The JB semi-automatic Charpy Impact Tester assesses the impact resistance of metal materials under dynamic loads, particularly suited for high-impact toughness ferrous metals like steel and its alloys. It measures absorbed work by comparing initial pendulum impact energy with post-impact residual energy, using a 150J/300J/500J pendulum for (10×10) mm samples.
