This European Standard specifies performance requirements for organic coating powders and powder organic coatings as applied to finished articles (galvanized or sherardized steel products) for construction purposes. This standard does not set out any performance requirements for the powder coating process itself. Galvanized steel products can be articles batch hot dip galvanized (galvanized after fabrication) or articles consisting of continuously hot-dip galvanized sheet which is then subsequently fabricated. This standard does not apply to articles with zinc-aluminium coatings or aluminium-zinc coatings, or to continuously hot dip galvanized wire. Guidance on cleaning and pre-treatment of the galvanized or sherardized steel products prior to powder coating is provided. NOTE This standard does not apply to organic coating powders and powder organic coatings as applied to galvanized or sherardized steel products (i.e. duplex coated articles) for which specific standards exist and which may include additional requirements or requirements which are different from those of this standard.
