|Status:||Draft for Comment|
This standard 21/30423898 DC BS EN 13938-3. Explosives for civil uses. Propellants and rocket propellants is classified in these ICS categories:
- 71.100.30 Explosives. Pyrotechnics and fireworks
This document specifies a method to determine the tendency of a propellant to undergo transition from deflagration to detonation (DDT). It applies to propellants of a grain size up to 8 mm. This method does not apply to black powder and rocket propellant.
Due to the nature of the shape of grains (heterogeneous), the combustion of the rocket propellant can cause a crack of the grain causing an explosion of the rocket motor.
Black powders properties differ significantly from propellant and explosives because black powders are capable of maintaining stable combustion at high velocities without experiencing deflagration – detonation transition.
