1.1 本规程描述了可用于修复在热浸镀锌之前制造的硬件、结构形状和其他产品上损坏的热浸镀锌涂层以及初始热浸镀锌后剩余的未涂层区域的方法。损坏可能是焊接或切割（火焰）造成的，在这种情况下，涂层主要会因燃烧而损坏。这种做法也可用于修复在运输或安装过程中因过度粗暴搬运而损坏的热浸镀锌涂层。初始热浸镀锌后剩余未涂层区域的修复要求包含在适用的材料规范中。 1.2 本规程描述了使用低熔点锌合金修复棒或专门为此目的制造的粉末，使用含锌粉的油漆，以及使用喷涂锌（金属化）。 1.3 修理范围应限于缔约方双方同意的区域。 同样，缔约方应同意使用的维修方法。 1.4 单位- 本规范适用于以英寸-磅为单位的订单（如 A780型 )或使用国际单位制（如 A780米 ). 英寸-磅单位和国际单位不一定完全等同。在本规范文本中，如适用，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。 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。 1.6 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 practice describes methods that may be used to repair damaged hot-dip galvanized coatings on hardware, structural shapes, and other products fabricated prior to hot-dip galvanizing, and uncoated areas remaining after initial hot-dip galvanizing. The damage may be the result of welding or cutting (flame), in which case the coating will be damaged predominantly by burning. This practice can also be used to repair hot-dip galvanized coatings damaged by excessively rough handling during shipping or erection. Requirements concerning the renovation of uncoated areas remaining after initial hot-dip galvanizing are contained within the applicable material specification. 1.2 This practice describes the use of low melting point zinc alloy repair rods or powders made specifically for this purpose, the use of paints containing zinc dust, and the use of sprayed zinc (metallizing). 1.3 The extent of repair shall be limited to an area mutually agreeable to the contracting parties. Similarly, contracting parties shall agree to the repair method to be used. 1.4 Units— This specification is applicable to orders in either inch-pound units (as A780 ) or in SI units (as A780M ). 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. 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.
