ABSTRACT This specification covers acrylonitrile-butadiene-styrene (ABS) schedule 40 plastic drain, waste, and vent pipe and fittings. ABS plastic which does not meet the material requirements is excluded. ABS plastic shall conform to the minimum content requirements of polymers or polymer blends and shall compose of acrylonitrile, butadiene, styrene or substituted styrene or both, and other monomeric or polymeric components. Pipe and fittings shall be homogenous and free of defects. Other requirements include dimensions, tolerances, stiffness, flattening, impact resistance, and bond strength. Sampling, conditioning, product marking, and quality shall conform to the requirements of this specification. SCOPE 1.1 This specification covers fittings and single and coextruded acrylonitrile-butadiene-styrene (ABS) plastic drain, waste, and vent pipe (DWV) made to Schedule 40 iron pipe sizes (IPS). Plastic which does not meet the material requirements specified in Section 5 is excluded from single layer and all coextruded layers. 1.2 Specification for fittings for use with pipe meeting the requirements of this specification are given in Annex A1. 1.3 Acrylonitrile-butadiene-styrene plastic, which does not meet the definition of virgin ABS plastic as given in 3.2.2, is excluded, as performance of plastic other than those defined as virgin was not determined. ABS rework plastic, which meets the requirements of rework plastic as given in 5.3, is acceptable. 1.4 Reprocessed plastic or recycled plastic as defined in Terminology D883 is excluded. 1.5 Recommendations for storage, joining, and installation are provided in Appendix X1, Appendix X2, and Appendix X3, respectively. 1.6 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification. 1.7 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. 1.8 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.
