf
"between-laboratories".
'
15.1.2.1 The equation defining s,,2 and the procedures fori
its computation are discussed in 15.K1.1 and 15.1.1.2.
15.1.2.2 The equation defining the variance of laboratory 1
means, sL2, is as follows:
1
sL2 = Z(X-XfnnL 0
where: X
X
nL (X -- X)2 nL -- 1
= mean obtained for a material by a labora- J tory,
-- grand mean of the values obtained for a | material by all laboratories,
= number of laboratories, = sum of squares, ss, and = degrees of freedom, df.
To facilitate calculations, the equation is converted to
,, 9 S-?2 ~ WXfM
15.1.2.3 When the results obtained in the interlaboratoiy test are from a balanced design and there are no missing i values, compute the sum of squares and variance for each material by the analysis of variance technique, described jn! 15.1.3. Calculate the interlaboratory variance using the * equation given in 15.1.2.
15.1.2.4 Pool the interlaboratory variances for all mater',
rials (unless they appear nonhomogeneous) to give a single J interlaboratory variance for the test. Calculate the interlabo- ratory standard deviation, sb, and report.
15.1.2.5 Compute the maximum allowable difference by multiplying rb by the q factor (Table 6) for the appropriate 1 number of laboratories and the degrees of freedom of (L - i 1) times the number of materials.
15.1.2.6 Examine the results from all laboratories to.J establish that the range of laboratory means does not exc^e j the MAD. If the range is exceeded and laboratory outliers^ were not previously rejected, discard the discordant resullsi and recalculate the MAD as in 15.1.1.7.
15.1.2.7 If the interlaboratory variances for the materials |
do not appear to be homogeneous, but appear to vary with# the level of the means of the materials, convert the standard,!
deviations to coefficients of variation, and if homogeneous.*! pool them as shown in 15.1.1.8 and 15.1.1.9. Calculate the|
MAD in percent by multiplying the coefficient of varial o by q for the number of laboratories and degrees of freedom,"
15.1.2.8 If the coefficients of variation do not appea`f'1 homogeneous, a transformation of the test results (such as to f logarithms, arc sine, or square root) may provide homogeCa neous variances. If neither variances nor coefficients ofij variation are homogeneous for the interlaboratory resulK calculate the reproducibility for each level of test value of the,, materials as in 15.1,1,11
15.1.3 Analysis of Variance ofBalanced Results: 15.1.3.1 Where adesign recommended in Part B has been used and balanced results are available (that is, uo missmg values from a balanced design or missing values replaced by the appropriate mean value), the analysis of variance tech-:;

where, if SR is greater than 1.0, Test Method A is superior to B, and if SR is less than 1.0, Test Method B is superior.
16.5 Obviously, a sensitivity ratio should not be used to compare test methods unless it has been established that one of these test methods provides instrumental values that correlate well with known property or component values of materials. For example, if Test Method A has been found to give instrumental values (observed or transformed) that correlate reasonably well (r > 0.7) with known property values, then a plot can be made of Test Method B values versus Test Method A values for the materials tested.
16.5.1 If the plot of points shows a curvilinear relation ship, then the values for Test Method B should be trans formed to provide a linear relationship. When this has been
done, the slope of the straight line relating the points is AA/AB and
SR - slope/(sA/ss)
16.5.2 In some instances, the SR for two test methods will not be constant over the range of materials tested because of
changes in the test errors with a change in parameter level. In such cases, an SR should be calculated for each '61 ih,
parameter value levels. A plot of SR values versus paramefef > values is useful in comparing the sensitivities of the two test methods.

|Procedures for Preparing Summaries
3.1 For each material or each test method, prepare, a
IpThat compiles in an orderly block arrangement the
fits from all of the laboratories (including operators and
B). A format based on the one given in Fig. 1, but modi-
J|tb include means and ranges, can be used. Using the
fen shown in Table 12, prepare,a table for each test
||||<l.giving the'laboratory mean values.and ranges for the
ggleht materials. Prepare a table, for each test method
jjg for each material the means, the intra- and interlabo-
By standard deviations, the degrees of freedom, and, if
fpcable, the coefficients of variation. The format can be
I on parts of Table 10 or on Table 11. It should be
gfht from this tabulation whether the standard deviation
fi'with the magnitude' of this property; being measured
^consequently, whether the coefficient of variation is
Iked.
:
||2 An appropriate block of results may be compiled
Jti frequency distribution table that can be prepared in
fail different Ways as follows:
1.2.1; Tabulate the values in increasing order of magm-
pnd express the frequency with which each value occurs
. fraction or percent calculated by dividing the number of
|s the value occurs by the total number of values in a
ip, When a large number of values is being treated, they
|be divided into classes of equal, range (for example, ten
||es) and the frequency of each class calculated.
|9.2.2 Calculate the deviation of each value from the
an value of its group noting the sign and tabulate these in
Sir of magnitude. Calculate the frequency of each deviai|ks a fraction or percent of ail the values treated. When a
ge number of values is being treated, the deviations may
Iglvided into classes of equal range.
jf.2.3 Frequency distributions may be expressed in a
Emulative way by arranging the values in order of magni
tude and summing at each stage ofthis arrangement the total occurrence of all values up to and including the selected stage.
19.2.4 Graphical presentations are very useful and concise allowing rapid inspection and judgment of a collection of related results. They may be prepared from all the results from an experiment or an appropriate segment to obtain a view of the nature of the distribution. Ifit is revealed that an adequate normal distribution exists, relatively simple math ematical treatments may be applied. Frequency distributions may be presented in graphical forin, as histograms whereby values or classes covering a range of values are plotted against their frequency, or as cumulative frequency graphs prepared by plotting at each point the cumulative frequency of all the values up to that point against the value at that point. One of the best ways of displaying results is the dot diagram.9 Figure 3 shows the relation ofdry-to-touch time to the day on which a test was made and to the type of drier used, and also shows the overall distribution ofthe results. It can readily be seen that there is definitely a difference between days but none between drier types, as compared to the overall distribution.
19.3 The final summary should be a description of results from the cooperative program, expressedsin terms of repeat ability and reproducibility stated with supporting informal tipn, that is, degrees of freedom.
19.4 Prepare a draft report, with the test results and their analysis, for deposit in ASTM Headquarters files.
20. Applicability and Precision Statements for Test ' Methods
20.1 T[he major functions of the interlaboratory test of a measurement procedure are the determination of:
20.1.1 The applicability of the procedure for measuring a property of a material or groups of materials, and
20.1.2 The precision with which repeated measurements according to the test method can be expected to be made.
20.2 Applicability implies bpth the correlation of a mea surable property with an unmeasurable property of a mate rial and the sensitivity with which differing levels of that property are discriminated by the test method. Correlation may be evaluated by means of a rank order correlation coefficient. Sensitivity may be evaluated by means of the sensitivity criterion (ratio of the range in property levels of a material to the standard deviation). As applicability, or

validity, of a test method depends on the magnitude of the values of correlation and sensitivity, as well as on the number of materials used in the interlaboratory test, inclu sion of a statement of applicability is recommended as
follows:
Applicability of Test Method--Based on measurements of materials having known qualitative ratings that range from____ to ---- (good to poor, for example) the rank correlation coefficient for the test method was found to be-----------and the sensitivity criterion was found to be
20.3 Precision is useful only if the applicability function of the test method is found to be favorable. Precision is defined as the degree of agreement among repeated indepen dent measurements of the same property. Statements of precision may be given in terms of the standard deviation, but this form is not very useful. In addition, when values obtained vary directly with the property levels of the materials tested, the coefficient of variation must be used to express the general precision. Statements of precision can also be expressed in terms of the range in values within which the correct value can be expected to lie a specified percent ofthe time. The most common precision index is the range that should not be exceeded for a stated number of results at a given confidence level, assuming that the frequency distribution is normal and that a random sample was used in the interlaboratory test. Because only a sample of the total population of measurements is obtained in a test, statements of precision should indicate the number of degrees of freedom and the number of observations that were used in the interlaboratory test to obtain the indicated values.
20.3.1 As can be seen from Tables 11 and 12, the measurements made in an interlaboratory test permit a number of parameter variations. Precision indexes can be devised with respect to differences within and among labora tories, materials, operators, and repeat measurements and
with respect to the interactions among combinations of the parameters. It is evident from this discussion that to provii all of these precision indexes would make this section unnecessarily long and impair its usefulness. The decision i how many of the possible indexes are to be included in a t method is left to the discretion of those who formulate ai
use the test method. In this practice, however, the pi ecisii statement is based on the two indexes --repeatabiliu <ir reproducibility as defined in 3.26:
Precision of Test Method--In an interlaboratory study of this t( method in which____operators in_____laboratories tested _ coatings with a broad range of____ (property) levels (analyzed__ materials containing__ _), the intralaboratory standard deviatii (coefficient of variation) was found to be____ units (percent) wi --_ degrees of freedom (df) and the interlaboratory stands deviation (coefficient of variation)____ units (percent) with____ after rejecting____ results(s) from____ laboratory (ies) for one tit because the range between replicates (repeats) differed significant from all other ranges for material ____, or all results from o laboratory for material____because the mean differed sigmlici' I froth all other means. Based on these standard deviations (cod dents) the following criteria should be used forjudging, at the 95 confidence level, the acceptability of results:
Repeatability--____results, each the mean of_____ replicates applicable), obtained by the same operator should be considet<ffi{ suspect if they differ by more than____units (% relative). Reproducibility--Two results, each the mean of____ replicatst obtained by operators in different laboratories should be co-w c-iCJ - suspect if they differ by more than____units {% relative).
N' 6--Where the results obtained are in percent instead of some)
unit add "absolute" after X % in the repeatability and reprodudbiii$l
statements to distinguish from cases where use of the coefficients QWf,
variation results in percent relative precision limits.
N' 7--Users of ASTM test methods should he aware that
precision obtained from an interlaboratory study is for measunaneaSg made on the same batch of each material. Consequently, nonr.ah* batch-to-batch variability, which is governed by manufacturing qualify control, is not included in the precision values established for a tc$i| method.

Pooling the coefficients of variation in accordance me formula in 15.1.1.8 yields the following:

jjeicfore the acceptable range for Enamel E is 0.172 x = 1.94 for intralaboratory results and 0.64 x 11.26 =
lifer interlaboratory results. The actual maxima obtained h. Snamel E in the round robin are for the intralaboratory

bf all six enamels. W.3 Instead of rejecting the results from all laboratories

Rejecting one laboratory's results for one material reduced
the pooled interlaboratory coefficient of variation from 15.34 % to 11.82%, which is certainly justification for discarding those results.
A 1.5 From the pooled coefficient of variation the max imum acceptable difference, vb # is 34.4 % for two laborato ries, 46.4 % for four laboratories, and 49.5 % for five laboratories (Note A 1,1). Based on these values, the accept able range in Knoop hardness results for each enamel is given in Table Al .1 and compared with the maxima found in the study.
N' A 1.1--The MAD used for determining the acceptability of
results in the round robin must be based on the number of participating laboratories while that used in the final precision statement is for two laboratories.

3il The material is dissolved in pyridine, or another .appropriate solvent, and titrated directly with standardized Kail Fischer reagent, to an electrometric end point. The
pgjish reaction with water in pyridine is accelerated with a hcmical catalyst, 1-ethylpiperidine. *`3.2 Pyridine is used as a solvent to minimize interference .rnhiems caused by ketones. It is also used because the more "omrikm solvent, methanol, will not dissolve many common resins, and because methanol reacts with some resins to Induce water.

4 Significance and Use
1 4 l Control of water content is often important in control' "% the performance of paint and paint ingredients, and it is
Jtical in controlling volatile organic compound (VOC) ntent. A,2 Paint materials are often insoluble in common Karl 'scher solvents such as methanol. Pyridine has been found

to be a nearly universal solvent for these materials; however, the Karl Fischer reaction is too slow in that solvent at room temperature. To speed it up, 1-ethylpiperidine is added at 5 % as a buffer, or "catalyst".
5. Apparatus
5.1 Karl Fischer Apparatus, manual or automatic, encom passed by the description in Test Method E 203. Apparatus should be equipped with a 25-mL buret, Class A, or equivalent.
5.2 Syringe, 100-p.L capacity, with needle. 5.3 Syringes, 1-mL and 10-mL capacity, without needle, but equipped with caps.
6. Reagents
6.1 Purity ofReagents--Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chem ical Society, where such specifications are available.4 Other grades may be used, provided it is ascertained that the reagent & of sufficiently high purity to permit its use without lessehing the accuracy of the determination.
6.2 Purity of Water--Unless otherwise indicated, refer ences to water shall be understood to mean reagent grade water conforming to Type II of Specification D 1193!
6.3 Karl Fischer Reagent.5 6.4 Pyridine. 6.5 1-Ethylpiperidinef 6.6 Hydrochloric Acid (HC1), concentrated.
N ' I--All reagents must be fresh. Do not use reagents, that are
more than 9 months old. Karl Fischer reagent deteriorates .with age. Check expiration dates on the reagent bottle.
7. Hazards
7.1 Karl Fischer reagent contains four toxic compounds, namely iodine, sulfur dioxide, pyridine, and methanol or glycol ether. The reagent should be prepared and dispensed in a hood. Care must be exercised to avoid inhalation or skin contact, Following accidental contact or spillage, wash with large quantities of water.

the same care as Karl Fischer reagent 7.3 1-ethylpiperidine is of unknown toxicity and, there
fore, should be handled with the same care as the materials listed in 7.1 and 7.2.
8. Procedure
8.1 Standardization ofKarl Fischer Reagent: 8.1.1 Add enough fresh pyridine to cover the electrode tip,
plus 1 mL of 1-ethylpiperidine catalyst per 20 mL of pyridine. Catalyst performs best at a concentration of about 5 % of the volume present.
8.1.2 Fill the 100-pL syringe to about half full with distilled water and weigh to the nearest 0.1 mg.
8.1.3 Pretitrate the pyridine to the end point indicated by the equipment manufacturer, by adding just, enough Karl Fischer Reagent 1 (KFR) to cause the end point to hold for at
least 30 s. 8.1.3.1 The use of the catalyst greatly increases the reac
tion rate between water and Karl Fischer reagent. To obtain reliable results, increase the electrode sensitivity and reduce titration rate to a minimum. Most instruments have controls
for these functions. Consult the instructional manual for information on these controls.
8.1.4 Empty the contents of the syringe into the titrator vessel. Immediately replace the stopper of the sample port and titrate with KFR to the end point as described in 8.1.3.
8.1.5 Repeat standardization until replicate values of F agree within 1 %. Determine the mean of at least two such determinations. Carry out calculations retaining at least one extra decimal figure beyond that of the acquired data. Round off figures after final calculations.
8.1.6 Calculation: 8.1.6.1 Calculate the KFR titre F as follows:
F-J/P
(1)
where: J = water added, g, and P = KFR used, mL.
The value for F should be recorded to the four significant digits and should be the mean of at least two determinations. Typical values are in the range of 0.004000 to 0.006000 g/mL.
8.2 Analysis ofSamples With More Than 0.5 % Water. 8.2.1 The titration vessel should already contain preti trated pyridine and catalyst, as described in 8.1.1 and 8.1.3 in the standardization procedure. Best results are obtained with fresh solvent, that is, containing no previously titrated specimen in the vessel. 8.2.2 With a 1-mL or 10-mL syringe, draw the amount of material indicated in Table 1.
N' 2--Paint samples tend to settle in the syringe and give bjpj,
percent water content. Obtain a freshly stirred or mixed specimen f0r : each test run.
8.2.2.) Remove the syringe from die specimen, pull the plunger out a little further, wipe the excess material off the syringe, and place a cap on the syringe tip. Weigh the filled J syringe to the nearest 0.1 mg.
8.2.3 Remove the cap, and empty the syringe contents < into the pretitrated pyridine vessel. Pull the plunger out and . replace the cap.
8.2.4 Stir rapidly for 1 to 2 min before starting titration: I Some instruments can be set to do this automatically. If the j specimen is still not dissolved or dispersed, continue stirring ' until it is dissolved, or use a different solvent in place of pyridine in 8.2.1.
8.2.5 Titrate the specimen slowly with KFR to the end point described in 8.1.3.
8.2.6 Reweigh the emptied syringe, and calculate the specimen weight by difference.
8.2.7 Calculation: 8.2.7.1 Calculate the percent water L as follows:
I = (fxFx 100)/S
(2)'
8.3 Analysis ofMaterials With Less Than 0.5 % Water. 8.3.1 For 0.1 to 0.5%, follow procedure in 8. specimen), except substitute a 1-mL microburet for the3
25-mL buret in the Karl Fischer apparatus. 8.3.2 For less than 0.1 %, use a 1-mL microburet and J
increase specimen size as much as needed, up to 10 g. It should be possible to measure moisture levels down to 1 ppm (0.0001 %) by this approach.
N' 3--Specimens with less than 0.1 % water may require sp-'i.l
handling techniques to prevent pickup of atmospheric moisture. Tlrasf
precision of this test method 'was determined with specimens containing . higher water levels.
9. Recommendations for Good Results
9.1 Make sure electrodes are clean.
9.2 Follow manufacturer's instructions to ensure that
venting into the titration vessel is only through a dessicant^
9.3 Samples should be thoroughly mixed before taking a ,
specimen.
9.4 Paints and paint materials are often slow to dissolve .
disperse. To ensure that all of the water is extracted into i
pyridine or solvent, stir rapidly for 1 or 2 min before star
the titration.
9.5 Run the titration slowly with rapid stirring.
9.6 Throw out the first result in fresh pyridine.
9.7 Use only Aldrich's 1-ethylpiperidine.6 It has been,
found that other brands produce variable results.
''ill!
10. Maintenance
10.1 Cleanup--Clean the titration vessel by rinsing with fresh pyridine. Do not use methanol or other solvents.
10.2 Dryness--Check frequently to be sure that all drying tubes are in good condition and tightly connected. Replace dessicant when indicator color changes through half oj the ' tube.
10.3 Electrode Performance--If electrode response is slug gish or otherwise off standard, take the following steps u' turn, to correct the problem. Test the electrode with a

.1. The precision estimates are based on an interifatory study in which one operator in each of seven creht laboratories analyzed in duplicate oh two different fseven samples of water-based paints of various types dining between 25 to 75 % water. The results were
analyzed statistically in accordance with Practice E 180. The within-laboratory coefficient of variation was found to be 1.7 % relative at 98 df, and the between-laboratory coeffi cient of variation was 5.3 % relative, at 42 df. Based on these coefficients, the following criteria should be used forjudging the acceptability of results at the 95 % confidence level.
11.1.1 Repeatability--Two results, each the mean of du plicate determinations, obtained by the same operator on different days should be considered suspect if they differ by more than 4.7 % relative.
11.1.2 Reproducibility--Two results, each the mean of duplicate determinations, obtained by operators in different laboratories should be considered suspect if they differ by more than 15.0 % relative.
.11.2 Bias--Bias has not been determined for this test method.

Standard Test Method for Reflection Haze of High-Gloss Surfaces1
This standard is issued under the fixed designation D4039; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year oflast reapproval. A
superscript epsilon (*) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method describes a procedure for using two specular gloss measurements to obtain a haze index for high-gloss nonmetallic specimens (1-4).2 It is particularly useful for evaluating the haze in clear finishes on nonglossy substrates, and the haze in reflected images produced by the surfaces of opaque glossy pigmented finishes.
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

3. Terminology
3.1 Definitions: 3.1.1 specular gloss--the relative luminous reflectance factor of a specimen at the specular direction. 3.1.2 reflection haze--perceived cloudiness in an image reflected by a glossy surface. 3.2 Descriptions of Terms Specific to This Standard: 3.2.1 60* specular gloss--specular gloss measured with the 60geometry specified in Test Method D 523. 3.2.2 20 specular gloss--specular gloss measured with the 20 geometry specified in Test Method D 523. 3.2.3 haze index. H--a measure of reflection haze, where H = (Gfi0 - G> ); Ge0 is the 60 specular gloss and G2o is the 20 specular gloss.
4. Summary of Test Method
4.1 Measurements of 60 and 20 specular gloss are made on a specimen. The haze index is computed as the difference between the two measurements.
1 This lest method is under the jurisdiction of ASTM Committee D-l on Paint and Related Coatings and Materials and is the direct responsibility of Subcom mittee DO 1.26 on Optical Properties.

3 Annual Book ofASTM Standards, Vol 06.01.
4.2 This test method is applicable to nonmetallic spu-. mens having a 60 specular gloss value greater than 60 m accordance with Test Method D 523.
5. Significance and Use
5.1 Haze is produced by irregularities in the reflect m surface that affect the distribution of flux reflected around the specular angle. The procedures specified in Test Method D 523 are not designed to measure reflected-flux scatter iy characteristics of high-gloss finishes, particularly where spec imens having different surface refractive indexes are being compared. A better index of scattering can be obtained hi making two specular reflectance measurements, that is, the use of two receptor apertures of different size.
5.1.1 In this test method, values for reflection haze are obtained from two measurements of specular gloss, < re made with a large receptor aperture and the other made with a small receptor aperture. The geometric conditions have been chosen to permit the use ofglossmeters that provide specular gloss measurements (large receptor aperture) and 20 specular gloss measurements (small receptor aperture) as specified in Test Method D523.
5.2 Measured gloss values of specimens depend on the , angle of illumination, refractive index of the material, and j the geometric distribution of the reflected light. The gloss scale ofboth the 60and 20 geometries is defined as 100 for polished black glass with a refractive index of 1.567. How ever, the polished black glass standards used in this lest 1 method usually have a tower refractive index (approximately ,, 1.53). Therefore, they will have a gloss value less than ti u These gloss values will be different for 60 and 20 measure-,' ments. Ifthe refractive index is 1.53, the black gloss stand;nJ will have a 60 gloss value of approximately 94 and a 20' gloss value of approximately 89. Therefore, this haze-fred* standard will have a haze index value of 94 - 89 = 5. A`K haze-free coating (refractive index of approximately 1.53)':j will have a corresponding haze index of 5 units, the difference between its 60 and 20 gloss values. Because 20 gloss changes much more rapidly with index than 60glo.s, the reflection haze value of a specimen also depends on tbe` index of refraction of the material. To establish a correction for the effect of refractive index would require measurement of the index for each specimen, which is impractical. Comparisons of reflection haze evaluated by this test method are therefore limited to specimens of essentially the same refractive index.
6. Apparatus
6.1 Glossmeter(s) capable of measuring 60 and 20 specular gloss in accordance with the specifications given in Test Method D 523.

DUP050297816
Preparation and Selection of Test Specimens
.1 This test method does not cover preparation techues. When a test requires the preparation of specimens |n a liquid coating, specify the techniques of specimen paration. |2 Select test specimens in accordance with Practice 3964. 2.1 To determine the maximum gloss obtainable from a erial, such as a paint or a varnish, use methods in Test
ods D 823 to produce a film of uniform thickness on a 6th, planar substrate. 2.2 Use surfaces of good planarity, because surface
;e, waviness, or curvature may affect test results cantly. The directions of brush marks or similar re effects should be parallel to the plane of the axis of two beams.
Calibration and Standardization
1 Calibrate the glossmeters with primary and secondary king standards in accordance with the procedures given Lest Method D 523.
Procedure
9.1 Select an area near the center ofthe test specimen and Sermine the 60 specular gloss. ,9.2 Determine the 20 specular gloss on the same area of lie specimen.
1 Calculation
0.1 Compute the haze index, H, as follows: I " Gso " G2"
where: G60 = value of 60 specular gloss and G2o = value of 20 specular gloss.
N' I--Because of the difference in the assigned values for the
black glass standard at 20 and 60", the haze index for specimens without haze will have value of approximately 5.
11. Report
11.1 Report the following information: 11.1.1 For each specimen, the measured G60 and G20 values and the computed haze index, H. 11.1.2 Where preparation of the test specimen has been necessary, describe or otherwise identify the method of preparation. 11.1.3 Identify the glossmeter used by make and mode). 11.1.4 Identify the gloss standards used.
12. Precision
12.1 On the basis of interlaboratory studies of this proce dure in which six laboratories conducted single determina tions on eight high-gloss coatings differing in visually per ceived reflection haze, the within-laboratory. standard deviation for haze index values was found to be 0,9, and the between-laboratories standard deviation was found to be 2.5.
12.2 Based on these standard deviations, the following criteria should be used for judging the acceptability of single determinations at the 95 % confidence level.
12.2.1 Repeatability--Two results obtained by a single operator should be considered suspect if they differ by more than 2 units of haze index.
12.2.2 Reproducibility--Two results obtained by opera tors in different laboratories should be considered suspect if they differ by more than 7 units of haze index.

jf' jjjpnmary of Test Method
faK'This test method is based on measurements of the tKequired for a weighted rod to fall through an aperture mtjining the test specimen,
`ffX Fall times are corrected to a reference temperature of 'tffbr other mutually agreed-upon temperature). The test
.usfltpd specifies precise measurement of actual specimen |perature in order to detect fluctuations due to cooling by I, a e(al, heat of friction during shearing, and body heat of the Ifc.'tor. ' 3 Each specific instrument must be calibrated in order
nfltablish the fall time that is equivalent to a shear rate of
' s'1. 14 Fall times as a function of weight are extrapolated to JbQI i s_1 by means of the power law (logarithmic) relation'll'p between shear stress and shear rate.' Apparent viscosity 2500 s-1 and the degree of non-Newtonianism are imined by calculation or graphically. The calculation of Sjcal low shear parameters is also covered.
JSjgnificance and Use Mp Apparent viscosity at the relatively high shear rate of
s-1 does not completely define the rheological properill of printing inks but is useful in the practical control of gViscoSity during production and the specification accep-
le between supplier and purchaser. _ 5.2 The slope of the power law plot is the preferred |i|asure of non-Newtonianism. The yield value, which is btained by extrapolation of high-shear measurements to a hlar rate approaching zero, does not conform to the efinition of the true yield stress (see 3.1.7). The yield value Ind bther low shear parameters are also Subject to a high leglfee of variability (see the precision table in Section 16).

8.2.3 To minimize heat buildup from body temperature during a run, avoid contacting the viscometer block with bare hands. When instructions call for holding the block steady, wear a glove or place a small cloth in the palm of the hand.
8.2.4 When making fall-time measurements, work quickly and without interruption so that the entire run is completed within 5 to 10 min.
N' 1--Many modern printing inks and vehicles contain some
solvent, and volatile loss during a run can seriously bias test results
unless rigorous control ofexposure time is exercised. Volatile loss can be detected if successive drops of the rod with the same weight result in
increasingly longer fall times.
9. Preparation of Apparatus
9.1 Set the viscometer on a sturdy bench located in an area free of direct drafts, direct sunlight, and other sources of
heat. Level the viscometer by turning the adjustable feet up and down until the spirit level bubble is centered.
9.2 Pass a hand over the upper and lower photocells to assure that the timer is activated and deactivated.
9.3 Attach the clamp to the ring stand and place next to or behind the viscometer. Drape the thermistor probe over the clamp; reset the clamp so that the probe end fils close to the
viscometer block.
9.4 Clean the block and rod thoroughly with tissues
wetted with naphtha. Remove residual solvent with clean dry
tissue. Roll the clean dry rod over a flat surface to check for
straightness. If rod is bent, discard and obtain a new
rod/orifice set.
.
9.5 Examine the markings at the ends of the rod. Select
one marking as an indication of the "proper" end to be
always inserted into the aperture first.
10. Calibration
10.1 Determine instrument constants in accordance with the procedure given in Annex Al.
10.2 Optional--If a graphical method is to be used for direct conversion of test results to viscosity, prepare Master Sliding Scale Calibration Graph as in Annex A2.
10.3 Periodically check calibration as in Section A 1.2.
11. Sample Preparation
11.1.1 Transport the sample to the test area and preserve in a closed container. Skin paper should be used for oxidative drying inks.
11.1.2 Ink samples should be uniform dispersions. If pigment settling is suspected, insert a spatula in the container and gently stir. Be careful not to introduce air bubbles.
11.1.3 Prior to the run, a portion of the sample may be transferred to a slab and gently spread out in order to remove bubbles, skin, or other debris.
N' 2: Caution--Do not work the sample vigorously, this practice
causes a significant increase in sample temperature. Be sure to close the container immediately after removing the desired portion.12
12. Conditioning
12.1 The temperature of the room {cabinet or collar) should be set at 23 1C (or 2"C below the reference temperature).
N' 3--In accordance with Note 8, the allowable range f0
specimen temperature is 2aC from the reference temperature. How
ever, during the coutse of testing, heat of shearing and body heat of the
operator both contribute to continuous temperature rises in (jjjf
specimens, notwithstanding room, cabinet,,or collar conditions. Xq :
allow for inevitable temperature rises, temperature controls are set at thj
lower end of the allowable range.
'
12.2 Equilibration of test samples is not necessary. Specimen sizes are small (less than 2 mL); when spread out on if slab and applied to the viscometer, both hot and cold samples quickly reach the temperature of the metal.
12.3 If the viscometer has been idle for more than an hour, it may be necessary to bring it into equilibrium with, the conditioning temperature (23C or other specified in' 12.1). Make preparations for an exploratory run (13.2 to
13.5) using a varnish if the test specimen contains volatiles. Read specimen temperature; if too low (a possibility considering that metal serves as a heat sink), add a 1000-g weight ! the rod and make a few drops (13.7 to 13.9 but without recording time) until the specimen temperature reaches thai: of conditioning. Continue the run or, if a varnish was used, clean up.
13. Procedure for Fall-Time Runs
13.1 If required, prepare, level, and condition the instrut. ment as described in 10.12.1 and 12.3.
13.2 With the proper end of the clean rod down; hold t rod vertically over the clean aperture and gently lower until it, f rests on the swinging platform.
fiS13.3 Transfer a uniform specimen to the tip of a clean
plastic spatula. The specimen size should be sufficient to the well of the viscometer.
13.4 Hold the rod with the fingertips and carefully raise about 20 .mm. Transfer the specimen from the spatula to the1! * rod as close as possible to the bottom of the well. Rotate the rod slowly to distribute the specimen around the well, ensuring that the well is full. Allow the rod to fall to the platform.
13.5 Place the thermistor probe in the well close to not touching the rod. The probe can remain in the well throughout the run. Turn the thermistor on.
13.6 Using experience or the information in Table 1 as a, guide, select a weight load, that will produce a fall time ^fl close to 1 or 2 s as is practical.
N' 4--For comparison of non-Newtonian liquids, runs must not:!;
be made at pre-specified rod weights. Rather, weights should be adjusted! to obtain pie-specified fell times, the first ofwhich corresponds as closely;) to a shear rate of 2500 s_I as is practical.
13.7 Hold the block level and steady with one hand (seSi 8.2.3). With the other hand, carefully place the selected weights on top of the rod. If weights are slotted, evenly distribute the slots around the circumference of the rod. Make certain that the rod is vertical. (If weights tend to make the viscometer unsteady, retain the hand on the block so that the rod falls smoothly in 13.8.)
13.8 Set the timer. Release the platform and allow the rod to fall naturally. If the fall time is within the desired range (for example, 1 to 2 s for the first weight, etc.), record the added weight fVA, fall time F, and specimen temperature T on worksheet.
13.9 Remove the weights from the rod. Pull the rod up

j|, Calculation
' 7---This section covers calculations by computer or program-
&b(e calculator. The list of symbols is given in 3.3. The procedure for
uphical solution of test results is described in the Annex A2.
i 1.1 Enter into the computer the values for the instru-
uent constants, WR, F2sa0 and ^2500 and the reference
operature TK.
'
'14 2 Enter data from fall-time runs in sets of Wh,
`^plicate values of F that agree within 2 %, and the corre-
ondmg values of T.
14.3 Compute the non-Newtonianism parameter N by
limuUaneous solution of the following general equation:
log W-- B -- N log Fa
(1)
"Mien.:
W = WA + WR h.li
(2)
Fc = F + 0.1 F(T-Tr)
(3)
N' 8--Equation 3 corrects each measured fall time by 10 % per
^degree differential between the measured temperature and the reference
temperature and is applicable only within 2`C of TR. As noted in the third column of Table A1.2, specimen temperature increases progres sively during a run. For accurate results, it is important that the temperature correction be applied to the fell time corresponding to each added weight. Otherwise, significaht error will bi introduced into the slope of the power law plot.
14.4 Examine (by computer) the value of N. Any value over 1.0 is improbable for a printing ink or a vehicle and suggests error in the test measurements; check data or repeat runs. Alternatively, treat any value between 1.0 and 1.05 as
1.0.
14.5 Compute the viscosity at 2500 s~' as follows:
where:
1*2500 = ^25001*2500

14.7 Optioml- -Compute the pseudo yield value as follows:
S'0 = 2.5 (K, 5 - V25(j0)
. (8)
N' 9--Since the logarithmic nature of the power law precludes a
zero shear rate, Eq 8 was derived to approximate the Bingham yield value, which is normally determined by extrapolating the linear portion of a shear stress/shear rate plot to zero rate of shear.
14.8 Optional--Compute the shortness factor as follows:

16. Precision
16.1 An interlaboratory study of this test method was conducted in which a single operator in each of nine laboratories made one run consisting of at least four repli cated data points on four inks on two different days.

the degrees of freedom are given in Table 2. (Since the standard deviation was proportional to the test value, preci sion statements are made in terms of percent ofthe observed value.) Based on these standard deviations, the following criteria should be used forjudging the acceptability of results at the 95 % confidence level:
16.1.1 Repeatability--Two results obtained by the same operator on different days should be considered suspect il they differ by more than the maximum allowable difference indicated in Table 2.

position of F2500 (from A 1.1.7) on time scale. If below 1.0 s,
the position can be located using another sheet oflog paper as a guide. Draw a horizontal line across the entire sheet of paper and label "2500 s-1 " at the far end.
A2.1.2 Along the 3-cycle axis, mark the start of the cycles as 100, 1000, and 10000. Label the scale "Total weight, g" so as not to interfere with the line previously drawn for "2500 s'1."
A2.1.3 Using the the results from fall-time runs made with standard oils (A 1.1.6.1) and found satisfactory in accordance with A1.1.6.4, plot corrected fall time versus total weight for each oil-day combination. Using the triangle, draw the best 45 line through the points so that each plot line intercepts the line labeled "2500 s'1."
A2.1.4 From a second sheet of the same type of chart paper, cut a piece along the 3-cycle axis so that the resulting slrip contains the scale plus one or two graph divisions. Add
zeros to the scale so that the second cycle starts at 10 and the third at 100; if required for high-viscosity fluids, a fourth cycle starting at 1000 may be obtained by pasting two strips together. Label the strip "Viscosity at 25C, P." Locate the
25C viscosity of each calibrating oil on the scale and draw vertical lines to the top. If three oils were used, there should be three lines on the strip.
A2.1.5 Position the top of the strip directly beneath the 2500 s'1 line drawn on the first sheet of chart paper so that the viscosity lines on the strip match as closely as possible the intercepts at 2500 s'1. Paste securely in place. Cut off portions ofthe strip that extend beyond the edges of the chart paper. Relabel "Total weight" scale if strip hides pertinent coordinates.
A2.1.6 The chart paper containing the viscosity strip represents the "Master Sliding-Scale Calibration Graph" for
a specific instrument. Prepare an overlay containing the ,i desired identification information and paste in a suitable1 place (see example in Fig. A2.1). Make sufficient copies of, the master for normal use of the instrument. Be sure to preserve the original.

N' A2.2--The Master Sliding-Scale Calibration Graph is essen
tially similar to the Inmont-Lehman chart, which is also based on,tot* power law but presumes that a shear rate of 2500 s'1 corresponds to a" * fall time of 1.0 s in all instruments. The charts issued by viscomisteiHt
manufacturers are Cartesian {I IF versus W) and are based on Bingham..
A2.2 Graphical Solution of Viscosity: A2.2.1 Make the fall-time tun on the test sample ac cording to Section 13. Compute the corrected mean Lll times and the total weights according to A 1.1.6.2 and--Al. 1.6.3. A2.2.2 On a copy of the Master Sliding Scale Calibrator * Graph (Section A2.1), plot corrected fall time versus total, f
weight for the test material. A2.2.3 Using the 45 triangle as a guide, check whether
the best straight line through the plotted points is 45 greater to the weight axis. A line less than 45 is improbable for a printing ink or a vehicle and suggests error in the test measurements; check calculations or repeat the run.
A2.2.4 Draw the best straight line through the points, making certain that the angle is at least 45to the weight axis Extend the line so that it intersects the horizontal axis at 2500 s'1. Read viscosity as the intercept on the sliding sea Record as K2500, apparent viscosity at 2500 s'1.

Designation: D 4060 - 90
Standard Test Method for Abrasion Resistance of Organic Coatings by the Taber Abraser1
This standard is issued under the fixed designation D 4060; the number immediately following the designation indicates the year of original adoption or, in the case ofrevision, the year oflast revision. A number in parentheses indicates the year oflast reapproval. A superscript epsilon.(c) indicates an editorial change since the fast revision or reapproval.
1. Scope
1.1 This test method covers the determination of the resistance of organic coatings to abrasion produced by the Taber Abraser on coatings applied to a plane, rigid surface, such as a metal panel.
1.2 Because of the poor reproducibility of this test method, it should be restricted to testing in only one laboratory when numerical abrasion resistance values are to be used. Interlaboratory agreement is improved significantly when rankings of coatings are used in place of numerical values.
1.3 This standard does not purport to address the safety problems associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

determined at a specified number of cycles. 3.1.3 wear cycles per mil--the number of cycles of abra
sion required to wear a film through to the substrate per mil of film thickness.
4. Summary of Test Method
4.1 The organic coating is applied at uniform thickness to a plane, rigid panel and, after curing, the surface is abraded by rotating the panel under weighted abrasive wheels.
4.2 Abrasion resistance is calculated as loss in weight at a specified number of abrasion cycles, as loss in weight per cycle, or as number of cycles required to remove a unit amount of coating thickness.
5. Significance and Use
5.1 Coating on substrates can be damaged by abrasion during manufacturing and service. This test method has been useful in evaluating the abrasion resistance of attached coatings. Ratings produced by this test method have corre lated well with ratings produced by the falling abrasive values in Test Method D 968.
6. Apparatus 6.1 Taber AbraserT 6.2 Abrasive Wheels--Resilient calibrase wheels No. CS-

Ip Start the vacuum pick-up and then the turntable of jpbrader. Subject the test specimen to abrasion for the Sified number of cycles or until wear through of-the aiftig is observed. In determining the point of wear jgjtigh, stop the instrument at intervals for examination of fitest specimen.
10.5 Remove any loose abradings remaining on the test specimen by light brushing. Reweigh the test specimen.
10.6 Repeat 10.1 to 10.5 on at least one additional test specimen of the material under test. ,,
11. Calculation
11.1 Wear Index--Compute the wear index, /, of a test specimen as follows:
/ = (A - B) 1000
where: A = weight of test specimen before abrasion, mg, B = weight of test specimen after abrasion, mg, and C = number of cycles of abrasion recorded.
N' 6--In calculating wear index it may be advisable to discard the
last 200 cycles because the results may be affected by abrasion of the exposed substrate.
11.2 Weight Loss--Compute weight loss, L, of the test specimen as follows:
L=A --B
where: A = weight of test specimen before abrasion, mg, and B = weight of test specimen after abrasion, mg.
11.3 Wear Cycles Per Mil--Compute the wear cycles per mil, W, of the test specimen as follows:
W -- D/T
where: D -- number of cycles of abrasion required to wear coating
through to substrate and T = thickness of coating, mils (0.001 in.) (to one decimal
place).
N' 7--In calculating the wear cycles, it is advisable to discard the
first and last readings because the first may he affected by an uneven surface and the last by abrasion of parts of the substrate.

Standard test Method for Leveling of Paints by Draw-Down Method1
This standard is issued under the fixed designation D 4062; the number immediately following the designation indicates the year of original adoption or, in the case ofrevision, the year of last revision. A number in parentheses indicates the year of last rcapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
his test method2 covers the laboratory determination relative leveling of water and solvent-reducible archi'jttU'al paints in white and light tints by comparing the Ills produced in a draw-down film to a series of plastic iding standards. ! Unpigmented, texture, and deep-tint coatings cannot ijt`i cadily evaluated with the shadowing produced by oblique jpjjng employed in this test method. Such coatings may be
Kt by comparing them with the plastic standards at
{Jjffius angles of reflection. For this purpose ordinary room jMjhg is satisfactory. bfjjs Since other factors may influence the tendency of "Sjttd paints to sag, this test method is not intended to ijlpure sagging. Bp This standard may involve hazardous materials, operJfljps, and equipment. This standard does not purport to Bfey all ofthe safety problems associated with its use. It is wjcWfsponsibility of the user of this standard to establish

1. Scope
1.1 This practice covers the requirements for photographs and photographic equipment to be used to document coating and lining failures or defects. Photographs may also be used to establish acceptance criteria.
1.2 The practice represents only one method to provide consistent, comparable photographs. The important factors to consider when using any type of photographic equipment are also described.
2. Significance and Use
2.1 The proper documentation, through photographic methods, in standard size and color is required for accurate comparison of a wide variety ofcoating and lining failures or defects. An integral part ofthe study ofdefects and failures is the ability to compare by a standardized reproducible method present and past appearances of defect characteris tics and failure modes. The equipment should not be complicated or require any special skill to produce good definition and color.
3. Requirements for Photographs
3.1 Requirements are as follows: 3.1.1 Color slides in 2 by 2-in. (50 by 50-mm) cardboard mounts, suitable for projection in ail standard 2 by 2-in. slide projectors, 3.1.2 Prints in a minimum 3 by 3-in. (76 by 76-mm) size. Unless a larger scale is needed, the standard Vh by 3`/2-in, (89 by 89-mm) size should be used. Prints may be either color or black and white, although color usually provides the greatest information to those viewing the photographs, and 3.1.3 A scale of the area photographed.
4. Requirements for Standardized Photographic Equipment
4.1 The equipment should consist of the following:2 4.1.1 A 3 by 3-in. (76 by 76-mm) copy stand complete with compensating lense. The focal depth should be approx imately Vs in. (10 mm) above the subject plane to approxi mately `A in. (6 mm) below the subject plane. 4.1.2 An 8 by 8-in. (203 by 203-mm) copy stand complete with compensating lense. The focal depth should be approx imately l`/2 in. (38 mm) above the subject plane to approx imately 1 in. (25 mm) below the subject plane.
1 This practice is under the jurisdiction of ASTM Committee D-33 on Protective Coating and Lining Work for Power Generation Facilities and is the direct responsibility of Subcommittee D33.Q3 on Quality Systems.
Current edition approved March 26, 1982. Published May 1982. 1 The Kodak Ektagraphic EF Visualmaker satisfies the requirements of this practice.
4.1.3 A camera that will accept 12 or 20 exposures 1 'i size cartridge and have a lens system compatible with tlx copy stands in accordance with 4.1.1 and 4.1.2.
4.1.4 A flash cube or an electronic flash unit designe, specifically for use with the camera-stand assembly. Tlx electronic flash should have approximately a 40-s recovery time. The electronic flash should be battery-operated and sell contained..
4.2 Equipment other than that described above may be used for photographic documentation; but, there may be varying scales and lighting effects.
5. Precautions and Limits
5.1 The following factors are the principal variables af fecting photograph clarity over which the user has control
5.1.1 Degree ofEnlargement--Enlarging a given negative beyond a certain point yields no additional clarity to the photographs; more clarity must come from either a larger or clearer negative. Enlargement should be great enough so sufficient detail can be seen without the use of a magnifying glass.
5.1.2 Negative Size--The larger the negative, the more detail and clarity it can record. It is suggested that . minimum negative size of 26 by 26 mm be used. Negati . sizes much larger that this might be needed rarely, if ev '
5.1.3 Film Speed--"Faster" films have progressively less resolution. In general, 35-ttim ASA 200 film gives poor resolution ifenlarged much beyond 4 by 5 in. when printiu
5.1.4 Lighting--Insufficient lighting gives poor resolu tion. Lighting of the wrong color such as incandescent bulbs using daylight film, distorts colors. Bright lights or fla-b perpendicular to a glossy or shiny surface causes glare. Also, perpendicular lighting may fail to show surface irregularities. Lighting at too oblique an angle may exaggerate the irregu larities.
5.1.5 Camera Stability--A rigid support such as a copy stand or tripod will minimize camera movement.
5.1.6 Camera Optics and Quality--Professional quality cameras and equipment may be impractical due to cost, difficulty ta operate, delicacy of equipment, or the need for an immediate print. Acceptable photographs can be obtained with some of the simpler, good-quality cameras.
6. Documentation
6.1 Each photograph shall be identified with the following information:
6.1.1 Date and time of photograph, 6.1.2 Where the photograph was taken and what it i* intended to show, and 6.1.3 Name of the photographer.

3.3 Constituent coats of an overall thickness of a coatmg system can be measured individually by this method.
4. Apparatus
4.1 The measurement shall be performed by first incising a scribe mark of known configuration through the coating(s) film to substrate and then viewing the scribe mark with an illuminated microscope with measuring reticle. Scribe cutter'
and illuminated microscope may be combined as a single instrument (see Fig. I).3 Instrument calibration shall be performed by taking measurements on applied filtm i-f known thickness. (See Test Methods D 1005.)
4.2 The configuration of the tungsten carbide cutting tips shall be designed to provide a very smooth incision in the paint film at a precise angle to the surface (see Fig. 2). Separate tip designs (angles) shall provide cuts of known slopes such as 1 to 1, 1 to 2, and 1 to 10. These tips shall bn nominally designated lx, 2x, and lOx to indicate the r.ii-.j of the lateral measurement (microscope) to film thickness-' (cut depth in film). Metal guide studs on the gage body shall, together with the cutting tip, form a firm base to assure that the tip aligns vertically with the painted surface for precisely aligned incision.
4.3 The illuminated, 50-power microscope shall contain alj reticle scaled from 0 to 100 divisions (see Fig. 3). The total1!*2 viewing field of the microscope shall be approximately IT" mils (3.18 mm).
5. Test Specimens

3. Summary of Practice
3.1 Several procedures that will provide accelerated rates for the degradation ofcoatings are descri&ed. The procedures appear in the following order:
3.1.1 Procedure A--Exposure on a black box panel rack facing the equator at 5 from horizontal.
3.1.2 Procedure B--Exposure on a heated black box panel rack facing the equator at 5" from horizontal.
3.1.3 Procedure C--Exposure on a Fresnel reflector panel rack that provides a high intensity of sunlight irradiation by following the sun and focusing the sunlight on the test panels ,t>y means of mirrors. The panels are wet periodically by deionized water spray.5
3.2 Each of these procedures requires that coated test panels be placed on racks of specified design and be exposed under specified conditions of weathering.
3.3 The selection of a procedure for producing accelerated degradation is. dependent on the intended end use of the coatings, limitations on the time available for the exposure tests, and the degree of reliability required for predictions of durability performance.
4. Significance and Use
4.1 The procedures described in this practice are designed to provide greater degradation rates of coatings than those provided by fixed angle outdoor exposure racks that opti mize the annual incident solar radiation. For many products, fixed-angle exposures accelerate the normal end-use rate.
, 4.2 Following are comments regarding the relative rates of degradation that can be expected for coatings exposed by the procedures described in this practice.
4.2.1 Procedure A (Black Box)--For many coatings, this procedure provides greater rates of degradation than those provided by 5, equator-facing, open-rack exposures because the black box produces higher panel temperatures during irradiation by the sun and longer time of wetness. The black box panel temperatures are comparable to those encountered

on the hoods, roofs, and deck lids of automobiles parked in direct sunlight.
4.2.2 Procedure B (Heated Black Box)--This procedure is most useful for exposures conducted in the late fall, winter, and early spring when it produces significantly higher panel
temperatures than those produced by the 5", equator facing, black box. Therefore, thisprocedure produces greater rates of degradation than those produced by Procedure A, particu larly in the case of coatings with rates of degradation that are very temperature dependent.
N' 2--The relative rates of gloss loss and color change produced
in some automotive and coil coatings by exposures in accordance with
Procedures A and B are given in ASTM Special Technical Publication
781.6
4.2.3 Procedure C (Fresnel Reflector Rack)--This method
provides greater rates of degradation of coatings than those
provided by Procedure A or Procedure B. This high acceler
ation is produced by very high sunlight intensity and high
panel temperature.
4.2.4 THe degradation rates produced by any of the three
procedures depend on the seasons of exposure, geographical
location, and type of coating. The rates are higher in late
spring, summer, and early fall when the intensity of sunlight
irradiation is the greatest and when panel temperatures are
higher. Also, the rates are highest for exposures in warm,
humid environments.
''
4.2.5 Because outdoor weather conditions vary from
season to season and year to year, these procedures are not
reliable for establishing absolute performance ratings for
coatings. The procedures should be used only for comparing
the relative performance of coatings exposed at the same
time at the same location.
5. Test Specimens
5.1 Each test specimen and control specimen shall, consist of a uniform coating applied to the surface of a rigid panel. Suitable application procedures are given in Test Methods D 823.
5.2 Use surfaces of good planarity because warpage, waviness, or curvature may seriously affect the measure ments of gloss and color and may produce a poor air seal on the black box rack.
5.3 Control specimens shall be prepared for inclusion in each exposure series to act as comparison standards and to provide a means for determining the severity ofthe exposure conditions encountered by the series. For best results, there should be at least two controls differing significantly in their durability performance.
5.4 Using Test Methods D 1186, measure the dry film thickness of the coatings at several different positions on the test and control specimens.
PROCEDURE A--BLACK BOX EXPOSURE

It is Wksponsibility of the user of this standard to establish Wpriate safety and health practices and determine the mobility ofregulatory limitations prior to use.
g||mmary of Method

Significance and Use
Coatings intended to be cured by ultraviolet radiation, pDy those involving free radical chemistry, tend to 1%Wze during storage. It is ofinterest to determine how
j|| fonnulation resists this effect. Many factors influence ~ storage stability of a composition. The procedures Jfed here are intended to improve the precision of
lining this property. Because the effects of resins, 3g|ners, photoinitiators, synergists, stabilizers, or pigM can alter the relation between elevated and room gpature stabilities, any correlation of performance at Afferent temperatures is possible only with a given Jjlhtion and, therefore, is useful only for quality control.

5.1 Clear Coatings:
5.1.1 Fill three 4-oz (115-mL) wide-mouth jars to Vain. {6 mm) from the top. Add a small glass or porcelain sphere to each container and put the lids on tightly.
5.1.1.1 The amount ofhead space in ajar or can is critical because the volume of air in contact with the sample has an effect on the rate of polymerization. The stability is also related to the ratio of the area of liquid-air interface to the volume of liquid.
5.1.2 Put twojars in an oven at 60 2C. Retain the third at ambient temperature, 25 2C, and in the dark.
5.1.3 Check an oven jar daily but do not open or invert. Rather, tip slightly, no more than 30, to determine the extent of polymerization by noting the mobility of the sphere. When gelling is noticed, check the second jar to confirm.
5.1.4 Record the duration of the test in days. Indicate the last day the sphere is mobile followed by the first day it is immobile, and if the days are not consecutive, why the interval occurred.
5.1.5 Check the jar stored at room temperature every week-but do not open or invert. Tip slightly, no more than 30, to determine if the sphere is immobile.
5.1.6 Record the number of weeks not gelled followed by the first week the sphere is immobile.
5.2 Pigmented (Opaque) Coatings: 5.2.1 Fill twelve 4-oz (115-mL) lined cans to lA in. (6 mm) from the top and put the lids on tightly. 5.2.1.1 See 5.1.1.1. 5.2.2 Put six of the cans in an oven at 60 2C. Retain six cans at ambient temperature, 25 2C. 5.2.3 After one day remove one can from the oven, open, and probe to the bottom to determine if gelling is beginning. Discard the can after the test. Check one of the remaining cans on the 2nd, 4th, 8th, 16th, and 32nd days and discard after testing. By starting on a Monday all the testing will fall on normal working days. 5.2.4 Record the condition of the specimen each day tested, indicating the fractional amount of any gelled mate rial present.
5.2.5 After one week check one of the cans held at ambient temperature by opening and probing to the bottom to determine ifgelling is beginning. Discard the can after the test. Check one ofthe remaining cans after 2,4,8,16, and 32 weeks.

4 Scope
ll This test method describes a procedure for deterliimg the flexibility and adhesion of organic coatings tints) on metallic substrates that are deformed by bending ,en the sheet is fabricated into building panels or other
duets. E,2 The metal substrate must be capable of passing, this es[ without fracturing and with no excessive grain developItnt. :
This standard does not purport to address the safety uhlans associated with its use. It is the responsibility ofthe
of this standard to establish appropriate safety -and iuth practices and determine the applicability ofregulatory
nions prior to use.
BTenninology
1 Description of Term Specific to This Standard: fl I ' T-bend--a description of the severity of a bend in finis of the thickness (T) of the sheet to which the coating
been applied; as used in this test method, the T-bend ng is the minimum number of thicknesses of metal li'nii d which the coated sheet is bent (Fig. 1); or if bent i id a die, the number of thicknesses ofmetal equivalent he diameter of the die to achieve no fracture or removal he coating.
Summary of Test Method
3.1Prepainted panels are bent 180 around progressively re thicknesses of meial or larger diameter dies, the end ini being when failures no longer occur. The panels are 'jammed at low magnification (5 to lOx) after each'bend for ture of the coating (cracking) and, for loss of adhesion choff, by means of a tape pull-off test.
Significance and Use
p.l Organic coatings on precoated sheet are subjected to s,,<.s when fabricated into products by roll forming, brake
fcpnJ'ng, or other deformation processes. These stresses can ed the flexibility or adhesive strength of the coating,
suiting in fracture of the coating, exposing the substrate, or it adhesion to the substrate. This test is a means of
Ifaluating the ability of a coating system to withstand the fcho'.st.s of fabrication.
Tins test method is under the jurisdiction of ASTM Committee D-J on Paint Jd Related Coatings and Materials and is the direct responsibility of Subcom-Jpttcc DO 1.53 on Factory-Prccoated Strip Metal. liPCuTrem edition approved March 25, 1983. Published July 1983.
4.2 The bend direction, whether the axis of bend is across or along the rolling diameter of the metal, and the tempera ture of the specimen when it is bent affect the results of this test and should be agreed upon between the supplier and the user.
5. Apparatus
5.1 A means of holding one end of the specimen rigidly while making the bend is needed. A bench vise with smooth jaws or with smooth inserts, preferably of a soft metal to avoid damage to the coating, has been found to be satisfac tory.
5.2 If the metal is not bent around itself as in Fig. 1, a series of bending dies with smoothly rounded ends may be used as guides around which the specimen is bent (Fig. 2).
5.3 Magnifier, capable of 5 to lOx magnification for examining the specimen for coating fracture and pickoff after testing. A stereomicroscope has been found useful for this purpose.
6. Procedure
6.1' Bending the Coated Specimen Around Itself. 6.1.1 The coated specimen shall be at least 2 in. (50 mm) across the bend direction, by a length sufficient to make the required number of bends. A 2 by 6-in.'(50 by 150-mm) size is convenient. The specimen shall be at 2F of the temperature agreed on.
N' --A triangle-shaped specimen (Fig. 3) has been found conven ient for making T-bend-tdsts. This shape leaves a portion of each bend exposed for later examination and for a permanent record.
6.1.2 Secure about 0.5 to 0.75 in. (13 to 20 mm) of one end of the specimen in a vise or holding jig as shown in Fig. 1. Bend the free end of the specimen 90 in a smooth and uniform manner so that the coating is on the outside of the specimen after it is bent.
6.1.3 Continue to bend the specimen until the bent end can be inserted in the jaws of the vise. Tighten the vise to complete the 180 bend, which is called an OT bend. Take care to tighten the vise sufficiently so that the apex of the bend is as flat as can be reasonably achieved.
6.1.4 Examine the bend using a hand lens or low-power microscope for cracks in the coating.
6.1.5 Apply pressure-sensitive tape2 along the bend. Rub the tape flat; then, holding the specimen firmly, remove the
2 Scotch Brand #610 tape manufactured by 3M Co., St. Paul, MN or equivalent, or as agreed upon between the supplier and the user.

Designation: D 4146 - 83 (Reapproved 1989)*
Standard Test Method for Formabiiity of Zinc-Rich Primer/Chromate Complex Coatings on Steel1
This standard is issued under the fixed designation D 4146; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicatestheyearoflast rcapprova! A superscript epsilon () indicates an editorial change since the last revision or reapproval.
e 1 N' --Editorial changes were made throughout in March 1989.
1. Scope
1.1 This test method covers the evaluation of the formability and adhesion of factory applied zinc-rich primer/ chromate complex coatings on steel with thicknesses of0.025 to 0.05 in. (0.65 to 1.25 mm) typical of those used in the coil coating industry.
1.2 The degree of oil removal prior to forming, the techniques of taping, and differences in adhesive strength of the tape can affect the adhesion rating.
1.3 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Description of Terms Specific to This Standard: 3.1.1 dome height--the height ofthe dome formed in the test. 3.1.2 indenting ball diameter--the diameter of the spherical-ended penetrator (ball) used to deform the specimen. 3.1.2.1 Discussion--The l5/s-in. (41-mm) diameter ball was selected because it minimizes the variability in the localized peak strain. This size ball is commercially available and is as large as most testing machines can accommodate. 3.1.3 percent strain--the percent elongation of scribed gage lengths after forming. For the draw height of 0.512 in.
(13 mm), using a l5/s-in. diameter ball, the localized peak strain is about 19 % (see Fig. 1).
4. Summary of Test Method 4.1 A coated specimen is biaxially stretched a given
distance in an appropriate machine, adhesive tape is applied to the deformed area (dome) and then pulled off, and the amount ofcoating removed is compared with a photograpine standard to determine the coating adhesion rating.
5. Significance and Use 5.1 The results of the combined deformation and tape 1 est
are related to the ability of the coated metal to withstaui! stamping in factory applications.
5.2 This test can be used to control the manufacturing process or in development work to improve the product.
5.3 It should be recognized that variability in the results1,1 persist due to the test conditions and forming machinevariations.

, dimension. Strips of full width of the coil can be tested if precautions are taken not to nick or damage the adjacent dome in the machine. 8.3 Specimen Thickness--Thicknesses should be 0.025 to 0.05 in. (0.64 to 1.25 mm). With thicknesses less than 0.025 in., fracture of the steel may occur, in which case the dome height can be reduced if agreed upon between the supplier and the user of the sheet product. When thicknesses greater than 0.05 in. are being tested, die modifications may be needed, but such modifications require agreement between the supplier and the user. 8.4 Test specimens shall be free of oil, grease, lubricants, rust/and burrs that may affect the holding pressures or dome height. 8.4.1 Typically a light spindle oil is applied to reduce corrosion on the uncoated side of the coil. 8.4.2 Remove oil, grease, and lubricants by one of two methods, as agreed upon between the supplier and the user. Either heat the specimens to 300F (I50C) for 30 min or wash them in a cleaning solution0, rinse with tap water, and dry. As the solution can become contaminated with oil, do not wash more than 50 panels per gallon of solution.
9. Procedure
9.1 Condition the specimens for at least 24 h at 73.5 3.5T (23 2C) and 50 5 % relative humidity before conducting the test, unless otherwise agreed.6
6 This is one cleaning solution that is used. Add 10 g of Car Wash Concentrate, a product of Borden Inc., Chemical Div., 180T E. Broad St., Columbus, OH 43215 (product formerly called DuPont No. 7 Car Wash), per gallon (2.6 g/L) of water at a temperature of I00*F (40'C).

9.2 Place the specimen in the machine so that the coating
to be tested will be on the convex side of the dome away from the punch.
9.3 With the ball touching the uncoated side of the specimen and the dial gage indicating zero penetration at the start of the test, indent the specimen with the ball to a distance of 0.512 in. (13 mm), ensuring that the hold-down pressure does not decrease during forming of the dome and that there is no evidence of slippage of the specimen under the hold-down dies during the test. The speed of forming the domes is done in accordance with 6.1.1.
9.4 Return the ball to the original position, remove the specimen from the machine, and lay it on a flat surface.
9.5 Apply the tape over the peak of the dome, press firmly, and then pull the tape from the dome at a fast, steady rate. The 1-in. (25-mm) wide tape will not fully cover the dome and will wrinkle at the edges.
9.6 Place the tape on a piece of white paper, compare the amount of coating on the tape with the photographic standard, and estimate coating adhesion to the nearest whole number. In Fig. 3, areas of darkness are coating removal so that a tape rating of No. 10 is perfect adhesion and No. 0 is complete removal ofthe coating. Wrinkles in the tape can be seen in the photographic standards as light areas.
9.7 Typically, a full-width specimen is cut from each coated coil and tested at three areas along the strip. Usually, domes are made at both edges and the center of the coated
full width strip.
10. Report
10.1 Report the following information: 10.1.1 Identification of the material such as coil number and location of the specimen within the coil, 10.1.2 Specimen thickness, 10.1.3 Number of tests or domes evaluated, and 10.1.4 Adhesion rating including mean, range, or standard deviation, if applicable.
11. Precision
11.1 On the basis of an interlaboratory study of this test method, in which one operator in each of three laboratories tested five separate panels cut from the same coated steel, the within-laboratory standard deviation was 0.61 units with 12 df and the between-laboratory standard deviation was 0.35 with 2 df. Based on these standard deviations, the following criteria Should be used for judging the acceptability of results at the 95 % confidence level:
11.1.1 Repeatability--Two results obtained by the same operator should be considered suspect if they differ by more than 2 rating numbers.
11.1.2 Reproducibility--Two results, each the mean of two determinations, obtained by operators in different labo ratories should be considered suspect if they differ by more than 2.9 rating numbers.

Summary of Practice r.rf.1 A flat panel is secured on a firm horizontal surface,
tample amount of coating is poured across one end of the el and the drawdown bar placed behind the coating. The
j is then drawn uniformly along the length of the panel Sard the operator to apply a uniform film. The dry film Ipcness obtained is dependent on the combination of the "j used, the volume solids of the coating, and the speed of > drawdown motion.

5. Safety Precautions
5.1 The flash points ofmost solvents used in coatings and related products are low enough that adequate ventilation is needed to avoid exceeding 25 % ofthe lower explosive limits of the solvent when preparing and baking the panels. As these solvents could be toxic, care should be taken to avoid inhalation of the vapors and unnecessary contact of the solvents with the skin.
6. Procedure
6.1 Deburr panels so edges are smooth. Secure a flat panel to be coated on a firm, uniform, level surface. To provide sufficient testing surface pour an ample amount of coating across the end of the panel. Place the drawdown bar behind the coating and pull into the coating. Rotate the drawdown bar 30 to 60in the coating to ensure complete wetting ofthe coating in the threads of the bar. Apply moderate pressure equally to both ends ofthe drawdown bar and hold it firmly without allowing rotation. Using only one pass, draw the bar along the length of and off the panel at a uniform speed so that a continuous film is produced. The drawdown speed is dependent on the rheology and type of the coating being used. Remove the coated panel and bake, force dry, or air dry the coating in accordance with its type so its dry film thickness can be measured. A heavier film thickness is obtained along the edges of the panel and possibly at the top of the panel where the coating was poured. For a two-coat system, the side edges must be trimmed to eliminate the heavier areas on the first coat before applying the second coat.

Standard Test Method for Sustained Burning of Liquid Mixtures by the Setafiash Apparatus (Open Cup)1
This standard is issued under the fixed designation D 4206; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This test method may be used in conjunction with a flash point determination. If the flash point of a mixture of flammable and nonflammable liquids or liquids of widely different flash points is below the upper limit of a flammability classification (for example, 100F specified by the U.S. Department of Transportation), this test may be conducted to determine the sustained burning characteristics of the mixture.
This test method is a modification of the test for combustibility now incorporated as-Schedule 2 ofthe "Highly Flammable Liquids and Liquified Petroleum Gases Regulation, 1972" ofthe United Kingdom under The Factories Act, 1961, which is also issued as British Standard BS-3900, Part A-l 1, Small Scale Test for Combustibility. This sustained burning test was studied andproposed by the ASTM Coordinating Committee for Flash Point and Related Properties. The major purpose of this test is similar to that of the British test--to provide a method for determining the sustained burning characteristics by directly observing this property rather than by deducing them from the flash point,
jgicope il This test method2 describes a procedure for deter-' ling the sustained burning characteristics of mixtures of pmable and nonflammable liquids and also mixtures gaining liquids with widely different flash points.
2 This standard should be used to measure and describe properties of materials, products, or assemblies in repse to heat and flame under controlled laboratory condi|ps and should not be used to describe or appraise.thefire yard orfire risk ofmaterials, products, or assemblies under .`ual fire conditions. However, results of this test may be ' as elements of a fire risk assessment which takes into
nl all ofthefactors which are pertinent to an assessment efire hazard ofa particular end use. $ This standard may involve hazardous materiab, operfis, and equipment. This standard does not purport to 'ress all ofthe safety problems associated with its use. It is responsibility of the user of this standard to establish jropriate safety and health practices and determine the plicability ofregulatory limitations prior to use.

3. Summary of Test Method
3.1 A block ofaluminum alloy, or other nonrusting metal of suitable heat conductivity, with a concave depression (called the well) is heated to the required temperature of 120F (49C). A standard source of flame, capable of being swung over the center of the well and at a given distance from it, is attached to the metal block.
3.2 Two millilitres of the product under test are trans ferred to the well. After the product has reached the stated temperature, the flame is passed over the well, held there for a specified time, and then removed. The time of sustained burning is then noted.
4. Significance and Use
4.1 Mixtures of flammable liquids and nonflammable liquids, such as an alcohol and water mixture, are classified by the U. S. Government by the definition of flammable liquid based on a closed-cup flash point method. Thus, mixtures may be classed as flammable even though they do not sustain burning. This test method determines the ability of a liquid mixture to sustain burning and, when used with a closed-cup flash point method, indicates the flammability characteristics of the mixture.

block of suitable heat conductivity fitted with a concave depression or well (Note). The metal block has a thermom eter embedded in it. A small gas jet on a swivel is attached to the metal block. The exact dimensions of the metal block and its well, the gasjet and its positioning, and the embedded thermometer are shown in Fig. 1 and are specified in Annex AI.
N' --While the Setaflash Open Cup Tester is generally made of an aluminum alloy, continued use of it for sustained burning tests rnay produce a carbon deposit in the well which may be difficult to remove without damaging the aluminum well. The stainless steel well may be cleaned with crocus cloth.
5.1.1 Gage--A metal strip, capable of checking the height ofthe gas jet above the top of the well lip (2.2 0.1 mm).

6.1 Obtain a representative sample of the 'product under test, mixing it thoroughly, especially if it has a tendency to layer, and keep in an airtight container.
6.2 Because of the possibility of loss of volatile constitu ents, the sample should receive only the minimum treatment
to assure uniformity. After removing the specimen, immedi ately close the sample container tightly to assure that no volatile flammable components escape from the container. (Otherwise a new sample may be necessary.if further testing is required.)
6.3 Do not open containers unnecessarily. Do not make transfers unless the sample temperature is at 100T (37.8C) or below, except for samples that are too viscous to be handled at that temperature. In these cases, transfer the samples at the lowest possible temperature at which the sample can be accurately measured into the cup.
6.4 Discard samples in leaky containers. 6.5 Do not store samples in plastic (polyethylene, poly propylene, etc.) bottles, since volatile material may diffusthrough the walls of the bottles. -
7. Correction for Barometric Pressure
7.1 When the barometric pressure differs from 760 mm Hg (101.3 kPa), determine the temperature at which the test should be conducted by the following equations:
F = 120*F- 0.06 (760- P) C = 49C - 0.03 (760 - P) ' '/ = 120T- 0.42 (101.3 -B)
C = 49"C-0.23 (101.3-if)
where: F,C = temperatures to obtain the equivalent of 1207
(49C) at standard pressure, P barometric pressure, mm Hg, and B = barometric pressure, kPa.

Standard Test Method for Viscosity by Dip-Type Viscosity Cups1
This standard is issued under the fixed designation D 4212; the number immediately following the designation indicates the year of original adoption or, in the case of revision, Ihe year oflast revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<} indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers the determination of viscosity of paints, varnishes, lacquers, and related liquid materials by dip-type viscosity cups. This test method is recommended only for viscosity control work within one plant or labora tory and should not be used to check compliance with specifications.
1.2 Viscosity cups are designed for testing of Newtonian and near-Newtonian liquids. If the test material is nonNewtonian, that is, shear-thinning or thixotropic, another method, such as Test Methods D 2196, should be used.
1.3 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

Newtonian Materials by Rotational (Brookfield) Vis cometer2 D4287 Test Method for High Shear Viscosity Using the ICI Cone/Plate Viscometer2 E 1 Specification for ASTM Thermometers3
3. Terminology
3.1 Definitions: 3.1.1 near-Newtonian liquid--a liquid in which the varia tion of viscosity with shear rate is small and the effect on viscosity of mechanical disturbances such as stirring is negligible. 3.1.2 Newtonian liquid--a. liquid in which the viscosity is independent of the shear stress or shear rate. If the ratio of shear stress to shear rate is not constant, the liquid is non-Newtonian.
4. Summary of Test Method
4.1 The cup is completely immersed in the material to be tested, withdrawn, and the time for the material to flow through a hole in the base of the cup is measured.
5. Significance and Use
5.1 Viscosity is a measure of the fluidity of a material. Viscosity data are useful in the determination of the ease of stirring, pumping, dip coating, or other flow-related proper ties of paints and related fluids.
5.2 This type ofcup is used to measure viscosity because it is easy to use, robust, and may be used in tanks, reservoirs, and reactors.
5.3 There are other types of apparatus for measurim viscosity in the laboratory that provide better precision a in bias, including the Ford viscosity cup (Test Method D 120b) and the Brookfield viscometer (Test Methods D 2196).
5.4 Certain higher shear rate devices such as cone/plate viscometers (Test Method D 4287) provide more informa tion about sprayability, roll coatability, and other high-sheai rate related properties of coatings.

8.1 Measurements should be made at 77F (25C) unless otherwise specified. Temperature drift during the test should be kept to a minimum. The viscosities of paints and related materials are highly dependent on temperature. Differences in temperature between measurements can give substantially different viscosities (up to 5 % per F) . For careful work, the

9. Checking and Calibration of Cups
9.1 Cups should be checked in accordance with the procedure described in Appendix X2. The frequency of this depends upon the amount of use and care that the individual cup receives.
9.2 Cups may be calibrated with standard oils according to the procedure in Appendix X3. However, because of the great temperature dependence of the viscosity of standard oils and the lack of adequate temperature control with dip cups, calibration is a difficult and often inaccurate procedure that must be done with great care. Because of the wide variability in Zahn cups, checking rather than calibration is recommended.
10. Procedure
10.1 Choose the proper cup so that the time of efflux will be between 20 and 80 s. See Table 1 for viscosity ranges for the various cups.
10.2 Immerse the cup in the container, which may be a can or beaker, but is more likely to be a thinning or mixing

tank or even a resin reactor. Stir or agitate the fluid well to give uniform temperature and density. Allow the cup to remain in the fluid for 1 to 5 min to attain thermal equilibrium. (Because of their greater mass, Shell cups should remain in the fluid for the full 5 min.)
N' 2--Dip cups are not recommended for use with thixotropic
(time dependent) materials but if used for them (such as gravure oti flexographic inks), more vigorous agitation will be necessary to break up' the structure before the measurement is made.
10.3 Lift the cup vertically out of the material in a quick, steady motion. As the top edge ofthe cup breaks the surface, start the timer. During the time of flow hold the cup t vertically no more than 6 in. above the level of the liquid. ' Stop the timer at the first definite break in the stream at lli base of the cup. The efflux time in seconds constitutes l viscosity. It is common to make only a single measureme but for greater precision and accuracy the mean of two more measurements should be taken.

XL ZAHN CUP DESIGN, MANUFACTURE, AND USE
SCI. 1 Zahn cups were designed (and made by General jlcs-tric) as simple flow property devices for use in dip tanks,
coat reservoirs, etc. They never were meant to be Ifcojnctcrs or to be used as such. Zahn cup use usually Trolves thinning or maintaining a coating, adhesive, or ink
'tcertain consistency (so many Zahn-seconds) regardless of jemperature. This is the beauty of dip cups. The operator iuows that his or her tank, bath, or coater runs well over a certain range of Zahn-seconds whether the plant temperature s SOT or 100T. The operator does whatever is necessary to
JSep the fluid within the range. He or she does not care what 4jdic viscosity is at 25.0'C (77.0"F).
XI.2 Because the Zahn cup patents have long since run out, the cups can be made by anyone. Each manufacturer makes cups that are somewhat different from those made by others. Considerable batch-to-batch difference from any given manufacturer has been seen in tlie past. Cup variations are not a problem for control of a bath or tank as long as new cups are compared to old ones for the Zahn cup-seconds operating window and a new window is established if necessary. However, cup differences cause great difficulty if cups are used to set producer-user specifications. Compari sons are almost impossible under such conditions.

X2. DIP CUP CHECKING PROCEDURES
X2.1 Because Zahn cups vary with the manufacturer and batch, it is not possible to set up calibration equations that are applicable to all cups. Therefore, the only procedures that are recommended checking a cup against its original efflux time or comparing one cup against another. However, if a cup owner has an absolute compulsion to calibrate a Zahn cup, there are equations available (see X3). Shell cups may be checked by the same procedures as Zahn cups or may be calibrated.
X2.2 Monitoring Cup Characteristics--A useful checking technique is to measure the efflux time for a new cup with a given standard oil, then check the cup periodically with the same oil at the same exact temperature to see whether the efflux time has changed. If the time changes drastically (greater than 20 %), the cup should be replaced. Ifthe change is small, the cup can be used as is or a correction can be made in subsequent efflux times of paints or other materials. The correction factor is equal to original oil efflux time divided by the current one. Recommended oils for such tests are given in Table X2.1. The viscosity of oils is very sensitive to temperature variations and, therefore, the temperature of the oil must be controlled closely during testing. It is recommended that the oil be held at the test temperature for at least 15 min prior to testing.
X2.3 Comparing Cups--It sometimes is necessary to compare one Zahn cup with another in order to settle a dispute, determine whether a new cup will give similar times to an old one, etc. The most usual technique is to dip both

X3.1 Select the appropriate standard oil for the cup to be checked (see Table X2.1).
X3.2 Bring the cup and the standard oil to a constant temperature as close as possible to 77.0F (25.0'C). Deter mine the time of efflux to the nearest 0.2 s using the procedure detailed in Section 10. Record the temperature of the efflux stream. If it is not 77"F, correct the viscosity of the standard oil to the actual temperature.
X3.3 Convert the time of flow in seconds to kinematic viscosity as follows:
V=K(t-c)
where: F = kinematic viscosity, cST t = efflux time, s, and, K, c = appropriate constants (front Table X3.1).

7. Preparation of Apparatus
7.1 Scrub Test Apparatus--The scrub machine should be leveled before use and operated at 37 1 cpm. Before each test check the tightness of the motor belt or chain drive and alignment of the cables in both horizontal and vertical planes. Adjust tautness of the cables with the accessory spring scale to approximately 5 !b.
7.2 Cut the sponge to fit the standard brush holder, 3% by \lh by 1 s/s in. (95 by 38 by 40 mm). New sponges should be saturated with reagent water, wrung dry by hand and allowed to equilibrate in a constant temperature and humidity room for 24 h before being cut.
7.3 Brush Holder--Add sufficient weight to the holder in the form of sheet lead or other fiat weights to total 500 10 g including the sponge.

