1.1 本规范涵盖复相（CP）级、双相（DP）级和相变诱发塑性（TRIP）级钢板，通过在线圈和切割长度中的热浸镀锌（镀锌）或锌铁合金涂层（镀锌）。 1.2 该产品以各种锌或锌铁合金涂层质量或涂层名称生产，如 表1 . 1.3 根据本规范提供的产品应符合最新版规范的适用要求 A924/A924米 ，除非本文另有规定。 1.4 该产品有多个名称和等级，具有强制性化学要求和强制性机械财产，通过热处理或热机械处理实现，并设计为与汽车应用要求兼容。 1.5 该产品的牌号命名法不同于其他具有强制性机械财产的热浸镀锌板产品，因为其顺序是拉伸强度值，而不是屈服强度值。 1.6 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.7 本规范的文本引用了提供解释性材料的注释和脚注。除表和图中的注释和脚注外，这些注释和脚注不应被视为本规范的要求。 1.8 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.9 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 steel sheet, complex phase (CP) grade, dual phase (DP) grade, and transformation induced plasticity (TRIP) grade, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process in coils and cut lengths. 1.2 The product is produced in various zinc or zinc-iron alloy-coating masses or coating designations as shown in Table 1 . 1.3 Product furnished under this specification shall conform to the applicable requirements of the latest issue of Specification A924/A924M , unless otherwise provided herein. 1.4 The product is available in a number of designations and grades with mandatory chemical requirements and mandatory mechanical properties that are achieved through thermal or thermal-mechanical treatments, and are designed to be compatible with automotive application requirements. 1.5 The grade designation nomenclature of the product differs from other hot-dip sheet products having mandatory mechanical properties in that ordering is to tensile, rather than yield strength values. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this specification. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 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.
