DIN EN ISO 27874-2009 金属和其它无机镀层.电气、电子和工程用电镀金和金合金镀层.规范和试验方法
Metallic and other inorganic coatings - Electrodeposited gold and gold alloy coatings for electrical, electronic and engineering purposes - Specification and test methods (ISO 27874:2008); English version of DIN EN ISO 27874:2009-01
This International Standard 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.
