Paints and varnishes - Evaluation of quantity and size of defects, and of intensity of uniform changes in appearance - Part 5: Assessment of degree of flaking (ISO 4628-5:2022)

This document specifies a method for assessing the degree of flaking of coatings by comparison with pictorial standards.
ISO 4628-1 specifies the system used for designating the quantity and size of defects and the intensity of changes in appearance of coatings. It also outlines the general principles of the system. This system is intended to be used, in particular, for defects caused by ageing and weathering, and for uniform changes such as colour changes, for example yellowing.

Beschichtungsstoffe - Beurteilung der Menge und der Größe von Schäden und der Intensität von gleichmäßigen Veränderungen im Aussehen - Teil 5: Bewertung des Abblätterungsgrades (ISO 4628 5:2022)

Dieses Dokument legt ein Verfahren zum Bewerten des Abblätterungsgrades von Beschichtungen durch Vergleich mit Bildern fest.
ISO 4628 1 legt ein System zum Bewerten der Menge und der Größe von Beschichtungsschäden sowie der Intensität von Veränderungen im Aussehen von Beschichtungen fest. Sie enthält ebenso die allgemeinen Grundsätze des Bewertungssystems. Dieses System ist insbesondere für Schäden gedacht, die durch Alterung und Bewitterung hervorgerufen werden, und für gleichmäßige Veränderungen wie Farbänderungen, zum Beispiel Vergilbung.

Peintures et vernis - Évaluation de la quantité et de la dimension des défauts, et de l’intensité des changements uniformes d’aspect - Partie 5: Évaluation du degré d’écaillage (ISO 4628-5:2022)

Le présent document spécifie une méthode d’évaluation du degré d’écaillage de revêtements par comparaison avec des étalons illustrés.
L’ISO 4628‑1 spécifie un système de désignation de la quantité et de la dimension des défauts, ainsi que l’intensité des changements d’aspect intervenant sur les revêtements. Elle expose également les principes généraux de ce système. Ce système est destiné à être utilisé, en particulier, pour les défauts causés par le vieillissement et les intempéries, ainsi que pour les changements uniformes tels que les changements de couleur, par exemple le jaunissement.
