HFT – Helmet Fatigue Tester

Motorcycle helmet being tested for shell stiffnessThe Helmet Fatigue Tester (HFT) assesses the structural rigidity of a helmet or helmet component in any direction. It works by squeezing the helmet between two platens where the compression rate, measured force and number of compression cycles is computer programmed. The HFT has a peak compressive force of 4450 N (1000 lbf) and a maximum stroke length of 55 cm (22 in).
