Impact tester: How to measure impact resistance

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 coating’s flexibility. BYK-Gardner offers a wide variety of models and accessories to comply with ASTM and ISO methods related to a resistance tester. More info: https://www.byk-instruments.com/en/Ph... Performing an impact test: Install the weight -- 1:11 Use appropriate weight, note falling height -- 1:19 Place test planel in the apparatus -- 1:29 Evaluate test result -- 1:45 _______________________ Methodologies: R&D grading test: Adjust height and weight to determine exact point of failure -- 1:50 Pass/fail test based on specification -- 1:58 Quality control: intrusion or extrusion -- 2:04 ______________________________ Impact test result -- 2:09
