In the course of testing a new storage concept for granular propellants, the transition deflagration‐detonation has been investigated on a porous nitrocellulose propellant, on a nitroglycerin flake propellant and on a single‐perforated nitrocellulose propellant without surface treatment. Test charges weighed from 1 kg to 770 kg and the temperatures ranged from 10°C to 71°C. The test containers consisted of steel, of wood or of a combination of both steel and wood. Temperature coefficients have been established in the order of −0.6%/°C for the critical height of bed for detonation.
