Gun Propellant Behavior Mastering During Handling and Manufacturing
Abstract
According to UN recommendations or national regulations, gun propellants may be classified in 1.3 or 1.1 hazard division. Handling and manufacturing small caliber gun propellants were identified to lead to mass explosion in different countries. Nevertheless, it was possible to guarantee a 1.3 classification for small caliber gun propellant in container when restricting the loading height. Our recent full scale works have confirmed that even large caliber gun propellants are able to give also explosion mass or pneumatic explosion hazard depending on the confinement (self confinement or container confinement). The methodology used by SNPE to guarantee a 1.3 classification for all kinds of gun propellants is presented in this paper. This methodology is first based on correlation between laboratory tests and small scale tests. It is secondly reinforced by TDD simulations. According to UN recommendations, gun propellants may be classified 1.3 or 1.1. In fact, 1.1 hazard classification for hunting powders and small caliber gun propellants is well known and identified. But also when gun propellants are contained in metallic container, pneumatic explosion must be evaluated. Practically, everybody knows that projection hazard and explosion mass hazard are mastered in restricting the loading height of gun propellants in a given container.
