Standard Specification for Tin Mill Products, Black Plate, Double Reduced 二次还原镀锡板轧制产品标准规范
发布日期: 2024-03-01
1.1 本规范涵盖了主要用于集装箱制造的由低碳冷还原钢制成的双还原黑板,按卷和切割尺寸提供。产品可以被指定为“已轧制”,无需去除轧制溶液,也无需额外的表面或润滑处理。也可以指定在去除轧制溶液的情况下进行“清洁”,无论是否进行表面处理和加油。此产品通常带有修边。 1.2 本规范适用于以英寸磅单位(如A650)提供的订单,其厚度为0.0050英寸至0.0113英寸,或以SI单位【如A650M】提供的厚度为0.127毫米至0.287毫米。 1.3 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。 1.4 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 double-reduced black plate, produced from low-carbon cold-reduced steel, furnished in coils and cut sizes, for use predominantly in the manufacture of containers. The product may be specified “as rolled,” without the removal of the rolling solution, and with no additional surface or oiling treatment. It may also be specified “cleaned” with the rolling solution removed, with or without surface treatment and oiling. This product is normally supplied with trimmed edges. 1.2 This specification is applicable to orders in either inch-pound units (as A650) which is supplied in thicknesses 0.0050 in. to 0.0113 in. or SI units [as A650M] which is supplied in thicknesses from 0.127 to 0.287 mm. 1.3 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. 1.4 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.
