BNQ 3624-250/2015

1 PURPOSE AND SCOPE This standard specifies the characteristics and test methods relating to unplasticized poly(vinyl chloride) [PVC-U] pipe having a nominal diameter ranging from 100 mm to 1500 mm. This standard applies to socket-ended pipe with gasket seals made of elastomer, with or without a restraint system integrated to the pipe, and applies to pipe without socket. These pipes are intended for use in drinking-water systems and designed for pressurized water supply and distribution. These pipes may also be used in sewage backsiphonage systems. This standard also applies to poly(vinyl chloride) fittings, injection-moulded or made from pipe cuttings, and to poly(vinyl chloride) machined coupling fittings, used for assembling the pipes covered in this standard. NOTE —In this standard, the term "fabricated fitting" is used for fittings made from pipe cuttings. This standard does not address the assembly by butt fusion of pipe without socket on a worksite. This standard does not address molecularly oriented poly(vinyl chloride) [PVCO] pipe. This document was developed to serve as a reference document for conformity assessment activities of specific products. NOTE — Conformity assessment is defined as the systematic examination of the extent to which a (product, process, service) fulfils specified requirements.
