Sharpy & Izod Impact Tests

Sharpy & Izod Impact Tests

Principle: 

The impact resistance test determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material’s notch toughness and acts as a tool to study temperature-dependent ductile-brittle transition.

In case of Charpy or Izod, the impact is induced by a pendulum hammer on the sample. The residual energy of the hammer is measured.

Testing procedure: 

The impact test is performed on a standardized sample of 80 x 10 x 4 mm, with or without notch. The sample is placed in a frame and the pendulum is released.

The Charpy test is performed according to ISO 179, whereas the Izod test is performed according to ISO 180.

Testing applications: 

The obtained values are used for:

  • Quality control
  • Determination of the impact resistance of plastics