8. Procedure
8.1 Stir the material under test thoroughly and strain to remove all skins and particles. Clean the top ofthe glass plate (or preferably suction plate) and both sides of the black plastic panel to be sure they are free of specks. Place the black panel on the plate and tape one end to the plate. Smooth the panel along the plate by rubbing with flannel, creating static electricity to improve adhesion to the plate.
8.2 Drawdown the paint on the panel using the 10-mil (0.25-mm) side of the film caster, starting as close to the taped end of the panel as possible (should be less than Vi in. (13 mm) from the taped end of the panel). The time of application should be fairly slow--3 to 4 s from end to end--to prevent formation of pinholes or holidays in the film. Air dry in a horizontal position for seven days in an open room, preferably kept at 73 3.5F (23 2C) and 50 5 % relative humidity.
8.3 After the specified drying time, cut off the top % in. (20 mm) of the panel, preferably with a paper cutter to
13 Hydroxcthylceliulose having a molar substitution (MS) value of 1.8 to 2.5 and a viscosity of a 2 % solution in the range qf 4400 to 6500 cPs., Cellosize QP-4400, obtainable from Union Carbide Co., Chemicals Div., 270 Park Ave., New York, NY 10017, has been found satisfactory for this purpose, as well as Natrosol 250 MR obtainable from Hercules Inc., 910 Market St., Wilmington, DE 19899.
14 This silica is an amorphous grade of 99+ % silicon dioxide giving a pH of 6.8 to 7.2 in reagent water.

ensure a smooth straight edge. The film should now cover the panel uniformly along its entire length, exactly 16`A in. (413 mm). The panel may now be cut in half, length-wise? so that duplicate tests can be run. Roll the test panels into the shape of a cylinder to fit the balance pan, fasten the ends together with a paper clip and weigh to 1 mg. Record this as Weight A. Remove the clip and carefully unroll the panel. Save the paper clip for later weighings. Avoid any damage to the film after weighing.
8.4 Clean the glass plate and set it in the pan of the scrub test apparatus. Place the test panel, with painted side up, over
the glass plate so that the test area is level. Pre-wet the gasket ofthe frame (if frame is to be used), and wipe dry before use. Place the frame over the drawdown and clamp in place. Clamps should be tight enough to ensure close contact but not tight enough to cause warping of the panel.
8.5 Place the sponge in reagent water and allow to remain for 30 min. Remove, hand squeeze dry, and insert in the weighted holder. Stir the scrub medium and spread 10 g evenly over the face of the sponge. Place the sponge at the end ofthe panel and wet the path of the sponge on the panel with 5 mL of water.
8.6 Note counter reading on scrub test apparatus and start the test. Make sure the sponge travels only over the test panel and only over the coated portion of the panel, and that sponge and holder are level during run. If the sponge and carriage tend to tilt sidewise, twist the cable in the direction in which the holder is tilting to impart an opposing torque to the sponge and holder enabling them to ride upright.
8.6.1 Caution--Cables should not be twisted more than three or four times. Excessive twisting in the direction opposite to that used to form the cable can cause unraveling of cable strands.
8.7 After each 100 cycles examine the panel for erosion through to the substrate. If cut-through is evident, stop the test and record the number of cycles. Otherwise continue until 400 cycles, at which time add 10 g of stirred medium to the sponge again and 5 mL of water to the panel, and continue testing to a maximum of 1000 cycles. Add 10 g scrub medium and 5 mL deionized water at the end of every 400 cycles.
8.7.1 In instances where cut-through is observed, repeat the test using the other half of the test chart and stop at least 100 cycles short of the previously noted cut-through point. It is important not to erode the film to the point where the substrate shows through since this will cause an erroneous result.
8.8 Rinse off the panel with tap water making sure all scrub medium has been removed, brushing gently with a soft camel hair brush to facilitate removal of the scrub medium. Blot the panel (do not rub) with paper towels, allow to air dry for 30 min, and then place flat in the oven at 120 to 130F (50 to 55C) for 30 min. Remove and allow to equilibriate for 15 to 20 min preferably in a conditioned room, or if necessary at ambient conditions surrounding the balance. Roll the panel into a cylinder, dip the edges together with the paper clip used in the initial weighing, and weigh to 1 mg. Record this as Weight B. Then calculate the Erosion Rate C in accordance with 9.1.
8.9 Between runs, rinse the sponge thoroughly to remove as much detergent as possible, soak the sponge in reagent
water before the next test, and then proceed as in 8.5.
8.10 Make three drawdowns from each sample. Test two
panels (four tests), then calculate the mean value of C and report this value unless any of the results differ by more than 25 % ofthe mean. Ifthey do, test the third panel and include the two results in the mean unless one of the results is
obviously discrepant, in which case it should be discarded.
N' 2--See Table 3 of Practice D 3980 for limits used in rejecting
extreme values.
8.11 Determine the density (D) of the paint in g/mL, in accordance with Test Method D 1475.
8.12 Determine the percent nonvolatile by weight, (W), of the paint, in accordance with Test Method D 2369.
9. Calculation
9.1 Determine the total weight loss in milligrams for each panel by subtracting B from A. Divide the weight loss by the number of cycles and multiply by 100 to determine the erosion rate C expressed as milligrams lost per 100 cycles, thus:
(A - B) x 100
number of cycles
9,2 Calculate V, the percent nonvolatile by volume of the paint as follows:
9.2.1 Water-borne Paints--V = 100 -- D(100 -- W) 9.2.2 Solvent-borne Paints--V - 100 -- 1.2823(100 - W) 9.3 Calculate the erosion rate in terms of wet film volume, thus:
microlitres _ 100 C 100 cycles -- WD
N' 3--This value relates to the whole paint and is thus analogous,
though inversely, to the cycles-to-failure values of Test Method D 24Sf
9.4 Calculate the erosion rate in terms of dry film volume,, thus:
microlitres _ CV 100*cycles ~ WD
N' 4--This value relates to the nonvolatile portion of the paint
The film volume in the equation is exclusive of interstitial air, whether due to vesiculated beads or ordinary porosity.
10. Report
10.1 Report the following information: 10.1.1 Erosion rate of the equivalent wet film tot* microlitres/100 cycles, as calculated in 9.3. 10.1.2 Erosion rate of the dry film in microlitres/100 cycles, as calculated in 9.4 10.1.3 Number of tests. 10.1.4 Number of cycles at which any erosion to tht substrate initially occurred. 10.1.5 Any deviations from the standard procedure.
11. Precision
11.1 In an interlaboratory study of this test method in' which operators in six laboratories tested three latex coatings covering a range of pigment volume concentrations, the'within-laboratory coefficient of vartiation was found to 5.6 % and the between-laboratories coefficient 9.4 %. Based

3.1 Definition: 3.1.1 chalking--the formation on a pigmented coating of a friable powder evolved from the film itself at or just beneath the surface.
1 These? test methods are under the jurisdiction of ASTM Committee D-l on Paint and Related Coalings and Materials and are the direct responsibility of Subcommittee D01.27 on Accelerated Testing.

4. Significance and Use
4.1 The procedures provide a broader range of techniques and photographic references to evaluate chalking of exteriopaints than that in Method D 659 and are thus an extension of that method.
5. Type of Chalking
5.1 Only one type of chalking is recognized, as defined in Section 3.
6. Use of Photographic Reference Standards
6.1 The photographic reference standards that are part of this test method are representative of the degrees of chalkinjon a paint film. The photographs shown in Figs. 1 and 2 ari for illustration purposes only and should not be used foevaluation.
6.2 The use of photographic reference standards illus trated in Figs. 1, 2, 3, and 4 requires the following precau tions:
6.2.1 The degree ofchalking will vary over any given area. Therefore, an average portion ofthe coating should be evalu ated. On large surfaces, it is recommended that the rating be made at several locations and the mean and range reported
6.2.2 It is difficult to make readings on a windy day and making readings at such time should be avoided. It should 'l also be noted that rain, snow, or moisture in any form v tl remove chalk so that readings should be made after a pet too of clear weather and when the surface is dry.
6.2.3 Chalking and erosion (Note 1) are closely rela' 1 and erosion is a result of chalking failure. However, the rate j of chalking as measured by these test methods, and the nut of erosion may not be comparable because some pigment" combinations tend to retain chalk on the surface while othecj pigment combinations exert a self-cleaning action by naturali| means.
N' l--For the evaluation of erosion, see Test Method D 662
6.3 Records may be kept on forms such as shown in 1 tc 3, according to Standard D 1150, or other inspection forms The reporting of the results shall include the informal tor given in Section 10.
6.4 When this test method is referenced in specifications fij for performance, the permissible degree of chalking established between the producer and the user.

If values have changed, restandardize and ord values before proceeding to the remaining tapes. Bowing the final tape measurement, record reflectance dues ofthe clear plastic sheet cover and the white and black fectance standards. '8.2.5.3 Subtract the mean reflectance value of the sheet m each reading, enter on worksheet form (Fig. 4), or other prm used, and determine from Table Is the chalk rating (flue of each tape to the nearest 0.5 unit. Record the rating the worksheet or other form. The worksheet form (Fig. 4),
inserted into the plastic sheet protector with a black back ground gives a clear permanent record of these measure ments and evaluations.

8.3.1.1 Photographic Reference Standard No. 2 for the determination ofchalking, consisting of a photograph of five strips of tape mounted on a black background, numbered 0, 2,4, 6, and 8, and varying in this order from white to almost black. The numerical rating of chalking shown on the photographic reference standard is opposite of the original TNO Scale.
8.3.1.2 Polyethylene Tape,9 transparent, 1-in. (25-mm) wide.
8.3.1.3 Black Velvet, dull black with a short pile and without a tendency to crush, size approximately 8 by 12 in. (200 by 300 mm), mounted on a flat substrate. Place adjacent to the standard for the ratings.
8.3.2 Procedure--Apply a piece of tape, approximately 4-in. (100-mm) long, to the coating by uniform gentle
pressure of the finger, remove the tape, and lay it with the adhesive side on the piece of velvet. Under diffused light compare the tape on the black velvet with PhotogfaphiC Reference Standard No. 2, and determine which of the five grades most closely matches the whiteness of the adhering pigment. If the degree of chalking is obviously between two adjacent grades, select the intermediate odd number as the chalk rating.
8.3.3 Chalk ratings may also be determined by following the procedures of 8.2.3 and comparing to the values showil in Table 1. The use of the worksheet form shown in Figs;'3 and 4 may be used as a permanent record.

Standard Practice for Labeling Art Materials for Chronic Health Hazards1
This standard is issued under the fixed designation D 4236; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (0 indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Uninformed or careless use of some art material products can give rise to health hazards, either acute or chronic, or both. Specific and readily available warnings are needed to help protect users of any age. One way to disseminate such information is to provide appropriate precautionary labeling on art material products.
Labeling for acute health hazards, including those associated with art materials, is being addressed by such requirements as the U.S. Consumer Product Safety Act, the Federal Hazardous Substances Act, and the like. There are presently no specific national standards for labeling art materials with respect to chronic health hazards.
This practice is intended to provide a standard for developing precautionary labels concerning chronic health hazards related to the use of art materials. It is further intended to have the adaptability necessary to keep labels current with existing scientific and medical knowledge, as well as in conformity with Other precautionary labeling requirements, both acute and chronic, thereby avoiding unnecessary confusion by users with respect to other precautionary labeling.
Scope
111 This practice describes a procedure fof developing autionary labels for art materials and provides hazard precautionary statements based upon knowledge that ; in the scientific and medical communities. This plac-
; concerns those chronic health hazards known to be assowiih a product or product component(s), when the
Iponent(s) is present in,a physical form, volume, or conatration that in the opinion of a toxicologist (see 2.1.11) 5 the potential to produce a chronic adverse health effect(s), jj.,2 This practice applies, exclusively to art materials ckaged in sizes intended for individual users of any age or
: participating in a small group. Labeling determinations shall consider reasonable
eable use or misuse. The responsibility for precaulabeling rests with the producer or repackager who
ets the materials for art or craft use. '1.4 This practice does not specify test methods for deter-
ng whether a substance or product presents chronic Ihealth hazards.
rl.5 This practice does not apply to products appropriately I labeled for known chronic health hazards in accordance with [chemical substance labeling standards and practices, such as
another national consensus standard, existing labeling stats utes, regulations, or guidelines.
1.6 Since knowledge about chronic health hazards is incomplete and warnings cannot cover all uses of any prodmet, it is not possible for precautionary labeling to ensure

completely safe use of an art product. 1.7 Manufacturers or repackagers may wish to determine
individually or collectively precautionary labeling for art materials in accordance with this practice. Compliance may be certified by a certifying organization. Guidelines for a certifying organization are given in Appendix XL
1.8 This standard does not purport to address all of the safely problems, if any, associated with its use. ft is the responsibility ofthe user ofthis standard to establish appropriate safety and health practices and determine the applica bility ofregulatory limitations prior to use.
2. Terminology
2.1 Descriptions of Terms Specific to This Standard: 2.1.1 analytical laboratory--a laboratory having per sonnel and apparatus capable of performing quantitative or qualitative analyses of art materials, which may yield infor mation that is'used by a toxicologist for evaluation of potentially hazardous materials. 2.1.2 art material or art material product--any raw or processed material, or manufactured product, marketed or represented by the producer or repackager as intended for and suitable for users as defined herein. 2.1.3 bioavailability--the extent that a substance can be absorbed in a biologically active form. 2.1.4 chronic adverse health effect(s)--a persistent toxic effect(s) that develops over time from a single, prolonged, or repeated exposure to a substance. This effect may result from exposure(s) to a substance that can, in humans, cause sterility, birth defects, harm to a developing fetus or to a nursing infant, cancer, allergenic sensitization, damage to the nervous system, or a persistent adverse effect to any other organ system.

DU P0502 97877
# D 4236
2.1.5 chronic health hazard(s) (hereafter referred to as
"chronic hazard")--a health risk to humans, resultant from
exposure to a substance that may cause a chronic adverse
health effect.
2.1.6 label--a display of written, printed, or graphic
matter upon the immediate container of any art material
product. When the product is unpackaged, or is not pack
aged in an immediate container intended or suitable for
delivery to users, the label can be a display of such matter
directly upon the article involved or upon a tag or other
suitable labeling device attached to the art material.
2.1.7 producer--the person or entity who manufactures,
processes, or imports an art material. .
2.1.8 repackager--the person or entity who obtains mate
rials from producers and without making changes in such
materials puts them in containers intended for sale as art
materials to users.
2.1.9 sensitizer--a substance known to cause, through an
allergic process, a chronic adverse health efFect which be
comes evident in a significant number of people on re-
exposure to the same substance.
2.1.10 toxic--applies to any substance that is likely to
produce personal injury or illness to humans through inges
tion, inhalation, or skin contact.
-
2.1.11 toxicologist--an individual who through .educa
tion, training, and experience has expertise in the field of
toxicology, as it relates to human exposure, and is either a
toxicologist or physician certified by a nationally recognized
certification board.
2.1.12 users--.artists or crafts people of any age. who
create, or recreate in a limited number! largely by hand,
works which may or may not have a practical use, but in
which aesthetic considerations are paramount.
3. Requirements
3.1 To conform to this voluntary practice the producer or repackager of art materials shall submit art material product formulation(s) or reformulation(s) to a toxicologist for re view, such review to be in accordance with Section 4 of this practice. The toxicologist shall be required to keep product formulation(s) confidential.
3.1.1 Unless otherwise agreed in writing by the producer or repackager, no one other than the toxicologist shall have access to the formulation(s); except that the toxicologist shall furnish a patient's physician, on a confidential basis, the information necessary to diagnose or treat cases of exposure or accidental ingestion.
3.2 To conform to this practice, the producer or repack ager, upon advice given by a toxicologist in accordance with Section 4 of this practice, shall adopt precautionary labeling in accordance with Section 5 of this practice and based upon generally accepted, well-established evidence that a compo nent substance(s) is known to cause chronic adverse health effects.
3.3 To conform to this practice, labeling shall be parallel to, conform to, and minimally include any labeling practices prescribed by U.S. federal and state statutes or regulations and shall not diminish the effect of required acute toxicity warnings.
3.4 To conform to this practice, the producer or repack ager shall supply a poison exposure management informa
tion source2 the generic formulation information required for dissemination to poison control centers or provide a 24-h cost-free telephone number to poison control centers.

. 4. Determination of Labeling
4.1 An art material is considered to have the potential Vr producing chronic adverse health effects if any customary oc reasonably foreseeable use can result in a chronic hazard
4.2 In making the determination a toxicologist(s) shall take into account the following:
4.2.1 Current chemical composition of the art material, supplied by an analytical laboratory or by an industrial chemist on behalf of a manufacturer or repackager.
4.2.2 Current generally accepted, well-established scien tific knowledge of the chronic toxic potential of each component and the total formulation.
4.2.3 Specific physical and chemical form of the aft material product, bioavailability, concentration, and the'1 amount of each potentially chronic toxic component fou.io in the formulation.
4.2.4 Reasonably foreseeable uses of the art matenJ product as determined by consultation with users and other, individuals who are experienced in use of the material(s)f such as teachers, or by market studies, unless such use information has previously been determined with respect tiTf the specific art material(s) under review.
4.2.5 Potential for known synergism and antagonism e , the various components of the formulation.
4.2.6 Potentially chronic adverse health effects of decom-"1 position or combustion products, if known, from any reasonably foreseeable use of the hazardous art material product.

FIG. 1 Top View of Holder for Contamination of Test Specimen in Seven-Day Exposure (Procedure B)
9.4.2 A test specimen is pushed into the positioning aid with its reference corner R as shown in Fig. 2. Edges A andB ofthe test specimen are brought into close contact with Lii s a and b of the positioning aid, the Contact B-b having priority. The test .specimen is then pressed against Part ' containing the silicone rubber ring by fastening the sere1. until the test specimen is in contact with Part V along all op us edges.
9.4.3 The test specimens are contaminated by applying i mL of the contaminant solution to the middle of the circle visible through Part f/.tThe holder shall be kept ill a horizontal position. If, in the case of highly hydrophobic surface materials, the contaminant does not immediately cover ihe test circle, the holder may be tilted to enforce sufficient spread of the liquid.
9.4.4 A small petri dish is placed over the test circle on t of Part U to prevent evaporation of the contaminant solution.
9.4.5 After seven-days contact time the contaminant solu tion is sucked offas completely as possible using a pipet. For this purpose it is necessary to tilt the holder. The holder is , then inverted. After removing the nuts and Part L, lift the test specimen vertically so that distribution of contaminant solution to uncontaminated parts of the test specimen is prevented.
9.4.6 To avoid evaporation effects immediately place the test specimen in a plastic bag. The whole procedure of removing the specimens from their holders and packaging them shall not take more than 12 min.
9.4.7 Position the contaminated specimens and scan as in 9.3.3.

Standard Practice tor Determining Coating Contractor Qualifications for Nuclear
Powered Electric Generation Facilities1
(Scope
1.1 This practice provides a criteria guide and procedural fethod to assist utility owners, architects, engineers, con-
actors, and other selection agencies in determining the uirall qualifications of a coating contractor to execute
ling work for the primary containment and other safetyated facilities of light-water nuclear power plants. 1.2 The qualification criteria and requirements address
essential basic capability of a contractor to execute uclear coating work. Obviously, the specific capability to nfute those requirements unique to a given project must
be carefully considered. The evaluation procedure gained in this practice is designed to be adaptive to this
iled final qualification process. Variation or simplificai ofthe practice is appropriate for non safety-related areas ^'nuclear power plants, fossil fueled facilities, and other [stria! projects. 1.3 The overall capability of a contractor to successfully cgute the varied and complex requirements of nuclear ting work is dependent upon competency in a variety of Ihtial categories. j! The nine evaluation categories described in Sections 3 ough 12 detail the specific data to be provided by the Stractor as essential to determining qualification status. In fpition, a tenth untitled category has been provided on the '"filiation work described in Section 12 for inclusion of per information pertinent to a specific project. .5 This standard does not purport to address the safety bblems associated with its use. It is the responsibility ofthe
of this standard to establish appropriate safety and %ahh practices and determine the applicability ofregulatory nations prior to use.

Standard Test Method for High-Shear Viscosity Using the id Cone/Plate Viscometer1'
This standard is issued under the fixed designation D 4287; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (0 indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers the determination of the
viscosity ofpaints, varnishes, and related products at a rate .of
shear of 12 000 s_I.
>
1.2 Paints and varnishes that dry very rapidly may not
give reproducible results with this test method. Measure
ments made at elevated temperatures may also give poor
precision due to loss of volatiles and to drying.
1.3 This standard may involve hazardous materials, oper
ations, and equipment. This standard does not purport to
address all ofthe safety problems associated with its use. It is
the responsibility of the user of this standard to establish
appropriate safety and health practices and determine the
applicability or regulatory limitations prior to use.

(0 to 1 Pa-s) or 0 to 5-P cone producing a rate of shear u 12 000 s~1. With higher viscosity materials, other cones (0 to 20 P, 0 to 40 P, 0 to 100 P) may be used on agreement between the producer and the user, but it should be notc_ that these give lower shear rates (~3000 s~`) not truly representative of application conditions. Other cone/plato viscometers may be used on agreement between the producer and the user as long as the same rate of shear is measured and it is approximately 12 000 s~'. However, results m, differ from those produced with an ICI cone/plate viscometer.
N ' I--The SI units for viscosity are pascal-seconds (Pa-s, 1 P- ,
= 10 P, 1 mPa-s= t cP).
6. Reagents and Materials
6.1 Water or AWw/rt--Water or a low viscosity solventil such as xylene or mineral spirits to be used for zeroing th^J instrument.
6.2 Mineral Oils--Three standard mineral oils v,,ii known viscosities (certified by an approved laboratory) lying between 10 and 90 % or full scale.4
3. Summary of Test Method
3.1 The material to be tested is placed between the cone and plate of an 1C1 cone/plate viscometer, then subjected to a high shear rate while the viscosity is determined.
4. Significance and Use
4.1 The viscosity value obtained by this test method gives information about the flow properties of the material under application conditions: brushing, spraying, electrostatic disk, or roll coating.
4.2 This test method is suitable for all paints and var nishes whether they are Newtonian in behavior or not. However, due to the narrow gap between the stationary and rotary parts of high-shear viscometers, this test method is more reproducible for paints having finer pigment disper sions as determined by Test Method D 1210.
5. Apparatus
5.1 ICICone/Plate Viscometer3 (see Fig. 1) with 0 to 10-P

2 Annual Book ofASTM Standards, Vol 06.01. 3 ICI cone/plale viscometers are available from BYK.-Gardner, Inc.. Gardner Laboratory. 2435 Linden Lane, Silver Spring, MD 20910 and from Research Equipment (London) Ltd., 64 Wellington Rd., Hampton Hill, Middlesex TW12 IJX, England.
7. Sampling
7.1 Take a representative sample of the product to be tested in accordance with Practice D 3925. If the sample has a tendency to settle or separate on standing, it must be stirred or shaken until homogenepus before a test specimen is taken from it. The specimen must be free of any foreign matter or air bubbles and its volume must be sufficient to cover the portion of the viscometer plate under the cone when thai3j latter is brought into contact with the plate.
8. Preparation of Apparatus
8.1 Zero the apparatus daily when in regular use, or otherwise before use, by following the procedure in Section 9. but using a low viscosity liquid. If the pointer does not indicate zero, it may be adjusted by means of a lever on the left-hand side of the upper part of the instrument housing, if the instrument cannot be zeroed, it should be returned to the supplier for adjustment.
8.2 Verify the calibration of the apparatus by following the procedure in Section 9, but using standard refined mineral oils having Newtonian characteristics and known viscosities.4 If the viscometer pointer reads the correct viscosity (or within 5 % of that value) with two or more oils whose viscosities bracket those of specimens to be tested, then the viscometer readings may be used as is. If the
4 Such oils arc available from The Cannon Instrument Co., P.O. Box 16, Sta College, PA 16801.

DUP050297900
FIG. 1 ICI Cone/Plate Viscometer
con leter readings do not give the correct viscosities for the then a calibration curve must be constructed by taking 1 iscometer readings for three oils and plotting measured |jsity versus specified (correct) viscosity for the oils. Jbquent measurements are corrected to true viscosities 8&h use of the curve. <`.3 Check the cones periodically for wear. Replace any
i that shows a definite flattening of the apex. Some users found it necessary to replace cones every year.
The determination must be made at a closely confed temperature of 25 0.3C unless otherwise agreed. In pr to check the temperature control, carry out the test as lifted in 9.1 with the standard refined mineral oil of the
est viscosity. Allow the viscometer to run with this oil for pin and determine whether the reading decreases. If the
-e is more than 10 %, the apparatus is unsuitable for ^determination of viscosities at high rates of shear in fedance with this test method.
tore 2--Multitemperature ICI cone/plate viscometers have heating, ghot cooling, capabilities. Therefore, runs with these viscometers at
; should only be done at room temperatures at or below 22"C to tfe that the plate temperature does not go above 25C. The
instruments that operate at 25"C only do have cooling capabilities and give better temperature control.
9. Procedure
9.1 With the cone in the down position, turn the instru ment on and allow it to warm up for at least 5 min. For a multitemperature instrument, set the dial at 25C or to an alternatively agreed upon temperature. Raise the cone to the up position. Transfer a suitable amount of the product to be tested to the plate, taking care to avoid the inclusion of air bubbles, and'again lower the cone to the down position. Wait for 30 s to allow the specimen to attain the agreed upon temperature.
9.2 Start the cone rotating and record the reading on the scale (Note 3) when the pointer becomes steady.
Non- 3--Whether the. reading gives a direct indication of the viscosity or not, depends on the cone and scale used.
N' 4--In some cases it is difficult to judge whether a constant
reading has been obtained. However, if the pointer does not become steady after 15 s, record the reading at 15 s and mention the lack of a constant reading in the test report. If highly accurate readings are required, make the readings below 90 % of the scale.
9.3 If the reading does not directly indicate the viscosity, multiply the reading by the appropriate conversion factor or use the appropriate calibration curve to obtain the viscosity.
9.4 Clean both the cone and the plate carefully, em ploying a cloth or tissue and a suitable solvent. Take care to remove all of the test material and cleaning solvent. Do not use cleaning utensils that may damage the apparatus. Metal cleaning tools must never be used.
9.5 Repeat the determination with a second specimen. If the two viscosity determinations differ by less than 7 %, calculate their mean and report as the high shear viscosity for the material. If they differ by more than 7 %, make a third determination. If no two readings are within 7 % of each other, then the material is not suitable for testing by this test method.
10. Report
,,
10.1 Report the following information: 10.1.1 Reference to this test method, 10.1.2 Type and identification of the product under test, 10.1.3 Type of cone used (0 to 5 P, 0 to 10 P, etc.), 10.1.4 Rate of shear at which the determination was made (in reciprocal seconds), 10.1.5 Temperature at which the determination was made,

within-laboratory coefficient of variation was found to be 2.2 %, at 40 df. The between-laboratory coefficient of
variation was found to be 6.9 % at 34 df. Based on these results, the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
11.1.1 Repeatability--Two test results, each the mean of two determinations obtained by the same operator, should be considered suspect if they differ by more than 6.3 % relative.
11.1.2 Reproducibility--Two results, each the mean of
two determinations, obtained by operators in different labo ratories should be considered suspect if they differ by mori than 19.9 % relative.

6.1.1 Substrate--Factors such as the texture, gloss, effec tive pH, porosity, chemical composition, and condition of the substrate will affect gloss, gloss uniformity, drying time, adhesion, and the flexibility of the dried film.
6.1.2 Environmental Conditions--Factors such as temper ature, humidity, air flow, and light conditions affect applica tion properties, film formation, drying time, and adhesion.
6.1.3 Storage--With aging and elevated temperatures, there may be a change in consistency and a separation of oil from, the paste paint.
6.2 Vehicles--Only vegetable drying oils shall be used in artists' oil paints. Resin-oil paints shall contain 90 weight % minimum ofvehicle solids, vegetable drying oil {see Note l), and 10 weight % maximum of vehicle solids replaced by gum or resin.
6.3 Pigments--Pigments to be used in oil paints shall be limited to those listed in the column labeled "Oil" and pigments to be used in resin-oil paints shall be limited to those listed in the column labeled "Resin-Oil" in Table 1. Their lightfastness rating shall be the numeral given in the same row. Those pigments listed as "not tested" shall not be used,
6.4 Driers'--Driers may be used in minimal amounts in paints that contain a pigment which has a retarding effect on the drying of oil. This is allowed so these paints can conform to the drying requirements of this specification.
6.5 Inerts--Minimal amounts of inert pigments may be used to produce desirable working qualities and consistency, to prevent separation, to develop chromatic properties, or to ensure the durability of the paint film.
6.6 Preparation of Sample--Empty the contents of a previously unopened container onto a glass slab and mix thoroughly with a spatula to a homogeneous sample.
6.7 Nonvolatile--The nonvolatile content shall not be less than 97 weight % for the oil paints and 90 weight % for the

particles and shall form a uniform film. The maximum content ofcoarse particles shall be 1 weight % as determined by Test Methods D 185.
6.9 Fineness of Dispersion--On a glass plate, using a spatula, mix the paint with an equal volume of linseed oil until homogeneous. If the paint is very thick, it may be necessary to add a minimum amount of mineral spirits or turpentine to make the paint sufficiently fluid to read the gage accurately. Determine the fineness of dispersion by Test Method D 1210. The maximum allowable grind reading is 1.5 mils (40 pm).
6.10 Consistency--The paste type of paint shall not flow or level when applied with a palette knife.
6.11 Drying--Using a film applicator with a 3-mil (75pm) clearance, make a uniform drawdown on a lacquersealed panel. At a relative humidity of 50 to 75 % and a temperature of 65 to 80F (18 to 27C), the dustfree drying time, as determined by Test Methods D 1640, shall not be more than ten days.
6.12 Tinting strength requirements will be included in this specification as appropriate tinting strength standards for individual pigments are established. Test Method D 387 may be used to determine the tinting strength of pigments or paints when all ingredients are known. Test Method D 4838 can be used to determine the relative tinting strength of chromatic paints containing a single pigment and the same vehicle but where other ingredients are unknown.
7. Quality Assurance for Artists' Alkyd Paints
7.1 Conditions Not Covered in This Specification that Affect Artists ' A llcyd Paints:
7.1.1 Substrate--See 6.1.1. 1A.2 Environmental Conditions--See 6.1.2. 7.1.3 Storage--With aging and elevated temperatures, there may be a change in consistency and possible solvent loss.

8.4.4 Preparation of Test Paints: 84.4.1 The pigment to be tested may be milled in a concentrated paste in a resin-oil vehicle. If a prepared resin-oil artists' paint of known composition is available, it may be used for this test. 84.4.2 Dilute the pigment paste or paint with the white given in 84.3.6 until the spectrophotometrie measurement of the dried film shows 35 to 45 % relative reflectance at the wavelength of maximum absorption for that pigment. The wavelength of maximum absorption is located at the point of lowest reflectance on the spectral curve between 420 and 620 nm. If using a tristimulus filter colorimeter, the lowest of the three filter readings is the region of maximum absorption and the dilution should be adjusted so that a reading of 35 to 45 % reflectance is obtained with this filter. The diffuse white
reference standard for all measurements should have an absolute reflectance between 97 and 100 %.
8.44.3 To obtain this reflectance, use the Kubelka-Munk Single Conslant Method described in Appendix X2 or use a trial and error method.
8.4.44 Make instrumental readings with the specular reflectance included to minimize the effect on readings of

any change in gloss and to minimize the effect of brush strokes.
8.4.4.5 Use an applicator with a 6-mils (150-pm) aperture to make a minimum size drawdown, 1 Vi by 1 Vi in. {40 by 40 mm), or other minimum size appropriate for the viewing area of the instrument used. Return ail recoverable paint to the batch to allow for repeat mixes and measurements.
8.4.4.6 For oil, alkyd, or resin-oii paint, an initial amount of 40 g of white paint is sufficient if specimens .are read wet and recoverable paint is returned to the batch. If the instrument provides a way to read wet paint behind glass, and specimens measured this way fall, within the accepted range when dry, this method can be used.
N
( 9--Another suggested method for reading oil paints while wet
is to cut from 0.013-mm thick kitchen plastic wrap (such as Saran wrap) the minimum size piece that will protect the instrument and then die-cut a hole in the proper location Vsin. (3.2 mm) smaller than the instrument aperture. Rubbing the plastic several times with a paper towel or tissue imparts sufficient static charge that the protective plastic adheres to the instrument enabling the operator to center the hole on the aperture. The wet oil paint drawdown can then be placed in position, taking earn not to disturb the plastic shield.
8.4.4.7 For the initial weights of white stated in 8.4,3.1, 8.4.3.4 and 8.4.3.6 the weighing must be accurate to 0.05 g.
8.4.5 Application ofPaints to Panels: 8.4.5.1 Prepare four specimen panels on appropriate sub strates for each pigment under test. Two are used in the first lightfastness tests and two are retained in subdued light, one for visual comparisons with the exposed panels and one in case a third test is needed to supplement results from the first two tests, as described in Procedure section Test Methods D 4303. 8.4.5.2 Apply the test paints by brush to the aluminum or posterboard exposure panels described in 8.2, depending on
whether exposure is to be under glass to the sun or to laboratory apparatus.
8.4.5.3 Using the No. 12 artists' flat bristle brush, brush the panels lengthwise, then crosswise, and again lengthwise, this time with a light touch to produce a film as smooth as possible. The mixing whites must be fluid enough t01 facilitate leveling, but not have excess vehicle that can affect the test. Do not use thinners. Oil-paint brushouts retain minor striations. Apply two coats to all specimen panels to achieve complete opacity.
8.4.5.4 Allow specimens to dry between coats as described in the Procedure section (Dry-Through or Dry-to-Handle Time) of Test Methods D 1640. After recoating, allow . specimens to dry hard, as described in the Procedure section >
(Dry-Hard Time) of Test Methods D 1640, before measuring j them prior to exposure. General guidelines for drying times 3
are one to two months to dry hard for oil and resin-oil paints; ^ three days between coats for alkyd paints; and five days after recoating.
8.4.5.5 When testing alkyd paints, prepare and expose a specimen of the mixing white along with the colored, | specimens diluted with this white. Since the purpose of these,! lightfastness tests is to evaluate any color change in the1? pigments, if the white yellows appreciably during exposure,adjust any color change between unexposed and exposeef colored specimens to eliminate the effect of this yellowing

X2. KUBELKA-MUNK SINGLE CONSTANT METHOD FOR PREPARING PAINT FILMS 40 5% REFLECTANCE
X2.1 Prepare a mixture of white and colorant in proporpns estimated to give a paint having a reflectance of 30 to
% at the wavelength of maximum absorption. Calculate he concentration of colorant in white in this batch.
Cc= wc/w,,+
here: = concentration of colorant, and
and Wc = weight of white and. colorant, respectively, used in the batch,
raw or brush a film of this paint over contrast paper at a ickness sufficient to give complete visual hiding. X2.1.1 After allowing the film to dry, measure the reflec-
ce of this film at the wavelength of maximum; absorption a spectrophotometer or, if using'a colorimeter, the
ectance with the filter that gives the lowest reading (Note .1). Calculate the Kubelka-Munk Single Constant Value this reflectance as follows:
(K/S)m = [1 - (Rm - 0.04)]2/2(Rm - 0.04)
here: fen. = Kubelka-Munk Value,
= reflectance measurement of the mixture, made with the specular component included expressed as a decimal value, and
= decimal value correction for surface reflectance.
jjfbTE X2.1--To speed drying, accelerated methods may be used. It is Itbnmended that water-based acrylic paints be warmed to 50 to 55C 'i h after I h of air drying before measuring the reflectance. Placing (drawdowns of oil paints near fluorescent lamps, for example in the Jpresccut light exposure racks described In Annex A1 of Test Methods 11303, will speed their drying time.
X2.1.2 Calculate the Kubelka-Munk absorption coeffiJt for unit concentration as follows:
: Kc='(K/S)JCc
e Kc = unit absorption coefficient. 2.2 Based on the results of the trial mixture, calculate
fconcentration of colorant in white required to give the
' ed 35 to 45 % reflectance at the wavelength of max'3m absorption as follows:
Cd = (K/S)w %fKc = 0.4500/K,
re Cd = concentration of colorant in white predicted to ,a paint with the desired 35 to 45 % reflectance value.
X2.3 Adjust the concentration of the trial `batch so that the concentration of colorant equals Cd. Determine the changes in colorant concentration, AC, as follows:
AC = Cd - C,
These changes are positive if the trial batch has a reflectance greater than 40 % and negative if the reflectance is less than 40 %. If AC is positive, add more colorant to the trial batch to bring the concentration of colorant to Cd. If AC is negative, add more white to bring the concentration of colorant to Cd. Because it may be necessary to add large amounts of white to correct for concentrations of colorant giving reflectance values far below 40 %, it is usually best to prepare a trial batch expected to give a AC value that is moderately positive or only slightly negative.
X2.3.1 For the case where AC is positive, determine the weight of colorant needed to prepare a second batch as follows:
&WC =WC- Cd(JKw + Hy/Cd - 1 x (L.F.)
where: A Wc - weight of colorant to be added to the trial batch to
obtain a corrected batch with a colorant concentra-
L.F. = loss factor = weight of paint from trial batch used to prepare the corrected batch/weight of paint pre pared as trial batch,
The loss factor, L.F., allows for paint removed to prepare drawdowns, loss by transfer to different containers, etc. This term may be neglected if losses are small compared to the batch size. The other terms are as defined in the previous sections of this appendix.
X2.3.2 For the case where AC is negative, the weight of white needed to prepare a corrected batch corresponds to,
A W,, =WC- Cd(l#w + y/Cd X (L.F.)
where A1FW = weight of white needed to adjust the colorant concentration in the batch to Cd. Other terms are as defined above or in previous sections of this appendix.
X2.4 Prepare a paint film from the adjusted batch. After drying, measure the reflectance at the wavelength of max imum absorption. If this value does not fall within 35 to 45 %, repeat X2.3 through X2.4, where Cd now becomes the Cc for the next batch correction. Normally only a single iteration is necessary and a second batch correction will not be needed.

Designation: D 4303 - 91
Standard Test Methods for
Lightfastness of Pigments Used in Artists' Paints1
rtf
This standard is issued under the fixed designation D 4303; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 Three test methods consisting of exposure to light (natural sunlight or simulated sunlight) filtered through glass are described as follows:
1.1.1 Test Method A--Exposure under glass to the sun, 1.1.2 Test Method B--Exposure to irradiance from artifi cial daylight fluorescent lamps, and 1.1.3 Test Method C--Exposure in xenon-arc lightfast ness apparatus. 1.2 These test methods are used to approximate the color change that can be expected over time in pigments used in artists' paints in normal indoor exposure.
N' 1--The color changes that result from accelerated exposure
may not duplicate the results of normal indoor exposure in a home or gallery. The relative resistance to change, however, can be established so pigments can be assigned to categories ofrelative lightfastness.
1.3 Lightfastness categories are established to which pig ments are assigned based on the color difference between specimens before and after exposure.
1.4 Color difference units are calculated by the CIE 1976 L*a*b* color difference equation.
1.5 these test methods apply to artists' oil, resin-oil, acrylic emulsion, alkyd, and watercolor paints.
1.6 This standard does not purport to address the safely problems, if any, associated with Us use. It is the responsi bility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

-3J1 Test Method A--Exposure Under Glass to Natural kt:
.1.1 Mount the specimens on an open type rack and : at 45 angle to the vertical to a total radiation dose of MJ/m2 in accordance with Practice G 24. !i.2 For tests in southern Florida expose panels during "tenths of October through May.

mm) from the plane of the lamps. 7.3.2.2 Unless specified otherwise, expose the specimens
to a repeating cycle of 8 h light followed by 4 h dark until the specimen has been exposed to a total radiant energy dose of 1260 MJ/m2. Rotate the specimen panels two positions to the right after each 100 MJ/m2 dose. This test method takes approximately nihe months to complete.
73.2.3 Maintain the ambient room temperature at 24 3C and prevent the test chamber from exceeding room temperature by more than 6C. 73.2.4 Monitor irradiance at the specimen location for
total radiation for each rotation period. Measure radiation 1 h after the lamps are turned on and at the end of the period. The mean of these readings in joules per square centimetre (J/cm2) per hour multiplied by the number of hours of radiation gives the J/cm2 for that period.
7,33 Test Method C--Exposure to Simulated Daylight (Xenon-Arc Type):
73.3.1 Mount specimens in unbacked holders avoiding positions that place specimens at the extreme top or bottom of the specimen rack.
7.33.2 Unless specified otherwise, expose specimens con tinuously to a total radiant dose of 1260 MJ/m2 in accord ance with Practice G 26, Test Method C. Maintain the relative humidity in the test chamber at 55 5 % and a black panel temperature of 63 2C.
N' 2--When mutually agreed upon, an alternative dark cycle may
be employed in accordance with Test Method D of Practice G 26, optical filter combination (c), and test conditions reported. It has been found that Alizarin Crimson, and possibly other pigments, are affected
by a light -and dark cycle, owing to the oxidation-reduction effect of titanium dioxide changing valence with the changes from light to dark and vice versa, characteristic of daylight and indoor light.
733.3 When continuously monitoring irradiance with a
narrow bandpass radiometer, the dosage at the monitored
wavelength may be calculated knowing the total and spectral
irradiance from the lamp operating at a specified wattage,
usingtheequation:
*
QcX=3.6(103)fs, '

where: A = wavelength bandpass expressed in nanometres,
nm, Qe = radiometric symbol for radiant exposure, J/m2, 3.6 (103) = a constant, s/h, for converting hours to seconds, t = time expressed in hours, h, and Ec = radiometric symbol for irradiance, W/m2.
N' 3--1 W = 1 J/s. N' 4--An example is given in Appendix XI.
7.4 Measure test specimens immediately after exposure with specular reflection included in the measurement and record.
7.5 Calculate the color difference between the specimen before exposure and after exposure in accordance with the CIE 1976 L*a*b* color difference equation in Test Method D 2244. State the color change in total color difference units (4E*ab>.
7.6 Visually check the exposed specimen against the unexposed specimen of the same paint kept in subdued light, in order to verify that the color difference stated in AE*ab units agrees with visual assessment. Make this check also

following any subsequent exposures. 7.7 Since all test methods can produce aberrant results in
pigments that are sensitive to some aspect ofa particular type of exposure, assign pigments to lightfastness categories based on results from a minimum of two of the methods described in 7.3.1 through 7.3.3. Four exposures arc preferred but there may be fewer in many cases using the following procedure:
7.7.1 Unless specified otherwise, expose one specimen inland outdoors under glass to sunlight in southern Florida below 27" latitude following Test Method A and expose the second specimen indoors to simulated daylight following either Test Method B or Test Method C. Place pigment in the appropriate category if both tests indicate the same category and neither result is within 0.5 AE*ab of the borderline between categories.
7.7.2 If the results, from the first two tests place the pigment in different lightfastness categories, or ifeither of the test results fall within 0.5 AE*ab of the dividing line between two categories, either assign the pigment to the poorer of the two categories involved or for a more accurate rating, proceed with the third exposure. The third exposure may use either the method not used in the two previous exposures, or may repeat the exposure which gave the poorer result, providing the two- test results are within 4 AE*ab of one another. To guard against accepting an aberrant test result, if there is more than 4 AE*ab difference between the first two test results, use the method not employed in the first two tests for the third exposure.
7.7.3 Calculate the mean of the color differences from the three exposures to determine the appropriate lightfastness category unless one of them differs from the nearest test result by more than 4 AE*ab, or the mean is within 0.5 AE*ab of the dividing line between categories. In these cases make a fourth exposure.
7.7.4 For the fourth exposure use the method not previ ously employed, or if all three methods have been used, for the fourth exposure repeat the method with poorest result, unless the results from that method differs from the nearest other test result by more than 4 AE*ab. In this case, discard this one test result. Calculate the mean of the test results from the four exposures, or three exposures if one has been discarded, to determine the' lightfastness category.
8. Interpretation of Results
8.1 Lightfastness I--Assign pigments that exhibit a mean color change of 4 or less AE*ab to Lightfastness Category I.
8.2 Lightfastness II--Assign pigments that exhibit a mean color change of more than 4.0 but not more than 8.0 AE*ab to Lightfastness Category 0.
8.3 Lightfastness III--Assign pigments that exhibit a
mean color change of more than 8.0 but not more than 16 q to Lightfastness Category III.
8.4 Since some exposed specimens have lost all color at a color difference of 20 units, additional categories are not appropriate for artists' paints.

The air from the blower passes immediately through an air filter O and, after passing through the specimen exposure area, is vented out through the top of the cabinet. The blower furnishes the filtered air draft that keeps the temperature in the cabi net to within 6'C of the ambient
temperature of the room. The small 6C temperature rise is sufficient to limit the humidity in the cabinet to about 60 % relative humidity even when the general humidity is vefy high. Install a thermometer in the top of the cabinet near the vent and away from any direct illumination from the lights
A1.5 If preferred, a smaller open apparatus holding a single bank of four Verilux daylight fluorescent lamps may be constructed as shown in Fig. A 1.2. A small fan blowing through the unit from one end furnishes the air draft, feu. otherwise the apparatus must have the same distance be tween lamps and specimens and the same monitoring equipment described in A4.2 and A1.3.

APPENDIX
(Nonmandatory Information)
XI. EXAMPLE OF DOSAGE CALCULATION
X1.1 The calculation is as follows:
Given: Total dose, QT = 1260 MJ/m2 Assume: Total irradiance, , = 1000 W/m2
Spectral irradiance, Ex -- 0.5 W/m2
(XI.1)
where A = wavelength of measured spectral irradiance.
0T = 3,6 (103) t Et
1260 (106) = 3.6 (103) t (1000)
so t = 1260 (106}/3.6 (10s) = 350 h
Thus, if the total irradiance from an energy source remains constant at 1 kW/m2, 350 h are required to provide a total dose of 1260 MJ/rn2.
XI.2 If the spectral irradiance at wavelength, A, remains
constant, then the spectral irradiation, Qx, or the control dosage, is calculated by the equation, as follows:
2 = 3.6 (103) t E,, 2 = 3.6 (103) 350 (0.5), 2a = 630 (103) J/m2, or 2a = 630 kJ/m2.
X1.3 The time required to obtain this dosage may be varied by varying the spectral irradiance. For Ex -- 0.25, the exposure time will double to 700 h.
XI.4 If the fluorescent lamp system requires nine months to accumulate 1260 MJ/m2 when the lamps operate two thirds of the time, about 4380 h, then the mean irradiance from the lamps would be:
Ey = 1260 (106)/3.6 (103) 4.38 (I03) = 75.1 W/m2 (X1.3)

6. Sampling
6.1 Using standard sampling techniques, secure a repre sentative sample from the lot or batch being tested, in accordance with Practices D 3925 or E 300.
7. Test Specimen
7.1 If the sample is supplied in a friction top quart can that is at least 85 % full, use the can and material as supplied.
7.2 If not, place the material to be tested into the quart can, filling it to at least 85 % and allowing enough ullage for expansion of the material without displacement of the cover. Tightly close the can so that no vapor escapes.
N' --The can is considered 85 % filled when the material level is
no more than !h in. (20 mm) below the lip of the can.
8. Procedure
8.1 Place the can with the material in an oven maintained at 100 5F (38 3"C). Allow the contents of the can to come to temperature equilibrium (18 to 24 h).
8.2 Place the tripod or ring stand on a level surface. 8.3 After the material has come to temperature equilib rium take the can from the oven and immediately remove the lid. With the ruler, measure the distance from the surface of the material to the top of the lip of the can and record. 8.4 Invert the can onto the tripod or ring stand in a vertical position over the tared watchglass. If a skin has formed on the surface of the material, break the skin prior to inverting the can. Determine the flow of the specimen out of the can at the end of 3 min, by measuring the vertical distance the material has flowed from the lip ofthe can to the tip of the specimen. 8.5 Add the distance from the surface of the material to the top of the lip ofthe can (8.3) to the distance the material has flowed below the lip of the can (8.4). 8.6 If there is an appreciable flow from the can before the 3 min are up, that is, more than 2 in. (50 mm), immediately stop the test and place the can in an upright position. 8.7 Collect any free-flowing material onto the tared watchglass and weigh.
9. Interpretation of Results
9.1 A material that flows a total of 2 in. (50 mm) or less within 3 min is considered a solid. Otherwise, it is considered a liquid.
9.2 If 1 g or more of liquid is collected on the watchglass, the viscous specimen is considered a liquid regardless of its flow characteristics.

high operating speeds and with fluids that produce long filaments.
3. Summary of Test Method
3.1 A thin film of the test printing ink or vehicle is applied to the three-roller distribution system of the Inkometer, which operates at speeds comparable to those on production printing presses. Measurement of the frictional torque in duced by drag forces in the splitting film provides an arbitrary value for apparent tack. On mechanical model?, the torque is determined with a manually balanced lever arm, a direct-reading attachment, or a recorder; on electronic models, with a digital readout, recorder, or printer. Readings are in units of gram-meters (g-m).
3.2 The procedure in this test method is designed to give a single value for apparent tack at a specific set of Inkometer conditions. Typical conditions are as follows: a cooling water temperature of 90"F (32.2C); a volume of 1.32 mL (film thickness 12.3 pm) of the test printing ink or vehicle applied to the rollers; an operating speed of 400 r/min for vehicles, 800 r/min for sheet-fed offset inks, and 1200 r/min for web-fed inks;- and a reading after 1 min of operation. Alternative conditions may be used by agreement between the supplier and the customer.
3.3 Instructions are also given for calibration of the Inkometer and for minimizing effects of interactions among the rollers, test fluids, and wash-up solvents.
4. Significance and Use
4.1- Tack of printing inks controls their high-speed transfer properties, as manifested by throughput in roll milling, picking of paper during printing, and wet trapping in multicolor printing. Although an apparent tack measure ment does not completely predict the transfer performance of an ink or a vehicle, it provides a meaningful parameter for quality control, development, and research.
4.2 A given Inkometer will produce repeatable results on a day-to-day basis only if proper attention is paid to calibration and maintenance procedures and to control of experimental variables referred to in 2.1.1.1.
4.3 Two or more Inkometers may not produce identical apparent tack readings, but if each gives repeatable results, they may be mathematically correlated.
N ' I --Besides the Inkometer, a number of three-roller tackmeters
are available which differ in design features such as roller weight, geometry, and composition. It cannot be presumed that test results from these other types of tackmeters will either agree or correlate with those from the Inkometer.

D 4361
5. Interferences
5.1 Inkometer Squeal--A high pitched whine or squeal may be noted when running high tack fluids or at high rotating speeds, or both. Inkometer squeal may result in instability of the balance beam or direct reading attachment of the mechanical Inkometer or fluctuation of the digital readout of the electronic Inkometer, making definite read ings difficult.
6. Apparatus
6.1 Inkometer2--one of five models differing in available speeds and type of readout as follows:
6.1.1 Mechanical Models B-453, C-453, or MBC, oper ating at fixed speeds of 400, 800 and 1200 r/min on the B-45; 400, 1200, and 2000 r/min on the C-45; and 400, 800, 1200 and 2000 r/min on the MBC. A direct reading attachment2 or a recorder2 is recommended to supplement the manually operated balance beam.
6.1.2 Electronic Models 10I-A3 or 101-8, operating at variable speeds ranging from 100 to 2000 r/min on the 101-A and from 100 to 3000 r/min on the 101-B. A recorder2 or printer2, or both, are recommended to supple ment the digital readout.
N!"' 2--To convert to units of linear.speed, multiply Inkometer
revolutions per minute by 0.785 to obtain feet per minute or by 0.004 to obtain metres per second.
6.2 Inkometer Rollers,2 of suitable composition, prefer ably one set for each major system to be evaluated (see 10.3.1.) A set consists ofa top (measuring) roller 3'/s in..(79 mm) in diameter and 61/s in. (155 mm) in length, and a vibrator 2.0 in. (51 mrh) in diameter and 1'U in. (184 mm) in length. Together with the fixed brass roller, the total surface area of the distribution system is 166 in.2 (0.107 m2).- The measuring roller weighs 9.2 lb (4.2 kg) on mechanical models and 9.6 lb (4.4 kg) on electronic models.
6.3 Ink Pipet, consisting of a metal cylinder and a metal or' TFE-fluorocarbon plunger. Suitable pipets include the fixed-volume Inkometer pipe,2 1.32-mL capacity; and vari able volume micropipets,'' 2-mL capacity, accurate to 0.01 mL.
6.4 Stopwatch or Timer, accurate to 1 s. 6.5 Ink Knife, small, free from nicks and rough edges. 6.6 Manufacturer's Calibration Apparatus,2 for the spe cific model Inkometer.
7. Reagents and Materials
7.1 Wash-Up Solvent, compatible with the test system, fast evaporating, and having minimal effect on the rollers; it should be acceptable environmentally. Hydrocarbon sol vents with an initial boiling range of 250 to 350F (120 to 177"C), a final boiling range of 300 to 400'F (150 to 205C), a Kauri-Butanol value of 30 to 40 and less than I % benzene content are appropriate for many sheet-fed and heat-set

7.2 Rags or Wipers, clean, soft, absorbent, lint-free. 7.3 Manufacturer's Current Manual?-, for the specific model Inkometer.
8. Hazards
8.1 Never let an ink or a vehicle dry completely on the rollers of the Inkometer.
8.2 Caution--Never turn the ZERO button except during the calibration process (see 12.2.1).
8.3 Take care not to damage the rollers during the cleaning process or by leaving them in contact when the instrument is not in use.
8.4 Do not disengage the balance beam of the mecham,a, Inkometer except when taking a reading.
9. Sampling and Test Specimen
9.1 Carefully select a sample that is free of skin and other contamination and representative of the, lot being evaluated A minimum of 3 to 4 mL is sufficient for two specimens Transfer to a clean container, protect with skin paper, ckr-c and seal.
9.2 When ready to make a run (see 12.3), fill the ink pipet as follows: Transfer 1.5 to 2 mL of sample to a clean glass plate; close and reseal the container. Gently work up with at ink knife but do not aerate. Fill the ink pipet with 1.32 mL of the worked sample (or with a smaller volume (0.5 to 1.0 mL) if a thinner film thickness is desired). Use the ink knife to force the specimen into the cylinder while slowly pulm G back the ram. Wipe excess material off the top of the pi vi
N#$' 3--A specimen volume of J.32 mL. divided by:the roller
surface area of 0.107 m2, gives an initial film thickness of 12.3 pm when distributed uniformly on the roller system of the Inkometer. Howi the occurrence of appreciable flying or misting will result in \oiv t specimen from the rollers. Hence, operating film thickness is unknown.
10. Preparation and Conditioning of the Inkometer
10.1 Locate the Inkometer on a sturdy bench in % draft-free temperature-controlled environment, preferably 73.5 3.5F (23 2C). Humidity, control is necessary for test samples that arc moisture-sensitive or prone to mistingy
10.2 Set the Inkometer water bath at 90,0 + 0.2"F (32.2 x , O.rC). All tests are to be run at this temperature. (See aK Annex A1.3.)
10.3 Prior to use, ascertain the nature of the test sample for the following reasons:
10.3.1 Roller conditioning--Use only an Inkometer having rollers well broken in for the type of test system. The break-in procedure is given in Annex A 1.2. A separate set of broken-in rollers is mandatory for radiation curing systems. The necessity for separate sets of broken-in rollers, or for extensive reconditioning when switching among different types of conventional test systems shall be determined in each laboratory.
10.3.2 Operating speed--Vehicles are most commonly run at 400 r/min, alternatively at 800 r/min; sheet-fed inks at 800 r/min, alternatively at 400 or 1200 r/min; and web-fed inks at 1200 r/min, alternatively at 800 or 2000 r/min. (The conversion to linear speed is given in Note 2.)

. lowest available speed for about 30 min. 1.2 Make a conditioning run with a specimen repre"ve of the system to be evaluated. Apply 1 to 1.5 mL of k or vehicle, and run for 5 to 10 min at the specified eed (see 10.3.2). Clean up as directed in Section 13.
Iibration of the Inkometer
1 Calibrate the Inkometer before initial use and pen ally as needed. First, conduct the necessary steps in 10.3 10.4. .2 Using the manufacturer's calibration apparatus, w the directions in the instrument manual. ,2.1 Mechanical Models--Zero and calibrate the bal-
beam (and direct reading attachment or recorder, if are to be used) at the test speed specified in 10.3.2. jH.2.2 Electronic Metals--Zero and calibrate the digital out (and recorder, if it is to be used) at 1000 r/min. n calibration is completed, check the dry reading at the |hed test speed (see 10.3.2).
O%' 4--The Inkometer can be calibrated at only one speed.
1f.3 After each calibration or at regular periods, .make a fun with a standard ink or vehicle. (See Annex A 1.5.)
/Procedure for Tack Evaluation
,
0.1 If necessary, make preparations as in 10.3 and 10.4, calibrate the Inkometer as in Section 11. If using an tronic model, make sure the motor is preset to the test d specified in 10.3.2 and the drive is in the LOW mode. 2 Engage the rollers and run at the specified test speed, e .dry reading differs from zero by more than 0.5 g-m,
ban the rollers in accordance with 13.1 or recalibrate in Urdance with Section 11. 2.2.1 The dry reading on a properly calibrated instrunt is directly related to the condition of the top (mea' g) roller; therefore, large deviations from zero are
ect. Usual causes are inadequate cleaning, residual pie or wash-up solvent, or mechanical damage. Do not
'the ZERO button, as doing so will shift the scale. Do not
fnpt to compensate by subtracting the dry reading from
test reading. Always reclean or recalibrate. Should large rations from zero persist, contact the manufacturer about possibility of serious mechanical damage. 2.3Turn the Inkometer off, disengage the rollers, and fill pipet as in 9.2. Transfer its contents to the vibrator in a
s of thin ribbons around the middle 5 in. (125 mm) of roller. Wipe any specimen remaining in the pipet onto a
place on the same roller. Reengage the rollers. 2.4 Distribute the specimen on the rollers and start the
as follows: 12.4.1 Mechanical Models C-46 and B-45: 12.4.1.1 Manually turn the motor coupling about ten Volutions, or until the specimen appears evenly distributed ong the three rollers. 12.4.1.2 Set the gears at 400 r/min, start the motor and
stopwatch simultaneously, and let the ink distribute for s. Stop the motor but not the stopwatch.
12.4.1.3 Quickly switch the gears to the test speed (spec
ified in 10.3.2) and immediately restart the motor, noting the
time on the stopwatch.
12.4.2 Mechanical Model MBC:
12.4.2.1 Place the fingertips against the sides of the brass
roller and manually turn about ten revolutions, or until the
specimen appears evenly distributed among the three rollers.
Do not touch the surface of the rollers.
12.4.2.2 Place the speed control switch at the 150 r/min
position. Simultaneously depress the power switch on the
Inkometer and start the stopwatch. Let the ink distribute for
15 s.
12.4.2.3 Quickly reposition the speed control switch to
the test speed, noting the time on the stopwatch.
12.4.3 Electronic Models:
12.4.3.1 Place the fingertips'against the sides of the brass
roller and manually turn about ten revolutions, or until the
specimen appears evenly distributed among the three rollers.
Do not touch the surface of the rollers.
12.4.3.2 Depress the DRIVE button and simultaneously.
activate the stopwatch. Let the ink distribute for 15 s at the
automatic LOW speed of 150 r/min.
12.4.3.3 Quickly switch to the test speed (preset in 12.1)
by depressing the HIGH/LOW button again, noting the time
on the stopwatch.
12.5 After 60 s of running at the test speed, record the
apparent tack of the test specimen from the balance beam
(see Annex A1.4); direct-reading attachment, or the recorder
of a mechanical Inkometer or thb digital readout, recorder,
or printer of an electronic Inkometer.
12.6 Optional--Rather than restrict the test to a single
apparent tack determination, valuable information riiay, in
some cases, be gained by continuing the run, taking readings
at uniform time intervals (facilitated by the use of a recorder)
until the apparent tack begins to decrease. Alternatively, the
Inkometer speed may be varied stepwise and a tack reading
taken after a specified time at each speed.
12.7 After the run, stop the Inkometer and clean up, as
directed in Section 13.
:
12.8. Make a replicate test with another specimen of the
same sample by repeating 12.2 through 12.6. The two tests
should agree within the repeatability given in Table 1.
13. Wash-up Procedure
13.1 With the Inkometer running at the lowest speed, apply a small amount of wash-up solvent to the rollers. Remove most of the specimen from the system by placing pads of the clean, soft, absorbent lint-free rags or wipers firmly against the bottom of the brass roller. Repeat this procedure with additional solvent and pads until the rollers are free from ink or vehicle. If any material remains on the edges of the composition rollers, remove very gently with a solvent-moistened rag.
N&'' 5: Caution--Remove material directly from the measuring or vibrator rollers with extreme care. Undue pressure will cause uneven wear of the rollers and may place significant strain on the torsion bar of the electronic Inkometer. Use extreme care to ensure that the cleaning pad does not go through the roller nip; otherwise, serious mechanical problems may result and recalibration will be essential.
13.2 Dry the rollers thoroughly by running them in

inks with a broad range in tack were measured for apparent tack ten times at I min and 5 min on mechanical Inkometers in six laboratories and on electronic Inkometers in eight laboratories.
15.1.2 In a separate interlaboratory study6 of this test method, four quick-set vehicles and four heat-set vehicles with a broad range in tack were measured in duplicate on two different days at 1 min and 5 min at 400 r/min on electronic Inkometers in six laboratories. The four quick-s t vehicles were also measured at 1 min at 800 r/min.
15.1.3 The within-laboratory/ and between-Iaboratoi v standard deviations are shown in Tabic 1. Biased on these' standard deviations the following criteria should be used for; judging the acceptability of results at the 95 % confidence level:
15.1.3.1 Repeatability--Two individual results obtained1 by the same operator should be considered suspect if they differ by more than the values given in Table 1.
15.1.3.2 Reproducibility--Two results, each the mean of two readings, obtained by operators in different laboratones should be considered suspect if they differ by more than (he values given in Table l.
15.2 Bias--Bias cannot be determined as there are no known methods for measuring actual splitting forces. The-, are indications that apparent tack measurements from the Inkometer correlate best with transfer performance when a series of test samples is based on the same vehicle chemistry

Al. INFORMATION CONCERNING INKOMETERS
.1 Routine Maintenance of the Inkometer
A1.1.! Routine maintenance of the Inkometer is ex|femely important to the mechanical integrity of the instru ment; see the manufacturer's current instruction manual for
specific model. A 1.1.2 The measuring and vibrator rollers may acquire a
;ed or shiny appearance with use, depending on the test Item and the wash-up solvent. This glaze may result in a
lificant change in the apparent tack reading of an ink or iicle. The glaze may be removed by extra cleaning with a mg solvent such as acetone. If not, the composition rollers should be replaced.

4,1.2.1 New Inkometer measuring and vibrator rollers
selectively absorb certain components of some test
gems, up to a saturation point, at which point they may be
to be broken in. Until this selective absorption is
plete, tack determinations made with these rollers may
|be repeatable. Break in new rollers using the following
ibedure:

Al.:.2.1.1 Place the rollers on jthe Inkometer. Choose as :ak-in samples those representative of the system that will

pie break-in sample for extended periods oftime, wash-up
8Si the solvent to be used, reapply the sample, run,
h-up, etc.

'
HJl.2.1.2 Break-in time may vary from several hours to eral days. Reproducible apparent tack readings on fidard samples (see Al.5.1), over a period of several days, . ieate that the rolls are broken in; they may then be put
routine use. Al .2.2 A major change in ink systems may adversely |qt the Inkometer rollers. When a set of rollers has been '
for one system, and it is to be.used for another, use this i;e break-in procedure. The rollers may then no longer be itable for the original system.
|}3 Temperature Control of the Inkometer Water Bath
U.3.1 Extremely precise temperature control of the kometer water bath is essential for repeatable apparent
: readings.
A 1.3.2 The thermometer furnished with the mechanical Inkometer, and the temperature gage of the electronic Iiikometer are accurate to 0.5F (0.3C).
A1.3.2.1 It may be advantageous to use a Bomb Calorim eter Thermometer ASTM 56F, 66.0 to 95.00T, with divi sions of 0.05F, or ASTM 56C, 19.00 to 35.00"C, with divisions of0.02C, in the Inkometer water bath. Position the thermometer in such a manner that the bottom of the mercury bulb is in line with the return inlet from the brass roller.
Al.3.3 The temperature-control system of the Inkometer is capable of controlling the temperature inside the brass roller within 0.5F (0.3C). ,
Al ,3.3.1 It may be advantageous, particularly, if high-tack samples are run for .extended periods of time, or if the Inkometer is in constant use, to augment the temperature control system with a cold-water cooling coil. A coiled length of '/4-in. (6.3-mm) outside-diameter copper tubing may be placed in the water-bath reservoir, in the flow area away from the thermometer. The coil is connected to a cold-water tap with a pressure regulator and emptied into a sink or drain,
A1.-1 Reading the Mechanical Inkometer Balance-Beam
A1.4.1 In order to take a reading from the balance beam of a mechanical Inkometer, disengage the beam and move the sliding weight until the beam is continuously in balance. Read the scale at the left of the sliding weight, using the scale alignment cutout to facilitate reading.
A 1.4.2 Minimization of parallax is necessary for repeatable apparent tack readings. It may be useful to mount a small reflective surface on the beam stop behind the zero indicator and the balance b^am. The zero indicator and the zero line on the balance beam are aligned in the reflective surface when an apparent tack reading is being taken.
A 1.4.3 Reengage the balance beam immediately after taking the reading.
A1.5 Standard Test Samples
Al.5.1 It may be useful to designate one or more inks or vehicles as standards. Samples that are stable and have a good shelf life without a change in apparent tack reading (for example, tack rated or tack graded) are appropriate. Daily apparent tack readings on these samples ensures that the Inkometer is in calibration and serves as a check on repeatability.

Standard Test Methods for Hardness of Organic Coatings by Pendulum Damping Tests1
This standard is issued under the fixed designation D 4366; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 These test methods cover the use of pendulum damping testers in the determination of hardness of organic coatings that have been applied to acceptably plane rigid surfaces, such as a metal or glass panel.
1.2 Two test methods based on different pendulum types are covered as follows:
1.2.1 Test Method A--Konig Pendulum Hardness Test 1.2.2 Test Method B--Persoz Pendulum Hardness Test 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility ofthe user of this standard to establish appro priate safety and health practices and determine the applica bility ofregulatory limitations prior to use.

3. Terminology
3.1 Descriptions of Terms Specific to This Standard: 3.1.1 Konig hardness--time in seconds for the swing amplitude of the Konig pendulum to decrease from 6 to 3". 3.1.2 Persoz hardness--time in seconds for the swing amplitude of the Persoz pendulum to decrease from 12 to 4.
4. Summary of Test Methods
4.1 A pendulum resting on a coating surface is set into oscillation (rocking) and the time for the oscillation ampli tude to decrease by a specified amount measured. The shorter the damping time, the lower the hardness.
5. Significance and Use
5.1 The pendulum damping test has been found to have
good sensitivity in detecting differences in coating hardness, where hardness is defined as resistance to deformation.
5.2 The two procedures given in these test methods embody the principle that the amplitude of oscillation of a pendulum touching a surface decreases more rapidly the softer the surface. However, these test methods differ in respect to pendulum dimensions, and period and amplitude of oscillation.
5.3 In general, the damping time of the Konig pendulum is approximately half that of the Persoz pendulum.
5.4 The Persoz pendulum has a greater degree of discrim ination than the Konig for measuring the hardness of soft coatings, but it may not be as suitable for testing hard, slippery films because of its tendency to skid on surfaces with! a low coefficient of friction.
5.5 The interaction between the pendulum and the paint film is complex, it depends on both elastic and viscoelastic - i properties, and it may not be possible to establish a precise relationship between the two types of pendulum tests.

7. Sampling and Sample Preparation
7.1 The sample should be obtained while the electrocoat bath is under proper circulation such that a uniform material is obtained. In case of an ultrafiltrate, the material should be thoroughly mixed or stirred prior to sampling to assure uniformity.
7.2 After sampling and prior to removing a test specimen, it is mandatory that the samples be shaken or stirred until they are homogeneous and free of any settled material. This is particularly important if there is a delay between sampling the bath and performing the test. The absence of settled material can be ascertained visually (in a transparent con tainer) or by inserting a spatula, scraping the bottom of the container, and making sure that there is no settled matter. The shaking or stirring of the samples should be carried out up to the moment of taking a specimen; this Point is Very Important.

8.2 Add approximately 40 mL of THF/PG 80/20 mixture to the specimens in the beakers and cover, preferably with aluminum foil, to minimize evaporation of the solvent mixture.
N./' I--In cases where the recommended THF/PG 80/20 mixture
causes precipitation of the material, substitute the same amount of an appropriate solvent or solvent mixture to a new specimen The formation of a precipitate during the titration might foul the electrode system and mask potentiometric changes. Other solvents suitable for dilution are acetone, dimethylformamide, toluene, or methafiol. Any other solvent or solvent mixture that does no: cause the formation of a precipitate throughout the titration is suitable. In certain instances it may be necessary to run a titration blank and to make the appropriate corrections for the solvent.
8.3 Titrate both specimens with 0.1 N HC1 s'olution using the automatic potentiometric titrator until aii end point "break" is reached.4 Add approximately 5 mL of additional titrant to complete the curve.

3. Summary of Test Method
3.1 A specimen is placed in a conductivity cell, or conversely a conductivity cell is placed in an eiectrocoat material, and the cell is connected to a conductivity bridge. The electrical conductivity is read directly off the meter of the bridge as the instantaneous peak reading.
4. Significance and Use
4.1 The conductivity of eiectrocoat baths results from the presence of ionic species in the bath, which come from the vehicle and from the presence of impurities present as ionizable acids, bases, salts, or combinations of these. The presence of excessive amounts of ionic impurities is detri mental to the application and performance properties of electrocoating paints. The test is suitable for use in research, production, quality control and eiectrocoat bath process control.
4.2 Other related methods for determining the electrical conductivity of water are described in Test Methods D 1125.
5. Apparatus 5.1 Conductivity Bridge- -Battery, or AC/DC line-oper-
ated, capable of. providing a conductivity reading almost instantaneously.
5.2 Conductivity Cell--Dip or fill type, cell constant of 1.0.

5.3 Thermometer--Any type capable of 0.5C accuracy with a --2 to 32C range.
5.4 Measuring Vessel--Any suitable cylindrical contain.,, capable of holding sufficient eiectrocoat sample to cover th electrodes of the conductivity cell, and allowing at least 25 mm between the conductivity cell and the sides of the vessel
6. Reagents and Materials
6.1 Purity of Water--References to water shall be understood to mean water conforming to Type II of Specification D 1193.
6.2 Cleaning Solvent--An appropriate solvent for the eiectrocoat material under measurement.
7. Sampling and Sample Preparation
7.1 The sample should be obtained while the eiectrocoat bath is under proper circulation so that a uniform sample obtained. In the case of an ultrafiltrate, the material should be thoroughly mixed or stirred prior to sampling to ensure uniformity.
7.2 After sampling and prior to removing a test specimen, it is mandatory that the samples be shaken or stirred until they are homogeneous and free of any settled material. This is particularly important if there is a delay between sampling," the bath and performing the test on the bath materials. lh;1 absence of settled material can be ascertained visually ( transparent container) or by inserting a spatula, scraping the ` bottom of the container and making sure that there is i ( settled matter. Shake or stir the sample until specimens are , taken for measurement; THIS POINT IS VERY IMPORTANT.
8. Procedure
8.1 Calibrate the conductivity cell prior to use followk the manufacturer's instructions.
8.2 Rinse the measuring container several times with portions of the eiectrocoat material under test.
8.3 Take a representative portion of the eiectrocoat bath or permeate sample and place it in the measuring contain * Stir the specimen thoroughly to keep it from settling.
8.4 Adjust the temperature of the specimen to 25 0.5"( This is very important, since temperature differences cause disagreements in results and are a major source of error in these measurements.
8.5 Immerse the cell in the specimen, and move the cel1 up and down several times to displace any air bubbles from inside the cell. Hold the cell in a slightly inclined position in the center of the container with the vents at the top ofthe cell housing beneath the surface of the liquid. If a fill-type cell is used, pour the specimen into the conductivity cell.
8.6 Read and record the conductivity as described in the

DUP050297932
iracy the
ufacturer's instructions regarding the use of the instrupnt. Avoid measuring times longer than 15 s to prevent ctrocoat sample deposition on the cell electrodes. Perform
xmd measurement on another specimen, repeating steps 3 and 8.6. Calculate the mean of both measurements. 7 Take extreme care to prevent contamination of the pie and equipment. Rinse the cell with deionized water an appropriate solvent immediately after use. Keep cell ~.n and do not allow the dry electrocoat sample to ; rmulate on the interior of the cell.
i. Report

fJO Precision and Bias
I^slO.l Precision--In an interlaboratory study of this test ethod, with five laboratories measuring five electrocoat
bath samples with conductivities ranging from 720 to 1750 pS/cm (microohms/cm), the intralaboratory coefficient of variation was found to be 2.6 % relative at,25 df, and the in terlaboratory coefficient of variation 4.2 % relative at 20 df. Based on these coefficients, the following criteria should be used forjudging the acceptability of results at the 95 % con fidence level:
10.1.1 Repeatability--Two results, each the mean of du plicate determinations, obtained by the same operator on different days should be considered suspect if they differ by more than 7.6 % relative.
10.1.2 Reproducibility--Two results, each the mean of duplicate determinations, obtained by operators in different laboratories should be considered suspect if they differ by more than 16.5 % relative.
10.2 Bias--No bias has been determined for this test method.

Designation: D 4400 - 89a
Standard Test Method for Sag Resistance of Faints Using a Multinotch Applicator1
This standard is issued under the fixed designation D 4400; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<?) indicates an editorial change since the last revision or reapproval.
N23' --Paragraph 9.3.1,1 was editorially corrected and the year date was changed Oct. 6. 1989.
INTRODUCTION
The multinotch applicator used in this test method is a drawdown blade with a series of notches of successively higher clearance, referred to as the Anti-Sag Meter. See Figs. 1 and 2 for a
representative diagram and photograph. The numerical value for sag resistance obtained with this instrument is referred to as the Anti-Sag Index.
Anti-Sag Meters are made with several clearance ranges for different types of coatings (see 5.1). In developing this test method the task group used ah instrument with a range from 4 to 24 mils, but this test method is applicable to any clearance range, and results using instruments with overlapping ranges correlate and have equal validity.
This test method covers two procedures. Procedure A was developed in 19622,3 and is referenced in U.S. Federal specifications TT-E-508, TT-E-506, and TT-P-15I1. Procedure B is a newer method that obviates concern about the effect of substrate wetting as a possible variable. Numerical values obtained with the two procedures are not necessarily equal, but their rank orders are essentially the same.
A preshear program is essential for a drawdown sag test to duplicate the breakdown in structure that occurs when thixotropic paints are applied by brushout or other practical application methods. The procedures therefore include the preshearing of paints just prior to making test applications.
1. Scope
1.1 This test method covers the laboratory determination of the sag resistance of aqueous and nonaqueous liquid coatings at any level of sag resistance.
1.2 Procedure A is applicable to coatings of any type or color.
1.3 Procedure B is applicable to any type of coating but does not work well with dark colors.
1.4 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

'significance and Use
|4.1 Evaluation of sag resistance is essential in quality ntrol for both producers and purchasers of coatings, .ucal application tests are poor in reproducibility while imetric methods, for example Test Methods D 2196, are '--'onsuming and lack the convincing aspect of actual ging. This method provides simple and rapid tests, '"-ehy sag resistance is demonstrated by a visible sag lei ii, and is rated objectively in terms of numerical values at correlate with brushout test observations.

