【国外标准】 Standard Specification for Poly (Vinyl Chloride)(PVC) Closed Profile Gravity Pipe and Fittings Based on Controlled Inside Diameter

This specification covers the requirements for poly(vinyl chloride) closed profile gravity sewer pipe and fittings with integral bell and elastomeric seal joints or plain end pipe with couplings based on a controlled inside diameter intended for non-pressure drainage of sewage and surface water. The integral bell gasketed joint, coupling, or fitting joints shall be designed in such a way that when assembled, the gasket (which is attached to either the bell or the spigot) will be compressed radially on the pipe spigot or in the bell to form a water-tight seal. The pipe and fittings shall comply with the following requirements: inside diameter, wall thickness, bell wall thickness, stiffness, flattening, impact strength, low head application of gasket, joint tightness, and resistance of exposed channels to infiltration, exfiltration, and sewer or drainage environments. Acetone immersion and air tests shall be performed to determine the degree of fusion of extruded plastic pipe and the air tightness or the minimum dwell period of the specimen, respectively.1.1 This specification covers requirements for poly(vinyl chloride) (PVC) closed profile sewer pipe and fittings with integral bell and elastomeric seal joints or plain end pipe with couplings in sizes (18 to 60 in.) based on a controlled inside diameter.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 hazard caveat pertains only to the test methods portion, Section 8, 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.NOTE 1: Pipe and fittings produced to this specification should be installed in accordance with Practice D2321.1.4 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.
