UniTek™ Impact Testing Instruments by CCSi

CCSi features these reliable, direct reading Charpy and Izod Impact Testers for the determination of the resistance of plastics and metals to breakage by flexural shock as indicated by the energy extracted from a beam arm apparatus employing either a pendulum—type hammer (Charpy Model) or an adjustable combination cantilever—pendulum beam arrangement (Dual Model).
UniTek™ Charpy/Izod Impact Tester Model IT30 Dual
Model IT30 DUAL
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 self indexing mechanism which is released by the operating lever. The Dual Model features two starting positions, the uppermost for the Charpy Test (ASTM D256 and ASTM D6110) and the lower position for performing the Izod Test (ASTM D1822, ASTM D4508, ASTM D4812 and ASTM E23). The beam arm is mounted in frictionless bearings, providing high levels of reproducibility and repeatability.
The energy utilized to break the specimen is clearly indicated by the position of the maximum pointer against the dial. The Dual Model features two large angular scales with 2 J graduations, the innermost for the Izod Test and the outermost for the Charpy Test.
The UniTek™ IT30 Series Testers are ideally suited for:
  1. IT30 Dual: Charpy and Izod Tests;
  2. IT30 0.42: Izod Tests on plastics, ceramics, glass, etc.;
  3. IT30 1.4: Izod Tests on nonferrous metals & plastics;
  4. IT30 ASTM: ASTM E23 Charpy Tests.
