The GB/T 20624.2-2006 standard describes the rapid deformation (impact resistance) test method for Paints and varnish, in particular the use of drop weight test to evaluate the impact resistance of coatings. The tolerance of coatings is tested by applying a certain height of drop weight Impact to coatings with a small area punch. This method helps to understand the performance of coatings under impact loads in actual use, ensuring their Reliability and durability under various application conditions.
