GB/T 20624.1-2006 "Paints and varnishes - Rapid-deformation (impact resistance) tests - Part 1: Falling-weight test, large-area indenter" specifies a method for determining the impact resistance of paint films using a falling-weight test with a large-area indenter. It is applicable to various types of paint and varnish films. By adjusting the mass of the falling weight and the drop height, the indenter impacts the coated test panel, and the film is observed for cracking or peeling. The test requires equipment such as a falling-weight impact tester, a large-area indenter, and standard test panels to evaluate the ability of the paint film to withstand rapid deformation.
