NBN EN 1839:2003

This standard specifies a test method to determine the explosion limits of gases, completely evaporated liquids (vapours) and their mixtures mixed with air. An air/inert gas mixture (volume fraction of the oxygen <21%) can be used as oxidizer in the place of air. This standard applies to gases, vapours and their mixtures at atmospheric pressure and at temperatures from ambient temperature to 200 °C.
