AS/NZS 4506:1998
Metal finishing - Thermoset powder coatings
Sets out test procedures and specifies performance requirements for thermoset powder coatings applied to metal substrates, with the exception of aluminium for architectural applications (see AS 3715). The Standard classifies service environments into five categories and specifies a minimum coating thickness for each category. Appendices give advice on surface pre-treatment prior to powder coating, weathering performance and maintenance of powder-coated metal.
