"GB/T 1732-2020 Method for Determination of Impact Resistance of Paint Films" is a standard for evaluating the impact performance of paint films. This standard replaces the GB/T 1732-1993 edition, and updates and perfects the test method by deleting and adding normative reference documents, modifying the provisions of impact testers, adjusting the size of the substrate and setting the impact point of the test plate. During the test, a fixed mass of heavy hammer is used to drop from a certain height. By gradually increasing the falling height to observe whether the paint film is crazing, wrinkling or flaking, to determine the impact performance of the paint film.
