Product Description

CCSi features provides this reliable, direct reading Izod 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 cantilever 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 Izod Test (ASTM D256 Methods A, C, D and E and ASTM E23) test, the notch produces a stress concentration which promotes a brittle, rather than a ductile, fracture.

“The notch in the Izod specimen serves to concentrate the stress, minimize plastic deformation and direct the fracture to the part of the specimen behind the notch. Scatter in energy-to-break is thus reduced.”
(ASTM D256, Section 1, Note 2.)

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.