7.4 Application of Test Coating:
7.4.1 On a plain white test chart as described in 5.2.3, using the appropriate pen described in 5.. 5, rule two parallel lines about 116 in. (40 mm) apart, across the intended path of
the drawdown blade (see Fig. 4). If desirecl the operator can prepare a supply of such charts for future use, since the ink line is unaffected by aging.12
7.4.2 Affix the ruled test chart onto the drawdown plate and fasten the straightedge in suitable position.
7.4.3 Place the Anti-Sag Meter at the top of the chart, the open side toward the operator and shoulder against the straightedge guide.
7.4.4 If desired, position a catch-paper just underneath
the lower edge of the chart. 7.4.5 Preshear in accordance with 6.2 or 6.3 and immedi
ately draw down the coating at a uniform speed of about 6 in. (150 mm)/s, with one arm ofthe applicator pressed gently against the straightedge to maintain a straight path. This procedure is the same as that referred to in 6.4 and illustrated in Fig. 5.
7.4.6 Fifteen seconds after completing the drawdown, hang the chart with the stripes vertical (like fence pickets), thinnest stripe to the left, and allow to dry in that position. A
typical test pattern obtained using this procedure is shown in Fig. 4.
7.5 Rating the Drawdown: 7.5.1 When the film is dry, note the notch numbers marked on the Anti-Sag Meter and identify the corre sponding stripes and sag loops accordingly.
7.5.2 Examine Fig. 6 and note the "reference loop," which was selected because it indicates a limited but unambiguous sag movement. By actual measurement this loop represents '/u in. (1.5 mm) of sagging, which amount can be considered as defining the reference loop.
7.5.3 For each of the two ink lines on the test drawdown, note the loop that shows the same or almost as much sag as the reference loop. This is referred to as the "index" loop. The loop to its immediate light is the "post-index" loop and the corresponding stripes are the "index" and "post-index" stripes.
7.5.4 Estimate the visual difference between the index and reference loops as a fraction (to the nearest fifth or half) of the difference between the index and post-index loops. This is the addendum fraction, permissible values being 0, 0.2, 0.4, 0.5, 0.6, or 0.8.
7.5.5 Multiply the addendum fraction from 7.5.4 by the difference between the index and post-index stripes to obtain the index addendum.
7.5.6 For each ink line, add the index addendum to the index strip'e number to obtain the Vertical Anti-Sag Index and record the mean value.

Thus, Procedures A and B are approximately three tin more sensitive to differences in sag resistance than brushouts
9.3 Precision: 9.3.1 Two interlaboratory tests were conducted to est; lish the precision of this test method. The first test was tl described in 9.1. The second test consisted of operators m five laboratories performing three tests on each of thiee paints. On the basis of the second interlaboratory test, ihe within-laboratory pooled coefficients of variations for both water- and solvent-reducible paints were 4.4 % for Procedure A and 5.0 % for Procedure B. On the basis of the first interlaboratory test, the between-laboratory pooled coefiicient ofvariation for Procedure A was found to be 12.4 % for
water-reducible paints and 8.8 % for solvent-reducible paints. The between-laboratory pooled coefficient of-varia tion for Procedure B was found to be 8.0 % for waterreducible paints and 6.6 % for solvent-reducible paints, Based on these coefficients of variation, the following critena should be used for judging the acceptability of results at ihe | 95 % confidence level:
9.3.1.1 Repeatability--Two results obtained by the same operator for either water-reducible or solvent-reducible paints should be considered suspect if they differ by more than 10.7 % using Procedure A and by more than 13.6 using Procedure B.
9.3.1.2 Reproducibility--Two results obtained by opera tors in different laboratories using Procedure A should be suspect if they differ by more than 34.4% for v.jii, reducible paints and 23.4 % for solvent-reducible paints. Two results obtained by operators in different laboratories using Procedure B should be suspect if they differ by more' than 23. i % for water-reducible paints and 19.8 % for solvent-reducible paints.

4. Significance and Use
4.1 Wet film thickness measurements of coatings applied on articles can be very helpful in controlling the thickness of the final dry coating, although in some specifications the wet film thickness is specified. Most protective and high perform ance coatings are applied to meet a requirement or specifica tion for dry film thickness for each coat or for the completed coating system, or for both.
4.2 There is a direct relationship between dry film thick ness and wet film thickness. The wet film/dry film ratio is determined by the volume of volatiles in the coating as applied, including permitted thinning. With some flat coat ings the dry film thickness is higher than that calculated from the wet film thickness. Consequently, the results from the notch gage are not to be used to verify the nonvolatile content of a coating.
4.3 Measurement of wet film thickness at the time of application is most appropriate as it permits correction and

5.1 Report the following information: 5.1.1 The mean and range of the readings taken and the number of readings. 5.1.2 The smallest graduation of the gage used.
6. Precision and Bias
6.1 The precision and bias of Procedure A or B for measuring wet film thickness with notch gages are very dependent on methods of film application, time that the measurement is taken after film application, mechanical condition of the notch gages, and the step range of the gages.
6.2 Generally, the agreement between notch gages is good because they are insensitive to small differences in film thickness, that is the step intervals of the gages are relatively large.
PROCEDURE A
7. Apparatus
7.1 Notched Gage, square or rectangular, thin rigid metal plate, with notched sides (see Fig. 1), made from steel or aluminum3 (Note 1). Nonmetallic gages shall not be used.
N;<' 1--Aluminum or aluminum alloy gages'are more easily
distorted and may exhibit greater wear than steel gages. Gages made of plastic or deformable metal are not suitable.
7.1.1 Each notched side shall consist of a series of tabs (between notches) varying in length and located in a line between two end tabs equal in length and longest in the row.
7.1.2 As an example, the tabs on one row of a gage may differ in length as follows: By 0.5 mil (13 pm) between 0 and 6 mils (0 to 150 pm). By 1 mil (25 pm) between 6 and 10 mils (150 to 250 pm), By 2 mils (50 pm) between .10 and 30 mils (250 to 750 pm),
and By 5 mils (125 pm) over 30 mils (750 pm).
8. Procedure
8. i Apply the coating material to a rigid substrate and test with the gage immediately. The gage must be used immedi ately following application of the coating, Some coatings lose solvents quickly and spray application increases the speed. The resulting rapid reduction in wet film thickness can cause misleading readings.
8.2 Locate an area sufficiently large to permit both end tabs of the gage to rest on the substrate in the same' plane.
8.3 Push the gage perpendicularly into the wet film so that the two end tabs rest firmly on the Substrate at the same time.
8.4 Or, set one end tab firmly on the substrate and lower the gage until the other end tab is firmly in contact with the substrate.
8.5 Remove the gage from the film and examine the tabs.
* These gages are commercially available from various coating equipment and instrument suppliers.

8.6 Clean the gage immediately after each reading by
wiping it on a dry or solvent-dampened cloth so that
subsequent readings are not affected. Do not clean with
metal scrapers.
8.7 Repeat the procedure in 8.2 through 8.5 for at least
three locations on the film. The number of readings required
to obtain a good estimate of the film thickness varies with the
shape and size of the article being coated, with the operator's
experience, and whether one or more of the following
problems are encountered:
8.7.1 Some coatings may not wet (leave residue or
metal gages. However, the film itself may show when:
contact was made. When reading the gage, look at both the.
gage and the film itself for verification of the reading.
8.7.2 The gage may slip on the surface. Ignore such read
ings.
8.7.3 The surface may be coarse and false readings pro
duced. The spot where the gage is used must be as unik i m
possible and questionable readings ignored.

Standard Test Methods for Field Measurement of Surface Profile of Blast Cleaned Steel1
1. Scope
1.1 These test methods cover the description of tech niques for measuring the profile of abrasive blast cleaned surfaces in the laboratory, field, or in the fabricating shop. There are additional techniques suitable for laboratory use not covered by these test methods.
1.2 This standard may involve hazardous materials, oper ations. and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility ofwhoever uses this standard to consult and establish appropriate safety and health practices and deter mine the applicability ofregulatory limitations prior to use.
2. Summary of Method
2.1 The methods are: 2.1.1 Method A--The blasted surface is visually compared to standards prepared with various surface profile depths and the mode determined. 2.1.2 Method B--The depth of profile is measured using a fine pointed probe at a number of locations and the arithmetic mean determined. 2.1.3 Method C--A composite plastic tape is impressed into the blast cleaned surface forming a reverse image of the profile, and the peak to valley height on the tape measured with a micrometer.
3. Significance and Use
3.1 The height of surface profile has been shown to be a factor in the performance of various coatings applied to steel. For this reason, surface profile should be measured prior to coating application to ensure that it meets the specification. The instruments described are readily portable and suffi ciently sturdy for use in the field.
N=>' --Optical microscope methods serve as a referee method for
surface profile measurement. Profile depth designations are based on the concept of average maximum profile (7r max); this value is determined by averaging a given number (usually 20) of the highest peak to lowest valley measurements made in the field of view of a standard measuring microscope. This is done because of evidence that coatings performance in any one small area is primarily influenced by the highest surface features in that area and not by the average roughness.12
4. Apparatus 4.1 Method A--A profile comparator3 consisting of a
number of areas (each approximately one square inch in size), usually side by side, with a different profile or anchor

pattern depth. Each area is marked giving the nominal
profile depth in mils or micrometres. Typical comparator surfaces are prepared with steel shot, steel grit, or sand or other nonmetallic abrasive, since the appearance of the profile created by these abrasives may differ. The comparator areas are used with or without magnification of 5 to lOx.
4.2 Method B--A dial gage4 depth micrometer fitted with a pointed probe. The probe is machined at a 60" angle v..ih,

5. Test Specimens
5.1 Use any metal surface that, after blast cleaning, is free ofloose surface interference material, dirt, dust, and abi isiu residue.
6. Procedure
6.1 Method A: 6.1.1 Select the comparator standard appropriate for the abrasive used for blast cleaning. 6.1.2 Place the comparator standard directly on the sur face to be measured and compare the roughness of the prepared surface with the roughness on the comparator segments. This can be done with the unaided eye, under 5 to lOx magnification, or by touch. When using magnification, the magnifier should be brought into intimate contact with the standard, and the depth of focus must be sufficient so
that the standard and surface are in focus simultaneously. 6.1.3 Select the comparator segment that most closely
approximates the roughness of the surface being eval 1 it-c or, if necessary, the two segments to which it is intermediate.
6.1.4 Evaluate the roughness at a sufficient number of locations to characterize the surface as specified or agreed upon between the interested parties. At each location make three evaluations against the comparator and determine the mode. The mode of the three evaluations represents the profile at the specific location, with the mode of all locations representing the profile of the entire surface.
6.2 Method B: 6.2.1 Prior to use set the gage to zero by placing it on a piece of plate glass. Hold the gage by its base and press firmly against the glass. Adjust the instrument to zero. 6.2.2 To take readings, hold the gage firmly against the prepared substrate. Do not drag the instrument across the

Standard Test Method for Visual Evaluation of Gloss Differences Between Surfaces of Similar Appearance1
This standard is issued under the fixed designation D 4449; the number immediately following the designation indicates the year of original adaption or, in the case of revision, the year oflast revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<) indicates an editorial change since the last revision or rcapprovui.
1. Scope 1.1 This method covers the visual evaluation of gloss
differences of coating surfaces, using special types of lamps for illumination. It identifies six aspects or types of gloss that one may look for when using the lamp to assess gloss differences between surfaces. It describes the conditions for using the lamps to best identify small differences in each of the six types of gloss. Four levels of visual gloss differences are distinguished.
1.2 While this technique is useful for both weathered and unweathered specimens, it has not been applied to mctallics.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3.2.5 sheen--perceived shininess at a near-grazing an(<f of incidence for an otherwise matte specimen (difficult i photograph).
3.2.6 specular gloss--the relative luminous refle. factor of a specimen in the specular direction. The luminou reflectance factor is the ratio of the luminous flux refle from, to that incident on, a specimen for specified soli angles (see Fig. 4),
3.2.7 texture--perceived structure, pattern, or topograj or combination thereof, of a surface (see Fig. 5).
4. Summary of Test Method
4.1 Test specimens are illuminated by special light soun that provide reflected images suitable for rating the gloss t coating surfaces. Two types of lamps may be used to produ6 reflected images. Lamp A consists of a modified fluoresceni desk lamp covered with screen mesh. Lamp B consists ofaij incandescent bare filament bulb installed in an adjustall angle fixture.
4.2 Light from the selected lamp illuminates thi specimens. The reflected images reveal specular gloss ref, tion; the sharpness of the images of the screen or Ian filament reveals the detail and quality of the surface tion (distinctness of image); and spreading of the ref light into dark areas? such as the space between fluoicsc^ tubes or near the filament image, reveals the presencsllj near-specular haze.
5. Significance and Use
5.1 Gloss4 is associated with the capacity of a surface 1 reflect more light in some directions than in others, directions associated with mirror (or specular) refleclic normally have the highest reflectances. Gloss is best seen aril analyzed when the surfaces studied are illuminated by a 1. source that provides strong contrasting patterns of light f dark. Such a light source is described in this test method.
5.2 The simplest concept of gloss is that it corresponds! the mirror-like reflectances of surfaces. However, the < butions and intensities of this surface-reflected light are (fi real materials) highly variable and affected by a variety i factors: surface smoothness and contour, refractive ind absorptance, angle of incidence, and (to a generally sn extent) wavelength. From the great variety of surface;

7.1 Calculate the percent pigment, P, as follows:
P = C-^Axioo where: C = weight of dish and specimen after ignition in furnace,
g, : A = weight of dish alone, g, and S' = specimen weight used, g.` 1
8. Precision
8.1 The precision estimates are based on an interlabora tory study in which one operator in 7 different laboratories
analyzed in duplicate on two days six samples of commercial whole paint or thermoplastic material containing 50 to 80 % pigment. The results were analyzed statistically in accor dance with Practice E 180 and the within-iaboratory coeffi
cient of variation was found to be O.lO^ relative at 36 df and the between-laboratories coefficient of variation 0.25 % relative at 30 df. Based on these coefficients the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
8.1.1 Repeatability--Two results, each the mean of dupli cate determinations, obtained by the same operator on different days should be considered suspect if they differ by more than 0.28 % relative.
8.1.2 Reproducibility--Two results, each the mean of
duplicate determinations, obtained by operators in different laboratories should be considered suspect if they differ by more than 0.72 % relative.:

;.l This test method covers the determination of total unt of dichloromethane or 1,1,1-trichloroethane, or in paints and coatings. It has been evaluated for
'{llose nitrate, alkyd, vinyl, and styrene-butadiene systems, as not yet been eyaulated for other formulations, but is eved to be applicable. The established working range of !|test method is from 31 to 65 % for 1,1,1-trichloroethane 32 to 78 % for dichloromethane. There is no reason to 'eve it will not work outside of these ranges. The presence ijrpropanol in paints and coatings requires the use of a erent internal standard. (See also Practice E 260.) |2 This standard does not purport to address all of the Jp problems, if any, associated with its use. It is the onsibility of the user of this standard to establish appro ve safety and health practices and determine the applicaj of regulatory limitations prior to use. Specific hazard raents are given in Section 7.

IE 260 Practice for Packed Column Gas Chromatography3
fSummary of Test Method
f.l Anhydrous 1-propanol (see 10.5) is added as an temal standard to suitable aliquot of the whole paint. The
uot is then diluted with dimethylformamide and injected a gas chromatographic column containing a porous
Jymer packing that separates dichloromethane and 1,1,1chloroethane from other volatile compounds.
I' Significance and Use
4.1 Use of 1,1,1-trichloroethane and dichloromethane, v Inch do not measurably contribute to the atmospheric jaxidant level, is a way for industry to meet government or
other regulations on volatile organic compounds. This test method is designed to determine the content of these halohydrocarbon solvents in paints and coatings. That con tent can subsequently be used in calculating the volatile organic compound content of a coating.
5. Apparatus
5.1 Chromatograph, any gas-liquid chromatographic in strument equipped with a thermal conductivity detector and capable of being temperature programmed (see Table 1). Optionally, a flame ionization detector may be used if the sample is diluted so that no more than 1000 ppm each of dichloromethane and 1,1,1-trichloroethane is present in the injected specimen.
5.2 Recorder, a recording potentiometer with a full-scale deflection of 10 mV, a full-scale response time of 2 s or less, and a maximum noise of 0.03 % of full scale.
5.3 Pre-Column, 40 in. (100 mm) long by '/in. (3.2 mm) outside diameter stainless steel, packed with glass wool, fitted on the entrance end of the column to retain any nonvolatile materials and minimize sludge buildup in the column.
5.4 Column, 4 ft (1.22 m) long by '/s in. (3.2 mm) outside diameter stainless steel, packed with 80/100 mesh (150 to 180 pm) porous polymer packing material,4 5or other suitable material.
5.5 Liquid Charging Devices, such as microsyringes of 5-pL or 10-pL capacity, cleaned with acetone or other suitable solvent. Visually inspect for plugs or cracks before and after each injection.
5.6 Vials, 25-mL to minimize head space, capable of being septum sealed.3

6.3 Dimethylformamide (DMF), reagent grade. 6.4 1-Propanol, gas chromatography spectrophotometric quality (see 10.5). 6.5 1,1,1-Trichloroethane (see 6.7). 6.6 Dichloromethane (see 6.7). 6.7 Halogenated Hydrocarbon Stabilizers--All commer cial grades of these halogenated hydrocarbons contain stabi lizers. Either obtain the same solvent used in the coating for use as the standard, or find the type and quantity of stabilizer specified for use in the solvent of interest and add the appropriate quantity to the pure solvent.
7. Hazards
7.1 Dimethylformamide is harmful if inhaled or absorbed through skin. Use only with adequate ventilation. Avoid contact with skin, eyes, and clothing.
8. Preparation of Apparatus
8.1 Column Conditioning--The packed column is in stalled in the gas chromatographic unit leaving the exit end disconnected from the detector. This will prevent any contamination of the detector with the column bleed. Set the helium flow rate at 30 mL/min if a Vs in. (3.2 mm) outside diameter column is used. Purge the column 5 to 10 min before heating. Heat the column from room temperature to 200C at 5C/min and hold this temperature for at least 12 h (overnight). At the end of this period of time, heat the column to 240C at a 5C/min rate and hold this tempera ture for several hours. The maximum temperature for this packing is 250C. Cool the column to 100C and reheat to 240C at 5C/min to observe the column bleed. Optimum conditioning of this column may take several cycles of the heating program before a good recorder baseline is achieved. Conditioning of any column other than that suggested (5.4) should be in accordance with the manufacturer's recommen dations. ,
8.2 Install the column in the chromatograph and use the information in Table 1 as a guide to establish the conditions required to give the desired separation. Allow sufficient time for the instrument to reach equilibrium as indicated by a stable recorder baseline. Adjust the carrier-gas flow to a constant rate. Before each calibration and series of determi nations (or daily), condition the column at 200'C for 1 h with carrier-gas flow.
9. Calibration
9.1 Preparation of Standards--All standards, as well as samples and blanks, should be at a constant temperature. The given order of ingredient addition should be observed to minimize loss of volatile ingredients.

12.1 Precision: 12.1.1 J,1,1-Trichloroethane--On the basis of an inter laboratory test of this test method in which one operator in each of eight laboratories tested three coatings containing from 31 to 65% 1,1,1-trichloroethane (theoretical), the within-laboratory coefficient of variation was found to be 1.01 % relative at 20 degrees of freedom and the betweenlaboratories coefficient of variation was found to be 2.72 % relative at 17 degrees of freedom. Based on these coefficients, the following criteria should be used for judging the accept ability of results at the 95 % confidence level:
12.1.1.1 Repeatability--Two results, each the mean of duplicate runs, obtained by the same operator should be considered suspect if they differ by more than 3.0 % relative.
12.1.1.2 Reproducibility--Two results, each the mean of duplicate runs, obtained by operators in different laborato ries should be considered suspect if they differ by more than 8.1 % relative.
12.1.2 Dickloromethane--On the basis of an inter laboratory test of this test method in which one operator in each of eight laboratories tested two coatings containing from 32 to 78 % dichloromethane (theoretical), the withinlaboratory coefficient of variation was found to be 0.98 % relative at 14 degrees of freedom and the between-laboratories coefficient of variation was found to be 5.16 % relative at 12 degrees of freedom. Based on these coefficients, the following criteria should be used forjudging the acceptability of results at the 95 % confidence level:
12.1.2.1 Repeatability--Two results, each the mean of duplicate runs, obtained by same operator should be consid ered suspect if they differ by more than 3.0 % relative.

ii Terminology
3.1 Definition: 3.1.1 static friction--the force required to start the test fjjed moving, divided by the mass of the sled.
ft Summary of Test Methods
4.1 With the inclined plane test (Test Method A), a jweighted sled is placed on a test specimen and the specimen fs gradually inclined from the horizontal until the sled begins
t slide. The tangent ofthis angle of inclination is reported as lie static friction. ' 4.2 With the horizontal pull test (Test Method B), a
ighted sled is placed on a horizontal test specimen and is pulled across the specimen. The static friction is reported as Ihe force required to start the sled moving, divided by the mass of the sled.
5. Significance and Use
5:1 The friction characteristics of coating surfaces can be important to the use of the coatings. For example, low friction of exterior can coatings is beneficial to the flow of the cans on production lines. Also low friction of interior pipeline coatings is beneficial to the flow of materials

through pipes. On the other hand, low friction of floor coatings can be hazardous to foot traffic.
5.2 Under some conditions, measurement of the static friction can be used to evaluate the slip resistance ofcoatings under use conditions. However, results can be extremely dependent on the type of coating surface and the type of sliding unit used.
5.3 The tendency for footwear to slip may be influenced by foreign materials or lubricants on the shoe materials or on the walking surfaces. Also, these test methods do not incorporate all the directional forces involved in the walking process. Consequently, levels of slip resistance as determined by these test methods may not predict a person's resistance to slipping when walking on various surfaces.
5.4 The best precision and sensitivity are obtained when stainless steel is used as the facing of the sliding unit. In some tests where a leather facing is used, poor precision is obtained because of the inability to control the uniformity of its surface during the test. The use of a hard synthetic robber facing provides somewhat better precision.
5.5 These test methods provide for static friction measure ments when the sled facing and the coating surfaces are wet with water. Results from such tests must be treated with caution because frequently the static friction values obtained for wet, smooth coatings are higher than those obtained for the same surfaces dry. This is because, when stationary at tire beginning of the test, the sled contact can produce a "suction cup" effect on a wet surface. Measurements performed on wet coatings with rough surfaces have been more satisfac tory.
5.6 A test procedure is offered that eliminates the "suction cup" effect of wet surfaces. The wet sled is dropped onto the wet coating surface at the start of the test.
5.7 Results obtained by these test methods may be ex tremely sensitive to the age of the test coating because the blooming action of additives or plasticizers is often timedependent. It may be meaningless to compare slip and frictional properties oftest coatings applied at different times unless this effect is being studied.
5.8 The measurement of static friction may be influenced by the length of time that the sled rests on the test specimen before motion is initiated.
5.9 Static friction measurements have been useful in evaluating (/) the suitability of coatings for the exterior of cans, (2) the slipperiness of floor polishes, and (i) the slip resistance characteristics of footwear on floor tiles and floor coatings. Also, static friction measurements have been useful in determining the effect of coating additives (for example waxes, silicones) on the slipperiness of coating surfaces.

6. Test Specimens
6.1 Apply test coatings in accordance with Test Methods D 823 to substrates of at least 4 in. (100 mm) in width and length. The substrates may be of glass, steel, aluminum, or other appropriate material that remains smooth and plane after the test coating has been applied and cured at 73.5 3.5F (23 2'C) and 50 5 % relative humidity for 7 days, unless otherwise specified. Prepare at least two test panels for each coating.
6.2 Take care during application of the test coating to minimize entrainment of dust and particulate matter in the surface of the coating. Extreme care is required when handling the panels, even after sufficient cure. The surface should be kept free of all dust, lint, fingerprints, or any foreign matter that may change the characteristics of the surface.
7. Conditions for Testing
7.1 Test the coated test specimens under one or more of the following conditions as agreed upon by the purchaser and the seller:
7.1.1 Both sled facing and coating surfaces dry at 73.5 3.5F (23 2C).
7.1.2 Both the sled face and the coating surface wet with water containing a slight amount of wetting agent at 73.5 3.5'F (23 2C). Sea water containing a slight amount of wetting agent may be used when it is appropriate. A wetting solution consisting of 1 mL of surfactant3 added to 200 mL of water has been found to be satisfactory.
7.1.3 One or both of the above at 35.5 3.5F (2 2"C).
TEST METHOD A--INCLINED PLANE TEST
8. Apparatus
8.1 Inclined Plane, having a smooth, incompressible sur face, at least 1 in. (25 mm) wider than the sliding unit and of sufficient length to allow the test sled to move by gravity at least 0.5 in. (12 mm), provided with clamps for the test specimen, and an inclinometer to indicate the angular displacement of the plane to within 0.5".
NIJ' 1--A suitable apparatus is shown in Fig. 1. It may be
assembled from items obtained from laboratory instrument supply houses.
8.2 Test Sleds--Alternative sleds that may be used are: 8.2.1 Stainless Rounded Edge Steel Block, with a highly polished plane lower surface 3 by 3 in. (75 by 75 mm) in area and a mass of 1.8 lb (0.82 kg) to provide a pressure of 0.2 psi (1.4 kPa) when horizontal. 8.2.2 Stainless Steel Block, with a plane lower surface of 3 by 3 in. (75 by 75 mm) and a mass of 1.8 lb (0.82 kg). Adhered to the lower surface is a `A-in. (6-mm) thick vulcanized neoprene rubber having a Shore "A" hardness of 65 5. A screw eye or other means to attach the sled to the force-measuring device is provided. 8.3 Inclinator--Means to smoothly increase the inclina tion of the plane from the horizontal through an arc of at

a motor driven dip coater and (2) pushing the top of the plane up with a laboratory jack equipped with a hand crank.
9. Preparation of Apparatus
9.1 Preparation ofSled Facing: 9.1.1 If a synthetic rubber facing is used on the test sled, it must be preconditioned by light sanding before each deter mination. 9.1.2 Place a sheet of 400A wet or dry silicon carbide abrasive paper on a flat surface. Sand the synthetic ruhl i1 facing by rubbing it gently back and forth over the paper fe tv times. Repeat at 90 to the first direction. Wipe the surface of the synthetic rubber facing with a clean, dry cloth to remo dust or loose material from the surface.
10. Procedure
10.1 Level the plane so it is horizontal when the inclinom eter reads zero.
10.2 Clamp the test specimen to the plane. Recheck the levelness of the panel in two directions (along the length f* the panel and across the panel at 90 to the first measutv.ment).
10.3 Dry Surfaces: 10.3.1 Center the sled on the test coating. Immediately commence inclining at a rate of 1.5 0.5/s. When the sled starts to move, stop the inclinometer immediately and read the angle of displacement at the moment the sled starts to move. 10.3.2 Return the plane to a level position and make two additional tests on the test specimen as described in 8.3. 10.4 For Wet Surfaces: i 0.4.1 Check levelness of plane and test panel accordi to procedures given in 10.1 and 10.2. 10.4.2 Wet the test coating surface and the sled facing with the prescribed solution.

13.1.1 Repeatability--Two results obtained by the same operator should be suspect if they differ by more than the maximum allowable difference given in Table I.
13.1.2 Reproducibility--Two results obtained by opera tors in different laboratories should be considered suspect if they differ by more than the maximum allowable difference given in Table 1.
13.2 Comparison of inclined plane results are shown in Table!

13.3 Bias cannot be determined since there is no standard for slipperiness or slip resistance.
TEST METHOD B--HORIZONTAL PULL TEST
14. Apparatus4
14.1 Test Base, a horizontal plane surface of a smooth, incompressible material (metal, wood, plate glass, or plastic) having a width at least 1 in. (25 mm) wider than the test sled (14.2) with means of leveling it in two directions. This base serves as a support for the rest of the mechanism and the test specimen. When placed on a solid support, it must be free of vibration.
14.2 Test Sleds--Alternative sleds that may be used are: 14.2.1 Stainless Steel Block, with a highly polished lower plane surface of 3 by 3 in. (75 by 75 mm) and a mass of 1.8 lb (0.82 kg) to provide a pressure of 0.2 psi (1.4 MPa) on the horizontal surface. A screw eye or other means to attach the sled to the force-measuring device is provided. 14.2:2 Steel Block, with a smooth lower surface of 3 by 3 in. (75 by 75 mm) in area and a mass of 1.8 lb (0.82 kg). Adhered to the lower surface is a Vi-in. (6-mm) thick vulcanized neoprene rubber having a Shore "A" hardness of 65 + 5. A screw eye or other means to attach the sled to the force-measuring device is provided. 14.2.3 Steel Block, having a smooth lower surface 4 by 5 in. (100 by 125 mm) in area and a thickness of 1 to 1.5 in. (25 to 40 mm). Adhered to the lower surface is vulcanized neoprene rubber haying a Shore "A" hardness of 65 5 and a thickness of '/' in. (3 mm). The total mass of the sled with the rubber facing shall be 6.0 0.5 lb (2.7 0.2 kg). 14.3 Mechanical Power Unit--Means for.moving the test sled horizontally over the test specimen or the test specimen under a fixed test sled under the following conditions: 14.3.1 For the sleds described in 14.2.1 and 14.2,2, a speed of 6.0 1.0 in./min (150 25 mm/min) shall be provided and a sled (or panel) travel of 4.in, (100 mm). 14.3.2 For the sled described in 14.2.3, a speed of .12 1 in. (300 25 mm)/min shall be provided and the sled (or panel) allowed to travel 4 in. (100 mm). 14.3.3 Force Measuring Device--Means for measuring the force to 0.01 lb (0.04 N) required to move or restrain the test sled.
NNO' 3--A force gage5 that can be preset to display the highest force
encountered is desirable.
NPQ' 4---Figure 2 illustrates a suitable apparatus. There are various
commercial instruments available but some require modification to meet the requirements of these test methods.
15. Preparation of Apparatus
15.1 Preparation ofSled Facing: 15.1.1 If a synthetic rubber facing is used on the test sled, it must be preconditioned by light sanding before each determination. 15.1.2 Place a sheet of 400A wet or dry silicon carbide abrasive paper on a plane surface. Sand the synthetic rubber facing by rubbing it gently back and forth over the paper four
4 A facing of heel material such as Neolile, with a Shore "A" hardness of 95 5 may be used if appropriate.
5 Chatilton dynamometer gages, available from Chatillon, Inc., 83-30 Kew Garden Rd., Kew Garden, NY 11415, have been found suitable for this purpose.

times. Repeat at 90" to the first direction. Wipe the surface of*<J the synthetic rubber facing with a clean, dry cloth to remove ' dust or loose material from the surface.
16. Procedure
16.1 Select the test sled and traverse the speed appropriate for the type of test desired:
16.1.1 The test sled described in 14.2.2 with a traverse speed of 6 in. (150 mm)/min is recommended if the best,,' precision of measurement on a smooth coating is desired
16.1.2 The test sled described in 14.2.2 with a traverse speed of 6 in. (150 mm)/min is recommended if it is desired to measure the resistance of a smooth coating to the slipping of a rubber shoe heel or sole.
16.1.3 The test sled described in 14.2.3 with a traverse speed of 12 in. (300 mm)/min is recommended if it is desired to measure the resistance of a rough coating to the slipping of a rubber shoe heel or sole.
16.2 Clamp the test specimen to the base. Position the,t ,t , sled and connect it to the power unit or force gage. Fasten the inelastic linkage (cable or chain) to the test sled and|j connect to the power unit or the force gage.
16.3 As soon as possible after positioning the sled, star! t the power unit, taking care to maintain tautness in them linkage as the power unit takes up the load.
16.4 Record the force required to just begin motion of the test slide; that is, the maximum force value recorded.
16.5 For the evaluation of smooth coatings, make two additional determinations on the test specimen as describee in 16.1 through 16.4. For the evaluation of rough coatings, make four additional determinations on the test specimen.
17. Calculation
17.1 Calculate the mean of the force value obtained foi the replicate determinations.
17.2 Divide the mean force by the mass of the test sled. This is the static friction value.

3. Terminology
3.1 Definitions: 3.1.1 For definitions of terms used in this guide, see Terminology D 16.
4. Conditions Affecting Latex Semigloss and Gloss Paints
4.1 Substrate Type--The substrate to be painted can affect not only the application properties and the physical properties of a latex paint, such as gloss and uniformity, but may also be a factor in determining the type of latex paint to be used;
4.2 Substrate Condition--Dirty, alkaline, or water-soluble surfaces may affect the practical requirements and perfor mance of these paints.
4.3 Application Properties--The application properties of paints are affected by temperature, humidity, and the texture and porosity of the surface to be painted. Application is also affected by the type and quality of equipment used.
5. Selection of Tests
5.1 Many conditions affect interior latex semigloss and gloss paints, so that different types of latex paints have been developed specifically to meet the requirements of these various conditions. Although the recommended test methods in Tables 1 and 2 edver most ofthe properties of such paints, all of the tests may not be required for each paint. If a paint is to Be used only in a warm cliniate for instance, then freeze-thaw tests or low temperature coalescence tests need not be considered.
5.2 The purchaser should first determine which properties a latex paint must have and then select only the test methods that will measure or evaluate those properties. After selecting the desired tests, the purchaser should determine which of these properties are the most important and establish the appropriate requirements or specifications for obtaining the desired properties. Since paint properties frequently tend to oppose each other, some properties may need to be attenu ated if others are to be accentuated. This balance of properties must be considered when selecting the tests and establishing their requirements. A normal range of values is indicated in many of the tests methods.
5.3 This guide docs not indicate relative importance ofthe various tests nor does it recommend specific values for each test, since the properties that are important to one purchaser may hot be important to. another.
6. Sampling
6.1 Prior to sampling, the condition of the container should be established since damage to it may cause evapora tion or skinning of the pigment or other undesirable effects in the coating. Determine the condition of the coating in accordance with 7.1 and 7.2.
6.2 Sample in accordance with Practice D 3925. Deter mine the weight per gallon in accordance with Test Method D 1475. Repeat this procedure until successive readings agree within 0.2 lb (90 g) or as agreed upon between purchaser and seller. Samples for testing may then be taken.

Be also 7.7 on Package Stability:) 117.2 Coarse Particles and Foreign Matter: |7:2.1 Paints must be free of coarse particles to form aifcrm films of good appearance, a typical maximum being jjpeight % of total paint, The specified test with a 325-mesh S-pm) screen and water as the wash liquid gives the percent ll'ihese particles in a latex paint. Determine coarse particles |fd foreign matter in accordance with Test Methods D 185.
17.2.2 Another test method used in industry to determine giether coarse particles are present in a dry film is to scrape
: surface of the film with a spatula or metal edge of a ruler, ay particles larger than 325 mesh (45 pm) can be clearly geen after the surface has been scraped. . M 7.3 Density (Weight per Gallon)--The density as mea
sured by weight per gallon (kilograms per litre) is used to
assure product uniformity from batch to batch. It does not
necessarily measure the quality of a paint. In the referenced
method, the density is expressed as the weight in pounds per
U.S. gal (or kg/L) of the paint at a specified temperature.
Most interior semigloss and gloss paints have densities of
about 10 to 12 lb/gal (1.2 to 1.4 kg/L). Determine density in
accordance with Test Method D 1475.
7.4 Fineness ofDispersion:
7.4.1 The more finely a pigment is dispersed, the more
efficiently it is being used. One method for measuring the
degree of dispersion (commonly referred to as "fineness of
grind") is to draw the material down a calibrated tapered
groove varying in depth from 4 to 0 mils (100 to 0 pm). The
Hegman scale is one commonly accepted measurement
method. The point at which the continuous groupings of
particles or agglomerates, or both, protrude through the
surface of the liquid is taken as the fineness reading. Lower
readings in mils or micrometres or higher readings in
Hegman units indicate better fineness dispersion. Measure
fineness of dispersion in accordance with Test Method
D 1210.
7.4.2 The referenced method was designed primarily for
coatings with good fineness of dispersion such as enamels.
Most interior semigloss and gloss latex paints have a fineness
of about 7.5 to 5 Hegman (6 to 40 pm).
7.5 Odor--One of the advantages of latex paints is that
they do not have odors characteristic of solvent-reducible
coatings. However, other ingredients, such as ammonia, may
be used that might also be objectionable in confined spaces.
Thus, interior latex paints should be tested for odor accept
ability. Determine whether the paint has an unpleasant or
irritating odor during application or drying.
7.6 Color Compatibility--A test method to determine
how well colorants can be dispersed in paints so that the
paint will have uniformity of color when applied is in
preparation and will be included in the guide when adopted
by AS TM.
>
7.7 Package Stability--Since paints cannot normally be
used immediately after manufacture they must remain stable
in the can for some time, At normal temperatures, most latex
paints can be stored for over a year with little change in
properties. Although indications of long term package sta
bility can usually be obtained in several days or weeks at an
elevated temperature, such as 140F (60C) or 122F (50C),
occasionally the results of the accelerated test do not agree
with those at prolonged normal storage conditions. The
referenced method predicts the change in consistency and
certain other properties in packaged latex paint when stored
at temperatures above freezing. Determine package stability
in accordance with Test Method D 1849.
7.7.1 Heat Stability--Heating is used to accelerate
changes in viscosity with time and to predict their affect on
other properties. An excessive increase or decrease in vis
cosity after heat-aging is unacceptable. There is a general
correlation between short-term high temperature oven sta
bility and long-term shelf storage at ambient temperature.
This test is meant to predict which paints will not be stable
when stored by customers or consumers under elevated
temperature for a short period of time or at room tempera
ture for a longer period of time. After heat-aging, such
787
DU PO 502 97969
D 4540
properties as viscosity, flow, gloss, pH drift, foam resistance, color uniformity, and wet adhesion are usually rechecked versus room temperature-aged controls.
7.7.2 Freeze-Thaw Stability--Water-reducible paints may be subjected to freezing conditions during shipping and storage. Suitably stabilized paints will resist several cycles of freezing and thawing without showing deleterious changes such as coagulation, graininess, or excessive viscosity in crease. Many latex paints will increase in viscosity but can still be considered satisfactory if other properties that may be affected by a higher viscosity) such as leveling and brushability, are satisfactory. Determine freeze-thaw stability in accordance with Test Method D 2243.
7.7.3 Microorganism Resistance--Bacteria in a latex paint can cause gassing, putrefactive or fermentative odors, and loss of viscosity. Determine if the paint contains living bacteria or if it is resistant to attack by bacteria in accordance with Test Method D 2574. :
7.7.4 pH--Latex paints with low (acidic) pH can corrode metai containers. pH may. vary from about 5 to 10 de pending upon the type of latex used and general formulation. pH does not determine the quality of a latex paint and should only be used to assure product uniformity. However, a change in pH during storage may indicate poor stability and unacceptable change in the properties of a paint. Determine pH in accordance with Test Method E 70.
7.7.5 Settling--Latex paints are generally resistant to hard settling, but do at times show separation and soft settling. The referenced method covers the. degree of pigment suspen sion and ease of remixing a shelf-aged sample of paint to a homogeneous condition suitable for the intended use. Deter mine settling in accordance with Method D 869.
8, Paint Application and Film Formation
%A Application. Properties--Determine the ease1 with tehich a paint can be applied to various wall surfaces with brush, roller, or Spray equipment, in accordance with Method 4541 of Federal Test Method Standard No: 141. Application properties are generally compared to a standard, or described by requirements in a product specification.
8.1.1 Brush Application--Brushed films should be smooth and free of seeds and on verticaf surfaces should show no sagging, color streaking, or excessive brush marks. The specified method covers the determination of the brushing properties of coatings. The test is subjective al though those experienced in the art Can' produce quite consistent results, particularly in the evaluation of "drag" properties. Determine brushing properties in accordance with Method 4321 of Federal Test Method Standard No. 141.
8.1.2 Roller Application--Walls are frequently painted with rollers that produce slight stipple effects. Determine the ease with which a paint can be roller applied in accordance with Method 2112 of Federal Test Method Standard No. 141. Since roller foam and roller spatter are often serious problems when latex paints are roller applied, these proper ties can also be determined in the test method for roller application; The amount of foam produced, the time that it takes for the bubbles to break, and the number ofcraters that remain after the bubbles have broken can be determined by visual examination of the test panel. Roller spatter can be
determined by placing a strip of paper or a panel at the
bottom of the test panel to catch the paint spatters from the
roller. The degree to which a paint will spatter when roller
applied can be determined by the density ofthe paint spatter..:
8.1.3 Spray Application--Interior coatings are sometimes?:
applied by spray. Both air and airless spray are used 0n
commerical work. Determine the spray application propen :
ties in accordance with Method 2131 of Federal Test Methdifl
Standard No. 141. The method can be modified to include
application by airless spray equipment.
2|
8.2 Drying Properties--The drying time of an interior
latex paint is important in determining when a freshly
painted room can be put back to use. Under average
conditions most semigloss and gloss latex paints are dry fjf
touch in 1 to 2 h when the water has evaporated from the
film. Because of the glycols usually present in these paints it"
is prudent to recoat after at least an 18-h dry. I
properties may take a few days to develop'for stime i i.
paints while cithers may require a few weeks depend] nr
the composition. Determine the drying time in accordaijh||
with Test Methods D 1640.
8.3 Low-Temperature Coalescence of Paints--T1 enced test method determines how well the latex partieiSS
a paint Mil fuse together or coalesce, to form a contiiM'.ii, ]
film at low temperatures. Determine low-temperatun
cence in accordance with Test Method D 3793.
8.4 Producing Films of Uniform Thickness--The
lowing method covers the preparation of various fi' n; o r
uniform thickness essential in conducting tests. Prepare flints!
in accordance with Test Methods D 823.
8.5 Touch-Up Uniformity--After paint has dried,
where less material was applied sometimes become :
able. If the paint has suitable touch-up properties, ad
paint can be applied to these areas only, instead of reftuf
ishing the complete wall. The color, gloss, and leveling of t
touched-up areas and the previously painted area should.1
uniform. Differences in these properties are often caused:!
short wet edge time, poor leveling on recoat and
orientation or floatation during and after application,
mine touch-up properties in accordance with Test Me
D 3928.
9. Rheological Properties
9.1 Leveling--Leveling is an important factor when i form surfaces are to be produced as it affects hiding ] and appearance. Brush marks, and imperfections are : more conspicuous in semigloss and gloss paints than they?! in flat paints. The referenced method covers the characteristics of liquid coatings. Evaluate leveling in accet-^ dance with Test Method D 4062.
9.2 Low Shear Viscosity (Consistency)--Paints of a j type should fall within a stated consistency ran satisfactory reproduction of a specific formula. While consiS-.: tency is an important property, it does not determine the;,; quality of a paint and should be used mainly to enspfl product uniformity. In the referenced method, cbnsistencyj;|lS defined as the load in grams to produce a specified rate of' shear. Although the consistency of most latex wall paint \ about 150 to'300 g, a much wider range is possible because the wide variations in rheological properties of these paints?

|3 High Shear Viscosity (IC1 Cone and Plate Viscos-The shear rate for this measurement (10 000 reciprocal ttds) is similar to that occurring during brush applicai, and the viscosity measured at this shear rate therefore is 1 to brush drag, which is in turn related to spreading
l^jand film build. Measure the high shear viscosity in ance with Test Method D 4287.
! Sag Resistance--This is an important property particfor semigloss and gloss latex paints because sagging i in unsightly film appearance. Measure the sag fesis-
i in accordance with Test Methods D 4400. Rheological Properties, Non-Newtonian Liquids--
^logical properties are related to application and leveling ties of the liquid paint. The referenced methods cover
Idetermination of rheological properties, and are particu-
suited for use with paints that display thixotropic icteristics. They 'actually measure viscosity under dift shear rates. Determine rheological properties in accorIK with Test Methods D 2196 or D 4287, or both!
|ppearance of Dry Film
`
(jl Color Differences by Visual Evaluation--Visual rison of color is fast and often acceptable although
erica! values are not obtained. The referenced method ; the spectral, photometric, and geometric characterisf light source, illuminating and viewing conditions, size imens, and general procedures to be used in the visual ation of color differences of opaque materials. Deter
ge color differences in accordance with Practice D 1729. p.2 Color Differences Using Instrumental Measure rs--The differences in color between a product and its
trd can be measured by instrument. Generally, the nee is agreed upon by the purchaser and the seller and also be required if a product specification is involved. iBr instruments provide numerical values that can be Spared to subsequent measurements. The referenced
1 covers the instrumental determination of small color iflcrences observable in daylight illumination between
tameric, opaque surfaces such as coated specimens. If j$unerism is suspected, visual evaluation (see 10.1) should
lised to verify the results. Calculate in accordance with ! Method D 2244 the color differences that have been
red instrumentally. |10.3 Hiding Power (Dry Opacity)--Hiding power is the
ure of the ability of a paint to hide the substrate. It is, ever, dependent upon uniform film thickness that is ptienced by flow and leveling. Test Method D 344 is a
test in which paint is applied with a brush, film tkness is approximately measured, opacity is evaluated bally compared to a standard paint, and results are
ed by flow and leveling application properties of the it. Test Method D 2805 is considered to be a more tecise and accurate test that does not need a material paint < iard. Paint is applied with an applicator bar to minimize effects of flow and leveling, film thickness is rigorously \jsured, and opacity is instrumentally evaluated. Deter
mine hiding power in accordance with Test Methods D 344 or D 2805.
10.4 Specular Gloss--The method given, using the 20 geometry for high gloss paints and ,60 geometry for semigloss paints, is useful in characterizing the direct appear ance of gloss and semigloss paints. According to the Paint/ Coatings Dictionary,7 the semigloss range is usually 35 to 70 using the 60 geometry. Full gloss is usually above 70 using the 60 geometry. Although paints with good uniformity of appearance are often paints of lower gloss and paints with good cleanability are often' ones with higher gloss, this is not always the case, and the gloss of a paint should not be used as a measure of other paint properties. Determine the gloss at 20 and 60, as appropriate, gloss in accordance with Test Method D 523.
11. Properties of Dry Film
11.1 Block Resistance--This is an important property of an interior semigloss or gloss since it is the resistance of the painted surfaces to stick together when stacked or placed in contact \tfith each other. An interior paint often comes in contact with itself especially in the cases of doors, windows and drawers and sometimes sticks to itself: (blocks) de pending on the hardness of the coating, the pressure, temperature, humidity, and duration of time the surfaces are in contact.
11.2 Efflorescence of the Paint Film--The referenced method measures efflorescence that comes from the paint itself,- not from the substrate. Few interior latex paints effloresce due to improvements in latex and latex paint formulations. Salt formation is produced by specific condi tions of temperature and humidity if a paint contains sufficient solid water-soluble material to cause a noticeable deposit on the film. Determine efflorescence resistance in accordance with Test Method D 1736.
11.3 Efflorescence from Substrate--Cementitious sub stances may contain sufficient solid water-soluble materials to cause a surface deposft through leaching and evapora tion.
11.4 Flexibility--Elongation is a measure of the flexibility of a paint film. Most interior latex paints can be bent over a `/8-in. (3.2-mm) mandrel without affecting the film. Deter mine elongation in accordance with Test Methods D 522.
11.5 Film Porosity--The more porous a paint is, the worse will be its cleanability and enamel holdout. Determine film porosity in accordance with Test Method D 3258.
11.6 Print Resistance--The ability of a coating to resist printing is important because its appearance is adversely affected if the surface texture is modified by contact with another surface particularly one with a pattern. Interior gloss and semigloss systems on window sills and other horizontal surfaces often have flower pots placed on them that may tend to leave a permanent impression from the pressure. This tendency for a paint film to "print" is often a function of tfie hardness of the coating, the pressure, temperature, humidity, and duration of time that the painted surface is in contact with the object.

11.7 Scrubbability--The ability of an interior finish to resist scrubbing is an important property. The referenced method provides a measure ofthe wet abrasion resistance of a film. However, wet abrasion resistance is not necessarily a measure of how well soils or stains can be removed since some paints have good scrubbability but poor stain cleanability because they are porous. Determine the scrubbability in accordance with Test Method D4213 or D 2486. A control paint should always be tested at the same time because of the variability of the method.
11.8 Slain Removal (Cleanability)--The ability to remove marks satisfactorily without damaging the film is an import tant property of interior finishes. Determine stain removal in accordance with Test Method D 3450,
11.9 Wet Adhesion--It is essential that an interior finish adhere tightly to a given substrate or primer under the wet conditions of washing or scrubbing.
12. Analysis of Paint
12.1 Chemical Analysis--If a specification requires cer tain raw materials or certain components in a given amount, then chemical analysis is required to determine whether the specified materials are present and in what amounts. Anal ysis does not necessarily establish paint quality that can also be greatly affected by manufacturing techniques. Most ASTM analytical methods apply to solvent-based coatings. However, some of them can be adapted for analysis of latex paints.
12.2 Volatile Content--The percent of volatile matter is a
measure of the amount of a liquid coating lost as it dnes t This quantity is not necessarily indicative of the quality ' f coating. It is useful, however, for determining the similarity] of two batches. The referenced method-covers the determi nation of the volatile content by weight of solvent- andl water-reducible coatings. The quantity determined sub-' traded from 100 % gives the nonvolatile content. Determine S volatile content in accordance with Test Method D 2369.
12.3 Volatile Organic Compound (VOC) Content-- eral local jurisdictions in California have adopted air pollu.1 tion controls that severely limit the amount of solvent (Volatile Organic Compound (VOC) content) permitted m architectural coatings, including interior latex gloss and. semigloss paints. Since these paints may contain solvents l such as coalescents and cosolvent wet edge aids, it is essential that these products not exceed the established VOC limits.,. Determine VOC content in accordance with Practice I D 3960.
13. Field Testing
13.1 Although many of the recommended test methods* attempt to simulate conditions under which latex seimgi.i and gloss wall paints are applied, it is not possible to Is accurately simulate all possible conditions. Testing l;.u:. semigloss and gloss wall paints under field conditions jg] recommended for the final evaluation of suitability.

I 'icope
1.1 This test method covers a procedure and apparatus for ilLdting the pull-off strength (commonly referred to as adhesion") of a coating by determining either the greatest
endicular force (in tension) that a surface area can bear fore a plug of material is detached, or whether the surface

Failure will ur along the weakest plane within the system comprised i the test fixture, adhesive coating system, and substrate and be exposed by the fracture surface. This test method simizes tensile stress as compared to the shear stress plied by other methods such as scratch or knife adhesion il TG suits may not be comparable. 1.2 This test method uses a class of apparatus known'as nll-off adhesion testers.2 They are portable and capable of Implying a concentric load and counter load to a single rface so that coatings can be tested even though only one |fde is accessible. Measurements are limited by the strength adhesion bonds between the loading fixture and the ecimen surface or the cohesive strength of the substrate. 1.3 This test can be destructive and spot repairs may be ri'.cssaiy.

2.3 ISO Standard: 4624 Paints and Varnish--Pull-Off Test for Adhesion4
3. Summary of Test Method
3.1 The general pull-off test is performed by securing a
loading fixture (dolly) normal (perpendicular) to the surface
of the coating with an adhesive. After the adhesive is cured, a
testing apparatus is attached to the loading fixture and
aligned to apply tension normal (perpendicular) to the test
surface. The force applied to the loading fixture is then
gradually increased and monitored until either a plug of
coating material is detached, or a specified value is reached.
When a plug of material is detached, the exposed surface
represents the plane of limiting strength within the system.
The nature of the failure is qualified in accordance with the
percent of adhesive and cohesive failures, and' the: actual
interfaces and layers involved. The pull-off strength is
computed based'. on the maximum indicated load, the
instrument calibration data, and the original surface area
stressed (see Fig. 1).
,, .
4. Significance and Use .
4.1 The pull-off strength (commonly referred to as adhe sion) of a coating is an important performance property that has been used in specifications. This test method serves as a means for uniformly preparing and testing coated surfaces, and evaluating and reporting the results. This test method is applicable to any portable apparatus meeting the basic requirements for determining the pull-off strength of a coating.
5. Apparatus
5.1 Adhesion Tester, commercially, available, or compa rable apparatus specific examples of which are listed in Annexes A1 and A2 (see Fig. 1):
5.1.1 Loading Fixtures, having a flat surface on one end that can be adhered to the coating and a means of attach ment to the tester on the other end.
5.1.2 Detaching Assembly (adhesion tester), having a central grip for engaging the fixture.

FIG. 1 Schematic of Pull-Off Adhesion Tester
5.1.3 Base, on the detaching assembly, or an annular
bearing ring if needed for uniformly pressing against the coating surface around the fixture either directly, or by way ofan intermediate bearing ring. A means of aligning the base is needed so that the resultant force is normal to the surface. If shims are required when a bearing ring is employed, place them between the tester base and bearing ring rather than on the coating surface.
5.1.4 Means of moving the grip away from the base in as smooth and continuous a manner as possible so that a torsion free, co-axial (opposing pull of the grip and push of the base along the same axis) force results between them.
5.1.5 Timer, or means of limiting the rate of stress to less than 150 psi/s (1 MPa/s) so that the maximum stress is obtained in less than about 100 s. A timer would be the minimum equipment when used by the operator along with the force indicator in 5.1.6.
5.1.6 Force Indicator and Calibration Information, for determining the actual force delivered to the loading fixture.
5.2 Solvent, or other means for cleaning the loading fixture surface; Finger prints, moisture, and oxides tend to be the primary contaminants.
5.3 Fine Sandpaper, or other means of cleaning the coating that will not alter its integrity by chemical or solvent attack. If any light sanding is anticipated, choose only a very
fine grade abrasive that will not introduce flaws or leave a residue.
5.4 Adhesive, for securing the fixture to the coating that does not affect the coating properties. Two component
epoxies5 and acrylics6 have been found to be the mov versatile.
5.5 Magnetic or Mechanical Clamps, if needed, I p holding the fixture in place while the adhesive cures.
5.6 Cotton Swabs, or other means for removing excess adhesive and defining the adhered area. Any method for removing excess adhesive that damages the surface, such ;x scoring, must generally be avoided since induced surface flaws may cause premature failure of the coating.
5.7 Circular Hole Cutter (optional), to score through to the substrate around thedoading fixture.
6. Test Preparation
6.1 The method for selecting the coating sites to 1: prepared for testing depends upon the objectives of the test1 and agreements between the contracting parties. There are, however, a few physical restrictions imposed by the general method and apparatus. The following requirements apply t' all sites:
6.1.1 The selected test area must be a flat surface lai 1 enough to accommodate the specified number of replicate tests. The surface may have any orientation with reference r gravitational pull. Each test site must be separated by at least ~ the distance needed to accommodate the detaching appa-.;
5 Araldite Adhesive, available from Ciba-Geigy Plastics, Duxford, Cambridge, CB2 4QA, England, Scotch Weld Adhesive I838B/A, available from 3M, Adhesive Coatings amd Sealers Div., 3M Center, St. Paul, MN 55144. and Hysol Epoxy Patch Kit 907, available from Hysol Div., The Dexter Corp., Willow Pass Rd,, Pittsburg, CA 94565, have been found satisfactory for this purpose.
6 Versiloc 201 and 204 with accelerator, available from Lord Corp., Industrial Adhesive Div., 20 J 0 W. Grandview BJvd., P.O. Box 10038, Erie, PA 16514, have been found satisfactory for this purpose.

DUP050297974
Bus. The size of a test site ts essentially that of the secured 'ng fixture. At least three replications are usually re'd in order to statistically characterize the test area..
6.1.2 The selected test areas must also have enough endicular and radial clearance to accommodate the ratus, be flat enough to permit alignment, and be rigid ugh to support the counter force.
6.2 Since the rigidity of the substrate affects pull-off ngth results and is not a controllable test variable in field -urements, some knowledge of the substrate thickness composition should be reported for subsequent analysis .laboratory comparisons. For example, steel substrate of than '/s-in. (3,2-mm) thickness may reduce pull-off ngth results compared to 'A in. (6.4 mm) thick panels.
6.3 Subject to the requirements of 6.1, select representas test areas and clean the surfaces in a manner that will t affect integrity of the coating or leave a residue. Surface sasion may introduce flaws and should generally be
'ed. A light abrasive should only be used if needed to hove loose or weakly adhered surface contaminants. 6.4 Clean the loading fixture surface as indicated by the aratus manufacturer. Failures at the fixture-adhesive 7-rface can often be avoided by treating the fixture surfaces
ordance with an appropriate ASTM standard practice preparing, metal surfaces for, adhesive bonding.
TU' 1--Practices D 2651 and D3933 are typical of well-proven
i.tbods for improving adhesive bond strengths to metal surfaces.
15 Mix the adhesive 'in accordance with the adhesive lufacturer's recommendations, applying the adhesive reen the fixture and the surface to be tested using a %iod preferred by the adhesion-tester manufacturer. Carey remove the excess adhesive from around the fixture.
-VE . 2: Caution--Movement, especially twisting, can cause tiny
les to coalesce into large holidays that constitute stress /ntmuities during testing.
i|;6 Based on the adhesive manufacturer's recommenda*hs and the anticipated environmental conditions, allow ough time for the adhesive to set up and reach the
mmended cure. During the adhesive set and early cure a constant contact pressure should be maintained on
-fixture. Magnetic or mechanical clamping systems work 1, but systems relying on tack, such as masking tape.
Id be used with care to ensure that they do not relax time and allow air to intrude between the fixture and Test area. i|.7 Scoring around the fixture violates the fundamental |situ test criterion that an unaltered coating be tested. If 'ng around the test surface is employed, extreme care is ired to prevent micro-cracking in the coating. Such !cks may cause failures at diminished strengths. Scored pples constitute a different test, and this procedure should fclearly reported with the results. 6.8 Note the approximate temperature and relative flu idity during the time of test.
lest Procedure
7.1 Select an adhesion-tester with a detaching assembly ing a force calibration spanning the range of expected lies along with its compatible loading fixture. Mid-range surements are usually the best, but before proceeding,
read the manufacturer's operating instructions. 7.2 If a bearing ring or comparable device (5.1.3) is to be
used, place it concentrically around the loading fixture on the coating surface.
7.3 Carefully connect the central grip of the detaching assembly to the loading fixture without bumping, bending, or otherwise prestressing the sample and connect the de taching assembly to its control mechanism, if necessary. For nonhorizontal surfaces, the detaching assembly should be manually supported so that its weight does not contribute to the force exerted in the test.
7.4 Align the device according to the manufacturer's instructions and set the force indicator to zero.
NWX' 3: Caution-- Proper alignment is critical. If shims are needed
for fixed alignment devices, report the manner in which used.
7.5 Increase the load to the fixture in as smooth and continuous a manner as possible, at a rate of less than 150 psi/s (1 MPa/s) so that failure occurs, or the maximum stress is reached in about 100 s or less.
7.6 Record the force attained at failure or the maximum force applied.
7.7 If a plug of material is detached, label and store the fixture for qualification of the failed surface in accordance with the procedure in 8.3.
7.8 Report any departures from the procedure such as possible misalignment, hesitations in the force application, etc.
8. Calculation and Interpretation of Results
8.1 Use the instrument calibration factors to convert the indicated force for each test into the actual force applied in units of pounds-force. (1 N = 0.1 kgf).
8.2 Compute the relative stress applied to each coating sample as follows:
X = AF/d2r
where: X = greatest mean pull-off-stress applied during a pass/fail
test, or the pull-off strength achieved at failure. Both have .units of psi (MPa = 1 N/mm2). F = highest force applied to the test surface as determined in procedure in 8.1, and d = equivalent diameter of the original surface area stressed having units of inches (or millimetres). This is usually equal to the diameter of the loading fixture.
8.3 For all tests to failure, estimate the percent ofadhesive and cohesive failures in accordance to their respective areas and location within the test system comprised ofcoating and adhesive layers. A convenient scheme that describes the total test system is outlined in procedures in 8.3.1 through 8.3.3. (See ISO 4624.)
8.3.1 Describe the specimen as substrate A, upon which successive coating layers B, C, D, etc., have been applied, including the adhesive, Y, that secures the fixture, Z, to the top coat.
8.3.2 Designate cohesive failures by the layers within which they occur as B, C, etc., and the percent of each.
8.3.3 Designate adhesive failures by the interfaces at which they occur as A/B, B/C, C/D, etc., and the percent of each.
8.4 Erratic errors should be dropped. Unpredictable errors
793
DUP050297975
D 4541
may result if alignment of the apparatus is not normal to the surface, from poor definition of the area stressed due to improper preparation of the adhesive, poorly defined glue lines and boundaries, holidays in the adhesive caused by voids, inclusions, improperly prepared surfaces, or sliding or twisting the fixture during the initial cure. Scratched or scored samples may contain stress concentrations leading to premature fractures. These should be retested at adjacent areas.
8.5 Further information relative to the interpretation of the test results is given in Appendix Al.
9. Report
9.1 Report the following information: 9.1.1 Brief description of the general nature of the test, such as, field or laboratory testing of the general type of coating as applied to a given substrate, etc. 9.1.2 Temperature and relative humidity and any other pertinent environmental conditions during the test period. 9.1.3 Apparatus used, fixed or self-aligning, which in cludes: apparatus manufacturer and model numbers, loading fixture type and dimensions, and bearing ring type and dimensions. 9.1.4 Description of the test system, if possible, by the indexing scheme outlined in 8.3 including: product identity and generic type for each coat and any other information supplied, the substrate identity (thickness, type, orientation, etc.), and the adhesive used. 9.1.5 Test results.
9.1.5.1 Date, test location, testing agent.
9.1.5.2 For pass/fail tests, stress applied along with thel
result, for example, pass or fail and note the plane of am,1
failure (see ANSI N512).
y'
9.1.5.3 For tests to failure, all values computed in (j.J
jalong with the nature and location of the failures as specified
in 8.3, or, if only the average strength is required, report it
along with the statistics.
9.1.5.4 If corrections of the results have been made, or if
certain values have been omitted such as the lowest cit '.
highest values or others, reasons for the adjustments and
criteria used.
9.1.5.5 For any test where scoring was employed, indicate
it by placing a footnote superscript beside each data point
affected and a footnote to that effect at the bottom of each!
page on which such data appears. Note any other deviations
from the procedure.
10. Precision and Bias
10. i The precision and bias is primarily dependent upon the accuracy of the force measurement, the alignment of the device, and the care exercised in preparation and testing. "
10.2 Since no standard for pull-off strength ofcoatings ti||| been developed prior to this test method, precision and bi| statements will be developed in round-robin testing.

XI. STRESS CALCULATION
XI. 1 The stress computed in 8.2 is equal to the uniform uH-off strength of the analogous rigid coating system ifthe
l ilied force is distributed uniformly over the critical locus the instant of failure. For any given continuous stress
'bution where the peak-to-mean stress ratio is known,
uniform pull-off strength may be approximated as;

peak-to-mean stress ratio.
important to note that a difference between these
-off strengths does not necessarily constitute an error;
rather the in-situ measurement simply reflects the actual character of the applied coating system with respect to the analogous "ideal" rigid system.
XI.2 An error is introduced if the alignment of the apparatus is not normal to the surface. An approximate correction by the peak-to-mean stress ratio is:
R = (l + 0.14 az/d),
where: z = distance from the surface to the first gimbal or the
point at which the force and counter force are gener ated by the action of the driving mechanism, in. (mm), d = 'diameter of the loading fixture, in. (mm), a = angle of misalignment,' degrees (less than 5), and R = maximum pekk-to-mean stress ratio for the misaligned rigid system.

The pooled between-laboratories standard deviation was 0.22 % absolute with 21 df. One laboratory's results for one day were discarded because the duplicates differed significantly and another laboratory's results for one day because the range differed significantly from all other ranges for Coating 1 and a third laboratory's results for one day because it differed significantly from the other day's results and those from all other laboratories for Coating 2.

12. Procedure
12.1 Determine the dry weight of two weighing bottles
with caps. In accordance with Table 1 select the appropriate
specimen weight and place the approximate! amount of
recovered pigment in each weighing bottle.
12.2 Dry the specimens in the open weighing bottles for 2
h at 105C. Cool in a desiccator. After cooling, cap the
weighing bottles and weigh as rapidly as possible.
12.3 Transfer the dry specimens to 500-mL wide-mouth
Erlenmeyer flasks. Reweigh bottles and caps and record
weights ofspecimens transferred (W4 in equation in 13.1 and
13.2).
12.4 To the 500-mL flasks, which now contain the
specimens, add 8 g 0.001 g of (NH4)2S04, 50 mL of
concentrated H2S04 and 5 drops of concentrated HN03.
Mix well by swirling the flasks. Heat on a hot plate until
dense white fumes are evolved. Continue heating over a hot
flame until solutions are complete (usually requires not more
than 5 min of boiling), or until it is apparent that the residues
are composed of SiOz or siliceous matter. Cool and add 100
mL of water with extreme caution.

3. Summary of Test Method 3.1 A specimen of a well-agitated electrocoat bath is
placed in a stirrer-equipped container and the pH measured with a pH meter and associated glass and reference elec trodes.
4. Significance and Use 4.1 The pH is the measure of the free hydrogen ion
concentration of a sample, and it indicates whether an electrocoat bath is acidic, neutral, or basic. Since pH measurements of good precision are made in aqueous solutions, it is suggested that the pH measurements of electrocoat baths are only semi-quantitative, and therefore such measurements should be referred to as apparent pH measurements.
4.2 The pH of electrocoat paints is used for research, production, and quality control or electrocoat bath process control.

Standard Practice for Testing Water Resistance of Coatings Using Controlled Condensation1
This standard is issued under the fixed designation D 4585; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.
fl N]^' --Paragraph 7.3 was corrected editorially in June 1988.
1. Scope
1.1 This practice covers basic principles and operating procedures for testing water resistance of coatings using controlled condensation. Condensation is produced by ex posing one surface of a coated specimen to a heated, saturated mixture of air and water vapor, while the reverse side of the specimen is exposed to the cooling effect of room temperature air. This practice is derived from research of.thie Cleveland Society for Coatings Technology.2
1.2 This practice is limited to the methods of obtaining, measuring, and controlling conditions and procedures of controlled condensatidri tests. It does not specify specimen preparation, specific test conditions, or evaluation of results.
N_`' 1--Alternative practices for testing water resistance of coatings include Practices D 870, D 1735, and D 2247.
1.3 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Practice
3.1 Water vapor is generated by heating a pan of water aft
the bottom of the test chamber. The specimens form the roof
or walls of the test chamber so that the back sides of the i
specimens are exposed to the cooling effects of root#*!
temperature air. The resulting heat transfer causes vapor topi
condense on the test specimens as liquid water saturated witlf|P
air.
3.2 The temperature and amount of condensate forminfll
on the specimens is controlled by the test temperature and1
the room temperature. The test specimens are inclined so'
that condensate runs off the test surface by gravity and is
replaced by fresh condensate in a continuous process during'
the condensate cycle.
3.3 Exposure conditions are varied by selecting: (a) the
temperature of the test, (b) the duration of the test, and (.
periodic drying of the specimens. Testing may be conducted , j
at temperatures from 100 to 180"F (38 to 82"C). Any effect||
such as color change, blistering, loss of adhesion, softening, :]!
or embrittlement are observed and reported.

4. Significance and Use
4.1 Water can cause degradation of coatings, so knowl edge of how a coating resists water is helpful in predicting its service life. Failure in a condensation test may be caused by a number of factors including a deficiency in the coating itself, contamination of the substrate, or inadequate surface preparation. The test is therefore useful for evaluating

7.1 Fill the water pan tb a depth of approximately 1 in. (25 mm) with water. The quality ofthe water in the pan does not affect the test since the evaporation and condensation process yields distilled water, but the use of tap water can result in the accumulation of residues in the water pan.
7.2 Fill all spaces in the specimen holder rack with specimens or corrosion-resistant blank panels. Mount coated metal panels with the coating to be tested facing the inside of the chamber. Coated wood specimens may be mounted in the same way.
7.2.1 Blister tests to simulate the effects of water vapor migration from inside a frame house are mounted with the uncoated side of the wood specimen facing the inside of the test chamber.
7.2.2 Seal all cracks between specimens and holes in specimens with tape or metal strips. Condensate may seal small openings but cracks larger than 0.04 in. (1 mm) and holes larger than 0.08 in. (2 mm) in diameter can cause water vapor loss and local temperature variation.
7.3 Adjust the thermostat to maintain the desired temper ature of the saturated air and water vapor mixture. Vapor temperatures of 100, 120, or 140F (38, 49, or 60C) are suggested. Other temperatures may be used provided that the
805
DUP050297987
# D 4585
temperature is reported in conformance with Section 8. To ensure adequate condensation, maintain a 20F (HC) temperature differential between the room and the vapor.
7.4 Operate the chamber continuously unless otherwise specified or agreed. The removal of specimens for inspec tions during operation is permitted. When removing a specimen for inspection, replace it with a blank so that the test conditions are not altered.
7.5 Cyclic operation with alternating periods of condensa tion and drying may be used. Automatic drying requires the apparatus described in 5.6. For manual drying of specimens, remove them from the apparatus. Drying periods should be at least 4 h long.
7.6 Conclude the test after a specified period of time or after effects from exposure to water are noted.
7.7 Remove specimens at the conclusion of the test; Do not leave the; specimens in the apparatus at the conclusion of the test as the specimens can remain wet for hours, or even days, when the apparatus is turned off.
7.8 Wipe the test specimens dry. Rate specimens for changes in color, blistering, etc. Evaluate specimens no less than 5 min and no more than 10 min after removal from test, as the effects from water exposure can change within a short time. Remove only as many specimens as can be rated within the specified time.
Nef' 4--The 0 to 10 scale described in ASTM STP 500s >s Preferred
for rating. Relevant procedures for evaluating water effects are describM in Methods D 610 and D 2616, and Test Methods D 714, D 3359 a, D 3363.
7.8.1 If possible, rate the specimens again after they have been removed from the test for a recovery period long enough that moisture absorbed within the specimen dries out and the specimens reach moisture equilibrium with room : air. A recovery period from 12 to 24 h is generally sufficient. ! The post-recovery rating allows evaluation of the permanent effects of the exposure as distinct from the transient effects, and is especially important for evaluation of color and glos,

3. Significance and Use >'.
3.1 Organic coatings on exterior exposure are subjected to attack by degrading elements of the weather, particularly ultraviolet light, oxygen, and water. This practice may be used for evaluating the behavior of films exposed in appa ratus that produces ultraviolet radiation, high temperatures, and water condensation on the films. This apparatus is used to make an early materials comparison of the exterior exposure quality of paints. However, light sources, such as the fluorescent UV lamp, that emit a significant amount of radiation at wavelengths shorter than those in natural sunlight, may cause results that lead to unrealistic evalua tions of weathering properties.
3.2 As no single light exposure apparatus, with or without water, can be specified as a direct simulation of natural exposure, this practice does not imply expressly, or other wise, a specific correlation with outdoor exposure. It has, however, been useful in many instances.
3.3 Since climatic conditions vary with respect to time.

geography, and topography, it may be expected that the effects of natural exposure will vary accordingly. All mate rials are not affected equally by the same environment. Results obtained by use of this practice should not be represented as equivalent to those of any outdoor weathering test unless the degree of quantitative correlation has been established for the material in question.
3.4 Variations in results may be expected when operating
conditions among similar type instruments vary within
accepted limits of this standard procedure.
4. Test Specimens
4.1 Unless otherwise agreed upon, choose panels that meet the applicable base panel requirements specified in Standards D 358, D609, D 1730, D 1731, D 1732, or D 2092, Select panel sizes suitable for exhibiting the failure mode to be observed.
4.2 Apply the coatings to flat panels with the base panel material, method of application, coating system, film thick ness, and method of drying consistent with the anticipated end use, or as mutually agreed upon between the producer and the user. If it's not possible to testflat samples, you may need to take special precautions to ensure that {!) the sample holders seal behind the samples so that the water vapor does not escape from the test chamber, and (2) the closest part of the samples to the UV lamps is at the 50-mm distance specified in Practice G 53. If part of the sample is closer to the lamps, it will be subject to more intense UV exposure.
4.3 Unless otherwise agreed upon, coat test panels in accordance with Test Methods D 823 and measure the film thickness in accordance with an appropriate procedure selected from Test Methods D 1005, D 1186, or D 1400. Nondestructive methods arc preferred because panels so measured do not need to be repaired.
4.4 Unless otherwise specified, before exposing coated panels in the apparatus, condition them at 73.5 3.5? (23 2C) and 50 5 % relative humidity for one of the following periods in accordance with the type of coating:
Baked coatings Radiation-cured coatings All other coatings

3. Significance and Use
3.1 Microbial growth is a major cause ofdiscoloration and deterioration of paint films. This guide describes techniques used to distinguish fungi and algae from other surface contaminants.
3.2 Repainting a surface contaminated with fungi or algae generally causes more rapid infestation of the new paint than repainting a surface from which fungal or algal growth has been removed. This guide describes methods for removing fungal or algal growth prior to repainting.
4. Reagents
4.1 Sodium Hypochlorite, approximately 5 % aqueous (NaOCl) as commercial household bleach. Because sodium hypochlorite decomposes on exposure to heat and sunlight and becomes ineffective, use only fresh material. See Method D 2022 for methods of sampling and chemical analysis.

5. Procedures
5.1 Determining the Presence of Fungal or Algal Growth on Paint:
5.1.1 Chemical--Apply a drop of 5 % aqueous sodiu r. hypochlorite solution (common household bleach) to the area suspected of being contaminated with fungal or algal growth. Fungal or algal discoloration will normally bleach within 60 s. Discoloration that does not bleach is probably dirt. For further confirmation do visual and subculture tests.
5.1.2 The following procedures should preferably be used by persons who have had basic microbiological training:
5.1.2.1 Visual--Examine the surface using magnification from 10 to I00X to distinguish among fungal, algal, or dirt disfigurement in accordance with Test Method D 3274.
5.1.2.2 Subculture--Apply a prepared petri dish con taining a raised convex surface of nutrient agar culture medium4 directly to the surface to be sampled and exert moderate pressure. Replace the cover and incubate for least 72 h at 95"F (35C). Examine the agar surface visualc. as in 5.1.2.1.
Nkl' t--The culture medium must contain the nutrients necessary
for growth of algae and fungi.
5.2 Removal ofFungal and Algal Growth on Paint: 5.2.1 Wash the surface with a solution of approximately 5 % trisodium phosphate in water or a solution at approxi mately 2 % laundry detergent in water. 5.2.2 Thoroughly rinse the surface with water to remove residual trisodium phosphate or detergent. 5.2.3 Wash the surface with a solution of 1 part by volume of sodium hypochlorite 5 % aqueous solution and 3 parts by volume of water.
Nmn' 2--The solution should be allowed to remain on the surface
from 10 to 15 min.
Nop' 3--The sodium hypochlorite solution and the 2 % laundry
detergent solution may be combined 1:1 by volume in one treatment t desired.
5.2.4 Thoroughly rinse the surface with water to remove residual sodium hypochlorite.
5.2.5 If agreed upon by the parties involved, reinspect the surface in accordance with 5.1 to ensure that there has been adequate removal. Refer to the coating manufacturerliterature for recommended drying time before recoating.

i Designation: D 4707 - 87 (Reapproved 1991}
Standard Test Method for Measuring Pairit Spatter Resistance to Roller Application1
This standard is issued under the fixed designation D 4707; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year oflastreapproval. A superscript epsilon (t) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers the determination of the tendency of a paint to spatter when applied with a paint roller to a substrate.
1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility ofthe user of this standard to establish appro priate safety and heath practices and determine the applica bility ofregulatory limitations prior to use.
2. Referenced Documents
2.1 ASTM Standards: D 3924 Specification for Standard Environment for Con-'
ditioning and Testing Paint, Varnish, Lacquer, and Related Materials2 D 3925 Practice for Sampling Liquid Paints and Related Pigmented Coatings2 2.2 Other Document: Photographic Standards of Paint Roller Spatter3
3. Summary of Test Method
3.1 The test paint is applied to a black plastic panel by draw-down. The coated plastic panel is immediately mounted on an essentially vertical surface above a sheet of paper used to catch any spatter. A specially designed notched spool roller (see 5.1) is rolled through the film following a defined procedure, tending to generate spatter. Any spatter falls upon the spatter catch paper, and after drying is rated against the photographic standards.
4. Significance and Use
4.1 Paint spatter generated by roller application is depen dent on the properties of both the paint being applied and the paint roller cover used for the application. To eliminate the influence of the paint roller cover as a variable, and thus restrict the spatter-inducing variable to the paint under test only, the paint roller cover is replaced by a standard notched spool roller to generate spatter by a mechanism that simu lates that of a paint-applying roller cover.
4.2 Although most of the development work to establish this test method was undertaken using latex paints, sufficient
work was also done to show its applicability to solventreducible paints.
4.3 Tests during the development of this test method showed that the spattering properties of paints, like other physical properties, may in time change. Therefore, ihj results ofthis test are valid only for the time when the test is run.

