Abstract Correlations of pain threshold time ranging from 10 to 590s versus constant heat flow were determined on the thenar eminence (part of the palm) of 3 subjects. These data show that hands behave thermically as semi-infinite solids in the range 25 to 590s. The method consists of assessing the pain threshold time from the temperature rise which the surface of a semi-infinite solid would experience versus time. In the first version of the method the skin temperature rise is calculated from the recording of heat flow through the sample versus time under the same heat load. In the second version, the surface temperature rise of a block of nylon is measured. The skin temperature rise is 1.48 times less than the temperature rise of the block. Pain threshold was assumed to be reached at a skin temperature rise equal to 12°C. Both versions allow pain threshold time to be assessed directly in the range of 25 to 590s. For a time less than 25s, corrections using the correlation of Stoll and Greene are necessary. The first version of the test method can be extended to the gloves for protection against cold and the method of interpretation of results to the gloves for protection against convection or radiant heat.
