1.1 本规范涵盖混凝土钢筋用热轧棒材生产的碳钢丝和焊接钢筋。钢丝是冷加工、拉拔或轧制、普通（未变形、拉拔或镀锌）或变形的。焊接钢丝加固由普通钢丝或变形钢丝，或普通钢丝和变形钢丝的组合制成。中给出了常见的导线尺寸和尺寸 表1 , 表2 , 表3 和 表4 。实际导线尺寸不限于表中所示的尺寸。 注1: 用于混凝土钢筋的焊接钢丝在历史上被描述为各种术语:焊接钢丝网、WWF、织物和网格。钢筋行业采用了这个术语 焊接钢丝加固 （WWR）更能代表正在制造的产品的应用。因此，术语 焊接钢丝网 已替换为术语 焊接钢丝加固 在本规范和相关规范中。 1.2 以英寸磅单位或国际单位制表示的数值应单独视为标准。在文本中，SI单位显示在括号中（中除外 表2 和 表4 ). 每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。将两个系统的值合并可能导致不符合本规范。 1.3 本标准并不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。 1.4 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 carbon-steel wire and welded wire reinforcement produced from hot-rolled rod to be used for the reinforcement of concrete. The steel wire is cold-worked, drawn or rolled, plain (non-deformed, as-drawn or galvanized), or deformed. Welded wire reinforcement is made from plain or deformed wire, or a combination of plain and deformed wire. Common wire sizes and dimensions are given in Table 1 , Table 2 , Table 3 , and Table 4 . Actual wire sizes are not restricted to those shown in the tables. Note 1: Welded wire for concrete reinforcement has historically been described by various terms: welded wire fabric, WWF, fabric, and mesh. The wire reinforcement industry has adopted the term welded wire reinforcement (WWR) as being more representative of the applications of the products being manufactured. Therefore, the term welded wire fabric has been replaced with the term welded wire reinforcement in this specification and in related specifications. 1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text the SI units are shown in brackets (except in Table 2 and Table 4 ). The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with this specification. 1.3 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. 1.4 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.
