1.1 本规范涵盖了热轧钢带卷和切割长度的一般要求。适用于热轧碳钢和高强度低合金钢。 1.2 本规范不适用于热轧厚碳钢板和带材卷（规范 A1018/A1018M )，冷轧碳素钢带（规格 A109/A109M )，高强度低合金冷轧钢（规格 A606/A606M 和 A1008/A1008M )或冷轧高碳钢（规格 A684/A684M ). 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下文所述的适当产品规范 2.1 ，数值应四舍五入至最接近的单位，位于根据实践四舍五入方法表示极限值所用数字的右侧 E29年 . 1.5 附件A1 列出了尺寸和质量的允许偏差( 注1 )以国际单位制[公制]为单位。列出的值不是英寸磅表中列出的值的精确转换，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: 当英寸-磅单位为标准单位时，使用术语“重量”；然而，在国际单位制下，首选术语是“质量” 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不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 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 hot-rolled steel strip in coils and cut lengths. It applies to carbon steel and high-strength, low-alloy steel furnished as hot-rolled. 1.2 This specification is not applicable to hot-rolled heavy-thickness carbon sheet and strip coils (Specification A1018/A1018M ), cold-rolled carbon steel strip (Specification A109/A109M ), high-strength, low-alloy cold-rolled steel (Specifications A606/A606M and A1008/A1008M ) or cold-rolled high carbon steel (Specification A684/A684M ). 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 under 2.1 , 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 . 1.5 Annex A1 lists permissible variations in dimensions and mass ( 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 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. 1.7 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.
