Interlaboratory tests on thermal foot models
Author
Summary, in English
In order to compare measurements in different laboratories and with different models and measuring principles a small Round Robin test was suggested. 12 test institutions were able to join the study (with foot model sizes from 254 mm to 275 mm and test boot sizes from 41 to 44). We got also a declaration of interest from 2 other institutes that were not able to carry out the tests now. A database was created for study results, thus making it possible to add test results from other test laboratories and on other footwear later on.
The test series were carried out under standardised conditions in each laboratory. Ten (10) test conditions were recommended. All conditions had to be tested twice. Tests with bare foot and sock were carried out at about +20 °C and 50 % RH. The other conditions 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). Participants were asked to carry out as many tests as they could from the list and skip those they were not able to do. If something in test conditions had to be changed, a note was made on that.
The test series was meant to be a basis for applying for a project further on that should aim to suggest changes in existing European standard (EN 344) or propose a new (international) standard on footwear thermal testing.
