Résumé

ASHRAE and also ISO and Japanese high-pressure gas safety legal requirements classifying the flammability of refrigerants are evaluated to show why these methods conflict with the test results. The key finding of this paper is that the ratio of stoichiometric concentration to LFL concentration (R factor) represents the test results most precisely. In addition, it shows excellent correlation with other flammability parameters such as flame speed and pressure rise coefficient. Classification according to this index gives reasonable flammability order of substances including ammonia, R152a and carbon monoxide. Theoretical background explaining why this index gives good correlation is discussed, as are the limitations of this method.
