Pendulum Impact Model IT 406

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, BS EN ISO 148-3 and BS 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 5.47 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.

Configuration

Charpy

The specimen rests horizontally on the Charpy supports. Centering tongs can be seen in front .

Replaceable shrouds prevent the specimen from rebounding against the pendulum. The striker is bolted to the pendulum and available in 8mm (ASTM E23) or 2mm (BS, DIN, JIS, EN, and ISO) nose radius sizes. An optional set of selfcentering tongs is useful for accurately centering specimens, especially those subjected to temperature extremes before the test

Izod

The specimen is clamped vertically at one end, using the front screw/vise. Left: The striker.

The Izod striker is easily secured in the pendulum while the specimen is clamped in the close clearance slots in the vise. This ensures the specimen has the correct vertical alignment while the setting gage ensures the specimen is at correct height. A wrench is provided for tightening and loosening the specimen in the vise.

Tension Impact

The specimen is threaded into the striker (left) and the holding bar at the rear of the pendulum head.

The tension impact specimen is threaded into the specimen holder in the pendulum head. Tension is instantaneously applied to the specimen when the holding bar strikes the anvils. This method of support provides uniform distribution of the impact energy over the cross-section of the test specimen.
