Replaceable shrouds prevent the specimen from rebounding against the pendulum. The striking bit is bolted to the pendulum and available in either 8 mm (ASTM E23) or 2 mm (BS, DIN, JIS, EN, and ISO) nose radius sizes. An optional set of self-centering tongs is extremely useful for accurately centering Charpy specimens, especially those subjected to temperature extremes prior to the test. Izod—The Izod striking bit is easily secured in the pendulum while the specimen is clamped in the close clearance slots in the vice. This ensures that the sample has the correct vertical alignment while the setting gage ensures that the sample is at correct height. A wrench is provided for tightening and loosening the sample in the vise. Tension Impact—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. The different configurations that are supported are as follows: Fig. 6. View of the Charpy striker from the pendulum head. Fig. 7. View of the base with the Charpy configuration. The sample rests horizontally on the Charpy anvils (obscured by the protective shrouds). Charpy centering tongs can be seen in front. Fig. 8. View of the Izod striker from the pendulum head. Fig. 9. View of the base with the Izod. The sample is clamped in the vertical position using the front screw. Fig. 10. View of the tension impact striker from the pendulum head. The sample is threaded into the ‘striker’ and the holding bar at the back of the pendulum head. Fig. 11. View of the base with the tension impact configuration.
