How does the Charpy impact test work?
In the Charpy impact test, W.S. Werkstoff Service tests a material's impact toughness using a sample prepared in accordance with the relevant standard. The sample is manufactured in accordance with DIN EN ISO 148-1 and provided with a V-notch. During the test, a pendulum hammer strikes the notched sample at the lowest point of its swing and breaks it. The energy consumed is recorded as the absorbed impact energy in joules. The measurements provide information on susceptibility to brittle fracture, toughness and temperature-dependent behaviour. By precisely controlling sample temperatures, the transition temperature can also be determined. Finally, the results are documented in a traceable manner.
