ASTM F2764-10

Standard Specification for 30 to 60 in. [750 to 1500 mm] Polypropylene (PP) Triple Wall Pipe and Fittings for Non-Pressure Sanitary Sewer Applications

SCOPE
1.1 This specification covers requirements and test methods for triple wall polypropylene pipe and fittings. The nominal inside diameters covered are 30 to 60 in. [750 to 1600 mm].
1.2 The requirements of this specification are intended to provide pipe and fittings suitable for underground use for non-pressure sanitary sewer systems. Pipe and fittings produced in accordance with this specification shall be installed in compliance with Practice D2321.
1.3 This specification covers pipe and fittings with a interior wall, a exterior wall and an annular corrugated profile middle wall (Fig. 1).
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.5 The following precautionary statement applies only to Section 7 of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
