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 .
