I--History oi Standard On Sep. 10,1902, NEWWA adopted a "Standard Specification for CastIron Pipe and Special Castings," covering bell-and-spigot pit-cast pipe and fittings of ten thickness classes. The thickness classes were based on allowable internal pressures varying by increments of 50 ft of head. On May 12, 1908, AWWA adopted a "Standard Specification for CastIron Pipe and Special Castings," covering bell-and-spigot pit-cast pipe and fittings of eight classes, A through with allowable working pressures '^Varying by increments of 100 ft of head from 100 to 800 ft. Dimensions and weights were given for pipe and fittings. In 1926, ASA Sectional Committee O(now American National Standards Committee) A21 on Cast-Iron Pipe and Fittings was organized under the sponsorship of A.G.A., ASTM, AWWA, and NEWWA and was as signed the following scope: Unification of specifications for castiron pipe, including materials; dimen sions; pressure ratings; methods of manufacture (including such new de velopments as centrifugal casting) insofar as they may be necessary to secure satis factory specifications; elimination of un necessary sizes and varieties; consideratio l of the possibility of developing a coordinated scheme of metallic pipe and fittings applicable to all common me diums; and methods of making up joints ; nsofar as they are determining as to the ^`'dimensional design of cast-iron pipe. The types of cast-iron pipe [are] to include bell-and-spigot pipe, flanged pipe, flanged and bell mouth fittings and wall castings, pipe elbows, tees, wyes, return bends, and other fittings not now included in standard lists; cast-iron pipe threaded for flanges or couplings. The standardization is not to include methods of installing pipe and similar matters, except as to the making up of joints in its relationship to the dimensional stan dardization of pipe and fittings, as noted above. Sectional Committee A21 spon sored many tests of pipe and fittings; these included subjection of pipe to combined earth load and internal pressures (which form the basis of pipe thickness design), corrosion tests, measurement of hydraulic friction loss in fittings, and tests of bursting strengths of pipe and fittings. After exhaustive study of the test results and other research, the committee in 1939 issued A21.1, "American Stan dard Practice Manual for the Comp utation of Strength and Thickness of Cast Iron Pipe." The manual included nomograms and thickness tables for pit-cast pipe with 11/31* iron strength. As stated in the preface to that manual, however, the design method was applicable to pipe of any iron strength. Discussions and interpretations of the method of design of cast-iron pipe * The first figure designates the bursting tensile strength in units of 1 000 psi and the second figure designates the ring modulus of rupture in units of 1 000 psi. m CTD014648 were published in 1939 and presented to AWWA and A.G.A. As a result of these publications and because of the general acceptance of A21.1, a substantial volume of cast-iron pipe was designed by the new method and furnished to manufacturers' standards between 1939 and 1953. A standard (A21.2) for pit-cast pipe with 11/31 iron strength also was issued in 1939. Work on standards for centrifugally cast pipe with 18/40 iron strength was started after the design was completed in 1939, but, owing to the intervention of World War II and other causes, they were not formally issued until 1953. In 1957, a revision of A21.1 was issued. In that revision, designated ASA A21.1-1957 (AWWA Hl-57) the major change was the addition of a method for computing earth loads on pipe laid under embankments and of nomograms and thickness tables for centrifugally cast pipe with 18/40 iron strength. In 1958, Sectional Committee A21 was reorganized. Subcommittees were established to study each group of standards in accordance with the review and revision policy of ASA (pow ANSI). The subcommitteee on pipe (Subcommittee No. 1) was or ganized with the following assignment: The scope of the committee actitivy shall include an examination of all pres ent A21 standards for pipe to determine what is needed to bring these up to date. The examination shall include A21.1, A21.2, A21.3, A21.6, A21.7, A21.8, and A21.9, as well as any other matters per taining to pipe standards. As a result of the work of Subcom mittee No. 1 on this assignment, re visions of the cast-iron pipe standards A21.6(AWWA C106), A21.7, A21.8 (AWWA C108) and A21.9 were issued in 1962. A revision of A21.1-1957 (AWWA Hl-57) was issued in 1967 and reaffirmed without revision in 1972. Revisions of the 1962 cast-iront Ipipe standards were issued in 1970 The major revisions of A21.6-197C were: pipe with push-on joints wer added; laying conditions C and D were deleted and condition F was