1.1 本规范 2. 涵盖了一组通用要求，除非采购订单或单独规范中另有规定，否则这些要求应适用于ASTM发布的以下规范中的轧制钢板、薄板和钢带:规范 240米/240米 , A263 , A264 , A265 , a66 , A693 , A793 和 A895 . 1.2 如果产品规范的要求与本规范的要求之间存在冲突，应以产品规范为准。如果产品规范的要求或本规范的要求与采购订单的更严格要求之间存在冲突，应以采购订单为准。 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，则采购订单要求不应优先；例如通过放弃测试要求或通过降低测试要求的严格性。 1.3 以国际单位制或英寸磅单位表示的数值应单独视为标准。括号中显示了国际单位制，但当 480万 被指定， 附件A3 应适用于尺寸公差，而不是括号内的SI值 附件A2 .每个系统中规定的值不一定是精确等效的；因此，为了确保符合标准，每个系统应独立使用，并且不得将两个系统的值组合使用。 1.4 本规范和适用材料规范均以英寸磅和国际单位制表示。但是，除非订单规定了适用的“M”规格名称[SI单位]，否则材料应以英寸磅单位提供。 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 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.
