This International Standard applies to electroplated coatings of not less than 99,5 % of tin on steel (or iron), and copper or copper alloys. It also applies to coatings brightened by fusion after electrodeposition, the process being known as flow-brightening (or flow-melting). It does not apply to
— coatings applied to machine screw threads (with tolerance);
— coatings applied to sheet, strip or wire in the unfabricated form, or to coil springs.
This International Standard does not specify the surface condition of the basis metal prior to piating; agreement on the degree of roughness which is acceptable shall be reached between the interested parties.
