Coil coated metals - Test methods - Part 18: Resistance to staining

This document 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 can be agreed between the interested parties

Bandbeschichtete Metalle - Prüfverfahren - Teil 18: Beständigkeit gegen Fleckenbildung

Dieses Dokument legt Verfahren fest, mit denen der Einfluss von Chemikalien auf die Eigenschaften einer organischen Beschichtung auf einem metallischen Substrat abgeschätzt werden kann. Es schließt die Prüfung mit definierten Substanzen und die Bewertung von Eigenschaftsänderungen wie Verfärbung, Glanz¬änderung, Blasenbildung, Erweichen, Quellen und Haftfestigkeitsverlust ein. Andere Phänomene können nach Vereinbarung zwischen den Vertragspartnern bewertet werden.

Tôles prélaquées - Méthodes d’essai - Partie 18 : Résistance aux taches

Le présent document spécifie des modes opératoires d’essai pour évaluer l’incidence des produits chimiques sur les caractéristiques d’un revêtement organique appliqué sur un subjectile métallique. Il 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 phénomènes peut faire l’objet d’un accord entre les parties intéressées.
