METHODS OF TEST FOR PAINTS AND VARNISHES : PART F2 : RESISTANCE TO HUMIDITY (CONTINUOUS CONDENSATION) (FIRST REVISION) (ISO 6270:1980, MOD)
1.1 This Malaysian Standard specifies a method for determining the resistance of paint
films, paints systems and allied products to conditions of high humidity.
t2 The method is applicable to coatings both on porous substrates such as wood,
plaster and plasterboard, and on non-porous substrates such as metal. It provides an
indication of performance likely to be obtained under severe conditions of exposure where
continuous condensation occurs on the surface.
t3 The procedure may reveal failures of the coating (including blistering, staining,
softening, wrinkling and embrittlement) and deterioration of the substrate.
