Specifies performance requirements for prepainted metal sheet and strip and organic file/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. Six product types and three surface finishes are specified. Appendices contain test methods and include atmospheric classifications and data on Australian and New Zealand corrosion test sites.

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 with an organic film, 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. It specifies three levels of coating finish.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 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 B).
