1.1 本规范涵盖了材料、尺寸、工艺、抗压扁性、抗冲击性、管道刚度、挤压质量、连接系统和18至60英寸大直径标记形式的要求和测试方法。带整体钟形弹性密封接头或溶剂胶结套筒的聚氯乙烯（PVC）污水管和管件。 1.2 本规范的要求旨在提供适用于污水和地表水非压力排水的管道和配件。 按照本规范生产的管道和管件应按照惯例安装 D2321 . 注1: 由于温度超过140℃，因此只能在获得管理法规机构的特别批准后安装工业废物处理管线 华氏度（60 °C），可能会遇到排水沟和下水道中不常见的化学品。 1.3 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。 1.4 以下预防性警告仅适用于试验方法部分第节 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。 1.5 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《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 and test methods for materials, dimensions, workmanship, flattening resistance, impact resistance, pipe stiffness, extrusion quality, joining system, and a form of marking for large diameters, 18 to 60 in. poly(vinyl chloride) (PVC) sewer pipe and fittings with integral bell elastomeric seal joints or solvent cemented sockets. 1.2 The requirements of this specification are intended to provide pipe and fittings suitable for nonpressure drainage of sewage and surface water. Pipe and fittings produced to this specification should be installed in accordance with Practice D2321 . Note 1: Industrial waste disposal lines should be installed only with the specific approval of the governing code authority since temperatures in excess of 140 °F (60 °C) and chemicals not commonly found in drains and sewers may be encountered. 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 method 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. 1.5 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.
