Flammability limits of combustible gases and vapors measured by a tubular flame method

A tubular flame burner method was employed as a new test method for flammability limits, and repeatable and reliable flammability limits were measured. The data were obtained under well-defined conditions. New data on the flammable regions of mixtures of several hydrocarbons and ethanol with inert gases and halogenated fire suppressants in air are reported and compared with the literature data.
