Candle-Type Test for Flammability of Polymers

  • C. P. Fenimore


The flammability of a gaseous fuel can be investigated by finding the limiting mixture with air which just propagates a flame. For example,(1) mixtures of hydrogen and air burn only if the molecular ratio, O2/2H2, lies in the range 0.15–10. Mixtures of n-hexane and air burn only over a narrower range of compositions containing 0.3–1.8 times the stoichiometric amount of oxygen. The hydrocarbon may therefore be considered less flammable than hydrogen.
