Materials and Manufacture 5.1 Asbestos-cement sewer pipe shall be composed of an intimate mixture of portland cement or portland blast-furnace slag cement and asbestos fiber with or without silica, or portland-pozzolan cement and asbestos fiber. The mixture shall be free of organic additives. The material shall be of laminar construction formed under pressure to a homogeneous structure and cured to meet the physical and chemical requirements of this specification. 6. Chemical Requirements 6.1 When tested in accordance with Sec tions 17 and 18 of ASTM Methods C 500, the amount of uncombined calcium hydroxide shall not exceed 1.0 percent for Ty pe 11 pipe. Notf 4--There are no chemical requirements for Type I pipe. 7. Dimensions and Permissible Variations 7.1 Couplings and coupling area of the pipe shall be machined or otherwise finished to such dimensions as will provide tight joints when assembled with proper accessories and put into service for which the pipe is intended. 7.2 The average diameter may be less than the nominal by not more than '/, in. (0.63 cm). 7.3 The standard lengths may be 5. 6.5, 10, or 13 ft (1,52. 1.98, 3.05 or 3.96 m) I in. (2.5 cm). At least 85 percent of the total foot age of any one class, type, and size, exclud ing short lengths, shall be furnished in stand ard lengths. The remaining 15 percent may be in random lengths of not less than 7 ft 12.13 m) when the standard length is 10 or 13 ft (3.05 or 3.96 m) and not less than 4 ft (I 22 m) when the standard length is 5 or 6.5 ft (I 52 or 1.98 m). 8. Workmanship 8 I The ends of the pipe that receive the coupling shall be free of dents and gouges that will affect the tightness of the joint. 8.2 Each pipe shall be free of bulges, dents, and tears in the inside surface that result in a variation of more than '/16 in. (0.48 cm) from the. adjacent unaffected portions of the surface. 8.3 Each length of pipe shall not vary in straightness by more than in./ft (5.2 mm/m) of length when the variation is meas ured in accordance with Section 13 of Methods C 500. 9. Sampling 9.1 For crushing tests, one full length of pipe shall be selected from each 500 lengths of 10 and 13-ft (3.05 and 3.96-m) lengths and each 1000 lengths of 5 and 6.5-ft (1.52 and 1.98-m) lengths of each size, class, and type of pipe covered by the order. One test specimen 12 in. (30.5 cm) long shall be cut from the un machined portion of the selected length of pipe. 9.2 When uncombined calcium hydroxide tests are requested (Section 6), one sample shall be taken from each lot of pipe. The sam ple to be tested may be taken from any one of the specimens selected for the crushing test. 9.3 All material tested under this specifi cation shall be in a normal air-dried condi tion. 10. Test Methods 10.1 Joint Tightness: 10.1.1 The tests outlined in this section are considered to be one-time qualification tests to establish the adequacy of the manufac turers joint design. Instead of requiring per formance of these tests, the purchaser may require the manufacturer to certify that pipes and couplings equivalent in material and de sign have passed the tests enumerated in this section. At his own expense, however, the purchaser, by designation with his order, may require that assembled pipes and couplings pass the following performance tests without leakage: 10.1.1.1 Straight Alignment-- Make hydro static pressure test on an assembly of two sec tions of pipe, properly connected with a cou pling in accordance with the joint design. An equivalent alternative may be a single pipr with a coupling on each end. Subject the assembly to an internal hydrostatic pressure of 10 psi (69 kPal for 10 min. Any visible water leakage shall be considered a failure of the tesl requirements. CTD014895 10.1.1.2 Maximum Deflected Position-- Upon completion of the test for pipes in straight alignment in accordance with 10.1.1.1, deflect the test sections 5 deg with one half of the deflection being between each pipe and the coupling and subject the test sections to an in ternal hydrostatic pressure of 10 psi (69 kPa) for 10 min. Any visible water leakage shall be considered a failure of the lest require ments. 10.1.2 Test one sample of each size unless some other arrangement is made with the purchaser by designation with his order. At the option of the purchaser, the sample of the pipes and couplings to be tested may be selected by him. 10.2 Flexural Strength: 10.2.1 Each length of pipe shall have suffi cient flexural strength to withstand, without failure, the total, load prescribed in Table I when tested in accordance with Section 8 of Methods C 500. 10.3 Crushing Strength: 10.3.1 Pipe--Conduct crushing tests before shipment. One-foot (0.3 m) lengths of pipe cut from unmachined portions of the pipe shall have the minimum crushing strength pre scribed in Table 2. when tested in accordance w ith Section 11.3 of Methods C 500. 10.3.2 Couplings--The couplings, when assembled on pipe, shall be capable of with standing simultaneously: 10.3.2.1 The minimum crushing strength m pounds-force per linear foot prescribed in Ta ble 2. when tested in accordance with 11.3 of Methods C 500. and 10.3.2.2 The hydrostatic pressure test de scribed in 10. I l l of this specification. 11. Inspection 11.1 All material furnished under this specification shall conform to the require ments stated herein and shall be subjected to the factory inspection and tests prescribed in this specification. When requested by the purchaser on his order, the manufacturer shall notify the purchaser of the time that 'he 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 requirements of this specification. 11.2 Pipe and coupling shall be inspected by the manufacturer, before shipment, for compliance with the standards for dimen sions. workmanship, and finish (see also Sec tion 9). 12. Rejection 12.1 Failure of the specimens tested for crushing strength to withstand 75 percent of the load specified in 10.3 shall be cause for rejection of the entire lot represented by the test specimens. When the specimen tested for crushing strength withstands over 75 per cent but under 100 percent of the load speci fied in 10.3. one specimen shall be cut from each of two additional pipes of the same size and class manufactured during the same shift. Failure of one of these additional specimens to meet the strength requirements of 10.3 shall be cause for rejection of the entire lot of that size and class manufactured during the same shift as the test specimen. 12.2 If the results of the uncombined cal cium hydroxide test show 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 6 shall be cause for rejection of the lot. 13. Marking and Shipping 13.1 Each standard and random length of pipe shall be marked by the manufacturer with the trade name, nominal size, class, and the date of manufacture. Each coupling sleeve shall be marked by the manufacturer with the nominal size and class for the pipe with which it shall be used. 13.2 Pipe and couplings shall be prepared for commercial shipment so as to ensure ac ceptance by common or other carriers. 14. Field Performance and Acceptance 14.1 All field-assembled joints for asbestoscemeni nonpressure small diameter sewer pipe shall meet the requirements set forth in 14,5 for infill ration/exfiltration. 14.2 Measurements shall be based on a segment or segments of sewer line of asbeslos- 3 # C 644 cement nonpressure small diameter sewer pipe installed separate!) or as a part of a sewer main system between two consecutive manholes or other similar increment of dis tance. rather than taken from a single joint 14..1 Before the sewer line is backfilled and tested, all pipe shall be inspected for proper bedding to assure uniform support of the pipe, and the absence of high points and irregularities which induce beam and shear loadings on the pipe. 14.4 Final acceptance testing shall be per- formed on the sewer line/s) after the final backfilling has been completed. 14.5 The infillration/exfiltration of the in stalled pipe shall not exceed 0.079 gal/in. of internal pipe diameter per 100 ft of pipelines/ h (0.586 litre/cm of internal pipe diameter per 100 m of pipelines per hour), where the maximum hydrostatic head at the center line of the pipe does not exceed 25 ft (7.63 m) (corresponds to 100 gal/in. of pipe diameter per mile per 24 h (92.6 litres/cm of pipe diam eter per 1000 m per 24 h).