Into the well formed by the film caster, pour sufficient paint so that the well is filled from jrner to comer. Draw down the paint the full length of the 'plastic panel, until the film caster is fully beyond the tredge. The rate of application should be fairly slow, 3 to 4
rom end to end, to prevent pinholes or holidays in the t film. .3 Immediately upon completion of the draw-down, emove the black plastic panel from the glass plate, keeping masking tape intact, and tape, with the long direction rtical, to a surface that is vertical or nearly vertical (within tpf vertical, top sloping away from the operator) with the ttom of the black plastic panel about 1 in. (25 mm) above e laboratory bench or table (Fig. 2). It is desirable that the urface under the black plastic panel be firm but with a little .silience. A backing of 'A-in. (6-mm) thick pasted iberboard7 is ideal as very hard surfaces make proper rfomtance of the test difficult. Center the spatter catch Iper on the laboratory bench or table under the black lastic panel.

8.4 Using the clean, notched spool roller, start in one of the upper comers and roll downward and upward through the paint film. Always keep,the notched spool in contact with the black plastic panel, fiot removing the roller from the film when changing directions. Make ten passes in each direction (20 passes total), 15 Vi in. (380 15 mm) per pass, progressively moving sideways from one edge of the film to the other (Fig. 3). Each pass should coincide with a beat of the metronome and the motion should be contin uous, not jerky. Try to emulate the motion of the metro nome, using the metronome for accurate timing (practice the motion with the metronome to gain the necessary rhythm and timing), since the speed of the rolling of the notched spool roller through the paint film has been found to be the only variable significantly affecting the results of the test. Make sure that all four flanges ofthe notched spool roller are within the draw-down area at all times. Use sufficient pressure to maintain constant contact between the notched spool roller and the black plastic panel. Note that as long as constant contact is maintained, pressure variations have not been found to noticeably affect the results.
8.5 Remove the spatter catch paper and lay it in a suitable place to dry.
8.6 Repeat the test with a second plastic pane! after cleaning the apparatus.

9.2 Using the photographic standards numbered I, 3,5,7, and 9 for comparison, rate each test with a number from 0 (low spatter resistance) to 10 (no spatter), interpolating as needed for ratings 2, 4, 6, and 8.

from about 4 to 10. A change in pH during storage may cate poor stability or a change in properties of a
reducible coaling. Determine pH in accordance with Method E 70. jj.9 Freeze-Thaw Resistance--Water-reducible coatings "|iy be subjected to freezing conditions during shipping and ! rage. Suitably stabilized paints will resist several cycles of ng and thawing without showing deleterious changes, referenced method covers the determination of the it to which water-reducible coatings retain their original itency and freedom from lumps when subjected to ng and subsequent thawing. Determine freeze-thaw nee in accordance with.Test Method D 2243. 10 Package Stability--Since liquid coatings cannot nor-
be used immediately after manufacture, they must in stable in the package for some time. The referenced method covers the change in consistency and ip certain ated properties that may take place in packaged waterlucibfe coatings when stored at a temperature above room imperature. Determine package stability in accordance with test Method D 1849, at a temperature and, for a period'of le agreed upon by the purchaser and the seller.
Nyz' --Although there is no ASTM or Federal test method for
ifermining gassing during normal storage, special containers may he l|essary to vent any spontaneous pressure biiildup.
9.11 Microorganism Resistance--Microorganisms in waifrreducible coatings can cause gassing, putrefaction or fomentation odors, and loss of vicosity. Determine if the Tpid coating contains living bacteria and if it is resistant to Sack by bacteria in, accordance with Test Method D2574. 9.12 Surface Tension--Although there is no ASTM or tederal test method for determining surface tension ofliquid Tarings, this is an important property of a water-reducible to or coating. If surface tension is top high, poor pigment id substrate wetting may occur, leading tq cratering, low loss, or other surface defects. The most common methods | measuring the surface tensions of coatings probably are B ring pull method and drop weight method.. For a ^apprehensive discussion of these and other aspects of Surface tension, see Paint Flow and Pigment Dispersion.`6 9.13 Flash Point--Nearly all water-borne coatings, ace capable of sustaining combustion, but many do. contain volatile solvents whose vapors can ignite if near open flame, tecause they do give flash points, water-borne coatings must
tested for flash point temperature to conform with many government regulations concerning transportation, labeling, packaging, etc. Determine flash point in accordance with ,;{est Methods D 56, D 93 or D 3278. }>l9.14. Conductivity--Conductivity, is an important factor It the application of some water-borne coatings. Test 'Methods available for determining conductivity are D 1125 ^"'specifically Methods A and B) and D 4399.

by the producer and the user. Prepare panels for testing the coating in accordance with Test Methods D 609, D 1730, DI731, D 1732, D2201, or D2092. The preparation of plastics for paint testing is covered in Practice D 3002.
10.2 Application Properties--Determine the ease with which the liquid coating can be applied to various surfaces with brush, spray, or other application equipment. Applica tion properties are generally compared to a standard, or described by requirements in a product specification. Appli cation properties are related to such characteristics as kine matic viscosity, non-Newtonian rheology, surface tension, shear sensitivity, micelle stability, electrical resistivity, ero sion abrasiveness, conductivity, heat capacity, and corrosive ness.
10.2.1 Sprayed Film Application--Liquid coatings can be applied by spray. Determine the spray application properties in accordance with Method 2131.1 of Federal Test Method Standard No. 141. The rnethod can be modified tq include application by airless spray equipment.
10.2.2 Drying Properties---The drying time of water-re ducible coatings is important in determining when, the applied coatings can be handled or packed. Also, inadequate drying of the film may result in'poor filth and poor appearance and, if used on an exterior surface, rain, dew, or snow may cause a nonuniform appearance. Determine drying time in accordance with Test Method D 1640, or as agreed upon by producer of user.
10.3 Leveling Properties--Leveling is an important factor When uniform surfaces are to be produced, as it affects hiding and appearance. The referenced methods cover the labora tory determination of the relative leveling characteristics of liquid coatifigs. Determine the leveling Characteristics in accordance with Test Method D 4062. Measure wet film thickness in accordance with Test Method D 1212.
10.4 Producing Films of Uniform Thickness--The fol lowing test method covers thepreparation ofvarious films of uniform thickness essential in conducting tests. Prepare films in accordance with Test Methods D 823.
10.5 Low Temperature Coalescence of Paints--A test method to determine how well the latex particles to coating will fuse together or coalesce to form a continous .film at low temperature is described in Test. Method D:3793. A test for the minimum film formation temperature is described in
Test Method D 2354. 10.6 Touch-Up--For many coating,systems it is impor
tant to be able to repair damage sustained during production, delivery, or after delivery. A - coating can be tested by applying it with a small nylon bristle brush or air brush to a small section of a panel previously coated with it. When the touch-up area has dried, it is examined to see if it differs significantly from the initial coating. Determine the ability to touch up the coating in accordance with Test Method D 3928. Test the adhesion of the original and touch-up areas in accordance with Test Methods D 3359 or other agreedupon test method.
11. Appearance of Dry Film
11.1 Color--The color of a water-reducible coating may be specified independently or as the color-difference with respect to another color that is usually the standard. Visual and instrumental methods are both applicable. An opaque

film is preferred that may be prepared by making one or more applications of water-reducible coating onto a black and white substrate until the substrate is completely ob scured. Each application should be performed in a normal manner with respect to application method, drying, and film thickness.
11.1.1 Color Differences by Visual Evaluation--Visual comparison of color is fast and often acceptable although numerical values are not obtained. The referenced standard covers the spectral, photometric, and geometric characteris tics of light source, illuminating and viewing conditions, size of specimens, and general procedures to be used in the visual evaluation of color differences of opaque materials. Deter mine color difference by visual evaluation in accordance with Practice D 1729 or Test Method D 2616.
11.1.2 Coldr Differences of Opaque Material by Instru mental Evaluation--Color difference between a product and the standard can be measured by an instrument Generally, the tolerance is agreed upon by the purchaser and the seller and may also be required if a product specification is involved. Color instruments provide numerical values that can be subsequently compared to later measurements. The referenced method covers the instrumental determination of small color differences observable in daylight illumination between nonfluorescent, nonmetameric, opaque surfaces
such as coated specimens. If metamerism is suspected, visual evaluation (10,1.1) should be used to verify the results. Make instrumental measurement of color difference in accordance with Method D 2244, Tolerances are discussed in Recom mended Practice D 3134.
11.1.3 Color Description by Visual Evaluation--In some cases it is necessary to specify or identify a color instead of a color difference from some standard. Various color atlases are available, the most common being the Munsell System. Describe or identify the Mtfnsell color in accordance with
Method D 1535.
11.1.4 Color Description by Instrumental Evaluation-- Instrumental measurements involve the determination of CIE tristimulus values, X, Y, and Z, from which other color coordinates such as L*. a*, b*, or L, a, b values may be calculated or obtained directly with some instruments. Describe or identify in accordance with Method D 2244.
11.2 Gloss--Water-reducible coatings vary in gloss and the end use determines whether the gloss should be high, semi-gloss, eggshell, or flat. Determine the gloss in accord ance with Test Method D 523 using 20, 60, or 85geometry as appropriate.
11.3 Hiding Power (Dry Opacity)--Hiding power is the measure of the ability of a paint to hide the substrate. It is, however, dependent upon uniform film thickness which is influenced by flow and leveling. Test Method D 344 is a practical test in which paint is applied with a brush, film thickness is approximately measured, and opacity is evalu ated visually as compared to a standard paint. Results are affected by flow and leveling application properties of the paint. Test Method D2805 is considered to be a more precise and accurate test that does not need a material paint standard. Paint is applied with an applicator bar to minimize the effects of flow and leveling, film thickness is rigorously measured, and opacity is instrumentally evaluated. Deter
mine hiding power in accordance with Test Methods D 344 or D 2805.

11. Precision and Bias
11.1 Fredsion:. 11.1.1 Test Method A--Heatset Systems. An interlabora tory8 study was conducted in which one operator in each of five laboratories tested in duplicate on each of two days four heatset printing inks, of which two were low NVM (about 50 %) and two were high NVM (about 60 %). The roundrobin data were analyzed according to Practice E 691. There were no outliers. The within-laboratory pooled standard deviation was found to be 0.44 % absolute at 12 degrees of freedom, and the between-laboratories pooled standard devi ation was 2.0 % absolute at 16 degrees of freedom. Based on these standard deviations, the following criteria should be used for judging the acceptability of results at the 95 % confidence level: 11 A.].{.Repeatability--Two results, each the mean of two runs obtained by one operator, should be considered suspect if they differ by more than 1.2 % absolute. 11.1.1.2 Reproducibility--Two results, each the mean of two runs obtained by operators in different laboratories, should be considered suspect if they differ by more than 5.7 % absolute. 11.1.2 Test Method B--Liquid Ink Systems. See Precision section of Test Method D 2369. 11.2 Bias--In the interlaboratory study of heatset inks described in 11.1, the mean values for NVM agreed with the calculated values within 1 % absolute.

3.1 double rub--a back-and-forth motion over the test area of approximately 2 in. (50 mm).
4. Significance and Use
4.1 Ethyl silicate zinc-rich primers cure by the reaction of the vehicle with moisture thereby providing a binder. As relative humidity and temperature vary during the day, so does the rate of cure. A certain minimum degree of cure is necessary prior to topcoating. It has been shown that the degree of cure of ethyl silicate zinc-rich primers can be measured by the chemical changes occurring using diffuse reflectance infrared spectroscopy.2 This solvent rub test has been shown to correlate well with the infrared spectroscopic results of two-component ethyl silicate inorganic zinc sys tems.

are taken into account in the calculation of results.
4. Significance and Use 4.1 Titanium dioxide pigments are components with hign
refractive index that significantly influence the opacity color, durability, and other properties of coatings. This test method for detepnining titanium dioxide content is quicker and easier to use than Test Methods D 1394, a wet chemic il analysis method for pigments. It is conveniently applicable to single samples and to large numbers of samples. Only a single relatively stable reagent used to prepare standards a.iJ paints under test need be stored. Drawdown specimens used as standards, once prepared, can be stored indefinitely air used repeatedly.
5. Apparatus 5.1 X-ray Fluorescence Spectrometer, suitable for mea
surement of the baseline corrected intensity of the K lint., of titanium and of bromine. For spectrometers equipp i with a tungsten or chromium target and a lithium fluoride (200) analyzing crystal, these lines are observed at 20 an ks of 86.09 and 29.97, respectively.
N' 1--Follow the recommendations of the manufacturer of the ,
instrument used. Use operating conditions that ensure that the count rate for bromine and titanium are within the linear response range ofthe detector. Although the base operating conditions and count rate may htr different tor different instruments, these differences will not affect tits outcome of the analysis.

front the drawdown on the plastic sheet a disk of a size appropriate for the specimen holder of the spectrometer.
8,3 Determine the percent nonvolatile content of each paint at 110C in accordance with Test Method D 2369 if the information is not already available.
9. Procedure
9.1 Turn, on the spectrometer and allow it to stabilize thoroughly before beginning collection of results. With the aid of the manufacturer's literature, select spectrometer settings to permit measurement of the intensity of the Kopeaks of titanium and bromine. For instruments equipped with an X-ray tube with a tungsten or chromium target, the' settings prescribed in Table 1 may be used as guidelines (Note 1).
9.2 Place the disk in the specimen holder in such a way that the coated side of the sheet is turned toward the incident X-rays. Before measuring the specimens, record the back ground spectrum in the ranges of the Ka peaks of titanium and bromine, including at least 10 on each side. Check the spectra for the presence of interfering peaks and select for each peak an angle for background measurement where interference is at a minimum,
9.3 At the selected angles measure the background inten sities and the intensities of the Kcr peaks of titanium and bromine in counts per second (c/s). Determine the net intensity, c/s, of each peak by subtracting the background count from the peak count.

two samples of latex house paint and two samples of
solvent-reducible house paint. The mean weight percent

respectively, 3.64, 19.1, 7.44, and 15.8 %. The pooled
within-laboratory coefficient of variation was 2.39 % with 19:
degrees of freedom' and the pooled between-laboratories
coefficient of variation 4.47 % with 15 degrees of freedom,
after discarding one duplicate value from one laboratory
because the range differed significantly from all other dupli
cate ranges for paint sample Number 2. Based on these
coefficients of variation, the following criteria should be used'
forjudging the acceptability ofresults at the 95 % confidence
level:
11.1.1 Repeatability--Two results, each the mean of du- '
plicate determinations, obtained by the same operator on
different days should be considered suspect if they differ by-
more than 7.08 ^ relative.
11.1.2 Reproducibility--Two results, each the mean of
duplicate determinations, obtained by operators in different
laboratories should be considered suspect if they differ by
more than 13,5 % relative.

linings Applied ter conductive substrate^. 3.1.5 test voltage---that electrical voltage established
which will allow a discontinuity at the thickest lining location site to be tested, but which will not damage the lining. The test voltage must always be set well below the dielectric breakdown strength of the lining. This voltage should normally be recommended by the lining manufac turer. The dielectric breakdown voltage strength of a solid can be determined by Test Method D 149. .
4. Summary of Practice
4.1 This practice: allows for high voltage electrical detec tion of discontinuities in new linings applied to concrete substrates through the utilization of a continuous conductive underlayment applied to the prepared concrete surface prior to the application ofthe nonconductive lining layer(s).
5. Significance and Use
5.1 The electrical conductivity of concrete is primarily influenced by the presence of moisture. Other factors which affect the continuity of concrete include the following:
.5.1.1 Presence of metal rebars, 5.1.2 Cement content and type, 5.1.3 Aggregate types, 5.1.4 Admixtures, 5.1.5 Porosity,, 5.1.6 Above or below grade elevation, 5.1.7 Indoor or outdoor location, 5.1.8 Temperature and humidity, and 5.1.9 Age of concrete. 5.2 The electrical conductivity of concrete itself may be successfully used for high-voltage continuity testing oflinings applied directly with no specific conductive underlayment installed. However, the voltage required to find a disconti nuity may vary greatly from point to point on. the structure. This variance may reduce the test reliability to an unaccept able level.1 5.3 Although the most common conductive underlayments are liquid primers applied by trowel, roller, or spray, and which contain carbon or graphite fillers, others may take the form of the following: 5.3.1 Sheet-applied graphite veils, 5.3.2 Conductive polymers, 5.3.3 Conductive graphite fibers, 5.3.4 Conductive metallic fibers, and 5.3.5 Conductive metallic, screening. 5.4 Liquid-applied conductive underlayments may be desirable as they can serve to address imperfections in the concrete surface and provide a better base for which to apply the. lining.

5.5 This practice is intended for use with new linings applied to concrete substrates. It may also be applicable for linings previously tested by this practice and subsequently placed in service. However, consideration must be given to potential changes to the electrical properties of the conduc tive and nonconductive layers comprising the system.
5.6 The user may consider this practice when perform ance requirements of the lining in a specified chemical environment requires assurance of a lining free of discontinuities.
5.7 Factors affecting the dielectric properties and test voltage shall be considered. Some factors are the curing time of liquid-applied linings; the possible presence of electrically conductive fillers or solvents, or both; the possible presence of air inclusions or voids; and the compatibility of conduc tive underlayments with the specified lining.
6. Apparatus
6.1 High Voltage Spark Tester--An electrical detector with a voltage rating in excess of 900 V. The detector is to consist of an electrical energy source, an exploring electrode, a ground connection, and ground wire. The detector shall be equipped with a visual or audible indicator, or both.
6.1.1 Electrical Energy Source--Either a-c, d-c, or pul sating d-c type with the appropriate test voltage.
6.1.2 Exploring Electrode--The full length shall be ca pable of maintaining continuous contact with the surface being inspected.
6.1.3 Ground Wire, stranded 14 to 16 gage copper wire. 6.1.4 Visual or Audible Indicators, or both, to signal a closed electrical circuit. Such signals shall be essential for testing the underlayment for electrical conductivity and for exposing discontinuities innhe lining after it has been applied.
7. Hazards
7.1 Solvents retained in the applied conductive underlayment may create an explosive environment as well as produce erroneous results.8
8. Conductive Underlayments
8.1 The conductive underlayment shall not rely on the concrete substrate's electrical properties.
8.2 The specified lining shall be compatible with the specified conductive underlayment.
8.3 Application: 8.3.1 The finished conductive underlayment surface shall be relatively smooth. The conductive underlayment shall be considered part of the lining system and must be installed in accordance with the manufacturer's latest published instruc tions. 8.3.2 Visually verify that the conductive underlayment covers the entire area to be lined. Breaks at expansion joints and construction joints are allowable unless otherwise speci fied. 8.4 Verification of Underlayment Conductivity: 8.4.1 The surface of the applied conductive underlayment shall be clean, dry, free of oil, grease, dirt, or other contaminants and be sufficiently cured in accordance with the manufacturer's latest published instructions at the time
the high-voltage spark testing is performed. (Warning--See Section 7.)
8.4.2 Verify the operation of the high-voltage test instru ment in accordance with Section 9.
8.4.3 Adjust the high-voltage test instrument in accord ance with Section 10.
8.4.4 Ground the test instrument to the installed underlayment or other appropriate ground. If electrical isolation across an expansion joint is encountered, the ground wire must be moved to an appropriate ground in the same section being tested.
8.4.5 Place the exploring electrode on a nonconductivi spacer so that an air gap between the surface of tin underlayment and the electrode is equal to the maximum thickness of the lining.
8.4.6 The underlayment is conductive if a spark-over is emitted and the visual or audible indicator, or both, on the test instrument is activated.
8.4.7 Test Sampling. 8.4.7.1 A minimum of four test points shall be used foi the first 100 ft.2 Test points shall be approximately equal!; spaced within the test area. At least one additional test point shall be used for every 500 ft2 thereafter. 8.4.7.2 Test points most distant from the ground connec tion shall be included in the test sampling. 8.4.8 The specified lining shall not be applied until th( conductivity of the underlayment has been verified.
9. Verifying Operation of High-Voltage Spark Tester
9.1 Test electrical source for proper voltage output. 9.2 Follow the equipment manufacturer's operating in structions for verifying the operation of the high voltagetester. 9.3 If the tester fails to signal, it shall be considered defective.
10. Adjustment of High-Voltage Spark Tester for Verifying Conductivity of Underlayment
10.1 Establish the test voltage based on the maximun specified thickness of the nonconductive lining, its dielectric strength, and the lining manufacturer's recommendations.
10.2 Following the equipment manufacturer's instruc tions, set and check the test voltage established in 10.1.
11. Application of the Lining or Coating
11.1 Apply the specified lining in accordance with gov erning specifications.
12. Adjustment of High Voltage Spark Tester for Verifying Conductivity of the Applied Lining
12.1 Select the proper test voltage to provide reliable spark-over to locate a holiday under normal test conditions The voltage selected must jump an air gap equal to the maximum specified dry film thickness of the lining being tested and not arc through the lining at the minimun specified dry film thickness.
12.2 Adjust the tester to the test voltage established in 12.1 as follows:
12.2.1 Connect a high-voltage voltmeter or a spark-gap calibrator between the electrode and the ground wire.
12.2.2 Switch the detector to the ON position.

steel cubes are then immediately placed onto the hot thermoplastic line and the excess thermoplastic trimmed away from around the two steel cubes. After the trimmin, s complete, the steel cubes are removed. A heated steel cube is bonded with epoxy to the square of thermoplastic and allowed to cure overnight before determining the bond strength on a Dillon dynamometer or similar device.
5. Significance and Use
5.1 The function of this test method is to provide numer ical instrumental results indicating the cohesive or adhesive or both, bond strength of thermoplastic traffic marking lo i specified cement brick substrate:
5.2 The use of this test method allows the user and manufacturer to control the quality ofthe product and make-, inferences about the performance of the thermoplastic traffic marking product. Results from these tests also provideinformation helpful in researching and developing thermo plastic traffic marking materials.
5.3 Strict adherence to the procedures outlined is neces sary for precision of the test method. Under no conditions should the bond strength be accepted unless there is ecuformance to 9.14. Precise results are obtained only when one steel block is epoxied to the thermoplastic traffic marking on the cement brick.
6. Types of Separation in Bond Strength Tests
6.1 Thermoplastic lo Steel Cube Separation--This type of separation occurs where there is an insufficient bond be tween the thermoplastic and steel cube probably due to1 insufficient coverage of the epoxy adhesive.
6.2 Thermoplastic to Thermoplastic Separation--This type ofseparation is caused by internal cohesive failure of the thermoplastic. This separation is acceptable when it exceeds) the specified bond strength.
6.3 Thermoplastic to Cement Brick Separation--This type of separation is caused by the failure of the bond between the thermoplastic specimen and the cement brick.
6.4 Cement Brick to Cement Brick--This type of sepaution is caused by the internal cohesive failure of the brie. This is due, in most cases, to a bond between the therm plastic and cement brick that exceeds the cohesive strength:
of the cement brick. This separation is not acceptable > en

193C under continuous agitation and reheat under agitation to 218C.
N' 3--Dry powder mixed thermoplastic must be conditioned to
ensure a homogeneous melt necessary for consistent results. Premelted block thermoplastic does not require this conditioning. The specimen may be melted on a hot plate set at 537"C or in a jacketed electric pot. Continuous agitation is necessary to prevent scorching and settling. If the specimen is melted in an oven set at 260*C, the specimen must be agitated every 15 min until 218C is reached.
9.2 Heat the draw down blade to 218C. 9.3 Obtain a dry room temperature cement brick that has been brushed or textured on the side to be coated with thermoplastic. 9.4 Heat one 2 by 2 by 2 in. (5 by 5 by 5 cm) steel cube in an oven or on a hot plate to 49I>C for 2 h prior to making the thermoplastic draw down on the cement brick. 9.5 When the thermoplastic specimen is melted to 218C under continuous agitation, remove the agitator blade from the thermoplastic, 9.6 Remove the draw down blade from the hot plate and immediately place it on the cement brick and make the draw down the full length of the brick with the melted thermo plastic on the brushed or rough textured side of the brick. 9.7 Immediately place two room temperature steel cubes on the thermoplastic approximately 1 in. from each end of the brick and trim the plastic from around the two steel cubes before the plastic cools and hardens. 9.8 Remove the steel cubes by hand and allow the thermoplastic to cool for 1 h. 9.9 Prepare the epoxy solution using the proper resin and hardener ratio and mix thoroughly.
9.10 Remove the steel cube heated to 49C from the oven and place a small amount ofepoxy on the heated cube. P[ace' the steel cube on the thermoplastic square and rub to ensure 1 an even coating and good adhesion. To ensure an event coating, remove the steel cube from the thermoplastic square I and visually inspect the square and cube and then replace the J steel cube on the square and rub. Do not allow any excess! expoxy solution to flow from the steel cube and thermoplastic square onto the cement brick.
N' 4--Only one steel cube can be epoxied at a lime to the
thermoplastic on the brick because the shock of the first pull will cause a premature release of the second thermoplastic square.
9.11 Place a weight such as a cement brick on the steel cube epoxied to the thermoplastic square and allow to cure for a minimum time of 8 h.
9.12 Screw the Vs-in. (15.9-ram) capped bolt into the steel cube epoxied to the thermoplastic and place the brick into : the steel frame mounted onto the dynamometer.
9.13 Set the dynamometer to zero and pull the steel cube at >A in./min.
9.14 Two tests are run on each brick. Separations ,r,volving at least 80 % of the thermoplastic area to the cement4 brick, thermoplastic to thermoplastic, and cement brick to ' cement brick are acceptable for reporting bond strengths.
10. Calculations
10.1 Calculate the bond strength as follows: 10.1.1 Average the readings obtained in 9.13 if the condi-, tions in 9.14 are met. 10.1.2 Divide the average reading obtained by 4. The' result is the bond strength in pounds per square inch. 10.1.3 Ifone ofthe two tests fails then that test is repeated until the conditions of 9.14 are met.
11. Report
11.1 Report the following information: 11.1.1 The type of separation and bond strength, the e batch number, color, and type of thermoplastic. 11.1.2 The determination of the area of separation is subjective. The area not involved in the separation is usualh attached to the steel cube or cement brick.
12. Precision and Bias
12.1 Precision--No general statement of precision can be j made because of lack of sufficient data at this time.
12.2 Bias--No statement of bias can be prepared for 1 test method since there is no absolute method for use as 3 comparative basis.
12.3 Experience dictates that test results with 50 psi are s acceptable.

4. Summary of Test Method
4.1 The thermoplastic material is prepared for the de scribed test methods by melting a sample to its application temperature under continuous agitation. The specimen is then poured into round patties on a clean tin plate or baking pan. The patties are then broken into pieces for ignition in a muffle furnace. The percent binder is calculated from the ashed specimen and the various tests for glass spheres, titanium dioxide, and lead chromate pigment are performed on the ashed residue. The tests for pigment type or glass spheres may be run on the same ashed specimen. Specimen selection and preparation are the same for each sample .5 tested.

10. Percent Binder
7 10.1 Procedure: 10.1.1 Weigh the crucible and ash (see Section 9) to the
nearest 0.1 mg and calculate the percent of organic binder D as follows:
D = [1 - (S/H0] x 100
where: S -- ashed weight ofthermoplastic specimen, g, and W = weight of thermoplastic specimen, g.
11 Percent Glass Beads
11.1 Interferences--Acid-insoluble fillers will affect the glass-sphere analysis and must be removed by some physical separation method or accounted for quantitatively, or both.
11.2 Procedure: 11.2.1 Weigh the crucible and ash (see Section 9) to 0.1 mg and calculate the percent ash. 11.2.2 After the ashed material has been weighed, transfer the ash to a mortar and pestle and grind with minimal pressure to reduce the ash to a fine grained consistency without crushing the beads. Carefiilly transfer the ashed contents into a 400-mL beaker. 11.2.3 Add to the ash approximately 150 mL of cold I +2 HC1 and stir occasionally until the effervescence has ceased completely. 11.2.4 Place the beaker on a hot plate preheated to approximately 260C and boil for 20 min under continuous agitation to dissolve all acid-soluble filler pigments. 11.2.5 Remove the beaker from the hot plate,'and while hot, immediately dilute the contents with 150 mL of cold water. Allow the beads to settle. Decant the water carefully so as not to lose ahy glass beads. 11.2.6 Continue diluting with 150-mL aliquots of water and decanting until the water is nearly clear. Then transfer the residue into a weighed 3-in. 45-pm (No. 325) sieve and wash with 500 mL of cold water. 11.2.7 Dry the sides and the bottom of the sieve with a paper towel and dry for 1 h in a gravity oven preheated to 100`C. ' 11.2.8 Place the sieve in a desiccator and cool to room temperature. Weigh the sieve and glass beads to 0.1 mg and calculate the percent beads G as follows:
G = (B/W) x 100
where: ' B -- weight of the glass beads, g, and
W = weight of thermoplastic specimen, g.
12. Percent Titanium Dioxide
12.1 Procedure: 12.1.1 Weigh the crucible and ash (see Section 9) to 0.1 mg and calculate the percent of ash which is also equal to the percent filler (pigments and beads). 12.1.2 After weighing the above ashed materials, carefully transfer the ash to an agate or similar impervious-type mortar. Grind the ash to a consistent fine powder except for the glass beads. The pulverized ash must be stirred each time specimens are taken to weigh the prescribed amount for the analysis. 12.1.3 Weigh 1 0.1 g of ash for the titanium analysis.

12.1.4 Proceed with the titanium analysis as described in Test Methods D 1394. The Jones Redactor or aluminum reduction method may be used.
12.1.5 At the end of the digestions described in Test Methods D 1394, filter the undigested materials through a' 3-in. 45-p.m (No. 325) sieve with hot water. This will prevent clogging of the Jones Reductor. This step is not necessary if the aluminum reduction method is used.
12.1.6 Calculate the percent of titanium dioxide (TiO,) from the total ash weighed. The result gives the percent of TiO, in the total thermoplastic specimen.
12.1.7 Calculate the percent ash A as follows:
A = (S/W)x 100
where: S = weight of ash, g, and W = weight of thermoplastic specimen used, g.
12.1.8 Calculate the percent of total Ti02 in the T based on percent ash:
T = 0.08 AMN/CSa
where: A = ash (pigment + filler + beads), %, Sa - weight of ash used, g, M = amount, of 0.1 N potassium permanganate
(KMn04) solution used, mL, (see. the paragraph on titration with KMn04 solution of the Procedure section of the Jones Reductor Method of Test Methods D 1394), N = normality of KMnCX, used, C = correction factor for Ti02 pigment used (usually 1.0).' This, represents the purity of the pigment if specified, and 0.08 = weight of Ti02 per 1 mL of 1 N KMn04, g.
13. Percent Lead Chromate
13.1 Procedure: . . 13.1.1 Weigh the crucible and ash (see Section 9) to 0.1 mg and calculate the percent of ash. 13.1.2 After weighing the above ashed materials, carefully transfer the ash to an agate or similar impervious type mortar and grind the ash to a consistent fine powder except for the glass beads. The pulverized ash must be stirred when specimens are taken to weigh the prescribed amount for the analysis.
13.1.3, Weigh I 0.1 g of the ash for the lead chromate (PbCr04) analysis.
13.1.4 Analyze the dry ash as follows:
13.1.4.1 Transfer the ashed specimen to a 500-mL Erlentneyer flask. Add 6 mL of the (KOH) solution (see 7.5) and 10 mL of distilled water. Heat until dissolved. Do not allow to dry. To the hot solution add 50 g of KC1. Dilute with water to 200 mL and swirl until dissolved. Add 16 mL of HC1 slowly. Add 10 g of KI and titrate with the standard sodium thiosulfate solution (see 7.7) using the starch solution (see 7.8) as the indicator. Titrate to a green endpoint.
N' 3--A 10-mL buret may be used since the titrant required is
small for most thermoplastic analysis.
13.1.5 Calculate the percent ash A as follows:
A -- (S/W) X 100
'
where: S = weight of gas, g, and . W = weight of the thermoplastic specimen used, g.
13.1.6 Calculate the percent oftotal PbCr04 in the sample (binder + filler) L based on percent ash as follows:
L = 0.1077 AMN/CSa
where:
ash (pigment + filler + beads), %, C correction factor for PbCr04 pigment used (for ex
ample, 90 to 100 %, normally 1.0). This represents the purity ofthe pigment if specified; M = amount 'of 0.1 N sodium, thiosulfate solution usee mL, . N = normality of sodium thiosulfate used, and Sa = weight of ash used, g.
14. Precision and Bias
14.1 No general statement of precision can be made because of lack of sufficient data at this time.

`iimmary of Test Method
.1 A weighed quantity of the paint sample is diluted , vent-reducible paints in methyl isobutyl ketone and ter-reducible paints in water) and then aspirated into the j'er of an atomic absorption spectrometer. Lead content the paint is determined from a calibration plot of
rbance versus concentration, prepared from standard "ings containing known amounts of lead.
ignifieance and Use
ll Current U.S. regulations restrict the amount of lead '"t may be present in consumer paint products to less than
6 % based on the total solids. This test method provides a
rapid means for screening paints to, determine compliance with those1 regulations. The test method may be adjusted to meet regulations with a different limit on lead content.

7.2 Operational instructions for atomic absorption spectrophotometers vary with different models. Consult the manufacturer's literature for establishing optimum condi tions for the specific instrument used.
7.3 Turn the instrument on and set the wavelength to the 283.3-nm lead line. Apply the current recommended by the manufacturer to the lead source lamp. Allow the instrument to warm up for about 15 min and set the slit width. Adjust the air and acetylene pressure or flow rates and ignite the burner in accordance with the manufacturer's instructions. A background corrector should be used.
7.4 Aspirate each of the diluted standard paints and record the corresponding absorbance readings. Aspirate MIBK or water, as appropriate, between standards.
N' 1; Caution--it is important that MIBK or water be aspirated
immediately after each diluted standard paint to minimize fouling ofthe aspirator/nebulizer system which could change the aspiration rate and absorbance reading. Continued response for lead while aspirating MIBK or water may indicate contamination of the burner head with pigment and require cleaning of the burner head.
N' 2--To be certain that the diluted paint specimen remains
homogeneous during aspiration, the flask containing the specimen may be stirred continuously with a small magnetic stirring bar.
7.5 Construct a calibration curve on linear graph paper by plotting the absorbance readings versus micrograms of lead present in each diluted standard paint as follows:
A = (B x D x E)
where: A = lead present, jug, B = lead in standard paint based on nonvolatile content (see
6-4), ng/g, D = weight of standard paint, g, and E = nonvolatile portion of standard paint, %.
8. Procedure
8.1 Mix the paint to be tested until homogeneous, prefer ably on a mechanical shaker. Determine the nonvolatile content in accordance with the appropriate test method selected by consulting Guide D 2832.
8.2 Prepare at least two replicate specimens by weighing by difference from a weighing bottle or disposable syringe to 0.1 mg, 0.5 0.02-g quantities of the paint being tested, into 10 raL volumetric flasks. Dilute to the mark with MIBK, if the paint is solvent reducible, or with water, if it is water reducible. Mix thoroughly.
N' 3--Adjustment of specimen size and dilution volume may be
made as required for linear calibration and reasonable response for the instrument used as well as for differing lead content limits.
8.3 Aspirate the diluted paint specimens immediately (Caution--Sec Note 1) after mixing and measure the absorbance (see Note 2). Aspirate MIBK or water, as appropriate between specimen aspirations. Determine the micrograms of lead present from the calibration curve.
N ' 4--For maximum accuracy, calibration and standardizaun
(See Section 7) should be completed just prior to aspirating the dilute
paint specimen.

9. Calculation
9.1 Calculate the mean concentration of lead in the nonvolatile portion of the paint specimen as follows:
L=(Cx 100)/{AVxS)
where: L = lead in nonvolatile portion of the paint specimen!!
ppm (pg/g), C = lead in the aspirated specimen solution (8.3), gg, Jjl 100 -- factor derived from multiplying the numerator by>1
100 (to convert NVused to a whole number) and lb1 (to obtain ppm) and multiplying the denominator by 106 (to convert grams of specimen to micrograms), ' NV = nonvolatile portion of paint specimen, %, and 5 = weight of specimen, g.
10. Report
10.1 Report the lead concentration expressed on thffj nonvolatile content of the paint sample.
11. Precision and Bias5
11.1 Precision--The precision estimates are based onf
interlaboratory study in which five different laborno: i
analyzed in duplicate on 2 days, three samples of sober..-. '
reducible paints and three samples of water-reducible paintff
containing from 464 to 742 ppm lead. The within-laboratory!
coefficient of variation was found to be 3.34 % relative at
df and the between-laboratories coefficient of variation w-.x"
6.72% relative at 18 df. Based on these coefficients, thel
following criteria should be used forjudging the acceptobilr.;^
of results at the 95 % confidence level:
11.1.1 Repeatability--Two results, each the mean of du

both absorption and scattering tinting strength must be specified.
3.1.2 tinting strength, absorption--relative change in the absorption properties of a standard white material when a specified amount of an absorbing pigment, black or chro matic, is added to it.
D< ( < --This is the common definition of tinting strength; however, this definition of the term can be mis leading. For example, the tinting strength of a yellow colorant depends on its scattering as well as its absorption. Its tinting strength as determined from a mixture with white provides no information about its behavior when mixed with low-scattering colorants, such as a black.
3.1.3 tinting strength, scattering--relative change in the scattering properties of a standard black material (with no white pigment present) when a specified amount of a white or chromatic scattering pigment is added to it.
3.1.4 For other definitions, see Definitions E 284. 3.2 Descriptions of Terms Specific to This Standard: 3.2.1 drawdown--a layer ofpaint deposited on a substrate by use of a drawdown bar to evaluate the characteristics of the paint.. 3.2.2 drawdown bar--a bar designed to deposit a specified thickness of wet paint film uniformly on a specified test panel or other substrate.
4. Summary of Test Method
4.1 Chromatic paints are diluted with white paint to obtain mixtures that will produce a drawdown having 35 to 45 % reflectance factor at the wavelength of maximum absorption,
4.2 Drawdowns of these mixture paints are produced at complete hiding.
4.3 The drawdowns are measured, to obtain tristimulus filter readings A, G, B either directly or by computation from CIE tristimulus values X, Y, Z.
4.4 One ofthe samples is designated the standard, and the percents of tinting strength, % TS, of the others are calcu lated relative to that of the standard. Provision is made for correcting this tinting strength for small differences in hue, chroma, or both, between the standard and the test spec imen, and for obtaining an average tinting strength and a range.
5. Significance and Use
5.1 Tinting strength may be one factor in judging the relative economic value of paints, since pigment concentra tion contributes to strength in a major way; other factors are formulation and color development in grinding. The user may also select products for other properties, such as
859
DUP05 02 98039
transparency, that are accompanied by different tinting strengths. The results of this test method may be used for production control or quality comparisons.
5.2 The product with the greatest or the least tinting strength may not be the most desirable for a given artistic use. For example, low tinting strength may lead to the need to use an excessively high pigment concentration to obtain a desired color effect, and this may lead to defects in the dry paint film.
5.3 This test method applies only to single-pigment paints. The tinting strength of paints that contain two or more chromatic pigments with different optical properties cannot be evaluated by this test method.
5.4 The term "similar chemical type" used in 1.1 does not limit the ingredients in the paints to identity, but refers to compatibility in the case of vehicles and to: similarity in the case of pigment types.
5.5 While the instrumental evaluation of tinting strength is described, visual comparisons can also be used, with lower precision, and should be made to provide confirmation of the instrumental and computational results.
5.6 If the sample and standard are widely different in appearance when prepared at the same ratio of chromatic to white paint, another sample should be prepared to bring the two closer in appearance, to obtain the most accurate results.
5.7 The quantities, of chromatic and white paints mixed must be accurately known, on either, a weight , or a volume basis, but the concentration of pigment in the chromatic paint need not be known.
5.8 When the paints being compared have the same vehicle and pigment (same Colour Index name and number) the values of uncorrected tinting strength from 9.1 and corrected tinting strength from 9.2 should be nearly the, same. If they are not, an average of the two tinting strengths is recommended as the best estimate of the true value, and a range provides a measure of the magnitude of the uncer tainty, which is due to differences in hue or chroma, or both, between- the paints.
5.9 Strictly speaking, the Kubelka-Munk-type analysis of this test method should not be applied to the tristimulus filter readings used, but only to spectral data. For the purposes of the relative comparisons of this test method, however, the errors introduced by the calculations used cancel to an adequate degree.

Alternatively, a commercial titanium-dioxide white artists' paint may be used. Th mixing white paint must be made with the same vehicle tyi (acrylic, alkyd, or oil) as the paints to be tested.
7. Specimen Preparation
7.1 Obtain representative samples of the chromatic pr.i, to be tested. For tube paints; expel the entire contents ol il tube and mix thoroughly before sampling.
7.2 Determine the approximate amount of chromat paint to be added to 20 g of mixing white paint to obtain drawdown with 35 to 45 % reflectance factor at the wav length of maximum absorption. If the amount of chromat paint is not known in advance, consult the tables Appendix X1. For pigments other than those listed, use the general guideline the addition of 5 g of chromatic pa, containing an inorganic pigment or 1 g of chromatic pai. containing an organic pigment to the 20 g of miking whi paint.
N' 1--Appendix Xi of Test Method D 4303 describes a methi
for computing the necessary adjustments in quantities required additional trials arc needed to obtain the desired level of reftectaa factor.
7.3 Weigh out the chromatic and mixing white paints the nearest 0.01 g, and mix thoroughly.
7.4 Prepare drawdowns by placing the paint mixtui: one end of an opacity chart and pulling the drawdown b. smoothly through the paint and across the chart. Paste pain should ,be spread with a spatula or palette knife over t! entire chart area to be covered before pulling the bar dots the chart.
7.5 Allow the drawdowns to reach the dry-to-touch tirr as described in the Procedure section of Test Metbe D 1640. Acrylic paints should dry in air overnight. Ajkj paints may require 5 days to dry. Oil paints may require months to dry.
7.6 Determine whether each drawdown is at completi1 hiding by measuring the portions of it over the black and over the white areas of the chart to determine tristimul value Y or colorimeter reading G. If the quotient YJYv, Ge/Gw, where the subscripts refer to measurements c black and white, respectively, is greater than 0.98, fire drawdown can be considered at complete hiding. If the' drawdown is not at complete hiding, prepare a thickr$! drawdown or a drawdown made with multiple coats ofpainty one over another.
N' 2--At the required dilution with while, a drawdown bar with
an aperture of 0.006 in. (0.15 mm) will usually make a drawdown at' complete hiding. In the eases of some acrylic paints and a few oil pamls it may be necessary to increase the aperture to 0.010 in. (0.25 mm) to obtain complete hiding. If this leads to a slow-drying film or a film I > is wrinkled when dry, multiple coats can be applied by depositing ?second 0.006 in. (0.15 mm) coat, drawing down at a right angle to the first coat. After this coat dries, a third coat can be applied if necessart by using a shorter bar that rides over the previous coats.

. Procedure
8.1 Obtain values ofR, G, B for each sample by either of ne two following procedures.
8.1.1 Measure the drawdown with a spectrophotometer or tristimulus colorimeter to determine 1931 CIE tristimulus alues X, Y, Z for CIE standard illuminant C. Follow 'ractice E 1164 and Method E 308. If hemispherical (interating-sphere) geometry is used, measure with the specular omponent excluded. 8.1.2 If a colorimeter that is direct reading in >R, G, B is ised, measure these quantities. 8.2 If X, Y, Z are measured, calculate R, G, B by use of he following equations:
R - 070.98 - 0.2Z/I.l8)/0.8
(1)
G= Y
(2)
B = Z/1.18
(3)
N' 3--The use of the 1931 CIE system (and standard observer) nd standard illuminant C is specified because all known tristimulus olorimeters that are direct reading in R, G, B measure for these
onditions. If values of X, Y, Z are obtained by spectrophotometry, the 964 CIE system and other CIE standard illuminants may be used. Equations 1 to 3 are specific to the conditions, and must be replaced by be appropriate equations if other conditions are specified.7 The article Jsferenced also discusses correcting the measured values for surface Elections.

4. Summary of Jest Method
4.1 Fundamentals--Carbon can occur in water as an inorganic and organic compound. This test method can be used to make independent, measurements of IC, TOQ and
TC, and can also determine IC by the difference of TC and TOC, and TOC as the difference of TC and IC. ,
4.2 The essentials of this test method are: (a) removal of IC,. if desired, by acidification of the sample and sparging by carbon-free gas; (b) conversion pf remaining carbon to CQ2 by action of persulfate, aided either by elevated temperature or ultraviolet (U.V) radiation; (c) detection; of C02 that is swept out .of the. reactor by a gas stream; and (d), conversion of detector signal to a display of carbon concentration in mg/L, A diagram, of suitable apparatus is given in Fig. 1.
5. Significance and Use
. jt
5.1 This test method is used for determination of the
carbon content of water from a variety ofnatural, domestic,
and industrial sources. In its most common form, this test
method is used to measure organic carbon as a means of
monitoring .prganic pollutants in industrial wastewater.
These measurements are also used in monitoring waste
treatment processes.
1
5.2 The relationship of TOC to other water quality
parameter^.such as chemical oxygen demand (COD) and
total'Oxygen demand (TOD) is described in the literature.3
6. Interferences and Limitations
6.1 The oxidation of dissolved carbon to C02 is brought about at relatively, low temperatures by the chemical action of reactive species produced by hot or UV-irradiated persulfate ions. Even-if oxygen is used as the sparging gas, it makes a much lower contribution to, oxidation than in high-temperature (combustive) systems. Not all suspended or refractory material may be oxidized under these condi tions; analysts, should take steps to determine what recovery is being obtained. This may be done by several methods: (a) by monitoring reaction progress to verify that oxidation hasbeen completed; (b) by rerunning the sample under more vigorous reaction conditions; (c) by analyzing the sample by

an alternative method known to result in full recovery; or (d) by spiking samples with known refractories and determining recovery.
6.2 Chloride ion tends to interfere with oxidative reaction mechanisms in this test method, prolonging oxidation times and sometimes preventing full recovery. Follow manufactur er's instructions for dealing with this problem: See Appendix
X1 for supporting data. 6.3 Homogenizing or sparging of a sample, or both, may
cause loss of purgeable organic compounds, thus yielding a value lower than the true TOC level. (For this reason, such measurements are sometimes known as nonpurgeable or ganic carbon (NPOC)). The extent and significance of such losses must be evaluated on an individual basis. This may be done by comparing the TOC by difference (TC-IC) with the direct TOC figure, that is, that obtained from a sparged sample. The difference, if any, between these TOC figures represents purgeable organic carbon (POC) lost during
sparging. Alternatively, direct measurement of POC can be made during sparging, using optional capabilities of the analyzer.
6.4 Note that error will be introduced when the method of difference is used to derive a relatively small level from two large levels. For example, a ground water high in IC and low in TOC will give a poorer TOC -value as (TC-IC) than by direct measurement.
7. Apparatus
7.1 Homogenizing Apparatus--A household blender is
generally satisfactory for homogenizing'immiscible phasesin
water.
.'
7.2 Sampling Devices--Microlitre-to-millilitre syringes
are typically required for this test method. Alternatives
include manually operated or automatically operated sam
pling valves. Sampling devices with inside diameters as small
as 0.15 mm may be used with samples containing little or no
particulate matter. Larger inside dimensions such as 0.4 mm
will be required for samples with particulate matter.
N' 1--See 6.1 concerning oxidation of particulate matter.
7.3 Apparatus for Carbon Determination--This instru ment consists of reagent and sample introduction mecha nism, a gas-sparged reaction vessel, a gas demister or dryer, or both, an optional C02 trap, a C02-specific infrared detector, a control system, and a display. Fig. 1 shows a diagram of such an arrangement.
7.3.1 Sparging requires an inert vessel with a capacity of at least double the sample size with provision for sparging with 50 to 100 mL/min of carbon free gas. This procedure will remove essentially all IC in 2 to 10 min, depending on design.
7.3.2 Oxidation--The reaction assembly contains reagent and sample introduction devices, and a reactor vessel with sparging flow ofcarbon-free gas. The vessel may be heated by an external source, and may contain a UV lamp. The reaction vessel and sparging vessel (see 6.3.1) may be combined.
7.3.3 Gas Conditioning--The gas passing from the reactor
is dried, and the C02 produced is either trapped and later released to the detector, or routed directly to the detector through a chlorine-removing scrubber.
7.3.4 Detector--The C02 in the gas stream is detected by a COrspecific nondispersive infrared (NDSR) detector.
7.3.5 Presentation ofResults--The NDIR detector output is related to stored calibration data and then displayed as milligrams of carbon per litre. s
8. Reagents and Materials
8.1 Purity ofReagents--Reagent grade chemicals shall h;
used in all tests. Unless otherwise indicated, it is intended
that all reagents conform to the. specifications of the Com
mittee on Analytical Reagents of the American Chemical
Society,4 where such specifications are available. Other
grades may be used, provided it is first ascertained that the
reagent is of sufficient purity to permit its use without
lessening the accuracy of the determination.
,
8.2 Purity of Water--Unless otherwise indicated, refer
ences to water shall be understood to mean reagent water,
conforming to Specification D 1193, Type I or Type 11 'I he
indicated specification does not actually specify inorganic
carbon or organic carbon levels. These levels can affect the
results of this test method, especially at progressively lower
levels of the carbon content in the samples to be measured?
Where inorganic carbon in reagent water is significant;
C02-free water may be prepared from reagent water by
acidifying to pH 2, then sparging with fritted-glass sparger
using COz-free gas (time will depend on volume and gas flow
rate, and should be determined by test). Alternatively, if the
carbon contribution of the reagent water is known accu
rately, its effect may be allowed for in preparation of
standards and other solutions. C02-free water should be
protected from atmospheric contamination. Glass containers
are required for storage of water and standard solutions. ,
8.3 Acid--Various concentrated acids may be used for
acidification of samples and of the oxidizing reagent. Acids
such as phosphoric (sp gr 1.69), nitric (sp gr 1.42), or sulfuric
(sp gr 1.84) are suitable for most applications. Sulfuric acid

I be used in the form of a 1 + 1 dilution, for safety asons. Hydrochloric acid is not recommended.
f 8.4 Organic Carbon, Standard Solution (2000 mg/L)--
Choose a water-soluble, stable reagent grade compound, |uch as benzoic acid or anhydrous potassium hydrogen ghthalate (KHC8H404). Calculate the weight of compound inquired to make 1 L of organic carbon standard solution; fbr example, KHCgH404 = 0.471 g of carbon per gram, so t|ne litre of 2 g/L ofstandard requires 2/0.471, or 4.25, grams iff KHP. Dissolve the required amount of standard in some p02-free water in a 1-L volumetric flask, add I mL of acid, fed dilute to volume. This stock solution, or dilutions of it, fay be used to calibrate and test performance of the carbon (ftalyzer.
8.5 Persulfate Solution--Prepare by dissolving the appro bate weight of potassium or sodium persulfate in 1 L of ater, to produce the concentration specified by the instru ment manufacturer. If specified, add 1 mL of phosphoric Kid (sp gr 1.69) and mix well, Store in a cool, dark place, teeipes for this reagent solution may be modified by manufacturers to meet the needs of specific applications, for ;kample, high chloride samples.
8.6 Gas Supply--A gas free of C02 and of organic matter -required. Use a purity as specified by the equipment
anufacturer. The use of oxygen is preferred for the UVIrsulfate method, and nitrogen or helium is preferred if a X>2 trap is used between reactor and detector.
9. (Sampling and Sample Preservation
p.9.1 Collect the sample in accordance with Specification >1192 and Practice D 3370.
^9:2 To preserve Samples for this analysis, store samples in jjla^s at 4C. To aid preservation, acidify the samples to a pH (flUIt should be noted that acidification will enhance loss of jffjrganic carbon. If the purgeable organic fraction is imporJjBtt, fill the sample bottles-td overflowing vnth a minimum pf turbulence and cap them using a fluoropoiymer-lined cap, Jdtjhout headspace. Jr:3 For monitoring of waters containing solids or immisble liquids that are to be injected into the reaction zone, use Prhechanical homogenizer or ultrasonic disintegrator. Filjjgtihg or screening may be necessary after homogenization to ijeet particle sizes that are too large for injection. Volatile panics may be lost. See 6.3. 1914 For wastewater streariis where carbon concentrations
(greater than the desired range of instrument operation, tlute the samples as necessary.
|l Instrument Operation
10.1 Follow the manufacturer's instructions for instruaent warmup, gas flows, and liquid flows.
Calibration
11.1 Use the stock solution of 2000 mg/L of carbon, and arious dilutions of it, for calibration.
No t ' 2--Dilutions should be made with COj-free water (see 8.2).
11.2 Calibration protocols may vary with equipment nufacturers. However, in general, calibrate the instrument . accordance with the manufacturer's instructions, and use ndards to verify such calibration in the specific range of
interest for actual measurements. Plots of standard concen tration versus instrument reading may be used for calibra tion or to verify linearity of response.
11.3 Establish instrument blank according to the manu facturer's instructions.
12. Procedure
12.1 Mix or blend each sample thoroughly and carry out any necessary dilution to bring the carbon content within range of the instrument.
12.2 If inorganic carbon is to be measured directly, inject the sample into the analyzer under appropriate conditions.
12.3 If inorganic carbon is to be removed by sparging prior to sample introduction, acidify to approximately pH 2 with concentrated acid (if not already done) and sparge with an appropriate flow ofgas. Samples with high alkali content or buffer capacity may require larger amounts of"acid. In such cases, incorporate this dilution into the calculation. If incomplete sparging of C02 from IC is suspected, sparge and analyze the sample and then repeat the procedure until appropriate conditions are established. In difficult condi tions, use of a fritted-glass sparger may help.
12.4 To measure TOC, inject an appropriate volume of the sample into the analyzer. If external sparging is required to remove IC, inject a sparged sample for the TOC measure ment See 6.3.
12.5 To measure TC, inject an appropriate volume of unsparged sample.
13. Calculation
13.1 Read carbon values directly from a digital display or
printer, or both.
'
14. Precision and Bias5
14.1 Collaborative Test--This test method was evaluated by sending seven identical sample to each of ten laboratories and asking them to measure TOC and TC exactly in accordance with this test method. Three of the ten laborato ries did not make the TC measurement. One of the samples consisted of laboratory reagent water: The other six were of that water spiked to various levels with' acetic acid, pyridine, arid sodium carbonate. TC leivels ranged from 0.6 to 2 000 mg/L, and TOC levels from 0.3 to 1 700 mg/L. An Ftest at 95% confidence level showed no significant difference between the results of the five laboratories using UVpersulfate oxidation and those of the five laboratories using hot persulfate. Consequently, results were pooled for further analysis.
14.2 Removal of Outliers--Application of outlier tests specified in Practice-D 2777 - 85 resulted in the elimination of one laboratory's TC and TOC results. In addition, three laboratories did not perform the TC analysis, so the effective number of laboratories was six for the TC measurement. Five of their individual results were later eliminated by outlier test. In the TOC determination, one additional laboratory failed the outlier test, leaving a total of eight. Three individual results were later eliminated.

,14.3 Precision--Separate determinations of precision were made for TC and TOC measurements:
For TC: S, -- 0.03x + 0.3 S, = 0.0U + 0.2
For TOC:St = O.OSx + 0. ; S0 = 0.04x + 0.1
where: x = the recovered C concentration, mg/L, S, = overall precision, and Sa - single-operator precision. Fig. 2 shows a log-log plot of the overall and single-operator precision of all TC and TOC measurements not eliminated by outlier tests.
14.4 Bias--Fig. 3 plots "amount added" against "amount foUnd," with overall precision shown as an error bar. Bias significant at the 95 % level (student's t-test) is flagged. Water that was used as one ofthe samples is omitted, since no value equivalent to "amount added" is available. The contribution ofthe carbon in the water to the spiked samples was allowed for before analysis of bias. In general, bias is positive, with the values running from 1 % to 25 % of the amount added, with no particular pattern evident. Of the twelve bias measurements, ten were below 10 %. Users of this test method should make their own determination of bias,
14.5 Matrix Effects--Participants were asked to measure the TC and TOC levels in a water sample of their choice, and
FIG. 3 Bias: Amount Added Versus Amount Recovered
then to spike the sample with one of the study samples and to measure the sample again. The chosen samples were: sinf waste; DI water with KHP; soil solution; tap water witl. added IC; plant waste stream; synthetic sewage, and anion resin brine wash. TC recoveries averaged 86 % (range from 74 % to 92 %), and TOC, 82 % (from 47 % to 92 %). The negative bias, versus the positive bias noted in 14.4, can reflect incomplete oxidation of spiking compounds in the presence of other organics, errors introduced by sample handling, or other effects. In any event, no one matrix was studied in sufficient depth to provide an answer. Users ofthis test method should conduct their own experiments to determine recovery in their particular circumstances.
14.6 The quality assurance (QA)/quality control (QC) portion of this test method has not been completely estab-j lished at this time. It is the intent of Subcommittee D 19.06 ; that procedures be incorporated into this test method that: require a minimum level of QC. These procedures will I require, at minimum, a method startup check and ongoing ! performance' checks. The analysts performing this test! method will be required to measure their performance against the performance level achieved by the laboratories that participated in the ASTM round-robin study done on this test method. These formal QC procedures will bi i incorporated at such time as they have been officially accepted by the Society. See Practice D 4210.

4. Significance and Use
4.1 This test method is intended to measure the erosion rates ofablative antifouling paint systems exposed to flowing water at velocities designed to subject the paint system to shear stresses experienced in service.
4.2 Measurement of erosion rates are necessary to help in the assessment of ablative antifouling paint film thickness required for fouling control between scheduled drydockinas , of ships, in the selection of materials, in producing quality * assurance, and in understanding the performance mecha-M nism.
4.3 The test data is intended to serve as a guide gggjj predicting the service life of ablative antifouling paintsItf'1' order to calculate the necessary paint thickness to fit' specified deployment cycles. Erosion rates of antifouling paints in service will vary depending on such factors ggjf berthing location, geographic area of operation, salinity, pH,' and temperature of seawater. It should also be recognize;a| that some areas of the ship are subject to different erosibflj rates.
4.4 The degree of correlation between results obtained! from this test method and shipboard service has not beeii|j determined.
5. Apparatus

8.4 Apply additional coats of antifouling paint in accord ance with Military Specification DOD-P-24647 or the man ufacturer's instructions, whichever applies. The last coat shall dry for a minimum of 7 days before any erosion testing.
8.5 Both sides of the painted test surfaces are provided with noneroding reference (NER) points before immersion in the test environment. The NER is an insoluble, tightly adherent vinyl or other suitable, compatible coating 2 0.5 cm/diameter applied in the center of the panel which will blanket a portion of the eroding surface. The NER preserves the original outer surface of the antifouling and thus offers a reference for comparison with the eroded surface during later microscopic examination.
8.6 Take film thickness measurements before and after testing (see 5.2).
8.7 Panels are to be photographed prior to starting the test for comparison with photographs taken at the conclusion of the test.
8.8 A specimen of exposed antifouling paint is carefully removed for examination in a single flake which includes a fragment of the noneroding reference. This specimen is mounted for microscopic analysis in a suitable medium such as paraffin wax or epoxy resin. Care is required to ensure that the specimen is not damaged by solvent attack or heat evolution during this encapsulation.

Designation: D 4940 - 89
Standard Test Method for
Conductitnetric Analysis of Water Soluble Ionic Contamination of Blasting Abrasives1
This standard is issued under the fixed designation D4940; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year oflast revision. A number in parentheses indicates the year of last reapprovat. A superscript epsilon () indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method describes a procedure for rapid evaluation of abrasives for the presence ofionic contamina tion by determining the total concentration of water soluble ionic contaminants by means of a conductivity test.
1.2 This test method does not identify the ionic species present nor provide quantitative results on each species.
1.3 This test method is based on a volume comparison among abrasives of similar sizes. A volume comparison is more closely related to surface area of the abrasives than is a weight comparison.
1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.
1. Referenced Documents
2.1 ASTM Standards: D 1193 Specification for Reagent Water12 E 832 Specification for Laboratory Filter Papers3
3. Summary of Test Method
3.1 Abrasive and pure water are combined into a slurry that is stirred to leach the soluble salts from the abrasive. This slurry is filtered and conductance of the filtrate is measured. The conductivity, which is related to the concen tration of soluble ionic materials contaminating the abrasive surface, is calculated from the conductance and die cell constant.
4. Significance and Use
4.1 By-product abrasives manufactured from slags that are air cooled or quenched with pure water, normally contain low concentrations of ionic materials as do mined mineral abrasives. However, slags quenched with seawater or other contaminated water, contain high amounts of ionic material as does seashore sand. This contamination of the abrasive can transfer to the steel surfaces being blasted, where it may accelerate corrosion. This test is useful in establishing the cleanliness of the abrasive at the jobsite.
4.2 This test method provides a value that indicates the concentration of total water soluble ions in accordance wit i their electrolytic mobility. Thus, it provides an indication nl ionic corrosion potential.
N' 1--A typical value of conductivity for a high level of contain.
ination is 500 pmho/cm. A typical value for a low level of cantamination is 50 pmho/cm
5. Apparatus
5.1 Conductivity Bridge and Cell--Any commercial cor.ductivity bridge and conductivity cell having a range of at least 5 umho/cm to 1 000 000 (xmho/cm and temperature compensation capability is satisfactory. Either a dip-typ:, pipet-type, or cup-type cell may be used. A means of adjusting for temperature or controlling the temperature is essential. While some instruments have an adjustment to compensate for temperature, one means is to use a 25 C constant temperature bath. Another method is to stir ihe solution with a clean thermometer while the vessel is wanned or cooled by an external source.
N' 2--If temperature compensation or control is not followed correctly, an error of approximately 2 % per degree of temperature deviation from 25C can be introduced. The deviation of conductivity with temperature in-the raftge of 18"C is reported to be 0.0216 % pet degree for chloride ions and 0.0227 % per degree for sulfate ions.
5.2 Filter Paper, conforming to Specification E 832, Tjpc 1, Class C, to keep silt from fouling the surfaces of ihe conductivity cell.
6. Reagents and Materials
6.1 Purity ofReagents--Reagent grade chemicals shall be used in till tests. Unless otherwise indicated, it is intended that all reagents conform to the specifications of the Com mittee on Analytical Reagents of the American Chemi'.il Society where such specifications are available.4 Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination.
6.2 Purity of Water--Unless otherwise indicated, refer ences to water shall be understood to mean reagent water as defined by Type IV of Specification D 1193.
6.3 Potassium Chloride (KC1 or 0.02 N KC1 solution).

Sampling
7.1 Sampling shall be as follows unless otherwise agreed upon between the purchaser and the seller. Take two 1-L ampies of abrasive at random from different packages of 'Uadi lot, batch, day's pack, or other unit of production in the |ipment. When no markings distinguishing between units if production appear, take samples from the different packages in the ratio of two samples for each 10 000 lb 000 kg), except that for shipments of less than 10 000 lb, |ake two samples. Test the samples separately.
Calibration and Standardization
Hj8.1 Determination ofCell Constant: 1 8.1.1 The conductivity cell will come with a predeter mined constant. This constant should be checked periodi cally, one method being as follows:
8.1.1.1 Prepare a standard solution such as a 0.0005 N fiilution of KCI by diluting a 0.02 N KC1 solution with water Ir by dissolving 0.0372 g of KCI (heated before weighing for 1% at 105C) in water, followed by dilution to 1 L. Cool and Seasure the conductance at 25C as described in Section 9. Calculate the cell constant, as follows:
*25 = (cycj
^here: = conductance, measured at 25"C (see 10.1), pmho, and = conductivity, 72 pmho/cm (from Table 1).
J|N' 3--In general the cell constant is not greatly affected by
pHations in the strength of the KCI solution, but, for greater accuracy,
jeasurements should be made at or near the specific conductivity ofthe Itotion to be measured and at values that utilize the middle range ofthe
pale of the conductivity bridge, using tire same multiplier tap.
8.1.2 Table 1 gives values of specific conductivities for iSrresponding KCI solution concentrations which are useful pr abrasive testing.
.Procedure
. 9.1 Preparation ofa Slurry Filtrate: | 9.1.1 Rinse beakers, stirring rods, and funnels with rekent water until tests show the rinse water has a conduc|yity of 5.0 pmho/cm or less. Hi9.1.2 Add 300 mL of water to 300 mL ofabrasive and stir
: 1 min with a stirring rod. Let stand for 8 min and then again for 1 min. u9.1.3 Filter sufficient supernatant liquid for tests, dis carding the first 10 mL of the filtrate. The amount of jrpernatant liquid filtered shall be sufficient to cover the cell. '9.1.4 Rinse the conductivity cell in reagent water until the pise water is a cleanliness of 5.0 pmho/cm or less. 1;9.1.5 Rinse the conductivity cell two or three times with he filtrate then determine conductance at 25C in accordfhee with the operating instructions of the instrument. Use
successive portions of the sample until a constant value is obtained.
10. Calculation
.10,1 Calculate the specific conductivity of the abrasive as follows:
Cs -- C'm x
11. Report
11.1 Report the following information: 11.1.1 The calibration value of the cell constant (both as measured and as predetermined and supplied with the conductivity cell), the date, and the name of the person checking the calibration. 11.1.2 The material, date, readings and mean in jtmho/ cm along with name of person conducting the tests and identification of the apparatus.
12. Precision and Bias3
12.1 Precision--On the basis of five replicate interlaboratory tests of this test method in which three operators in three laboratories analyzed, in duplicate, six blasting abra sives containing ionogenic contamination, the within-laboratory coefficient ofvariation after rejecting results from one set of replicate tests as outliers, was found to be 1.7% with 20 degrees of freedom (df) and the between-laboratory standard deviation coefficient of variation was found to be 7.4 % with 15 df. Based on these coefficients, the following criteria should be used forjudging the acceptability of results at the 95 % confidence level:
12.1.1 Repeatability--Two results, each the mean of two runs obtained by the same operator should be considered suspect if they differ by more than 5 % relative.
12.1.2 Reproducibility--Two results, each the mean of two runs, obtained by operators in different laboratories should be considered suspect if they differ by more than 22 % relative.
12.2 Bias: 12.2.1 Bias can be present because of the mobility of various ions. The hydrogen ion has a much greater mobility than the hydroxyl ion or other ions so that at low pH's the conductivity will be relatively higher than at high pH's for the same ionic concentration. However, the bias introduced by this factor is in the proper direction. That is, high conductivity due to a lower pH of the contamination would normally indicate greater corrosion potential. 12.2.2 A bias may be introduced by extraneous contami nation or from reduced sensitivity of instruments for low levels of contamination in the range of conductivity between 0 and 30 jimho/cm.

Terminology
1 3.1 Definitions'--See Definitions D 16 for definitions of terms used in this practice. 1 3.2 Descriptions of Terms Specific to This Standard:
3.2.1 drawdown bar--a metal applicator with a specified sgap designed to deposit a wet paint film uniformly on a specified test panel (for example, an opacity chart) or other ' ubstrate.
3 2 2 drawdown--a layer of paint deposited op a substrate by se of a drawdown bar for the evaluation of paint characteristics.
Summary of Practice
4.1 The paint is spread over the area ofthe test panel to be covered by the drawdown and the bar is pulled down with pressure just sufficient to avoid lifting of the bar from the chart surface.
4.2 Test panels are allowed to dry in a dust-free environ
ment. 4.3 If complete hiding (opacity) is needed and not pro-
duced by a single paint film, a second film is applied at a 90

angle to the first. If required, additional layers may be applied using a narrower drawdown bar.
5. Significance and Use
5.1 Quality standards for artists' paints require the evalu ation of various appearance characteristics of paint films. Tinting strength determination (Test Method D 4838) specif ically requires the preparation of drawdowns for colorimetric measurement. Other evaluations such as color designation, transparency, gloss, and color difference measurements also require drawdown samples.
5.2 Artists' tube paints have a paste consistency that makes the use of traditional film application methods difficult, especially for drying oil paints.
5.3 Artists' paints vary in two properties important to the preparation of films, that is, transparency and drying time. Colorimetric determination and some other types of evalua tion require paint specimens that completely hide the substrate. Very, transparent paints require such a thick film to produce complete hiding that drying times is excessively long or the specimen surface is blemished. When complete hiding is necessary, this practice is designed to provide opaque films without these defects through application of a series of thin film..
6. Apparatus
6.1 Drawdown Bars, two, of different widths with a clear ance of 0.006 in. (0.152 mm). Recommended widths are 3 in. (7.6 cm) and 6 in. (15.2 cm). The second bar is required to prepare drawdowns with more than two layers. Wire wound drawdown bars have been found to be unsuitable.5
6.2 Drawdown Charts, sealed paper type, half black and half white if transparency is being evaluated or opacity is necessary.6
7. Procedure 7.1 Attach chart to a firm, smooth, level plane surface
using tape, a vacuum plate, or a clamp. Label the chart with the identity of the specimen and other data as required.
7.2 Mix paint sample thoroughly using two spatulas. Tube paints that have separated should be expelled completely and mixed.

surface simplifies clean up. The same paper can be used for weighing

specimens when required as in the tinting strength determination (Test
Method D 4838).
7.3 Using a spatula, spread the paint, in a thickness exceeding the bar's gap clearance, over the entire area to be covered by the drawdown. Do not cover the area to be contacted by the supporting feet of the wider of the two bars. Starting at the top of the chart and using the wider bar, draw the bar down over the paint in an even rnotion applying sufficient pressure to ensure that the resistance of the viscous paint does not raise the feet of the bar from the surface. When using oil paints the motion should be slow enough to allow for the high viscosity. Acrylic paints, which have short drying times, should be applied immediately after mixing to avoid premature film formation.
7.4 After drying in a horizontal position for 15 min, specimens may be hung in a vertical position in a dust-free area to complete the drying. Allow 24 h for acrylic and alkyd paints and 48 h or longer for oil paints until dry to touch.
7.5 Examine the specimen for surface defects and discard if unacceptable.
7.6 If complete hiding is required, compare, either visu ally or instrumentally, the lightness of the paint on the black portion ofthe chart with that on the white. For instrumental evaluation, follow the procedures given in Practice E 1164 to determine CIE Y for each portion, then calculate the contrast ratio of the paint film on the two portions of the chart (CIE f|-.iack/CIE Fwhite). A .contrast ratio of 0.98 or higher is considered opaque.

Designation: D 4942 - 89
Standard Test Methods for Water Pickup of Lithographic Printing Inks and Vehicles in a Laboratory Mixer1
This standard is issued under the fixed designation D 4942; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapprovol. A superscript epsilon le) indicates an editorial change since the last revision or reapproval.
Scope
ill These test methods cover two procedures for deterning the amount of water picked up by lithographic nting inks in a laboratory mixer. 1.2 Test Method A covers single-point water pickup; Test thod B covers the rate of water pickup. Both test methods applicable to any printing ink and vehicle intended for [lithographic printing process. .3 This standard may involve hazardous materials, oper;ns, and equipment. This standard does not purport to `dress all ofthe safety problems associated with its use. It is
responsibility of the user of this standard to establish ropriate safety and health practices and determine the $j?licability ofregulatory limitations prior to use.
^Summary of Test Method
'2.1 These test methods utilize a laboratory mixer for .ting water or other agreed upon fluid into the lest ink.
2 For single-point water pickup (Test Method A), 50 of water is normally added to 50 g of ink and mixed in ;r 5 min. The water picked up is determined from voluetric measurements of free water. 2.3 For rate of water pickup (Test Method B), water is dded to 50 g of ink in increments of 20 mL and mixed in 11 min or more over a cumulative time period totaUng 10 in. The water taken up by the ink after each mixing ierval is determined gravimetrically.
Significance and Use
3.1 The lithographic printing process requires that some ampening solution be emulsified into the ink. These test -thods provide a rapid means for determining water ickup under laboratory conditions. Test results may be eful for specification acceptance between the supplier and ije customer. 3.2 In order that results be comparable, the tests must be :.n at the same temperature and with the same type and .iantity of liquid added prior to mixing. 3.3 The emulsions obtained in these test methods are of
ger particle size than those typically produced in printing ps. Because of these and other variables in the printing rocess, water pickup results do not by themselves predict ithographic printing performance.

