Record these dry weights on the log sheet. U.b Place the rings in the viater tank. The water temperature should be 75 - 10F. Temperature of the room should be 75 1 10F. also. The rings must be allowed to soak (completely submerged in the water) between 8 and not more than 20 hours. Tnis includes either 1" or 2" wide rings of any wall thickness. If pieces or chunks of A/C material are to be tested, make certain the length is ten times the width of the piece regardless of the piece thickness. h.$ Weigh the A/C pieces in the water soak. Do not remove the pieces from the water soak until the submerged weight has been obtained. The submerged weight is determined by taring the balance while the suspending wire and hook are dangling in the water (at a depth which will insure complete submersion of the piece when it is placed on the hook). Place the A/C piece on the hook, bring the balance to equilibrium, making certain the A/C pieces and the wire or hook are not touching the bottom or sides of the water tank and check to see that the A/C piece is completely submerged. Enter weight in log sheet. Specimen surface should be free of air bubbles. U.6 Remove the' A/C pieces from the water tank and shake vigorously four times to remove excess water. Support the A/C piece at an angle of h$ to 60 on a rack to obtain maximum and uniform surface exposure. Keep the A/C pieces away from excessive drafts and do not allow them to be in contact with any absorbent surface. Weigh the pieces after $ minutes of draining on the rack, but not after more than 20 minutes. This is the saturated weight. Enter the weight in the log sheet.

Three specific plans are recognized: 1. Hand Sampling, 2. Trial Run Sampling and Standard Evaluation Sampling. Hand Sample A hand sample normally consists of not more than 5-10 pounds pf| fiber and is tested as a Fan-Opened material. In this method, the total "As Received" sample is spread out at a uniform thick ness on a surface sufficiently large to accommodate all of the material. It is then blended by overlaying scoopfuls to achieve a symmetrical cone which is subsequently quartered. After opposite Quarters have been combined and blended, the resultant halves are reworked together and gathered again into a cone. As a final step, jbis cone is quartered and each quarter placed in individual plastic bags for further processing. From the four samples, one of the samples is retained in the "As Received" state, while the remaining three are processed by Fan Opening under three different sets of conditions - 2, 3 and 5 passes at 100$ fan speed. The three degrees ofi opening achieved are comparable to the opening which would bt produced by willowing at 12, 2k and U8 hairpin configurations.V After pro cessing, the three samples are individually bagged and set aside with the "As Received" sample for testing. Trial Shipment Sample The trial shipment sample is representative of a 5 to 10 ton lot shipment of fiber. This shipment of fiber will normally be requested following a satisfactory appraisal of properties based upon the "Hand Sample" evaluation and is used for a trial run at the plant level. The making particulars for such a run are based upon the data established from a sample forwarded to R&D for evaluation. The sample selection from the 5 to 10 ton shipment is 3 bags randomly chosen from the lot. The three bags of fiber are carefully blended in accordance with a specified procedure and I KEQOt-.v"^ ^rOf*y V.-n io x :o f 3265 : inch xeao copy ; SHIPMENT A. 3 - Eags -I- l <==-.: jn n <mU:v n <> Li l: SHIPMENT:B. 3 -Bags 1 j i i `I Efefeti -| v-- II -U a^B-EhEf-- i FIBER SAMPLING PATTERN, I3<S#S3:Q:I3:: 'i;bb;: IIBSHIPMENT: Cl .'ZX3 Bags"I i '! ^pEEB3B; SftEFBBTTfi .L'l Qvj::B"!:B 01 l XERO ' iICOPt*I el ! _!

