1.1 本规范 2 涵盖一组通用要求，除非采购订单或个别规范中另有规定，否则应适用于ASTM发布的以下每一规范下的轧制钢板、薄板和带钢:规范 A240/A240M , A263 , A264 , A265 , A666 , A693 , A793 ，和 A895 . 1.2 如果产品质量标准的要求与本规范的要求发生冲突，应以产品质量标准为准。如果产品规范的要求或本规范的要求与采购订单中更严格的要求发生冲突，则以采购订单为准。如果采购订单要求以任何方式违反产品规范或本规范的要求，则不应优先；例如，通过放弃测试要求或通过使测试要求不那么严格。 1.3 以SI单位或英寸-磅单位表示的值应单独视为标准值。SI单位显示在括号中，但以下情况除外 A480M 是指定的， Annex A3 应适用于尺寸公差，而不是中括号内的SI值 Annex A2 每个系统中陈述的值不一定是完全等同的；因此，为确保符合标准，每个系统应独立使用，两个系统的数值不得合并使用。 1.4 本规范和适用材料规范均以英寸-磅和SI单位表示。但是，除非订单规定了适用的“M”规格名称[SI单位]，否则材料应以英寸为单位提供-磅单位。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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 2 covers a group of general requirements that, unless otherwise specified in the purchase order or in an individual specification, shall apply to rolled steel plate, sheet, and strip, under each of the following specifications issued by ASTM: Specifications A240/A240M , A263 , A264 , A265 , A666 , A693 , A793 , and A895 . 1.2 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; for example, by waiving a test requirement or by making a test requirement less stringent. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The SI units are shown in brackets, except that when A480M is specified, Annex A3 shall apply for the dimensional tolerances and not the bracketed SI values in Annex A2 . The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4 This specification and the applicable material specifications are expressed in both inch-pound and SI units. However, unless the order specifies the applicable “M” specification designation [SI units], the material shall be furnished in inch-pound units. 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.
