IS 1572 : 1986 Specification for Electroplated Coatings of Cadmium on Iron and Steel

1 Scope

1.1 This standard covers requirements for electrodepositedcadmium coatings applied to iron or steel articles except forcoatings applied to components having threads of basic majordiameter from 1.25 to 12.5 mm and coatings applied to sheet or wirein the unfabricated form or to close-coiled springs.

1.2 Requirements are specified for appearance, thickness,adhesion, heat treatment before or after plating, precleaningstandards and if the coating is chromate-passivated, the corrosionresistance.
