Product Description

CCSi features this reliable, direct reading Charpy Impact Tester for the determination of the resistance of plastics and metals to breakage by flexural shock as indicated by the energy extracted from a simple beam apparatus employing a pendulum—type hammer.

The test requires specimens made with a milled notch, hence the test is often referred to as the “notched bar impact test”. In the Charpy Test (ASTM D256 Method B, ASTM D4508, ASTM D4812, ASTM D6110 and ASTM E23) test, the notch produces a stress concentration which promotes a brittle, rather than a ductile, fracture.

The results are reported in terms of energy absorbed per unit of specimen width, or more specifically, the energy absorbed in breaking the specimen which is equal to the difference between the potential energy at the moment of impact and the residual energy.
