Notes:
The paper gives an account of recent work at the Safety in Mines Research Establishment (SMRE) aimed at developing a test of high discrimination for examining the deflagration characteristics of permitted explosives that are designed to be very resistent to deflagration. Experience with an existing apparatus in which an explosive contained in a tube is subjected in the presence of coal dust to the detonation products from a charge of the same explosive is reviewed. More recently experiments have been made using an apparatus of the Audibert-Delmas type in which an igniter is used to initiate burning in a primer consisting of explosive mixed with coal dust, and the subsequent burning of the adjoining charge of explosive, which may be surrounded by a sheath of coal dust, is followed by measuring the temperature and pressure of the gases in the containing tube. Various possible test arrangements and criteria for assessing the propensity of an explosive to deflagrate are discussed.
