1. Scope 1.1 This Standard applies to acrylonitrile-butadiene-styrene drain, waste, and vent (ABS-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 ABS-DWV pipe are given in Appendix A. Use of these recommended practices will help 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 value in SI (metric) units are the standard. Values in parentheses are for information only.