4. Apparatus
4.1 Laboratory Mixer,2 such as a Duke Ink-Water Emul sification Tester2 equipped with a stainless steel specimen bowl 83 mm wide and 88 mm high, mixer blades that rotate at 90 r/min, and a timing device.
4.2 Balance, accurate to 0.1 g, 600-g capacity, 4.3 Palette knives, two. 4.4 Thermometer, quick response. 4.5 pH Meter (optional). 4.6 Conductivity Meter (optional). 4.7 Graduated Cylinder, 50 Or 100-mL.
5. Reagents and Materials
5.1 Water--Deionized or distilled water, preferably having a pH of 5.0 to 7.0 (100 to 200 mL per sample); alternatively, fountain solution or other aqueous medium as agreed upon between the supplier and the customer may be used.
5.2 Cleanup Materials--Naptha and rags or tissues.
6. Test Specimen
6.1 A minimum of 100 g is sufficient for two determina tions. Before removing ink from the can, stir or otherwise ensure that the ink specimen is representative. Close the can and replace sealing tape immediately after each ink removal.
7. Conditioning
7.1 Condition the instrument, water, and ink samples in a constant temperature room or bath, preferably at 23 1C.
7.2 Prior to use, check the alignment of the mixer blades. With the power switch ofthe mixer in the off position, set the clean bowl into the turntable and engage the locking pin firmly into the slot in the side of the turntable. Tilt the mixer head back and insert the blades, marked left and right, into their respective holders.' Lower the mixer head. If the blades hit the side or bottom of the bowl, return the instrument to the manufacturer for realignment.
8. Test Method A--Single Point Water Pickup (by Vol umetry)
8.1 Program the counter of the mixer for 5 min mixing time (450 revolutions).
8.2 Optional--If the first run of the day, pour test water into a beaker. Measure pH, conductivity, and temperature at the beginning of testing.
8.3 Weigh or tare the clean dry mixing bowl. Add 50

0.1 g of the ink to the center of the bowl. 8.4 Pour 50 mL of water (from 8.2) into a graduated
cylinder. If the ink is expected to pick up more than 100 % water, use 100 mL of water. Adjust the volume to 0.5 mL. Add the entire contents to the bowl.
8.5 With the mixer head tilted back insert the clean blades, marked left and right, into their respective holders. Lock the bowl on the turntable. Lower the mixer head. Press the counter reset button, making sure that 450 is displayed on the face of the counter.
8.6 Turn the mixer on. Examine contents of the bowl as mixing progresses. If 50 mL of water had been added and all of it disappears into the ink, stop, discard the ink in the bowl, clean up, and start over from 8.3, adding 100 mL ofwater in 8.4. The latter quantity must also be used for all other inks in the series under study.
No t ' 1--With some inks, water pickup is affected by the amount of water added prior to mixing. When 50 mL is insufficient, do not simply add another 50 mL during the run, as test results may differ significantly from those obtained by adding LOO mL at the outset
8.7 When the mixer stops, turn the power switch off. Tilt the head out of the ink, detach the mixing blades, and add to the bowl.
8.8 Remove the bowl from the turntable and, holding the blades at the side of the bowl, decant the free water into a graduated cylinder. Run the blades very slowly through the ink in the bowl. Decant additional free water into.the cylinder.
N' 2--Do not knock the bowl to force free water from the surface.
Always handle the bowl gently to avoid breaking the emulsion.
8.9 Record the returned water level to 0.5 mL. 8.10 Optional--Measure the temperature, pH, and con ductivity of the returned water. Note the appearance of the water and the consistency of the ink arid the appearance of the returned water. 8.11 Discard ink left in the bowl. Clean the bowl arid the mixer blades with tissue wetted with naphtha. Discard the returned water and rinse the cylinder clean. 8.12 Repeat 8.3 through 8.10 with a second specimen of the same ink.
9. Test Method B--Rate of Water Pickup (by Gravimetry)
9.1 Program the counter for the first interval of the mixing cycle.
N' 3--A commonly used cycle is 1-min intervals (90 revolutions)
times ten determinations. Intervals need not be uniform, for example, 1, 2, 3, 5, and 10 min (90 times 3 plus 180 plus 450 revolutions).
9.2 Optional--Measure water properties in accordance with 8.2.
9.3 Weigh or tare the clean dry mixing bowl and blades on the balance. Add 50 0.1 g of ink to the center of the bowl.
9.4 Lock the bowl on the platform of the mixer. With the mixer head raised, carefully insert the blades into their respective holders. If ink on one blade touches the upper parts of the other blade or the side of the bowl, carefully remove the ink with two palette knives and transfer to the bottom of the bowl. Lower the mixer head.
9.5 Pour 100 mL of water (from 8.2) into a beaker. Meter out 20 mL and add to the bowl.
9.6 Press the counter reset button, making sure that the
desired number of revolutions is displayed on the face of the
counter. Turn the mixer on. Examine the contents of the ! '4$ bowl as mixing progresses. If all liquid disappears into the ''> ink, add more as needed to maintain a layer of excess water on the surface of the ink.
N' 4--Few specimens will take up more than 20 mL of water
within a 1-min mixing interval. If a high-water pickup specimen is being
run and the mixing interval is longer than i min, another 20 mL should be added prior to each subsequent minute of mixing time.
9:7 When the mixer stops, turn the power switch off.
Detach the mixing blades and add to the bowl.
9.8 Remove the bowl from the turntable and, holding the
blades at the side of the bowl, decant the free water into the
beaker containing the unused water. Run the blades very"
slowly through the ink in the: bowl. Decant additional free
water into the beaker (see Note 2).
9.9 Weigh the mixing bowl and contents, including thf
blades.
9.10 Using a palette knife, transfer the ink from the walls
to the center of the bowl. Return the bowl to the mixer
Replace the blades as in 8.4.
i;
9.11 For the next mixing interval, swirl the beaker in,
order to mix the returned and unused water. Meter out 20
mL and add to the bowl. Press the counter reset (or change
the counter) and turn the power on. Add more water i`
needed to maintain an excess layer (see Note 4).
9.12 When the mixer stops, repeat 9.7 through 9.11 until
the cumulative mixing time totals at least 10 min.
9.13 Optional--At the end of the run, make measure
ments in accordance with 8.10.
9.14 Discard the ink left in the bowl. Clean the bowl and
the mixer blades with tissue wetted with naphtha. Discard
returned water and rinse the beaker dean.
9.15 Repeat 9.3 through 9.14 with another specimen cf
the same ink.
10. Calculation
10.1 Calculate water pickup, P, as follows: 10.1.1 Test Method A--Volumetric:
/> = ((/,- F2) x 2
where: P = water pickup, % or mL water/100 g ink, K, = volume of water added, mL, and V2 = volume of returned water, mL.
10.1.2 Test Method B--Gravimetric:
p = (W-S)x. 2
where: P = water pickup, % or g water/100 g ink, W - weight of the specimen plus water picked up after each
.mixing interval, g, and 5 = weight of initial specimen, g.
N' 5--The conversion from water pickup of the ink to water
content, C, of the emulsion is C = P/(l00 + P). Units are percent or grams of water per 100 grams of emulsion.
11. Report
11.1 Report the following information: 11.1.1 The percent water pickup to the nearest whole number as the mean of the two determinations, the cumula tive mixing time, and a description of the water used for

posting (for example, tap water, deionized water, or type of fountain solution).
11.1.2 If rate of water pickup was determined, plot the percent of water pickup versus the cumulative mixing time.
11.1.3 Optional--The mean temperature, changes in pH, onductivity, appearance of the water, and the change in lonsistency of the ink.
|pZ. Precision and Bias
12.1 Precision: H 12.1.1 Test Method A--An interlaboratory study of sin gle-point water pickup by Test Method A was conducted in ^yhich one operator in each of eleven laboratories tested in ^duplicate on each oftwo days three litiiographic printing inks igpging in 5-min water pickup from 50. to 65 %. One Company was found to be an outlier and was deleted from he analysis. The within laboratory pooled standard deviajfibn was found to be 1.58 % absolute (millilitre of water per
00 grams of ink) at 9 degrees of freedom (df), and the jfetween laboratories pooled standard deviation was 7.1 % psolute at 30 df. Based on these standard deviations, the pillowing criteria should be used forjudging the acceptability If results at the 95 % confidence level: r 12,1.1.1 Repeatability--Two results, each the mean of Bvo runs obtained by , one operator, should .be considered fgspect if they differ by more, than 4.5 % absolute.
12.1.1.2 Reproducibility--Two results, each the mean of jjsvo runs obtained by operators in different laboratories, pshould be considered suspect if they differ by more than |0 % absolute.
12.1.2 Test Method B--In an irtterlaboratory study' of rate
of water pickup by Test Method B, water pickup values at 2'h, 5,1'h and 10 min were determined twice on one day by one operator in each of nine laboratories on six inks. The inks ranged in water pickup from 40 to 52 % at 2`A min and from 65 to 100 % at 10 min. After rejecting 12 out of 156 replicated test values as outliers, the within laboratory pooled standard deviation was found to be 1.58 % absolute (grams of water per 100 grams ink) with 97 df and the between laboratory standard deviation 3.73 % absolute with 86 df. Based on these standard deviations, the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
12.1.2.1 Repeatability--Repeatability cannot be deter mined as both runs were conducted on the same day.
12.1.2.2 Reproducibility--Two water pickup curves, each the mean of two ruris, obtained by operators in different laboratories should be considered suspect if they differ by more than 10.5 % absolute.
12.2 Bias--Bias cannot be determined because there are no standard materials. The poorer interlaboratory precision of Test Method A compared to Test Method B is believed to be caused by the faet that the gross quantity of water added at one time is picked up as large globules which make it difficult for different operators to release free water in the same manner:

A number in parentheses indicates the year oflast reappraval. A superscript epsilon (0 indicates an editorial change since the last revision or reapproval.
** N' --Paragraphs 6.5, 7.2, and 7.5 were editorially corrected in October 1990.
1. Scope
1.1 This test method describes an accelerated procedure for evaluating the face-to-face blocking resistance of trades sales paints. This is not to be confused with blocking resistance Test Method D 3003 which is concerned with blocking of industrial coatings on metal substrates, nor with Test Method D 2793 which is concerned specifically with wood product finishes and reports results on a satisfactory or not satisfactory basis, rather than by the degree of blocking tendency as in this test method.
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safetyproblems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

3. Terminology
3.1 Definition: 3.1.1 blocking--The undesirable sticking together of two painted surfaces when pressed together or placed in contact with each other for an extended period of time.
4. Summary of Test Method
4.1 Dried paint films are placed face-to-face and a pres sure of about 1.8 psi (127 g/cm2) is applied. These paint films are put into an oven for 30 min to make the test more stringent. After cooling, the blocked panels are peeled apart. The degree of blocking is rated subjectively for tack or seal using a series of standard descriptive terms corresponding to numerical ASTM values of 10 to 0.
5. Significance and Use
5.1 Dry paint often comes in contact with itself especially in window and door areas and, depending on its hardness,

the pressure, temperature, humidity, and duration of time the surfaces are in contact, sometimes sticks to itself (blocks). This stringent test method can be used to compare and iate subjectively the resistance of paints to blocking.
6. Apparatus
6.1 Conditioned Room, at 65 to 85"F (18 to 29.5C) and 40 to 60 % relative humidity.
6.2 Sealed Paper Test Charts, approximately 7.5 by 11 in, (190 by 280 mm).3
6.3 Applicator Blade, 5 to 6 in. (13 to 15 cm) wide, 6 mil clearance.
6.4 Oven, 1 f 5 to 125F (48 to 52C). 6.5 Rubber Stoppers, No. 8, 1.25 in. (3.2 cm) smallc, diameter. 6.6 Weights, 1000 g. 6.7 Scissors. 6.8 Aluminum Tray or Pan, flat.
7. Procedure
7.1 Cast the paint to be tested on a sealed test chart using the applicator blade. Condition coated panels in the condi tioned room for seven days. All painted panels should be kept free of grease, oil, or fingerprints since these will affect block resistance.
7.2 After the panels have been conditioned, cut out six t`/2 by l'/2-in. (3.8 by 3.8-cm) sections from the paintrv chart. Start the cut at least 'h in. (1.3 cm) away from the edge of the drawdown.
7.3 Place the cut sections with the paint surfaces fac.to-face for each paint to be tested.
7.4 The weights, stoppers, and tray should be temperatureequilibrated in the oven prior to running the test.
7.5 Place the face-to-face specimens in the oven on a flei aluminum tray. Place a No. 8 stopper on top, with the small diameter incontact with the specimens, then place a 1000-g weight on top of the stopper. This results in a pressure of 1 > psi (127 g/cm) on the specimens. One weight and stopper is to be used for each specimen to be tested. It is recommended that "pass" and "fail" paint controls be used in each test run and that the tests be run in triplicate.
7.6 After exactly 30 min, take the stoppers and weights off the test specimens and remove them from the oven. Aliev them to cool for 'h h in the conditioned room before determining the block resistance.

7.7 After cooling, separate the specimens by peeling them apart with a slow and steady force at about 180 from each p other forming a UT" pattern during beginning of the separation. It is necessary to put the specimen next to the ear while separating to actually hear the degree of tack. Rate for flocking resistance on a scale of 0 to 10 (see 8.2).
8. Interpretation of Results
8.1 Blocking resistance is rated on a scale of 10 to 0, . which corresponds to a subjective tack (sound of separation

4. Summary of Test Method 4.1 A 2-in. (50-mm) polyester brush is used to apply the
test paint on a 1.076-ft2 (1000-cm2) test area. The applica tion is made at a spreading rate of 400 ft2/gal (9.82 m2/L) and is completed in 30 to 35 s.

reduced. When all other factors are held constant, increased brush drag will result in greater film thickness with conse quent improvement in durability and hiding. Conversely, sometimes it might be preferred to have a lesser degree of brush drag for easier application (that is, the amount of time and effort in applying a paint to a specific area is reduced with a lesser degree of brush drag).
5.2 This test method provides a standardized brushout procedure for the evaluation of brush drag as an alternative to customary informal ad hoc procedures. Its objective is to maximize the reliability and precision with which this characteristic may be determined.
N' 1--The brush drag of paints is directly related to their,
high-shear viscosity. There is generally good rank order agreement between results obtained by this method and Test Method D 4287. Thei sensitivity of this brushout method has been found sufficient to distinguish between brushabilities corresponding to high-shear viscosity differences not lower than 0.3 poise (0.03 Pa.s). Round robin data show that rank order agreement between the brushout and viscometric methods is poor when latex and solvent paints are part of the same comparison group. This is the result of these two paint types having markedly different rheological properties that affect the relative percep tion of brush drag.'4

and rate the specimen as the mean of the two results. 8.10 If more than one specimen has the same rating,
brush out the similarly rated specimens again, in close comparison. If small differences are perceived, then indicate these by assigning intermediate decimal values. If no differ ence is found then the original ratings stand.
9. Interpretation of Results
9.1 Tabulate the paints in order of their brush drag ratings, showing verbal descriptions and numerical ratings in separate columns.
9.2 In a fourth rank order column, rank the paints from 1 to n (least to most brush drag), where n is the total number of paints in the series.
9.3 Paints with the same qualitative ratings should be assigned multiple rank numbers, with the mean of those numbers shown in parentheses, for example, 3 to 4 (3.5), 5 to 7 (6). The mean ranking value (in parentheses) is used to calculate an average ranking value when the same series of paints is ranked by more than one operator.

11. Precision and Bias
11.1 In an interlaboratory study of this test method in which five coatings varying widely in brush drag were ranked by one operator in each of nine laboratories, two operators in one laboratory, and three operators in another, laboratory, the coefficient of concordance (agreement in ranking) was found to be 0.84, reflecting the fact that seven ofthe fourteen operators agreed perfectly and four others reversed one of two adjacent pairs. The coefficient is statistically significant at the 99.9 % confidence level.

4. Summary of Test Method
4.1 The thermoplastic specimen is prepared for this test by melting a sample to its application temperature under continuous agitation and then pouring it' into a TFEfluorocarbon coated pah, to form a patty of approximately 3 in. (7.6 cm) in diameter. The patty is allowed to cool to room temperature before measuring the color. Color measure ments are made on the flat side or the top side of tU thermoplastic patty.
s,Auft1 if noo
N' 1--No significant color differences are encountered in reading
the top or bottom of the patty.
5. Significance and Use
5.1 This test method provides a standard procedure foi the determination of color of thermoplastic traffic marking materials. This test method can be used in conjunction with specifications to determine the uniformity of thermoplastic traffic marking materials from batch to batch and that produced by various suppliers.
5.2 There is a slight variation in color standards and colorimeters. This test method is only applicable when results are reported with the instrument model'designation and white color calibration standard identification informa tion.
6. Sampling
6.1 Samples may be obtained by an appropriate quar-, tering or riffle sampling method where deemed necessary considering the physical form of the material.
7. Apparatus
7.1 Agitator Blade, 6 in. (15 cm) long with a Vi-in. (1 -cm) steel shaft and a PA by I by Vs-iti. (4.5 by 2.5 by 0.3-em)' straight horizontal steel blade.
7.2 Drill Press, or other apparatus capable of agitating the thermoplastic marking material in the electric pots at 600 to 700 r/min during meltdown to the application temperature
7.3 Heating Equipment: 7.3.1 Gravity Convection Oven, capable of maintaining 260C, for melting the thermoplastic traffic marking. 7.3.2 Hot Plate, capable of maintaining 537<'C. 7.3.3 Insulated Electric Pots, for heating and melting the thermoplastic traffic marking materials. 7.4 Color Measuring Instrument, conforming to all re quirements of Test Method E 97, Practices E 179 and E 1164, and Method E 308 (geometry 45/0'\ illuminanl (, 2 observer). 7.5 Spatulas, for stirring the thermoplastic traffic marking

-8. Procedure
8.1 Taking care to prevent scorching of the material, melt :k ,1000 50-g sample of the thermoplastic marking material i'tTa temperature of 2I8C under continuous agitation, by !i e of the following means:
8.1.1 On a. hot plate set at 537C and using a spatula as

(ficient to reach the test temperature and with agitation of
0 to 700 r/min from an electric drill press or other suitable
eans.
: -
8,1.3 In an oven set at 260C with agitation by stirring
th a spatula after thefirst 15 min and thereafter at 15-riiin
tervals. The first stirring at 15 min is critical to' prevent
rehing of the thermoplastic marking material. The sample
ust be completely wet in on the first stir to ensure even
elting and complete blending of the components of the
rmoplastic material.
8.2 Pour the thermoplastic sample into a clean, T&&
orocarbon-lined pan, to form a 3-in. (7.6-cm) diameter
tty. If a TFE-fluorocarbon pan is not available, pour the
mple into an uncoated pint tin lid to form a 3-in. diameter
tty. Before pouring the patty, the sample must be agitated
11 to prevent settling of the components and to providea
smooth homogeneous surface for color measurement.
8.3 Allow the patty to cool to room temperature for a
" inimum of 30 min and not to exceed 45 min.
No t ' 2--A 30 5-min conditioning of the patty negates the initial effects of thermochromism.
8.4 Calibrate the,color measuring instrument with a white
calibration color standard according to the instructions
supplied by the manufacturer.
8.5 Remove the patty from the TFE-fluorocarbon pan
and read the color measurement values from the flat smooth
side. If a pint tin lid is used then read the top of the patty.
Without removing the patty from the sample port immedi
ately take three readings. Record only the third reading for
each y, x, and y value to further compensate for any
thermochromism of the thermoplastic marking material.
8.6 A small port adapter,, if available,, for, the color
measuring instrument of approximately% in. (19 mm), may
be used to negate the effects of,geometry and texture when
reading the patties. This will measure, in between small
surface imperfections, characteristic of thermoplastic traffic
marking.

7. Procedure
7.1 Prepare a hiding standard as described in 6.4, or use the standard supplied with the logicator test charts.
N' I --Strong colors were measured according to this test method using standards prepared with the self-same coatings. Some measure ments were also made using the regular white standard. Due to poor correlation in these tests it was decided to exclude strong colots from the scope of the test method. However, should measurements with such colors be attempted anyway, it is of interest to note that the white standard apparently served as well fdr that purpose as a standard made with the identical color.
7.2 Place a test chart on the vacuum plate. Then place the logicator at the top of the chart with its arms extending toward the operator.
7.3 Spread about 6 mL of the test paint evenly in front of the logicator, then draw down the full length of the chart (about 10 in. (254 mm)) at a uniform speed such that the total drawdown time is about 2.5 to 3 s.
7.4 Promptly after film application, determine the Wet Hiding Index (hsw) in accordance with 7.5.
7.5 Observation ofthe Hiding Index (hj: 7.5.1 Place the chart vertically in a well-illuminated glare-free location. 7.5.2 Hold the hiding standard next to the chart and identify by number the stripe that the standard matches in contrast. This number is the Hiding Index. 7.5.3 Ifthere is no exact match and it is difficult to decide which of two adjacent stripes is matched more closely, record their mean as the Hiding Index. However, if the standard is perceived as closer to one or the other of the two stripes, then report the Hiding Index as one more than the lower or one less than the higher, as the case may be. 7.6 Immediately after determining the Wet Hiding Index few), place the drawdown horizontally in a well-ventilated, dust-free location, as specified in Specification D 3924, and allow to dry for 40 to 48 h. Then repeat 7.5 to determine the Dry Hiding Index (ASD). 7.7 Make drawdowns in triplicate and calculate the mean index value to 0.1 units. Individual values that deviate from the mean by more than 1.5 units should be discarded and the test repeated.

a wide range in wet-to-dry hiding change. Since the test -.< not repeated,the repeatability data is only for replicates. On, this basis the intralaboratory standard deviation was 0.77 11f with 85 df and the interlaboratory standard deviation was, I. 97 LU with 39 df. Based on these standard deviations ifcfollowing criteria should be used forjudging the acceptability of results at the 95 % confidence level:
10.1.1 Repeatability {Replicate)--Three replicates by the same operator should be considered suspect if they differ by more than 2.6 LU.
10.1.2 Reproducibility--Two results, each the mean ut-triplicates, obtained by different operators should be consid ered suspect if they differ by more than 5.7 LU.
10.2 Bias--This test method has no bias because there is no criterion for the property it measures more valid than the test method itself.
N' 2--In the statistical analysis results were discarded on the following basis: (1) all results from one operator who appeared to be less sensitive than the other operators in detecting differences among triplicates, (2) one .replicate result from one laboratory because the. triplicate range was significantly higher than for other laboratories, and (3) all three results from the same laboratory for another paint, because the mean differed significantly from other means for that paint.

3. Significance and Use
3.1 This practice is intended to evaluate coating films for tlieir stability to ultraviolet light and moisture. If the spectral
power distribution of the light source used for exposure tests does not adequately simulate that for terrestrial solar radia tion, it may produce a different type of degradation and distort the ranking of materials obtained in outdoor expo sures, Figures I and 2 compare representative spectral power distributions of a twin enclosed carbon arc with that of terrestrial sunlight.
3.2 No single operating procedure for light-exposure ap paratus with or without water can be specified as a direct simulation of natural exposure. This practice does not express, or imply, a specific correlation with outdoor expo sure.
3.3 Since natural environments vary with respect to climate, geography, and topography, it may be expected that the effects of natural exposures will vary accordingly. Fur thermore, all materials are not affected equally by the same environment. Therefore, results obtained by use of this practice should not be represented as equivalent to those of any natural weathering test until the degree of correlation has been empirically established for the material in question.
3.4 Variations in results are possible between instruments bf the same type operating within the accepted limits of this practice. It is recommended that results obtained using this practice be compared with those for a control or reference material that is mutually agreed upon by the interested parties.
3.5 All references to exposures in accordance with this
practice must include a complete description ofthe test cycle
used in addition to the type ofdevice used.

Sunlight was measured in ' Phoenix, AZ, at the summer solstice with clear sky at sotor noon using a double grating monochromator (1-nm bandpass) with a quartz cosine receptor on an equatorial fbllow-the-sun mount. Because of momentary fluctuations In intensity due to flickering of the carbon-arc flame, the spectral power distribution shown In this figure is relative and is not to be used to calculate or estimate total radiant exposure for tests In enclosed carbon-arc devices.

4. Hazards
4.1 Precaution--In addition to other precautions, never look directly at the carbon arc because ultraviolet radiatiun can damage the eye. Most carbon-arc machines are equipped with door safety switches, but users of old equipment must be certain to turn the OPERATE switch OFF before opening the test-chamber door.
4.2 The burning carbon rods used in these devices become very hot during use. Make sure to allow at least 15 min for the arcs to cool after the device is turned off before

tent with the anticipated end use, or as mutually agreed upon gbetween the producer and user. I, 5.2 Panel specifications and methods of preparation in clude but are not limited to Methods D 609, Specification =J;358, or Practices D 1730. Select panel sizes suitable for use fj|fith the exposure apparatus.
5.3 Coat test panels in accordance with Test Methods 823 and measure the film thickness in accordance with an ippropriate procedure selected from Test Methods D 1005, '1186, or D 1400. Nondestructive methods are preferred
llpcause panels so measured need not be repaired. Prior to exposing coated panels in the apparatus,
Condition them at 73 3"F (23 2C) and 50 5 % relative
! uunidity for one of the following periods in accordance with
ffiic type of coating:

af-.*}, 6.1 Mount the test specimens both above and below a ^horizontal plane at the center of the single arc or centered pjbetween the two enclosed carbon arcs. When the exposure fc.interval does not exceed 24 h, locate each specimen equidis Eant from the horizontal plane at the center of the single arc
of centered between the arcs. if ' 6.2 To ensure uniform exposure conditions for all specigjtiiens, reposition them vertically within their holders in a j||gquence that will provide each specimen with equivalent pposure periods in each location. For exposure intervals not Exceeding 100 h, reposition specimens daily. For longer Wpposures, reposition specimens weekly. Other methods of
ff-acnieving uniform total irradiation may be employed if 3 ggnutually agreed upon between all concerned parties, i Ip, 6.3 Table 1 lists test-cycle conditions commonly used for
evaluation of paints, varnishes, lacquers, and related coat-
- JV' T}7` 6.4 It is recommended that the temperature of the water SLiised for specimen spray be 60 9F (16 5"C). Water used
for specimen spray must meet the purity levels specified in Practice G 23 in order to avoid unrealistic water spotting.
6.5 When mutually agreed upon, cycles other than those listed in Table 1 may be used. The term cycle is defined as the set of exposure conditions (light, light plus water spray, dark periods) that are repeated.
7. Periods of Exposure
7.1 Use one of the following methods to determine the duration of the exposure under this practice:
7.1.1 A mutually agreed upon specified number of total hours.
7.1.2 The number of total hours of exposure required to produce a mutually agreed upon amount of change in either the test specimen or an agreed upon control or reference material.
8. Evaluation of Specimens After Exposure
8.1 Evaluate or rate changes in exposed test specimens in accordance with Test Methods D 523, D 610, D 659, D 660. D 661, D 662, D 714, D 772, D 2244, D 2616, D 4214, E 97, and Practice D 1729. Consider product use requirements when selecting appropriate methods.
8.2 Evaluate test specimens by ranking their performance relative to a control or reference material exposed at the same time.
8.3 Plot properties of test specimens and controls as a function of exposure time and compare rate of change with that of the control or reference material. When this method of evaluation is used, the control or reference material must be exposed at the same time and in the same device as the test specimens.
8.4 Other methods for evaluating test specimens may be used if mutually agreed on by all interested parties.
9. Report
9.1 Report the following information: 9.1.1 Complete description of exposure procedure-used, including: 9.1.1.1 Light/light plus water/dark cycle used, type of device used (single or twin enclosed carbon arc), 9.1.1.2 Operating black panel temperature during ail portions of exposure cycle, 9.1.1.3 Operating relative humidity, and 9.1.1.4 Temperature of water used for water spray. 9.1.2 Total hours of test. 9.1.3 Test specimen preparation. 9.1.4 Identification of controls used. 9.1.5 Results of evaluation test or tests performed on specimens and control or standard samples.

Designation: D 5043 - 90
Standard Test Methods for Field Identification of Coatings1
This siandard is issued under the fjxcd designation D 5043; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the yearoflnst revision. A number in parentheses indicates the year of last rcapproval. A superscript epsilon (i) indicates an editorial change since the last revision or rcapproval.
1. Scope
1.1 These test methods cover procedures and portable apparatus for determining the generic type of coating Films most likely to be encountered on structures. The coating can either be weathered from exposure or be freshly applied.
1.2 Most commonly used coatings can be divided into the broad categories and subgroups shown in Table 1 on the basis of the nonvolatile component (generic types) of their vehicle .(film forming resin, binder). Although the curing, of some coatings involves more than one process and coatings may contain more than, one type of resin, they can usually be assigned to one of the basic classes and generic types listed in Table l,
1.3 For field exposed coatings, it is suggested that these test methods be used as part of a complete evaluation of a coated surface as it is frequently helpful to consider the environment of exposure and how the coating has performed in the environment when drawing conclusions from these tests..
1.4 These test methods will not result in the identification of components of a coating beyond general classification of the coating by generic type and are not appropriate if more detailed analysis is required, far example, as a part of failure analysis of to identify between different manufacturers of the same type of coating. They also may not be definitive enough to identify complex systems that include .multiple layers ofdifferent generic types of coatings.
1.5 The evaluation of results is quite subjective. Practice and experience are required to minimize misinterpretation. Repeat tests may be required..
1.6 None of the tests is to be taken alone as grounds for identifying the generic type. Only the combination of results from several or all of the tests are to be used in conclusions regarding generic types. .
1.7 This standard does not purport to address all of the safely problems associated with its use. It is the responsibility ofthe user ofthis standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use: For specific hazard statements, see Notes 8, 9, and 11.
2. Summary of Test Methods
2.1 Samples of coatings films are tested with solvents and chemicals and subjected to pyrolysis to provide evidence of their generic type. Figure 1 shows a flow chart for suggested order of tests and classification of results.
1 These test methods arc under the jurisdiction of ASTM Committee D-1 on Paint and Related Coatings and Materials and are the direct responsibility of Subcommittee D0J.46 on Industrial Protective Coatings.
Current edition approved April 27, 1990. Published June J990.
3. Significance and Use
3.1 Information about the generic type of coating on a surface is required to select compatible coatings for re painting and can be used when evaluating the performance of a coating in an environment in decisions on upgrading or replacing a coating system. These test methods provide information on generic type, can be performed in the field by personnel with limited laboratory experience, and require a minimum of equipment and materials.
4. Sampling
4.1 The sample of coating can be obtained by chipping < ( . scraping with a knife or by sanding and then brushing the material into a specimen container or clean envelope. Care should be taken not to cut into substrates, such as plastic or asphalt, that contain polymeric or bituminous materials Small portions of untreated wood, masonry, or steel do not ordinarily interfere with the tests. Some tests can be con- ' ducted directly on the coating surface. If a liquid sample of coating is to be evaluated, a film of the coating should first be * cast on a glass plate or similar surface from which it can conveniently be removed after drying.
N ' I--To develop familiarity with the subjective evaluations thaf'j;
follow; it is good practicelo make films of known resin composition by;
applying control paints to glass plates or similar surfaces from which;-
they can be readily removed after drying.
5. Pyrolysis
5.1 Summary of Test Method--A sample of coating:! placed in a small- test tube is burned over a hot flame. Thei way the coating burns and the odor and other characteristics of the- fume generated are recorded. The Beilstein test identifies the presence of chlorinated and other halogens. In coatings, chlorine-containing material is most often encoun-. tcred. For coatings not containing halogens, the odor is* recorded. .
5.2 Apparatus: 5.2.1 Flame. Source, including butane or propane utility torch. (Lighters do not provide a hot enough flame.) 5.2.2 Test Tubes--A suitable size is 10 by 75 mm (disposable culture tubes). 5.2.3 Copper Wire--A length of single-strand 16 to 18 gauge. AWG copper electrical wire, stripped of insulation sufficiently far that melted insulation cannot interfere with the test, is satisfactory. Leave about 6 in. of insulation as a heat insulator or provide a wrapping or handle for protection from heat. 5.2.4 Lead Acetate Paper. 5.2.5 Test Tube Clamp. 5.3 Procedure: 5.3.1 Put a small specimen of coating, preferably of one

N' 2--Melting, bubbling, and charring are common with most
generic types and not definitive.
5.3.2 Continue heating until fume (smoke) fills the test tube. Most fumes are white or near-white; slight condensa tion of a clear liquid on the upper test tube wall is sometimes observed. Other observations and identifications include:
Observation
Identification
Dark fume; clear brown liquid condensate Very dark, possibly sooty fume; dark condensate

N' 3--Bituminous coatings may be asphalt, coal tar, or combina
tions. The test is not definitive.
N' 4--Silicone coatings will form an ash upon pyrolysis at SOO'C.
Such temperatures are outside the scope of this test.
5.3.3 Beilstein Test--Conduct the Beilstein test by first heating the bare copper wire in the flame until no color is imparted to the flame. Insert the heated wire into hot fume in the test tube briefly (1 to 2 s). Withdraw the copper wire from the test tube and immediately hold it in the flame again. Observe the flame over the copper wire for color and
make identifications as follows:
Observation No color Traces of green color
Strong green color
Identification
no chlorine or chloride (or other halogen) content chloride contaminants from environment or minor
component of coating chlorinated resin or chlorinated resin modifier
With practice, the intensity of the green flame can be used to determine whether the chlorine containing component is major or minor.

5.3.3.2 Example 2--An intense or moderately intense relatively short-lived green flame, which may or may not be repeated, indicates chlorinated plasticizer in a nonchlorinated resin binder.
N' 5--Although fluorinated resins also give a positive Beilstein test, they are less likely to be encountered in industrial applications than
chlorinated resins. N ' 6--If the sample includes hydrated nraterial, for example,
concrete or plaster, water will be liberated by burning and will condense
on the wall of the test tube. Halogen liberated from the paint will be absorbed into the condensate. The copper wire must be brought into contact with the condensate to avoid a false negative.
N' 7---Those experienced with the Beilstein test may prefer to run it on a specimen not subjected to pyrolysis.
5.3.4 Odor Test--Conduct the odor test only if the Beilstein test is negative (no green flame).
N' 8: Warning--Hot chlorine or fluorine-containing fumes are. extremely irritating and potentially hazardous. Tip the test tube so that the fumes flow toward the open end of the tube. Gently wave a hand over the mouth of the test tube and carefully smell the odor of the fumes as they dissipate from the mouth of the test tube. Avoid overexposure to
the fumes.
5.3.4.1 Indications are subjective, but the following classes can be assigned:

5.3.5 Use the lead acetate paper to verify the presence of a
sulfide component by holding a piece of moistened lead
acetate paper over or in the mouth of the test tube. A
sulfur-containing component is present if the paper rapidly
darkens.
6. Solubility Tests
6.1 Chemically cured, inorganic, and aged oleoresinous coatings are not resoluble in the solvents originally used in producing the coatings. Lacquers and some latex coatings are resoluble and the strength of the solvent required to cause the coating to dissolve can be used to classify the coating.
6.2 Reagents--Solvents used, listed in order of increasing power of solvency (that is, ability to dissolve a resin), are as follows:
6.2.1 Denatured Ethanol (Ethyl Alcohol): 6.2.2 Mineral Spirits (Petroleum Spirits)--Aliphatic hy drocarbon solvent with typical Kauri-Butanol value (KB) of 25 to 45. 6.2.3 Xylene (Xylol)--Aromatic hydrocarbon solvent with typical KB of 98. 6.2.4 Methyl Isobutyl Ketone (MIBK, 4-Methyl-2-
Pentanone). 6.2.5 Acetone (Dimethyl Ketone, 2-Propanone). 6.3 Procedure: 6.3.1 Although a stirring rod or a gloved finger-tip can be
used, the test is best done by a finger-rub technique on the coating film itself. The sensations perceptible by touch are valuable in interpreting results. Alternatively, the solubility tests may be done by soaking portions ofthe film insolvents,
in which case porcelain spot plates and glass stirring rods can be used.
N' 9: Warning--These solvents can cause skin irritatio; L..( dermatitis, Minimize time of contact of solvents with skin and discon tinue use if irritation occurs.
6.3.2 Finger-Rub Test--Beginning with ethanol, dampen a fingertip and.rub the surface of the film briskly in a circular motion 5 to 10 mm (`A to V2 in.) in diameter. Renew the test solvent frequently as required. Continue rubbing at least 30 s or until definite effects are observed. Continue with each solvent in increasing power of solvency by cleaning the fingertip in each succeeding solvent before using that test solvent and selecting a new spot on the film or an untested chip of paint for each solvent used.
No t e 10---If the coating film on the test surface is chalky, the first fxnger-rub test done with ethanol will liberate much of the chalk, which will dry quickly on the finger as a powder. Repeating the test will reveal much less or no color and the test surface will appear unchanged. If a chalk is liberated, iise ethanol to clean the test spot for subsequent solvent tests.
6.3.3 Solvent-Soak. Test--The full series of solvents can bq

njn concurrently. Place five chips in a spot plate dish ,Lnd
pour a small amount of each solvent over one of the chips.
Periodically stir the solvent and rub the chip with a stirring
rod until definite changes occur. Add additional solvent, if
necessary due to evaporation, and observe extent of discolor
ation of the solvent and whether the chip softens, breads
apart, swells, dissolves, or a combination thereof. Note whether a color, different from the color of the topcoat is imparted to the solvent, indicating dissolution of an interme diate or primer coat. If portions of the chip dissolve or

Ifr-.NpTi '^rafcutmre
discolor the solvent, soak up the solvent with a paper towel
and add fresh solvent if undissolved chip remains. If no
further effect occurs, wash the remainder of the chip b\
gentle swirling, soak up the solvent, allow the chip to dr)',
and proceed with pyrolysis or other tests.
:fil
N' 11: Precaution--Do not attempt to bum a solvent-wet chip ojr'i
heat solvent in a test tube, as the liquid may suddenly boil, possibly ;; causing burns or loss of specimen.
6.3.4 Observe the effects of rubbing or soaking and classify as follows (the results for the soaking test are more difficult to interpret than for the finger-rub test):
6.3.4.1 No effect or small amount of color transfer to the fingertip or rod (due to chalk or film surface abrasion while rubbing).
6.3.4.2 Softening of the film, with resin rolling into small balls under the fingertip or rod.
6.3.4.3 True solubility with film dissolving, becoming sticky, and transferring in relatively large liquified quantity to the fingertip or rod.
6.3.5 Succeeding layers in a coating system may be individually tested if they are visually different; for example, colored topcoat, white or grey intermediate coat, and brown or red primer coat. To test visually different layers, repeat edly rub the spot with an effective solvent and wipe away dissolved coating periodically until a sublayer of different color is clean, then continue the test with the effective solvent on the sublayer. If that solvent is ineffective, repeat the test on the same spot with the next stronger solvent in the series. If that solvent is effective, repeat the test on a new

fcen or area, and when the sublayer is uncovered, allow gpivent to evaporate, then test the coating with the
St solvent in the series, continuing up the series until lity is again observed. If a sublayer of coating is not
by any solvent in the series, that layer may be |ted and collected by chipping or scraping for a sis test. || Interpretation ofResults: |i No Effect with Any Solvent--.Chemically cured, ed (aged) oleoresinous, or inorganic.

8.2.2 Medicine Droppers. 8.3 Reagent: 8.3.1 Sulfuric Acid, concentrated. 8.4 Procedure--Support the filter paper off surfaces that may be damaged or could cause interference in the test. A watch glass can be used to support the paper. Place a specimen of coating in the filter paper. Place 2 or 3 drops of sulfuric acid directly on the coating. Place 1 or 2 drops of acid elsewhere on the filter paper not in contact with the coating. Let stand for 1 to 2 min. Carefully hold and tilt the filter paper toward the vertical until the acid runs down the paper away from the specimen. Wait 10 to 30 s or until there is development of color in the acid itself, not on the coating.

8.5.1 If red to violet color develops in the drop of acid not
in contact with the specimen, then the paper is contaminated
or was placed on an epoxy or epoxy-coated surface. Discard
and repeat the test. A very slight pink color may develop in the acid. This is not a positive result. Bitumen-filled epoxies may discolor the acid enough to mask color development If
the acid stream is discolored brown to black, carefully rinse
the filter paper briefly in water or under running water if
available. Color from a positive test will remain in the filter
paper after the discoloration is washed off. The filter paper
itself will be charred brown by the acid and eventually
dissolve. The color of a positive test should occur early
enough to be seen before the paper chars.

9. Test for Pigments that Contain Lead and Hexavaient Chromium
9.1 Summary of Test Method:
9.1.1 Knowledge of the presence of pigments that contian
lead and hexavaient chromium in an existing coating system
may be important in a decision on whether the coating
system is to be retained and recoated or on the method of
removal and disposal of the coating system residue.
9.1.2 Pigments that contain lead or hexavaient chro
mium, or both, may be used both in primers as rust-
inhibitive pigments and in topcoats as weatherrresistant
colored pigments. Depending on the ease with which a
coating system can be separated, topcoats and primer coats
may be individually tested for lead or hexavaient chromium,
or both.
9.1.3 The presence of lead and hexavaient chromium
containing pigments can be qualitatively determined in the
field with the following two tests. Both tests can be done
directly on the coated surface or on chips or dust of the
coating placed in the well of a spot plate.
9.2 Apparatus--Glass beakers, jars or bottles, porcelain
spot plates, sandpaper, razor blade or knife.
9.3 Reagents:
9.3.1 Sodium Sulfide Powder or Crystals.
9.3.2 Hydrochloric Acid, concentrated.
9.3.3 Diphenylcarbohydrazide Powder.
9.3.4 Phosphoric Acid, concentrated (85 %),
9.3.5 Acetone.
9.3.6 Denatured Ethanol.
9.3.7 Distilled or Deionized Water.
9.4 Preparation of Test Solutions:
9.4.1 A solution of sodium sulfide in water is used to test
for presence of lead. Prepare the solution by dissolving 1.5 g
of sodium sulfide in 20 mL of distilled wattjr and adding
hydrochloric acid dropwise while swirling the solqtjon until a
white precipitate forms and remains with continued swirling
(pH should be about 8). A proportionally smaller or larger
amount of solution can be made up, The solution loses
strength with age. Test the solution by placing a drop on a
strip of lead acetate paper and. observing the paper for the
development of the black color of lead sulfide. If color
development does hot occur, discard the solution and make
a fresh one.
`
9.4:2 A solution of 1,5-dipheijylcarbohydrazide is used to
test for the presence of hexavaient chromium. Prepare the
solution using the following or proportionally smaller
amounts of ingredients. Dissolve 0.5 g of 1,5-
diphenylcarbohydfazide in a mixture Of 20 mL acetone and
20 mL ethanol in a beaker, warming the beaker in warm
water if necessary to facilitate solution. Carefully add 20 mL
of phosphoric acid to 20 mL of cold distilled Water in a
separate container. Slowly add the acetone-ethanol mixture
to the dilute acid solution and mix thoroughly by swirling.
The 1,5-diphenyIcarbohydrazide solution is not stable. It
may be stored for short periods of time in an opaque glass bottle but is best prepared just prior to use. The solution can be tested by placing a drop on a material known to contain a hexavaient chromium pigment. If a blue to violet color does not rapidly develop in the drop of solution, discard V solution and .prepare a fresh solution.
9.5 Procedure:
9.5.1 Abrade two separate spots on the coating film with sandpaper or knife if the tests are to be done on the coatii g
surface. Alternatively, abrade one spot of the coating and collect the dust and flakes in two wells of a spot plate. Abrasion of the film is required to expose pigments in an
aged, weathered film.
9.5.2 On one abraded spot or on the specimen in one well of the spot plate, place 1 or 2 drops of sodium sulfide solution. Development of a black or dark grey color on tin film or flakes indicates the presence of lead. Lack of color development indicates less than 0.1 % by weight lead (ap proximate practical limit of sensitivity of this test procedure).
9.5.3 Metals other than lead give a positive sulfide test bi; may 'not be common to coatings or usually do not interfere in this test in the form present. If there is doubt, laboratory'f testing beyond the scope of this test method isrequired ta; ' confirm the presence of lead:
9:5.4 On one abraded spot or to the second well of 1
spot plate place 1 or 2 drops of 1,5 diphenylcarbohydrazid solution. Rapid development of blue to violet color in tie solution droplets indicates the presence of hexavaient chro- " niium. r
9.6 Interpretation ofResults--The /combination of results; from the two tests, together with consideration of the color ot the coating, may be 'used to establish more definitely the''
pigments that are present, as shown in the following scheme, which is not all inclusive:
Observation Positive for lead, negative for chromium Negative for lead, positive for
chromium Positive for lead, positive for chromium

The pooled within-laboratory standard deviation was found to be 3.25 % of the value measured with 12 df. The between-laboratory standard deviation was 7.63 % of the value measured with 28 df. Based on these standard devia tions, the following criteria should be used for judging the acceptability of results at the 95 % confidence level.
11.2 Repeatability--Two results, each the mean of dupli cate determinations, obtained by the same operator should be considered suspect if they differ by more than 9.19 % of the value measured.

Standard Practice for Conducting a Patch Test to Assess Coating Compatibility1 2
This standard is issued under the fixed designation D 5064; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This practice covers the procedures for testing coating compatibility when maintenance of an in-place coating system is being contemplated. It does not cover procedures for assessing the integrity of the existing coating to determine if it can be repainted, nor does it establish the compatibility of the maintenance coating system with the substrate or corrosion products. The practice is intended for use in the field.
N' 1--Pass-Fail Criteria (for example, adhesion requirements) are
not established by this practice. These should be established by the user or specifier with input from the supplier.
1.2 This standard does not purport to address the safety problems associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

visual defects and adhesion is determined.
5. Significance and Use
5.1 In performing maintenance of a coating system, the new coating being applied must be compatible with the existing coating. While general guides exist which indicate compatibility of different generic types of coatings, differ ences in manufacturer's formulation and the condition ofthe in-place coating will affect compatibility.
6. Procedure
6.1 Select test locations for evaluation that properly char acterize differences in configuration of the structure and exposure, that is, vertical versus horizontal surfaces and bold versus sheltered exposure. A minimum of three test locations with one test patch in each is recommended.
6.2 The size of each test patch will be determined by the size and configuration of the test locations. Each test patch shall be as large as possible, with a minimum size of 10 ft2 (0.93 m2) recommended.
6.3 Clean the surface of the test areas using the methods specified for the maintenance painting procedure (Note 2). Alternative methods of preparation may also be evaluated in separate, adjacent tests.
N' 2--This test method assesses compatibility with the existing
coating only and does not apply to areas where the substrate is exposed by the methods of preparation.
6.4 Measure the existing coating thickness in accordance with Test Methods D 1186, D 1400, or D 4138, as appro priate for the substrate.
6.5 Measure the ambient conditions and surface temper ature and assure the conditions are within the limits specified by the coatings manufacturer for the product being tested.
6.6 Apply the test coating to the thickness recommended for the particular job. Use the application technique as intended for use on the full-scale job. If agreed upon between the purchaser and the seller, the method of coating applica tion may be different from that used on the job, that is, brush application of the test patch even though spray application will be used on the job. However, this can cause some error and is not generally recommended.
6.7 Immediately after application, measure the wet-film thickness in accordance with Practice D 4414. Make correc tions to the application, if necessary, by either applying more material if the expected dry-film thickness is low or applying another test patch if the expected dry-film thickness is above the recommended maximum. Inspect each patch for appli cation defects such as runs, sags, and holidays. If such defects cannot be corrected as a part of the initial application process, prepare a new test patch.
6.8 After the coating has dried, measure the dry-film

thickness in accordance with Test Method D 1186, D 1400, or D 4138.
N' 3--When using Test Methods D 1186 or D 1400, the dry film sickness is the difference in average thickness of the coating system less
the average thickness of the in-place coating.
6.9 Allow the coating to cure or weather prior to testing. Cure durations are defined as long term and short term. Long-term curing provides the most reliable assessment of compatibility. Short-term curing provides for more rapid evaluation of results.
6.9.1 Long-Term Curing--Curing for as long a time as possible, with a minimum of six months preferred. Curing should span seasonal weather changes.
6.9.2 Short-Term Curing--Curing at the following min
imum times based on average daily (24 h) temperatures:
50`F(10"C)
70F (21"C)
90`F (32`C)
14 days
10 days
7 days
6.10 After curing, examine the total surface of each test patch for wrinkling, blistering, mudcracking, checking, cracking, peeling, lifting, and disbonding. Measure or rate
the adhesion in a minimum of five locations per test patch in accordance with Test Methods D 3359.
6.11 Examine the test patches for the defects noted in 6.10 on a regular schedule, discounting rust caused by previous tests such as adhesion measurements and destructive film thickness measurements.
7. Report
7.1 Report the following information: 7.1.1 The identity of the structure tested, the location and size of the test patches, the identity of the test coating, the method and grade of surface preparation, and the method of coating application. 7.1.2 For each test patch, the dry film thickness measure ments and average of the in-place coating, the dry film thickness measurements and average of the test coating, the elapsed time for each evaluation, the visual defects noticed, and the results of adhesion tests.

A form for recording the results of die assessr, fq procedure (Fig. 1) is provided.
4. Significance and Use
4.1 Assessment of the condition of aged coated suit; strengthens decisions on when coating maintenance :s quirpd, aids in the selection ofeffective coating maintenance! procedures, and provides a means to characterize perionranee of coating systems.
5. Procedure
5.1 Survey the structure to (2) determine the general t of unique components (for example, for fuel tanks components may be shell, roof, ladders, and piping) and dw service exposure environment for each, (2) visually identify I areas having a typical level of coating deterioration and ru't ] breakthrough for each component and (i) identify areasJ having a much greater visual level of deterioration thaiil typical and unique environmental conditions that may j correspond to these areas (for example, bridge expansion' joints). Record a description of the components and their? general environment on an inspection form and describe areas having greater deterioration, as well as any unique^ associated environments in the remarks column. A suggesfod> general format for data collection is shown in Fin. i Modification of the form (for example, adding or dele specific items) will be required for each specific application.
5.2 Based upon the knowledge of what constitutes typ 11 1 deterioration for each component as determined in the iniiiu! survey, examine the condition of the coating on a represeit|j tative sample of each component. Rate the condition of the?| coatings using the appropriate ASTM visual standard for riistj breakthrough (Test Methods D 610), blistering (Test Methqdiil D 714), peeling (use Test Methods D 610 to report amount), chalking (Test Methods D42I4), and cracking/checkift$j (Test Method D 660) of the coating film.

18.1 Transfer efficiency measurement requires that accu-
i measurements be made ofthe quantity of paint material ed in the application process during the time period ociated with the coating of specific vehicles or parts. Two neral procedures are applicable for accurately measuring fit usage. 18.1.1 The preferred procedure is to determine the weight paint used during the application study period. Under pical production conditions, such weighing may be diffijlt, due to the large number of applicators requiring paint
iipply from a common tank. If a separate, isolated paint apply tank is used in the test; it is important to control paint
cosity, temperature, and flow rate consistent with the
liar production system (see 9.1). 8.1.2 Where direct paint usage measurement by weight is at practical, an alternative procedure for determining paint ge by volume is suggested. This procedure involves asuring the drop in paint level in the paint supply tank
9.2.5 Calibrate the weighing device in accordance with manufacturer's instructions. Weigh and tare a lifting frame, if used to support the satellite paint supply tank.
9.2.6 Weigh the satellite paint supply tank before the test vehicles or parts are run. Flexible connections are required to minimize strain. Carefully note the configuration of the tank so that the same configuration is used for both initial and the final.weighing (that isvhose connections, height, etc.). Weigh the tank until 2 consecutive measurements are obtained within the measurement error of the weighing system 0.05 lb (0.02 kg). Average the two readings. The satellite tank may
be left on the weighing device during the painting operation
to monitor painting usage on a continuous basis. 9.2.7; After painting the test vehicles or parts, reweigh the

requires that the drop in the liquid level in the system supply
is tank be measured accurately. This procedure is applicable
e- Paint Usage Determination by Weight Procedure
with either a satellite system or a main-mix room supply
9.1 This procedure for determining paint usage during the
Safest is preferred when a satellite paint supply system is
' ailable for the process to be tested. With this procedure, it ! usually easier to isolate paint usage for measurement ^purposes, and accurate results can be obtained with a smaller
system. A sufficient number of parts must be processed in the test block to provide at least a 3-in. (7.6-cm) drop in the
liquid level in the paint supply tank. Careful measurement is critical to the overall accuracy of the transfer efficiency test.
This procedure consists of the following: 10.1.1 Accurately measure the inside diameter of the
paint supply tank(s) to be used for the various test materials.
Electronic digitizer. Model 5322, available from Sterling Scale Co., 20950 Bocoirigi Southfield. Ml 48075, has been found suitable for this purpose.
If the agitator shafts, fill pipes, or any other objects are located in the measurement zone, the occupied volume of
921
DUP050298101
5066
these items must be determined and subtracted from the total volume. Careful selection of the section of the tank for the test measurement will minimize the difficulty of this task. The measurements are used to develop a conversion factor between level drop and volume of paint.
10.1.2 Most main paint supply systems consist of two tanks connected together to maintain the material supply. During the test, the paint supply tank must be isolated. Check to ensure that there is no leakage or overflow between the two tanks and that the directional valves for paint return function properly. Make sure that these checks are made just prior to and after the test, and are done by measuring the volume in both tanks.
10.1.3 Place the test paint, which has been reduced to spraying viscosity, into the paint supply tank to be measured. No material additions or reductions may be made to the tank during the test. Before the test is conducted, make certain that valving is set so that paint is being drawn from the test tank and returned to the test tank, and that all air has been removed from the delivery system.
10.1.4 With satellite paint supply tank systems, special care must be taken to ensure that all fluid lines are completely filled.
10.1.5 Prior to taking the volume measurement, turn off any agitation within the tank that will interfere with the measuring process and then turn it back on after the measurement.
10.1.6 Record the tank levels before and after the test. Take the initial reading just prior to the first test vehicle or part of the block that enters the first application station in the tested process. Take the final reading just after the last vehicle or part has left the last application area in the tested process.
10.1.7 With clearcoat (or other paint materials that cannot be isolated to a specific block of cars due to other connected operations such as repair), take the initial reading as the first vehicle or part in the test block enters the first station applying clearcoat. Take the final reading when the vehicle after the last job in the test block enters the first station, applying clearcoat (the same point at which the initial reading was taken). If this is not done, the block size for clearcoat will be different from the block size for basecoat (this is acceptable but must be accurately reflected in the calculations).
10.1.8 The measurements are to be taken to the nearest '/i6 in. with a measuring stick with Vis-in. (!.6-mm) or less graduations. Measurements are made from the top of the tank to the top of the liquid level at least 3 to 4 in. (7.6 to 10.2 cm) from the sides of the tank. The top of the tank is to be determined by laying a straight edge across the top of the tank in the same position for each measurement.
N' --Caution--Any measuring instruments used in this procedure
must be effectively grounded before contacting the coating tank or
coating liquid surface. Review all measuring instruments for suitability
and resistance to the paint solvents prior to the test.
10.1.9 It may be necessary to provide two-way radio communication between the mix-room monitor and the tested process operation to coordinate the measurement process and timing.
10.1.10 Obtain representative paint samples immediately
after completion ofthe test for density and solids determin tions.
11. Paint Solids Deposited Measurement Procedure
11.1 To determine the transfer efficiency, it is necessary determine both the weight of paint solids sprayed per vehii or part and the weight of paint solids actually deposited on the object in the tested process. These are obtained weighing vehicles or parts incorporated in the same sairmfi (block) used to obtain the paint usage measurement. *
11.2 Vehicle or Pan Weighing Procedure--The weight paint solids deposited during 'the application proo-j determined by weighing the vehicle(s) or part(s) prior to and after the paint is applied and baked. At least two vehicles o parts are required to be tested. A control part is also run j.* weighed before and after the application process. No painr applied to the control part in the process. The control required to determine weight loss from miscellaneous matef rials (primarily sealants and plastics applied prior to the tested process) that may occur in the drying oven. I difference in the weight of the measurement vehicles justed for the weight loss in the control vehicle or part, is weight of paint solids applied in the tested process.
11.3 Weighing of the parts requires the use of a precision weighing device and digitizer as described in 7.1 and 1 ' \ lifting frame and hoist are required to support the test vehicle. The measurement site(s) must be selected to avoid disturbance caused by air movement or production activities and to allow convenient removal of the test vehicles or parts from the production line and their subsequent replacement to the production line. Fork trucks or other mechanical handling aids along with sufficient manpower to move file vehicle bodies into and out of the weighing frame will bef required.
11.3.1 Passenger car bodies generally will weigh 800 to, 900 lb (364 to 409 kg). Since the maximum capacity of the' specified load cell is 1500 lb (682 kg), the weight of the lifting frame and rigging must be kept to less than 600 lb (273 kg) or a higher capacity load cell with the specified accuracy must be utilized.
11.4 It is critical that the vehicles or parts be allowed to cool completely to room temperature prior to weighing. Closely monitor heavy-metal sections (usually around the! door frames) as these areas will cool more slowly than.; exterior body surfaces. If during the weighing process there is any doubt that the vehicle or part is fully cooled, weigh the test part and allow it to stand 15 to 20 min and weigh again! If a weight increase of more than 0.05 lb (0.02 kg) is noted, allow the body to cool an additional 15 to 20 min and repeat the weighing procedure. Repeat this process until consistent weights are obtained.
11.5 Check that all accessories and miscellaneous mate rials (hangers, spacers, etc.) remain in the' same position (either on or off) for both the initial and final weighings.
11.6 Weighing Procedure: 11.6.1 Turn on the weighing device and digitizer and allow them to warm up in accordance with the manufactur er's instructions. 11.6.2 Zero the instrument in accordance with manufac turer's instructions. 11.6.3 Attach the lifting frame to the load cell. Lift and

Measurement of Other Paint Usage
reous mate- 2.1 When the measurement of paint used cannot be com-
me positionj Jtely isolated to the application process under test because of
eighings.
Ee process and facilities arrangement, it may be necessary to
Stain an estimate of paint solids deposited from the same igitizer and1' Tmt supply system in the nonisolated operations (such as nanuface .J |)air, etc.). With this estimated value, the total paint solids
|posited in the main process can be directly correlated to the h manufac-j rtount of paint used in calculating the resultant transfer
|ciency. Such a correlation can be established by either ill. Lift and ] king a separate estimate or measurement of the paint used
or the paint solids deposited outside the tested process. The amount of material involved should be small (less than 5 %} relative to the total paint used or deposited.
12.2 While an estimate of paint used is generally pre ferred, in practice it is usually easier to obtain an estimate of the amount of paint solids deposited onto the test unit. For
repair type operations, an estimate of paint solids applied may be obtained by counting the number of panels repaired while the test block is being processed and multiplying by the square feet per panel and the average film build applied (determined from measurements or historical data). This technique works well since almost all repairs involve com plete body panels for which data can readily be obtained.
13. Analysis of Paint Samples
13.1 Make the following analytical determinations for each paint sample obtained:
13.1.1 Weight Fraction Solids, in accordance with Test Method D 2369 per EPA Federal Reference Method 24.
13.1.2 Paint Density, in accordance with Test Method D 1475.
13.2 These determinations are required to calculate transfer efficiency. Obtain separate determinations for each paint material used in each test.
14. Calculations and Report Submission
14.1 Upon completion of the test and receipt of the paint analytical results, the transfer efficiency calculations can be made in accordance with the following procedure:

composition is available it may be used for this test instc. d
preparing a standard.
*
7.3.2 Dilute the watercolors with water and drawdown on
paper until the spectrophotometric measurement of thedrai'u
paint shows from 35 to 45 % reflectance at the wavelength maximum absorption for that pigment. The wavelength X *
maximum absorption is located at the point of lowest ^
reflectance on the spectral curve between 420 and 620 nm If"
using a tristimulus filter colorimeter, the lowest of the three
filter readings is the region of maximum absorption and the '
dilution should be adjusted so that a reading of 35 to 45 %
reflectance is obtained with this filter. The diffuse wh'-
reference standard for all measurements should have an
absolute reflectance between 97 and 100 %.
7.3.3 Use an applicator with a 3-mil (75-jj.m) aperture to
make a drawdown on the filter paper. Tape the filter paper to'J
a smooth surface such as a piece of glass. Place the ..
drawdown bar just above the upper edge of the paper so it is 3
ready to use. Pour a small amount ofthe diluted paint, which
is thoroughly mixed, onto the top of the filter paper. Using
the drawdown bar, draw the paint down, running the excess
offthe edge ofthe filter paper at the bottom. Quickly untape
the filter paper and hang it to dry at room temperature.
There will be a dark puddle area where the paint was
originally applied, but the remaining part of the paper will be
uniform in color for use in obtaining spectrophotomeli'
measurements.
7.3.3.1 Prepare four specimen panels for each pigment
under test. Two are used in the first lightfastness tests and, 1
two are retained in subdued light, one for visual comparisons
with the exposed panels and one in case a third test is needed
to supplement results from the first two tests, as described 11. Test Methods D 4303.
133.2 Apply the test paints to the filter paper as de
scribed in 7.3.3. The panels should be air dried for 2 h and
then put in an oven at 50C for overnight drying.
7.3.3.3 Cut the uniform color section of the filter paper
drawdown panel into I '/2-in. (38-mm) square panels. Adhere
the panels to the light posterboard (see 7.2.3) using a th
coat of an acrylic-latex adhesive. The size of the posterboard
shall conform to the dimensions of the exposure equipment
test racks.

A number in parentheses indicates the year of last rcapproval A superscript epsilon (t) indicates an editorial change since the last revision or reapproval
1. Scope
1.1 This practice describes the preparation or breaking-in of paint-roller covers for evaluation.
1.2 This practice is applicable to paint-roller covers having nap lengths up to Vi in. (13 mm).
1.3 This standard does not purport to address the safety problems associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.
2. Summary of Practice
2.1 Using the paint chosen for the evaluation, the paintroller cover to be tested is repeatedly and generously loaded with paint and painted out over the same area of approxi mately 4 to 6 ft (0.4 to 0.6 m2) until it is saturated with paint, that is, the paint-roller cover cannot pick up any more paint, nor apply any more paint to the area being used for break-in.
3. Significance and Use
3.1 Until a paint-roller cover is saturated with paint, only part of the paint loaded onto the paint-roller cover can be transferred to a surface being painted. The remainder of the paint is absorbed into the fabric of the paint-roller cover. The amount of paint absorbed by a paint-roller cover is inversely proportional to the amount already present within the paintroller cover. By saturation of the paint-roller cover before testing, quantitative inaccuracies of the amount of paint de livered to a surface are eliminated.
3.1.1 Using a saturated paint-roller cover enables the user to apply paint at controllable spreading rates.
3.1.2 Using a saturated paint-roller cover affords repro ducibility when repeating a test.
4. Apparatus
4.1 Paint Tray. 4.2 Paint Roller Frame, of the same size as the paint-roller cover being prepared.
5. Materials
5.1 Paint, to be used in test.
5.2 Primed or Painted Surface, to be used for the rollers cover break-in.
6. Procedure
6.1 Place the paint-roller cover on the frame. 6.2 Load the paint-roller cover with the paint from' tray by rolling the paint-roller cover over the surface oft paint so that just the nap is submersed. See Fig, 1. 6.3 Roll out the roller cover on the surface being used: break-in in an upward and downward motion in no larger, area than 2Tt. (0.6 m) high by the width of the roller cov.-r' 6.4 Reload the paint-roller cover with paint and roll oui in the same manner over the same area. Do not increase; area except as necessary to control excess dripping of pain 6.5 Repeat the above procedure as necessary until following conditions are met: 6.5.1 Reloading the paint-roller cover does not result in j increased paint pickup. 6-5.2 There is so much paint on the surface being used'! that the fully loaded paint-roller cover cannot transfer ; more paint to the surface. 6.5.3 When the above conditions are met, there will be much paint on the roller cover that constant movem< (turning over) is necessary to prevent dripping, and the pane will show profuse sagging of the paint. About six roller-cotei loadings are usually necessary to achieve this. 6.6 The roller cover is now prepared for immediate testing.

3. Summary of Test-Method
3.1 This test method simulates the loss of VOC from freshly coated surface by using the difference in weight of a coated test panel before and after baking. Metal test panels are subjected to a simulation of the production coating process including application, flashing, and baking. Th weight loss value obtained is then related to the volume solids deposited on the test panel to compute the number < pounds of VOC per gallon (grams per litre) of solids appliethat is available at the inlet of the VOC control device.
3.2 The information needed to determine the amount < VOC available for removal by the VOC control device is determined by identification of the points in the production!
process at which coated objects would enter flashoff/bakin zones whose effluents are vented to the VOC control device,1
4. Significance and Use

11. Precision and Bias
*
11.1 The precision estimated for this test method is basef
on an interlaboratory study in which one operator in each
five laboratories tested in triplicate on two different days lour-
water repellent materials containing between 14 to 65
nonvolatiles. The results were analyzed statistically in ao.\n-'
dance with Practice D 3980. The intralaboratory stan
deviation was found to be 0,283 % absolute with 17 df ami,**
the interlaboratory coefficient, of variation 7.02 % relmivey.
with 16 df. Based on the standard deviation and coefficiai; .
of variation, the following criteria should be used for judging*'
at the 95 % confidence level, the acceptability of results. '1'
11.1.1 Repeatability--Two results, each the mean ofj riftll
licates, obtained by the same operator should be considi icc'J,r
suspect if they differ by more than 0.84 % absolute.
*
11.1.2 Reproducibility--Two results, each the mean t
triplicates, obtained by operators in different laboratories *-
should .be considered suspect if they differ by more thaa|j
7.02 % relative.
11.2 Bias--Bias has not been established for this :.$G

7.3.3 Application ofGround Coats: 7.3.3.1 Degrease aluminum substrates before applying the
ground coat. 7.3.3.2 Apply one coat of the enamel described in 7.3.1.1,
followed by one coat of the enamel described in 7.3.2. To flow coat the aluminum panels for sun exposure use a 1-in. (25-mm) soft hair brush. Coat the postetboard to be used for laboratory exposure on the less absorbent, glossy side.
N+,' 4--Coating the posterboard is most conveniently done on the
whole sheet before cutting to size.
7.3.3.3 Allow a minimum of five days drying time fol lowing the first coat and two weeks or more after applying the second coat and before applying the paint to be tested.
7.4 Mixing Whites for Dilution ofColors: 7.4.1 Use a white containing the same emulsion and additives as the formulation in which the pigment is incor porated if possible.11 The following basic composition has been found satisfactory:

Acrylic emulsion nonvolatile
Rutile titanium dioxide9 (conforming to Type II of Specification D 476)
23 to 24 34.6
7.4.1.1 Keep the viscosity ofthe mixing white to 250 P or
slightly lower. 7.5 Preparation ofTest Paints: 7.5.1 The pigment to be tested may be milled in a
compatible paste for acrylic emulsion. If a prepared artists' paint of known composition is available, it may be used for this test instead of.preparing a dispersion.
7.5.2 Dilute the pigment paste or paint with the white
containing the same type of vehicle until the spectrophoto-
metric measurement of the dried film shows 35 to 45 % relative reflectance at the wavelength of maximum absorp
tion for that pigment. The wavelength of maximum absorp tion is located at the point of lowest reflectance on the spectral curve between 420 and 620 nm. If using a
tristimulus filter colorimeter, the lowest of the three filter readings is the region of maximum absorption and the dilution should be adjusted so that a reading of 35 to 45 % reflectance is obtained with this filter. The diffuse white reference standard for all measurements should have an absolute reflectance between 97 and 100 %.
7.5.2.1 To obtain this reflectance, use the Kubelka-Munk

7.5.3 Make instrumental readings with the specular refltc,
tance included to minimize the effect on readings of anv'
change in gloss and to minimize the effect of brush strain
7.5.4 Use an applicator with a 6-mil (150-pm) aperture to
make a minimum size drawdown, 1 'A by IV2 in. (40 by -i
mm), or other minimum size appropriate for the viewin'
area of the instrument used. Return all recoverable paini tu
the batch to allow for repeat mixes and measurements.
7.5.5 For acrylic emulsion paints, 80 g of white paint is|j|j
needed since paint used in the drawdown is lost.
`*
7.5.6 For the initial weights of white stated in 7.5.4 :)n,_ j
7.5.5, the weighing must be accurate to 0.05 g.
7.6 Application ofPaints to Panels:
!
7.6.1 Prepare four specimen panels on appropriate sufi.'#
strates for each pigment under test. Two are used in the first `
lightfastness tests and two are retained in subdued light, one
Jfor visual comparisons with the exposed panels and one in 1
case a third test ismeeded to supplement results from the first
two tests, as described in Test Methods D 4303.
7.6.2 Apply the test paints by brush to the alurainuffii'sd
panel if exposure is to be under glass to the sun or by brusftJS
to the posterboard panel if exposure is to be to laboratory i
apparatus.

7.6.3 Using the No. 12 artist's flat bristle brush, brush the "1
panels lengthwise, then crosswise, and again lengthwise, ttus^J
time with a light touch to produce a film as smooth aPp
possible. The mixing whites must be fluid enough m
facilitate leveling, but not have excess vehicle that can aii'cct* j#

= Kubelka-Munk Value, = reflectance measurement of the mixture, made
with the specular component included ex pressed as a decimal value, and = decimal value correction for surface reflectance.
X2. [--To speed drying, accelerated methods may be used. It is |mmended that water-based acrylic paints be warmed to 50 to 55"C
t h after 1 b of air drying before measuring tire reflectance. Placing drawdowns of oil paints near fluorescent lamps, for example in the I? jfescent light exposure racks described in Annex A1 of Test Methods 003, will speed their drying time.
2.1.2 Calculate the Kubelka-Munk absorption coeffiSit for unit concentration as follows:
Kc - (K/S)JCc
|re Kc = unit absorption coefficient. 2.2 Based on the results of the trial mixture, calculate I concentration of colorant in white required to give the
desired 35 to 45 % reflectance at the wavelength of max imum absorption as follows:
Cd = (/f/5W^c = 0.4500/^.
where Cd -- concentration of colorant in white predicted to give a paint with the desired 35 to 45 % reflectance value.
X2.3 Adjust the concentration of the trial batch so that the concentration of colorant equals Cd. Determine the changes in colorant concentration, AC as follows:
AC = Cd -- C0
These changes are positive ifthe trial batch has a reflectance greater than 40 % and negative if the reflectance is less than 40 %. If AC is positive, add more colorant to the trial batch to bring the concentration of colorant to Cd. If AC is negative, add more white to bring the concentration of colorant to Cd. Because it may be necessary to add large
amounts of white to correct for concentrations of colorant giving reflectance values far below 40 %, it is usually best, to prepare a trial batch expected to give a AC value..that is moderately positive or only slightly negative.
X2.3.1 For the case where AC is positive, the weight of colorant needed to prepare a second batch is,
AWC=*WC- Ca(Ww + KQ/Q - I x (L.F.)
where:
AWC = weight of colorant to be added to the trial batch to
obtain a corrected batch with a colorant concentra tion of Cd, and
L.F. = "loss factor" = weight of paint from trial batch used
to prepare the corrected batch/weight of paint prepared as trial batch. The loss factor, L.F., allows for paint removed to prepare drawdowns, loss by transfer to different containers, etc. This term may be neglected if losses are small compared to the batch size. The other terms are as defined in the previous sections of this appendix. X2.3.2 For the case where AC is negative, the weight of white needed to prepare a corrected batch corresponds to,
AW,, = WC-
+ Wc)/Cd X (L.F.)

mmmtmL
DUP050298125
D 5098
where A W,, = weight of white needed to adjust the colorant concentration in the batch to Cd. Other terms are as defined above or in previous sections of this appendix.
X2.4 Prepare a paint film from the adjusted batch. After drying, measure the reflectance at the wavelength of max
imum absorption. If this value does not fall within 35 t(*
45 %, repeat X2.3 through X2.4, where C, now becomes ftfe Cc for the next batch correction. Normally only a
iteration is necessary and a second batch correction will no * be needed.

recommendation. See also Test Method D 4263. 4.2 Localized staining (for example efflorescence and
metallic staining) and previously applied coatings or preserv ative treatments not compatible with the treatment may require removal by other surface preparation methods.
4.3 Water cleaning, detergent water cleaning, and chem ical cleaning should notbe performed at temperatures below 40F.
4.4 Many chemical cleaning products contain acids and should be handled according to manufacturers' recommen dations. Use and" disposal of materials should conform to established federal, state, local, and project requirements.
4.5 If pressure washing equipment is employed for water cleaning or for flushing the surface With detergent water cleaning or chemical cleaning, the minimum effective pres sure should be used. Avoid excessive pressures that could damage the sandstone substrate.
5. Procedure
5.1 Air blast, water, scrubbing, sweeping, or vacuuming are acceptable cleaning methods. Chemical cleaning agents may be used to Temove surface deposits such as soot, fly ash, and hydrocarbon residues not removed by any of the above methods. Chemical cleaning should be preceded arid fol lowed by a thorough fresh water rinse.
5.2 Existing conditions of the substrate will determine the selection of appropriate procedure(s). Prior to the initiation of cleaning, small test areas should be cleaned in inconspic uous areas by the selected procedure to determine effective ness.
5.3 The six types of cleaning procedures are described below. One or more of the procedures may be required to remove contaminants from-the sandstone surface:
5.3.1 Broom Cleaning--Removes most loosely adherent solid contaminants.
5.3.1.1 Working from top to bottom, sweep the surface with a clean industrial stiff-bristled broom or similar device. Remove sweepings from the immediate work area.
5.3.1.2 Clean broom-cleaned surfaces again using one or more of the surface preparation procedures specified in 5.3.2 through 5.3.6.
5.3.2 Vacuum Cleaning--Removes surface dust and other debris.
5.3.2.1 Vacuum the surface with a heavy-duty type indus trial vacuum to provide an essentially dust-free surface.
5.3.3 Air Blast Cleaning--Removes debris, dust, dirt, loosely adherent architectural sandstone, and laitance from walls to provide an essentially sound, dust-free surface.
5.3.3.1 Clean surface with a compressed-air stream through a blasting nozzle held at an oblique angle approxi mately 2 ft (0.6 m) from the surface. Air stream pressure

should not exceed 100 psi (689 kPa).
5.3.3.2 Before initiating air-blast cleaning, verify that the
air stream is free of oil in accordance with Test Method
D4285.
5.3.3.3 Surface cleanliness is dependent upon carrying off
airborne dust before it is redeposited. Vacuum cleaning may
be required to remove redeposited dust.
5.3.4 Water Cleaning--Removes dust, dirt, and water-
soluble surface contaminants.
5.3.4.1 Clean the surface with a stream of clean potable
water, aimed at an oblique angle approximately ^ ft (0.6 m)
from the surface, having sufficient pressure to remove dust,
dirt, and loose material without damaging the substrate.
When necessary, hand scrub with a nonmetallic stiff-bristled
fiber brush.
5.3.4.2 Prior to water cleaning, make provisions for the
removal of wash water and contaminants generated.
5.3.4.3 If necessary, test the cleaned surface for moisture
content in accordance with Test Method D 4263 prior to
applying coatings.
5.3.5 Detergent Water Cleaning--Removes water-soluble
surface contaminants and oils, grease, and other emulsifiable
materials on the surface.
.
5.3.5.1 Scrape off heavy deposits of grease or oil and
prewet the surface with potable-water. Clean the surface with
a nonmetallic stiff-bristled fiber brush, using an aqueous
solution of detergent or nonsolvent emulsifier. Immediately
after treatment, before the surface dries, remove residues of
the cleaning agent by thoroughly flushing the surface with
clean potable water. Repeat flushing until the pH of the
surface water meets the acceptance criteria of Test Method
D 4262,
5.3.5.2 Repeat 5.3,5.1 until water does not bead on the
surfaces.

5.3.5.3 Prior to detergent water washing, make provisions
for the removal of wash water and cpntaminants generated.
5.3.5.4 If necessary, test the cleaned surface for moisture
content in accordance with Test Method D 4263.
5.3.6 Chemical Cleaning--This procedure is similar to
detergent water washing, but involves the use of proprietary
chemical cleaning compounds (generally hydrofluoric and
phosphoric acids) lor the removal'ofsurface deposits such as
soot, fly ash, and hydrocarbon residues.
N-.' --In some cases, removal of heavy soiling may require use
alkaline pretreatment prior to acidic cleaning.

to measuring containers at each leaching. When transferring cylinders, lift the cylinder out of the holding tank, allow sea water to drain off, install the cylinder into the rotating device, and submerge the painted area into the sea water. Immediately start rotation of the cylinder at 60 5 r/min, and continue rotation for 60 min. When transferring the cylinders, do not touch or in any way damage the paint Fdm, and dp not allow the paint surface to dry. The transfer should be completed as quickly as possible (generally, in less than 5 min).
9.9 If testing beyond the minimum (45 days) length requirement is desired, the study may he extended to 73 days.,,During the. extended test, remove the cylinders from the holding tank every 3 to 4 days to make a me,asurement of the leach-rate.
9.10 At the completion of the cylinder rotation, immedi ately remoye the cylinder from the measuring tank and return it to the holding tank. Pipet. a 25-mL subsample ofthe sea water into.a 50-mL centrifuge tube containing sufficient 10% HCi to reduce the pH to <4.0. If the number of samples from the leach measuring steps exceeds the daily analysis capacity, the samples may be refrigerated and stored in the acidified state.in a sealed container for up to 14 days. Clean the measuring containers using appropriate proce dures (distilled water or acid wash) before reuse.
9.11 Partition acidified sea water samples with 10 mL of toluene (1.5 min shaking on a mechanical shaker). Remove most of the toluene and wash it with 5 mL of a 3 % aqueous NaOH solution (10 min shaking). Pipet off (or separate using a separatory funnel) the organic phase and analyze for total tin content by GF-AAS. The toluene extract can be stored sealed in the dark at 4?C for up to 24 h before analysis.
10. Calculation
10.1 Calculate the concentration ofthe TBT cation in the sea water of the measuring container as follows:
CTBT = (C X- E x F)/S
where: CTBT = concentration of TBT cation (pg/L), C = concentration of tin in the toluene extraction
Oig/L), E = volume of toluene -- 10 mL, F = correction factor to convert tin to TBT = 2.5, and S' = aliquot of sea water analyzed = 25 mL. This equation can be simplified as follows if the prescribed volume of sea water and toluene are used:
tVoT = (Csn x 30 x 2.5)j25
= O'sn
10.2 Calculate the release rate by the following formula:
R = (C0' 0 x-Vx D)/(Tx A)
where: R = release rate (gg/cm2/day), D = 24 h/day, K = 1.5L, volume of sea water in measuring container, T = 1 h during which cylinder is in measuring container,
and A = 200 cm2 surface area of paint film. This formula can be simplified as follows:
DUP050298131
D 5108
R = (CTBT x 1.5 x 24)/(l X 200)
" ^*1' 1 x 0.18
10.3 Calculate the 14-day cumulative release of TBT cation as follows:
R = R, + (2 x R3) + (4 x R7) + (3 x Rl0) + (4 x i?I4)
where: R -- 14-day cumulative release, [xg/cm2 14 days, and /J,, J?3, R-!, Ri0, and i?i4 = release rates for sampling days 1, 3, 7, 10, and 14, respectively, jig/cm2 per day.
10.4 Calculate the average release rate (pg/cm2 per day) by averaging individual release rate measurements taken from day 21 through the last day of sampling (day 45 through day 73). If values at day 21 are high and it is suspected that the release had not reached pseudo steadystate conditions, then compare the release rate at day 21 to the mean for all release rates from day 21 through the termination of testing (45 to 73 days). If the release rate exceeds the mean by two or more standard deviations, then the release rate may be excluded from the average. If the day 21 release rate is excluded, the day 24 release rate may be
evaluated by the same procedure.
11. Report .11.1 Report the following information: 11.1.1 Report the concentration in micrograms per.L,
ofTBT cation in the sea water of the measuring tank and,t rate of TBT cation release (micrograms per square cei metre per day) for each sampling time (give values individual replicates as well as the mead). Plot the rate ! TBT release as a function of time (use linear axes), , report the 14-day cumulative release and the average rel< rate.

