| Heat stress index | Engineering & Technology | A single numerical value representing the combined effects of a variety of factors contributing to thermal stress. Source: European Union. (references) | |
| Heat stress index | Meteorology & Standards | An effective global index of hot environments taking into account the relationship between the required evaporation and the maximal evaporation possible in the environment. Source: European Union. (references) | |
| Heat stress index of Belding and Hatch | Meteorology & Standards | An expression based on the ratio of the sweat evaporation rate necessary to maintain thermal equilibrium at the maximum evaporative capacity of the environment. Generally used in the form E sub eq/E sub max x 1000, where E denotes evaporation. Thus, an HSI in excess of 100 indicates positive heat stress, a state of thermal imbalance. Source: European Union.
