The five hypothetical scenarios presented in Table 3 were obtained from ISO/DIS 7933:2018. As mentioned in Annex F of ISO/DIS 7933:2018, in all cases stationary or undefined walking conditions are assumed. Ta: air temperature; Tg: globe temperature; Va: air velocity; RH: relative humidity; M: metabolic rate; W: effective mechanical power; Icl: clothing insulation; Tr: mean radiant temperature; Pa: vapor pressure; Ap: fraction of the body surface area covered by reflective clothing; Fr: emissivity of the reflective clothing.