Protective coatings (paints) have been used extensively in the nuclear industry to protect the
surfaces of facilities and equipment from corrosion and contamination by radioactive nuclides in''
accordance with ALARA. In the absence of a standard method of selecting, testing, and evaluating
coatings, many sites evaluated paints by empirical tests to determine which were useful in their
particular operation. Understandably, the methods of testing were not uniform throughout the
industry. It has been very difficult, consequently, to compare the results obtained at one site with
those obtained at another. Standard tests whereby industrial (nuclear) users ofpaints systematically
prepare specimens and subject them to selected evaluations, thus permitting uniform comparisons,
are advantageous, internationally as well as domestically.
The designer of light water-moderated nuclear reactor systems must consider the possibility of a
Design Basis Accident (DBA) and the subsequent events which might lead to the release or
expulsion of a fraction of the fission-product inventory of the core to the reactor containment
facility. Engineered safety features, principally a reactor containment facility, are provided to
prevent the release of fission products to the biological environment during and after this
improbable event. The design, fabrication, quality assurance, and testing of these engineered' safety
features ensure reliable operation and safety under all anticipated conditions.
Large areas of the reactor-containment facility are painted with a protective coating. If severe
delamination, peeling, or flaking causes significant portions ofthe coating to be discharged into the
common water reservoir (primary containment sump), the performance ofthe safety systems could
be seriously compromised by the plugging of strainers, flow lines, pumps, spray nozzles, and core
coolant channels.
The safety requirement for protective coatings is to ensure that failure of the coatings under
DBA conditions does not adversely affect the performance of post-accident fluid systems.
Therefore, coatings must be qualified to the environmental exposures anticipated during normal
plant operation, and during DBA and other upset conditions.
This guide is the result of a comprehensive examination of the experience and data that have
been developed on protective coatings in the nuclear industry over approximately 40 years.
Standards pertaining to nuclear coatings have historically been covered by ANSI N5.12, N101.2,
and N101.4. Responsibility for updating, rewriting, and issuing appropriate ANSI replacement
standards has been transferred to ASTM, 'specifically ASTM Committee D-33, on Protective
Coating and Lining Work for Power Generation Facilities.
Quality assurance in the nuclear industry is a mandatory requirement for all aspects of safety
related nuclear coatings work. The objective of this guide is to provide a common basis on which
to define and specify the performance requirements for the coatings which will be used in Service
Level I and II areas of a nuclear facility. Proposed Regulation 10CFR50.65 (Draft Rule November
28, 1988) defines the requirements for an effective program for maintenance of nuclear power
plants. This guide may be used both for coatings applied to new nuclear power plants and to
facilitate implementation of the coating aspects of 10CFR50.65.
Scope mi 1.1 This guide provides a common basis on which protecjftive coatings for the surfaces of light water-moderated "Tfoclear power generating facilities may be qualified and

selected by reproducible evaluation tests. This standard also provides guidance for application and maintenance of pro
tective coatings. Under the environmental operating and accident conditions of nuclear power generation facilities, encompassing Pressurized Water Reactors (PWR's) and Boiling Water Reactors (BWR's), coating performance may be affected by exposure to any one, all, or a combination of the foEowing conditions: ionizing radiation; contamination by radioactive nuclides and subsequent decontamination

7. Sampling and Sample Preparation
7.1 Obtain the sample while the electrocoat bath is under proper circulation so a uniform sample is obtained. In the case of a ultrafiltrate sample, the material should be thor oughly mixed or stirred prior to drawing the sample, thereby ensuring uniformity.
7.2 After sampling, prior to removing the test specimen, it is mandatory the sample be shaken or stirred until it is homogeneous and free of any settled material. This is particularly important if there is a delay between sampling the bath and performing this test procedure. The absence of settled material should be ascertained visually or by inserting a spatula and scraping the bottom of the container. Continue to shake or stir the sample until specimens are taken for measurement. This Point is Very Important.
8. Procedure
MONVOLATILE CONTENT
8.1 Weigh two aluminum dishes separately, each to 0.1 mg and record as Wt.
8.2 Using a syringe, withdraw 1.0 to 1.5 of the well mixed sample, then quickly weigh the syringe to 0.1 mg, recording this weight as W2. Transfer the entire contents of the syringe into the aluminum dish. Reweigh the empty syringe to 0.1 mg and record as W3. In the case of ultrafiltrate clear liquids or of low solids paints, increase the specimen size to 5 mL and preheat at 60C for 2 h. Duplicate this step with the second aluminum dish (8.1).
8.3 Add a few millilitres of water to the specimen in the aluminum dishes prior to placing them in the oven. This facilitates uniform spreading of the material. Place the dishes in the 110"C oven for 1 h.
8.4 Remove the dishes from the oven and allow to cool to room temperature in a dessicator. Reweigh them to 0.1 mg and record the weights as WA.
8.5 Retain the dishes for measurement of inorganic pig ment content as detailed in a following section of these test methods.
961
DU P05 02 98141
9. Calculation
9.1 Calculate the percent nonvolatile content as follows:
, NV = WA- W,`x 100 w2-w3
where: W- = weight of empty aluminum dish, g, W2 = weight of syringe filled with sample, g, fV3 = weight of empty syringe, g, and W4 = weight of dish and contents after I h at 110C, g.
10. Precision and Bias
10.1 Precision is based on an interlaboratory study in which the operators in each of ten laboratories analyzed in duplicate on 2 days, four different electrocoat-bath samples with nonvolatile contents ranging from 0.30 to 25.2 % The results were analyzed statistically in accordance with Practice E 180. The interlaboratory coefficient of variance was 1.6 % at 30 df and the interlaboratory coefficient of variation was 2.3 % at 21 df. Based on the these coefficients, the following criteria should be used forjudging the acceptability of results at the 95 % confidence level:
10.1.1 Repeatability: Two results, each the mean of dupli cate determinations obtained by the same operator on different days, should be considered suspect if they differ by more than 4.6 % relative.
10.1.2 Reproducibility: Two results, each the mean of duplicate determinations obtained by operators in different laboratories, should be considered suspect if they differ by more than 6.7 % relative.
10.2 No bias has been determined for this test method.
11. Procedure
INORGANIC PIGMENT CONTENT
11.1 Place the weighing dishes used for the nonvolatile content determination in the muffle furnace at 500C for 2 h.
11.2 After 2 h, remove the dishes from the muffle furnace, transfer them to a dessicator and allow to cool to room temperature. After cooling, remove dishes and weigh to 0.1 mg, recording these weights at Ws.
N;<' 1--If an organic char is still present in the aluminum dish aii' -

13. Precision and Bias
13.1 Precision estimates are based on ah interiaboratorv study in which the operators in ten different laboratories ' analyzed in duplicate on 2 days, four electrocoat bath materials containing inorganic pigment content ranging from 0.17 to 4.52 weight %. The results were anahzej statistically in accordance with Practice E 180. The intralaboratory coefficient of variation was 2.2 % relative at 40 df and the interlaboratory coefficient of variation wj, 10.8 % at 36 df. Based on these coefficients, the followine criteria should be used forjudging the acceptability of result at the 95 % confidence level:

4. Conditions Affecting Solvent-Reducible Coatings
4.1 Substrate Type--The substrate to be painted . n affect not only the application properties of a coating, such as gloss and uniformity, but is also a factor in determining '.I >. type ofcoating to use. For instance, low-gloss wall finishes do not have the abrasion resistance required on floors, -whereas finishes intended only for interior service probably do not have adequate resistance to weather factors. Other, factors are the type and quality oFwood or wood composite (plywood, particle board or hardboard), the type, quality and alkaline of concrete, plaster and joint cement systems, and the type and condition of any previous coatings.
4.2 Substrate Conditions--Conditions such as porosity, hardness or, in the case of unpainted concrete, alkalinity determine the kind of coating that can be applied. The condition of previously painted substrates, such as degree of chalk, presence of grease, dirt, and mold, film adhesion and porosity, and the general condition of the previous coating, all influence the performance of coatings. Smoothness of the substrate affects the spreading rate, final appearance, and texture.

humidity at the time of coating application and during drying.
4.7 Environmental conditions after application, both gen eral for the area and specific, such as under eaves, behind shrubbery, northside and southside exposure.5
5. Selection of Tests
5.1 Because the conditions to which a coating is subjected vary with (a) the surface type: wall, floor, ceiling, and {b) the
service environment: exterior or interior, specialized types ol solvent-borne coatings have been developed for the different locations. The recommended test methods presented i'r Tables 1 and 2 cover practically all the properties ol solvent-reducible coatings but all of them are not required
with each type. Coatings intended for exterior use only 01 both exterior and interior use require certain properties not relevant to those for interior use only. Selection of the methods to be followed must be governed by experience and the requirements in each individual case, together with agreement between the purchaser and the seller.
5.2 The purchaser should first determine the properties a coating should have and then select only those test methods

neasure or evaluate those properties. After selecting the l tests, the purchaser should then decide which propare the most important and establish the requirements deifications accordingly. Since coating properties frepy tend to oppose each other, such as low sheen versus Ifcleansability, some properties may need to be less iasized if others are to be accentuated. This balance of ties must be considered when selecting the tests and {fishing the requirements. The significance of the tests he normal range of values are presented in the different |tas, in most cases. This guide does not indicate relative importance ofthe ps tests nor does it recommend specific test values use properties very important to one purchaser may be i to another.
|mpling
Prior to sampling, the condition of the container I'd be checked since damage to it may cause evaporation, png, or other undesirable effects on the coating.
Sample in accordance with Practice D 3925. Deterthe density in pounds per gallon (kilograms/litre)' in ifdance with Test Method D 1475. Continue sampling determining density until successive results agree within i (45 g) or as agreed upon between the purchaser and , Then take samples for testing. Specify the amount requited for a representative ble, the package sizes, and an identification- code. A {gS. gal (or 4-L) sample is usually sufficient for the amended tests, but for guidance in selecting a sampling |consult Practice E 105.
liquid Coating-Properties
R Skinning--Coatings that contain a binder that dries Sedation may be subject to skin formation in a partially-
1 can: Since skins are insoluble in the material they must jjemoved before use. The referenced test in a partially-
container indicates the tendency of the material to a. A typical minimum time for skinning in accordance V this method is 48 h. Examine the original sample for |s, both on and below the' surface. Using a well-mixdd glftee portion of the sample, perform a skinning test in Jfdance wtih Guide D 154. II Condition in Container--Thickening, settling, and aration are undesirable and objectionable if material that (been stored cannot be readily reconditioned and made able for application with a reasonable amount of stirring. ' referenced method covers procedures for determining nges in properties after storage and lists characteristics
are undesirable and objectionable in a stored paint, iermine condition in the container in accordance with Shod 3011 of Federal Test Method Standard No, 141`. Sse also 7.13, Package Stability.) '.3 Coarse Particles and Foreign Matter--Liquid coatings gst be free of coarse particles and foreign matter to be able jjbnn uniform films of good appearance, a typical max im being 0.5 weight % of the total material. The srenced method with a 325-mesh (45-um) screen gives the jjpent of these, particles. Determine content of coarse Seles and foreign matter in accordance with Test Ihods D 185.
7.4 Density or Weight per Gallon--The density measured in pounds per gallon (kilograms per litre = g/mL) is used to
ensure product uniformity from batch to batch, provides a check agaihst the theoretical weight calculated from the
formula, and is useful for determining the similarity of two samples. The referenced method gives a procedure for
measuring the density of the coating at a specified tempera ture. Most interior paints have densities of about 10 to 12 Ib/gal (1.2 to 1.4 kg/L). Determine density in, accordance with Test Method D 1475, using a calibrated weight per gallon cup.
7.5 Fineness ofDispersion--Generally, the more finely a pigment is dispersed, the more efficiently it is being utilized. One method for measuring the degree of dispersion (com monly referred to as "fineness of grind") is-to drdw the liquid coating down a calibrated tapered groove varying in depth from 4 to 0 mils (100 to 0 jxm) (0-8 Hegman units). The
depth at which continuous groupings ofparticles or agglom erates, or both, protrude through the surface of the wet film is taken as the fineness of dispersion value: Higher readings in Hegman units or lower readings in mils or micrometres indicate finer dispersion. Low sheen finishes may have a dispersion value of.2 mils (50 pm or 4 Hegman) while gloss enamels might be neax zero (8 Hegman) indicating that the pigment agglomerates are too small to Be detected by the referenced method. Determine fineness of dispersion in
accordance with Test Method D 1210. 7.6 Consistency (Low-Shear Viscosity)--Consistency is
important, relating to application and flow, and should fall within a' stated range for satisfactory reproduction of a specific formula. While consistency is an important property it does not determine the quality of a coating and should be used mainly to ensure product uniformity. In the referenced method, consistency is defined as the load in grams to produce a specified rate of shear. The load.value is frequently converted to Krebs units (KU) and the Stormer Consistency reported on that basis. Although the consistency of most solvent-borne house and trim coatings is about 150 to 3Q0 g/100 revolutions (72 to 95 KU), a much wider range is possible because of the great variation that may occur in the rheological properties of these, paints. Enamels for profes
sional painters are usually formulated at a higher consistency range than consumer enamels. Typical ranges are_75 to 90 KU Fox consumer enamels and 90 to 100 for professional painter'enamels. Two paints of the same consistency may have quite different rheological properties during applica tion. Determine the consistency in accordance with Test Method D 562. : 7.7 Rheological Properties ofNan-Newtonian Materials-- Rheological properties are related to application and flow characteristics of the liquid coating. The referenced methods cover the determination of rheological properties and are particularly suited for coatings that display thixotropic char acteristics. They actually measure viscosity under different shear rates. In Test Method D 4287 the rate is similar to that occurring during brush application so that the measured viscosity is related to brush drag, spreading rate and film build. Determine rheological properties in accordance with Test Methods D 2196 or D 4287, or both.
7.8 Flash Point--Organic solvents used in these coalings have characteristic temperatures at which they support
DUP050298147
ii
combustion. This temperature is known as the flash point and is often used for danger classification in shipping by common carrier. It is also used to determine conditions of storage to meet fire regulations and the safety requirements of the U.S. Occupational Safety and Health Act (OSHA). Determine flash point in accordance with Test Methods D 93, Part B, or D 3278.
7.9 Odor--Some solvent combinations produce obnox ious odors, particularly when painting indoors with inade quate ventilation and at elevated temperatures. Interior solvent-borne coatings usually contain low-odor or odorless mineral spirits. Nevertheless they should be evaluated to ensure that they are acceptable. Test for odor in accordance with Method 4401 of Federal Test Method Standard No. 141. Although not specifically designed for liquid coatings Test Method D 1296 may be used with the solvent-reducible type.
7.10 Absorption--On porous surfaces, binder penetration can result in pigment volume concentration changes as the film dries. This may cause appearance to vary. The refer enced method provides a rough measure of the wetting and penetrating properties of the binder on a porous surface. Determine the absorption in accordance with Method 4421 of Federal Test Method Standard No. 141.
7.11 Colorant Acceptance--Tintability ofwhite bases with colorants of standardized tinting strength is a trade require ment. If tinting colors are not adequately compatible with tint bases, lighter, darker, or nonuniform shades ofcolors are produced. There is no accepted ASTM test method at present. Test methods may be agreed upon between the purchaser and seller.
7.12 Dilution Stability--Dilution with a specified thinner shows whether the materials are compatible and whether the reduced coating is stable. Consequently the suggested diluent should be readily incorporated into the coating without excessive stirring or shaking. The referenced method evalu ates the stability of the' material that has been reduced by a giveh amount or to a specified viscosity. Determine dilution stability in accordance with Method 4203 of Federal Test Method Standard No. 141.
7.13 Package Stability--Since paints cannot normally be used immediately after manufacture, they must remain stable in the can for some time. At normal temperatures most paints can be stored'for over a year with little change in properties. Although indications of long term package sta bility can usually be obtained in several days or weeks'at an elevated temperature, such as 122F (50C) or 140F (60"C), occasionally the results of the accelerated test do not agree with those at prolonged normal storage conditions. The referenced method predicts the change in consistency and certain other properties of packaged paint when stored at temperatures above freezing. Determine package stability in accordance with Test Method D 1849.
8. Coating Application and Film Formation
8.1 Application Properties--Application or working prop erties of a paint are generally compared to a standard or described by requirements in the product specification. Determine working properties in accordance with Method 454! of Federal Test Method Standard No. 141.
8.1.1 Brush Application--Brushed films should be smooth and free of seeds and on vertical surfaces should
I
show no sagging, color streaking, or excessive brush mark^ff Brush drag should not be excessive although some degrefr'Jii drag may be desirable for adequate film thickness appi^;^*
tion. Wall finishes are tested on vertical surfaces and enamels on horizontal surfaces, although evaluation of th/'sl latter on vertical surfaces may be necessary to determine^*'* performance on stair risers, railings, posts, etc. The refer. \ enced method covers a means for the determination oi i)5tr" brushing properties of a coating. Even though the tes: ^
subjective someone experienced in the art can produce quite consistent results, particularly in the evaluation of drai "'.i
qualities. Determine the brushing properties in accordance with Method 2141 of Federal Test Method Standard \o 141.
8.1.2 Roller Application--Both wall and floor coating- Jrc frequently applied by roller. This type of application tends to produce some stipple pattern. The referenced method covers the evaluation ofa material's characteristics when applied > > roller. Determine roller coating properties in accordance with Method 2112 of Federal Test Method Standard No, 141.
8.1.2.1 Some coatings spatter more than others when applied by roller. The degree to which a paint spatters when roller applied can be determined by the density ofthe spauer. In the referenced method a specially designed notched sped is rolled through a film of the test material that has been applied to a plastic panel. Any spatter generated fells upon i catch paper and after drying is rated against photographic standards. This procedure eliminates the influence of the, roller cover, thus determining the spattering characteristic of the paint alone. Determine spatter resistance in accord ance with Test Method D 4707.
8.1.3 Spray Application--Architectural coatings are sometimes applied by spray. Both air and airless .spray are used on commercial work. Determine the spray application properties in accordance with Method 2131 of Federal 'Usi
Method Standard No. 141. Manual application is very, subjective and should be performed only by an individual skilled in the art of using spray equipment.
8.2 Drying Properties--The drying time of a coating is important in determining when a freshly painted room, floor or stair may be put back in use. Slow drying may result in dirt or insect pickup resulting in a poor appearance or, ii -t an exterior surface, rain or dew may cause a nonuniform appearance. The drying time ofa coating is determined by us composition and by atmospheric conditions during drying. Typical drying times for enamels are 'A to 2 h set-to-touch and 18 h dry hard under normal temperature and humidity conditions. Some coatings lose drying speed during storage in the container. Any of the several methods for determining the various stages of film formation in the drying or curing of organic coatings may be used. For example, if two coats are specified the determination of "dry-to-recoat" time is impor tant. Determine appropriate drying timefs) in accordance
with Test Methods D 1640. 8.3 Levelling Properties--Levelling is an important prop
erty when smooth, uniform surfaces are to be produced, as it affects hiding and appearance. The referenced method covers the relative levelling characteristics of liquid coatings. Deter mine levelling in accordance with Test Method D 4062.
8.4 Sag Resistance--Some coatings sag and form curtains

Iculate in accordance with Test Method D 2244 the color Terences that have been measured instrumentally. 9.3 Directional Reflectance--This property is a measure if the appearance of lightness of a coating. It is usually Ssigned a value in specifications for white and pastel shades, Etypicai minimum, reflectance value being 86 % for white iall paint. In the referenced method the directions of fumination and viewing are specified so as to eliminate the feet of gloss. Determine daylight directional reflectance in Pgcordance with Test Method E 97. 9.4 Gloss--This property is a measure of the capability, of , coating surface to reflect light in a mirror-like (specular) tanner, that is, light strikes the surface and is reflected at the Iqual but opposite angle. In the referenced method the Numerical gloss units are the ratio of light reflected by a specimen to that reflected by the primary standard black
lass that is assigned a gloss value of 100. The gloss of some
t prop
floatings varies greatly with the angle of incidence so that a
el, as it

covers
tents over a wide range of angle. In practice, the gloss of
Deter-
rchitectural finishes is adequately characterized by measure-

tents at 60 or 85, or both, from a line perpendicular formal) to the surface. The 85 angle is a very low
("grazing") angle (5) of illuminating and viewing the surface and the gloss at this angle is called "sheen". Attempts to standardize the levels of gloss associated with the several descriptive terms have not been very successful since the gloss scale is. continuous with no distinct boundaries. Hence, there is some overlap at the ends of some gloss classifications in common usage.
9.4.1 Gloss, 60--Semigloss enamels are particularly sen sitive to enamel hold-out of primers and undercoats. Low or uneven gloss readings are indicative of this defect. Oil house paints are typically in a 60gloss range from 30 to 70 while trim enamels are from 70 to 90. Floor enamels generally have a high (90+) gloss reading when first applied but this decreases- with time and traffic. Interior senaigloss enamels after drying 48 h are typically in the range from 40 to 70 but measurements taken shortly after drying should be repeated after one week because the gloss can drop considerably in the first few.days of drying. Determine the 60 gloss in accord ance with Test Method D 523.
9.4.2 Sheen (85 Gloss)--Although low-gloss paints with good uniformity ofappearance at low angles of viewingoften have little sheen while those with good cleansability usually have moderate sheen, this is not always the case so that sheen should not be used as a measure of other paint properties. Most flat wall paints have a sheen of about 1 to 10. The referenced method, using the 85 geometry, is useful in characterizing the low-angle appearance of low-gloss coat ings. Determine the sheen (85gloss) in accordance with Test Method D 523.
N>?' 3--This property is of particular interest with flat to low-gloss
finishes.
9.5 Hiding Power--Hiding power is a measure of the ability of a coating to obscure the substrate and is usually expressed as tshe spreading rate for a specified-- level of opacity. It is, however, dependent on uniformity of film thickness, which in practical applications is influenced by flow, levelling and application properties of the coating.-,Test Method D 2805 is precise and gives an absolute rather than a comparative result. Paint is applied with an applicator bar to minimize the effects of flow and levelling, film thickness is rigorously measured, and film opacity is determined instru mentally, Test Method D 344 is a practical test in which paint is applied with a brush, wet-film thickness is approxi mately controlled by spreading rate, and hiding power is evaluated visually by comparison with a standard paint, but resu.lts are affected by flow and levelling of the materials. Determine hiding power in accordance with Test Methods D 344 or PJ2805.
9.6 Yellowness Index--The referenced method is used for white or near white specimens to determine color departure from white toward yellow when first applied. Determine the yellowness index in accordance with Method E 313. (See also 10.2.1.)
10. Properties of the Dry Film
10.1 Interior and Exterior Coatings: 10.1.1 Abrasion Resistance--Abrasion resistance is a measure of the ability of a dried film to withstand wear from foot traffic and marring from objects rolled or pulled across
D 5146
the surface. In the referenced methods, dry abrasive is applied to a coated panel using the force of gravity or a jet blast for free-flowing abrasive or a weighted wheel for abrasive embedded in a resilient rubber matrix. Determine dry abrasion resistance in accordance with Test Methods D 658, D 968 or D 4060. (See 10.2.2.1 for wet abrasion resistance.)
N@A' 4--Because of the poor reproducibility of abrasion test
methods, testing should be restricted to only one laboratory when numerical abrasion resistance values are to be used. Interiaboratory agreement is improved significantly when rankings are used in place of numerical values.
10.1.2 Adhesion--Adhesion is the property of a film that resists removal from the substrate. It is an important property in a paint. Determine adhesion in accordance with Test Method D 2197 or D 3359, or both.
10.1.3 Flexibility--Elongation is a measure of the flexi bility of a coating film. Generally, gloss house paints and trim enamels have no problems in passing a mandrel bend test at '/s in. (3.2 mm). However, interior flat and eggshell finishes may pass only a '/2-in. (12.7-mm) bend. For exterior coatings Test Method D 2370 is a much more discriminating method.11 Determine flexibility in accordance with Methods D 522 or elongation with D 2370.
10.2 Interior Finishes: 10.2.1 Color Change of White Architectural Enamels-- Color permanence is an important characteristic for interior white enamels. Lack of permanence is usually caused by after-yellowing. The referenced method attempts to accel erate color change by exposing coatings to dry sulfur dioxide. Determine resistance to color change in accordance Test Method D 1543. 10.2.2 Washability and Cleansability--The capability of satisfactorily removing marks without damaging the film is essential for good performance of interior finishes. A coating may be washable, that is, unaffected by the detergent solution, but may not have good cleansability. Frequently the difference between the two terms "cleansability" and "washability", is not clearly understood so that there is confusion as to what is really being tested; for example, the title of Test Method D 3450. Cleansabifity is evaluated by applying one or more stains and soils and determining how readily they are removed. Washability is evaluated by determining the resistance of the film to wet erosion either by visual assessment or measured film loss. In general, the precision of both types of test is poor because several properties, such as hardness, water and detergent resistance, cohesion and adhesion, are involved and the end point, except for the wet abrasion method, is rather indefinite. 10.2.2.1 Washability (Also referred to as Scrubbing or Wet Abrasion Resistance)--The scrubbing method, Test Method D 2486, developed for interior latex flat wall paints can be applied to coatings of almost any type. In it the coating is applied to a black plastic panel that, during scrubbing with a nylon brush and abrasive cleaning agent, is raised by a narrow shim to concentrate the test area. The number of back-and-forth strokes (cycles) required to remove the film over the shim is determined. The wet-abrasion method, Test
u H. E. Ashton, Journal ofCoatings Technology> Vol 51, June 1979, p. 41.
Method D4213, is similar except that a sponge is used irf'
place of the bristle brush while the shim is not used. Thi|T
method also provides for the use of a nonabrasive medium
with paints having very low abrasion resistance. The weight
or volume loss per 100 cycles to erode the film almost to
exposure of the black substrate is the measure of scrub'-1
resistance. Evaluate washability, as described just, in accord- ?
ance with Test Methods D 2486 or D 4213.
10.2.2.2 Cleansability--The older referenced methrd.
Test Method D 3450, is similar to the wet-abrasion method^
Test Method D4213, except that the sponge is used with'
either the nonabrasive or abrasive cleaning agent to remove a-
carbon black-oil stain. The ability to remote the stain i&,
expressed as the ratio (in percent relative) of the reflectance
of the cleaned area to that of the area before application of
the stain. In Test Method D 4828, referred to as a "practii nl '
test, numerous staining and soiling agents found in service
and commercial abrasive or nonabrasive cleaners as well as
the standardized cleaning agents can be used. In the current ,
edition the films, are cleansed only manually with the result
that the method is not suitable for interlaboratory testing.
Evaluate ease of removability in accordance with Tes:
Methods D 3450 or D 4828.
10.2.3 Resistance to Household Chemicals--An impor
tant property of interior coatings is the ability to resist
spotting, softening or removal when subjected to household chemicals or strong cleaners. Determine resistance to these chemicals in accordance with Test Method D 1308.

10.3 Exterior Coalings:

10.3.1 Blister Resistance--Blister resistance is the ability 1
of a dry film on wood to resist the formation of blisters''
caused by water from the wood substrate. In practice water.,
can come from either the interior of a home or fron
structural defects that permit entry of exterior water behind'
the wood. Moisture blister resistance can be qualitatively
evaluated in a laboratory test. Determine resistance to
moisture blistering in accordance with Practice D 4585.
10.3.2 Exposure Resistance--Ifthe coating is intended for
exterior use, evaluation of the resistance to weathering maj
be required. In conducting exterior exposures follow Practice
D 1006 for wood substrates or Test Method D 1014 for steel.
10.3.2.1 In establishing exterior performance on wood,
use the panels described iiTSpecification D 358.
10.3.2.2 Degree of Chalking--Determine the rating using
Methods D 659 or D 4214.
10.3.2.3 Degree of Checking--Determine the rating using
Test Method D 660.
10.3.2.4 Degree ofCracking--Determine the rating using
Test Method D 661.
10.3.2.5 Degree of Erosion--Determine the rating using-
Test Method D 662.
10.3.2.6 Degree of Flaking--Determine the rating using
Test Method D 772.
10.3.3 Mildew Resistance--Virtually all exterior paints
are subject to microbiological discoloration on the surface
with time. This is especially true in warm, moist climates.
Determine mildew resistance in accordance with Practice
D 3456.
10.3.4 Fume Resistance--Some paints exhibit a change in
appearance (usually color) when exposed to air containing
certain sulfur compounds, notably hydrogen sulfide and

lioxide. This type of atmosphere may be present near rial or other polluted areas and can cause paint to <or darken in as little time as overnight. There are no
or Federal test methods for evaluating this color I, but one procedure used by the industry is as follows: |:4.1 Apply a sufficient number of coats of the paint to kss plates to hide the surface completely, allow to dry
and expose one in a moist atmosphere of hydrogen I for 18 h. Compare the color with the unexposed plate, itposed plate should be practically no darker than the |osed one. The color difference should not exceed that eh plates that have been coated with a paint made with
dioxide pigment, lead-free zinc oxide, raw or linseed oil, and sufficient cobalt added for drying, nilarly treated.
jjfhating Analysis
jf! Coating Analysis--If a specification requires certain jgiaterials or certain components in a given amount then Sis is needed to determine whether the specified com-
hts are present and in what. amounts. Analysis is arily a measure of uniformity and does not necessarily |ish quality that can also be greatly affected by manu ring techniques. No single schematic analysis is compreve enough to cover the wide variety of paint composi-
f Select test procedures from Methods D 215 and other methods that are pertinent to the components of
Bnt-bome coatings. |!2 Volatile Content--The per cent of volatile matter is a jgure ofthe amount of a film lost as it dries. This quantity
{ necessarily indicative of the quality of the coating. It is
however, for determining the similarity of two |es. The referenced method covers the determination of blatile content of solvent- and water-reducible coatings. Quantity determined subtracted from 100 % gives the |piatile content of the coating. Determine the volatile ent in accordance with Test Method D 2369. Of, [s3 Nonvolatile Content (Volume Percent)--The nonvolay' : content by volume is a useful figure in calculating a* age or spreading capacity per gallon (or litre) at a d |fied dry-film thickness. Determine nonvolatile content line percent in accordance with Test Method D 2697.
11.4 Water Content--If too much water is incorporated in a solvent-reducible coating it may retard the drying at high relative humidities. The amount of water in a coating is required in the calculation of the volatile organic content (VOC) of coatings. One referenced method covers the determination of water in paint and related materials by distilling with a volatile solvent. The newer method utilizes the Karl Fischer reaction. Determine water in accordance with Test Methods D 1208 or D 4017.
11.5 Pigment Content--Pigment provides the hiding and color and influences many other properties of a coating. The referenced method describes the procedure for the quantita tive separation of the vehicle from the pigment in solventreducible coatings. It is used to measure the weight percent pigment in the paint. Determine the percent pigment con tent in accordance with Test Method D 2371.
11.6 Pigment Analysis--The analysis of pigment may be required if the product is covered by a specification or upon agreement between the purchaser and seller. Analyze the pigment in accordance with selected test procedures from Methods D 215 and other appropriate ASTM methods.
11.7 Nonvolatile Vehicle Content--The nonvolatile ve hicle is the film-forming portion of a coating excluding the pigment. Water, volatile thinner, and pigment are deter mined and their sum subtracted from 100 % to give the binder content in accordance with Methods D215. The vehicle may be separated for further analysis.
11.8 Separation of Vehicle--The recommended proce dure describes this separation for certain solvent-borne coatings. If desired or required, separate the vehicle in accordance with Method D 2372.
11.9 Identification of Nonvolatile Vehicle--The type of. binder used in a coating has a great influence on its properties. The referenced method covers the qualitative characterization or identification by infra-red spectroscopy of separated nonvolatile vehicle. It is useful in detecting uniformity, batch to batch, and the presence of adulterants. Identify the nonvolatile vehicle in accordance with Method D2621. The composition of this vehicle can be further broken down into the types of oils present. If desired determine the identity of oils in accordance with Method D 2245.

(19-nvm) wide and are not normally considered a part of the
test area.
"
XL 1.6 Unnumbered Stripes--The unnumbered stripes
shown ip Figure 1 are an integral part ofthe test area; Their
purpose is to favor application uniformity on the numbered
stripes by preempting the boundary locations that tend to be
less uniformly coated than more centrally located areas.
X1.1.7 Grey Stripe Reflectances5--The reflectance values
of the numbered stripes are selected with the objective that
their color differences with respect to the white surround'.will
be in the geometric sequence: 2,4, 8,16,32, and 64 CIELAB
units. The defining variable for the grey stripes is not the
reflectance as such, but the ratio of the grey reflectance G to the white reflectance W. Table XI. 1 shows the relevant relationships and production tolerances.
NBD' Xl.l--The term "reflectance" as used here refers to the
luminous reflectance factor as defined in 4.2 of Method E 97, which ` may be expressed as a decimal fraction or as a percentage. The latter is numerically the same as the CIE Y-tristimulus value and is the scale reading on most if not all commercial colorimeters.

Standard Practice for
Discontinuity (Holiday) Testing of Nonconductive Protective Coating on Metallic Substrates1 2
This standard is issued under the fixed designation D 5162; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year oflast reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or ieapprcival.
1. Scope
1.1 This practice covers procedures for determining discontinuities using two types of test equipment:
i. 1.1 Test Method A--Low Voltage Wet Sponge, and 1.1.2 Test Method B--High Voltage Spark Testers. 1.2 This practice addresses metallic substrates. For con crete surfaces, refer to Practice D 4787.3 1:3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appro priate safety and health practices and determine the applica bility ofregulatory limitations prior to use.

2.1 ASTM Standards: D4787 Practice for Continuity Verification of Liquid or
Sheet Linings Applied to Concrete Substrates3
3. Terminology
3.1 Description of Terms Specific to This Standard: 3.1.1 discontinuity, as used in this standard--a void, crack, thin spot, foreign inclusion, or contamination in the coating film that significantly lowers the dielectric strength of the coating film. May also be identified as a holiday or pinhole. 3.1.2 holiday, as used in this standard--a term that identifies a discontinuity. 3.1.3 holiday detector, as used in this standard--a device that locates discontinuities in a nonconductive coating film applied to a conductive surface. 3.1.4 pinhole, as used in this standard--a film defect characterized by small porelike flaws in the coating which, when extended entirely through the film, will appear as a discontinuity. A pinhole in the finish coat may not appear as a discontinuity.
4. Significance and Use
4.1 A coating is applied to a metallic substrate to prevent corrosion, reduce abrasion or reduce product contamination, or both. The degree of coating continuity required is dictated by service conditions. Discontinuities in a coating are frequently very minute and not readily visible. This practice provides a procedure for electrical detection of minute

discontinuities in nonconductive coating systems.
4.2 Electrical testing to determine the presence aiul
number ofdiscontinuities in a coating film is performed on j
nonconductive coating applied to a conductive surface. TLe
allowable number of discontinuities should be determined '
prior to conducting this test since the acceptable quantiiy of ^
discontinuities will vary depending on coating film thickness, j
design, and service conditions.

4.3 The loft voltage wet sponge test equipment is genet- .1
ally used for determining the existence of discontinuities in I
Jcoating films having a total thickness of 20 mils (0.5 mm) or t
less. High voltage spark test equipment is generally used for
determining the existences of discontinuities in coating films Jg
having a total thickness of greater than 20 mils (0.5 mm) *
4.4 Coatings that are applied at a thickness of less than 20 j
mils (0.5 mm) may be susceptible to damage if tested with i
high voltage spark testing equipment. Consult the coatine 1
manufacturer for proper test equipment and inspectur
voltages.
^
4.5 To prevent damage to a coating film when using higjjrf)
voltage test instrumentation, total film thickness and dielecrifS
trie strength in a coating system shall be considered m,fl|
selecting the appropriate voltage for detection af.J
discontinuities. Atmospheric conditions shall also be consid- M
ered since the voltage required for the spark to gap a given %
distance in air varies with the conductivity of the air at the *
time the test is conducted. Suggested starting voltages are j
provided in Table 1.

Procedure
isting [5,2.1 Sufficient drying or curing of the coating shall be lowed prior to conducting a test. The length of time
stion, V fi Suited shall be obtained from the coating manufacturer. llvents retained in the coating film could produce erro-
Ipus indicators. 15.2.2 The surface shall be clean, dry, and free, of oil, dirt lid other contaminates. Measure the film thickness of the gating with a nondestructive dry film thickness gage. If the |ating film exceeds 20 mils (0.5 mm), use the. procedures
high voltage spark testing described in Test Method B, fgh Voltage Spark Testing. |5.2.3 Test the instrument for sensitivity in accordance |th 5.3.
5.2.4 Attach the ground wire from the instrument ground output terminal to the metallic substrate and ensure positive electrical contact.
5.2.5 Attach the exploring sponge lead to the other output terminal.
5.2.6 Wet the sponge with a solution consisting of tap water and a low sudsing wetting agent, combined at a ratio of not more than xh fluid oz of wetting agent to 1 gal water. An example of a low sudsing wetting agent is one used in photographic development. The sponge shall be wetted sufficiently to barely avoid dripping of the solution while the sponge is moved over the coating. The wetting agent residue must be removed prior to executing repairs. n
5.2.7 Sodium chloride (salt) shall not be added to the wetting solution because of the potential erroneous indica tions of discontinuities. The salt, after drying on the coated surface, may form a continuous path of conductivity. It will also interfere with intercoat adhesion of additional coats.
5.2.8 Contact a bare spot on the conductive substrate with the wetted sponge to verify that the instrument is properly grounded. This procedure shall be repeated periodically during the test.
5.2.9 Move the sponge over the surface of the coating at a moderate rate approximately I ft/s (0.3 m/s), using a double pass over each area. Apply sufficient pressure to maintain a wet surface. Ifa discontinuity is detected, turn the sponge on end to determine the exact location of the discontinuity.
5.2.10 Discontinuities that require repair shall be identi fied with a marker that is compatible with the repair coating or one that is easily removed.
5.2.11 To prevent telegraphing (current traveling through a moisture path to a discontinuity, giving an erroneous indication), take care to ensure that the solution is wiped dry from a previously detected discontinuity before continuing the test.
5.2.12 The wetting agent must be completely removed by rinsing the holiday area prior to repair.
5.2.13 Wet sponge holiday detection is not recommended between coats of a multicoat system. However; when a test is conducted between coats of a multicoat system, a wetting ageht shall not be used and all residue left by the test water must be completely removed prior to applying additional coats.
5.3. Verifying Operation of Equipment
5.3.1 The instrument shall be tested for sensitivity prior to initial use and periodically thereafter, in accordance with the equipment manufacturer's instructions.
5.3.2 Test the battery for proper voltage output. Refer to the manufacturer's instructions.
5.3.3 Switch the instrument to the "on position," if applicable.
5.3.4 Wet the sponge with a wetting solution consisting of tap water and a wetting agent (see 5.2.6).
5.3.5 Connect the ground cable to the instrument ground output terminal.
5.3.6 Touch the ground cable alligator clip to the wetted sponge. The instrument signal should actuate in accordance with the instrument manufacturer's instructions.
5.3.7 If the instrument should fail to signal, it shall be considered defective.

5.4 Verifying Instrument Calibration
5.4.1 Verify instrument calibration in accordance with the manufacturer's latest published instructions. If out of cali bration, the instrument shall be calibrated in accordance with the instrument manufacturer's latest published instruc tions, or returned for calibration.
TEST METHOD B--HIGH VOLTAGE SPARK TESTING
5.5 Apparatus
5.5.1 High Voltage Detector (in excess of 800 V)--An electronic device used to locate discontinuities in a nonconductive protective coating applied to a conductive substrate. It consists of an electrical energy source, an exploring electrode, and a ground wire connection from the indicator signaling current flow through a coating filih discontinuity to'the substrate. The defector shall be equipped with a visual1 or audible indicator, or both.
5.5.2 Exploring Electrode, shall be of the type capable of maintaining continuous contact with the surface being inspected, such as bolts, raised areas, etc. It shall be kept clean and free of coating material.
5.5.3 High Voltage Electrical Detector, can be identified as either a pulse or direct current type. A pulse type detector discharges a cycling, high voltage pulse, while a direct current type discharges continuous voltage.
5.6 Procedure
5.6.1 Sufficient drying or curing of the coating shall be allowed prior to conducting a holiday test, The length of time required shall be obtained from the coating manufac turer. Solvents retained in the coating film could produce erroneous results, as well as a fire hazard.
5.6.2 The surface shall be clean, dry, and free of oil, dirt and other contaminates. Measure thickness of, the coating with a nondestructive dry film thickness gage. If the coating film is less than 20 mils (0.5 mm), consider using procedures for low voltage testing (see Test Method A, Low Voltage Wet Sponge Testing). Although the high voltage spark tester is suitable for determining discontinuities in coating films of less than 20 mils (0.5 mm), it is recommended that the coating manufacturer be consulted before using this test. Certain coatings may be damaged if tested with this equip ment.
5.6.3 Verify test instrument operation in accordance with 5.7.
5.6.4 Adjust the test instrument to the proper voltage for the coating thickness being tested. In selecting the inspection voltage, it is important to provide sufficient voltage to break the air gap that exists at the holiday. The air gap will vary depending on the total applied film thickness. The voltage required to break a given air gap may also vary due to atmospheric conditions such as relative humidity. Ensure that the voltage is high enough to break the air gap equivalent to the highest coating film thickness by separating the exploring electrode from the bare metal substrate using a nonconductive spacer equal to the maximum coating thick ness. The voltage is set high enough to conduct the holiday test only if the spark will jump the gap formed by the spacer. Excessive voltage may produce a holiday in the coating film. The maximum voltage for the applied coating shall be
obtained from the coating manufacturer. Table 1 contains suggested voltages that can be used as guides.
5.6.5 Attach ground wire from the instrument ground output terminal to the metal substrate and ensure positive electrical contact.
5.6.6 Make contact with the exploring electrode on the conductive substrate to verify that the instrument is properly grounded. This test shall be conducted periodically during' the test. The spacer test described in 5.6.4 shall also be repeated ifsignificant atmospheric changes take place during testing.
5.6.7 Move the exploring electrode over the surface of tlv dry coating at a rate ofapproximately 1 ft/s (0.3 m/s) using a single pass. Moisture on the coating surface may cause erroneous indications. If moisture exists, remove or allow dry before conducting test.
5.6.8 Discontinuities that require repair shall be identified with a marker that is compatible with the repair coating or one that is easily removed.
5.7 Verifying Operation of Equipment
5.7.1 Test the energy source (battery) for proper voltage output. Refer to the manufacturer's instructions.
5.7.2 Connect the exploring electrode and grounding cable to the terminals of the detectors.
5.7.3 Switch the instrument to the "on" position. 5.7.4 Touch the exploring electrode to the ground cable alligator clip. The instrument signal should actuate in accordance with the instrument manufacturer's operating instructions. 5.7.5 If the instrument fails to signal, it shall be considered defective.
5.8 Verifying Instrument Calibration
5.8.1 Verify instrument calibration in accordance with the manufacturer's latest published instructions. If out of cali bration, the instrument shall be calibrated in accordance with the instrument manufacturer's latest published instruc tions, or returned for calibration.
5.8.2 Perform field checking of the test voltage with the electrode placed, against the surface of the lining since tin. exploring electrode voltage may be reduced by the slight current flow of the lining.
5.8.3 If required, compare measured voltage with the selected test voltage. Depending on the type of tester, adjust the selected voltage 5 %.
6. Testing of Repaired Area
6.1 Sufficient drying or curing of the repair coating shall be allowed prior to retesting. The length of time required shall be obtained from the coating manufacturer.
6.2 Conduct the test following the procedures as previ ously outlined in this practice for the test instrument selected.
6.3 Retest only those areas that have been repaired, unless otherwise specified.

7.1 Prior to conducting an inspection of the coating
or proci ystems, the responsible organization shall ensure that the
e scope o: fiecessary services and equipment required for inspection are
if this r& provided. Factors that must be considered while planning the
ns is pef- Inspection activities include, but are not limited to, lighting,
Jccess to coated surfaces, cleaning surfaces of any deposit or
build up, ventilation and, where necessary, special under
water inspection requirements.
7.2 Station access procedures for Service Level I coating
|ystems monitoring shall be followed. While access proce
dures may vary from plant to plant, specific station access
procedures may include:
7.2.1 Security clearance for protected, radiation con-
trolled, and vital areas, and escorted or unescorted clearance
as required,
7.2.2 Radiological history including prior radiation expo
sure for all personnel involved,
7.2.3 Health, physics classroom training in the use of
radiation detection and monitoring devices and procedures
for wearing anticontamination clothing,
7.2.4 A radiation wqrk permit based on health physics
radiological survey of the work location,
7.2.5 Compliance with radiation work permit require
ments and other special radiation controls unique to each
work location, and
7.2.6 Issuance of dosimetry.
"
7.3 The safety requirements of the facility owner/operator
must be met when performing all inspection operations.
8. Personnel Requirements, Qualifications, and Training
8.1 The facility owner/operator shall specify the require ments and guidelines for qualification and training of inspection personnel involved in the program. However, inspectors and the coordinator shall be knowledgeable coat ings personnel meeting the requirements of ASTM Guide D4537 or ANSI N45.2.6. The coordinator shall, as a minimum, be a Level II Coatings Inspector.
8.2 The evaluator shall be a person knowledgeable and experienced in nuclear coatings work.
9. Inspection Plan
9.1 The owner/operator shall develop a plant specific inspection plan to accomplish the objectives of the moni toring program. A general visual inspection shall be con ducted on all readily accessible coated surfaces during a walk-through. After the walk-through, thorough visual in spections shall be carried out on previously desigfiated areas and on areas noted as deficient during the walk-through. A thorough visual inspection shall also be carried out on all coatings near sumps or screens associated with the Emer gency Core Cooling System (ECCSj. The inspection plan shall address the following based on specific owner/operator requirements:
9.1.1 A pre-inspection briefing to familiarize, all inspec tion personnel with objectives of the inspections, procedures to be followed, and precautions to be taken,
9.1.2 Monitoring team(s) assignments to specific areas for inspection(s), and
9.1.3 Location maps dividing the plant into identifiable areas for inspection activities to be issued to inspection teams. The maps shall also identify items/areas requiring special testing, if any. The locations of all defects and of all tests performed shall be recorded on the maps so that additional testing, recoating, and further monitoring may be performed.
9.2 During walk-through, visually examine coated sur faces for any visible defects, such as blistering, cracking, flaking/peeling, rusting, and physical damage.
9.2.1 Blistering--Compare any blistering found to the blistering pictorial standards of coatings defects (refer to Test Method D 714) and record size and frequency. If the blisters are larger than those on the comparison photographs, measure, record size and extent, and photograph. Report if blistered portions are intact.

9.2.2 Cracking--Cracking can be limited to the one layer of coating or extend through to the substrate. Measure the length of the crack or if extensive cracking has occurred,
measure the size of the area affected. Determine if the cracking is isolated or is part of a pattern. Record measure ments and describe crack depth and pattern on the inspec tion report. Photograph the area affected.
9.2.3 Flaking/Peeling/Delamination--Measure the ap
proximate size of the peels and note the pattern formed. Carefully test to see if lifting can be easily achieved beyond the obvious peeled area. Note all observations on the inspection report and photograph the area affected.
9.2.4 Rusting--Compare with the pictorial standards of Test Method D 610 to determine the degree of rusting. Try
to determine the source of rusting (that is, is it surface stain caused by rusting elsewhere, or is it a failure of the coating allowing the substrate to rust): Photograph the affected area and record observations on the inspection report.
9.2.5 If no defects are found, mark "Coating Intact, No Defects" on the inspection report.
9.2.6 If portions of the coating cannot be inspected, note the specific areas on the location map-inspection report, along with the reason why the inspection cannot be con ducted.
9.3 Written or photographic documentation, or both of coating inspection areas, failures, and defects shall be made and the process of documentation standardized by the facility owner/operator. Written documentation practice for inspection of coating system as given in Practices F 1130, F 3131, F1132, and F 1133 may be adopted as a guideline. Practice D4121 provides one method to obtain consistent, comparable close-up photographs.

3. Terminology
'3.1 mar resistance--the ability of a coating to resist damage caused by light abrasion. As just defined, it is a resistance of the surface of the coating to permanent defor mation, resulting from the application ofa dynamic mechan ical force.
4. Summary of Test Method
4.1 The materials under test are applied at uniform thickness to flat panels of uniform surface texture. After drying/curing, the mar resistance is determined by pushing the panels beneath a rounded stylus or loop that is loaded in increasing amounts until the coating is marred.
J This test method is under the jurisdiction of ASTM Committee D-l on Paints and Related Coatings and Materials and is the direct responsibility of Subcommittee D01.23 on Physical Properties of Applied Paint Films.
Current edition approved Oct. 15, 1991. Published December 1991, 2 Annual Book ofASTM Siundards, Vol 06.01.
5. Significance and Use
5.1 In some situations, marring of coatings applied to substrates under typical use conditions is unacceptable. This test method has been found useful in differentiating ih,, degree of marring of coatings on substrates. It is most usefij in providing relative ratings for a series of coated panels exhibiting significant differences in marring.

Sanding Procedure--Sand large face of stud with sandpaper, making certain that the surface is uni'y roughened. When sanding studs, sand straight up and rotate stud one quarter of a turn and continue ng. Make certain surface-of stud is flat but rough! While ng, keep stud face 'parallel to sandpaper. Non-planar lees cannot be used in testing because they lead to aiform bonding of the stud to the coated surface. Only planar) studs should be used in testing. Planarity may be sed by placing a stud on a flat surface and checking to 'f the stud wobbles. Careful preparation of studs is tial for good adhesive adhesion. . Cleaning Procedure--Place sanded studs in a large r.'Pour technical gride adefone over the Studs and swirl V to completely vvasli' studs. Pour out acetone and t the cleaning prpeedure. Soak the stud for at least 15 1 pour out acetone, and allow stiids to dry. S' Place washed and dried studs and beaker in an oven at )C and allow to heat for 1 h. Remove the beaker and s from the oven and allow to cool. DO NOT TOUCH
EOF STUDS. .4 Spread four drops of cyanoacrylate adhesive on the
face of an aluminum stud. Next, quickly press the stud J .the coated test substrate. Place a 2-kg weight on the stud insure good contact between the stud, adhesive, and "ace of the coating. Clean the excess adhesive from the e of the stud with a wooden applicator. Carefully remove [.weight after 2 min.
TU' 1--Substrate panels may be cut to any size that fits the
!ning device.
NVW' 2--When the'stud is pressed, excess adhesive should escape from under the stud. Excess adhesive buildup at the edge of the stud is a major source of error if allowed to dry. This excess must be removed from around the stud. The adhesive may he removed using a wooden applicator and an absorbent, creped, low-lint material.6 Some workers have found cotton swabs7 also work well when removing the excessive adhesive.
5.5 Allow the sample to cure for 2 h at room temperature.
NXY' 2--When reusing aluminum studs, the studs must be soaked in acetone to remove coating and resanded. It has been found that soaking the studs in two separate acetone baths thoroughly removes the adhesive and coating. The first acetone bath is used to dissolve the cyanoacrylate adhesive, and the second is used to further clean and dissolve any coating or adhesive left on the stud. Before the studs are used, they should be resanded and cleaned with acetone as specified in 5.2, 5.3, and 5.4.
5.6 Conditioning--Condition the coated substrates for at least 24 h at 23 2C (73.5 3.5F) and 50 5 % relative humidity, and test in the same environment or immediately on removal therefrom, unless otherwise specified by the purchaser and seller.
6. Procedure
6.1 Install the restrainingtdevice and upper adaptor in the tensile testei;.
. 6,2 Calibrate the tensile tester. Make sure that the chart speed is set at 8 to 20 in./min (20 to 50 cm/min). Make sure that the crosshead speed is set at 2 in./min (5 cm/min). Make sure that the chart full scale is set at 100 kg.
6.3 Place the specimen to be tested in the restraining device (Fig. 3 A arid 3 B). Pre-position the crosshead and then slowly lower it so the upper coupling adaptor can be attached to the test specimen. Take care to prevent the crosshead from impacting into the top of the specimen. Carefully attach the upper coupling adaptor to the stud (Fig 3 Q.
NXY' 3--When testing thin substrates, a piece of plastic may be placed in the restraining device behind the test specimen to prevent the
yanoacryiate adhesive such as Elmer's Wonder Bond Plus, or equivalent, has bund to be satisfactory for this purpose.
6 Kimwipes or equivalents, have been found satisfactory for this purpose. 1 Q-Tips or equivalents, have been found satisfactory for this purpose.

6.4 Turn on the chart recorder and pen. Start the tensile test. Stop the test when the stress returns to zero on the chart.
6.5' Examine test area on each specimen to determine the type of coating failure, rating it according to the following;
6.5.1 Adhesive failure of the coating at the substrate. A, 6.5.2 Cohesive failure in the coating, C, 6.5.3 Combination of adhesive failure at the coating/ substrate interface and cohesive failure in the coating, AC, 6.5.4 Adhesive failure at the stud, S, and 6.5.5 Combination of adhesive failure at the stud and cohesive failure in the coating, CS. For multilayer coatings, note if the failure, is between the layers. If so, label as CM. 6.6 Number and retain all test specimens For adhesion failure calculations. Test five specimens of each coated substrate one day and five on a second day. If one specimen differs significantly from the other four at the same time, fails because of an uneven (non-planar) stud, or for any other reason performs unlike the other four, test a replacement specimen.
NZ[' 4--Examine the stud and specimen carefully. Adhesive should
have been applied uniformly to the entire stud surface. Coating should have pulled off uniformly over the entire stud surface either with adhesive failure from the substrate (A) or cohesive failure in the coating (C). If failure is less than 90 % A or C or (or CM), if the adhesive has ' failed at the stud, retest exercising particular care in the specimen and stud preparation.
N\]' 5--The percentage of adhesive failure at the coating/substrate
interface is determined by inspecting the tested area on the substrate. This may be assessed by overlaying a transparent sheet grid marked in 0.10-in. (2.54 mm) squares and estimating the percentage of adhesive

failure in each square that lies over the tested area. These percental.,
may then be averaged to obtain failure for each specimen.

U Terminology
P3.1 Definitions of Terms Specific to This Standard: fS.1.1 abrasion resistance--resistance against the act of Heaping, smudging, or rubbing off. ' 3.1.2 abrasiveness--the degree to which a product tends M cause abrasion by the act of rubbing or scraping. , 3.1.3 receptor--film or paper of standard abrasiveness Ipnto which material removed from the specimen is deposited .^hiring the abrasion testing process. Alternatively, printed _ caper from which material is removed onto the specimen ghat has a higher degree of abrasiveness than the receptor (in case of testing abrasiveness).
L Summary of Test Method
i | 4.1 The test print and a receptor are sandwiched in the ^pancl holder of the GA-CAT Comprehensive Abrasion
| pester, clamped together with a known force, and made to slide over each other at a known frequency and over a Known distance for a predetermined time period,
jg 4.2 The test specimen is examined for degree of print ^degradation and the receptor for amount of ink or other "
terial transferred from the specimen surface. Results may rated relative to a comparative control run in the identical inner, or they may be quantified by comparison to a
This test method is under thejurisdiction of ASTM Committee D-I on Paints Related Coatings and Materials and is the direct responsibility of Subcomittee D01.56 on Printing Inks. Current edition approved Oct. 15, 1991. Published December 1991. 2 Annual Book ofASTM Standards, Vols 08.03 and 15.09.
ranking scale numbered from zero to ten (zero being the most abrasion resistant and ten the least abrasion resistant).
5. Significance mid Use
5.1 Abrasion resistance during transport and storage is essential to prevent marring of type matter, designs, or protective coatings on the exterior oflabels and other printed materials. Recognizing that the actual amount of abrasion occurring in the field depends on relative humidity, temper ature, tightness pf packing, and a host of other variables, this test method provides a rapid means for comparing the abrasion resistance of test surfaces under laboratory condi tions. It is useful for specification acceptance between the supplier and the customer.
5.2 This test method can also be used to evaluate the relative abrasion resistance of printed inks, varnishes, lami nates and substrates, and the abrasiveness of inks.
6. Apparatus
6.1 GA-CAT Comprehensive Abrasion Tester.3 6.2 Ranking Book3 containing specimens whose degree of nibofF is ranked from 0 (no rubofi) to +10 (most ruboff).
7. Materials
7.1 Standard Receptors, approximately 4 by 4 Vi in. (102 by 114 mm), of an appropriate grade, as follows;
7.1.1 C-P (least abrasive)--Glossy coated paper suitable for use with samples of low abrasion resistance.
7.1.2 A-l, A-3, and A-43-4 (intermediate abrasiveness)-- Imperial lapping film with aluminum oxide abrasive parti cles of different sizes (9, 12, and 30 pm, respectively).
7.1.3 A-63-4 (most abrasive), wet or dry, tri-um-ite 600. 7.1.4 B-23 (intermediate-abrasion resistance)--Printed single color paper suitable for measuring abrasiveness of samples of average abrasiveness (corrugated).
Nde' I--Other receptors may be substituted provided they have
equal abrasiveness on the same test specimens. Further research and experience may indicate a need for additional grades of standard receptors.
7.2 Foam Sheeting3 2 pieces, each approximately 2 mm in thickness and cut to 4 by 4*/2 in. (102 by 114 mm).
Nde' 2--Use of foam sheeting as a backing for the test specimen and
the receptor is recommended to provide uniform pressure over the test surfaces and to prevent ink, varnish, or other particles from becoming imbedded in the sensitive surface of the panel holders.

7.3 Comparative Control, a production or laboratory print preferably having known abrasion resistance. The compara tive control must have the same substrate, color(s), and subject matter as the test print.
8. Test Specimen and Conditioning
8.1 The specimen size in the grain direction (or flute in the case of corrugated board) must not exceed 4l/> in. (114 mm). The specimen size in the cross-grain direction is less critical; 4 in. (102 mm) is recommended. Care should be taken to avoid contaminating the test surface with finger prints during specimen cutting and handling.
8.2 Condition the specimens at 73.5 3.6F (23 2C) and 50 5 % relative humidity in accordance with Specifi cation E 171.
9. Preparation of Apparatus
9.1 Set the abrasion tester on a sturdy bench, preferably in a room conditioned at the temperature and relative humidity prescribed in 8.2. Make sure that the three-prong power cord is correctly connected,
9.2 Periodically, check the liquid level in the hydraulic pressure system. If not full, follow the instructions in the manufacturer's manual
9.3 If test conditions have not been specified, select an appropriate receptor by running the reference standard for the length of time required to achieve a visible level of degradation. Start with receptor C-l (7.1.1). If the test time exceeds 2 min, use a receptor with a higher level of abrasiveness.
Nfg' 3--Excessively long rubbing times are to be avoided because
they introduce uncontrollable heat development that can alter the results.
10. Procedure for Abrasion Testing
10.1 Loading the Instrument: 10.1. i Move the tray containing the four panel holders to the front black support shelf. Make sure that the inscribed "L" appears on the upper left side ofthe left panel holder and the "R" in the upper right side of the right panel holder (see Fig. 1). There should be space of at least V?. in. between the two center panel holders. 10.1.2 Face the test specimen on the receptor (selected in 9.3) and sandwich between the foam sheets. Place the sandwich between the two center panel holders so that the

within laboratory coefficient of variation was found to be 0.51 % relative at 9 df and the between laboratory coefficient of variation was 1.04 % relative at 6 df. Based oh these coefficients the following criteria should be used for judging the acceptability of results at the 95 % confidence level:
8.1.1 Repeatability--Two results, each the. mean of dupli cate determinations obtained by the same operator on different days, should be considered suspect if they differ by more than 1.62 % relative.
8.1.2 Reproducibility--Two results, each the mean of duplicate determinations obtained by operators in different laboratories should be considered suspect if they differ by more than 3.59 %.
8.2 Bias--Bias has not been determined.

Standard Practice for
Calculating Formulation Physical Constants of Paints and Coatings1
This standard is issued under the fixed designation D 5201; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (0 indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This practice describes procedures for calculating weight solids, volume solids, solvent content, and density of liquid paints and coatings based on formulation data (not from analytical determinations). These calculations may be related to either as-supplied (unreduced) or as-applied (re duced) coating materials, including multicomponent types.
1.2 These values may not be acceptable for regulatory gurposes.
1.3 Calculated values for these physical constants are used in the coatings industry for developing lower volatile organic compound (VOC) paints, making comparisons, etc.
1.4 The calculations described in this practice are based on the following assumptions: (1) Solids (nonvolatile) con tent and density of the individual ingredients (raw materials or intermediates, or both) have been established by appro priate analytical methods (see Test Methods D 153, D 1475, D2369, D 4558, and Guide D 2832), and (2) The blended formulation behaves as an ideal solution with no volume change on mixing (see 6.2).
1.5 In calculations involving the liquids in a formulation, those volatile liquids that are incorporated primarily for vehicle solvency and control of the application characteris tics should be classified as solvents. This would include solvents normally used to adjust viscosity for application and appearance of the coating. Liquids that are expected to be retained in the dried film to affect the final performance properties should be classified as part of the coating solids.
No t ' 1--For regulatory VOC purposes, use EPA Reference Method 24 and ASTM standards listed, or state regulatory requirements (see EPA 450/3-88-018).
1.6 Volatile by-products of cross-linking reactions (cure volatiles) are not considered in;these calculations since the object of this practice is to define paint physical constants based on formulation information.

multiplying by tl9.84.
5.6 Paints Reducedfor Application: 5.6.1 The calculations and examples shown in 5.1 through 5.5 are for as-supplied materials intended for use without further reduction. The same calculations can be used for determining the formulation density, percent weight solids content, percent volume solids content, and solvent (VOC) content of materials that have been reduced for application. It is only necessary to know the amount of reduction (volume or weight) and the density of the reducing solvent. The reducing solvent then becomes an additional ingredient in the paint formulation.
5.6.2 Each of the following examples is based on jjequation:

6. Precision and Bias
6.1 No statement is made about either the precision or bias of this practice for calculating formulation physical constants since the results are obtained strictly by mathemat ical calculations and will be related to the accuracy of the data used and conformance to the prescribed calculations.

Designation: E 97 - 82 (Reapproved 1987)
Standard Test Method for
Directional Reflectance Factory 45-deg 0-deg, of Opaque Specimens by Broad-Band Filter Reflectometry1
This standard is issued under the fixed designation E 97; the number immediately following the designation indicates the year of original adoption or, in the case ofrevision, rise year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<s) indicates an editorial change since the last revision or reapproval.
This method has been approvedfor use by agencies oftheDepartment ofDefense andfor listing in theDoD Index ofSpecifications and Standards.
1. Scope
1.1 This method covers the determination of the 45-deg, 0-deg directional reflectance factor ofnonfluorescent opaque specimens by means of filter photometers. To obtain similar results from spectrophotometers, see Method E 308.
Nz{' l^=The values stated in inch-pound units are to be regarded as
the standard.
N|}' 2--This method has been developed for determining (1) the
daylight luminous reflectance factor of paint, opaque white porcelain enamels, and ceramic whitewares; and (2) the blue-light reflectance factor (sometimes called "brightness") of uncolored papers and pulps in sheet form. The method may also be used for determining the reflectance factor of other opaque specimens.
N~' 3--The blue-light reflectance factor of paper provides a
measure of freedom from yellowness such as results in pulp and paper from the presence of lignin and other so-called impurities left by incomplete bleaching.
N' 4--Blue-light reflectance factor by this method differs slightly,
both spectrally and geometrically from the TAPPI Stahdards T 217 and T 452. The TAPPI methods are considered to be standard for the pulp and paper industry when brightness measurements are to be made.
1.2 This standard may involve hazardous materials, oper ations, and equipment. This standard does not purport to address all ofthe safety problems associated with its use. It is the responsibility ofwhoever uses this standard to consult and establish appropriate safety and health practices and deter mine the applicability of regulatory limitations prior to use.

3. Significance-and Use
3.1 Measurements of reflectance factor provide a measure of the amount of incident radiation reflecting diffusely under the geometric conditions of this method. High values indi cate low absorption. When the response of the detector conforms to the sensitivity of the average human eye (Y-tristimulus filter), the result is designated luminous reflec tance. For near white specimens, the reflectance value for blue light (Z-tristimulus filter), provides a relative index of freedom from yellowness for a particular type of material.
3.2 This method is frequently used to evaluate near-white, diffusely reflecting materials such as paint, paper, and powders.
4. Terminology
4.1 reflectancefactor--ratio of flux reflected from a spec: imen to the luminous flux reflected from a standard surface, under the same geometric conditions of measurement. Unless otherwise indicated, the-standard surface is assumed to be a perfect reflecting diffuser. If some real surface is used, the quantity measured is called "relative reflectance factor."
4.2 daylight 45-deg, 0-deg luminous directional reflectance factor--the ratio of the luminous flux from a specimen illuminated at an angle of 45 deg and viewed perpendicularly by the equivalent of CIE standard source C and the 1931 CIE standard observer, to the luminous flux from the perfect reflecting diffuser, similarly illuminated and viewed (see Definitions E 284).
N' 5--The combination of illumination at 45-deg and viewing at
0-deg (perpendicularly), designated 45/0, or the converse designated 0/45, has been selected as being representative of average conditions of illuminating and viewing. This reflectance factor determines which of

Sscribed in Section 11. In general, commercial instruments do not
nform exactly to the apparatus requirements. The suitability of a
ven instrument depends in large measure on the spectral selectivity of
'e specimens being measured, and on the availability of standards of
rtnilar reflectance and spectral character.7 8
Standards
. 6.1 Primary Standard--The primary standard for reflec* nee is the perfect reflecting diffuser as described in Definiions E 284. It is assigned a value of 100 for the conditions of ,5-deg illumination and perpendicular view.
6.2 Secondary Standards8--Porcelain-enameled metal plaques, or other materials known to be reasonably perma nent in reflectance and uniform over the surface, may be calibrated and used as secondary reflectance standards.
7. Preparation of Test Specimens
7.1 Paint--Unless otherwise specified, prepare panels for the determination of reflectance factor by applying the paint to a suitable flat background with a doctor blade in accord ance with Test Methods D 823. Use sufficient thickness so that additional coats produce no measurable change in reflectance factor. Allow 72 h for the.paint to dry. It is recommended that 60-deg gloss as described in Test Method D 523 and unusual surface structure be noted.
7.2 Porcelain Enamel--Laboratory-prepared specimens, articles of commerce, or sections cut from articles of commerce may be tested. The area to be tested shall be flat and reasonably free of surface defects. Laboratory specimens shall be at least 60 by 90 mm (2 Vi by 3V2 in.) in size; however, specimens 100. by 100 mm (4 by 4 in.) are preferred.
N' 9--The method ofpreparation of the specimen, such as weight
of application or firing treatment, may affect the reflectance factor but is not a part of this test method- however, each manufacturer should investigate the effect of such variables on the reflectance factor of his products (see Test Method C 347).
7.3 Paper--Sample in accordance with Test Methods D 585. Handle the test specimen carefully to avoid soiling, and take care not to touch the areas to be tested. The test specimen shall consist of a pad of sheets sufficiently thick that doubling the number of sheets causes no measurable change in reflectance factor.
7.4 Other Materials--Prepare test specimens of materials other than those listed in 7.2 and 7.3 in accordance with accepted practice,, and record the method of preparation in the report.
N' 10--All high-reflectance diffusely reflecting materials are
somewhat translucent since most of their reflectance is due. to internal scattering. Roughly 95 % of the incident light is transmitted through the surface, and partially absorbed. What is not absorbed is multiply scattered back to the surface, at a point different from the point of incidence, where it is retransmitted as reflected light. The maximum distance between the points of incidence and exitance is primarily a function of the extinction coefficient of the material. For materials such as most white paints and porcelain enamels, the extinction coefficient is large, and the maximum distance of travel is small, and errors due to this internal travel' may be small enough to be neglected. Other high-reflectance materials, such as opal glass and white plastics, may have smaller extinction coefficients, and the maximum distance of internal travel may be large enough (several millimetres is not un common) that significant light losses can occur unless the reflectometer has been designed to eliminate such losses. The maximum errors occur in measurements of reflection factor when comparing sample and standard of markedly different extinction coefficients. See NBS Tech nical Note 594-12 (Oct. 1976) fora detailed discussion of such losses.

8.Procedure
8.1 Operate the reflectometer in accordance with the instructions supplied by the manufacturer, including line voltage, warm-up time, and adjustment of the scale.
8.2 Use a standard having a reflectance factor close to that of the test specimen or, if several specimens having a small range of reflectance factor values are being tested, use at least two standards, preferably at the extremes of the range being measured. Use a green filter for luminous reflectance factor; a blue filter for blue-light reflectance factor of paper or other materials; and, when specified, other filters for reflectance factor for other kinds of light, such as an amber filter for amber-light reflectance factor, etc.
N' 11--In general, instrumental errors are related to the differ
ences in reflectance factors and spectral characteristics between specimen and standard. For greatest accuracy, standards close in reflectance factor and similar in spectral characteristics to the specimens should be used. The same area of standard should be measured as that used for its calibration.
8.3 Obtain the instrument readings for the standards and then for the specimens, in turn; read the specimens in reverse order, and finally read the standards again.
8.3.1 Paper Specimens--Make readings with the blue filter on at least five separate sheets, and equal numbers of readings parallel to and at right angles to the machine direction of the paper on both sides of the sheets.
8.3.2 Porcelain-Enameled Specimens--Make reflectance factor readings with the green filter on an area not less than that ofa circle 70 mm (2% in.) in diameter. A determination shall comprise a sufficient number of readings so that the average of successive determinations can be reproduced with a difference between the highest and lowest determinations, not exceeding 0.5 % on the scale for which the perfect reflecting diffuser is assigned a value of 100 (see 6.1). Instruments covering areas smaller that that prescribed may be used, provided a sufficient number of well-distributed readings is taken so that the average reflectance factor is determined within the spread prescribed for repeated deter minations on a given specimen.9
9.Calculation
9.1 Calculate the mean value for the readings on each standard and specimen.
9.2 Calculate the reflectance factor of each specimen according to the directions of the instrument manufacturer. Apply corrections for scale nonlinearity, if available. In the
absence of more explicit instructions, calculate the specimen reflectance factor as follows;
U = (RJb)
where: R = reflectance factor of the specimen for the filter used c = mean instrument reading for the specimen, b = mean instrument reading for the standard used, and Rs = assigned reflectance factor of the standard for the filter
used.
N' 12--The scale linearity of an instrument may be checked by
reading the reflectance factors of a series of ten or more nonselective standards ranging from 85 to 0.5 %.s
10. Report
10.1 Report values of reflectance factor in percent relative to the perfect reflecting diffuser as 100 (as defined by U.Si National Bureau of Standards). The result is described as "45-deg, 0-deg directional reflectance factor." When the green filter is used, the words "daylight luminous" shall be inserted before "directional." When the blue or amber filters are used, the phase "for blue light" or "for amber light," respectively, shall be added after "reflectance factor." Report reflectance factor values to the nearest 0.1 %. For paper' specimens, report values for the wire and felt sides separately.'1
10.2 Describe or otherwise identify the method of pre paring laboratory specimens.
10.3 Identify the reflectometer used by the manufacturer's name, the model, and the serial number.
\
11. Precision
H.l Precision (Repeatability and Reproducibilityj^'R.epeatability is the deviation from mean experienced when measuring a single specimen on a single instrument. Note' ^ that with many samples measured, excessive nonuniformity' ; by area, or by method of presentation to the instrument, is' the chief factor limiting repeatability. Reproducibility is the deviation from mean experienced between different instru ments employing calibrated standards of nearly the same reflectance factor. Refer to Table 1.

The internationally accepted standard of reflectance is the perfect reflecting diffuser. This ideal reflecting surface reflects 100 % of the radiant power incident ori it such that the radiance is the same for all directions within the hemisphere of solid angles. No physical realization of this standard exists. Optical properties of standards prepared from pressed plaqties of magnesium carbonate (MgC03), barium sulfate (BaS04), or polytetrafluoroethylene (PTFE) can approximate those ofthis ideal standard. For further information see CIE Publication No. 46 (l).2 The principal use of a white reflectance factor standard is to transfer an absolute scale of reflectance to a more
durable material or from one instrument td another. In theory, this transfer, done from first principles, should-be quite easy. In practice, values are likely to be required for parameters that are
unknown, proprietary; or require a highly sophisticated level of skill. Some, but not all, of those parameters are discussed in this practice.
Scope
1.1 This practice covers procedures for preparing pressed iwder transfer standards of reflectance factor. .These stan ds can be used in the near-ultraviolet, visible and near
ed region of the spectrum. Procedures for calibrating reflectance factor of materials on an absolute basis are intained in CIE Publication No. 44 (2). Pressed powder .tidards are used as transfer standards for such calibrations tuse they have a high reflectance factor wfhichis nearly <nstant with wavelength and because the distribution of fleeted flux resembles that from the perfect reflecting iffuser. 1.2 This standard does not purport to address all of the ifety problems, if any, associated with its use. It is the isponsibility ofthe user of this standard to establish appro bate safety and health practices and determine the applica|/hy ofregulatory limitations prior to use. 1.3 The values stated in SI units are to be regarded as the Ijkndard. The values in parentheses are for information only.

