Beschichtungsstoffe - Beurteilung von Beschichtungsschäden - Bewertung der Menge und der Größe von Schäden und der Intensität von gleichmäßigen Veränderungen im Aussehen - Teil 1: Allgemeine Einführung und Bewertungssystem (ISO 4628-1:2016); Deutsche Fassung EN ISO 4628-1:2016
Overview
This part of ISO 4628 defines a system for designating the quantity and size of defects and the intensity of changes in appearance of coatings and outlines the general principles of the system used throughout ISO 4628. This system is intended to be used, in particular, for defects caused by ageing and weathering, and for uniform changes, for example yellowing. The other parts of ISO 4628 provide pictorial standards or other means for evaluating particular types of defect. As far as possible, already existing evaluation schemes have been used as the basis. This part of ISO 4628 is also used for assessing defects not covered by the other parts of ISO 4628. The responsible German standardization committee is Working Committee NA 002-00-07 AA "Allgemeine Prüfverfahren für Beschichtungsstoffe und Beschichtungen" ("General test methods for coating materials and coatings") at DIN Standards Committee Coatings and Coating Materials (NAB).
