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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

NOTE EN 15773 and EN ISO 12944-4 provide some guidance on surface conditions that might be encountered on post fabrication hot dip galvanised or sherardised articles. To achieve optimum quality of finished product, sharp edges on the fabrication should be avoided (see EN ISO 14713-2 and EN ISO 14713-3). 5 Coating powder 5.1 Identification The following information shall be made available by the supplier for each consignment of coating powder: a) manufacturer; b) trade name; c) colour; d) gloss level; e) type of resin; f) batch number; g) box number; h) product reference code; i) date of manufacture; j) date of despatch. 5.2 Storage The coating powder, after storage in unopened containers for a maximum period indicated by the manufacturer, calculated from the date of dispatch by the manufacturer, shall still conform to 5.3. If no maximum permissible storage period is indicated by the manufacturer, the coating powder shall, after storage in unopened containers for up to 12 months from the date of despatch by the manufacturer, conform to 5.3. The storage temperature shall not exceed 25 °C unless otherwise specified by the coating powder manufacturer. SIST EN 13438:2014
