Coil coated metals - Test methods - Part 21: Evaluation of outdoor exposed panels
This European 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 European Standard is to report on trends in the corrosion and/or paint degradation behaviour of coil coated panels.
Bandbeschichtete Metalle - Prüfverfahren - Teil 21: Bewertung von freibewitterten Probenplatten
Diese Europäische Norm legt das Bewerten einer organischen Beschichtung auf einem metallischen Substrat
während oder nach einer Freibewitterung fest. Die Maße der Probenplatte, Vorbereitung und Durchführung
der Freibewitterung müssen EN 13523-19 entsprechen.
Nach dem Waschen der Probenplatten kann etwas Schmutz auf der Probenplatte verbleiben. Bei Glanz- und
Farbmessungen an bewitterten Platten, obwohl normgerecht durchgeführt, ist deshalb nicht die gleiche
Genauigkeit und Präzision sichergestellt. Im Unterschied zu anderen genauen Messungen soll diese
Europäische Norm Tendenzen im Korrosions- und Abbauverhalten von Beschichtungen auf bandbeschichteten
Platten ermitteln.
Tôles prélaquées - Méthodes d'essai - Partie 21 : Évaluation des panneaux exposés en extérieur
La présente Norme européenne spécifie le mode opératoire à appliquer pour évaluer le comportement d’un
revêtement organique sur un support métallique durant et après exposition à l’extérieur. La conception des
panneaux, la préparation et le mode opératoire d’exposition à l’extérieur sont à réaliser conformément
à l’EN 13523-19.
Après lavage du panneau, il est possible que toute la saleté ne soit pas éliminée. La saleté résiduelle peut
influer sur la précision et la fidélité des lectures du brillant et de la couleur réalisées sur les panneaux
exposés, même si celles-ci sont effectuées conformément aux normes. Contrairement à d’autres mesures
fidèles, le but de la présente Norme européenne est de rendre compte des tendances observées concernant
le comportement à la corrosion et/ou à la dégradation de la peinture des panneaux prélaqués.
Kovine, prevlečene v svitkih - Metode preskušanja - 21. del: Vrednotenje preskušancev, izpostavljenih zunanjemu okolju
Ta evropski standard določa postopek za vrednotenje obnašanja organske prevleke na kovinskem substratu med izpostavitvijo zunanjemu okolju in po njej. Oblikovanje preskusnih ploščic, priprava in postopek za izpostavljanje zunanjemu okolju se izvajajo v skladu z EN 13523-19. Po spiranju ploščice lahko na njej ostane nekaj umazanije. Ta preostala umazanija lahko vpliva na točnost in natančnost odčitkov sijaja in barve, ki se izvajajo na izpostavljenih ploščicah, čeprav so opravljeni v skladu s standardi. V nasprotju z drugimi natančnimi meritvami je namen tega evropskega standarda poročati o trendih korozije in/ali obnašanju razpada barve na ploščicah, prevlečenih v svitkih.

Any degradation in the relevant area is reported, using the relevant parts of EN 13523 and appropriate EN ISO Standards. In cases where the inspection area is limited (e.g. at screws and bends), the evaluation method described in the EN ISO 4628 standard series is replaced by an easier and more suitable measurement of the degradation in millimetres.

c) Chalking Perform the measurement and report the results in accordance with EN 13523-14.
d) Cracking on the bend Inspect the bend visually for cracking. Report the presence of cracks as the distance, in millimetres, from the 1T side to the last sign of cracking.
e) Overall surface evaluation The overall surface is defined as the flat surface of panel 1 excluding edges and bends. Inspect the overall surface of the panel for blisters in accordance with EN ISO 4628-2, for cracking in accordance wit
