Coil coated metals - Test methods - Part 21: Evaluation of outdoor exposed panels EN 13523-21:2003

Publication date:   Jun 30, 2004

Scope

This Part of 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 to be 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 this European Standard is to report on trends in the corrosion and/or paint degradation behaviour of coil coated panels.
