The Ballistic Load Sensing Headform (BLSH) designed originally to evaluate the severity of behind armour blunt trauma for ballistic helmets is now being considered for assessing the dynamic loading pattern of Kinetic Energy Non-Lethal Weapons (KENLW). 20 different projectiles simulating KENLW impact conditions were launched at different velocities on the BLSH mounted on flexible and rigid necks to assess injury potential. In general, a good correlation was observed between the peak total force measured with the BLSH and the projectile velocity. The results indicated that most of the KENLW conditions tested were severe, and most likely would have caused injury. No difference was noticed between the flexible and rigid neck configurations for similar impact conditions. Pre and post-test verification showed that the BLSH force response remained constant throughout this evaluation. The BLSH appears suitable for assessing the insult to the head caused by KENLW projectiles but future evaluations must be limited to a maximum peak total force of 15 kN to preserve the integrity of the measured responses and to reduce the risk of equipment damage.
