1.1 本规范涵盖8英寸（200 mm）至156英寸（4000 mm）的机制玻璃纤维管，用于内部表压小于等于450 psi（3103 kPa）的输水系统。玻璃纤维增强热固性树脂管（RTRP）和玻璃纤维增强聚合物砂浆管（RPMP）均为玻璃纤维管。该标准主要适用于埋地应用中安装的管道，但也可在适用于其他安装的范围内使用，如但不限于现有管道的顶管、隧道衬砌和滑动衬砌修复。 注1: 就本标准而言，聚合物不包括天然聚合物。 1.2 以英寸磅为单位的数值应视为标准。括号中给出的值仅供参考。 注2: 目前还没有与该标准等效的ISO。 1.3 以下安全隐患警告仅适用于第节测试方法部分 8. ，本规范的: 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。 1.4 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 machine-made fiberglass pipe, 8 in. (200 mm) through 156 in. (4000 mm), intended for use in water conveyance systems which operate at internal gage pressures of 450 psi (3103 kPa) or less. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipes. The standard is suited primarily for pipes to be installed in buried applications, although it is acceptable to be used to the extent applicable for other installations such as, but not limited to, jacking, tunnel lining and slip-lining rehabilitation of existing pipelines. Note 1: For the purposes of this standard, polymer does not include natural polymers. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. Note 2: There is no known ISO equivalent to this standard. 1.3 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. 1.4 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.
