  • optical radiated equipment “Ex op is”
  • Caplights used in mines susceptible to firedamp

The certification is carried out both according toEN harmonized Standards and IEC Standards or prEN Standards.

We also perform the Certification of

  • Explosion Safety Related Equipment
  • Intrinsic Safety Systems of Group I and Group II
  • Electrical accessories of Machines intended for use in potentially explosive atmospheres
  • Dispensers for a liquid and compressed gaseous Fuel
  • Dispensers for a liquid and compressed gaseous Fuel

  1. Electric Safety

The voluntary certification of electrical safety of equipment with the voltage up to 1 000 Volts is carried out in limited scope for:

  • Low voltage electric switchboards with the higher IP degree of protection

  • Household pumping devices

  • Luminaries

  • Electric motors with the higher IP degree of protection

The certification is performed according to EN or IEC harmonised Standards to the LVD Directive. The voluntary certification of electric equipment intended for use in the atmosphere with explosives

  • This certification is carried out in accordance with the Czech national standard ČSN 33 23 40
