Abstract - (Show below) - (Hide below)

Specifies performance requirements for prepainted and organic film/metal laminate products in sheet and strip form that are coated on one or both sides with an organic film, and that are intended for fabrication into products for use in the construction or finishing of buildings.

Scope - (Show below) - (Hide below)

This Standard specifies performance requirements for prepainted and organic film/metal laminate products in sheet and strip form that are coated on one or both sides, and that are intended for fabrication into products for use in the construction or finishing of buildings.The Standard classifies prefinished/prepainted metal products into six types according to their performance, in respect to durability and aesthetics, in environments of varying severity.NOTES:1 Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in the purchasing guidelines set out in Appendix A.2 To demonstrate a means of compliance to this Standard refer to Appendix B.3 The performance of a coating will be dependent on the corrosion resistance of the substrate in the particular environment and on climatic influences that directly affect the coating. Such influences include solar radiation and the presence of water vapour (see Appendix C).4 A guide for the safe application for paint products on metallic substrates is shown in Appendix M.5 Appendix N sets out an interim procedure for the testing durability and corrosion resistance in naturally unwashed areas.
