We can define the Charpy and Izod impact resistance with the help of different hammers (0,5-5,5 J).  The toughness depends of the parameters of specimen, the quality of the specimen, notched or unnotched.

By the determination of impact resistance by the free-falling dart we can determine the energy, that harms the sheet (which is thinner than 1 mm) with the free-falling dart.
