ATEX Markings - Definitions

  • Symbol for protection against explosion according to ATEX standards.
  • Tools of class I may be used in mines with explosive atmospheres and occurence of combustible dust.
  • Devices of group II are permissible for use in environments outside mining.
  • Category 1 means adaption to zone 0 of explosiveness. These are locations where explosive atmospheres will always be present. This is the interior of tank farms.
  • Category 2 means adaption to zone 1 of explosiveness. These are locations where explosive atmospheres can occur regularly; this means 10-1000 h per year. These are e.g. filling stations, environments of tanker or working pits for motorcars.
  • With permission for gases and vapours.
  • Approved for dust.
  • Category M1: Devices of this category are for use in underground mines and overground areas, where explosive methan-gas and dust can apear.
  • Category 2 corresponds to zone 21 These are areas in which ever-explosive atmosphere in the form of a cloud of combustible dust in the air for long periods or frequently.
  • Identification of the type of protection for explosion protection
  • With permission for use in surroundings with explosive atmosphere. marking after AtEx-rules: permission for use in environment with danger of explosives.
  • Class of protection. ia = intrinsically safe. The circuits of the lamp will not produce any sparks that can ignite an explosive atmosphere. This is even true if two rare failures occur simultaneously.
  • Class of protection. ib = intrinsically safe. The circuits of the lamp will neither in regular function nor in case of failure produce any sparks that can ignite an explosive atmosphere.
  • The lamp has permission for explosive class IIB and may be used, when gases of this class are present, e.g. vapours of fuel.
  • The lamp has permission for explosives class IIC and may be used, when gases of this class are present, e.g. hydrogen, vapours of fuel or acetylene.
  • Also accepted for use in atmospheres with hydrogen (gas of group IIC)
  • The lamp has permission for temperature class T4. It may not be used when gases are present that will ignite below 135 °C.
