1.1 本规范涵盖铝合金轧制平面踏脚板，轧制完成面，一侧有凸起图案，合金、温度和厚度如所示 表1 和 表2 [ 表3 ]. 1.2 合金和回火名称应符合ANSI H35.1/H35.1M的规定。等效的统一编号系统合金名称应符合规程 E527 . 1.3 有关本规范中包含新铝和铝合金的验收标准，请参见 附件A2 . 1.4 以英寸磅或国际单位制表示的数值应单独视为标准。国际单位制显示在括号中或单独的表格中。每个系统中规定的数值并不完全相等；因此，每个系统都必须独立使用。 将两个系统的值结合起来会导致不符合规范。 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 aluminum-alloy rolled flat tread plate, mill-finish, with a raised pattern on one side, in the alloy, tempers, and thicknesses shown in Table 1 and Table 2 [ Table 3 ]. 1.2 Alloy and temper designation are in accordance with ANSI H35.1/H35.1M. The equivalent Unified Numbering System alloy designation shall be in accordance with Practice E527 . 1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2 . 1.4 The values stated in either inch-pound or SI units are to be regarded separately as standard. The SI units are shown either in brackets or in separate tables. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems will result in nonconformance with the specification. 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.
