Building materials, coating systems on exterior wood: Performance -accelerated test (NT BUILD 229)


  • This NORDTEST method specifies an accelerated performance test for paint coatings - expected to give maintenance intervals of at least 5 years on exterior woodwork, primarily joinery - for the purpose of evaluating their durability.

    Correlation with performance in use is still under evaluation and needs to be further supported by use of this test method.

Building materials, coating systems on materials: Resistance and protective value (NT BUILD 228)


  • The purpose of this Nordtest method is to examine the resistance to corrosion of metallic building materials protected by organic coating systems. The method is used to determine whether the resistance of a defined building material is sufficient to allow its use in a stipulated corrosive environment, ranging from no to very severe aggressiveness.
