Abstract
The international Technical report , ISO/TR 11079, will soon be due for revision. The report suggests that thermal insulation values from a moving thermal manikin can be used to match requirements specified by the IREQ-method. It is known from prior work that insulation values measured with human subjects can be reduced by up to 70 % from the value measured on a standing thermal manikin.
This paper deals with how the wind and walk reduction can be used for evaluation of work clothing with the modified IREQ method. The modified method has been used to evaluate three different ensembles that will be used by Swedish police on the Øresund bridge between Sweden and Denmark.
Results from calculations at different metabolic rates, wind speeds and temperatures are presented and compared with values measured on a thermal manikin. A new set of equations makes it possible to calculate the reduction of different activities and weather situations for most winter work clothing, if the static clothing insulation is known from manikin measurements or tables. To validate these relationships more measurements on subjects exposed to wind and motion in working life are needed.
