CCSi features this reliable digital Charpy / 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 the beam arm apparatus employing an adjustable combination cantilever—pendulum beam arrangement for performing both Charpy and Izod Tests (ASTM D256, ASTM D1822, ASTM D4508, ASTM D4812, ASTM D6110 and ASTM E23).
The tests require specimens made with a milled notch, hence the test is often referred to as the “notched bar impact test”. In both the Charpy and Izod Tests, 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.
The beam arm is supported by a positive locking, self indexing, mechanism which is released by the operating lever. The IT30D features two starting positions, the uppermost for the Charpy Test and the lower position for performing the Izod Test. The beam arm is mounted in frictionless bearings, providing high levels of reproducibility and repeatability.
The IT30D is easily converted for either Izod or Charpy testing. Once configured, the test type is selected from the operating console. On completion of the test cycle, the energy utilized to break the specimen is clearly indicated on the large electronic digital display.
The operator is protected by an integral frame-style safety guard and the beam arm employs a braking arrangement to cease the pendulum motion after specimen rupture.
