Correction factors of ISO 7933, ISO 9920, and experimental results. a Correction factors of IT in terms of relative air velocity, b correction factors of ReT in terms of relative air velocity, c correction factors of IT in terms of walking speed, and d correction factors of ReT in terms of walking speed. The averages of intrinsic thermal insulation of the tested clothing used in the experiments were the following: a 1.1 clo (Havenith et al. [1] (cloth)), 0.0 clo (Qian and Fan [34] (nude)), 0.7 clo (Qian and Fan [35] (cloth)), 1.9 clo (Morrissey and Rossi [36] (Hi perm.)), 0.0 clo (Lu et al [37] (nude)), 1.8 clo (Lu et al. [37] (moderate)); b 1.1 clo (Havenith et al. [2] (cloth)), 0.0 clo (Qian and Fan [34] (nude)), 0.7 clo (Qian and Fan [35] (cloth)), 0.0 clo (Wang et al. [38] (nude)); c 0.0 clo (Lu et al. [37] (nude)), 1.5 clo (Lu et al. [37] (moderate)), 1.2 clo (Ueno and Sawada [39] (Workwear)), 0.7 clo (Qian and Fan [34] (Cloth)), 1.9 clo (Morrissey and Rossi [36] (Hi perm.)), 0.0 clo (Oliveira et al [40] (nude)); and d 0.0 clo (Wang et al. [38] (nude)), 1.1 clo (Havenith et al. [2] (cloth)), 1.2 clo (Ueno and Sawada [39] (workwear)), 0.0 clo (Qian and Fan [34] (Nude)), 0.7 clo (Qian and Fan [35] (cloth)). When only the total thermal insulation was given in the reference, the intrinsic thermal insulation was calculated using the equations in ISO 7933
