Abstract
The aim of the proposed programme is to establish a research facility for the development and testing of a varity of protective garments. The facility will comprise a climatic chamber capable of simulating a range pf ambient conditions (temperature from -30 degrees C to +50 degrees C and relative humidity from 20% to 90%) and a variety of thermal manikins and models: a skin model, an immersion thermal manikin, an articulated sweating thermal manikin, an articulated sweathing thermal foot model and an articulated sweating thermal hand model. The developed manikins and skin, hand and foot models will provide data regarding the biophysical properties of fabrics and protective garments. Specifically the resistance
to heat and moisture transmission through the fabrics (skin model) and heat and moisture exchange between the clothing microenvironment and the surrounding ambient (thermal manikins, foot and hand model).
The skin model will be a 400cm2 guarded stainless steel hot plate simulating the dry and evaporative heat exchange occurring at the skin surface. The heat and water vapour resistance of test fabrics and multi-layer fabric assemblies will be determined by measuring the temperature and water vapour gradients across the fabrics, from the skin to the external environment. The climatic chamber will allow these biophysical properties to be determined over a rage of environmental conditions.
The water perfused immersion thermal manikin will allow the determination of the insulation value of immersion protective garments both in normabaric and hyperbaric conditions. Protective clothing for air ambients will be tested with the articulated sweating manikin. The manikin will be able to simulate gait and corresonding movements of the arms. The heat and water vapour resistence of test garments will be determined in a simular manner as with the skin model.
The articulated electrically heated and robot controlled sweating foot model will determine the temperature and water vapour resistance of test footwear during simulated walking, runnong, skiing and skating. The electrically heated sweating hand will be capable of clenching actions. The resistance to heat and water vapour transmission of protective hand wear will be determined during a pre-programmed series of clenching maneuvers in a selected range of ambient conditions.
The values derived from the above tests will be also be used to predict the comfort levels of the wearers for the anticipated range of activities un the ambient conditions tested.
The proposed facility will provide testing of prototype protective garments according to international standards, and will also enable the development of optimal protective clothing for a particular environment.
