ActivePaints and varnishes - Rapid-deformation(impact resistance) tests - Part 2: Falling-weight test,small-area indenter
色漆和清漆 快速变形(耐冲击性)试验 第2部分：落锤试验（小面积冲头）
Application Summary AI generated
This standard specifies a falling-weight test method using a small-area indenter to evaluate the impact resistance of paint and varnish coatings under rapid deformation. It is applied in quality control and material testing for coatings on metal substrates, such as automotive body panels, appliance housings, and industrial equipment, where resistance to mechanical impact from dropped objects or debris is critical. The test helps manufacturers assess coating durability and adhesion under sudden, concentrated force.