added; and, the tables were revised to include the pipe lengths then being produced. In 1974, Subcommittee 1 reviewed the 1970 edition and recommended minor editorial changes. Therefore, this edition is unchanged from the 1970 edition except for minor editorial changes and the updating of this fore word. The tables and strength test re quirements in this standard are for pipe with 18/40 iron strength. Ad vances in production technology have enabled the manufacturers to furnish pipe with greater strength. Pipe with 21/45 iron strength has been furnished for many years. Design details and standard thicknesses for^^ pipe with 21/45 iron strength are^^ shown in A21.1-1957 (AWWA C10167), reaffirmed in 1972. II--Acceptance Tests Acceptance tests were establishes as routine control measures to ensure^ the design burst and ring strengths. The acceptance tests specified in this standard are the Talbot strip test and the hardness test. In establishing the acceptance values for the Talbot strip test, A21 Committee in the 1940s re viewed detailed data, including burst, ring, and Talbot strip tests on more than 400 pipe centrifugally cast in metal molds. Correlations of the data showed that the Talbot strip modulus of rupture and secant modu lus of elasticity values specified in this standard represent acceptable pipe which meet the design burst and rin^^ strengths. IV CTD014649 The hardness test was specified as a means of assuring the ferritic matrix which is characteristic of the microstructure of pipe cast in metal'molds. The specified acceptance values for the Talbot strip test provide addi tional control of the microstructure to ensure satisfactory machinability. Ill--Options This standard includes certain options which, if desired, must be specified in the invitation for bids and on the purchase order. Also, a num ber of items must be specified to de scribe completely the pipe required. The following summarizes these de tails and available options and lists the sections of the standard where they can be found: 1. Size, joint type, thickness or class, and laying lengths (Tables) 2. Special joints (Sec. 6-1) 3. Certification by manufacturer (Sec. 6--1) 4. Inspection by purchaser (Sec. 6-5) 5. Cement lining (Sec. 6-8.2) Ex perience has indicated that bi tuminous inside coating is not complete protection against loss in pipe capacity caused by tuberculation. Cement linings are recommended for most waters. 6. Special coatings and linings (Sec. 6-8.4) 7. Special marking on pipe (Sec. 6-10) 8. Written transcripts of foundry records (Sec. 6-15) 9 Special tests (Sec 6-16). 0 o 0 CTD014650 Committee Personnel j Subcommittee 1, Pipe, which reviewed this standard, had the following per sonnel at that time: Edward C.

' I Such special coatings and linings shall he specified in the invitation for bids and on the purchase order. Sec. 6-9--Hydrostatic Test Each pipe shall be subjected to a hydrostatic test of not less than 500 psi. This test may be made either be fore or after the outside coating and the inside coating have been applied, but shall be made before the applica tion of cement lining or of a special lining. The pipe shall he under the full test pressure for at least 10 s. Suitable controls and recording devices shall be provided so that the test pressure and duration may be adequately ascer tained. Any pipe that leaks or does not withstand the test pressure shall be rejected. In addition to the hydrostatic test before application of a cement lining or special lining, the pipe may be re tested, at the manufacturer's option, after application of such lining. Sec. 6-10--Marking Pipe The weight, class or nominal thick ness, and sampling period shall be shown on each pipe. The manufac turer's mark and the year in which the pipe was produced shall be cast or stamped on the pipe. When specified on the purchase order, initials not ex ceeding four in number shall be cast or stamped on the pipe. All required markings shall be clear and legible and all cast marks shall be on or near the bell. All letters and numerals on pipe sizes 8 in. and larger shall be not less than ^ in. in height. Sec. 6-11--Weighing Pipe Each pipe shall be weighed before the application of any lining or coat ing other than the bituminous coating and the weight shall be shown on the outside or inside of the bell or spigot end. Sec. 6-12--Acceptance Testa The standard acceptance tests for the physical characteristics of the pipe shall be as follows: 6-12.1. Talbot strip tests. Talbot strip tests shall be used to determine the acceptability of 3-24 in. pipe for modulus of rupture and secant modu lus of elasticity. 