A maximum of 10 percent of the total footage of any one size for any one order may be furnished by the manufacturer in pipe lengths less than standard 10-foot lengths but not less than 7 feet. These short lengths shall be termed random lengths. 2.22 Half Lengths: Half lengths ordered for use in making rigid connections to fittings and structures shall not exceed 5 feet. A maximum of 10 percent of the footage of half lengths for any one size for any one order may be furnished in pipe lengths less than 5 feet but not less than 4 feet. These short lengths shall be termed random half lengths. 2.3 Couplings: One rubber ring type coupling shall be furnished with each standard, half, random, and random half length of pipe. It shall consist of an asbestos-cement sleeve with a rubber center ring plus two rubber sealing rings, suitable for the particular size of pipe for which it will be used. Sufficient Lubricant shall be furnished to effect assembly of joints. 2.4 Materials: 2.41 Pipe and Sleeve of Coupling: Asbestos-Cement Building Sewer Pipe and the sleeve of the Coupling shall be composed of an intimate mixture of cement and asbestos fiber with or without the addition of curing agents and shall be free from organic substances. 2.42 Rubber Rings: The rings shall consist of a molded and vulcanized rubber compound. 2.43 Lubricant: The lubricant shall be a modified soap of vegetable origin. SECTION 3 - DETAILED REQUIREMENTS: 3.1 Pipe: 3.11 Dimensions and Tolerances: Asbestos-Cement Building Sewer Pipe shall conform to the dimen- sions and tolerances given in Table I, following.

When requested on his order, the purchaser may witness inspection and test procedures at his own expense. In lieu of this, he may request on his order that the manufacturer submit a certificate certifying the produce meets the requirements of this specification. Flexural Test: Each standard length of pipe in sizes 4, 5 and 6 inches shall be flexurally tested by the manufacturer before shipment for compliance with the flexural requirements specified in Table 11, Section 3.12. The length of standard pipe shall be supported on a standard flexure testing machine with a clear span of 9 feet between supports. The total load shall be divided equally and applied at the third points of the 9-foot span. Crushing Test: Crushing tests shall be conducted, before shipment, by the manufacturer when requested by the purchaser on his order. When so requested, the tests shall be conducted at the purchaser’s expense and in the following manner. SECTION 4 - INSPECTION, TESTS AND REJECTIONS (continued) : 4.1 Pipe: (continued) From each 300 lengths of each size of pipe or iraction thereof, one specimen length of pipe shall be selected. From the specimen pipe there shall be cut one unmachined section of pipe six-inches long. The sample shall be tested in crushing by the A.S.T.M. 3-Edge Bearing Method and shall not fail until the total applied load exceeds half the tabular value given in Table 111 for the size of pipe being tested. Failure of this specimen to meet 75 percent of the crushing strength requirements specified in Section 3.13 shall be cause for rejection of the entire production of that size manufactured on the same day as the test specimen. If the specimen fails to meet the crushing strength requirements as specified in Section 3.13, but meets not less than 75 percent or more of these requirements, one specimen each of five ad- ditional pipe of the same size manufactured on the same day as that of the specimen which failed, shall be tested., Failure of two of these additional specimens to meet the crushing strength requirements shall be cause for rejection of the entire production of that size manufactured on the same day as the test specimen. In addition, failure of any one specimen to develop 75 percent of the re- quired crushing strength shall be cause for rejection of the entire production of that size man- ufactured on the same day as the test specimen. L 4.14 Alkalinity Test: The alkalinity test shall be conducted by the manufacturer when requested by the purchaser on his order. When so requested, the test shall be conducted at the purchaser’s expense and in the following manner. Representative samples of pipe or sleeves shall be selected and ground so that they completely pass a 20-mesh sieve. They shall be dried at 105 C for two hours in the absence of CO, and cooled in a desiccator. A one-gram sample shall then be placed in a 4-02. oil sample bottle with 100 cc of cold distilled water. The bottle shall then be shaken vigorously for five seconds at hourly intervals during an 8-hour working day and allowed to stand the remainder of 24 hours. The residue shall then be filtered and washed with 3 portions, 25 cc each, of cold distilled water. The filtrate and washings shall then be combined and titrated with N/10 HC1, using methyl orange indicator. A titration “blank shall be prepared for use as a control in measuring the end point. The net alkalinity shall be calculated as milligrams of KOH per gram of sample, and shall not be more than that specified in Section 3.3. 4.2 Couplings: 4.21 Inspection: Each rubber ring type coupling shall be inspected by the manufacturer, before ship- ment, for compliance with the dimension and tolerances specified in Section 3.21. SECTION 5 - MARKING: 5.1 Pipe: Each standard length, random length, half length and randoin half length of pipe shall be indelibly marked by the manufacturer with Vi’’ wide red bands approximately at 12” on centers, date of manufacture, nominal size, and the words “Building Sewer.” 5.2 Rubber ring type couplings: Each coupling shall be marked by the manufacturer with the initials “B.S.” and the nominal size of the pipe with which it shall be used. SECTION 6 - PREPARATION FOR SHIPMENT: Asbestos-Cement Building Sewer Pipe and rubber ring type couplings shall be prepared for standard commercial shipment so as to assure acceptance by common or other carrier.
