Impact Testing

Model 304 ASTM

Surface coatings are often exposed to impacts and impact stress in real-world practice. These can lead to deformation of the substrate and affect the adhesion and cohesion of the coating. Ball impact testers are used to test the resistance, deformability and ductility of coatings and substrates. They can also test the adhesion of coatings. The ball impact test provides you with a test that can simulate this type of stress under standardized conditions. In this case, a defined weight, the sample-side end of which is designed as a ball head (for ASTM and ISO-1) or as a male tappet (for ISO-2) with a fixed diameter, is dropped onto the sample through a guide tube.
