DIN EN 13523-21
Coil coated metals - Test methods - Part 21: Evaluation of outdoor exposed panels; German version EN 13523-21:2017
Bandbeschichtete Metalle - Prüfverfahren - Teil 21: Bewertung von freibewitterten Probenplatten; Deutsche Fassung EN 13523-21:2017
Overview
This standard specifies the procedure for evaluating the behaviour of an organic coating on a metallic substrate during and after outdoor exposure. Panel design, preparation and the procedure for outdoor exposure are performed in accordance with EN 13523-19. After washing of the panel, some dirt can remain on the panel. This remaining dirt can influence the accuracy and precision of readings of gloss and colour, performed on exposed panels, although carried out in accordance with the standards. Unlike other precise measurements, the objective of this part of EN 13523 is to report on trends in the corrosion and/or paint degradation behaviour of coil coated panels. This 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).
