1.1 本规范涵盖了锌-5的要求 % 通过热浸工艺对钢铁产品进行铝涂层。涂层还可能包含除锌和铝之外的少量元素，这些元素旨在改善涂层产品的加工和特性。这些金属涂层包括锌-5 %-铝（Zn-5Al）、锌-5 %-混合稀土铝（Zn-5Al-MM）和锌-5 %-铝镁（Zn-%Al-Mg）。 1.2 本规范涵盖了未制造产品和制造产品，例如，组装钢产品、结构钢制造、热处理前已弯曲或焊接的大管- 浸渍涂层和由未涂层钢丝制成的钢丝制品。本规范还涵盖了在热浸镀锌之前制造成零件的钢锻件和铸铁件，或尺寸太大而无法离心（或以其他方式处理以去除多余熔池金属）的钢锻件和铸铁件。 1.3 本规范涵盖了装配式钢筋组件。 1.4 本规范适用于以英寸-磅为单位的订单（如 A1072 )或国际单位制（如 A1072M ). 英寸-磅单位和国际单位不一定完全等同。在本规范文本中，在适当的情况下，国际单位制显示在括号中。 每个系统应相互独立使用，不得以任何方式组合数值。如果订单采用国际单位制，则所有测试和检验均应使用与测试或检验方法等效的公制单位（视情况而定）。如果订单采用国际单位制，则应在下订单时向热浸镀膜机说明。 1.5 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 zinc-5 % aluminum coated, by the hot-dip process on iron and steel products. The coating may also contain small amounts of elements other than zinc and aluminum that are intended to improve processing and the characteristics of the coated product. These metallic coatings include zinc- 5 %-aluminum (Zn-5Al), zinc-5 %-aluminum-mischmetal (Zn-5Al-MM) and zinc-5 %-aluminum-magnesium (Zn- %Al-Mg). 1.2 This specification covers both un-fabricated products and fabricated products, for example, assembled steel products, structural steel fabrications, large tubes already bent or welded before hot-dip coating, and wire work fabricated from uncoated steel wire. This specification, also, covers steel forgings and iron castings incorporated into pieces fabricated, before hot-dip coating or which are too large to be centrifuged (or otherwise handled to remove excess molten bath metal). 1.3 Fabricated reinforcing steel bar assemblies are covered by the present specification. 1.4 This specification is applicable to orders in either inch-pound units (as A1072 ) or SI units (as A1072M ). Inch-pound units and SI units are not necessarily exact equivalents. Within the text of this specification and where appropriate, SI units are shown in parentheses. Each system shall be used independently of the other without combining values in any way. In the case of orders in SI units, all testing and inspection shall be done using the metric equivalent of the test or inspection method as appropriate. In the case of orders in SI units, such shall be stated to the hot-dip coater when the order is placed. 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.
