Flammability of Gases Test Apparatus

The DEKRA Flammability of Gases test apparatus is designed for conducting physical properties testing to the European Official Journal of Tests – Test A11. This method determines whether gases mixed with air at room temperature (approx 20 °C) and atmospheric pressure, are flammable and if so, over what range of concentrations.

Mixtures of increasing concentrations (1% steps) of the test gas with air are exposed to an electrical spark and it is observed whether ignition occurs.

Functional Specification & Deliverables

  • 1 x 15 kV constant arc power source
  • 1 x gas flow meter base plate with ignition and timer control
  • 1 x pair non return valve and pre-mixing chamber and isolation valve pre-fitted to gas flow meter base plate
  • 2 x gas mass flow meters (gas flow meter digital pre-programmed gases)
  • 1 x power adapter unit for gas flow meters
  • 1 x set glass tube sealing membrane
  • 1 x flexible gas tube
  • 1x glass test tube (quick tube bayonet release mechanism fitted)
  • 1 x instruction manual

Optional Extras

  • Spare glass tubes
  • Calibration services
