Scope

This Standard applies to thermal-sprayed metallic coatings for the protection of
iron and steel against corrosion by applying zinc or aluminium or their alloys to
uncoated surface to be protected.
This Standard deals with characteristic properties and gives test methods for
coatings obtained by the spraying of zinc and aluminium and their alloys for the
general purpose of corrosion protection.
This Standard gives firstly the definition, classification and symbols for these
coatings in relation to their thickness. It then deals with the preparation of
surfaces, application of coatings and their characteristic properties: namely,
thickness, appearance and adhesion. Finally it gives test methods for checking
these properties.
For other metals some of the provisions are valid and can be adopted by
agreement between the interested parties.
