14、by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2003, and conflicting national standards shall be withdrawn at the latest by January 2003. According to the CEN/CENELEC Internal Reg

16、and the United Kingdom. Introduction 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 f
17、astness of coil coated products. The test method has been aligned with EN ISO 3231:1997, except for the amount of sulfur dioxide. 1 Scope This Part of EN 13523 defines terms of the procedure for determining the colour stability of an organic coating on a metallic substrate when exposed to humid atmo
18、spheres containing sulfur dioxide. This method has been designed to provide an accelerated test for evaluating the colour fastness of coil coated products in atmospheres containing sulfur dioxide (typical of industrial atmospheres). 2 Normative references This European Standard incorporates, by date
19、d or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard
20、only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).
