GB/T 20624.2-2006 "Paints and varnishes - Rapid-deformation (impact resistance) tests - Part 2: Falling-weight test, small-area indenter" specifies the method for determining the impact resistance of paint films using a falling-weight test with a small-area indenter. It is applicable to paint and varnish films. The principle is consistent with that of the large-area indenter test, with the only difference being the size of the indenter. This method places greater emphasis on evaluating the local impact resistance of the film. The test requires instruments such as a falling-weight impact tester, a small-area indenter, and a magnifying glass, providing a refined approach for assessing the impact resistance of paint films.
