Atmosphère Explosive ATEX; explosive armosphere ATEX
Mixture with air, under atmospheric conditions, of flammable substances in the form of gases, vapors or dusts in which, after ignition, combustion spreads to the entire unburned mixture.
Flash point
The lowest temperature of a liquid at which, under certain standardized conditions, it releases vapors in such quantities that a flammable vapor/air mixture can be formed.
Limite inférieure d'inflammabilité LII; lower flammability limit LFL
Concentration of flammable gas, vapor or mist in air, below which an explosive gas atmosphere cannot be formed.
Valeur limite de moyenne d'exposition VME; workplace exposure limit WEL
