1.1 本规范涵盖通过热浸镀锌工艺在钢铁五金件上涂覆的锌涂层。热浸镀锌工艺包括将零件浸入熔融锌中足够长的时间，以使钢表面的铁和熔融锌之间发生冶金反应，从而形成将涂层结合到钢表面的Zn/Fe合金层。 1.2 本规范适用于离心或以其他方式处理以去除多余镀锌槽金属（游离锌）的五金件。涂层厚度等级要求反映了这一点。 1.3 必须符合《紧固件质量法》的紧固件需要在检查紧固件批次时进行特定的统计抽样。这些紧固件的取样要求见 F2329/F2329米 . 1.4 本规范适用于以英寸磅为单位的订单（如 第153页 )或国际单位制（如 1.53亿澳元 ). 英寸磅单位和国际单位制单位不一定是精确的等价物。在本规范的文本中，在适当的情况下，国际单位制单位显示在括号中。每个系统应独立使用，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方法进行。如果订单采用国际单位制，则应在下订单时向镀锌工说明。 1.5 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。 1.6 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 zinc coatings applied by the hot-dip process on iron and steel hardware. The hot-dip galvanizing process consists of parts being immersed in molten zinc for a sufficient time to allow a metallurgical reaction between iron from the steel surface and the molten zinc, resulting in the formation of Zn/Fe alloy layers bonding the coating to the steel surface. 1.2 This specification is intended to be applicable to hardware items that are centrifuged or otherwise handled to remove excess galvanizing bath metal (free zinc). Coating thickness grade requirements reflect this. 1.3 Fasteners that must comply with the Fastener Quality Act require specific statistical sampling during the inspection of the fastener lots. Requirements for the sampling of these fasteners can be found in F2329/F2329M . 1.4 This specification is applicable to orders in either inch-pound units (as A153 ) or in SI units (as A153M ). 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 brackets. 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 galvanizer when the order is placed. 1.5 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. 1.6 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.
