indice de température au thermomètre-globe mouillé

CONT: L'effet combiné des facteurs environnementaux (température de l'air, humidité relative et circulation de l'air) s'exprime par l'indice de température au thermomètre-globe mouillé, souvent appelé l'indice WBGT. Cet indice sert à mesurer le stress thermique en ce qui a trait aux expositions professionnelles.
OBS: indice WBGT : L'abréviation «WBGT» provient du terme anglais «wet-bulb globe temperature».

CONT: The wet-bulb globe temperature (WBGT) index was originally developed based on the weighting of three environmental parameters: dry-bulb temperature, wet-bulb temperature and black globe temperature. A shielded dry-bulb thermometer, a natural wet-bulb thermometer and a globe thermometer (a black globe heated by solar radiation) are used to capture these environmental parameters. The WBGT index was later standardized ... and is now widely used as a heat stress index throughout the world, with the guidelines and permissible threshold limits in many industries, including construction and underground mining operations, being based on this measure.
