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

: To determine a metal's impact energy and strength, specifically to assess whether it behaves in a tough or brittle manner. It is often used to identify the ductile-to-brittle transition temperature (DBTT) . The standard, titled "Standard Test Methods for Notched
