The Izod digital impact tester from TestResources is a low energy impact machine for testing the impact resistance of plastic specimens. The machine can be equipped with 5 different hammers to change the potential energy of the system. The machine features a digital controller that calculates impact energy and impact angle. The impact resistance can be used to determine impact stress by entering the specimen size into the machine. The machine used a non contact sensor to reduce friction while measure the angle of the arm, resulting in less than 2.5% energy loss. The machine is equipped with both a manual and automatic start. The 402J is also built to dampen out harmonic oscillations during the test.