6-12.1.1. Sampling. At least one sample shall be taken during each period 'of approximately 3 hr. The sample for the first period shall be taken during the first hour, or if cast ing is direct from the melting unit from the first ladle. Samples shall be CTD014654 4 AMERICAN NATIONAL STAN UAK1> taken so that each size of pipe continously cast for 2 hr or longer and each source of iron continuously used for 2 hr or longer shall be fairly repre sented. 6-12.1.2. Acceptance values. The modulus of rupture as determined by the Talbot strip test shall be 40 000 psi minimum. The secant modulus of elasticity value shall not exceed 300 times the actual value of the modulus of rupture. (For example: when the modulus of rupture is 40 000 psi, the secant modu lus of elasticity shall not exceed 12 000 000 psi.) 6-12.1.3. Test method. Talbot strips (Fig. 6.1) shall be machined Fig. 6.1. Position From Which Talbot atrip is Cut longitudinally from each pipe speci men selected for testing by this method. The Talbot strips may be cut from a part of the ring little stressed in the ring test--that is, near one of the elements marked a in the illustration of the ring test (Fig. 6.3). The strips in any case shall be in cross section as indicated in Fig. 6.1--that is, shall have for their width the thick ness of the pipe and for their depth 0.50 in. Their length shall be at least 10| in. The strips shall be tested as beams on supports 10 in. apart with loads applied perpendicularly to the machined faces at two points 3^ in. from the supports. The breaking load and the deflection shall be observed and recorded. The strip shall be accurately cali pered at the point of rupture and the modulus of rupture, R, shall be calcu lated by the usual beam formula, which for this case reduces to the expression lOW R = td* ) The secant modulus of elasticity, E,, in pounds per square inch, shall be computed by the formula ,, 21.32? In the above formulas, R is the modu lus of rupture (psi); E,, the secant modulus of elasticity (psi); W, the breaking load (lb); d, the depth (in.) of the strip (intended to be 0.50 in.); t, the width (in.) of the strip (pipe thickness); and y, the deflection (in.) of the strip at the center at breaking load. Deflection measurements shall be that of the specimen and shall not in clude any compression of the supports or loading blocks, or backlash or dis tortion of the testing machine. 6-12.2. Hardness tests. Hardness tests shall be made on the outside sur face of pipe. A sufficient number of pipe shall be tested to assure that the hardness does not exceed Rockwell B-95, or its equivalent. Pipe may be heat-treated to meet this requirement. For the purpose of foundry records, hardness tests shall be made on a specimen from each Talbot strip se lected for testing in Sec. 6-12.11. Rockwell B hardness determinations shall be made in accordance with ASTM E18-67 on the following sur faces at their approximate centers: (a) the outside pipe surface, (b) the inside pipe surface, and (c) either of the two cut surfaces. These three determina tions shall be made at three locations (1-2-3) along the length of the speci men, as shown in Fig. 6.2. The three determinations for each surface shall be averaged and no average value shall exceed Rockwell B-95. No single > CTD014655 KIPE CENTKIEUGALLY CAST IN METAL MOLDS 3 Fig. 6.2. Location of Rockwell Hardness Tests on Talbot Strip Specimen each strip and ring and the modulus of elasticity and hardness of each strip. 6-13.2. Ring test method. The maximum length of any ring shall not exceed 12 in.; for pipe 14 in. and larger, the minimum length shall be 10$ in.; for pipe 12 in. and smaller, the minimum length shall be one half the nominal diameter of the pipe. Each ring shall be tested by the threeedge bearing method as indicated in Fig. 6.3. The lower bearing for the determination on the Talbot strip shall exceed B-98. Sec. 6-13--Ring Tests and FullLength Bursting Tests 6-13.1. The manufacturer shall make bursting tests and ring tests in conjunction with strip tests so that he ( 0 can certify the design values of the modulus of rupture (40 000 psi) and the bursting tensile strength of the iron in the pipe (18 000 psi). These tests shall be made in accordance with dimensions and methods given in Sec. 6-13.2 and Sec. 6-13.3. At least one pipe sample for the ring and burst ing tests shall be selected from each of the following size groups from each calendar month's cast: Group 1 2 3 4 SUe in. ,6, 8 10 12 14, 16, 18 20, 24 When no pipe in a size group are manufactured during the calendar month, no tests on these sizes are required. Ring tests and bursting tests are not required on 3- and 4-in. pipe. At least three Talbot strips ^ \ shall be tested from each pipe selected * for bursting. Tests and records shall include the modulus of rupture of Fig. 6.3. Assembly for Ring Test ring shall consist of two strips with vertical sides having their interior top edges rounded to a radius of approxi mately $ in. The strips shall be of hard wood or metal. If of metal, a piece of fabric or leather approximately A in. thick shall be laid over them. They shall be straight and shall be securely fastened to a rigid block, with their interior vertical faces the following distances apart: Pipe Size *. 