Output

Impact energy, Impact strength

The impact test is a standardized method for analyzing the toughness or brittle-fracture sensitivity of a material.

Measurements are carried out with a Zwick/Roell HIT5.5P impact tester equipped with all hammers suitable for use with plastics. Measurements can be carried out at room temperature as per IZOD (ISO 180) or Charpy (ISO 179). The specimens can be notched with the help of a standardized notch-cutting machine.

The (notched) impact value is defined as the energy lost per unit of specimen thickness (at the notch).
