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