7/2011 <br />15060 - 12 <br />so required; flanges which are too thin, not a right angles to the pipe centerline, or otherwise <br />distorted; together with all other flaws or defects which in the opinion of the Engineer, who’s <br />decision shall be final, adversely affect the assembly and/or function of the piping system as <br />intended. <br /> <br />2.02 PIPE AND FITTINGS: CAST IRON SOIL <br /> <br /> A. Cast iron soil pipe and fittings shall be cast gray iron, extra heavy, conforming to the <br />requirements of ASTM Standard A74 "Cast Iron Soil, Pipe and Fittings". <br /> <br /> B. Joints in soil pipe and fittings shall be made with neoprene rubber, compression type gaskets <br />conforming to ASTM Standard C564, "Rubber Gaskets for Cast Iron Soil Pipe and Fittings". <br /> <br /> C. Hubless EHCI with stainless steel and neoprene "Band-Aid" connections is only approved for <br />use in size 2-inches. All EHCI of larger diameter shall be hub pipe. <br /> <br />2.03 PIPE AND FITTINGS: POLY VINYL CHLORIDE (PVC) <br /> <br /> A. TYPE PSM SDR-35 PVC, AWWA C900 PVC AND C905 PVC SEWER PIPE AND FITTINGS <br /> <br />1. TYPE PSM SDR-35 PVC SEWER PIPE <br />Type PSM SDR-35 PVC Sewer Pipe for sewer mains and laterals shall conform to <br />ASTM Standard D 3034, "Specification for Type PSM Poly (Vinyl Chloride) (PVC) <br />Sewer Pipe and Fittings", except as modified herein. <br /> <br />a. Pipe shall be made of PVC thermoplastic having a cell classification of 12454-B, <br />12364-B, 12364-C or 13364-B as defined in ASTM Standard D 1784-90, "Specification <br />for Rigid Poly (Vinyl Chloride) (PVC) Compounds and Chlorinated Poly (Vinyl Chloride) <br />(CPVC) Compounds". <br /> <br />b. The PVC compounds used in the manufacture of the gravity sewer pipe shall be as <br />listed in the Plastic Pipe Institute (PPI) Technical Report TR-4. <br /> <br />c. The PVC pipe shall be push-on type, with bells, spigots and elastomeric gaskets, in <br />accordance with ASTM Standard D 3034, and in accordance with ASTM Standard D <br />3212, "Specification for Joints for Drain and Sewer Plastic Pipes Using Flexible Elas- <br />tomeric Seals", except as otherwise modified herein. The gaskets shall be the sole <br />element depended upon to make the joint flexible and watertight. Joints using solvent <br />cement will not be permitted. The pipe bells shall have an annular recess or race to <br />seat and retain the gasket, and the gaskets may be either prepositioned by the manu- <br />facturer, or shipped separately in suitable protective containers. Pipe spigots shall be <br />beveled. Pipe bells shall be extruded integral with the pipe barrel with a thickness <br />equal to or greater than that of the barrel. <br /> <br />d. The gaskets shall be fabricated from a high-grade elastomer compound in accordance <br />with ASTM Standard F 477, "Specification for Elastomeric Seals (Gaskets) for Joining <br />Plastic Pipe", except as otherwise modified herein. The basic polymer for the gaskets <br />shall be synthetic rubber. Natural rubber gaskets, or gaskets with both natural and <br />synthetic rubbers will not be permitted. Gaskets shall be continuous, elastomeric, ru b- <br />ber ring type. <br />
