A new approach to the classification of high energy propellants and explosives according to their susceptibility to undergo transition to detonation shows promising results. The method involves the burning of large solid cylinders of the material under consideration in a closed bomb at high pressure. At a pressure which is characteristic for each composition and condition, the burning rate vs. pressure curve obtained shows a marked deviation from the results predicted from strand burning tests. This deviation is indicative of a pre-detonation reaction which takes place in the explosive and which could proceed into detonation if sufficient material were available. Two secondary explosives and a number of rocket propellants were tested.
