Testing

Test laboratories are able to perform all tests, necessary for purpose of certification according to the Standards, harmonized to the 94/9/EC Directive. The subcontracting is used in the exceptional circumstances and case by case only, and with the keeping of ISO IEC EN 17025 principles.

There are above all:

  • Tests of electrical and non-electrical equipment for explosive atmospheres
  • Tests of protective systems for a suppression, decoupling and relieve of explosion
  • Thermal tests of equipment by the contact method and non-contact IR method under the required operation conditions
  • The measurement explosion pressures of gas and dust mixture inside of equipment and during the test of protective systems or under increased initial pressure respectively
  • Electric tests and measurement of voltage, currents, electric power, leakage currents, electric resistance, dielectric strength
  • Performance tests of gas detectors and analyzers
  • Tests of surface and internal resistance and charging tests of plastic materials
  • Measurement of very high and very low electric resistance
  • Burning tests
  • Test under the abnormal climatic conditions (temperature and humidity), environmental tests
  • Measurement of mechanical dimensions of flameproof gaps
  • Electromagnetic emissivity tests
  • Electromagnetic immunity tests

Special tests:

  • Bonfire test of gas cylinders
  • Bonfire test of automotive LPG and CNG containers
  • Test of valves for explosion relief in the engine crank case
  • Records of fast moving events by high speed camera
  • Estimation of dust concentration in the ventilation and exhaust systems
  • Other Tests on customer’s request, based on the laboratories abilities.