3. Terminology
3.1 Definitions--All terms used in this practice are consis tent with Terminology E 284. The following three definitions are particularly important to this practice:
3.1.1 reflectance--the ratio of the flux reflected from a specimen to the flux incident on the specimen.
3.1.2 perfect reflecting diffuser--ideal reflecting surface that would neither absorb nor transmit light, but would reflect diffusely, with the radiance of the reflecting surface the same ,for all reflecting angles, regardless of the angular distribution of the incident light.
3.1.3 reflectancefactor--the ratio of flux reflected from a specimen to the flux reflected from a standard surface, under the same geometric conditions of measurement. Unless otherwise indicated, the standard surface is assumed to be the perfect reflecting diffuser.
4. Summary of Practice
4.1 Procedures are given for the preparation of white reference standards of diffuse reflectance factor. The recom mended materials are white powders that are pressed into plaques. These plaques provide close approximations to the optical properties of the perfect reflecting diffuser, and may be used to transfer a scale of absolute reflectance to another material or to an instrument.
4.2 Previous editions of this practice included guidelines for the preparation of standards from magnesium oxide smoke. Preparation of this type of standard is no longer recommended. The ease of preparation, physical ruggedness.

and photometric stability of pressed powder plaques make them far superior to smoked magnesium oxide plaques as reflectance factor standards.
5. Significance and Use
5.1 All commercial reflectometers measure relative reflec tance. The instrument reading is the reflectance factor, the ratio of the light reflected from a reference specimen to that reflected from a test specimen. That ratio is dependent on specific instrument parameters.
5.2 National standardizing laboratories and some research laboratories measure reflectance on instruments calibrated from basic principles, thereby establishing a scale of absolute reflectance as described in CIE Publication No. 44 (2). These measurements are sufficiently difficult that they are usually , left to laboratories that specialize in them.
5.3 A standard that has been measured on an absolute, scale could be used to transfer that scale to a reflectometer. While such procedures exist, the constraints placed on the mechanical properties restrict the suitability of some of the optical properties, especially those properties related to the geometric distribution ofthe reflected light Thus, reflectance factor standards which are sufficiently rugged and cleanable to use as permanent transfer standards depart considerably from the perfect diffuser in the geometric distribution of reflected radiance.
5.4 The geometric distribution of reflected radiance from a pressed powder plaque is sufficiently diffuse so that such a standard can provide a dependable calibration of a direc tional-hemispherical reflectometer. Although pressed powder standards are subject to contamination and breakage, the directional-hemispherical reflectance factor of pressed powder standards can be sufficiently reproducible from specimen to specimen made from a given lot ofpowder, so as to allow one to assign absolute reflectance factor values to all the ppwder in a lot.
5.5 This practice describes how to prepare white reflec tance factor standards from a powder in a' manner that allows a standardizing laboratory to assign the absolute scale of reflectance to the powder.
6. Apparatus
.6.1 The basic apparatus for producing a pressed powder standard includes a powder press, powder containers and a balance. There are presently two commercial suppliers of powder presses.6 The press and receptacles can also be made in a local machine shop. A suggested configuration is shown in Fig. 1. The optical surface of the plaque should be pressed against a surface of ground glass or polyfmethyl methacrylate) to provide a matte finish on the pressed plaque. Powder receptacles should be at least 5 mm deep for BaS04 and at least 10 mm deep for PTFE.

highest purity. It should be specially refined for optical and spectroscopic use (3).7
8.2 Polytelrqfluorpethylene--the PTFE (4)8-9-10 should also be specially refined for optical and spectroscopic use but some commercial grades have been found, to be acceptable substitutes. There is currently no commercial source for small quantities of optical grade PTFE .powder. Large quantities (drums) of commercial grade PTFE can be ob tained from the manufacturers.
9. Procedure 9.1 All powdered reflectance standards should be stored m
tightly capped glass containers. If the powder is purchased m plastic containers it should be.transferred to a glass container' as sooii as possible. Before using the powder, it should be* placed in a glass blender equipped with stainless-steel or PTKE-coated blades and pulverized to a uniform consis tency. The quantity of powder to be used should be transferred with stainless steel or PTFE-coated spoons, The wholeoperation should be performed in a draft-free location, away from sources of small particulate contamination, filters, sweaters, windows, ovens, etc. All measurements (weight, height, width, depth; volume, area, etc.) should be performed with adequate precision to ensure that the final density is within 5 % of the specified value. The'iftost . reproducible standards are made by pressing the powder to a specific density. Thus, the mass of the powder to be used should be determined from the volume of the receptacle.
9.2 Barium Sulfate--BaS04 should be pressed to a den sity of 2000 kg/m3 (2.0 gm/cm3) and a thickness of at least 5 mm. Several specimens should be pressed in succession. Matched pairs should be selected to be representative of the contents of the bottle ofpowder. The pressed plaques should be kept in a covered desiccator when not in use.

leflectance Standard.6 [9.3 Pofytetrafluorethylene--PTFE should be pressed to a
Snsity of 1000 kg/m3 (1.0 gm/cm3) and a thickness of at

use. PTFE can be very sensitive to particulate contamination and electro-statically attracts airborne particles. Such con tamination can make the material slightly fluorescent and reduce its reflectance in (he ultraviolet spectral region. Table 2 lists the 6/diffuse reflectance factor values for PTFE as determined by the National Institute of Standards and Technology (NIST).
10. Precision and Bias
10.1 The National Institute of Standards and Technology and the Inter-Society Color Council Project Committee 22, Materials for Instrument Calibration, have carried out col laborative tests to determine the precision and bias of the preparation of PTFE reflectance factor standards (5). The standard deviation of three determinations of the reflectance factor of PTFE by the NIST ranged from 0.0002 to 0.0008 over the spectral range 300 to 1000 nm. The measured reflectances of PTFE from two manufacturers exhibited differences of from --0.002 to +0.004 over the same range with the largest differences near the ends of the.range and a constant measurement uncertainty of 0.005. From the 9 laboratories participating in the round-robin experiment, 17 specimens were returned. The results are shown in Table 3 for the wavelength range 300 to 1000 nm.
10.2 CIE Publication Number 46 (6) cites literature references on the reproducibility of BaS04 pressings that range from 0.05 % to 1.0 % with the most common value in the range about 0.2 %. This puts the reporducibility of the plaque preparation near the level of the reproducibility of the international standardizing laboratories' ability to charac terize the absolute reflectance of the material.

Such usage is not assumed in this' method. The definition
may require that the term be modified by adjectives denoting
the spectral and geometric conditions of measurement.
3.1.1.2 reflectancefactor, R, n--ratio of the flux reflected
from the specimen to the flux reflected from the perfect
reflecting diffuser under the same spectral and geometric
conditions of measurement. (E 284)
3.1.1.3 gloss reflectance factor,
n--ratio of the
specularly reflected part of the, (whole) flux reflected from the
specimen to the flux reflected from a specified gloss standard
under the same geometric and spectral conditions of mea

3.1.2.1 gloss, n--angular selectivity of reflected light,
responsible for the degree to which reflected highlights or
images of objects may be seen as superimposed on a surface.
(E 284)
(1) Discussion--Gloss is responsible for the object's glossy
appearance, not for an observer's perception of the appear
ance. At least six types or characteristics of gloss may be
observed depending upon the character of the surface and
the spatial distribution of the reflected light (3).
3.1.2.2 specular gloss, n--ratio of flux reflected in
specular direction to incident flux for a specified angle of
incidence and source and receptor angular apertures. (E 284)

3.1.4.1 aperture angle, 2h n--angle subtended at a point
on a specimen by the maximum dimension of the illumi
nator or receiver, within which the flux in a directional beam
is contained.
(1) Discussion--In optics, the symbol k is used for the

half angle; hence the recommended symbol here is 2h (E 284)
3.1.4.2 goniopkotometer, n--instrument that measures flux as a function of angles of illumination or observation. (E284)
3.2 Terms Specific to This Test Method: 3.2.1 Terms Relating to Reflection Haze: 3.2.1.1 reflection haze, H, n--for a specified specular angle, ratio of flux reflected at a specified angle (or angles) from the specular direction to the flux similarly reflected at the specular angle by a specified gloss standard. (1) Discussion--Modifiers may. be used to specify the angles at which the haze is measured (for example, 2" or 5); whether H or a logarithmic form is to he stated; or whether H is to be compensated for the luminance of the specimen by multiplication by I'sp-cmcn/T',,, where n denotes the reference white; or any combination of these. 3.2.2 Terms Relating to Metallic Reflection: 3.2.2.1 metallic brightness, n--freedom of a metal surface from diffuse haze or texture. 3.2.3 Terms Relating to Specimen Directionality: 3.2.3.1 `with-machine' direction, n--the axis of a spec imen that is parallel to the direction of mill rolling or extrusion, or other surface-finish texture. 3.2.3.2 'across-machine' direction, n--the perpendicular to `with-machine' direction. 3.3 Other appearance terms and definitions in Termi nology E 284 are applicable to this test method.
4. Summary of Test Method
4.1 Several geometrically different measures of light re flected by a surface are proposed for use in describing its gloss appearance. In Test Method A, gloss reflectance factor is measured at 30 to the specimen normal using narrow illuminator and receiver aperture angles (0.5 wide max imum). Distinctness-of-image gloss is measured at 29.7 or 30.3 or both. Narrow-angle (2) reflection haze is measured at 28 or 32or both, and wide-angle (5) reflection haze at 25 or 35 or both. The ratio of reflectance factors for 28 or 32 or both, perpendicular and parallel to the machine direction of the specimen, is computed as a measure of directionality. In Method B, specular gloss is measured at 20 according to Test Method D 523, and narrow-angle reflection haze is measured at 18.1 and 21.9.5
5. Significance and Use
5.1 The gloss of metallic finishes is important commer cially on metals for automotive, architectural, and other uses where these metals undergo special finishing processes to produce the appearances desired. It is important for the end-products which use such finished metals that parts placed together have the same glossy appearance.
5.2 It is also important that automotive finishes and other high-gloss nonmetallic surfaces possess the desired finished appearance. The present method identifies by measurements important aspects of finishes. Those having identical sets of numbers normally have the same gloss characteristics. It usually requires more than one measurement to identify properly the glossy appearance of any finish (see Refs 3 and
*)

10. Procedure
10.1 Bring the specimen to the instrument for measure ment. Be sure the specimen is flat.
10.2 For Test Method A, be certain that the specular sensor is centered on the spee'imeh-reflected specular light beam. One type of instrument, illustrated, in Fig. 1A, provides for screw-controlled movement, of the receptor assembly to achieve this centering. The full goniophotometer, shown in Fig. 2, identifies the specular direction by the peak of the goniophotometric curve.

Standard Test Methods for Cathodic Disbonding of Pipeline Coatings1
This standard is issued under the fixed designation G 8; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (<) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 These test methods cover accelerated procedures for
simultaneously determining comparative characteristics of
insulating coating systems applied to steel pipe exterior for
the purpose of preventing or mitigating corrosion that may
occur in underground service where the pipe will be in
contact with inland soils and may or may not receive
cathodic protection. They are intended for use with samples
of coated pipe taken from commercial production and are
applicable"to such samples when the coating is characterized
by function as an electrical barrier.
1.2 This test method is intended for testing coatings
submerged or immersed in the test solution at room temper
ature. When it is impractical to submerge or immerse the test
specimen, Test Method G 95 may be considered where the
test cell is cemented to the surface of the coated pipe
specimen. If higher temperatures are required, see Test
Method G 42. If a specific test method is required with no
options, see Test Method G 80.
1.3 The values stated in SI units to 3 significant decimals
are to be regarded as the standard.
.
1.4 This standard does not purport to address all of the
safely problems associated with its use. It is the responsibility
of whoever uses this standard to consult and establish
appropriate safety and health practices and determine the
applicability ofregulatory limitations prior to me.

impressed current system. The coating is perforated before starting the test.
3.1.1 In Method A, a magnesium anode is used with no electrical monitoring during the test period. The results are determined by physical examination after the test period is concluded.
3.1.2 In Method B, either a magnesium anode or an impressed current system may be used. Electrical instrumen tation is provided for measuring the current in the cell circuit. The electrical potential is also measured, and upon conclusion of the test period, the test specimen is physically examined.
3.1.3 In both test methods physical examination is con ducted by comparing the extent of loosened or disbonded coating at the perforations in the immersed area with extent of loosened or disbonded coating at a new test hole in the coating made in an area that was not immersed.
4. Significance and Use
4.1 Breaks or holidays in pipe coatings may expose the pipe to possible corrosion, since after a pipe has been installed underground, the surrounding earth will be more or less moisture-bearing and it constitutes an effective electro lyte. Damage to pipe coating is almost unavoidable during transportation and construction. Normal soil potentials as well as applied cathodic protection potentials may cause loosening of the coating, beginning at holiday edges, in some cases increasing the apparent size of the holiday. Holidays
may also be caused by such potentials. While apparently loosened coating and cathodic holidays may not result in corrosion, this test provides accelerated conditions for loos ening to occur and therefore gives a measure of resistance of coatings to this type of action:--
4.2 The effects of the test may be evaluated by either physical examination or monitoring the current drawn by the test specimen or both of, these two. Usually there is no correlation between the two methods of evaluation but both methods are significant. Traditional physical examination consists of assessing the effective contact of the coating with the metal surface in terms of observed differences in the Relative adhesive bond. It is usually found that, the electrically stressed area propagates from the holiday to a boundary where the loosened coating leaves off for the more effective contact or bond attributed to an original condition throughout the specimen before electrical stressing was applied. Assumptions associated with test results include the following:
4.2.1 Attempting to loosen or disbond the coating at a new test hole made in the coating in an area that was not immersed represents maximum adhesion or bond as mea sured by the lifting technique used, and that the same lifting

comparative basis, but disbondment tier se jn this test is
ot necessarily an adverse indication. The virtue of this test
; that all dielectric type coatings now in corhmon use will isbond to some degree thus providing a means of com-
Jparing one coating with another. Bond strength is more Important for proper functioning of some coatings than
others and the same measured disbondment fortwo different
[coating systems may not represent equivalent loss of corro
sion protection.
| 4.2.3 The amount of current in the test cell js a relative
y indicator of the extent of areas requiring protection against
^ corrosion; however, the current density appearing in this test
" is much greater than that usually required for cathodic
protection in natural, inland soil environments.

,
7.1 The test specimen shall be a representative piece df production-coated pipe. One end shall be plugged or capped, and sealed.
7.2 One or three holidays shall be made-in each specimen. Three holidays are recommended. Recommended dimen sions are given in Fig. 5. A specimen with one holiday shall have it drilled in the middle of the immersed length. If three holidays are used, they shall be drilled 120 apart with one in the center and the other two at locations one fourth the distance from top and bottom of the immersed test length. Each holiday shall be drilled so that the angular cone point of the drill will fully enter the steel where the cylindrical portion of the drill meets the steel surface. The drill diameter shall be not less than three times the coating thickness, but it shall never be smaller than 6.35 mm (0.250 in.) in diameter. The steel wall of the pipe shall not be perforated. With small- i diameter pipes, where there is danger of perforating the pipe, the holiday shall be started with a standard 60 cone point and finished with a drill that has had a substantial portion of the cone point ground away.

7.4 The specimen test area shall consist of the area between the edge, of the bottom end seal and the immersion line. The bottom end seal area shall not be considered part of the area tested. Any suitable diameter arid specimen length of pipe may be used, but the immersed area shall be not less than 23 227 mm2 (36 in.2). An area of 92 900 mm2 (1 ft2)' has been found preferable when convenient.8
8.Specimen Preparation
8.1 Before making artificial holidays, verify the continuity of the coating and the effectiveness of the end-cap seal as follows:
8.1.1 Immerse the test specimen and a metallic electrode in the electrolyte. Connect one terminal of the multimeter to the test specimen and the other terminal to the metallic
electrode. Measure the apparent resistance in ohms, making two determinations: one witjithe specimen connected to tbi positive terminal of the multimeter; and one with thi specimen connected to the negative terminal.
8.1.2 Disconnect the specimen from the multimeter but leave it immersed for 15 miti. Then-measure the resistana again as in 8.1.1.
8.1.3 A significant decrease in either resistance reading after 15'min will indicate a flaw in the coating or end-cap -seal! Reject the specimen if the `flaw is identified in the coating. If the flaw is in the end-cap seal, it may be repaired and the resistance remeasured as in 8.1.1 and 8.1.2.
8.1.4 The lowest resistance after 15 min of immersion shall be not less than 1000 M2 but a stable reading below 1000 Mil may not indicate a flaw and the specimen may be usbd for''test. All resistance measurements shall be reported in the results.
8.2 Record initial holiday diameter(s). 8.3 Measure and record the minimum and maximum coating thickness in accordance with Method G 12, and the

N' 2--The use of a transparent film having a grid laid out in small
squares such as 2.54 mm (0.1 in.) on a side has been found useful. The film is placed against the unsealed area and the boundary of the unsealed area traced on the grid. The area is then obtained by counting the squares within the bonded area.10
10. Procedure for Method B
10.1 In addition to the procedure given in Section 9, monitor the progress of the test electrically in accordance with the schedule given in 10.2 as follows:
10.1.1 If a magnesium anode is to be used, install the test assembly shown in Fig. 2. If impressed current for a single specimen is to be used, install the test assembly shown in Fig. 3; if more than one specimen is to be tested, use the modification shown in Fig. 4.
10.1.2 Measure E2, the stress potential in volts between test specimen and reference electrode, with a multimeter without disconnecting the anode from the test specimen. Use the instrument described in 5.1.5. If a CuCuS04 electrode is used, immerse only temporarily.
10.1.3 Measure /,, the current demand in amperes, by
determining the potential drop across the 1-S2 resistor perma nently installed in the test cell circuit with the multimeter described in 5.2.1. The voltage reading will be numerically equal to amperes.
N' 3--An alternative method of measuring current demand may
be used by means of the instrument described in 5.2.4. In this method, the jyire connection between test specimen and anode is temporarily broken and a zero-resistance ammeter temporarily interposed between the specimen and the anode. Reconnect the specimen to the anode with the connector wire as soon as this measurement is completed.
this with the multimeter described in 5.1.5 connected
between the test specimen and the reference' electrode'as
follows:
.....--
10.1.4.1 Disconnect the anode from the test specimen
while closely observing the multimeter. As the instrument
pointer falls, it will dwell significantly at the polarized value
before receding further. The dwell point is . If a CuCuS04
electrode is used, immerse only temporarily. :
10.2 Electrical Monitoring Schedule:
10.2.1 Eleotrical measurements at the start of the test are
defined as the average of measurements taken on the second
and third days after immersion. Measurements may be taken
on the day of immersion in order to ascertain functioning of
the test ceil, but such measurements are not to be used in
calculating the change in characteristics from start to target
dates in the conduct of the test.
10.2.2 Make electrical measurements at the start of a test
and on a target date after 30 days. The test may be continued
for 60 or 90-day targets with intermediate and corresponding
electrical measurements.

12.1 Precision data are limited to two adjacent specimens taken from the same production-coated pipe and assume that the production process was uniform with respect to pipe surface condition and coating material. Specimens that were not adjacent in the as-produced condition. or were taken from different lengths ofpipe may represent differing process conditions. The following data should be used forjudging the acceptability of results: (These precision data are approxima tions based on limited data, but they provide a reasonable basis forjudging the significance of results.)

|.2, Referenced Document
2.1 ASTM Standard: G12 :Test Method for Nondestructive Measurement of ,, Film Thickness of Pipeline Coatings on Steel2
jt>3. Summary of Method
'3.1 The method consists of an immersion-type test where pipe specimens are suspended in ah aqueous electrolyte for Ithe duration of the test period. Electrical measurements of Icoating capacitance and dissipation factor are used to follow ithe water absorption rate Of the test materials.
1`4. Significance and Use
4.1 The deterioration of an insulating coating film is . intimately related to its moisture content. The water penetraf-tion test provides a means for monitoring the passage of jmoisture through a coating material by means of changes in Bits dielectric constant. When expressed in relation to time, the test data will reflect a rate of deterioration which is a 3a characteristic of the coating material and will bear a'relatioii to its expected useful life as an insulating coating. The test for |water penetration will also provide information that is useful |in establishing the optimum coating thickness for a given s material.
j 5. Apparatus
i 5.1 Immersion Cell--Any suitable rionmelallic vessel to j contain the test specimens. Dimensions of the vessel shall , permit the following requirements:
5.1.1 Test specimens shall be suspended vertically with at least 25 mm (1.0 in.) clearance from the sides and bottom.

,
j.2.1 The end-cap material shall have a dielectric constant
he range from 2 to 6, bond well to the coating surface,
exhibit a low water-absorption rate. Several commer-
|ly available poly(vinyl chloride)-paraffin compounds,4 Jwell suited for this purpose. They have a melting point in
: 150 to 200C (300 to 390F) range, can be poured into
lids around the pipe sample, and appear as resilient,
able solids at room temperature.
N' 4--Using these materials, the end-caps can be applied to the
iired thickness by repeated dipping of the sample ends into a
Bten-wax bath, or through the use of light-weight, disposable molds of gjninum foil or paper formed around the pipe sample to allow the ling of the caps directly to the surface of the coated pipe sample.
16.3 The end of the specimen which will protrude above
i immersion line shall be provided with a suitable means gjsupport and a separate wire connection for electrical
poses. The protruding end of the sample shall be waterlofed with a thin coating of end-cap material (see Fig. 1).
Energize the impedance bridge and measure the series capacitance, Cc of the lower end cap.
7.4 Initial Coating Capacitance--Add additional electro lyte to the immersion cell until its level reaches the lower edge of the upper end cap. Immediately measure and record the initial series capacitance, C0, and dissipation factor, DF, of the specimen,
8. Procedure
8.1 Energize each specimen by connecting it to the negative side of the voltage source. Keep each sample energized and immersed to the lower edge of the upper end cap for the duration of the test period. Maintain the specified electrolyte level through regular additions of tap water.
8.2 Throughout the test make periodic measurements of the series capacitance and dissipation factor ofthe immersed specimens in the following mariner:
8.2.1 Temporarily disconnect the test specimen from the voltage source. Verify that the electrolyte is at the proper level within the immersion cell. Connect the measuring bridge between the test specimen and stainless-steel anode. Energize the bridge and measure the series capacitance, C, and dissipation faction, DF, of the test specimen.
8.2.2 Using the observed value of series capacitance, Cs, calculate the- apparent depth of water penetration by the method described in 9.2.
8.2.3 Repeat the measurements of series capacitance and specimen dissipation factor at periodic intervals throughout the duration of the test. The frequency of measurement will depend upon the rate of deterioration of the coating sample. Where the water penetration process is relatively rapid, daily readings of sample capacitance and dissipation factor will be required. Normally, readings made at weekly intervals will adequately define the penetration rate.
N' 5--Some coatings exhibit an initial rise in capacitance and
dissipation factor, but reach a state of equilibrium in 6 to 9 months. An increase in capacitance and dissipation factor following this period of equilibrium, (or failure to reach equilibrium) indicates impending failure. A sample can be considered to have failed when the dissipation factor reaches a value of 1.0.
9. Calculations
9.1 Dielectric Constant--Calculate the dielectric constant, K0, for the coating film as follows:
(C0 - Cr) In I(2tf! + d)/d] 0 NL

Fill the container Ith the electrolyte until it just covers the lower end cap.*

11. Precision
11.1 Due to the range of coating formulations, thick nesses, densities, etc., found among commercially available coated pipe samples; the overall accuracy and reproducibility of the test results by these methods will tend to be poorer than those expected on insulating material of a more uniform nature.
11.2 The precision (reproducibility) of the dissipation factor and depth of penetration by these methods in general is considered to be such that when two tests are performed consecutively on the same specimen under identical condi tions, the difference between the two results may normally be expected nor to exceed 5 % of their mean.

I[2.1 ASTM Standards: ]5G6 Test Method' for Abrasion Resistance of Pipeline I Coatings2 j*G 12 Test Method for Nondestructive Measurement of Film Thickness of Pipeline Coatings on Steel3
Summary of Method
3.1 The method consists of bending a 33.4-mm (1-in. ffeminal) diameter specimen of coated pipe around a manTlel to produce a range of short-radius bends. Coating failure
the form of cracking or I6ss of adhesion is detected |rough visual and electrical inspection of the bent specimen.
Significance and Use
: 4.1 This test will provide information on the ability of Ipatings applied to pipe to resist cracking, disbonding, or Jther mechanical damage as a result of bending. Because the gist is applied to coated pipe from commercial production, fie results can be directly used in the selection of similar haterials for service. The test also has application as a |uality control method when variations in coating applica tion or material formulation will affect bending performfnce.
Apparatus
5.1 The bending apparatus shall be essentially as shown in rigs. 1 to 3 and shall include the following:
5.1.1 Variable-Radius Mandrel constructed from four |l9-mm (0.75-in.) thick pieces of plywood, bolted together
ind conforming to the geometric shape shown in Fig. 1. The

2 Annual Book ofASTM Standards, Vols 06.01 and 14.02.
geometric construction is accomplished by laying out along the outer edge of the mandrel a series of seven consecutive arcs at decreasing radii of 610, 530, 460, 380, 300, and 230 mm (24,21, 18, 15, 12, and 9 in.). The first five arcs shall be carried through a 45-deg angle to the next point of tangency. A 45-deg V-notch shall be cut into the edge of the mandrel for seating the pipe specimen. Holes shall be drilled at appropriate locations in the mandrel face for positioning the lever arm and fastening pipe clamps.
5.1.2 Lever Arm-Roller Assembly--A 1.83-rn (72-in.) lever arm with nylpn roller supplies the mechanical advan tage necessary to bend the pipe specimen. The lever arm shall contain a series of holes which are used to maintain proper clearance between the roller and pipe sample during the bending operation.
5.2 Thickness Gage--Measurements of coating thickness will be required for this test. This shall be done in accordance with Method G 12.
5.3 Holiday Detector--A low-voltage d-c holiday detector of the wet-sponge type, specified in Method G 6, shall be used to locate breaks in the coating film.
6. Test Specimens
6.1 The test specimen should be 2.5 m (100 in.) in length. It should be representative of production-coated pipe and be free of obvious coating flaws or defects. Coating specimens shall be apiplied to 33.4-mm (1-in. nominal) diameter pipe.
7. Conditioning
7.1 The specimen shall be exposed to room temperature for a sufficient time to ensure thermal equilibrium in the pipe and coating. A temperature in the range from 20 to 30C (68 to 85F) shall be considered room temperature.
8. Procedure
8.! Perform the test at a room temperature of 21 to 25C (70 to 77F).
8.2 Measure the applied coating thickness of each spec imen in accordance with Test Method G 12.
8.3 Place the conditioned test specimen into the V-notch. Secure the pipe in place with clamp No. 1 and tighten the thumb screw. Remove the threaded handle from clamp No. 1 to allow for clearance of the lever arm. With the steel pivot pin at hole A of the lever arm (see Fig. 3), insert the pin into the socket on the bed of the bending jig. Place the nylon roller at position C on the lever arm. Apply the roller to the pipe specimen, and with a constant, even force with the lever handle, bend the pipe aound the mandrel until the 460-mm (18-in.) radius bend has been made. Insert and secure pipe damp No. 2. Continue bending the pipe until the 300-mm (12-in.) radius has been reached. Insert and secure pipe

clamp No, 3. Reposition the lever arm by moving the pivot pin to the 25-mm (1-in.) diameter hole in the mandrel surface. Move the nylon roller to position B on the lever arm. Apply the roller to the pipe and complete the bending operation by forming the specimen through the 230-mm (9-in.) radius.
8.4 Examine the bent specimen wth a wet-sponge holiday detector to determine at what point, if any, cracking of the coating film occurred. Note the number, size, location, and type of cracks present. Examine the pipe specimen for any loss of coating bond caused by the bending operation.
N' 1--The possibility of some coatings developing stress-induced
cracks in the period following the bending operation should not be overlooked. If this is a consideration, the bent specimen should be retained for a 24-h post-bent inspection.
9. Report
9.1 The initial test report shall include the following: 9.1.1 Complete identification of the coated pipe tested, including: name and type of coating, average coating thick ness, minimum coat.ing thickness, maximum coating thick ness, manufacturer's Ipt number, and date of manufacture. 9.1.2 Temperature of the pipe specimen as tested, 9.1.3 Radius at which cracking first'Occurred, , 9.1.4 Description ofthe type of cracking, 9.1.5 Location and extent of any loss in pipe-to-coating bond, 9.1.6 Number of specimens tested, 9.1.7 Any peculiar characteristics of the specimen noted during the test or after immediate removal from the test apparatus, and 9.1.8 Post-bend retention time.

original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.! This test method is intended to define conditions for the exposure of coated pipe to weather.
1.2 This test method specifies qualifications for the sam
ples, procedure to be followed in exposure to weather and procedure for evaluating effects of exposure including visual examination and other tests.
1.3 This test method may involve hazardous operations and equipment. This test method does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this test method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.4 The values stated in SI units to three significant decimals are to be regarded as the standard.
the longer the exposure period, the more reliable are ih results obtained.
4. Summary of Test Method
4.1 The effects of outdoor weathering on pipeline coating after 6,12, and 24 months' exposure are determined visual! t and by electrical means by comparing exposed samples ot coated pipe with unexposed samples of coated pipe befo.j and after impact and bending tests. At the beginning of Hi test the starting^ samples are qualified by a cathodic disbonding test.
p. Location of Test Sites ,
5.1 Weathering racks shall be located in cleared ana-, representative of local outdoor weather Conditions.

3. Significance and Use
3.1 Since coated pipe may be stored outdoors for long periods before burial, weathering tests of the type described in this test method are needed to evaluate the stability of these coatings stored outdoors. The results obtained should be treated only as indicating the general effect of weathering. Exposure conditions vary greatly from year to year, from one part of a year to another, and from locality to locality. The results of short-term exposure tests in the north are more meaningful if exposure is started in the summer followed by . a winter season. In southern areas where climatic conditions are more uniform throughout the year, the time of year when short-term exposure is started is less critical. In all localities,

Summary of Test Method
r 2.1 The coating thickness is determined by an instrument Jjhat measures thickness by nondestructive techniques, based ISm variations in magnetic flux or magnetic attraction be tween its detection unit and the magnetic base material.
. Significance and Use
3.1 Measurements of film thickness are an essential part gbfmost ASTM test methods related to coatings on steel pipe, j&dequate thickness is important for a coating to fulfill its Junction of preventing or mitigating corrosion of steel (pipelines.
3.2 The accuracy of the thickness measurements may be ^influenced by the deformability of the coating. This test
aethod is not applicable to coatings that would be readily peformable under the force exerted by the probe of the
neasuring instrument.
|4, Apparatus
4.1 The apparatus shall be a nondestructive-type thickBness gage capable of being standardized over its range of intended use. It shall be designed so that variations in fmagnetic flux or magnetic attraction between its detection (unit and the steel base can be calibrated to indicate the thickness of the coating material.
4.2 It shall be suitable for measuring thicknesses of dry, 1 nonmagnetic coatings on either a flat or a circular base.
1 This test method is under the jurisdiction of ASTM Committee G-3 on \ Durability of Nonmetallic Materials and is the direct responsibility of Subcom| mittee G3.06 on Durability of Pipeline Coatings and Linings.
Current edition approved June 24, 1983. Published August 1983. Originally published as O 12 -69 T. Last previous edition G 12 - 77.
5. Standardization of Instruments
5.1 The instrument shall be standardized m accordance with the manufacturer's instructions before use by em ploying suitable thickness standards. The standardization shall be checked at frequent intervals during use.
5.2 Nonmagnetic standards of uniform thickness are available in either of two types, foil or coated substrate, as supplied or recommended by the manufacturer of the instrument.
5.2.1 Foils (Shims)--The thickness ofthe foil should be as close as possible to the expected thickness ofthe coating to be measured. The foil should be placed on a smooth, clean, low-carbon, steel plate, making certain that there is intimate contact between the foil and the substrate. 'It is recoriimended that single foils of proper thickness be used and that foils be replaced frequently, since they are subject to inden tation. Foils are advantageous for standardizing oh curved surfaces and are often more readily available than coated standards.
N' 1--For some instruments there is an effective depth of
penetration of the field created by the instrument probe. This is the critical depth of thickness at which the instrument wili no longer be affected by increases of substrate thickness. Since it depends on the instrument and substrate, it should be determined experimentally.
5.2.2 Coated Substrate Standards2--These standards con sist of nonmagnetic coatings of known thickness perma nently bonded to a iow-carbon steel (1010 grade) substrate, 8 mm (0.30 in.) thick. The thickness standard should be as close as possible to the expected thickness ofthe coating to be measured.
N' 2--If the curvature of the coating to be measured is sufficient
to preclude standardization on a flat surface, the standardization should be done with a standard foil on a substrate with the same curvature as the coating to be measured.
6. Procedure
6.1 Operate each instrument in accordance with manufacturer's instructions.
6.2 Take a minimum of twelve readings per piece of pipe as follows: Take three equally spaced readings along the top surface; rotate the pipe 90 three times, taking three equally

spaced readings after each rotation. Record the average, minimum, and maximum of the twelve readings as the coating thickness.
N' 3--Instruments with two contact poles shall be positioned on
the coating surface with the poles in the same plane.
N' 4--The anchor pattern of the steel pipe substrate must be
considered for its effect on the accuracy of the measurements if the anchor pattern is greater than '25 % of-the coatihg thickness.
N' 5--Foreign materials such as dirt and grease shall be removed
by suitable cleaning without removing any coating materials.
N' 6--Measuring instruments and methods may depend on the
technique of the operator. For example, the pressure applied to a probe and the rate of applyitiga balancing force to a magnet will vary from one individual to another. Often such differences can be reduced or eliminated either by having the gage calibrated by the same operator who will make the measurement or by using constant-pressure probes. Probes must be positioned perpendicular to the surface of the specimen at the point of measurement. Some magnetic ipstrunjents of the magnetic-attraction type require the pole piece to be in a vertical position. If a magnetic instrument is to.'be used in a horizontal or upside-down position, its calibration for that position should'be verified.
N' 7--Instruments using magnetic attraction are sensitive to the
speed with which the magnet is removed from the specimen. The magnet must be removed so. that thickness measurements are not affected by speed of removal.
7. Report
7.1 The report shall include the following:
7.1.1 Complete identification of the specimen including-
name and code number of the coating; pipe diameter-
source; production data, including surface preparation o-'t'h -
substrate and depth of anchor pattern, if known; mj
production run number.
7.1.2 Name and type of instrument used, and method of standardization, and
7.1.3 Number of thickness measurements taken, and the
average, minimum, and maximum value of the measure
ments.
.. . .'
8. Precision-
8.1 The repeatability and reproducibility of thickness measurements wili depend on thb instrument design, the operator,1 and the particular measuring application.
8.1.1 Repeatability--When the same instrument is used by the same operator, duplicate measurements on the Same sample should agree with each other within 5 %.
8.1.2 Reproducibility--Separate operators using different instruments on a known thickness standard should obtain average results agreeing with' each other within 10 % of the thickness standard.

significance and Use
4.1 This'test Is intended to simulate the effects of ackfilling after pipe has been placed in the trench. The ackfill is often rocky soil and, if it is unscreened and the oated pipe is unshielded by sand or other protective adding, the falling rocks may seriously damage the coating.
. Apparatus
5.1 The impact apparatus shall be essentially as shown in rig, 1 and shall include the following:
5.1.1 Box with Chute, providing a means of dropping
6.1 Test specimens shall be 600 mm (24 in.) Icing and shall be cut from a representative piece of coated pipe. Only holiday-free specimens shall be used in the test.
7. Procedure
7.1 Perform the test at a room temperature of 21 to 25"C (70 to 77F).
.7.2 The procedure consists of dropping up to 10 buckets of stones on coated specimens. The number of buckets of stones required represents the resistance of the coating to this type of impact.
7.3 Place the test.specimen in the trough below the chute.

7.4 After each drop, remove the specimen. Examine the specimen visually for breaks in the coating. If there are ho visual breaks, check with the holiday detector appropriate for the coating thickness for holidays in the coating. If there is no visual or electrical evidence of holidays, repeat the test until the first holiday is detected and record the number of drops and the number of holidays detected. In repeating the test, the specimen should be replaced in the trough so that the same portion of the coated surface is always subjected to the falling stones. After the Same stones have been used five times, they should be replaced.

3.1
This test method uses a falling fixed weight having a
fipecified diameter impact surface, tup, which is restrained
Vertically and dropped from varying heights to produce
i'jmpaet energies over the required range. Electrical inspection Is used to detect resultant breaks in the coating. Impact
resistance is determined as the amount of energy required to Irause penetration of the coating film.
p. Significance and Use
j 4.1 The ability of a pipe coating to resist mechanical ^damage during shipping, handling, and installation will '(depend upon its impact resistance. This test method provides
a systematic means for screening coating materials with regard to this property.
5. Apparatus
5.1 This test method can be successfully used with impact apparatus conforming to the following specifications:
1 This test method is under the jurisdiction of ASTM Committee G-3 on Durability of Nonmetallic Materials and is the direct responsibility of Subcom* mittee G03.06 on Durability of Pipeline Coatings and Linings.

3 Annua! Book ofASTM Standards, Vol 14.02. 4 Available from Society of Automotive Engineers, 400 Commonwealth Drive, Warrendale, PA 15096.
5.1.1 Tup--The tup shall be made up from a tup body and a tup nose having a combined, fixed weight of 1.361 kg (3.00 lb) and shall be used over a drop range of 0.61 to 1.22 m.(2 to 4 ft). With most coatings, a 1.361-kg (3.00-lb) tup dropped through a distance of 914 mm (3 ft) yields suitable results. The tup nose shall have a 15.875-mm (Vs-in.) hemispherical head.
N' 1 --Frequent replacement of the tup nose can be avoided if it is
cut from steel capable of being hardened to a hardness of Rockwell C/45 while retaining an impact toughness of at least 15 ft-lb (20.34 J). Ball bearings conforming to SAE Grade 52100 have also been found suitable for this purpose.
5.1.2 Drop Tube--A tube 1.52 m (5 ft) long shall be used to contain the tup and guide it during free fall The drop tube shall be constructed of steel, aluminum, or any other suitably rigid material and internally sized to provide a minimum of friction to the falling tup. A scale shall be attached for measuring the height of drop to the nearest 2.54 mm (0.10 in.).
5.1.3 Specimen Holder--The base plate of the apparatus shall include a device for positioning and holding the pipe specimen on line with the axis of the vertical drop tube.
N' 2--An arrangement using a V-notch vise made .of metal with
spring clamp is recommended for this purpose. Glancing blows, caused by an out-of-plumb condition between drop tube and pipe sample, will cause erratic test results.
5.1.4 Apparatus Support---Both the apparatus and sample shall be firmly supported and secured to a rigid base to optimize energy transfer from the tup to the specimen.
5.2 A design for the test apparatus appears in'Figs. Xl.l through X 1.3 of Appendix XI.
5.3 Thickness Gage--Measurements of coating- thickness will be required for this test, and shall be done in accordance with Method G 12.
5.4 Holiday Detector--A suitable detector as specified in Test Methods G 62 shall be used to locate breaks in the coating film.
6. Test Specimen
6.1 The test specimen shall be a 406.4 mm (16 in.) long piece of Schedule 40, 60.325 mm (2.375 in.) outside diam eter coated pipe prepared with its surface preparation and coating procedures equivalent to that of production coated pipe.
6.2 Seven specimens shall be required for the test.
7. Conditioning
7.1 The specimen shall be exposed to a room temperature of 21 to 25C (70 to 77F) for a period of 24 h before beginning the test.
1043
DUP050298221
# G 14
8. Preliminary Measurements
8.1 Measure the applied coating thickness of each spec imen in accordance with Test Method G 12.
8.2 Place test specimen in sample holder and lightly place tup on surface of the coating. Adjust either the drop tube or the attached scale so that the wing bolt (lifting pin) is at the zero mark of the scale.
8.3 Make a preliminary set of impact readings to deter mine the approximate starting point for the test. This shall be done by strildng the first specimen from a height sufficient to cause failure of the coating film. Consider any penetration a failure if it is detectable with a suitable Holiday Detector as specified in Test Methods G 62.
'8.3.1 Reduce the height by 50% and make a second exploratory drop at a fresh area on the pipe surface. Continue testing in this manner, with the corresponding reduction in height between drops, until the coating fails to break.
No t ' 3--Choose test locations at the specimen surface in a random manner and keep at least a 76.2-mm (3-in.) distance between adjacent points of impact and within 38 mm f 1 Vi] in.) from the ends. Choosing test points in any regular pattern will bias the experiment and introduce error into the test results.
8.3.2 Repeat the test at the height immediately preceding the occurrence of the nonfailure to determine if an approxi mate level for the mean impact strength has been bracketed. Two successive reversals of coating performance between failure and nonfailure will give sufficient indication that the point has been reached.
9. Procedure
9.1 Perform the test at a room temperature of 21 to 25C (70 to 77F).
9.2 Begin testing from the approximate height determined in 8.2 and corresponding to the point at which the first nonfailure was registered. Maintain a fixed increment be tween adjacent testing heights.
9.3 Use a suitable detector, as specified in Test Method G 6, to determine penetration or lack thereof of the coating after ea'ch individual impact.
9.4 If the coating film is penetrated on the initial drop, make the next test at the next lower height increment. If the first specimen does not fail, make the second test at the next higher increment.
9.5 In a similar manner, determine the height of fall by the performance of the coating on each preceding drop. Maintain a constant height increment between readings. Continue to apply this "up-and-down" method4 until 20 successive impact readings have been made.
4 This system of testing, nomenclature, and calculation is described by Dixon, W, J. and Mood, A. M., nA Method for Obtaining and Analyzing Sensitivity Data," Journal Am. Statistical Assn., JSTNA, Voi 43, March, 1948, p. 309.
10. Calculation
10.1 Calculate the mean value of impact strength, m, in g/cm (or in./lb) as follows:
where: ha = minimum height at which the less frequent event
occurs, cm (or in.), d = increment in height of drop, cm (or in.), A = sum of the frequency of occurrence at each height
increment times the number of increments above the k0 value for each observation itrthe N total, N = total number of the less frequent- event (coating failures or nonfailures), and W = tup weight, g (or lb).
NOTE 4--The minus sign is used when the calculation of the mean is based on the total number ofcoating failures and the plus sign when it is based on the nonfailures.
10.2 Calculate the sample standard deviation, s, in gramcentimetres (or inch-pounds) as follows:
5 = 1.620 dW+ cj
where:
C = 0.737 when d is in cm, or 0.029 when d is in in., d, N, A, and W are as defined in 10.1, and B = sum of the frequency of occurrence at each height
increment times the square of the number of incre ments above the h0 value for each observation in the N total.
N' 5--Adequate definition of coating impact strength will result only if the height increment, d, has been properly chosen. When testing
polymeric films in the range front 0.254 to 1.016 mm (0.010 to 0.040
in.), height increments of from 5.1 to 12.7 mm (0.2 to 0.5 in.) have been
found suitable with the 1.361-kg (3.0-lb) tup. Larger increments may be
necessary for thicker materials. If after making tfre calculations of 10.1 and 10.2, the ratio of the height increment to the standard deviation
(d/s) is less than 0.20, the test should be repeated using a larger value for the increment d. This procedure will result in an improved estimate of the coating impact strength.
10.3 An illustration of the use of these equations appears
in Appendix X2.

Designation: G 17 - 88
Standard Test Method for Penetration Resistance of Pipeline Coatings (Blunt Rod)1
This standard is issued under the fixed designation G 17; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year oflast revision. A number in parentheses indicates the year of last reapprovai. A superscript epsilon (0 indicates an editorial change since the last revision or reapprovai.
1. Scope
1.1 This accelerated test method is used to determine the relative resistance of steel pipeline coatings to penetration or deformation by a blunt rod under a specified load. The test method is intended to apply to the testing of all types of nonmetallic pipeline coatings subjected to various tempera tures.
1.2 This test method may involve hazardous operations and equipment. This test method does not purport to address all of tfte safety problems associated with its use. It is the responsibility of the user of this test method to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.
1.3 The values stated in SI units to three significant decimals are to be regarded as the standard.
2. Summary of Test Method
2.1 The depth or rate of penetration or deformation that is caused by a weighted blunt rod to a coating system applied to steel pipe is measured over a period of time with a micrometer depth gage. Three consecutive identical readings taken at specified intervals conclude the test.
3. Significance and Use 3.1 Since pipeline coatings are subjected to concentrated

Film Thickness of Pipeline Coatings on Steel2
by f|3. Summary of Test Method
3.1 The test method consists of an immersion test where | coated pipe specimens, each containing a simulated joint, | tee, or patched area, are suspended in an electrolyte and placed under cathodic protection by connecting the speci
mens to-the negative (--) terminal of a 6-V d-c power supply (see Fig. 1). An anode, also immersed in the electrolyte and connected to the positive (+) terminal of the power supply, completes the test circuit. Joint or patch performance is followed through periodic determinations of leakage current measured as voltage drops across a calibrated resistor in the i anode-to-cathode circuit.
3.2 Capacitance and dissipation factor measurements are used to supplement the periodic leakage current determina tions.
4. Significance and Use

damaged areas in an otherwise coated pipeline will be subjected to corrosion if allowed to come in contact with the soil environment. The performance of joint and patching materials designed to function as protective coverings will depend upon such factors as the ability of the material to bond to both the pipe coating and exposed metal surfaces, the integrity of the moisture seal at lapped joints, and the water absorption characteristics of the joint material.
4.2 The existence of substantial leakage current through the coating joint, patch, or fitting is reliable evidence that the material has suffered a significant decrease in its perform ance as a protective barrier. In a similar manner, measured changes in joint capacitance and dissipation factor are useful because they are related to the water absorption rate of the joint material. Water permeating an insulating barrier in creases its capacitance and its progress can be measured through the use of a suitable impedance bridge.
S. Apparatus
5.1 Test Vessel, nonconducting, shall be used to contain the test specimens. Dimensions of the vessel shall permit the followihg requirements:
5.1.1 The test vessel shall be large enough to allow for suspension of the specimens in a vertical position and equidistant from a centrally located anode. The specimens shall not touch either each other, the walls, or bottom of the test vessel.
5.1.2 The test vessel shall be deep enough to allow for immersion of the specimens in th'e electrolyte to the lower edge of the upper moisture shield (see Fig. 2).
N' l--A commercially available, 42 L (11-gal) waste container of
high-density polyethylene can be conveniently used as a test-vessel and will accommodate up to sue test specimens of a size indicated in 7.2.
5.2 Support Plate, fabricated from a nonconductive mate rial, to suspend the specimens in the test vessel. The support plate shall contain an access hole for the reference electrode. A typical test cell is illustrated in Fig. 3.
5.3 Anode, fabricated from 9.525 mm (0.375-in.) diam eter 300 series stainless steel rod, 609.6 mm (24.00 in.) long. Other inert anodes such as carbon or platinum may be used.
5.4 D-C Voltmeter, to serve the dual purpose of (/) mea suring leakage current as a potential drop across a 1,000-9 shunt in the measuring circuit and (2) measuring the potential of the test specimen with reference to a Cu-CuS04 half cell. The instrument characteristics for these functions shall be:
5.4.1 Voltage Range--50 pV full scale to 10 V full scale in overlapping 1 x and 3x ranges.
5.4.2 Accuracy--3 percent of full scale on all ranges. 5.4.3 Input Resistance--Greater than 10 M9 on all ranges.

5.11 Connectors--Miniature, pin-type, insulated jacks
shall be used at the point of connection to each test
specimen. The jacks serve two important functions: (/) they
permit the disconnection of the specimen from the voltage
source when the impedance bridge is in use, and (2)
disconnection of the specimen from the test circuit also
removes the effect of stray capacitance due to excessive lead
length that may introduce error into impedance bridge
measurements.
5.12 Foil Shield--As an additional safeguard against stray
capacitance effects, wrap the entire test vessel in heavy-gage
aluminum foil as shown in Fig. 3 and ground the shield.
FIG. 1 Test Circuits
5.5 Thickness Gage--Measurements of coating thickness will be required for this test. Any instrument suitable for use with Test Method G 122 can be used. However, the choice of measuring gage shall be compatible with the joint coating thickness that will be encountered in the test.
5.6 Ohmmeter--Measurements for end-cap integrity shall be made with a suitable ohmmeter capable of reading resistance to an upper,limit of 1000 MQ .5 %.
5.7 Reference Electrode--A Cu-CuS04 half cell of con ventional glass or plastic tube with porous plug construction, but preferably not over 19.05 mm (% in.) in diameter, having a potential of --0.316 V with respect to the standard hydrogen electrode.
N' 2--A saturated calomel half cell may be used, but measure
ments made with it shall be converted to the Cu-CiiSO, reference for reporting by adding -Q.072 V to the observed reading. :
5.8 Voltage Source--A battery or rectifier-type power supply shall be used to maintain a potential difference of 6.0 0.1 V dc between each of the test specimens and the Cu-CuS04 half cell. Where multiple specimens are tested, a suitable voltage-dividing circuit will be required for indi vidual control of the voltage applied to each specimen.
5.9 Circuit Wiring from the anode to specimen shall be of No. 18 Awg insulated copper. A switch for disconnecting each specimen from its voltage source shall be included in the circuit. A 1000 1 percent, 1-W (minimum) precision resistor shall be placed in the anode-to-cathodc circuit as a shunt for current. A diagram illustrating the test cell wiring appears as Fig. 1.
5.10 Capacitance Bridge--Measurements of specimen ca pacitance and dissipation factor shall be made with a low-voltage a-c, resistive ratio arm-type bridge3 having the following characteristics:
5.10.1 Oscillator Frequency, 1 kHz 2 % tolerance.
3 Instruments found to meet these requirements arc the General Radio Type 1650-B Impedance Bridge and the Heath Co, Model IB-28 Impedance Bridge (Kit).
6. Materials
6.1 Electrolyte--The electrolyte shall consist of potable tap water with the^ddition of 3 weight percent of technicalgrade sodium chloride.
6.2 Materials for sealing the ends of the specimens may consist of waxes, epoxies,,or other suitable materials. How ever, they should have a dielectric constant in the range from 2 to 6, and exhibit a low water-absorption rate. It is also important that the end-cap material maintains good adhe sion to any coated pipe surfaces throughout the test period.
7. Test Specimen
7.1 The joint specimen shall be prepared from a represen tative piece of 60.325 mm (2.375 in.) outside diameter, Schedule 40, production-coated pipe.
7.2 Each piece of coated pipe shall be 381 mm (15.0 in.) long and serve as a carrier for the particular joint material to be tested.
7.3 The simulated coatingjoint shall be made by cleaning away a 101.6 mm (4.0-in.) band of pipe coating starting from a point 203.2 mm (8.0 in.) below the upper end of the pipe. The coating may be removed by power brushing or any other suitable device that will remove all of the coating in the area indicated and leave a dean metal surface behind.
7.4 The lower end of the test specimen shall be plugged flush with a stopper and sealed or capped with a material meeting the requirements of 6.2.
7.5 When used, the primer shall be applied to the test specimen in sufficient quantity to coat the test specimen from a point 88.9 mm (3.50 in.) below its upper end and ending at a point 317.5 mm (12.5 in.) from the upper end. This will allow for a 12.7-mm (0.5-in.) band of excess primer beyond each tape margin.
7.6 The joint material to be tested shall be applied to the prepared pipe specimen (using a spiral wrap for tapes) and starting from a point 101.6 mm (4.0 in.) below the upper end of the pipe section and ending at a point 304.8 mm (12.0 in.) from the upper end. The 203.2 mm (8.0 in.) ofjoint material thus applied should overlap the bared section of pipe by 50.8 mm (2.0 in.) at each end. This distance represents the typical cut-back distance encountered in the field joining, through welding, of coated pipe in 60.325 mm (2.375 in.) outside diameter size. A diagram of the joint specimen appears as Fig. 2.

iyer damaged areas on coated pipelines can be tested using the same procedures, with the patching compound applied, instead, to the bared ftea of the simulated joint.
7.8 The upper 76.2 mm (3.0 in.) of the completed joint lest specimen shall be coated with the material used for the power end cap. This moisture shield can be conveniently
hade, in the case of some waxes and epoxies, with several |uccessive brush or dip-applied applications. The thickness ijf the moisture shield should be approximately 3.175 mm |p. 125 in.).
. Testing Temperature
8.1 Perform all tests at a room temperature of 21 to 25"C 70 to 77*F).
. Preliminary Test Measurements 9.1 Coating and Joint Thickness--Measure and record he thickness of the base coating which lies exposed at each end of the test joint. Measurements shall be made in Accordance with Method G 12. In a like manner, measure and record the average thickness of the joint covering. 110. Procedure for Leakage Current Measurements 10.1 Suspend the joint test specimens in the test vessel, ^observing the clearances specified in 5.1.1 and 5.1.2. Fill the jjvessel with electrolyte, bringing the fluid level up to a point tmidway between the end cap and the lower edge of the joint Itnaterial. 10.2 Connect one terminal of the ohmmeter to the test I'specimen and the other terminal to the central anode. The
N' --Alt dimensions are in millimetres with inches in parentheses.
FIG. 2 Joint Test Specimen
anode should be in contact with the electrolyte. Measure the
apparent sample-to-anode resistance in ohms. The reading shall remain above 1000 MQ for 15 min. Readings below this value probably indicates a faulty end-cap seal which should be repaired before the joint specimen is totally immersed.
10.3 Totally immerse the joint test specimens up to the lower edge of the moisture shield. This level shall be maintained throughout the test period by regular additions of tap water. The test shall be performed at room tempera ture.
10.4 Connect each joint test specimen in series with a 1000-0 1 % (1-Wj resistor, a suitable switch, and the negative (--) terminal of the voltage source.
10.5 Connect the central stainless steel anode to the positive (+) terminal of the voltage source.
10.6 Energize the voltage source. Adjust the voltage to each specimen by connecting a voltmeter between each
sample and the Cu-CuS04 half cell and varying the- voltage output until 6,0 V are measured between sample and half cell (see Fig. 1).
10.7 As soon as the circuit is energized and voltage adjusted to each joint test specimen, measure and record the voltage across each 1000-fi shunt resistor.
10.8 Measure and record the closed circuit potential, EB, and open circuit potential, E0, of each joint specimen with reference to the saturated Cu-CuS04 half cell.
N' 4--Any drop in closed circn t potential (B) of a joint
specimen greater than 20 % of the terminal voltage (,) probably indicates a developing current leak in the joint area. In a like manner, any open circuit potential (EJ greater than 0.05 V may indicate the presence of a developing conductive path across the test joint. (Both voltages are referenced to the Cu-CuS04 half cell.)
10.9 Using the d-c voltmeter in 5.4 measure and record the voltage appearing across the terminals of the voltage supply.
10.10 Continue, on a periodic basis, the measurements specified in 10.7 through 10.9. Calculate the apparent joint

resistance by the method described in 12,1. 10.11 Prior to removal, reexamine a suspected joint
failure to confirm that any observed drop in joint resistance is not due to a faulty end-cap seal. This can best be accomplished by removing the specimen from the test cell and allowing it to dry. When dry, reimmerse it to just above the level of the: lower end cap and check the integrity of the cap by the method outlined in Section 8.
11. Procedure for Measurement of Capacitance and Dissipa tion Factor
11.1 The series capacitance and dissipation factor be tween each joint sample and the central stainless-steel anode shall also be measured. These measurements shall be made at the time of initial immersion and continued on an identical schedule with the voltage readings. They shall be made in the following manner:
11.2 Temporarily disconnect the test specimen from the voltage source. Connect the impedance bridge between the test specimen and stainless-steel anode. Energize the bridge and measure the equivalent series capacitance, C, and dissipation factor, DF, or the test specimen using a "null" technique to balance the measuring bridge.
11.3 A continued rise in joint capacitance and dissipation factor from the values recorded at the time of initial immersion, will indicate progressive absorption of water by the joint material.
11.4 The joint test shall continue for 180 days or until the joint resistance falls to a value of4600 Q for 1 m2 (50 000 Q for 1 ft2) of immersed joint surface.
12. Calculations
12.1 Joint Resistance--Calculate the resistance, Rjt for the joint sample as follows:
Rj = 1000 Al(ED - Ej/AJ
where - resistance, fl/cm2 (D/ft2),
A immersed sample area (excluding end cap), cm2 (ft2), Eb closed circuit potential of sample (reference Cu-
CuS04), V (switch closed), Ea open circuit potential of sample (reference Cu-
CuS04), V (switch open), and EF voltage across I000-R shunt resistor, V, (switch
closed).
13. Report
13.1 All test reports shall include the following: 13.1.1 Complete identification of the joint specimen in cluding: 13.1.1.1 Name and code number of the base coating.
13.1.1.2 Thickness of the base coating,
13.1.1.3 Name and code number of the joint material including type (that is tape, two-part mix, etc.),
13.1.1.4 Method of application of joint material, in cluding amount of overlap.
13.1.1.5 Where applicable, the width and thickness of the joint material (tapes),
13.1.1.6 Where applicable, the name, code number, and type of primer,
13.1.1.7 Where applicable, the method of application of primer,,
13.1.1.8 Average thickness of the joint material, as ap
plied, and
. 'i
13.1.1.9 Dates of starting and terminating the test and other information that may be pertinent.
13.2 The following readings shall be recorded on a peri odic basis:
13.2.1 Voltage across the 1000-0 shunt resistor, E%, 13.2.2 Closed-circuit potential of the joint specimen refer enced'to the Cu-CuS04 half cell, EB,
13.2.3 Open-circuit potential of the joint specimen refer enced to the Cu-CuS04 half cell, Ea,
13.2.4 Terminal voltage at the power supply, and
13.2.5 Calculated value ofjoint resistance,
13.2.6 Initial series capacitance of the joint sample, and `
13.2.7 Initial dissipation factor of the joint sample.
N' 5--The frequency of experimental readings will depend upon
the performance of each joint specimen. Specimens that show a high rate ofchange may require more frequent watching if the point of failure is to be recorded. Normally, weekly readings have been found to be adequate. Joint performance can be conveniently followed.through plots of Joint Resistance versus Time and Dissipation Factor versus Time in semilogarithmic coordinates, and Capacitance Change versus Time in rectangular coordinates.
14. Precision
14.1 Due to the range of joint coating formulations, thicknesses, densities, etc. found among commercially avail able materials, the over-all accuracy and reproducibility of test results by these methods will tend to be poorer than those expected on straight runs of coated pipe. The fact that most joint materials are hand-applied introduces an inherent factor of variability into the test results. The basic purpose of these methods is to provide a means for the comparative screening of combinations of joint materials and base coatings for insulating effectiveness.
14.2 The precision (reproducibility) of the joint resistance determination by these methods is considered to be such that when two tests are performed consecutively on the same specimen and under identical conditions of application, the difference between the two results may normally be expected not to exceed 10 % of their mean.

3.1 Apparatus and materials are described whereby proitective coatings on steel pipe are subjected to disbonding by Ian electrical stress. Specimens with intentionally damaged lareas are buried in soil at an outdoor site and electrically jconnected to a magnesium anode. After test, the disbonded fcoating is removed, the exposed area measured, and comparfisons are made to other specimens similarly exposed.
j 4. Significance and Use
4.1 Coated pipe is seldom, if ever, buried without some 1 damage to the coating. Hence, an actual soil-burial test can | contribute significant data, provided the method of testing is

1 3. Significance and Use
,,r 3.1 Several types of apparatus with different exposure { ^conditions are available for use. No single operating proce
dure for light exposure apparatus with or without water can i'be specified as a direct simulation of natural exposure. This
'practice does not imply expressly or otherwise an accelerated jweathering test. i | 3.2 Since natural environments vary with respect to
[geography, topography, and different exposure periods, it | may be expected that the effects of natural exposure will vary [accordingly. Furthermore, all materials are not affected [equally by the same environment. Therefore, results ob tained by use of this practice should not be represented as `equivalent to those of any natural weathering test until the [degree ofquantitative correlation has been empirically estab lished for the material in question.
3.3 Variations in results may be expected among instru ments of different types and when operating conditions among similar type instruments vary within the accepted limits of this practice. Therefore, no reference should be made to results from use of this practice unless accompanied by the report form as specified in Fig. I.
4. Apparatus13 4.1 The apparatus employed shall use one or two carbon-
arc lamps as the source of radiation, and shall be one of the following types, or equivalent. The term "cycle" is defined as the total time for all exposure conditions (light, light plus water spray, dark periods) that are repeated.
n Available from American National Standards Institute. 1430 Broadway, New York. NY 10017.
13 Available from the Atlas Electric Devices Co., 4114 N. Ravenswood Ave., Chicago, IL. 606132 and from Suga Test Instruments Co., Ltd. 4-14, Shinjuku 5-chome, Shinjuku-ku, Tokyo, 160, Japan.
No t ' 2--Several models of carbon-arc type exposure devices are no longer commercially available and should be considered obsolete. Exposures in these devices are not recommended and should only be
made when mutually agreed upon by all interested parties.
4.1.1 Type D--Twin enclosed carbon-arc lamp apparatus, with a 762 mm (30 in.) diameter specimen drum rotating at 1 rpm, automatic control of temperature and cycle, and manually adjusted humidifier.
4.1.2 Type DH--Same as Type D, except with automatic control of the humidity.
4.1.3 Type E--Single open-flame sunshine carbon-arc lamp apparatus, with a 959 mm (37.75 in.) diameter specimen rack rotating at 1 rpm, automatic control of temperature and cycle, and manually adjusted humidifier.
4.1.4 Type EH--Same as Type E, except with automatic control of the humidity.
4.1.5 Type H--Single enclosed carbon-arc lamp appa ratus, with a 508 mm (20 in.) diameter specimen rack, rotating at 1 rpm, automatic control of temperature and cycle, and manual regulation of the humidity.
4.1.6 Type HH--Same as Type H, except with automatic control of the humidity. ......
4.2 The apparatus should consist of a suitable frame within which is located a test chamber, and necessary com partments for housing control and regulating equipment.
4.3 Provision should be made for mounting or supporting the test specimens in a circular rack or drum that is rotated around the arc or arcs. This provides uniform distribution of , the radiation on all specimens around the circumference of the rack. It does not, however, improve the distribution of the radiation along the vertical axis.
4.4 Adequate ventilation should be provided in the test chamber to prevent contamination of the specimens from combustion products of the arc.
4.5 The apparatus should include equipment necessary for measuring and controlling the following:
4.5.1 Arc current, 4.5.2 Arc voltage, 4.5.3 Black-panel temperature (Note 3),

5.2 Mount the test specimens, except those whose s
or other physical characteristics make it impractical, i
rally both above and below the horizontal center line o! in,..;
source of radiation. To assure that specimens receive thgfj
greatest uniformity of radiant exposure, reposition nicm
vertically in a sequence which will provide each specimen i
equivalent exposure periods in each location. When the \ '
exposure interval does not exceed 24 h, each spec, nn u j
should be located equidistant from the horizontal axis oi ihe
arc. For exposure intervals not exceeding 100 h, daily!
rotation of the specimens is recommended. Other methods )
of achieving uniform total irradiation may be employed ifs \
mutually agreed upon by concerned parties.
I
5.3 For enclosed arcs only, where physical characteristics!t
do not permit suspension ofspecimens iri a vertical position, 1
expose them horizontally on a rack 165 mm (6.5 in.) below !
the horizontal center of the source or sources of radiation. *
Mount the specimens on a circular horizontal rack equipped
with turntables, so that each specimen is rotated on its own
axis as all ofthe specimens are rotated around the source or
sources of radiation.
5.4 Temperature measurement and control should be
based on the black-panel thermometer unit. Support the
panel with the thermometer attached in the specimen drum*
or rack in the same manner as the test specimens so that it
will be subjected to the same influences,
4.5.4 Water-spray pressure, 4.5.5 Operating schedule or cycle, 4.5.6 Exposure time, and 4.5.7 Relative humidity {Types DH, EH, and HH only). 4.6 Types DH, EH, and HH apparatus are equipped with thermostatically actuated vaporizing units for adding mois ture to the air as it passes through the conditioning chamber prior to its entry into the test, chamber. Type H and some
Types D, and E have manually regulated, electrically oper ated vaporizing units. Relative humidity of the air in the test chamber is calculated from the readings of the wet- and dry-bulb thermometers, either indicating or reporting, whose sensing portion is located in the air stream at its point ofexit
from the test chamber. 4.7 The black-panel thermometer unit should consist of a
stainless steel panel 1 by 70 by 150-mm (.060 by 2.75 by 5.875 in.) to which is mechanically fastened a temperature sensing device. This device shall be capable of measuring temperature to a repeatability of 4 1'C (see Figs. 2 and 3). The face of the panel with the temperature sensing device attached should be finished with two coats of baked-on black enamel selected for its resistance to light and water.
4.8 Detailed requirements and operating conditions ofthe apparatus are given in Table 1 and Figs. 4 to 6.

5.4. 1 Program the instrument to operate in a continuous
|!ight-on mode. Fill specimen rack with blanks and the
Iblack-panel thermometer. Operate in this mode while estab-
flishing the black-panel temperature according to the manu- '
Jfacturer's instructions. Allow the machine to come to oper-
iating temperature and equilibrate, (allow 4 h rif continuous
punning time and between 25 to 35 min after a spray cycle).
Ipnless other temperatures and tolerances are specified in the
japplicable ASTM test method or detailed material specifica-
Itions, the black-panel temperature shall be 63 " 2.5C (145
|5T) (Note 3). '
'
5.4.2 Compare the black-panel temperature with the spec
ification. If the black-panel temperature is within 2.5 C or
|5F of specification, no adjustment is necessary. If the
I observed temperature difference is greater than 2.5C or 5F,
| adjust the temperature controller and recheck the black-
| panel temperature during the next cycle. It is recommended
p that this : procedure be performed. after every 200 h of
l machine operation.
No t ' 3--Where desired, othec black-panel temperatures may be I employed provided they are specifically noted in the report of test I results. Instructions for adjusting the intensity of the arc and the fading * rate are supplied with the apparatus or are available upon request from
the manufacturer. Consideration should always be given to installing the J instrument in a room where the temperature arid humidity conditions i are controlled. The magnitude of the effects due to variation in the air
supply can only be partially determined when the intake air is not controlled.
.5.5 The water from the specimen spray should strike the test specimens in the form, of a fine spray equally distributed over the test specimens. Unless otherwise specified in the applicable ASTM test method or detailed material specifica tion, the waier pressure, number, and type of nozzles should'
be in accordance with the detailed requirements for the various types of apparatus as indicated in Figs. 4 to 6. The pH of the water shall be 6.0 to 8.0, contain less than 1 ppm solids and leave no, objeptional deposits or stain on the specimens.' The'presence of very Idw levels of silicates in spray water has been shown to leave deposits on some specimens. If is recommended that the temperature of the water should be 16 5 'C (60 9"F), Recirculation is not recommended and must not be done unless the recirculated water is treated to meet the above requirements.
5.5.1 Set the cycle control unit cam until the machine is in a spray cycle. Observe the spray manifold. All spray heads should spray a stream of mist or water which reaches the panel surface. If any of the spray heads are not satisfactory, remove the spray manifold and clean each spray head. Install the manifold and recheck the spray operation.
5.6 The flat glass filter panes used in Types E or EH devices cannot be used for more than 2000 h. Monitor age and position of the filter panes so that the oldest can be

Replace the oldest of the filter globes every 1000 hi Replace the filter globe in Type H or HH devices after 2000 h of use or when pronounced discoloration or milkiness develops. Clean filters each day by wiping, with a clean, dry non-abrasive cloth or towel. Filters can also be cleaned by washing with water, or a solution of detergent and water.
5.7 Unless otherwise specified in the applicable ASTM test method or detailed material specifications, operate Types E and EH apparatus with the filters in place' and with the carbon electrodes specified in Table 1. If operated without filters or with other types ofcarbon electrodes, state this in the report of test results.
METHOD 1--CONTINUOUS EXPOSURE TO LIGHT AND INTERMITTENT EXPOSURE TO WATER SPRAY
6. Apparatus
6.1 The apparatus may be any of the recommended type equipped with water spray nozzles.
6.2 Program the instrument for continuous light and intermittent water spray according to the manufacturer's instructions. Since there are numerous light and water spray
cycles which can be used, the cycle program selected must be by mutual agreement among the interested parties. Histor ical convention has established a cycle Of 102 min of light followed by 18 min of light and water spray. This. cycle permits the attainment ofthe maximum black-panel temper* attire during the light only portion of`the exposure.
6.2.1 When testing the effects of photodegradation only, the water spray may be omitted (refer to Method 3)'.
6.3*In Types DH, EH and HH apparatus, dry and wet bulb temperature controls, humidifier and immersion heater controls should be adjusted as specified.
6.4 In Type H and in Types D and E with humidifier, humidity may be adjusted but not controlled.
METHOD 2--ALTERNATIVE EXPOSURE TO LIGHT AND DARKNESS AND INTERMITTENT EXPOSURE TO WATER SPRAY
7. Apparatus
7.1 The apparatus shall be Type DH, EH and HH apparatus with automatic humidity control and water spray nozzles.
7.2 Operation during the light on period should be as described in Section 5.

otherwise'specified, in accordance with one of the following: 8.3.1 Versus One AA TCCBlue Wopl Lightfastness Stand
ard--Expose the test specimen and any mutually agreed upon AATCC Blue Wool Lightfastness Standard partially masked until the difference between its masked and un masked portion exhibits a color change equal to Step 4 of the
ISO Gray Scale. Report the results by any mutually agreedupon method of measuring change in the test specimen.
8.3.2 Versus Set of AATCC Blue Wool Lightfastness Standards--Expose the test specimen and a set of AATCC Blue Wool Lightfastness Standards partially masked until a
maximum permissible amount of change, as determined by specified or mutually agreed-upon method of measurement, occurs in the test specimen. Assign it a classification number equal to that of the numbered standard that most nearly exhibits a change in color equal to Step 4 on the ISO Gray Scale. Where one standard shows a color change greater than Step 4 and the next higher number standard shows less than a Step 4 color change, an intermediate or half-grade rating may be used.

Designation: G 26 - 90
Standard Practice for
Operating Light-Exposure Apparatus (Xenon-Arc Type) With and Without Water for Exposure of Nonmetaiiic Materials1
This standard is issued under the fixed designation G 26; the number immediately following the designation indicates the year df original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. P superscript epsilon (<) indicates an editorial change since the last revision or reapproval.
I. Scope
1.1 This practice covers the basic principles and operating procedure for water- or light-exposure apparatus, or both, employing a xenon-arc light source.
Non I --This practice combines the practices previously referred to as G 26 and G 27. Practice G 27, for Operating Xenon-Arc Type Apparatus for Light Exposure of Nonmetaiiic Materials*, has been discontinued since it is now covered in this edition of G 26 under Test Methods C and D.
1.2 This practice does not specify the exposure conditions best suited for the material to be tested, but is limited to the method of obtaining, measuring, and controlling the condi tions and procedures of the exposure. Sample preparation, test conditions, and evaluation of results are covered in ASTM methods or specifications for specific materials.
i .3 This practice includes four test methods: 1.3.1 Test Method 1--Continuous exposure to light and intermittent exposure to water spray. 1.3.2 Test Method 2--Alternate exposure to light and darkness and intermittent exposure to water spray. 1.3.3 Test Method 3--Continuous exposure to light without water spray. Exposure conditions are characteristic of those specified by AATCC Test Method 16E 1976. 1.3.4 Test Method 4--Alternate exposure to light and darkness without water spray. Exposure conditions charac teristic of those natural conditions experienced when ex posing are in accordance with Practice G 24. 1.4 This practice may involve hazardous operations and equipment. Thispractice does not purport to address all ofthe safety problems associated with its use. It is the responsibility ofthe user ofthis practice to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use. 1.5 The values stated in SI units are to be regarded as the standard. The inch-pound equivalents of the SI units may be approximate.

iMeans shall be provided for adjustment of relative humidity. |The specimen rack shall rotate at 1 0.1 rpm.
N' 2--In the commercial descriptions of the four types, the term
|t``cycle" is defined as each time interval of light, darkness, and water jispray that is specified differently in accordance with the different testing Imethods.
4.1.1.2 Type AH--The exposure apparatus shall be idenitical to Type A except it shall have automatic humidity ficontrol.
4.1.1.3 Type B--An exposure apparatus in which the I source of radiant energy shall be a water-cooled xenon-are II vertically located at the central axis of a 960-mm (37.75-in.) 1 diameter specimen rack. Means shall be provided1 for auto-
K matic programming of temperature and cycles. Means may
1 be provided for adjustment of humidity. The specimen rack I shall rotate at 1 0.1 rpm.
4.1.1.4 Type BH--The exposure apparatus shall be sim ilar to Type B except it shall have automatic humidity j control.
4.1.2 The xenon-arcs employed shall be of the "long arc" j water-cooled type operated through suitable reactance trans(formers and electrical equipment from a 50 or 60-Hz power I supply. They shall employ cylindrical inner and outer optical f filters to direct the flow of cooling water and to simulate.a designed spectral energy distribution.
4.1.2.1 For the purpose of this practice, the xenon-arc lamp shall consist of a quartz xenon burlier tube and one of the following optical filter combinations:6-7
fl Norton, Kiuntke, and Connor, Canadian Textile Journal, CTJOA, May 1969. 7 Corning 7740 Pyrex (borosilicate), Coming 460! 1R absorbing visible transmitting, Kimble R6 soda lime glass tubing, and General Electric QA-204 quartz tubing of proper dimensions have been found suitable for use as xenon-arc optica] filters Available from Atlas Electric Devices Co., 4114 N. Ravenswood Ave., Chicago, IL 60613.
(a) Borosilicate glass inner and outer optical filter to simulate the spectral power distribution (SPD) of natural daylight throughout the actinic region.
lb) Infrared absorbing glass inner optical filter with quartz outer optical filter to simulate the SPD of natural daylight (300 to 1000 nm).
(c) Borosilicate glass inner optical filter with soda lime glass outer optical filter to simulate the SPD of natural daylight (actinic wavelengths) filtered through window glass.
(d) Infrared absorbing glass inner and outer optical filter to simulate the SPD of natural'daylight (310 to 1000 nm) filtered through window glass.
(e) Quartz inner and outer optical filter to approximate sunlight intensities unfiltered by the earth's atmosphere.6 7
4.1.2.2 To prevent loss in levels of irradiance due to excessive solarization .and to .prevent possible breakage caused by stresses in optical filters exposed to high-intensity UV energy, inner optical filters8 shall be replaced periodi cally. Suggested intervals are 300 and 400 h for Types A and B, respectively. The outer optical filter shall be replaced after 1500 and 2000 h for Types A and B, respectively.
4.1.3 Distilled or deionized water should be recirculated past the burner at a flow rate sufficient to remove excess heat. Passing water through a cartridge demineralizer in stalled in the recirculation line just ahead of the lamp minimizes contamination of the quartz envelope of the burner. A heat-exchange unit should be used to cool the recirculated lamp water.
4.1.4 Since xenon-arc lamps, like all gas discharge lamps, will have a progressive drop in radiation output with continued use, and since optical filters will change in their

transmission characteristics, provision shall be made in the
apparatus (automatically or manually) for progressively in creasing the wattage of the lamp to minimize changes in the intensity of the radiation at the face of the sample. The greatest change in both the xenon burner tube and optical filters occurs in the first 20 h of use. For this reason, burners
and optical filters preaged by the instrument manufacturer are recommended for critical testing when a more rapidly changing rate of intensity is undesirable. For routine testing on a comparative basis, the 20 h of preaging may be omitted.
4.1.5 Many nonmetallic materials are selectively ab sorbing. The energy that a molecule absorbs depends upon the wavelength of the incident radiation.9 It is desirable to monitor the level of irradiance of the photochemically
effective wavelengths if intercomparisons are to be made among samples not exposed simultaneously. Samples may then be exposed to known amounts of irradiation, the time
integral of irradiance. 4.1.5.1 Where radiometers capable of monitoring discrete
portions of a continuous spectrum are available, exposure to a mutually agreed-upon level of irradiation may be specified
as the exposure interval in place of a time interval. {a) When using the optical filter combination described in
4.1.2.1 (a), the suggested minimum spectral irradiance levels are:
.2 W/m2/nm band at 320 nm ,35 W/mVnm bancbat 340 nm ' , .5 , W7m2/nm band at 380 nm . .75 W/m2/nm band at 420 nm.
.
.
(6) When using the optical filter combination described in 4. i .2.1 (c), the suggested minimum spectral irradiance levels are: ' '
.2 W/m2/nm band at 340 nm .45 W/m2/nnt band at 380 nm .7 W/m2/nm band at 420 nm
(c) Operating at the suggested minimum' levels approxi mates the average daily solar irradiance under ideal condi tions. It is about half of the maximum values for total irradiance on a Horizontal plane when the sun is at 90" altitude as reported in CIE No. 20. When irradiance is monitored and periodic manual adjustment of wattage is made to compensate for changes of intensity, no lamp
assembly should be used that cannot maintain the minimum level of irradiance within a 10 % tolerance at the monitored wavelength, irradiation expressed as joules per square metre is the product of irradiance x exposure time in seconds.
4.1.5.2 Xenon-arc type equipment not having a radiom
eter shall be operated with periodic increases in wattage to minimize any drift in levels of irradiation. Such intervals shall be established by the parties concerned or follow the suggested schedule below in 4.1.5.2 (a).
N' 3--The use of suggested wattage steps does not imply that
irradiance will be maintained at levels equivalent to those obtained when employing a light monitor. They are intended as a guide to minimize the reduction of UV intensity with maximum lamp longevity when using either Test Method A or C for 2.5, 6, or 6.5-kW lamps,
respectively.

