ISO/FDIS 1518-2010 Scratch testing for Paints and varnishes specifies a test method for evaluating the scratch resistance performance of Paints and varnishes coatings. The standard assesses the hardness and abrasion resistance of coatings by applying a scratch test of force to the surface of the coating to check for crazing, flaking or Miscellaneous damage. The standard describes in detail the test equipment, specimen preparation, methods for applying loads and criteria for evaluating results to ensure test accuracy and repeatability. This test is applicable to the quality control, performance evaluation and development process of various Coating systems, especially in Coating products requiring high abrasion resistance. This standard provides a unified test specification for the Coating industry, which helps to improve the mass and reliability of coating products.
