1.1 本规范涵盖了钢卷和切割长度的一般要求。它适用于描述作为热轧板和冷轧板提供的碳钢、结构钢和高强度低合金钢（HSLA）的以下规范:规范 A414/A414M , A424/A424M , A606/A606M , A659/A659M , A794/A794M , A1008/A1008M , A1011/A1011M 和 A1039/A1039M . 1.2 本规范不适用于热轧厚碳钢板卷（规范 A635/A635M ). 1.3 如果要求有任何冲突，应以单个材料规范的要求为准，而不是本通用规范的要求。 1.4 为了确定是否符合本规范和中引用的适当产品规范 1.1 ，测量值、计算值或观察值应按照惯例的舍入方法舍入到用于表示极限值的数字右侧最近的单位 E29年 . 1.4.1 表中规定的有序值，如30到48之间或30到48之间（不包括48），涵盖了指定为30.1、30.01、30.001等的所有有序值，不包括48.000等，但不包括指定为30.000等或以下的有序值，也不包括指定为48.1、48.01、48.001等的有序值。 1.5 附件A1 列出了尺寸和质量的允许偏差（参见 注1 )以国际单位制[公制]为单位。列出的值不是英寸中列出的值的精确转换- 磅表，而是四舍五入或合理化的值。符合 附件A1 当使用“M”规范时，是强制性的。 注1: 术语 重量 当英寸-磅单位为标准单位时使用。然而，在国际单位制下，首选术语是 大量 . 1.6 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.7 本规范和适用材料规范均以英寸-磅单位和国际单位制表示。但是，除非订单中规定了适用的“M”规格名称（国际单位制），否则材料应以英寸为单位提供- 磅单位。 1.8 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》中确立的国际公认标准化原则制定的。

1.1 This specification covers the general requirements for steel sheet in coils and cut lengths. It applies to the following specifications that describe carbon steel, structural steel, and high-strength, low-alloy steel (HSLA) furnished as hot-rolled sheet and cold-rolled sheet: Specifications A414/A414M , A424/A424M , A606/A606M , A659/A659M , A794/A794M , A1008/A1008M , A1011/A1011M , and A1039/A1039M . 1.2 This specification is not applicable to hot-rolled heavy-thickness carbon sheet coils (Specification A635/A635M ). 1.3 In case of any conflict in requirements, the requirements of the individual material specification shall prevail over those of this general specification. 1.4 For the purposes of determining conformance with this and the appropriate product specification referenced in 1.1 , measured values, calculated values, or observed values shall be rounded to the nearest unit in the right hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29 . 1.4.1 Ordered values, identified in tables, specified such as over 30 through 48 or 30 exclusive to 48 inclusive, covers all ordered values specified as 30.1, 30.01, 30.001, etc., up to and including 48.000 etc., but does not cover ordered values specified as 30.000 etc., or less, nor does it cover ordered values specified as 48.1, 48.01, 48.001, etc. 1.5 Annex A1 lists permissible variations in dimensions and mass (see Note 1 ) in SI [metric] units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Conformance to Annex A1 is mandatory when the “M” specification is used. Note 1: The term weight is used when inch-pound units are the standard. However, under SI the preferred term is mass . 1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.7 This specification and the applicable material specifications are expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units. 1.8 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.
