1.1 本规范涵盖了含金量不低于99.00%且用于工程应用的电沉积金涂层的要求。 1.2 本规范特别排除了自动催化、浸渍和气相沉积金涂层。 1.3 符合本规范的金涂层用于其耐腐蚀和变色（包括耐微动腐蚀和催化聚合）、结合性、低且稳定的接触电阻、可焊性和红外反射率。 本规范涵盖了几种不同金纯度和硬度的涂层。 1.4 以国际单位制表示的数值应视为标准。括号中提供的值仅供参考。 1.5 以下危险警告仅适用于测试方法章节 9 ，本规范: 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 specification covers requirements for electrodeposited gold coatings that contain not less than 99.00 mass % gold and that are used for engineering applications. 1.2 Specifically excluded from this specification are autocatalytic, immersion, and vapor deposited gold coatings. 1.3 Gold coatings conforming to this specification are employed for their corrosion and tarnish resistance (including resistance to fretting corrosion and catalytic polymerization), bondability, low and stable contact resistance, solderability, and infrared reflectivity. Several types of coatings, differing in gold purity and hardness, are covered by this specification. 1.4 The values stated in SI units are to be regarded as the standard. Values provided in parentheses are for information only. 1.5 The following hazards caveat pertains only to the test methods section, Section 9 , of this specification: 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.
