1.1 本规范涵盖了根据Schedule 40铁管尺寸（IPS）制造的配件和单挤出和共挤丙烯腈-丁二烯-苯乙烯（ABS）塑料排水管、废水管和通风管（DWV）。不符合第节规定的材料要求的塑料 5. 从单层和所有共挤层中排除。 1.2 符合本规范要求的管道配件规范见 附件A1 . 1.3 丙烯腈-丁二烯-苯乙烯塑料，不符合中给出的原始ABS塑料的定义 3.2.2 ，不包括在内，因为未确定除定义为原始塑料外的其他塑料的性能。ABS返工塑料，符合中给出的返工塑料要求 5.3 ，是可以接受的。 1.4 术语中定义的再加工塑料或再生塑料 D883 被排除在外。 1.5 储存、连接和安装建议见 附录X1 , 附录X2 ，以及 附录X3 分别。 1.6 本规范的文本引用了提供解释性材料的注释、脚注和附录。这些注释和脚注（不包括表格和图中的注释和脚注）不应被视为规范的要求。 1.7 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对国际单位制的数学转换，仅供参考，不被视为标准值。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

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.
