Method for determination of flammability limits of gaseous compounds diluted with N2 and CO2 in air

At the Fuel Inertization Point (FIP) there is an inert concentration above which the mixture is non-flammable. A method was developed to determine the diluent mole fraction in the combustible-inert mixture at the FIP. The AAREs of 0.82% and 1.95% were obtained for dilution with N2 and CO2, respectively.
