1. Scope 1.1 This Standard applies to poly (vinyl chloride) drain, waste, and vent (PVC-DWV) and chlorinated poly (vinyl chloride) drain, waste, and vent (PVC-DWV) pipe, pipe fittings, and accessories such as factory-assembled expansion joints, closet flanges, and backwater valves. 1.2 This Standard includes requirements for materials, quality of work, dimensions and tolerances, impact strength, chemical resistance, water resistance, dimensional stability, hydrostatic strength, solvent cement, and marking, as well as performance requirements for expansion joints, closet flanges, and backwater valves. Notes: (1) Recommended installation practices for PVC-DWV pipe are given in Appendix A. Use of these recommended practices will help to ensure proper installation and optimum service life. (2) The maximum pressure used to test DWV installations should be 100 kPa (see Clause A5.2). 1.3 The valves in SI (metric) units are the standard. Valves in parentheses are for information only.
