This International Standard specifies the general properties of coatings and test methods for coatings applied by dipping fabricated iron and steel articles (including certain castings) in a zinc melt (containing not more than 2 % of other metals). It does not apply to the following: a) sheet, wire and woven or welded mesh products that are continuously hot dip galvanized; b) tube and pipe that are hot dip galvanized in automatic plants; c) hot dip galvanized products (e.g. fasteners) for which specific standards exist and which might include additional requirements or requirements which are different from those of this International Standard. NOTE Individual product standards can incorporate this International Standard for the coating by quoting its number, or can incorporate it with modifications specific to the product. Different requirements can also be made for galvanized coatings on products intended to meet specific regulatory requirements. After-treatment/over-coating of hot dip galvanized articles is not covered by this International Standard.
