Interlaboratory tests on thermal foot models
(2005) 10th International Conference on Environmental Ergonomics 3. p.449-457- Abstract
- A limited Round Robin test has been carried out with different types of foot models. Eight laboratories carried out the tests. The foot models varied in sizes from 254 to 275 mm, representing boot sizes from 41 to 44. Tests with both a bare foot and sock were carried out at about +20 °C and 50% RH. The boots, a thin rubber and a winter boot, were tested at about +5 °C and 85% RH. The conditioning was done at 20 +/- 2 °C and 35 +/- 5% RH. Air velocity was kept low (,0.3 m/s). Wet tests included simulation of sweating by supplying water to the foot skin at a rate of 5 g/h/foot. Relatively big inter-laboratory differences in measuring results were obtained. The differences were smaller for total insulation values but could be over 30% for... (More)

Wet tests included simulation of sweating by supplying water to the foot skin at a rate of 5 g/h/foot. Relatively big inter-laboratory differences in measuring results were obtained. The differences were smaller for total insulation values but could be over 30% for local zones. More elaborate comparative tests under different conditions and with more types of footwear need to be done. The effects of differences due to model construction, etc., should be analysed further. For standard use it is important to determine which zones should be included in the total insulation calculation and which zones should be reported separately, e.g. sole area. The foot construction, and the conditions, measurements and calculations for wet tests should be more clearly defined. (Less)
