Key Differences Between Izod and Charpy Impact Tests: A Comparison The Izod and Charpy impact tests are both used to measure a material's toughness and resistance to impact fractures, but they differ in testing methods. In the Izod test, the specimen is held vertically, and a pendulum strikes a notched section at the top. In contrast, the Charpy test involves a horizontally supported specimen with the pendulum striking the center of the notched area. While both tests provide valuable data on material performance, the Charpy test is more commonly used due to its ease of specimen preparation. Understanding these differences helps in selecting the appropriate test for material evaluation. Read more:- https://www.testing-instruments.com/blog/difference-between-izod-and-charpy-impact-testing/
