What is BS EN 13523-21- Test methods of evaluation of outdoor exposed panels about?
BS EN 13523-21 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 BS EN 13523-21. 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 BS EN 13523-21 is to report on trends in the corrosion and/or paint degradation behaviour of coil coated panels.
Who is BS EN 13523-21- Test methods of evaluation of outdoor exposed panels for?
BS EN 13523-21 on Test methods of evaluation of outdoor exposed panels is useful for:
- Coil coated metal industries

What’s changed since the last update?
BS EN 13523-21:2017 supersedes BS EN 1352321:2010. BS EN 13523-21:2017 includes some technical changes with respect to BS EN 1352321:2010. These include:
- A “terms and definitions” clause has been added containing all terms and definitions from EN ISO 4628-8 and a definition for edge
- “Corrosion” and “delamination” was changed to “corroded area” and “delaminated area”, where appropriate
- The first inspection after 6 months was deleted
- The inspection of defects using a × 10 magnification was amended
- A reference to EN ISO 4628-8 was amended for evaluation of delamination and corrosion around the scribe
