Abstract

The instrumented Charpy impact test is used for determining properties related to the impact strength of plastics. It is an addition to the conventional pendulum impact test described in ISO 179 [1]; it is carried out on razor-blade-notched specimens. The plastics on which it can be used range from brittle thermosets to high-impact polymer blends. Both the load and the deflection signals are recorded, and the impact energy is divided into an elastic and a plastic part. If the requirements on the specimen size and on the notch are satisfied, geometry-independent material parameters can be calculated. These parameters can be used for control and for quality assurance as well as for research and development.
