Impact strength of plastics - Charpy and Izod methods
The impact strength of rigid plastics can be measured with the Charpy and Izod methods. In these tests, a pendulum is used to break the sample specimen. 10 specimens are needed for both tests.
This measurement covers impact testing with either Charpy (ISO 179) or Izod (ISO 180). Please specify the preferred method upon ordering.
The most significant difference between the Charpy and Izod methods is the placement of the specimen. In the Izod test, it is placed vertically and the notch is on the pendulum's side, while the Charpy test specimen is horizontal and the notch is on the opposite side of the pendulum. Testing can also be performed without a notch.
Sample preparation can be purchased separately.
