ISO FDIS 1518-2010 Scratch testing for Paints and varnishes is a draft international standard that specifies the method for evaluating the scratch resistance performance of Paints and varnishes coatings by scratch testing. The standard describes in detail the requirements for test equipment, test procedures, applied loads and determination of results, with the aim of ensuring the repeatability and comparability of test results. Scratch testing is used to evaluate the adhesion, hardness and surface integrity of coatings under external force, providing a scientific basis for the development, quality control and performance evaluation of coating materials. This standard is particularly applicable to the application scenarios of industrial coatings, decorative coatings and varnishes. It is an important reference document for measuring the Mechanical Properties of coatings and helps to improve the performance and reliability of Coatings products.
