Scope

ISO 4521:2008 specifies requirements for electroplated silver and silver alloy coatings for electrical, electronic and other engineering applications, including test methods. Engineering applications are defined as those in which the coating essentially serves a non-decorative purpose.
Although ISO 4521:2008 does not specify the condition, finish or surface roughness of the basis material prior to electroplating, the appearance and serviceability of electroplated silver and silver alloy coatings depends on the condition of the basis material. It is essential that the purchaser specifies the surface finish and roughness of the basis material in order to conform to the product requirements.
ISO 4521:2008 does not apply to coatings on screw threads or to coatings on sheet, strip or wire in the non-fabricated form.
