1.1 本规范涵盖了由热轧普通钢筋或棒材制成的垫（或薄板）形式的材料，用于混凝土加固。垫子是由两层钢筋或杆制成的，通过将交叉点焊接成直角来组装。 1.2 本规范适用于英寸磅单位（如A704）或国际单位制（如A704M]）的订单。 1.3 以英寸磅单位或国际单位制表示的数值应单独视为标准。在正文中，国际单位制显示在括号中。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。 1.4 本规范并非旨在解决与其使用相关的所有安全问题（如有）。本规范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。 1.5 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 material in mat (or sheet) form fabricated from hot-rolled, plain steel bars or rods to be used for the reinforcement of concrete. Mats are made from two layers of bars or rods that are assembled by welding the intersections at right angles to each other. 1.2 This specification is applicable for orders in either inch-pound units (as A704) or in SI units [as A704M]. 1.3 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. 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. 1.4 This specification 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 specification to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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.
