Impact Testing on Polymers - Conventional and Instrumented


Pendulum impact testers determine the impact energy absorbed by a standardized specimen up to break by measuring the height of rise of the pendulum hammer after impact. The result is impact strength or notched impact strength, which is indicated in relation to area, for example in kJ/m². We will give an overview of the standard test methods (Charpy; Izod, Dynstat,…) and explain the difference between a conventional and instrumented impact test.