4.1.6 Specimens should be mtmnted on a rack rotating about the, lamp at a 'diStaiice such that the location of each specimen assures that the irf&diance incident on its surface does not'vary by more than 5 % from the average. Figure'4
illustrates'a rack meeting this condition. '4.1.7 Any apparatus--that does hot comply with the
condition of 4.1.6 shall not have a variation in irradiance exceeding 10 % of the average, and may require specimen
rearrangement during exposure, in accordance with the test procedure, in order to minimize the variability in radiant exposure.
4.1.8 Testing temperatures should be'measured and regu lated on the basis of a black panel thermometer unit
mounted on the specimen rack so that the face of the unit is in the same relative position and is subjected to the same influences as the test specimens. The black panel thermom eter unit should consist of a .stainless steel panel about 70 by 50 by 0.95 mm (2.750 by 5,875 by 0.0375 in.), to which a stainless steel bimetallic dial-type thermometer is mechani cally fastened. This thermometer should have a stem approx imately 4 mm (0.16 in.) in diameter with a 44.5-ram
{1.75-in.) dial. The sensitive portion extending about 38 mm (1.5 in.) from the end of the stem should be located in the center of the panel approximately`64 mm (2.5 in.) from the top and approximately 48 mm (1.875 in.) from the bottom

The face of the panel with the thermometer :em attached should be finished with a baked-on black infrared-absorbing coating having good resistance to light. 4.1.8.1 A thermocouple or resistance bulb thermometer ounted at the center face of the black panel, which rovides temperature values equivalent to the dial tkermom-
iter, may be substituted. 4.1.9 A blower unit in the base of the apparatus should
provide a flow of air through the test chamber and over the
test specimens. Control ofspecimen and black-panel tempertture should be accomplished by thermostatic control of the temperature of the constant volume of air from the blower, lack-panel temperatures should be read through the fvindow in the test chamber door without opening the door.
4.1.10 Apparatus operated as a light- and water-exposure st shall be equipped with a specimen spray unit as illusated in Figs. 2 and 3. All components of the specimen spray ||mit should be fabricated from stainless steel, plastic, or other Bmaterial that does not contaminate the water. Apparatus operjjated orily as a light-exposure test are not required to have the
Bspecimen spray unit or, if present, it should not be used. If 4.1.11 Types A, AH, BH, and some Type B apparatus are ' equipped with an electrically operated vaporizing unit for padding moisture to the air as it passes through the condi. tioning chamber in the base section prior to its entry into the itest chamber of the apparatus.
' 4.1.11.1 In Types A and B, the vaporizing unit, when
I manually turned on, may operate continuously while the apparatus is in operation. Type A and some Type B apparatus may be programmed to operate the vaporizer [during a dark cycle only. The temperature of the water, with
(which the vaporizer is supplied, is not controlled. In Type B ^apparatus not supplied with a vaporizing unit, the relative
humidity within the test chamber is governed by evaporation % of water in the bottom of the chamber and from water
i emitted through the specimen spray unit.. 4.1.11.2 In Types AH and BH apparatus, operation of the
vaporizer is controlled automatically by a wet-bulb thermo stat. The temperature of the water supplied to the vaporizer ; is regulated automatically by thermostatically-actuated elec-
[ trie immersion heaters. Control automatically shifts between ^ two separate sets of thermostats as the arc lamp is turned on ' and off by the program control unit.
4.1.12 In Types A, B, AH, and BH apparatus containing vaporizing units, relative humidity is determined from wet| and dry-bulb thermometers located in the air stream at the 5 vaporizer's point of exit from the test chamber. | 4.1.12.1 Determine the relative humidity for Type B I apparatus not equipped with a vaporizing unit from wet- and 4 dry-bulb thermometers mounted in holders on the specimen rack so that their sensitive portions are in the same relative position as the face of the test specimen but shielded from
the radiation. 4.1.12.2 Any apparatus with a vaporizing unit operated
with the unit and immersion heaters turned off will provide essentially the same conditions of relative humidity as are produced in Type B apparatus without a vaporizing unit.
4.1.13 The apparatus shall include means for measuring the following:
4.1.13.1 Wattage of the xenon-arc lamp, 4.1.13.2 Irradiance at the specimen rack,
4.1.13.3 Black-panel temperature, 4.1.13.4 Dry-bulb temperature (test chamber), 4.1.13.5 Wet-bulb temperature (test chamber), 4.1.13.6 Exposure interval, and 4.1.13.7 Water spray pressure when applicable. 4.1.14 Where specified, the apparatus shall include means for regulating or controlling the following: 4.1.14.1 Wattage of the xenon lamp, 4.1.14.2 Irradiance or irradiation, or both, at the spec imen rack, 4.1.14.3 Temperature (test.chamber), 4.1.14.4 Relative humidity (test chamber),
4.1.14.5 Light-dark-spray-humidity-temperature cycles, and
4.1.14.6 Water spray pressure when applicable. 4.2 Air-Cooled Type:10 4.2.1 The apparatus employed shall use an air-cooled xenon-arc lamp as the source of radiation and should be one of the following types, or their equivalent: 4.2.1.1 Type C--Air-cooled xenon-arc apparatus, 1500 W, 158-mm (6.2-in.) diameter specimen rack, with auto matic programming of cycles and humidity. The specimen rack should rotate at 5.2 0.1 rpm. 4.2.1.2 Type D--Air-cooled xenon-arc apparatus, 4500 W, 360-mm (14.2-in.) diameter specimen rack, with auto matic programming of temperature, cycles, and humidity. The specimen rack should rotate at 3.7 0.1 rpm. 4.2.1.3 Type E--Air-cooled xenon-arc apparatus, three lamps operating simultaneously at 4500 W each, 610-mm (24.1-in.) diameter specimen rack, with automatic program ming of temperature, cycles, and humidity. The specimen tack should rotate at 2.0 0.1 rpm. 4.2.2 The xenon arcs employed in Types C and D should be of the medium-pressure, air-cooled type and one or more optical filters shall be fitted between the light source and the samples to filter out undesired wavelengths of radiation. A combination of optical filters recommended by the manufac turer shall be used to simulate (/) sunlight in the open, (2) sunlight behind window glass, or (5) any other simulated solar irradiation condition desired. 4.2.3 All gas discharge lamps have a progressive_drop in radiant output with continued use. For Types C and D, it is recommended to exchangrthe IR-optical filters for new ones after 3500 h of use. Answering the purpose, not all seven IR-optical filters of the filter lantern should be exchanged at the same time but each should be exchanged after it has been running for 3500 h. For Type E which has three lamps, one lamp should be replaced every 500 hours to minimize the overall drop in radiant output. For Type E, the three partial preaged filters should be cleaned monthly and replaced after five years of normal usage. 4.2.4 Specimen holders should rotate around the arc, describing a cylindrical surface, so that specimens may face, or be turned opposite to, the arc. No part of the specimens shall be above or below the ends of the arc. Repositioning of specimens in upper, center, or lower positions can improve the uniformity of intensity of the exposure.

5. General Procedure
5. L Check to be sure the apparatus is operating properly at the start of each test. Check the lamp operation at 100-h intervals to be sure the burner tube and optical filters are dean and that they have not exceeded the maximum recommended period of use.
5.2 Program the instrument to operate in the continuous light-on mode without water spray. Fill the specimen rack with blanks and the black-panel thermometer. Operate the instrument in this mode while regulating the chamber dry-bulb temperature to provide the desired black-panel temperature of 63 3C (145 5F).
5.3 When the chamber dry-bulb temperature has been regulated, adjust instruments with automatic humidity con trol to the desired relative humidity (Types C, D, and E) or to the chamber wet-bulb temperature (Types A and B) at the level that will ensure the desired relative humidity.
5.4 In Types A, B, C, D, and E apparatus, use the type and iiumber of spray nozzles (Figs. 2 and 3) recommended by the manufacturer and operate at a pressure of 124 to 172 kPa (18 to 25 psi), measured at the nozzle unless otherwise recommended. The water shall have a pH of 6.0 to 8.0, contain less than 20 ppm solids, and leave no deposit or stain on the specimens after continued exposure in the apparatus. The temperature of the water should be 16 + 5C (60.8 9F), and recirculation of the water shall not be permitted . unless the recirculated water meets the above requirements. Pass the specimens through the spray once in each minute or revolution ofthe rack during the spray cycle. Allow the water to strike the test specimens in the f6rm ofa fine spray equally distributed over the specimens.
5.5 The temperature of the rack spray water should be sufficiently low to reduce the specimen temperature below the dewpoint when the specimen is continuously sprayed during a dark cycle.
5.6 Reference Standards: 5.6.1 AATCC Blue Wool Lightfastness Standards.3
N' 4--The eight standards L-2 to L-9 have been made by
blending wool dyed with the fugitive dye Erio Chrome Azuroie B and wool dyed with the fast dye Indigosol Blue AGG in different propor tions. The blended wools were spun into yarns and the yarns woven into cloths. Each standard is approximately twice as fast as the next lower
numbered standard. It has been found that when new lots of the standards are produced, the amounts of .the dyes required and tire properties of the two wools in the blends are often different from those
used originally. The dyeing strengths and blending proportions would
therefore be misleading, and they are intentionally not specified.
5.6.2 Any standard sample established by mutual agree ment between the purchaser and the supplier.
5.6.3 ISO Gray Scale for Assessing Change in Color.n 5.7 When the material to be evaluated is suspected of being very sensitive to variations in radiant exposure, and the apparatus does not meet the requirement of 4.1.6, it is the responsibility of the concerned parties to mutually agree upon a rearrangement schedule for specimens as part of the11
exposure program in order to minimize any effect that
variations in irradiance might have as a function of specimen position.
TEST METHOD A--CONTINUOUS EXPOSURE TO LIGHT AND INTERMITTENT EXPOSURE TO WATER SPRAY
6. Procedure
6.1 Apparatus shall be Type A, B, AH, BH, C, D, or E light-exposure device.
6.2 Program the instrument for continuous light and intermittent water spray in accordance with the manu facturer's instructions. Choice of the program.selected will be by mutual agreement among the interested parties. Histor- ; ical convention has established a cycle of 102 min of light 1 followed by a cycle of 18 min of light and water spray as a commonly accepted program that permits the attainment of the maximum black-panel temperature during the light-only portion of the cycle.
6.3 In Types AH and BH apparatus, adjust dry- and ! wet-bulb temperature controls, humidifier, and immersion ; heater controls to maintain the desired conditions as speci- ; fled in Section 5. In Types C, D, and E, adjust the chamber temperature and humidity controls to maintain desired j conditions as specified in Section 5.
6.4 In Types A and B with humidifier, humidity may be adjusted but not controlled.
6.4.1 Type B instruments without a humidifier musi operate with whatever humidity occurs from the evaporation of water in the bottom of the test chamber and from j specimen spray.
TEST METHOD B--ALTERNATE EXPOSURE TO LIGHT AND 1 DARKNESS AND INTERMITTENT EXPOSURE TO WATER SPRAY

test. The electrical stress is produced by connecting the test specimen to the negative terminal of a source of direct current and by connecting an anode to the positive terminal. Electrical instrumentation is provided for measuring the current flowing in the cell. The electrical potential is also measured and the specimen is physically examined at intervals during the test period and upon conclusion of the test.
3.1.1 The cathodic stress is applied under conditions of a constant-elevated temperature.
4. Significance and Use
4.1 Damage to pipe coating is almost unavoidable during transportation and construction. Breaks or holidays in pipe coatings may expose the pipe to possible corrosion since, after a pipe has been installed underground, the surrounding earth wil be moisture-bearing and will constitute an effective electrolyte. Applied cathodic protection potentials may cause loosening of the coating, beginning at holiday edges. Sponta neous holidays may also be caused by such potentials. This test method provides accelerated conditions for cathodic disbondment to occur and provides a measure of resistance of coatings to this type of action.
4.2 The effects of the test are to be evaluated by physical examinations and monitoring the current drawn by the test specimen. Usually there is no correlation between the two methods of evaluation, but both methods are significant. Physical examination consists of assessing the effective contact of the coating with the metal surface in terms of observed differences in the relative adhesive bond., It is usually found that the cathodically disbonded .area propa gates from an area where adhesion is zero to an area where adhesion reaches the original level. An intermediate zone of decreased adhesion may also be present.
4.3 Assumptions associated with test results include: 4.3.1 Maximum adhesion, or bond, is found in the coating that was not immersed in the test liquid, and 4.3.2 Decreased adhesion in the immersed test area is the result of cathodic disbondment. 4.4 Ability to resist disbondment is a desired quality on a comparative basis, but disbondment in this test method is not necessarily an adverse indication of coating performance. The virtue of this test method is that all dielectric-type coatings now in common use will disbond to some degree, thus providing a means of comparing one coating to another. 4.5 The current density appearing in this test method is much greater than that usually required for cathodic protec tion in natural environments. 4.6 That any relatively lesser bonded area was caused by electrical stressing in combination with the elevated and or

depressed temperature and was not attributable to an anomaly in the application process. Ability to resist disbondment is a desired quality on a comparative basis, but most insulating materials will disbond to some extent under the accelerated conditions of this test. Bond strength is more important for proper functioning of some coatings than others and the same measured disbondment for two different coating systems may not represent equivalent loss of corro sion protection.
4.6.1 The amount of current flowing in the test cell is a relative indicator of the extent of areas requiring protection against corrosion; however, the current density appearing in this test is much greater than that usually required for cathodic protection in natural, inland soil environments.
4.6.2 Test voltages higher than those recommended may result in the formation of chlorine gas. The subsequent chemical effects on the coating could cast doubt on the interpretation of the test results.
5.Apparatus
5.1 Test Vessel--A suitable nonreactive vessel shall be used, capable of withstanding internal heating at not less than 60C and suitable for continuous circulation of the electrolyte. A 19-L (5-gai) cylindrical glass vessel has been found suitable, having an approximate diameter of 300 mm (12 in.) and a depth of 300 mm. A flat bottom is required for operation of a magnetic stirring rod. Dimensions of the vessel shall permit the following requirements:
5.1.1 Test specimens shall be suspended vertically in the vessel with at least 25 mm (1 in.) clearance, from the bottom.
5.1.2 Test specimens shall be separated by not less than 38 mm (1 lh in.), and a vertically suspended anode can be placed at an equal distance from each specimen not less than the separation distance.
5.1.3 Test specimens shall be separated from any wall of the vessel by not less than 13 mm (`A in.).
5.1.4 Depth of electrolyte shall permit the test length of the specimen to be immersed as required in 7.4.
5.1.5 The reference electrode may be placed anywhere in the vessel, provided it is separated from the specimen and from the anode by not less than 38 mm (11h in.}.
5.2 Anode--The anode shall be provided with a factory' sealed, insulated copper wire lead.4
5.3 Connectors--Wiring from anode to test specimen shall be 4107 cmil (14-gage Awg), minimum, insulated copper. Attachment to the test specimen shall be by sol dering or brazing to the nonimmersed end, and the place of attachment shall be coated with an insulating material. A junction in the connecting wire is permitted, provided that it is made by means of a bolted pair of terminal lugs soldered or mechanically crimped to clean wire ends.
5.4 Holiday Tools--Holidays shall be made with conven tional drills of the required diameter. For use in preparing small-diameter pipe specimens such as 19-mm (%-in.) nom inal diameter pipe, the use of a drill modified by substantially grinding away the sharp cone point has been found effective in preventing perforation of the metal wall of the pipe. A
4 Duriryn. a material found suitable for this purpose is available from Duriron Co., Inc.. Dayton. OH.
sharp-pointed knife with a safe handle is required for use in making physical examinations.
5.5 Multimeters:
5.5.2 Multimeter, for direct current, having an internal resistance of not less than 10 Mft and having a range from 0.01 to 5 V for measuring potential to the reference electrode.
5.5.2 Multimeter, for direct current, having an internal resistance of not less than 11 MO and capable of measuring as low as 20 pV potential drop across a shunt in the test cell circuit
5.5.3 Multimeter, for initial testing of apparent coating resistance.
5.6 Reference Electrode--Saturated Cu CuS04 elkttrode having a potential of -0.316 V with respect to-the standardhydrogen electrode shall be the standard of reference in these1: test methods. Other electrodes may be used but measure-* meats thus obtained shall be converted to the Cu CuS04 reference for reporting by making the proper correction. "
N' I--A saturated Cu CuSO, electrode reading --1.50 V at 25"C
will read -1.53 V at 60"C, a scale increase of 0.03 V.
5.6.1 A saturated calomel electrode at 25C is converted to Cu CuSO,, by adding -0.07 V to the observed reading. If . the saturated calomel electrode reads -1.43 V at 25C, it will read -1.46 V at 60C, a scale increase of 0.03 V, It follows that a saturated calomel electrode reading of--1.46 V at 60C is equal to a saturated Cu CuS04 reading of--1.50 V at 25"C.
5.6.2 A 0.1 normal calomel electrode at 254C is converted * to Cu CuS04 by subtracting -0.02 V from the observed reading. Since the potential change due to an increase from 25 "C to 60C is negligible, it follows that a 0.1 normal calomel electrode reading --1.52 V at 60C is equal to a saturated Cu CuS04 reading of -1.50 V at 25C.
5.7 Thermometers, two, mercury-filled type, accurate to \ 1 "C. One shall be of the fuLI-immersion type for measuring temperature near the bottom of the vessel, and a second j thermometer shall be of the partial-immersion type for ; measuring temperature near the top-of the vessel.
5.8 Combination Heater Plate, with built-in magnetic j stirrer, or equivalent, shall be used for heating and stirring the electrolyte. The heater shall be adjustable to produce and control a temperature of 60 1C in the test vessel.
5.9 Direct-Current Rectifier, capable of supplying con stant current at a voltage of 1.50 0.01 V, as measured between the specimen and reference cell.
5.10 Thickness Gage, for measuring coating thickness in accordance with Test Method G 12.
5.11 Precision Resistor, lft 1 %, 1 W (min), to be used in the test cell circuit as a shunt for current.
5.12 Carbon or Stainless Steel Electrode, used temporarily. with the volt-ohm-meter to determine apparent initial hol iday status of the test specimen.
5.13 Additional Connecting Wires, 4107 cmil (14-gage Awg), minimum, insulated copper.
5.14 Brass Studs, used at a terminal board, together with alligator clips or knife switches, for making and breaking circuits. Alligator clips shall not be used to connect the electrodes or specimens at the top location of test cells.

. Test Specimen
7.1 The test specimen shall be a representative piece of jjroduction-coated pipe. One end shall be plugged, sealed, or capped.
7.2 One holiday shall be made, in the middle of the immersed length by drilling a radial hole through the coating o that the angular cone point of the drill will fully enter the Steel where the cylindrical portion of the drill meets the steel surface. The drill diameter shall be not less than three times the coating thickness, but it shall never be less than 6 mm. (% in.) in diameter. The steel wall of the pipe shall not tie perforated. With small-diameter pipes, where there is danger of perforating the pipe, the holiday shall be started with a standard,60" cone point and finished with a drill that has had a substantial portion of the cone point ground away.
No t ' 3--Before making the holiday, see 7.5.
7.3 The end of the pipe which will protrude above the
immersion line shall be provided with suitable supporting means and a separate wire connection for electrical purposes, soldered, or brazed to the pipe. The protruding end, in cluding hanger and wire connections, shall be protected and sealed with an insulating coating material.
7.4 The specimen test area shall consist of the area between the edge of the bottom end seal and the immersion line. The bottom end seal area shall not be considered part of the area tested. Coated specimens of any suitable diameter and length of pipe may be used, but the immersed area shall be not less than 23 200 mm2 (36 in.2). An area of 92 900 mm2 (1 ft2) has been found preferable when convenient.
7.5 The continuity ofthe coating and efficiency.ofthe end seal, shall be tested before making artificial holidays as follows:
7.5.1 Immerse the test specimen and a carbon or stainless steel electrode in the electrolyte. Connect one terminal of the ohmmeter to the test specimen and the other terminal to the carbon or stainless steel electrode. Measure the apparent resistance in ohms, making two determinations: one with the specimen connected to the positive terminal of the ohmmeter, and one with the specimen connected to the negative terminal. The lowest of the two readings should be not less than 1000 Mfi, however, the test may be conducted with a low reading less than 1000 MS2, provided that the condition is taken into account in evaluating results.
8. Procedure
8.1 Immerse the test specimen in the electrolyte and connect it to the anode as shown in Fig. 1. Adjust the rectifier-.or voltage divider so that the potential between specimen and reference cell is -1.50 0.01 V at 25C (-1.53 0.01 V at 60C) (see Fig. 2). Position the holiday to face toward the anode. Space the anode with respect to test specimens as required in 5.1.

additions of preheated, distilled, or demineralized water as required.
8.2 The temperature of the electolyte surface to bottom shall be not less than 60 3'C. The electrolyte shall be continuously circulated by means of the stirring apparatus or equivalent. The maximum temperature shall be attained 4 1 h after starting the heater and immersing the specimen.
N' 4--Throughout the test period, ejected sealant or salt deposits,
or both, may form near, or partially obstruct the intentional coating holiday described in 7.2. No attempt shall be made to dear ihe holiday while the test is in progress.
8.3. Electrical Monitoring Schedule: 8.3.1 Electrical measurements shall be made on the start up day and on each normal working day thereafter for the duration of the test. A maximum of three consecutive nonworking days shall be preceded by at least two working days; one non-working day or two consecutive non-working days shall be preceded by at least one working day, except at start-up and termination when three and two working days are required, respectively. 8.3.2 Electrical measurements characterizing the start of the test are defined as the average of measurements taken on the second and third days after immersion. 8.3.3 Electrical measurements characterizing intermediate and terminal time spans shall be taken on two successive days prior to and including the target date. 8.4 Electrical measurements and adjustments made each normal working day: 8.4.1 Measure E2, the stress potential in volts between the test specimen and the reference electrode, without discon necting the energized anode or specimen from the circuit.
Use the high-resistance voltmeter described in 5.5. The stres-, potential, Ely should measure -1.50 0.01 V at 25"C (-L53 0.01 V at 60C); if it does not, adjust the rectifier or voltage divider accordingly.
8.4.2 After Ez has been measured and adjusted, if neces sary, measure /,, the current demand in amperes, by determining the potential drop across the l-.Q precision resistor permanently installed in the test cell circuit with the high-resistance voltmeter described`in 5.2. The voltage reading will be numerically equal to amperes.
N' 5--An alternative method of measuring current _deman_
utilizes a zero-resistance ammeter. In this method, the wire connection between the test specimen and~anode is temporarily broken and a zero-resistance ammeter temporarily interposed between the specimen and the anode. Reconnect the specimen to the anode with the connector wire as soon as this measurement is completed.
8.4.3 Measure j, the polarized potential, in volts, usiry the high-resistance voltmeter described in 5.5 connected between the test specimen and the reference electrode it1 follows:
8.4.3.1 Disconnect the anode from the test specimen while closely observing the high-resistance voltmeter. As the instrument pointer falls, it will dwell significantly at the polarized potential before recording further. The dwell point is j.
8.5 Standard duration of the test period shall, be 30 days (720 h) in the energized test vessel including warm-up and cool-down times, unless longer test periods are specified.
8.6 A physical examination shall be performed immedi ately upon termination of the test period as follows:
8.6.1 Before examination, wash the test specimen care-
1084

# G 42
der gently flowing tap water without disturbing estructive effects. Adjust the temperature of the tap that it approximates that of the room temperature. Examine the entire immersed area visually for any
of new holidays and loosening of coating at the
all holidays, including the artificial holiday. Drill a new test hole in the coating in an area that
immersed, staying away from the immersion line Scut end. Recommended distances are given in Fig. 3. the same drilling procedure described in 7.2. ! In order to gage or calibrate the lifting technique, to lift the coating at the new test hole with the point arp knife after, making cuts through the coating ting at the center of the hole. Inability or relative ce to lifting or disbonding the coating shall be red the adhered or bonded condition of the untested with respect to the lifting technique used. Determine if the coating has been loosened at the sedjest hole by attempting to lift the coating with the f a'sharp knife after making cuts through, the coating
intersecting at the holiday or point of inspection using the same technique applied in 8.6.4. Classify coating that can be lifted or disbonded more readily than at the new test hole as unsealed area. Measure the unsealed area.
N' 6--The use of a transparent film having a grid laid out in small
squares such as 2.54 mm (0.1 in.) on a side has been found useful. The film is placed against the unsealed area and the boundary ofthe unsealed area is traced on the grid. The area is then obtained by counting the squares within the bounded area.
8.7 Determine and record the resistivity and pH of the electrolyte at the beginning and end of the test period.

3. Description of Terms Specific to This Standard
3.1 irradiance--the radiation incident on a surface ex pressed in W/m2. Irradiance is the total of the incident radiation at all wavelengths. Forty watt fluorescent lamps of the UV-B and UV-A types generate similar amounts of
irradiance. However, since this irradiance is distributed, at, different wavelengths, the photochemical, effects caused by these different lamps vary greatly. Therefore, irradiance should not be used,to- compare DY light sources,::.
3.2 spectral irradiance--distribution of irradiance as a function of wavelength. It is expressed in W/m2 per wave length band. The spectral irradiance of sunlight is often sfrowii as'W/m2 per 10 nm band; The spectral irradiance of fluorescent UV |amps should be shown in b^nds 1 or 2 nni. wide. Spectral irradiance is the proper method for comparing' sources with different energy distributions.
3.3 spectral energy distribution-(SED)--general term for
the characterization of the amount of radiation present at each wavelength. SEDs can be expressed by power in watts, irradiance in W/m2, or energy in joules. Tjie shape of the SED. would be identical in all of these units. Fluorescent lamps are frequently described by relative SEDs which show the amount of radiation at each wavelength as a percentage ofthe amount of radiation at the peak wavelength. Fig. 1 is a relative SED.
3.4 ultraviolet regions--CIE Publication No. 20 (1972) divides the ultraviolet spectrum into three regions: UV-A, radiation in wavelengths between 315 nm and 400 nm; UV-B, radiation in wavelengths between 280 nm and 315 nm; and UV-C, radiation in wavelengths shorter than 280 nm.
3.5 fluorescent UV lamp-lamp in which radiation at 254 nm from a low-pressure mercury arc is transformed to longer wavelength UV by a phosphor. The spectral energy distribu tion of a fluorescent UV lamp is determined by the emission

p.l Specimens are alternately exposed to ultraviolet light e and to condensation alone in a repetitive cycle.
%2 The UV source is an array of fluorescent lamps, with p emission concentrated in the UV range.
4.3 Condensation is produced by exposing the test surface ?a heated, saturated mixture of air and water vapor, while fe reverse side of the test specimen is exposed to the cooling fluence of ambient room air. 4.4 The exposure condition may be varied by selection of: e fluorescent UV lamp; the timing of the UV and ndensation exposure; the temperature of UV exposure; d the temperature of condensation exposure.
Significance and Use
5.1 The use of the apparatus under this practice is tended to simulate the deterioration caused by water as 'n or dew and the ultraviolet energy in sunlight. It is not tended to simulate the deterioration caused by localized eather phenomena, such as atmospheric pollution, biologcal attack, and salt water exposure, i 5.2 Variation in results may be expected when operating "nditions are varied within the accepted limits of this ractice. Therefore, no reference shall be made to results rom use of this practice unless accompanied by a report "etailing the specific operating conditions in conformance :th Section 11. 5.3 Any report correlating results from use ofthis practice i results from a period of natural weathering shall specify in detail the conditions of natural exposure, since sunlight and jwater effects upon materials exposed to the weather will vary from year to year and also vary with location, latitude, time of year, temperature, proximity to water sources, etc.
N' 1--Practice G 7 lists the information required to describe a
particular condition of outdoor exposure.
5.4 Correlations established and reported in conformance with 5.2 and 5.3 shall not be extrapolated to other test conditions permitted by this practice, to other conditions of natural exposure, or to materials other than those tested.
6. Apparatus5
6.1 Test Chamber, (see Fig. 2) constructed of corrosionresistant materials enclosing eight fluorescent UV lamps, a heated water pan, test specimen racks, and provisions for controlling and indicating operating times and temperatures.
6.2 Lamps, rapid start, medium bipin fluorescent UV lamps with a length of 1220 mm, and a nominal rating of 40 W when operated from a ballast providing a controlled current of 430 mA at 102V.
6.2.1 Unless otherwise specified, the lamps shall be UV-B lamps with a peak emission at 313 nm and a spectral energy distribution as shown in Fig. 1.
6.2.2 Other fluorescent UV lamps meeting the size and electrical characteristics in 6.2 may be used, provided that the lamp and spectraf energy' distribution are reported in conformance with Section 11.
6.3 Lamp Spacing and Arrangement--The lamps shall be mounted in two banks of four lamps each as shown in Fig. 2. The lamps in each bank shall be mounted parallel in a flat plane on 70-mm centers.
6.4 Specimen Mounting and Arrangement--The test spec imens shall be mounted in stationary racks with the plane of the test surface parallel to the plane ofthe lamps at a distance of 50 mm from the nearest surface ofthe lamps, as shown in Fig. 2.
6.4.1 The test specimens shall be exposed within an area 210 mm in height by 900 mm wide on each side of the apparatus located as shown in Fig. 4.
N' 2--It is possible to mount specimens above, below, and beside
the 210 by 900 mm area, but specimens so mounted will be exposed to lower UV intensities.
6.5 Condensation Mechanism--Water vapor shall be gen erated by heating a water pan extending under the entire sample area and containing a minimum water depth of 25 mm. Specimen racks and the test specimens themselves shall constitute the side walls of the chamber. The back side of the

specimens shall be exposed to cooling effects of ambient room air. The resulting heat transfer causes water to con dense on the test surface.
6.5.1 The specimens shall be arranged so that condensate runs off the test surface by gravity and is replaced by fresh condensate in a continuous process. Vents along the bottom of the test chamber shall be provided to permit an exchange of ambient air and water vapor to prevent oxygen depletion of the condensate.
6.6 Water Supply, with an automatic control to regulate the level in the water pan shall be provided. Distilled, deionized, or potable tap water are equally acceptable for purpose? of the test, since the condensation process itself distills water onto the test surface.
6.7 Cycle Timer, a continuously operating cycle time, for programming the selected cycle of UV periods and conden sation periods.
6.7.1 Hour meters shall be provided to record total time of operation and total time of UV exposure.
6.8 Specimen Temperature Measurement: 6.8.1 Specimen temperature shall be.measured by a ther mometer with a remote sensor attached to a black aluminum panel 75 by 100 by 2.5 mm thick. The thermometer shall be precise to 1C through a range from 30 to 80C. The indicator dial shall be located outside the test chamber. 6.8.2 The black aluminum panel with the thermometer sensor shall be positioned in the center of the exposure area so that the sensor is subject to the same conditions as the specimens. 6.9 Specimen Temperature Control: 6.9.1 During UV exposure, the selected equilibrium tem perature shall be maintained within 3C by supplying heated air to the test chamber. 6.9.2 During condensation exposure, the selected equilib rium temperature shall be maintained within 3C by heating the water in the water pan. 6.9.3 The UV and condensation temperature controls shall be independent of each other. 6.9.4 Doors shall be located on the room air side of the specimen racks to act as insulation during the UV exposure and to minimize drafts. Such doors shall not interfere with the room air cooling of the specimen during the condensa tion exposure. 6.10 Test Chamber Location: 6.10.1 The apparatus shall be located in an area main tained at a temperature between 20C and 30C. The room temperature shall be measured by thermometers mounted on interior walls or column approximately 1500 mm above the floor level and at least 300 mm from any heated apparatus, Three or more thermometers located at various points will show any temperature variation in the area. 6.10.2 It is recommended that the apparatus be located at least 300 mm from walls or other apparatus. Nearby heat
sources, such as ovens or heated test apparatus, should be
avoided or shielded, because such heat sources can reduce the cooling required for condensation.
6.10.3 The room where the apparatus is located, shall be
ventilated to remove, the heat and moisture produced and to
maintain the temperatures specified in 6.10.1. Two to four a;r

7. Test Specimens
.7,1 Replicate specimens are desirable to provide a record,
of degradation at different tiipe intervals. Retention of an
unexposed specimen is recommended as it is difficult to.
mask a specimen to prevent exposure to .condensation.
7.2 For specimens of insulating materials, ,such a^.wood;
plastic, m porous laminates, maximum specimen thickness
should be 20 mm to allow adequate heat transfer, fpr
condensation.
7.3 To provide rigidity, flexible specimens may be at
tached to a backing panel made of aluminum or other
noncorrosive heat conductive material.
7.4 Gut edges of coated steel specimens shall be protected
so that bust does not contaminate the test surface.
7.5 Holes in specimens and any openings larger than 1
mm around irregularly shaped specimens shall be sealed to
prevent loss of water vapor. Porous specimens, such as
textiles or wood shall be backed with a vapor barrier such as
metal or plastic.'
8. Calibration and Standardization
8.1 The thermometer or thermocouple which indicate?
test temperature shall be calibrated by immersing the sensing
element and a liquid-in-glass thermometer in water heated to
approximately 70C and cofnparing the two temperatures as
in Method E220.
'
''
8.2 The formation of'condeilsation may be observed by
using clear glass or plastic blanks in the specimen holders or
rack. One large sheet of plastic may also be' used for this
purpose. The condensate that forms on a ,given area during a
period of condensation may be collected and then, measured.
8.3 The fading and other changes caused by the fluores
cent UV lamps may be observed by exposing li'ghtfastneSS
standards in'the apparatus using UV alone without conden
sation.
'
8.3.1 The AATCC Blue'Wool Lightfastness reference
materials6 may be used to measure the changes caused by
UV. The L2 Blue Wool has been found satisfactory for
evaluating fluorescent UV lamps.
, 8,3.2 Other lightfastness reference -materials may be used
by agreement.
8.4 Reference standards for calibrating the operation of
the apparatus in alternate exposure to UV light and conden
sation may be prepared from painted metal, plastics, or other
materials. Painted metal specimens produced by the coil-
coating process have been found suitable for such reference
standards.

test surfaces facing the lamp. When the test specimens do completely fill the racks, fill the empty spaces with blank iels to maintain the test conditions within the chamber. p.2 Program the selected test conditions. Operate contin|usly, repeating the cycle, except for servicing the instru ct and inspection of specimens. t3 Various test conditions may be used. If no conditions jp specified, the following cycle and temperatures are Sgested: 4 h UV at 60C, 4 h Condensation at 50C.
|N' 3--Prior versions of this practice recommended a condensa-
|n temperature of 40'C in 9.3. When operating in room conditions |at do not comply with those set forth in 6.10, a 40"C condensation
iperature can result in inadequate condensation. Therefore, a 50"C |ndensation temperature is now suggested.
9.3.1 Any test temperature that can be maintained within ie limits specified in 6.9.1 and 6.9.2 may be used. UV test
iperature of 50C, 60C, and 70C are widely used. A fjbndensation test temperature of 50C is commonly used.
9.3.2 The Following time cycles are widely used: 4 h UV/4 CON, and"8 h UV/4 hr CON. Use UV and condensation leriods of at least 2-h duration to allow sufficient time to :ach equilibrium. 9.3.3 The severity of the UV exposure is influenced by test imperatures and time cycles. Photochemical reaction begins is soon as the UV lamps are turned on. The rate of UV degradation is proportional to the time of UV exposure or ie temperature of UV exposure, or both. UV exposures at jemperatures higher than those expected in the service mvironment can cause abnormal thermal degradation. 9.3.4 Water reactions during condensation exposure are iffected by the permeability of the specimen and require time to initiate.The rate of water degradation is increased by increased temperature. However, long hot condensation ixposures can cause abnormal degradation. Four-hour conlensation exposures are often used for paints on metals, hile condensation exposures of 20 h duration may be used [on wood.
9.4 Maintenance--Periodic maintenance is required to maintain uniform UV and condensation exposure condi
tions. 9.4.1 After 400 to 450 h of lamp operating time, replace
one lamp in each bank of lamps, and rotate the other lamps
as shown in Fig. 3. This procedure provides a useful lamp life of 1600 to 1800 h.
9.4.2 Drain water and clean water pan when conducting lamp replacement and rotation procedure. Scum on the top of the water can inhibit water vaporization.
9.5 Sample Rotation--The samples' positions within the test area should be rotated on a regular basis in order to
minimize any effects from horizontal or vertical variations in UV or temperature. The sample rotation sequence should provide that all samples spend approximately the same amount of exposure time near the center of the exposure area and near the edges of the exposure area. The following rotation sequence is recommended:
9.5.1 Horizontal Rotation--Once a day rotate the ex treme left hand and extreme right hand samples into the center as shown in Fig. 6.
9.5.2 Vertical Rotation--Rotate the samples vertically so that each sample spends the same amount of exposure time in each vertical position in the sample holder. For instance, if two samples are stacked vertically in each sample holder,
then the top and bottom sample should switch places halfway through the test method. If four samples are stacked vertically, then the samples should be repositioned vertically three times during the test method.
9.5.3 Other sample rotation sequences may be used by agreement.
9.6 Inspect specimens daily in tests with a length of 1 week or less. Tests for longer periods should be inspected weekly.
9.6.1 A permanent record of degradation at various times
may be obtained by using three replicate specimens and

removing the replicates sequentially at intervals equal to one third of the test length.
9.7 Conclude the test when either a mutually agreed-upon number of total test hours or a mutually agreed-upon change has occurred in the test specimen or a standard test spec imen. For convenience in inspecting and concluding tests during normal working hours, the following test durations are recommended:
96 h -- 4 days 168 h = 1 week 336 h = 2 weeks 504 h = .3 weeks
672 h = 4 weeks
1008 h 6 weeks 1512 h * 9 weeks 2016 h 12 weeks
10. Interpretation of Results
10.1 This practice is intended to simulate the deteriora tion caused by natural weathering. However, the rate of degradation in natural weathering varies from year to year. Laboratory accelerated weathering is more consistent in rate. Therefore, in comparing natural and laboratory weathering one should not attempt to predict the number of hours of laboratory exposure that might equal a year of natural weathering. Even if the details of the natural exposure are fully reported as required by 5.3, any time to time compar ison would apply only to a given year at a particular site.
10.2 It is possible to correlate the deterioration resulting from a period of natural weathering, such as 1 year, to the deterioration resulting from a period of laboratory acceler ated weathering. Spearman rank correlation, which is dis- '
cussed in most basic statistical texts, has proved to be a] useful method for this. A minimum of seven variables must i be ranked by both test methods to obtain statistical validity}, from Spearman rank correlation. Ranking 10 to 15 variables :' by both methods will improve the reliability of such correla-, tions.
10.3 It is frequently not possible to predict how many hours or weeks of accelerated testing will yield the best correlation to some period of outdoor testing. Therefore, laboratory tests should be measured periodically, such as weekly or biweekly, so that the correlation coefficient may be-,' calculated at several points during the accelerated test.

1. Scope
1.1 This standard gives guidance for application of The International System of Units (the modernized metric system) developed and maintained by the General Confer ence on Weights and Measures (abbreviated CGPM from the official French name Conference Generate des Poids et Mesures). The name International System of Units and the international abbreviation SI2 were adopted by the 11th CGPM in 1960.
1.2 Information is included on SI, a limited list of non-SI units recognized for use with SI units, and a list of conver sion factors from non-SI to SI units, together with generalguidance on proper style and usage.
1.3 It is hoped that an understanding of the system and its characteristics, and careful use according to this standard,
1 This standard is under the jurisdiction of ASTM Committee E-43 on Metric Practice and is the direct responsibility of Subcommittee E43.10 on Standards.
Current edition approved Oct. 3, 1991. Published December 1991. Originally published in 1964 without designation as ASTM Metric Practice Guide, revised 1966. Adopted as standard 1968. Last previous edition E 380 - 89.

will help to avoid the degradation that has occurred in all older measurement systems.
2. SI Units and Symbols__
2.1 Classes of Units--SI units are divided into three classes:
base units supplementary units derived units
2.2 Base Units--SI is based on seven well-defined units (see Table 1) which by convention are regarded as dimen sionally independent.
2.3 Supplementary Units--This class contains two units, the radian and the steradian (see Table 2). At the time of the introduction of the International System, the 11th CGPM left open the question of the nature of these supplementary units. Considering that plane angle is generally expressed as the ratio between two lengths and solid angle as the ratio between an area and the square of length, the CIPM (1980) specified that in the International System the quantities plane angle and solid angle should be considered as dimen-

sionless derived quantities. Therefore, the supplementary units radian and steradian are to be regarded as dimension less derived units which may be used or omitted in the expressions for derived units.
2.4 Derived Units: 2.4.1 Derived units are formed by combining base units, supplementary units, and other derived units according to the algebraic relations linking the corresponding quantities.
The symbols for derived units are obtained by means of the mathematical signs for multiplication, division, and use of exponents. For example, the SI unit for velocity is the metre per second (m/s or m s-1), and that for angular velocity is
the radian per second (rad/s or rad-s_!). 2.4.2 Those derived SI units which have special names
and symbols approved by the CGFM are listed in Table 3. 2.4.3 It is frequently advantageous to express derived
units in terms of other derived units with special names; for example, the SI unit for electric dipole moment is usually expressed as C-m instead of A-s-m.
2.4.4 Some common derived units are listed in Table 4. 2.5 SI Prefixes (see 3.2 for application): 2.5.1 The prefixes and symbols listed in Table 5 are used to form names and symbols of the decimal multiples and submultiples of the SI units except for kilogram. 2.5.2 Unit ofMass--Among the base and derived units of SI, the unit of mass (kilogram) is the only one whose name, for historical reasons, contains a prefix. Names of decimal multiples and submultiples of the unit of mass are formed by attaching prefixes to the word gram (g). 2.5.3 These prefixes or their symbols are directly attached to names or symbols of units, forming multiples and submultiples of the units. In strict terms these must be called "multiples and submultiples of SI units," particularly in discussing the coherence of the system (see Section 5). In common parlance, the base units and derived units, along with their multiples and submultiples, are all called SI units.
3. Application of the Metric System
3.1 General--SI is the form of the metric system that is preferred for all applications. It is important that this modernized form of the metric system be thoroughly under-

3.2.2 Selection--When expressing a quantity by a numer
ical value and a unit, a prefix should preferably be chosen soj that the numerical value lies between 0.1 and 1000. To! 3,2.4 Comp. minimize variety, it is recommended that prefixes repre \ the juxtapjii, senting 1000 raised to an integral power be used. However, ed. For exajy
three factors may justify deviation from the above:
3.2.2.1 In expressing area and volume, the prefixes hecto-,

hectometre, cubic centimetre. 3.2.2.2 In tables of values of the same quantity, or in a
discussion of such values within a given context, it is generally preferable to use the same unit multiple through out.

[measurements and clothing sizes. ! 3.2.3 Prefixes in Compound Units4--It is recommended
that only one prefix be used in forming a multiple of a
compound unit. Normally the prefix should be attached to a
unit in the numerator. One exception to this is when the
[kilogram occurs in the denominator.
Examples:
ro
.V/m, not mV/mm, and MJ/kg, not kJ/g
0 3.2.4Compound Prefixes--Compound prefixes, formed
'by the juxtaposition of two or more SI prefixes are not to be
[used. For example, use
1 nm, not 1 mpm I pF, not 1 (ipF
I lf values are required outside the range covered by the prefixes, they should be expressed by using powers of ten i applied to the base unit. j 3.2.5 Powers of Units--An exponent attached to a symbol : containing a prefix indicates that the multiple or submultiple {of the unit (the unit with its prefix) is raised to the power [ expressed by the exponent. For example:
4 A compound unit is a derived unit that is expressed in terms of two or more units rather than by a single special name.
l.cm3 = (10 2 m)3 1 ns"1 =(10-9s>-1 I mm2/s = (10~3 m)~/s
= 10~6 m3 = 109 s-1 = 1(T6 m2/s
3.2.6 Calculations--Errors in calculations can be mini mized if the base and the coherent derived SI units are"used and the resulting numerical values are expressed in powersof-ten notation instead of using prefixes.
3.3Other Units: 3.3.1 Units from Different Systems--To assist in pre serving the advantage of SI as a coherent system, it is advisable to minimize the use with it of units from other systems. Such use should be limited to units listed in this section.
3.3.2 Units in Use with SI (see Table 6): 3.3.2.1 Time--The SI unit oftime is the second. This unit is preferred and should be used if practical, particularly when technical calculations are involved. In cases where time relates to life customs or calendar cycles, the minute, hour, day, and other calendar units may be necessary. For ex ample, vehicle speed will normally be expressed in kilometres per hour. 3.3.2.2 Plane Angle--The SI unit for plane angle is the radian. Use of the degree and its decimal submultiples is permissible when the radian is not a convenient unit. Use of

the minute and second is discouraged except for special fields such as, cartography.
3.3.X3 Area--The SI unit of area is the square metre (m2). The hectare (ha) is a special name for square hectometre (hm2). Large land or water areas are generally expressed in hectares or in square kilometres (km2).
3.3.2.4 Volume--The SI unit of volume is the cubic metre. This unit, or one of the regularly formed multiples such as the cubic centimetre, is preferred. The special name litre' (L)6 has been approved for the cubic decimetre, but use of this unit is restricted to volumetric capacity, dry measure,, and measure of fluids (both gases and liquids). No prefix other than milli- or micro- should be used with litre.
3.3.2.5 Mass--The SI unit of mass is the kilograrn. This unit, or one of the multiples formed by attaching an SI prefix to gram (g), is preferred for all applications. The megagram (Mg) is the appropriate unit for measuring large masses such as have been expressed in tons. However, the name ton has been given to several large mass units that are widely used in commerce and technology--the long ton of 2240 lb, the short ton of 2000 lb, and metric ton of 1000 kg (also called the tonne). None of these terms are SI. The term metric ton should be restricted to commercial usage, and no prefixes should be used with it. Use of the term tonne is deprecated.
5 See Appendix XI. 11.1.

6 The CCJPM in October 1979 approved L and I as alternative symbols for litre.
Since the letter symbol 1 can easily be confused with the numeral 1, only the
symbol L is recommended for USA use.

3.3.3 Units in Use with SI Temporarily (see Table 7); 3.3.3.1 Energy--The SI unit of energy, the joule, together with its multiples, is preferred for all applications. The kilowatthour is widely used, however, as a measure of electric energy. This unit should not be introduced into any new areas, and eventually it should be replaced by the megajoule.
3.3.3.2 Pressure and Stress--The SI unit of pressure and stress is the pascal (newton per square metre) and with proper SI prefixes is applicable to all such measurements. Old metric gravitational units for pressure and stress such as kilogram-force per square centimetre (kgf/cm2) shall not be
used. Widespread use has been made of other* non-SI units such as bar and torr for pressure, but this use is strongly
discouraged. The millibar is widely used in meteorology; this usage will continue for the present in order to permit meteorologists to communicate easily within their profes sion. The kilopascal should be used in presenting meteoro logical data to the public.
3.3.4 Units and Names to Be Abandoned--A great many metric units other than those of the SI have been defined over the years. Some of these are used only in special fields; others have found broad application in countries that adopted the metric system early. Except for the special cases discussed in the previous sections, non-SI units (as well as special names for multiples or submultiples of SI units) are to be avoided. Various categories of deprecated units are discussed in 3.3.4.1 to 3.3AA. The lists are not intended to be complete, but only to indicate more or less prominent examples of each category.
3.3.4.1 Cgs Units--All units peculiar to the various cgs systems (measurement systems constructed by using the centimetre, gram, and second as base units) are to be avoided. Among these units are the following, defined for mechanics, fluid mechanics, and photometry, the erg, dyne, gal, poise, stokes, stilb, phot, and lambert. Further use of the cgs units of electricity and magnetism is deprecated. This statement applies to the units designated by the general abbreviations "esu" (for electrostatic cgs unit) and "emu" (for electromagnetic cgs unit), including those units that have been given special names--the gauss, oersted, maxwell, gilbert, biot, and franklin. It also applies to the unit names formed with the prefixes.-ab- and `Stat-, for example, the abampere, statvolt, etc.
3.3.4.2 Decimal Multiples of SI Units--Those multiples of SI units that cannot be handled by using the SI prefixes are deprecated. Many such examples are covered in subsection 3.3.4.1. An additional example is the angstrom (0.1 nm).

3.4 Other Recommendations Concerning Units: 3.4.1 Mass, Force, and Weight:
3.4.1.1 The principal departure of SI from the gravimetric system of metric engineering units is the use of explicitly distinct units for mass and force. In SI, the name kilogram is restricted to the unit of mass, and the kilogram-force (from which the suffix force was "in practice often erroneously dropped) should not be used. In its place the SI unit of force, the newton, is used (see Fig. 1). Likewise, the newton rather
than the kilogram-force isused to form derived units which include force, for example, pressure or stress (N/m2 = Pa), energy (N m = J), and power (N m/s = W).
3.4.1.2 Considerable confusion exists in the use of the term weight as a quantity to mean either force or mass. In commercial and everyday use, the term weight nearly always means mass; thus, when one speaks of a person's weight, the quantity referred to is mass. This nontechnical use of the term weight in everyday life will probably persist. In science
and technology, the term weight ofa body has usually meant
les ire on
mass 1 kg Moon
mass i 1kg i
Earth

|i.., I

DUP050298288
E 380
the force that, if applied to the body, would give it an acceleration equal to the local acceleration of free fall. The adjective "local" in the phrase "local acceleration of free fall" has usually meant a location on the surface of the earth; in this context the "local acceleration of free fall" has the symbol g (commonly referred to as "acceleration of gravity") with observed values of g differing by over 0.5 % at various points on the earth's surface. The use offorce ofgravity (mass times acceleration of gravity) instead of weight with this meaning is recommended. Because of the dual use of the term weight as a quantity, this term should be avoided in technical practice except under circumstances in which its meaning is completely clear. When the term is used, it is important to know whether mass or force is intended and to use SI units properly as described in 3.4.1.1, by using kilograms for mass or newtons for force.
3.4.1.3 Gravity is involved in determining mass with a balance or scale. When a standard mass is used to balance the measured mass, the effects of gravity on the two masses are equalized, but the effects, of the buoyancy of air. or other fluid on the two masses are generally not equalized. When a spring scale is used, the scale reading is directly related to the force of gravity. Spring scales graduated in mass units may be properly used if both the variation in acceleration of gravity and the buoyancy corrections are not significant in their use.
3.4.1.4 The use of the same name for units of force and mass causes confusion. When the non-SI units are used, a distinction should be made between force and mass, for example, Ibf to denote force in gravimetric engineering units and lb for mass.
3.4.1.5 The term load means either mass or force, de pending on its use. A load that produces a vertically downward force because of the influence of gravity acting on a mass may be expressed in mass units. Any other load is expressed in force units.
3.4.2 Temperature--The SI unit of thermodynamic tem perature is the kelvin (K), and this unit is properly used for expressing thermodynamic temperature and temperature intervals. Wide use is also made of the degree Celsius (C), which js the SI unit used for expressing Celsius temperature and temperature intervals. The Celsius scale (formerly called centigrade) is related directly to thermodynamic temperature (kelvins) as follows:
The temperature interval one degree Celsius equals one kelvin exactly. Celsius temperature (t) is related to thermodynamic tem perature (7) by the equation:
t=T-T0
where T0 = 273.15 K by definition.
The International Practical Temperature Scale (IPTS) must be recognized in temperature work of extreme precision. See ASTM STP 565, Evolution of the International Practical
Temperature Scale of 1968. 3.4.3 Linear Dimensions: 3.4.3.1 Nominal dimensions name the item; no SI equiv
alent is required (see Section 5 for definition of "nominal value"). For example, there is nothing "I in" about a nominal "1-in pipe," the dimensions of which should be converted as follows:
Nominal Size, inches

Both gage pressure and absolute pressure are properly expressed in pascals, using SI prefixes as appropriate. Abso lute pressure is never negative. Gage pressure is positive if above ambient pressure and negative if below. Pressure below ambient is often called vacuum; whenever the term vacuum is applied to a numerical measure it should be made clear whether negative gage pressure or absolute pressure is meant.

Handling of unit names varies because of In anguage differences, but use of the rules included here will be bnprove communications in the United States. ion 3.5.1 Rules for Writing Unit Symbols:
) ih
3.5.1.1 Unit .symbols should be printed in upright type Regardless of the type style used in the surrounding text.
3SN 3.5.! .2 Unit symbols are unaltered in the plural. is 3.5.1.3 Unit symbols are not followed by a period except rhen used at the end of a sentence.
is 3.5.1.4 Letter unit symbols are written in lower-case (for SI ixample, cd) unless the unit name has been derived from a lai roper name, in which case the first letter of the symbol is
i2) apitalized (for example, W, Pa). The exception is the Symbol for litre, L. Prefix symbols use either lower-case or
pper-case letters as shown in 2.5.1. Symbols retain their
prescribed form regardless of the surrounding typography.
es "or symbols for use in systems with limited character sets,
refer to ANSI X3.50 or ANSI/IEEE 260, as applicable. The
15 symbols in ANSI X3.50 are intended for applications in the SI' field of information processing, where unambiguous trans
mission of information between computers is required. The
[symbols in ANSI/IEEE 260 are generally consistent with
those in ANSI X3.50 and are intended for communication
between human beings. The symbols for limited character
(sets must ..never be used when the available character set
[permits the use of the proper general-use symbols as given in
ithis standard.
3.5.1.5 When a quantity is expressed as a numerical value
nd a unit symbol, a space should be left between them. For
(example, use 35 mm, not 35mm, and 2.37 1m (for 2.37
[lumens), not 2.371m.
Exception: No space is left between the numerical value
and the symbols for degree, minute, and second of plane
angle, and degree Celsius. For example, use 45, 20C.
3.5.1.6 When a quantity expressed as a number and a unit
is used in an adjectival sense, it is preferable to use a hyphen
instead of a space between the number and the unit name or
between the number and the symbol. Examples: A three-
metre pole. .. The length is 3 m. .. A 35-mm film... The
width is 35 mm. However, per 3.5.1.5 Exception, a 90
angle... an angle of 90.
3.5.1.7 No space is used between the prefix and unit
symbols.
3.5.1.8 Symbols, not abbreviations, should be used for units. For example, use "A" and not "amp" for ampere.
3.5.2 Rules for Writing Names:
3.5.2.1 Spelled-out unit names are treated as common nouns in English. Thus, the first letter of a unit name is not capitalized except at the beginning of a sentence or in capitalized material such as a title.
3.5.2.2 Plurals are used when required by the rules of English grammar and are normally formed regularly, for example, henries for the plural of henry. The following irregular plurals are recommended:
Singular
' Plural
lux hertz siemens
lux hertz siemens
3.5.2.3 No space or hyphen is used between the prefix and unit name. There are three cases where the final vowel in the prefix is commonly omitted: megohm, kilokfn, and hectare. In all other cases where the .unit name begins with a vowel both vowels are retained and both are pronounced.
3.5.3 Units Formed by Multiplication and Division: 3.5.3.1 With unit names:
Product, use a space (preferred) or hyphen:
newton metre or newton-metre
In the case of the watt hour the space may be omitted, thus:
watthour
Quotient, use the word per and not a solidus:
metre per second, not metre/second
Powers, use the modifier squared or cubed placed after the unit name:
metre per second squared
In the case of area or volume, the modifier may be placed before the unit name:
square millimetre, cubic metre
This alternative is also allowed for derived units that include area or volume:
watt per square metre N+,' --To avoid ambiguity in complicated expressions, symbols are preferred over words.
3.5.3.2 With unit symbols: Product, use a raised dot:
N m for newton metre
In the case of W-h, the dot may be omitted, thus:
Wh
An exception to this practice is made for computer print outs, automatic typewriter work, etc., where the raised dot is not possible, and a dot on the line may be used.
Quotient, use one of the following forms:
m/,s or m-s-l' or --ui
In no case should more than one solidus be used in the same
1113
DUP050298290
E 380
expression unless parentheses are inserted to avoid ambi guity. For example, write:
J/(mo! K) or J mol~1 K~' or (J/mol)/K,
but not
J/mol/K
3.5.33 Symbols and unit names should not be mixed in the same expression. Write:
joules per kilogram or J/kg or J - kg"'
but not
joules/kilogram nor joules/kg nor joules-kg-1
3.5.4 Numbers: 3.5.4.1 The recommended decimal marker is a dot on the line. When writing numbers less than one, a zero should be written before the decimal marker. 3.5.4.2 Outside the United States, the comma is often used as a decimal marker. In some applications, therefore, the common practice in the United States of using the comma to separate digits into groups of three (as in 23,478) may cause ambiguity. To avoid this potential source of confusion, recommended international practice calls for separating the digits into groups of three, counting from the decimal point toward the left and the right, and using a small space to separate the groups. In numbers of four digits on either side of the decimal point the space is usually not necessary, except for uniformity in tables. Examples:
' 2.141 596 73 722 7372 0.1335
Where this practice is followed, the space should be narrow (approximately the width of the letter "i"), and the width of the space should be constant even if, as is often the case in printing, variable-width spacing is used between words. Exceptions: In certain specialized applications, such as engineering drawings and financial statements, the practice of using a space for a separator is not customary.
3.5.4.3 Because billion means a thousand million (prefix giga) in the United Slates but a million million (prefix tern) in most other countries, this term and others, such as trillion, should be avoided in technical writing.
3.5.4.4 Use of M to indicate thousands, as in MCF for thousands of cubic feet, or in MCM for.thousands of circular mils, of MM to indicate millions, of C to indicate hundreds, etc., is deprecated because of obvious conflicts with the SI prefixes.
3.5.5 Attachment--Attachment of letters to a unit symbol as a means of giving information about the nature of the quantity under consideration is incorrect. Thus MWe for "megawatts electrical (power)," Vac for "volts ac,'' and kJt for "kilojoules thermal (energy)" are not acceptable. For this reason, no attempt should be made to construct SI equiva lents of the abbreviations "psia" and "psig," so often used to distinguish between absolute and gage pressure. If the context leaves any doubt as to which is meant, the word pressure must be qualified appropriately. For example:
".,. at a gage pressure of 13 kPa"
or
"., . at an absolute pressure of 13 kPa"
Where space is limited, such as on gages, nameplates, graph labels, and in table headings, it is permissible to use the unit symbol followed by a space and the modifier in parentheses For example: V (ac) and V (die); kPa (gage) and kPa (absolute).
3.5.6 Pronunciation-Some recommended pronuncia tions in English are shown in Table 8.
4. Rules for-Conversion and Rounding
4.1 General:
4.1.1 Conversion factors to change a value of a quantity expressed in non-SI units to the corresponding value of that quantity expressed in the International System of Units may be exact or approximations adequate for the particular task. The rules in this section are based on using either exact or approximate factors such as those of seven-digit factors listed in Appendix X3. In some cases the quantity is such that factors with fewer digits are appropriate.
4.1.2 Conversion of quantities should be handled:with careful regard to tfie implied correspondence between the accuracy of the data and the given number of digits. In all conversions, the number of significant digits retained should be such that accuracy is neither sacrificed nor exaggerated. (For guidance concerning significant digits see 4.3.) For example, a length of 125 ft converts exactly to 38.1 m. If, however, the 125-ft length had been obtained by rounding to the nearest 5 ft, the conversion should be given as 38 m; and if it had been obtained by rounding to the nearest 25 ft, the conversion should be given as 40 m.
4.1.3 Proper conversion procedure is to multiply a value by a conversion factor that is more accurate than is required; the result is then rounded to the appropriate number of sig nificant digits. For example, to convert 3 feet 29/is inches to metres: (3 x 0.3048) + (2.5625 x 0.0254) = 0.979 487 5 m,' which rounds to 0.979 m. Do not round either the conver sion factor or the quantity before performing the multiplica tion, as accuracy may be reduced. After the conversion, the

SI value may be expressed by a multiple or submultiple unit of SI by the use of an appropriate prefix, for example, 979 mm.
4.2 Accuracy and Rounding--A conversion obtained by
multiplying a value by a seven-digit factor usually gives a product with more digits than the original value. The converted value must be rounded to the proper number of significant, digits commensurate with the intended accuracy. Conversions usually yield a product with more, digits than the original value. The practical aspect of measuring must be considered when using SI equivalents. If a scale having division of >/i6 inch was suitable for making the original measurements, a metric scale having divisions of 1 mm is obviously suitable for measuring in SI units, Similarly, a gage or caliper graduated in divisions of 0.02 mm is comparable to one graduated in divisions of 0.001 in. Analogous situations exist in mass, force, and other measurements. Many techniques are used to guide the determination of the proper number of significant digits in the converted values. Two different approaches tp rounding of quantities are here described-r-one for general use and the other for conversion of dimensions involving mechanical interchangeability.
4.2.1 General Conversion--This approach depends on
first establishing the intended precision or accuracy of the quantity as a necessary guide to the number of digits to retain. This precision, should relate to the number of digits in the original, but in many cases this is not a reliable indicator. A figure 1.1875 may be a very accurate decimalization of a noncritical l3/i6 that should have been expressed 1.19. On the other hand, the value 2 may mean "about 2," or it may mean a very accurate value, of 2 which should have been written 2.0000. It is therefore necessary to determine the intended precision of a quantity before converting. This estimate of intended precision should never be smaller than the accuracy of measurement and should usually be smaller
than one tenth the tolerance if one exists. After estimating the. precision of the dimension, the converted dimension should be rounded to a minimum number of significant digits (see 4.3) such that a unit of the last place is equal to or smaller than the converted precision. Examples:
1. A stirring rod 6 in. long. In this case, precision is estimated to be about 'h in ( `A in). Converted, this is 12.7
mm. The converted dimension 152.4 mm should be rounded to the nearest 10 mm, or 150 mm.
2. 50 000 lbf/in2 (psi-j tensile strength. In this case, precision is estimated, to be about 200 lbf/in2 ( 1.4 MPa) based on an accuracy of 0.25 % for the tensile tester and other factors. Therefore, the converted dimension, 344.7379 MPa, should be rounded to the nearest whole unit, 345,MPa.
3. Test pressure 200 15 lbf/in2 (psi). Since one tenth of the tolerance is 3 lbf/in2 (20.68 kPa), the converted dimen sion should be rounded to the nearest 10 kPa. Thus, 1378.9514 103.421 35 kPa becomes 1380 100 kPa.
4.2.2 Special Cases: 4.2.2,1 Converted values should be rounded to the min imum number of significant digits that will maintain the required accuracy, as discussed in 4.1.2. In certain cases deviation from this practice to make use of convenient or whole numbers may be feasible, in which case the word "approximate" must be used following the conversion. For example:
l'/a ia = 47.62$ nrm^exact 47.6 mm .normal rounding s 47.5 mm (approx) rcsunded to preferred nu|| 48 mm (approx) rounded to whole number!
4.2.2.2 A quantity stated as a limit, such as
than" or "maximum," must be handled so that f
limit is not violated. For example, a specimen "all
wide" requires a width of at least 101.6 mm, or atf
mm. `
4.3 Significant Digits:
4.3.1 When converting integral values of units, i
ation must be given to the implied or required pr||
the integral value to he converted. For example, the
in" may be intended to represent 4, 4.0, 4.00,
4.0000 in, or even greater accuracy. Obviously, the t
value must be carried to a sufficient number off
maintain the accuracy implied or required in the
quantity.
4.3.2 Any digit that is necessary to define the)
value or quantity is said to be significant. When mea
the nearest 1 m, a distance may be recorded as 15*1
number has three significant digits. If the measuren
been made to the nearest 0.1 m, the distance may Mi
157.4 m; this number has four significant digits.
4.3.3 Zeros may be used either to indicate a specif
like any other digit, or to indicate the order of magnf
a number. The 1970 United States population!,
rounded to thousands was 203 185 000. The six lri
digits of this number are significant; each measure's \
The three right-hand digits are zeros which merely '
the order of magnitude of the number rounded to the'
thousand. The identification of significant digits

ample, the number 1000 may be-rounded from "
which case only one zero is significant, or it may be i.
from 999.7, in which case all three zeros are signifid

traded, multiplied, or divided..__

The total is then rounded to 477 000 000 as called for by the rule. Note that if the second of the figures to be added had been 217 985 000, the rounding before addition would have produced 218 000 000, in which case the 0 following 218 would have been a significant digit.
4.3.4.2 The rule for multiplication and division is that the product or quotient shall contain no more significant digits than are contained in the number with the fewest significant digits used in the multiplication or division. The difference between this rule and the rule for addition and subtraction should be noted; the latter rule merely requires rounding of digits that lie to the right of the last significant digit in the least precise number. The following illustration highlights this difference:
Multiplication: 113.2 x 1.43 = 161.876, rounded to 162
Division: 113.2 + 1.43 - 79.16, rounded to 79.2
Addition.* 113.2 + 1.43 = 114.63, rounded to 114.6
Subtraction: 113.2 - 1.43 = 111.77, rounded to 111.8
The above product and quotient are limited to three signifi cant digits since 1.43 contains only three significant digits. In contrast, the rounded answers in the addition and subtrac tion examples contain four significant digits.
4.3.4.3 Numbers used in the above illustrations have all been estimates or measurements. Numbers that are exact counts are treated as though they consist of an infinite number of significant digits. More simply stated, when a count is used in computation with a measurement the number of significant digits in the answer is the same as the number of significant digits in the measurement. If a count of 40 is multiplied by a measurement of 10.2, the product is 408. However, if 40 were an estimate accurate only to the nearest 10, and hence contained but one significant digit, the product would be 400.
4.4 Rounding Values1-. 4.4.1 When a figure is to be rounded to fewer digits than the total number available, the procedure should be as follows: 4.4.2.1 When the first digit discarded is less than 5, the last digit retained should not be changed. For example, 3.463 25, if rounded to four digits, would be 3.463; if rounded to three digits, 3.46. 4.4.1.2 When the first digit discarded is greater than 5, or if it is a 5 followed by at least one digit other than 0, the last digit retained should be increased by one unit. For example 8.376 52, if rounded to four digits, would be 8.377; if rounded to three digits 8.38. 4.4.1.3 When the first digit discarded is exactly 5, followed only by zeros, the last digit retained should be rounded upward if it is an odd number, but no adjustment made if it
is an even number. For example, 4.365, when rounded to
three digits, becomes 4.36. The number 4.355 would also
round to the same value, 4.36, if rounded to three digits.
4.5 Conversion of Linear Dimensions of Interchangeable
Parts--The use of the exact relation 1 in = 25.4 mm
generally produces converted values containing more dec
imal places than are required for the desired accuracy. It is
therefore necessary to round these values suitably and at the
same time maintain the degree of accuracy in the converted
values compatible with that of the original values.
4.5.1 General--The number-of decimal places given in
Table 9 for rounding converted toleranced dimensions
relates the degree of accuracy to the size of the tolerances
specified. Two methods of using Table 9 are given: Method
A, which rounds to values nearest to each limit, and Method
B, which rounds to values always inside the limits.
In Method A, rounding is effected to the nearest rounded
value of the limit, so that, on the average, the convened;
tolerances remain statistically identical with the original
tolerances. The. limits converted by this method, where
acceptable for interchangeability, serve as a basis for inspec
tion.
In Method B, rounding is done systematically toward the
interior ofthe tolerance zone so that the converted tolerances
are never larger than the original tolerances. This method
must be employed when the original limits have to be
respected absolutely, in particular, when components made
to converted limits are to be inspected by means of origin af
gages.
Method A--The use of this method ensures that even in'.j
the most unfavorable cases neither of the two original limits
will be changed by more than 5 % of the value of the
tolerance. Proceed as follows:
(a) Calculate the maximum- and minimum limits in
inches.
(b) Convert the corresponding two values exactly inter!
millimetres by means of the conversion factor 1 in = 25.4'
mm.
(c) Round the results obtained to the nearest rounded
value as indicated in Table 9, depending on the original!
tolerance in inches, that is, on the difference between the two
limits in inches.
~ if -
Method B--This method~must be employed when the
original limits may not be violated, for instance, certain
critical mating parts. In extreme cases, this method naa.jf
increase the lower limit a maximum of 10 % of the tolerance'
and decrease the upper limit a maximum of 10 % of th e
tolerance.
(a) Proceed as in Method A step (a). lb) Proceed as in Method A step (b).
l c) Round each limit toward the interior of the tolerance,
that is, to the next lower value for the upper limit and to the
next higher value for the lower limit.8

4.5.2 Special Methodfor Dimensions with Plus and Minus Deviations--In order.'ta avoid accumulation of rounding (errors, the two limits.of size normally are converted sepa rately: thus, they must.first'be calculated if the dimension consists of a basicsi^e and two deviations.- However (except

when Method B is specified) as an alternative, the basic size may be, converted..to the nearest rounded value and each of | the deviations converted.towurd the interior of the tolerance. | This method, which sometimes makes conversion easier* gives the same maximum guarantee of accuracy as Method A, but usually results in smaller converted tolerances.

4.5.3 Special Methods for Limitation Imposed by Accu\ racy ofMeasurements--If the increment of rounding lor the ; tolerances given in Table 9 is too small for the available accuracy of measurement, limits that are acceptable for interchangeability must be determined separately for the dimensions. For example, where accuracy of measurement is limited to 0.001 mm, study shows that values converted

Position Dimension--If the toleranced dimension is located ; in a plane, the position of which is given by nontoleranced
ten the certain
id may lerance of the
basic- or gage dimension, such as when dimensioning certain conical surfaces, proceed as follows:
( ) Round the converted reference gage arbitrarily, to the
nearest convenient value. ( ) Calculate exactly, in the converted unit of measure
ment, new maximum and minimum limits of the specified
tolerance zone, in the new plane defined by the new basic
dimension.

(c) Round these limits in conformity with the rules in 4.4. For example, a cone of taper 0.05 in/in has a diameter of 1.000 0.002 inch in a reference plane located by the
nontoleranced dimension 0.9300 in. By virtue of the taper of
the cone, the limits of the tolerance zone depend on the
position of the reference plane. Consequently, if the dimen
.anged.
sion 0.9300 in = 23.6220 mm is rounded to 23.600 mm (that is, a reduction of 0.022 mm), each of the two original limits,
when converted exactly into millimetres, must be corrected
by 0.022 x 0.05 = 0.0011 mm, in the appropriate sense,
before being rounded.
4.5.6 Consideration ofMaximum and Minimum Material
Condition--The ability to assemble mating parts depends on
a "go" condition at the maximum material limits of the parts. The minimum material limits, which are determined by the respective tolerances, are- often not as critical from a functional standpoint. Accordingly, it may be desirable to emplby a combination of Methods A and B in certain conversions by using Method B for the maximum material limits and Method A for the minimum material limits. Alternatively, it may be desirable to round automatically the
(converted minimum material limits outside the original limits to provide greater tolerances for manufacturing.
4.5.7 While'the-technique described in 4,5 provides good accuracy of conversion, it will often result in dimensions that are impractical for actual production use. For conversions
intended for production, it is usually necessary to round to fewer decimal places and apply design judgment to each dimension to assure interchangeability.
4.6 Other`Units:
4.6.1 Temperature--General guidance for converting tol erances from degrees Fahrenheit to kelvins or degrees Celsius is given below:
Conversion of Temperature Tolerance Requirements
Tolerance, *F
Tolerance, K or C
2 (1) 4 (2) 10 (5) 20 (10)
30 (15) 40 (20)
50 (25)
1 (0,5)
2(1) 6 (3) 11 (5.5) 17 (8.5) 22 (11) 28 (+14)
Normally, temperatures expressed in a whole number of degrees Fahrenheit should be converted to the nearest 0.5 kelvin (or degree Celsius). As with other quantities, the number of significant digits to retain will depend upon implied accuracy of the original dimension, for example:
100 5F; implied accuracy estimated to be 2F. 37.7777 2.7777C rounds to 38 3"C. 1000 50F; implied accuracy estimated to be 20F.
537.7777 27.71TTC rounds to 540 30"C.'
4.6.2 Pressure or Stress--As with other quantities, pres sure or stress values may be converted by the principle-given above. Values with an uncertainty of more than 2 % may be converted without rounding by approximate factors:
1 lbf/in2 (1 psi) = 7 kN/m2 = 7 kPa

5.2 Certain terms used in this standard are defined as foUows:
accuracy (as distinguished from precision)--the degree of conformity of a measured or calculated value to some recognized standard or specified value. This concept involves the systematic error of an operation, which is seldom negligible.
approximate value--a value that is nearly but not exactly correct or accurate.
coherent system of units--a system of units of measure ment in which a small number of base units, defined as dimensionally independent, are used to derive all other units in the system by rules of multiplication and division with no numerical factors other than unity (see Appendix X1.9).
deviation--variation from a specified dimension or design requirement, usually defining upper and lower limits (see also tolerance).
digit--one of the ten arabic numerals (0 to 9). dimension--a geometric element in a design, such, as length" or angle, or the magnitude of such a quantity.
feature--an individual characteristic of a part, such as screw-thread, taper, or slot.
figure (numerical)--an arithmetic value expressed by one or more digits.
inch-poutid units--units based upon the yard and the
pound commonly used in the United States of America afiifci
defined by the National Institute of Standards and Tec.i-'i
nology. Note that units having the same names in other j
countries may differ in magnitude.
>
nominal value--a value assigned for the purpose of c on-
venient designation; existing in name only.
precision (as distinguished from accuracy)--the degree of j
mutual agreement between individual measurements;.,' namely repeatability and reproducibility.
significant digit--any digit that is necessary to define a
value or quantity (see-4.3).
tolerance--the total amount by which a quantity is;
allowed to vary; thus the tolerance is the algebraic difference
between the maximum and minimum limits.

Condensed Index of Committee D-l Standards--19921
This index references all standards under the jurisdiction of Committee D-i on Paint and Related Coatings and M ,
plus several others of auxiliary usefulness. It attempts to include what is relevant and exclude what is incidental to the cone nip
of each standard. Being designed for Committee D-I usage it omits much of the detailed information provided in the i i
more comprehensive index, the latter being intended for users with a broader range of product concern. It's structure employ
cross-indexing from specific to general and vice-versa, with the objective of avoiding redundancy while guiding the usci with-
dispatch to the desired and related material. The criterion for the selection of index terms is whether they might reasonablv
occur to an index user familiar with the technology of organic coatings. Index users encountering errors or other deficieruvs'
should report them promptly by writing to ASTM Subcommittee D01.18 in care of ASTM Headquarters. Changes will* be
included in the next edition along with entries for new 'standards. Subcommittee chairmen should review the standards under `
their jurisdiction for that purpose.
