ASTM E23

ASTM E23 is a standard testing method used to evaluate the toughness and impact resistance of materials, primarily metals, by measuring their ability to absorb energy during sudden impacts. The most common test involves striking a standardized sample with a swinging pendulum and recording the energy required to cause fracture. This helps determine how materials will perform under real-world conditions, such as in crashes or heavy use, ensuring safety and durability in various applications. The standard provides consistent procedures to produce reliable, comparable results across different materials and manufacturers.