The procedure followed is in accordance with the 11 one shipment" handling of the fiber as discussed in the following section under "Standard Evaluation Sample" and set forth in Plate I. Three of the quarters from the composite lot are processed to varying degrees of openness by willowing at hairpin configurations of 12, 2U and h8 hairpins. The fourth quarter is retained in the "As Receiveo" condition. The four lots resulting from this division and processing serve as the basis for the evaluation program. Standard Evaluation Sample A standard evaluation program is periodically conducted on all fibers normally used in A/C pipe blends. In such a pro gram, samples are collected from three plants where the fiber under test is normally used as a regular component and is received in lot shipments ranging from 50 to several hundred tons per shipment. The sample selection for the test is made up of three bags of fiber randomly taken from a different lot shipment at each of the three plants. The nine bags of fiber are then sent to the Fiber Testing facility at the Research and . Development Center for processing and testing. The total "source sample" as received at R&D amounts to 900 to 1125 pounds of fiber depending upon whether the bag weights are 100 pounds as for Cassiar and Canadian Quebec fibers or 125 pounds as far the African Chrysotile and Blue fibers. This se lection of fiber, which is considered a representative composite of the fiber grade and quality originating from a given mine, is carefully blended, quartered, processed and sampled to yield working samples for laboratory investigation. Plate I shows the pattern for fiber blending and sample accumulation to be followed in preparing the source sample for willow processing and individual sample procurement. The three ----- bag lots received from each of the three plants are identified as Shipments A, B and C. In the first step, each individual shipment is blended and quartered to produce four sets of samples. The first set provides a 10 pound "As Received" sample, the second set a 75 pound sample for willowing at 2k hairpins, while the third and fourth sets provide two 75 pound samples of fiber which are set aside with similar samples (six in total) from the re maining two shipments. After collection of the six 75 pound samples (two from each shipment), they are blended and quartered s PTs --/ r? r CTD010135 -3- again to provide four 110 pour:d samples of blended composite for further processing. One of the quarters provides the composite "As Received" sample while the remaining three quarters are willow processed at 12, 2h and U8 hairpin con figurations respectively. Upon conclusion of these steps, the following samples : are available for test. 1. 3 - "As Received" Samples - 10 pounds for each shipment. 2. 3- Willoved Samples - 23 pounds for each shipment. 3. 1 - "As Received" Sample - 25 pounds composite ' - - U. 1 - Willoved - 12 Hairpin Composite - hO pounds. ....... 5- 1 - Willowed - 2h Hairpin Composite - iiO pounds. p- 6. 1 - Willowed - Li8 Hairpin Composite - 1*0 pounds. The surplus fiber resulting . rr.i each sampling operation is bagged, combining all of the "As Received" materials together and all of each of the separately mi'j lowed fibers according to -treatment. Each bag is properly labeled to identify the fiber, the grade and the extent of treatment if any. The total excess fiber is then placed in Plant 58 fiber storage for use at their discretion, i jCxoennbor ) CTD010136 I / ' APPENDIX B TEST METHODS USED TO EVALUATE ASBESTOS FIBERS The test methods that are used to determine the significant properties of asbestos fibers serve to establish the adaptability of a particular fiber as an A/C pipe blend component on the basis of a variety of inherent character istics. Each test has been devised and developed, in many cases, over a period of time often measured in years, to provide reliable and reproducible information related to one particular property or habit of a fiber. An evaluation and full analysis of a given fiber requires that the several individual property values obtained from each of the test procedures be considered as a composite of that fiber's capabilities. The reports offered in the main body of this presentation are such composite considerations. All of the test methods that are currently used exhibit a high degree of reproducibility and the infor mation resulting from a representative evaluation program is usually directly applicable to the definition of the performance capabilities of a fiber under study to pipe machine operation. The test methods here set forth include those that are now used in all evaluation studies and by means of which the data in the reports here presented was procured. In addition, however, for reference and historical purposes, certain test methods are also included that are not now used, but from which certain bits of useful data has been obtained in the past and to which some reference may still be made. It is not intended that a detailed working knowledge of each test is necessary to affect a proper analysis or understanding of the data related to each fiber as feere reported. Rather, the purpose is to establish and make a record of the specific methods followed at this time so that if, at some future date, a change or revision may be brought into being, this record will historically establish the validity of the current data and may well serve as a basis upon which data1 differences, induced by later procedural or apparatus changes, may be accounted for andjustified.
