1.1 本规范涵盖了合成纤维增强混凝土管（Syn FRCP），用于输送污水、工业废物和雨水，以及建造涵洞。 注1: 经验表明，该产品的成功性能取决于正确选择管道强度、垫层和回填类型、注意安装是否符合施工规范以及是否在施工现场进行充分检查。本规范不包括垫层、回填、现场荷载条件与管道强度指标之间的关系或异常环境条件下的耐久性要求。这些要求应包含在项目规范中。 注2: 本产品为刚性管道，不依赖于土壤额外支撑的挠度（管道刚度）。 注3: 本标准要求对Syn进行长期测试- FRCP符合第节 9 为了评估纤维混凝土基体的长期材料强度，这超出了钢筋混凝土管的典型要求。 1.2 单位- 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。 1.3 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 synthetic fiber reinforced concrete pipe (Syn-FRCP), intended to be used for the conveyance of sewage, industrial wastes, and storm water and for the construction of culverts. Note 1: Experience has shown that the successful performance of this product depends upon the proper selection of the pipe strength, the type of bedding and backfill, the care that the installation conforms to the construction specifications, and provision for adequate inspection at the construction site. This specification does not include requirements for bedding, backfill, the relationship between field load conditions and the strength designation of pipe, or durability under unusual environmental conditions. These requirements should be included in the project specification. Note 2: This product is a rigid pipe and it does not depend upon deflection (pipe stiffness) for additional support from the soil. Note 3: This standard requires long-term testing of Syn-FRCP in accordance with Section 9 that goes above and beyond what is typically required for steel reinforced concrete pipe, in order to evaluate the long-term material strength of the fiber-concrete matrix. 1.2 Units— 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. 1.3 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.
