DIN Standards Committee Coatings and Coating Materials

Overview

This International Standard specifies minimum thickness requirements for six classes of zinc diffusion layers applied to ferrous products by the sherardizing process for the purpose of protection against corrosion and wear. This International Standard does not specify any requirements for the surface condition (finish or roughness) of the basis material before sherardizing. Post-treatments (conversion coatings), after-treatments or organic over-coatings (Duplex) of sherardized articles are not in the scope of this International Standard. This International Standard does not apply to sherardized products (for example fasteners, tubes) for which specific standards exist and which might include additional requirements or requirements which are different from those of this International Standard. This document (prEN ISO 17668:2014-04) has been prepared by Technical Committee ISO/TC 107 "Metallic and other inorganic coatings", in collaboration with Technical Committee CEN/TC 262 "Metallic and other inorganic coatings", the secretariat of which is held by BSI (United Kingdom). The responsible German standardization committee is Working Committee NA 062-01-75 AA "Schmelztauchüberzüge" ("Hot dip coatings") at DIN Standards Committee Materials Testing (NMP).
