1.1 本规范涵盖了用于天然气总管和直埋和插入应用设施的增强环氧树脂管和配件的材料、尺寸和公差、静水压爆裂强度、耐化学性和纵向拉伸性能的要求和试验方法。本规范所涵盖的管道和配件适用于天然气、石油燃料（丙烷-空气和丙烷-丁烷蒸汽混合物）、制造和混合气体的分配，其中要求具有抗气体渗透性、韧性、耐腐蚀性、老化性和水、气体和气体添加剂的劣化性。 并给出了标记方法。中讨论了设计注意事项 附录X1 。 1.2 以国际单位制表示的数值应视为标准。 1.3 以下安全隐患警告仅适用于本规范第8节测试方法部分: 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。 注1: 目前还没有与该标准等效的ISO。 1.4 建议的厂内质量控制程序见 附录X2 。 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 methods of test for materials, dimensions and tolerances, hydrostatic-burst strength, chemical resistance, and longitudinal tensile properties, for reinforced epoxy resin pipe and fittings for use in gas mains and services for direct burial and insertion applications. The pipe and fittings covered by this specification are intended for use in the distribution of natural gas, petroleum fuels (propane–air and propane–butane vapor mixtures), manufactured and mixed gases where resistance to gas permeation, toughness, resistance to corrosion, aging, and deterioration from water, gas, and gas additives are required. Methods of marking are also given. Design considerations are discussed in Appendix X1 . 1.2 The values in SI units are to be regarded as the standard. 1.3 The following safety hazards 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. Note 1: There is no known ISO equivalent to this standard. 1.4 A recommended inplant quality control program is given in Appendix X2 . 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.
