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.
