1.1 本规范涵盖玄武岩和玻璃纤维增强聚合物（分别为BFRP和GFRP）钢筋，以直（纵向）切割长度提供，具有实心圆形横截面，并具有用于内部混凝土钢筋应用的表面增强。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 小节 1.6 定义了超出本规范范围的FRP筋的类型。 1.3 根据本标准生产的棒材采用试验方法进行合格评定，且必须满足 表1 .棒材生产批次的质量控制和认证是使用测试方法完成的，必须符合 表2 . 1.4 FRP筋的标准尺寸和尺寸及其编号如所示 表3 . 1.5 本规范的文本引用了提供解释性材料的注释和脚注。这些注释和脚注（不包括表中的注释和脚注）不应被视为规范的要求。 1.6 本规范不包括以下FRP筋材料: 1.6.1 由一种以上承重纤维类型或不同等级纤维（即混合FRP）制成的棒材。 1.6.2 由玻璃或玄武岩以外的纤维制成的棒材。 1.6.3 没有外表面增强的钢筋（即普通或光滑的钢筋或销钉）。 1.6.4 具有非实心圆形横截面几何形状的钢筋。 1.6.5 预制格栅和格栅由玻璃钢材料制成。 1.6.6 弯曲钢筋（即不是由直的、连续的长度制成的钢筋）。 注1: 弯钢筋可能包括箍筋和箍筋。参考规范 D7957/D7957米 用于GFRP弯钢筋规范。 1.7 本规范适用于SI（如规范D8505M）或US单位（如规范D7505）。 1.8 以国际单位制或美国单位表示的数值应视为标准。在文本中，美国单位显示在括号中。每个系统中规定的数值并不完全相等；因此，每个系统应独立于其他系统使用。将两个系统的值组合在一起可能会导致不符合规范。 1.9 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。 1.10 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 basalt and glass fiber reinforced polymer (BFRP and GFRP, respectively) bars, provided in straight (longitudinal) cut lengths, of solid round cross-section, and having a surface enhancement for internal concrete reinforcement applications. Bars covered by this specification shall meet the requirements for geometric, material, mechanical, and physical properties as described herein. 1.2 Subsection 1.6 defines the type of FRP bars that are out of the scope of this specification. 1.3 Bars produced according to this standard are qualified using the test methods and must meet the requirements given in 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 . 1.4 The standard sizes and dimensions of FRP bars and their number designations are given in Table 3 . 1.5 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. 1.6 The following FRP bar materials are not covered by this specification: 1.6.1 Bars made of more than one load-bearing fiber types or different grade fibers (that is, hybrid FRP). 1.6.2 Bars made from fibers other than glass or basalt. 1.6.3 Bars having no external surface enhancement (that is, plain or smooth bars, or dowels). 1.6.4 Bars with geometries other than solid, round cross sections. 1.6.5 Pre-manufactured grids and gratings made with FRP materials. 1.6.6 Bent bars (that is, bars that are not made of straight, continuous lengths). Note 1: Bent bars may include stirrups and hoops. Refer Specification D7957/D7957M for GFRP bent bar specifications. 1.7 This specification is applicable for either SI (as Specification D8505M) or US units (as Specification D8505). 1.8 The values stated in either SI units or US units are to be regarded as standard. Within the text, the US units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 1.9 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. 1.10 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.
