BS EN 13523-4-2001 《Coil coated metals — Test methods — Part 4: Pencil hardness》 Related products

BS EN 13523-4-2001 "Coil metal coating. Test method, Pencil Hardness", specifies the test method for evaluating the Hardness of metal-organic coatings on coils by pencil hardness testing. The standard specifies the specifications of the pencil used for testing, the operation steps and the determination rules for coating Hardness. The coating Hardness performance is quickly and intuitively tested by the scratch of the pencil on the coating surface. It provides a technical basis for evaluating the wear resistance and scratch resistance of the coil coating metallic coatings and helps to control the product mass.
