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
Dieser Teil von EN 13523 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 dieser Teil dieser Europäischen 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 partie de l’EN 13523 spécifie le mode opératoire permettant d’évaluer le comportement d’un revêtement organique sur un subjectile 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 qui subsiste 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 partie de l’EN 13523 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.

EN 13523-21:2010 (E) 5 1 Scope 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

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.

EN 13523-21:2010 (E) 6 Where possible, the results of symmetrical areas, e.g. left and right edges, are combined and the average value is reported. The inspection of the 45° panel (panel 1) will focus on paint degradation, whereas the 90° panel (panel 2) and the 5° panel (panel 3) are mainly evaluated for corrosion. NOTE 1 Panel designations (1, 2, 3) are as defined in EN 13523-19. NOTE 2 Due to restrictions in the available flat area, the number of recommended readings might vary from other parts of EN 13523 and relevant EN ISO Standards. NOTE 3 It is strongly recommended to take a photograph of each exposed panel at each inspection. 5 Apparatus and materials 5.1 Gloss meter, in accordance with EN 13523-2. 5.2 Apparatus for colour measurement, in accordance with EN 13523-3. 5.3 Apparatus for measurement of chalking, in accordance with EN 13523-14. 5.4 Washing solution, containing 0,5 % (by mass) of a mild non-reactive detergent (pH 6 to 7) in water. 5.5 Cloth or sponge, non-abrasive and smooth. 6 Sampling See EN 13523-0. 7 Test panels See EN 13523-0. 8 Procedure 8.1 General Evaluate the coating properties at ambient temperature. The panels should be inspected not less than every six months in the first year and yearly afterwards. Colour measurements on metallics as well as gloss and colour measurements on textured and embossed surfaces are only indicative. 8.2 Preparation 8.2.1 Ensure that results of the measurements of gloss in accordance with EN 13523-2 and colour in accordance with EN 13523-3 are available before exposure of the test panels. When using reference panels, these panels shall be kept in an envelope and not exposed to any light source. 8.2.2 Some measurements require a washed area prior to inspection. Washing shall be performed as follows: Wash the upper 1/3 part of the 45° panel with washing solution (5.4) at ambient temperature (see Note). Use the cloth or sponge (5.5) to gently clean the surface. Rinse with water at ambient temperature an
