ISO 6270-1:2017 PDF

Scope: This document specifies a method for determining the resistance of paint films, paint systems and related products to conditions of condensation in accordance with the requirements of coating or product specifications. 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 the performance likely to be obtained under severe conditions of exposure where continuous condensation occurs on the surface. The procedure can reveal failures of the coating (including blistering, staining, softening, wrinkling and embrittlement) and deterioration of the substrate. NOTE The shape and preparation of the test specimens, the duration of the test and the assessment of the test results are not covered by this document.
