Coil coated metals - Test methods - Part 18: Resistance to staining
This Part of EN 13523 specifies test procedures for assessing the effect of chemicals on the characteristics of an organic coating on a metallic substrate. It covers testing by using defined substances and to assess the change in characteristics such as discoloration, change in gloss, blistering, softening, swelling and loss of adhesion. Assessment of other phenomena may be agreed between the interested parties.
Bandbeschichtete Metalle - Prüfverfahren - Teil 18: Beständigkeit gegen Fleckenbildung
Dieser Teil von EN 13523 beschreibt Verfahren, mit denen der Einfluss von Chemikalien auf die Eigenschaften einer organischen Beschichtung auf einem metallischen Substrat abgeschätzt werden kann. Er schließt die Prüfung mit definierten Substanzen und die Bewertung von Eigenschaftsänderungen wie Verfärbung, Glanzänderung, Blasenbildung, Erweichen, Quellen und Haftfestigkeitsverlust ein. Andere Phänomene dürfen nach Vereinbarung zwischen den Vertragspartnern bewertet werden.
Tôles prélaquées - Méthodes d'essai - Partie 18 : Résistance aux taches
La présente partie de l'EN 13523 spécifie des méthodes d'évaluation de l'incidence des produits chimiques sur les caractéristiques d'un revetement organique appliqué sur un support métallique. Elle couvre les essais effectués avec des substances définies afin d'évaluer les changements de caractéristiques (décoloration, changement de brillant, cloquage, ramollissement, gonflement et perte d'adhérence). L'évaluation d'autres phénomenes peut faire l'objet d'un accord entre les parties.
