Biophysical Model for Handwear Insulation Testing
Abstract
Biophysical models of hands, feet and full manikins are used for direct measurement of clothing insulation. In this study, thermal resistance values (M2/KW) were measured with a weather resistant and simplified 7 zone hand model with upgraded controls and then compared to values from a 22 zone articulated copper model. Insulation is calculated from the power demand required to maintain a selected surface temperature set point at a known thermal gradient between the surface set point and the environment. For the new model, dry insulation values were 0.21 M2/KW for the standard military trigger finger mitten and 0. 1 2 M2/KW for the light-duty shell. Values for the 22 section copper hand model were 0.23 and 0.14 m2/KW, respectively. Both hand models provide replicable measurements of relative total handwear insulation....
