1.1 本规范涵盖6英寸聚合物混凝土管。（150 mm）至144 in。(3 660 mm），用于输送生活污水、雨水和工业废物的重力流系统。 1.2 虽然本规范主要适用于直埋和顶管安装的管道，但在适用于其他安装的范围内，如滑动和修复现有管道。 注1: 与增强热固性树脂管不同，聚合物混凝土管的设计和安装采用刚性管设计理论和实践。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.4 以下安全危险警告仅适用于测试方法部分第节 8. ，符合本规范。 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。 注2: 没有已知的ISO等效于本标准。 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 polymer concrete pipe, 6 in. (150 mm) through 144 in. (3 660 mm), intended for use in gravity-flow systems for conveying sanitary sewage, storm water, and industrial wastes. 1.2 Although this specification is suited primarily for pipe to be installed by direct burial and pipe jacking, it may be used to the extent applicable for other installations such as sliplining and rehabilitation of existing pipelines. Note 1: Unlike reinforced thermosetting resin pipes, polymer concrete pipe is designed and installed using rigid pipe design theory and practices. 1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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. Note 2: There is no known ISO equivalent to this standard. 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.
