Covers requirements for electroplated coatings of nickel plus chromium and nickel both with a copper undercoat in some cases on steel or iron, zinc alloy, copper or copper alloys, except for coatings applied to machine screw threads, sheet, strip, wire in the unfabricated form, or coil springs, and those applied for engineering purposes. Includes examples of service conditions for which the various service condition numbers are appropriate, determination of nickel and copper thickness, ductility test, determination of chromium thickness-coulometric method, cracks and pores in chromium coatings, file test for adhesion, quenching test for adhesion, CASS test, corrodkote test, and acetic salt test.
