1.1 本规范涵盖了排水、废物和通风应用的无压聚烯烃管道和配件的要求。 注1: 本规范不包括用于排放燃烧气体的管道和配件的要求。 1.2 管道按计划40和80 IPS尺寸、公制尺寸和DR IPS尺寸生产，用于两种聚烯烃；聚乙烯（PE）和聚丙烯（PP）。 1.3 本规范未涉及不同制造商制造的管道和管件的互换性。 1.4 管道和配件通过热熔方法连接（实践 D2657 对于PP对接和鞍座熔合，实践 F2620 用于PE对接、鞍座和插座的熔合和实践 F1290 对于聚烯烃电熔合），或使用管道和管件制造商推荐的机械或密封接头。 1.5 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.6 本规范的文本参考了提供解释材料的注释、脚注和附录。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本规范的要求。 1.7 以下安全危险警告仅适用于测试方法部分第节 8. ，本规范: 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。

1.1 This specification covers requirements for non-pressure polyolefin pipe and fittings for drainage, waste, and vent applications. Note 1: This specification does not include requirements for pipe and fittings intended to be used to vent combustion gases. 1.2 Pipe is produced in Schedule 40 and 80 IPS sizes, in metric sizes, and in DR IPS sizes for two polyolefins; polyethylene (PE) and polypropylene (PP). 1.3 The interchangeability of pipe and fittings made by different manufacturers is not addressed in this specification. 1.4 Pipe and fittings are joined by the heat fusion method (Practice D2657 for PP butt and saddle fusion, Practice F2620 for PE butt, saddle and socket fusion and Practice F1290 for polyolefin electrofusion) or by using mechanical or gasketed joints recommended by the pipe and fitting manufacturers. 1.5 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. 1.6 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 following safety hazards caveat pertains only to the test methods portion, Section 8 , of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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.
