The Izod Test is a standardized method used to measure the impact strength of materials by striking a notched specimen with a pendulum. This test helps assess a material's ability to withstand sudden impacts, making it essential in industries like construction, automotive, and aerospace. The results provide critical insights into material toughness and durability, ensuring products meet safety and performance standards. By evaluating how materials respond to high-speed stress, the Izod Test plays a key role in material selection and quality control processes.
