1.1 本规范涵盖了在钢铁基金属上机械沉积锌涂层的要求。涂层的厚度可达107μm，包括107μm。七种最厚的涂层通常被称为“机械镀锌” 1.2 单位- 以国际单位制表示的数值应视为标准。为了便于参考，给出了国际单位制的英寸-磅当量。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 注1: 该涂层的性能符合规范的要求 A153/A153M 和MIL-C-81562。 1.4 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 requirements for a coating of zinc mechanically deposited on iron and steel basis metals. The coating is provided in several thicknesses up to and including 107 μm. The seven thickest classes are usually referred to as “mechanically galvanized.” 1.2 Units— The values stated in SI units are to be regarded as the standard. The inch-pound equivalents of SI units are given for informational purposes. 1.3 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. Note 1: The performance of this coating complies with the requirements of Specification A153/A153M and MIL-C-81562. 1.4 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.
