Identification of Equipment

Equipment intended for use in hazardous areas must be uniquely identified by the manufacturer. To comply with EN 50014 or EN 60079-0 / EN 50020 or EN 60079-11 the equipment must be labeled with the following information:

  • Manufacturer name and address
  • CE mark
  • Designation of the series and type
  • Serial number, if applicable
  • Year of manufacture
  • Special identification for the prevention of explosions in conjunction with the identification of the category

For the equipment group II the letter “G” (for areas in which potentially explosive gas, vapor, mist and air mixtures are present) and/or the letter “D” (for areas where dust may form potentially explosive atmospheres).
