摘要

This study aimed to validate the summation methods suggested by ISO 9920.Twenty seven items from an ambulance personnel clothing system were selected for testing.The basic insulation of each garment item (Iclu)was calculated based on the thermal manikin tests. More than 100 realistic clothingcombinations were compiled and basic insulation(Icl) of these ensembles was calculatedaccording to ISO 9920. These were ranked after the calculated insulation, and 14 setscovering insulation from 0.63 to 3.33 clo were measured on the thermal manikin foracquiring the basic clothing insulation (Icl).Regression analysis was used to compare the summed and measuredIcl values. The difference between valuesvaried from −18 to 12%. The highest percentual difference was for the lightest clothingsets, while the absolute differences were similar over the whole insulation range rangingbetween −0.17 to 0.18 clo with an average difference of 0.02 clo (−0.16%). All basicinsulation values stayed very close to the line of identity (R2=0.98). Thesummation equation gave, in the case of this ambulance clothing system, very close resultsto the measured values. This encourages evaluating and selecting protective clothingcombinations for thermal comfort based on individual item measurements.
