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.
