An interlaboratory study on measurements of clothing evaporative resistance with thermal manikins

Research output: Contribution to conferencePaper, not in proceeding


Abstract in Undetermined
An interlaboratory study on measurement of evaporative resistance (Ret) with thermal manikins has been conducted in order to assess the repeatability and reproducibility limits as a function of mean resistance values, when using similar test protocols (ASTM F2370). Three independent laboratories tested seven clothing ensembles, with Ret ranging from very low to very high values (20-325 m2∙Pa/W). The repeatability and the reproducibility limits were found to vary in the ranges 3-15% and 12-24%, respectively, for ensembles with a Ret value up to 60 m2∙Pa/W. These parameters escalated to 21-27% and 51-53%, for ensembles with higher Ret (110-325 m2∙Pa/W). The high relative error in the measurements of local manikin heat losses was found to play a relevant role, particularly for the most impermeable samples.
