1.1 本规范涵盖了材料、尺寸和公差、挠曲载荷、抗压性、抗压扁性、抗冲击性和溶剂型水泥的要求和试验方法。还包括一种标记形式。不符合第节规定的材料要求的塑料 5. 被排除在外。 注1: 本规范以前以“3英寸薄壁聚氯乙烯（PVC）塑料排水管、废水管和通风管及配件”的标题发布。 1.1.1 实践中给出了制作溶剂型水泥接缝的技术 D2855 . 1.2 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。 1.3 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。 1.4 以下预防性警告仅适用于测试方法部分，第节 7. ，根据本规范: 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。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 requirements and test methods for materials, dimensions and tolerances, deflection load, crush resistance, flattening resistance, impact resistance, and solvent cement. A form of marking is also included. Plastic which does not meet the material requirements specified in Section 5 is excluded. Note 1: This specification was formerly issued under the title, 3-in. Thin Wall Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings. 1.1.1 Techniques for making solvent-cement joints are given in Practice D2855 . 1.2 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. 1.3 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. 1.4 The following precautionary 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.
