A general theory is developed which enables closed‐cup flash‐points of mixtures of flammable and non‐flammable liquids to be predicted from a knowledge of certain properties of a flammability diagram. The theory illustrates, quantitatively, the effect of both the flame inhibiting properties of the vapour of the non‐flammable component and the relative volatility of that component. Experimental results for some mixtures of carbon tetrachloride and dichlorodifluoromethane with n ‐hexane, n ‐heptane and n ‐octane are correlated by the theory. The theory also enables a flammability diagram to be partially constructed from standard flashpoint measurements. Such measurements for the n ‐hexane/carbon tetrachloride system are in good agreement with a published flammability diagram.
