Tinius Olsen’s popular model IT406 is a pendulum impact tester that can be easily changed from a Charpy configuration to an Izod configuration. These testers are designed primarily for determining the impact resistance of metals and are designed to fully comply with the specifications outlined in ASTM E23, EN ISO 148-3 and EN ISO 148-2.
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 5.47m/s (17.0ft/s) and has a maximum available energy of 406J (300ft.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.
