1.1 本规范涵盖按照标准内部尺寸比（SIDR）和水额定压力制造的聚乙烯（PE）管（见附录）。包括PE化合物的要求以及工艺、尺寸、高温持续压力、爆裂压力和标记的要求和试验方法。 注1: 有关管道适用于饮用水最终用途的更多信息，请参阅AWWA C901规范和PPI技术注释49（TN-49）。 可从NSF International获得抗氧化等级（CC#等级）信息。 1.2 以英寸-磅单位表示的值应视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准值。 1.3 本规范的正文引用了提供说明材料的注释、脚注和附录。这些注释和脚注不应视为本规范的要求。 表和图中的注释和脚注以及补充要求是本规范的要求。 1.4 以下安全隐患警告仅适用于测试方法部分，第节 7. ，本规范: 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers polyethylene (PE) pipe made to standard inside dimension ratios (SIDR) and pressure rated for water (see appendix). Included are requirements for PE compounds and requirements and test methods for workmanship, dimensions, elevated temperature sustained pressure, burst pressure, and marking. Note 1: Refer to specification AWWA C901and PPI Technical Note 49 (TN-49) for further information on pipe suitability for potable water end use applications. Oxidative Resistance Classification (CC# rating) information is available from NSF International. 1.2 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. 1.3 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes shall not be considered as requirements of the specification. Notes and footnotes in tables and figures, and Supplementary Requirements are requirements of the specification. 1.4 The following safety hazards caveat pertains only to the test methods portion, Section 7 , 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. 1.5 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.
