The heat transferred through protective clothing under long wave radiation compared to a reference
condition without radiant stress was determined in thermal manikin experiments. The influence of clothing
insulation and reflectivity, and the interaction with wind and wet underclothing were considered. Garments
with different outer materials and colours and additionally an aluminised reflective suit were combined with
different number and types of dry and pre-wetted underwear layers. Under radiant stress, whole body heat
loss decreased, i.e., heat gain occurred compared to the reference. This heat gain increased with radiation
intensity, and decreased with air velocity and clothing insulation. Except for the reflective outer layer that
showed only minimal heat gain over the whole range of radiation intensities, the influence of the outer
garments’ material and colour was small with dry clothing. Wetting the underclothing for simulating sweat
accumulation, however, caused differing effects with higher heat gain in less permeable garments.
