ISO 1461:2009 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:

sheet, wire and woven or welded mesh products that are continuously hot dip galvanized
tube and pipe that are hot dip galvanized in automatic plants
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 ISO 1461:2009.

After-treatment/ over-coating of hot dip galvanized articles is not covered by ISO 1461:2009.