6-12 14-24 Bearing Strip Spaciag in. J 1 The upper bearing shall be a hard wood block, straight and true from end to end. The upper and lower bearings shall extend the full length of the ring. The ring shall be placed symmetrically between the two bearings, and the center of application of the load shall CTD014656 6 AMERICAN NATIONAL STANDARD be so placed that the vertical deforma tion at the two ends of the ring shall be approximately equal. If the ring is not uniform in thickness, it shall be so placed that the thick and thin por tions are near the ends of the hori zontal diameter. For purposes of Sec. 6-15, a record of the breaking load of each ring tested shall be made. The modulus of rup ture is computed from the formula W(d + t) R = 0.954 bfi in which R is the modulus of rupture (psi); W, the breaking load (lb); d, the average inside diameter (in.) of the ring; t, the average thickness (in.) of metal along the line of frac ture; and b, the length (in.) of the ring. 6-13.3. Burst test method. The bursting tensile strength shall be de termined by testing full-length pipe (less the amount cut off for ring and strip test specimens) to destruction by hydraulic pressure. Bells may be removed to facilitate testing. A suitable means for holding the end thrust shall be used which will not subject the pipe to endwise tension or compression, or other parasitic stresses. A calibrated pressure gage shall be used for determining the bursting pressure. The gage shall be connected to the interior of the test pipe by a separate connection from that which supplies water for the test. The unit tensile strength in bursting shall be obtained by the use of the formula in which S is the bursting tensile strength (psi) of the iron; P, the in ternal pressure (psi) at bursting; d, the average inside diameter (in.) of the pipe ; and t, the minimum average thickness (in.) of the pipe along the a principal line of break. * Measurements of thickness shall be j taken along the principal line of break at 1-ft intervals. The minimum average thickness along the principal line of break shall be obtained by averaging the measure ments at the thinnest section at a weight of two and at the adjacent sec tions on each side at a weight of one each; or, if the thinnest section is at the end of the break, by averaging the thinnest-section measurement at a weight of two and the measurements of the adjacent section and the next section at a weight of one each. Sec. 6-14--Chemical Analyses Analyses of the iron shall be made at sufficiently frequent intervals to determine compliance with the fol lowing limits: ^ Substance Maximum Limit B Per cent ~ Phosphorus Sulfur 0.90 0.12 Control of the other chemical con stituents shall be maintained to meet the physical property requirements of this standard. Samples for chemical TM analyses shall be representative and shall be obtained from either accept ance test specimens or specimens cast for this purpose. Sec. 6-15--Foundry Records The results of the following tests shall be recorded and retained for one year and shall be available to the pur chaser at the foundry. Written trans scripts of the results of these tests shall be furnished when specified on the pur chase order: 6-15.1. 6-15.2.

Sec. 6-18--Rejection of Pipe When any routine chemical analysis fails to meet the requirements of Sec. 6-14 or when any physical acceptance test fails to meet the requirements of Sec. 6-12.1, 6-12.2, or 6-17, the pipe cast in the same sampling period shall be rejected except as subject to the provision of Sec. 6-19. Sec. 6-17--Defective Specimens and Retests When any physical test specimen shows defective machining or lack of continuity of metal, it shall be dis carded and replaced by another speci men. When any sound test specimen fails to meet the specified require0 ments, the pipe from which it was taken shall be rejected and a retest may be made on two additional sound specimens from pipe cast in the same sampling period as the specimen which failed. Both of the additional speci- * Sec. 6-19--Determining Rejection The manufacturer may determine the amount of rejection by making similar additional tests of pipe of the same size as that rejected until the rejected lot is bracketed in order of manufacture by an acceptable test at each end of the interval in question. When pipe of one size is rejected from a sampling period, the acceptability of pipe of different sizes from that same period may be established by making the routine acceptance tests for these sizes.
