The material shall be of laminar con struction formed under pressure to a homo geneous structure and cured to meet the physical and chemical requirements of this specification. 6. Rubber Rings 6.1 The rubber rings used to seal the joints of the asbestos-cement pipe shall oonform to the requirements of the latest revision of Specification D 1869. 7. Chemical Requirements 7.1 When uncombined calcium hydroxide tests are requested, one sample shall be taken from each lot of pipe and tested in accordance with Sections 17 and 18 of Methods C 500. The sample to be tested may be taken from one of the specimens selected for the crushing test. The amount of uncombined calcium hy droxide shall not exceed 1.0 percent for Type II pipe. Note 4--There are no chemical requirements for Type I pipe. 8. Hydrostatic Strength 8.1 Each standard, random, or short length of pipe (see Section II) and each coupling sleeve, when manufactured from the same material as the pipe, shall be hydrostatically tested by the manufacturer prior to shipment and shall have sufficient strength to withstand the internal hydrostatic pressure prescribed in Table I, when tested in accordance with Sec tion 5 of Methods C 500. 8.2 From each lot of pipe which has passed the routine hydrostatic proof test, one length shall be selected by the inspector. A 12-in. (305-mm) or longer section of pipe cut from an unmachined portion of the selected length shall have the minimum hydrostatic strength designated in Table 2, when tested in accord ance with Section 5 of Methods C 500, except that the pressure need not be held for 5 s. 9. Flexural Strength 9.1 Each length of pipe in sizes 6 and 8 in. nominal diameter having lengths 10 ft (3.05 m) or longer shall have sufficient flexural strength to withstand without failure the total load prescribed in Table 3 when tested in ac cordance with Section 8 of Methods C 500. 10.1 From each lot. one length shall be se lected by the inspector. A I-ft (305-mm) sec tion of pipe cut from an unmachined portion of the selected length shall have the minimum crushing strength prescribed in Table 4 when tested in accordance with Section I I I I of Methods C 500. 11. Dimensions aad Permissible Variations II I Couplings and coupling areas of pipe shall be machined or otherwise finished to such dimensions as will provide tight joints when assembled with the proper accessories and put into service for which the pipe is in tended. 11.2 Pipe shall be manufactured with nom inal inside diameters of 6. 8. 10, 12, 14, 15, 16, 18, 20. 21, 24. 27. 30. 33. 36, 39. and 42 in. in the classifications defined in 3.1. except 6in. diameter pipe shall be of Classification 40 through 90 only. The average diameters of standard and random lengths may be less than the nominal inside diameter by not more than 5.0 percent, when measured approximately 3 in. (75 mm) from the end. 11.3 The standard length shall be 13 ft in. (3.96 m 25 mm). Alternative stand^B lengths shall be 10 ft 1 in. (3.05 m 75 mm) for 6-in. pipe and 16 ft I in. (4.88 m 25 mm) for 14-in. and larger pipe. At least 85 percent of the total footage of pipe of any one classification, type, and size, excluding short lengths, shall be furnished in standard lengths. The remaining 15 percent may be in random lengths of not less than 7 ft (2.13 m). Short lengths, when specifically ordered, shall not exceed 63/ ft (2.06 m). 12. Workmanship and Finish 12.1 Machined ends of the pipe that re ceive the coupling shall be free of dents and gouges that will affect the tightness of the joint. 12.2 Each pipe shall be free of bulges, dents, and tears in the inside surface that re sult in a variation in diameter of more than 2 CTD000494 7,, in. (S mm) from (hat obtained on adjacent unaffected portions of the surface. 3. Sampling 13.1 All samples shall be in a normal airdried condition when tests are initiated. 14. Inspection and Rejection 14.1 All material furnished under this spec ification shall conform to the requirements stated herein and shall be subjected to the fac tory inspection and tests prescribed in this specification. When requested by the pur chaser in his order (see Appendix XI). the manufacturer shall notify the purchaser of the time that the inspection and testing will take place so that the purchaser may arrange for witnessing such tests and inspections at his own expense. Instead of such inspection, when requested, the manufacturer shall be prepared to certify that his product conforms to the re quirements of this specification. 14.2 Pipe and couplings shall be inspected by the manufacturer, before shipment, for compliance with the standards for dimensions, and workmanship, and finish (See also Sec tions 7 to 10). 14.3 Failure of any specimen tested for crushing strength to withstand 75 percent of the load specified in Section 10 shall be cause for rejection of the lot from which the test specimen was taken. When any specimen tested for crushing strength withstands over 75 percent but under 100 percent of the load specified in Section 10. one specimen shall be cut from each of two additional pipes of the same lot. Failure of either of these additional specimens to meet the strength requirements of Section 10 shall be cause for rejection of the entire lot from which the original sample was taken. 14.4 If any pipe subjected to the hydro static strength lest described in 8.2 fails to withstand the pressure specified, two addi tional lengths of the same size and classifica tion shall be selected from the pipe manufac tured during the same shift and shall be sub jected to the specified pressure. The failure of one of these additional lengths to withstand the specified pressure shall be cause for rejec tion of the entire lot of that size and classifi cation manufactured during the same shift as the test lengths. 14.5 If the results of the uncombined cal cium hydroxide test shows that the sample failed to meet the specification requirements, two additional specimens shall be selected and sampled for test. The failure of one of these two additional samples to meet the specifica tion requirements of Section 7 shall be cause for rejection of the lot. 15. Marking and Shipping 15 1 Each standard and random length of pipe shall be marked by the manufacturer with the trade name, nominal size, classifica tion, and date of manufacture. The trade name shall include, but is not limited to. the manufacturer's name or trademark and the words "Transmission Pipe." Each coupling sleeve, if made of the same material as the pipe, shall be marked by the manufacturer with the nominal size, classification, and the letter "T" to indicate that it has been hydro statically tested. 15.2 Pipe and couplings shall be prepared for commercial shipment so as to ensure ac ceptance by common or other carriers.
