1.1 本指南涵盖了表面清洁和处理通过热浸法或电镀法生产的新的连续镀锌（镀锌）钢表面的各种方法。本指南仅适用于液体涂料和涂料产品应用的表面处理，不适用于粉末涂料应用。本指南涵盖了之前未在工厂进行处理的表面，以提供临时保护，防止水分污染，而不是容易去除的保护油（参见 附录X1 ). 对于通过批量加工生产的镀锌钢新产品或风化产品的表面处理，请参阅规程 D6386 . 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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。 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。 ====意义和用途====== 4.1 本指南描述了可用于制备新的镀锌表面以进行涂漆和改善油漆与锌表面的结合的程序。

1.1 This guide covers surface cleaning and various methods for treating new, continuous zinc-coated (galvanized) steel surfaces produced by either the hot-dip method or by electroplating. This guide is applicable to only surface preparation for application of liquid paint and coating products, and not for powder coating applications. This guide covers surfaces that have not been treated previously at the mill to provide temporary protection against staining by moisture other than by easily removed protective oils (see Appendix X1 ). For preparing surfaces of new or weathered items of zinc-coated steel produced by batch processing, refer to Practice D6386 . 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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. 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. ====== Significance And Use ====== 4.1 This guide describes procedures that can be used to prepare new zinc-coated surfaces for painting and improve the bond of paint to the zinc surface.
