Le présent document prescrit une méthode pour la détermination de la résistance d'un feuil de peinture, de systèmes de peintures et de produits assimilés à des conditions de forte humidité selon les exigences du revêtement ou les spécifications du produit.
La méthode décrite ci-après est une méthode purement comparative pour déterminer la résistance d'un feuil à des conditions de forte humidité. Elle est applicable aux subjectiles poreux et aux subjectiles non poreux.
<p>ISO 6270-1:2017 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.</p> <p>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.</p> <p>The procedure can reveal failures of the coating (including blistering, staining, softening, wrinkling and embrittlement) and deterioration of the substrate.</p> <p>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.</p>
