Izod impact test
Quick Summary
The Izod test is a method used by engineers to assess a material's resistance to impact. This test is crucial for predicting how materials like metals and plastics will behave under real-world conditions.12
In the Izod test, a notched specimen of the material is held in a vertical position. A swinging hammer strikes the notched piece, and the amount of energy, measured in foot-pounds, required to fracture it is determined. This value indicates the material's impact strength. The test is named after E. G. Izod, an English mechanical engineer.12

In the Izod test, the specimen stands erect, like a fence post. Shape and size of the specimen, mode of support, notch shape and geometry, and velocities at impact are all varied to produce specific test conditions. Nonmetals such as wood may be tested as supported beams,…
