1.1 本规范涵盖了切割长度和弯曲形状的玻璃纤维增强聚合物（GFRP）钢筋，并具有混凝土钢筋的外表面增强。本规范涵盖的钢筋应满足本文所述的几何、材料、机械和物理性能要求。 1.2 根据本标准生产的钢筋通过测试方法合格，并且必须满足 表1 . 生产批次的质量控制和认证使用测试方法完成，并且必须满足中给出的要求 表2 . 1.3 本规范的正文引用了提供解释材料的注释和脚注。这些注释和脚注（不包括表中的注释和脚注）不应视为本规范的要求。 1.4 本规范不包括以下FRP材料: 1.4.1 由多种承重纤维类型（即混合FRP）制成的钢筋。 1.4.2 没有外表面增强的钢筋（即，平直或光滑的钢筋或定位销）。 1.4.3 几何形状不同于实心圆形截面的钢筋。 1.4.4 由FRP材料制成的预制格栅和格栅。 1.5 本规范适用于SI（规范D7957M）或英寸-磅单位（规范D7957）。 1.6 单位- 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.7 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。 1.8 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 glass fiber reinforced polymer (GFRP) bars, provided in cut lengths and bent shapes and having an external surface enhancement for concrete reinforcement. Bars covered by this specification shall meet the requirements for geometric, material, mechanical, and physical properties described herein. 1.2 Bars produced according to this standard are qualified using the test methods and must meet the requirements given by Table 1 . Quality control and certification of production lots of bars are completed using the test methods and must meet the requirements given in Table 2 . 1.3 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables) shall not be considered as requirements of the specification. 1.4 The following FRP materials are not covered by this specification: 1.4.1 Bars made of more than one load-bearing fiber type (that is, hybrid FRP). 1.4.2 Bars having no external surface enhancement (that is, plain or smooth bars, or dowels). 1.4.3 Bars with geometries other than solid, round cross sections. 1.4.4 Pre-manufactured grids and gratings made with FRP materials. 1.5 This specification is applicable for either SI (as Specification D7957M) or inch-pound units (as Specification D7957). 1.6 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.7 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. 1.8 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.
