Impact Performance of Football Helmets - Instron

To identify how the helmet will distribute the shock and absorb the energy from an impact, we set up a test on our CEAST 9350. The amount of force transmitted through the helmet is quantified with the Force Transmission Package. In this test, the helmet is installed onto a headform, which is then mounted onto a custom Piezo Compression Platen.
