【国外标准】 Standard Specification for Acrylonitrile-Butadiene-Styrene (ABS) and Poly(Vinyl Chloride) (PVC) Composite Sewer Piping

This specification covers acrylonitrile-butadiene-styrene (ABS) and poly(vinyl chloride) (PVC) thermoplastic composite pipe, fittings, and a joining system for use in gravity flow, nonpressure sanitary sewer, and storm drain installations. ABS or PVC composite pipes shall consist of two concentric thermoplastic tubes integrally braced across the annulus and the resultant annular space shall be filled to provide continuous support between the inner and outer tubes. Referee and quality control tests shall be conducted in the standard laboratory atmosphere under the specified temperature and humidity conditions. The pipe shall be tested for performance requirements such as stiffness, deflection without rupture, acid conditioning, joint (solvent cement and elastomeric seal joints) tightness, and extrusion quality.1.1 This specification covers thermoplastic composite pipe, fittings and a joining system for use in gravity flow, nonpressure sanitary sewer, and storm drain installations. The pipe and fittings are made of ABS or PVC plastic material. Recommended installation practices are referenced in Appendix X1.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 The following safety hazards caveat pertains only to the test method portion, Section 10, 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.1.4 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.
