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.

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
