Introduction to Charpy Testing Charpy impact testing is a(CIT) n ASTM standard fracture mechanics technique used to measure a material’s notch toughness at moderately high strain rates. It is defined by the ASTM standard E23 1, requiring a 55x10x10 mm beam with a 45°, 2 mm deep notch cut into the History of the Charpy impact test. The history of Charpy V-notch impact testing dates back to the early 1900s when French engineer Georges Charpy developed a standardized method for testing the impact toughness of materials, particularly metals. His work led to the creation of the Charpy impact test, which involved striking a standardized specimen with a .ISO 13802:1999, Plastics Verification of pendulum impact-testing machines Charpy, Izod and tensile impact-testing. 3 Terms and definitions For the purposes of this part of ISO 179, the following terms and definitions apply. . direction of blow parallel to the dimension b, with impact on the narrow longitudinal surface h l of the specimen (see .
