【国外标准】 Standard Specification for 12 to 60 in. [300 to 1500 mm] Dual and Triple Profile-Wall Polyethylene (PE) Pipe and Fittings for Sanitary Sewer Applications

This specification covers requirements and test methods for triple profile wall polyethylene pipe and fittings. 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. This specification covers pipe and fittings with an essentially smooth interior and exterior wall using an annular corrugated profile middle wall.1.1 This specification covers requirements and test methods for dual and triple profile wall polyethylene pipe and fittings. The nominal inside diameters covered are 12 in. to 60 in. [300 mm to 1500 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 an essentially smooth interior wall and either an annular corrugation (dual wall) or an essentially smooth and exterior wall using an annular corrugated profile middle wall (triple wall) (Fig. 1).FIG. 1 Typical Dual and Triple Wall Pipe Profile1.4 Units—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 caveat pertains only to the test method portion, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
