【国外标准】 Standard Specification for Poly(Vinyl Chloride) (PVC) Gasketed Sewer Fittings

This specification covers the material, dimensional, and mechanical requirements, and associated test methods for fabricated or molded poly(vinyl chloride) (PVC) gasketed sewer fittings manufactured from pipe, or from a combination of pipe and injection molded parts, or from injection molded parts that are suitable for non-pressure drainage of sewage and surface water, as well as applications involving subsurface drainage. The fittings shall adhere to specified values for outside diameter, wall thickness, socket length, and spigot length. When evaluated according to the test procedures provided herein, the fittings shall meet specified requirements for impact strength, pipe stop load support, internal stress, and branch bending. The products shall also undergo referee testing and quality control tests.1.1 This specification covers requirements and test methods for fabricated or molded poly(vinyl chloride) (PVC) gasketed sewer fittings to be used with piping manufactured to Specifications D3034, F679, F891 or F1760. Fabricated fittings may be manufactured from pipe, or from a combination of pipe and injection molded parts, or from injection molded parts. Gasketed sewer fitting configurations may include one or more spigot outlets.1.2 The requirements of this specification are to provide fabricated or molded PVC gasketed fittings suitable for non-pressure drainage of sewage and surface water, as well as applications involving subsurface drainage.NOTE 1: Industrial waste lines should be installed only with the specific approval of the governing code authority when using chemicals not commonly found in drains and sewers or temperatures in excess of 140 °F (60 °C), or both.1.3 Fittings produced to this specification are intended to be installed with pipe, in accordance with Practice D2321.1.4 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.1.5 The following precautionary caveat pertains to the test method portion only, 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.1.6 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.
