Meaning of the ATEX marking:

This product is thus designed to be used in an above-ground industrial environment, in zone 1 with group IIB gas (e.g. ethylene) present. The product's surface temperature will not exceed 85° C: thus care must be taken to not use this product in the presence of gas having an ignition temperature of less than 85° C

ATEX marking detail for PIXA 1, 2 and 3 headlamps:

These 3 lamps have the same ATEX marking:

Ex II 3 GD

Ex nA ic IIB T4 Gc

Ex tc IIIC T135° C Dc

• General marking Ex II 3 GD
  
  II: above-ground industry.
  
  3 GD: category of 3GD lamps that determines the zone of use, in this case zone 2/22 (gas/dust)

• ATEX zone 2 protection: gas-specific marking: Ex nA ic IIB T4 Gc
  
  nA: protection mode against risk of sparking
  
  ic: intrinsically safe protection mode
  
  IIB : lamp designed for an environment presenting a type of gas belonging to the IIB gas group
  
  T4: maximum surface temperature of the lamp: 135° C
  
  Gc: normal protection level

• ATEX zone 22 protection: dust-specific marking: Ex tc IIIC T135° C Dc
  
  tc: enclosure protection mode
  
  IIIC: lamp designed for an environment presenting a dust type belonging to dust group IIIC
  
  T135°C: maximum lamp temperature: 135° C
  
  Dc: normal protection level

(1) Examples of protection modes:

tD: protection by enclosure for electrical equipment for dust hazard

mD: encapsulation for electrical equipment for dust hazard

iD: intrinsic safety for electrical equipment for dust hazard

n: non-incendive for electrical equipment for gas hazard

nA: non-sparking (zone 2 or Gc)

nR: restricted breathing (zone 2 or Gc)

nL: energy limitation (zone 2 or Gc)

nC: sealed device (zone 2 or Gc)

ma/mb: encapsulation for electrical equipment for gas hazard

c: protection by construction for non-electric equipment, e.g. mechanical

ic: intrinsic safety for electrical equipment for gas hazard (zone 2 or Gc)
