标准摘要
[中文适用范围]： 本国际标准规定了金属和非金属基材上用于电气、电子和其他工程应用的电镀金和金色合金镀层的要求。它还规定了测量镀层性能的测试方法。虽然本国际标准未规定电镀前基材的条件、表面光洁度或粗糙度，但电镀金或金色合金镀层的外观和适用性取决于基材的状况。必须规定基材的表面光洁度和粗糙度以符合产品要求。本国际标准不适用于螺纹件上的镀层，也不适用于未加工成型的板材或带材上的镀层。 [外文原描述]： ISO 27874:2008 specifies the requirements for electrodeposited gold and gold alloy coatings for electrical, electronic and other engineering applications on metallic and non-metallic substrates. It also specifies test methods for measuring the properties of the coatings. Although this International Standard does not specify the condition, finish or surface roughness of the basis material prior to electroplating, the appearance and serviceability of electroplated gold or gold alloy coatings depends on the condition of the basis material. It is essential that the purchaser specify the surface finish and roughness of the basis material in order to conform to the product requirements. This International Standard does not apply to coatings on threaded articles or to coatings on sheet or strip in non-fabricated form.
