    Abstract - (Show below) - (Hide below)

    Covers the method of application, classification (into two classes and four types) and requirements (general, adhesion of coloured coatings and corrosion resistance).

    Scope - (Show below) - (Hide below)

    This International Standard specifies requirements relating to chromate conversion coatings on zinc and cadmium intended to give protection against corrosion. Finishes for giving particular colours only or specifically to improve paint adhesion are not covered by this International Standard.
