Izod Impact Test

What Does Izod Impact Test Mean?

The Izod impact test is a standard test that measures the impact energy needed to fracture a material. This test helps engineers and scientists assess the fracture properties of a given part or component. The information obtained from the Izod impact test is used to determine how various materials will perform when subjected to impact loading.

Corrosionpedia Explains Izod Impact Test

To perform the Izod impact test, a V-shaped notch is first machined into the test specimen. An impact load is then applied via a hammer connected to a raised pendulum. When released, the hammer strikes the test specimen, which is fixed to the base of the testing machine.

The specimen fractures at the V-notch due to the impact force applied by the hammer. The impact energy is then calculated from the potential energy transferred from the load to the specimen.
