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.
Impact strength (Charpy and Izod):
- MSZ EN ISO 179-1

Impact resistance (Dynstat):
- DIN 53435 (Not Accredited Measurement)
Impact resistance by the free-falling dart:
- MSZ ISO 7765-1 A method
