Model IT 542 Pendulum Impact Tester (High Capacity)

The Model IT 542 Impact, which shares all the same features as the Model IT 406 except that it has available energy of 542 J (400 ft•lbf). It is also supplied complete with the automatic motorized return, and digital display.
It provides maximum testing versatility. Easy insertion of interchangeable strikers in the pendulum head quickly adapts the machine for either Charpy or Izod testing. Two studs on the rear of the pendulum head allow optional tooling to be attached for performing tension impact tests.


A latch with a safety lock holds the pendulum in its raised position and assures a vibration-free release when activated. Once released, the pendulum quickly reaches the impact velocity of 5.47 m/s (17.0 ft/s) and has a maximum available energy of 542 J (400 ft•lbf) to impact the specimen


The superior design and construction of the Model IT 542 ensure maximum testing accuracy and repeatability. When the machine is properly installed and levelled, the total frictional and windage losses during the pendulum swing are guaranteed not to exceed 0.5% of the energy range.
