适用范围：This international Standard specifies requirements for electroplated silver and silver alloy coatings forelectrical, electronic and other engineering applications, including test methods. Engineedng applications aredefined as those in which the coating essentially serves a non-decorative purpose.Although this International Standard does not specify the condition, finish or surface roughness of the basismatedal pdor to electropleting, the appearance and serviceability of eleetroplated silver and silver alloycoatings depend on the condition of the basis material. It is essential that the purchaser specifies the surfacefinish and roughness of the basis material in order to conform to the product requirements,This International Standard does not apply to coatings on screw threads or to coatings on sheet, strip or wirein the non-fabricated form
