1.1 本规范涵盖由低碳冷还原钢制成的单块还原黑板，按卷和切割尺寸提供，用于制造容器、封口、标志、玩具和其他产品，以及电镀应用。 1.2 它可以是干燥的或经过润滑的，也可以进行表面处理或不进行表面处理。此产品通常带有修边。 1.3 本规范适用于以英寸磅为单位（如A625）的订单，其供应厚度为135磅基本重量（0.0149英寸）及以下，或以国际单位制（如A625M）为单位，其供应的厚度为0.378毫米及以下。 1.4 以英寸磅或国际单位制表示的数值应视为标准。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可能会导致不符合本规范。 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 single-reduced black plate produced from low carbon, cold-reduced steel, furnished in coils and cut sizes, for use in the manufacture of containers, closures, signs, toys and other products, as well as for plating applications. 1.2 It may be supplied dry or oiled and with or without surface treatment. This product is normally supplied with a trimmed edge. 1.3 This specification is applicable to orders in either inch-pound units (as A625), which is supplied in thicknesses from 135-lb base weight (0.0149 in.) and lighter, or SI units (as A625M), which is supplied in thicknesses from 0.378 mm and lighter. 1.4 The values stated in either inch-pound or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. 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 may result in nonconformance with this 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.
