Steel Industry Glossary › Charpy Impact TestWhat is the Charpy impact test and its significance in material selection? The Charpy impact test measures a material's toughness by assessing energy absorbed during fracture. Conducted per ASTM E23 and ISO 148-1 standards, the test involves striking a notched specimen with a pendulum. Results help predict failure risks in applications. Typical values for metals may range from 5 to 50 Joules, influencing design choices across industries.
Charpy Impact Test A standardized test measuring the energy absorbed by a material during fracture at specified temperatures. Critical for low-temperature service applications.
