As part of the L1939 Soldier's Helmet project, the Department of National Defence (DND) solicited bid submission for a new non-metallic, ballistic helmet for ground troops and parachutists. Six helmet models were recieved from five bidders on February 17 1995: SNC, Gallet, Expro/SNPE. Barrday/Gentex, and DEW, Humansystems Incorporated was tasked by DCIEM to undertake a limited trial of candidate helmets to assess their compliance with existing Human Factors (HF) requirements. HF requirements included fit, physical and thermal comfort, ease of use, hearing characteristics, stability and field of view. Compliance was determined in relation to the performance of the current in-service helmet (M1); for most aspects, candidate helmets were required to perform equally to or better than the M1 helmet. The results of this field trial will be used to assist the Soldier's Helmet project team in the bid evaluation process. A one week trial was conducted indoors to evaluate the six candidate helmets against the in-service M1 helmet. Thirty militia force soldiers, selected to represent a range of head sizes, were required to wear the M1 and each candidate helmet continuously for four hours of tests, including fitting and adjustment, obstacle course activities, physiclaly demanding tasks and focus group discussions. Field of vision testing was assessed separately using a peripheral vision rig. TRUNCATED
