It is commonly used for the soles and heels of footwear. In the Izod method, the striking point is on the upper. The Doctor has always been intrigued by the question of how to compare the impact values obtained by Izod testing methods with those of Charpy testing methods. The Izod impact strength test is an ASTM standard method of determining the impact resistance of materials. If you are unaware, there are two sets of test methods that are currently in use for many of the common tests that we see reported on data sheets and certificates of analysis. Discussion within ASTM Standard E 23[7] notes the following in regard to the comparison of Izod and Charpy data, namely: General correlation between the energy values obtained with specimens of different size or shape is not feasible, but limited correlations may be established for specification purposes on the basis of special studies of particular materials and particular specimens.. The Charpy impact test is still one of the most popular impact test methods. Position of Notch The notch in the Izod test is. For the Charpy tester, the notch is facing away from the pendulum arm. It specializes in different methods of speci-men preparation including cutting, polishing and grinding. I often see results listed in more significant figures than are allowed by the test method.
