DIN EN 13523-12-2005 "Coiled metals in rolls, test methods, Part 12: Scratch resistance performance" This standard specifies the test method for determining the scratch resistance performance of organic coatings on metal substrates, which is applicable to coated metal materials in rolls. The resistance of coatings to penetrating damage is assessed by using a needle scratch coating. This method is particularly suitable for metal substrates with a thickness of less than 0.4 mm, such as aluminium alloys and thin gauge steels. The standard specifies the test equipment, specimen prepatives, test procedures and methods for evaluating results. It provides a scientific basis for the quality control and performance evaluation of metallic coatings. It is widely used in the construction, automotive and home appliances industries.
