1.1 锌片涂层系统是锌片的流体分散体，有时添加铝片，其非电解地应用于钢基材。锌薄片涂层系统应不含六价铬，可以是水基或溶剂型系统。通过在固化过程中形成的基体实现锌片之间的内聚性和与钢基体的粘附。 1.2 本规范涵盖非电解应用锌的分类、性能和基本要求- 英制和公制系列螺纹紧固件上的片状涂层，英制系列的最小标称直径为0.250英寸，公制系列的最小公称直径为6毫米。 1.3 本标准是对三个ASTM标准的巩固和替代:规范 F1136/F1136米 , F2833 和 F3019/F3019M . 1.4 单位-- 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值不一定是完全相等的；因此，为了确保符合标准，每个系统应独立使用，并且不得将两个系统的值组合使用。 1.5 本标准并不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 Zinc-flake coating systems are fluid dispersions of zinc-flakes, sometimes with the addition of aluminum flakes, which are non-electrolytically applied to steel substrates. The zinc-flake coating system shall be supplied without hexavalent chromium and can be water based or solvent based systems. Cohesion among the zinc-flakes and adhesion to the steel substrate is achieved through a matrix that is formed during the curing process. 1.2 This specification covers the classification, performance, and basic requirements for non-electrolytically applied zinc-flake coatings on unified inch and metric series threaded fasteners with minimum nominal diameters of 0.250 in. for inch series and 6 mm for metric. 1.3 This standard is a consolidation and replacement of three ASTM standards: Specifications F1136/F1136M , F2833 , and F3019/F3019M . 1.4 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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.
