This International 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.
It 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.
It does not deal with repairs to damaged metal areas.
This International 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 the surface to be protected.
It does not, in general, apply to coatings obtained by the application of metals other than zinc or aluminium, although for other metals some of the provisions are valid and may be adopted by agreement between the interested parties.
