The Impact Tester is a widely used device for the coating and plastic industries. In both industries impact resistance is measured by a falling weight from a controlled distance. For plastic materials the force is increased until structural failure occurs. In the case of a coated surface, failure will appear as a crack in the paint film. The impact tester creates a deformation in the surface that can also be used to measure a coatings flexibility. BYK-Gardner offers a wide variety of models and accessories to comply with ASTM and ISO methods related to a resistance tester.
