The purpose ASTM D4508 is to provide a test method for determining the impact strength of plastic materials with small samples of different thicknesses. This test method is meant to fill the gap left by Izod, Charpy, and drop-weight impact tests that limit the shape and thickness of the plastic specimen.
The impact test uses a small un-notched specimen that is impacted with a pendulum impact device. The pendulum impact device that is used to test with ASTM D4508 is the same as the Izod impact test machine. ASTM D256 defines the requirements of the Izod pendulum impact machine.
