The EN 13523-4-2014 standard describes a pencil hardness testing method for evaluating the relative Hardness of organic coatings on metal substrates. The method uses a pencil with known Hardness to test on the coating surface to determine the Hardness grade of the coating. Suitable for smooth and textured surfaces, but textured surfaces may affect the accuracy of the test results. Provides a convenient means of testing for the evaluation of coating Hardness.
