Evaluation of Two Cold Weather Gloves during Active Non-Contact and PassiveContact Activities

摘要

Handwear testing with human subjects is conducted primarily because measured dryinsulation values (IT) from models may not reliably predict actual thermal protection experienced in the field. Total clothing insulation, sweating, individual activity level or thermal contact with external objects also affect hand temperatures. In this study, the physiological of eight volunteer subjects wearing the Combat Vehicle Crewman cold weather (CVC) and Light Duty (LD) gloves were tested in an environmental chamber. The CVC glove is an insulated one piece glove of knit fire-retardent fabric with a leather reinforced palm. The LD glove is a two piece glove consisting of an uninsulated leather shell and a separate liner knit of wool and nylon. Glove total dry insulation (IT) values were measured on two biophysical hand models. IT for the knit fabric CVC glove was measured as 0. 16 m2KW (1.00 clo) and for the LD glove, IT was 0.12-0.14 m2 K W-1 (0.80-0.92 clo).
