1. In Izod Impact Testing Machine,  a single point test is conducted which  assesses a material’s resistance to impact from a swaying pendulum. 

2. Izod impact can be called as  kinetic energy needed to initiate fracture and continue the fracture until the specimen gets broke. 

3. Izod specimens are notched to prevent distortion of the specimen upon impression of the pendulum. 

4. This test can be used as a quick and easy quality control check to govern if a material meets definite impact properties or to analyse materials for general durability.
