Beschichtungsstoffe - Beurteilung von Beschichtungsschäden - Bewertung der Menge und der Größe von Schäden und der Intensität von gleichmäßigen Veränderungen im Aussehen - Teil 10: Bewertung der Filiformkorrosion (ISO 4628-10:2016); Deutsche Fassung EN ISO 4628-10:2016
Overview
This part of ISO 4628 specifies a method for assessing the amount of filiform corrosion developed from a scribed mark by measuring the length of the longest filament L and the most frequent length M of filaments. Pictorial examples provided in Annex A of this part of ISO 4628 illustrate different ratings for the length of the longest filament L and the most frequent length M of the filaments. A comparison of the test panels with the 12 pictures in Annex A does not supersede the obligatory numerical assessment (method 1 or 2). ISO 4628-1 shall be used for the system for assessing the amount and magnitude of coating damage and the intensity of changes in the appearance of coatings and the general principles of the system. The committee responsible for this standard is NA 002-00-07 AA "Allgemeine Prüfverfahren für Beschichtungsstoffe und Beschichtungen" ("General test methods for coating materials and coatings") of the Standards Committee Coatings and Coating Materials (NAB) at DIN.
