This standard specifies the constructional requirements for ventilating fans constructed to Group II G categories 1, 2 and 3 , and Group II D categories 2 and 3, intended for use in explosive atmospheres. Operation conditions for the different categories of fans used in this standard are defined in clause 4. It does not apply to fans intended for use with Group II C gases, as listed in the annex to EN 50014 This Standard does not apply to group I fans (fans for mining), cooling fans or impellers on rotating electrical machines, cooling fans or impellers on internal combustion engines. The standard specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres may exist inside, outside, or inside and outside of the fan. This standard is valid for fans working in ambient atmospheres having absolute pressures ranging from 0,8 bar to 1,1 bar, temperatures ranging from - 20 °C to + 60 °C, maximum 21 vol. % oxygen content and an aerodynamic energy increase of less than 25 kJ/kg.
