1.1 本规范涵盖了用于重力流系统的玻璃纤维管件，该系统用于输送生活污水、雨水和确定适用于该管件的工业废物。包括弯头、三通、支管、十字架、异径管和适配器。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）都是玻璃纤维管。 注1: 就本标准而言，聚合物不包括天然聚合物。 1.2 本规范仅涵盖尺寸、材料特性和工艺，而不是配件的结构设计。配件的结构设计应符合买方和供应商之间的约定，并需要考虑到预期的安装和使用条件。 1.3 本规范仅涵盖由切割的管段或由管段和接触模制（手工铺设）或机器制造的部件组合制成的配件。 1.4 以英寸-磅单位表示的值应被视为标准值。括号中给出的值仅供参考。 1.5 以下安全隐患警告仅适用于测试方法部分，第节 11 ，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。 注2: 目前还没有与该标准等效的ISO。 1.6 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 fiberglass pipe fittings intended for use in gravity flow systems for conveying sanitary sewage, storm water, and those industrial wastes for which the fittings are determined to be suitable. Elbows, tees, laterals, crosses, reducers, and adapters are included. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipes. Note 1: For the purposes of this standard, polymer does not include natural polymers. 1.2 This specification is intended to cover only dimensions, material properties, and workmanship rather than the structural design of the fittings. The structural design of the fittings shall be as agreed upon between purchaser and supplier, and needs to take into consideration the anticipated conditions of installation and service. 1.3 This specification covers only fittings fabricated from cut sections of pipe, or from a combination of pipe sections and contact molded (hand layup), or machine fabricated components. 1.4 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. 1.5 The following safety hazards caveat pertains only to the test method portion, Section 11 , 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. 1.6 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.
