EN 13523-21:2017

EN 13523-21:2017 is a standard published by the European Committee for Standardization (CEN). Its full title is "Coil coated metals - Test methods - Part 21: Evaluation of outdoor exposed panels". This standard covers: This part of the EN 13523 series 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.
