Pendulum Impact Model IT 406

The Model IT406 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 406 J (300 ft•lbf) to impact the specimen

The superior design and construction of the Model IT406 ensures maximum testing accuracy and repeatability. When the machine is properly installed and leveled, the total frictional and windage losses during the pendulum swing are guaranteed not to exceed 0.5% of the energy range.

Tinius Olsen offers a number of options to make the operation of the impact tester easier—from a simple electric brake to slow the swinging pendulum to a stop, to an automatic motorized return, eliminating the need for any operator involvement other than releasing the pendulum. The digital display is included in this last option and provides the trigger to energize the motor, which catches the swinging pendulum at the optimal position and returns it to the latched starting point.
