Specifies plating requirements and thickness classification for electro-deposited coatings of tin applied to fabricated articles of iron , steel and nickel alloys and copper and copper alloys containing more than 50 percent of copper. It also applies to coatings brightened by fusion in hot oil after electrodeposition. It does not provide for coatings on alloys based on magnesium, aluminium or zinc, coatings applied to sheet, strip or wire in unfabricated form or components having threads of basic major diameter up to and including 0.75 in. Heat treatment procedure of steels before and after plating is prescribed (where specified) and test methods covering local and average thickness adhesion, porosity, and solderability are given in appendices.
