Bench scale tests are often used to measure the thermal insulation of protective clothing. The thermal insulation is one of the main parameters controlling the clothing thermal comfort and protective performance. A bench-scale system is developed to measure the heat transfer within a multi-layer fabric using a cone calorimeter. A model is then developed to calculate the thermal insulation in hot environments. This paper presents measurements of the thermal insulation of the multi-layer fabric for low intensity thermal radiation of 1-10 kW/m2. The tests show that the total thermal insulation decreases with increasing heat flux as the local resistances of the outer shell layer, the moisture layer and the thermal barrier layer decrease, while that of the inner layer increases at first and then decreases. The influence of the thermal radiation reflectivity can be neglected for low intensity thermal radiation less than 10 kW/m2.
