ASTM E23 Notched bar impact test, Charpy & Izod - ZwickRoell : To determine a metal's impact energy and

: Results typically include absorbed energy, test temperature, and an examination of the fracture surface to determine the percentage of shear fracture. Critical Applications ASTM E23 Notched bar impact test, Charpy &

The standard, titled "Standard Test Methods for Notched Bar Impact Testing of Metallic Materials," is the primary guideline in North America for measuring the toughness and impact resistance of metals. It details the procedures for both Charpy and Izod impact tests, which evaluate how much energy a material absorbs during fracture when subjected to sudden, dynamic loads. Key Components of ASTM E23

: Components that must withstand high-speed impacts or extreme temperatures.
