This part of EN 13523 defines terms of the procedure for determining the resistance of an organic coating on a metallic substrate to humid atmospheres containing sulfur dioxide. Previous work by the European Coil Coating Association (ECCA) has established that this test method is not a reliable or reproducible test for assessing the degree of corrosion on coil coated products, but that the test method may be used to evaluate the colour fastness of coil coated products. The procedure has been aligned with EN ISO 3231, except for the amount of sulfur dioxide.
