To conduct impact tests, devices which are used, the so-called impact hammers, enable the highforce application in a short period of time. Impact tests help to determine the resistance of the material to cracking at dynamic load. They are performed in order to determine the influence of the load speed and deformation on the mechanical properties of materials – they characterize the mechanical properties of the material that cannot be determined by static tests.
Pendulum impact machine Charpy Proeti 300J.
Instrumented pendulum machine Charpy Lab Test CHK 450J-I.
Tests can be carried out at the temperature to – 180ºC.
Impact tests can be performed for standard specimens 10x10x55 mm as well as smaller specimens of 7.5x10x55 mm and 5x10x55 mm.
To perform impact tests Institute is equipped with a standard Charpy pendulum machine as well as its instrumented version. It allows to determine not only the impact work, which is a measure of the material’s fracture toughness, but also to determine the characteristics of the breaking force as a function of time.
In addition, the laboratory has special digitally controlled chambers that enable tests to be conducted on specimens with reduced or increased temperature – a cooling chamber (specimens
cooled to a temperature of – 180 °C) and a heating chamber (tests up to a temperature of 300 °C).
