In Test Methods A, C, and D, the notch produces a stress concentration that increases the probability of a brittle, rather than a ductile, fracture. In Test Method E, the impact resistance is .There are two main forms of impact test, the Izod and the Charpy test. Both involve striking a standard specimen with a controlled weight pendulum travelling at a set speed. The amount of energy absorbed in fracturing the test piece is measured and this gives an indication of the notch toughness of the test material.
Tensile impact test. For tensile impact tests the specimen and yoke are aligned in a jig and clamped together. Depending on the test method in use, the specimen plus yoke are clamped in either the pendulum or the tensile impact fixture. The appropriate templates are used to set up for the various ISO and ASTM specimen types.1.1 - Pendulum Impact Test The most common configuration for pendulum impact test are Izod and Charpy ones. The scope of these impact . The reversed notch impact resistance technique is obtained by reversing the specimen in the position of a notched specimen in the vice.
