Penetration test

The instrumented test in accordance with this standard describes a test method that is used to determine the penetration behaviour of solid plastics.

An impactor is moved towards the test specimen at right angles at a constant speed and penetrates it. The test can be conducted within a temperature range from –40°C to +80°C.

Results of the test method
  • Force and deflection values such as:
    - Maximum force FM [N]
    - Deformation at maximum force IM [mm]
    - Energy to maximum force EM [J]
    - Puncture deflection lP [mm]
    - Puncture energy EP [J]
  • Stress-strain curve
