These test specimens had metric instead of imperial (inches) dimensions. It has only a V notch. The Izod impact testing machine uses a farming hammer styled striker. The tests measure the amount of energy absorbed by a notched sample when it gets hit by a weighted pendulum. The two main types of impact testing using a pendulum are Izod and Charpy, both tests are very similar but there are notable differences: The Izod impact testing holds the sample vertically with the notch facing the pendulum. Izod and Charpy are impact strength measurement tests that produce a value that represents the amount of force an individual material can withstand. Specimen Dimensions The basic specimen size for Izod tests is 63.5 x 12.7 x 3.2 mm bar (for plastics) and 127 x 11.43 mm (round metal bar) The standard specimen size for Charpy tests is 10 mm x 10 mm x 55 mm (metal bar) Charpy Impact Test Conversion - CR4 Discussion Thread - GlobalSpec The Charpy impact testing holds the sample horizontally with the notch facing away from the pendulum. The system can test specimens with flat surfaces and thickness of 13 mm. Testers use a pendulum impact testing machine to perform the Charpy or the Izod impact test. Correlations like this can be useful for making rough estimations of impact strength results but the only way to determine the impact strength is to perform the testing using the method that you need. It is a simple and practical method of determining the strength and slope stability of rock, both in the field and in the laboratory. The system offers cutting edge features above and beyond the standard HPEII model.
