scope:

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 purposes of corrosion protection. It gives firstly the definition, classification and symbols for these 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 standard applies to thermalsprayed metallic coatings for the protection of iron and steel against corrosion by applying zinc or aluminium of 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 soe of the provisions are valid and may be adopted by agreement between the interested parties.
