Explosives for civil uses - Propellants and rocket propellants - Part 4: Determination of burning rate under ambient conditions

This document specifies a method for the determination of burning rate under ambient conditions for solid gun propellants. It is applicable to solid gun propellants and black powder in their original form up to a grain size of 8 mm.
NOTE 1   Knowledge of burning rate is of high importance to manage risks associated with handling such explosives and of high importance to assess whether performance characteristics are met.
NOTE 2   In cases where propellants having grain size higher than 8 mm are generally used, their burning rate is more influenced and controlled by parameters of element containing thereof, and thus knowledge of their burning rate at ambient condition is not of high importance.

Explosivstoffe für zivile Zwecke - Treibladungspulver und Raketentreibstoffe - Teil 4: Bestimmung der Brenngeschwindigkeit bei Umgebungsbedingungen

Dieses Dokument legt ein Verfahren für die Bestimmung der Brenngeschwindigkeit von Schießpulver bei Umgebungsbedingungen fest. Es ist für Schießpulver und für Schwarzpulver in deren ursprünglichen Form bis zu einer Korngröße von 8 mm anwendbar.
ANMERKUNG 1   Die Kenntnis über die Brenngeschwindigkeit ist von großer Bedeutung, um mit den Risiken in Zusammenhang mit der Handhabung solcher Explosivstoffe umzugehen, und um zu beurteilen, ob die Leistungsmerkmale erfüllt sind.
ANMERKUNG 2   In Fällen, in denen die Verwendung von Treibladungspulver mit einer Korngröße über 8 mm üblich ist, wird ihre Brenngeschwindigkeit stärker von den Parametern des Elements, das sie enthält, beeinflusst und gesteuert, und daher ist die Kenntnis ihrer Brenngeschwindigkeit bei Umgebungsbedingungen nicht von großer Bedeutung.

Explosifs à usage civil - Poudres propulsives et propergols pour fusées - Partie 4 : Détermination de la vitesse de combustion dans les conditions ambiantes

Le présent document spécifie une méthode de détermination de la vitesse de combustion dans les conditions ambiantes pour les poudres pour armes. Il est applicable aux poudres pour armes et aux poudres noires dans leur forme d'origine, jusqu'à une granulométrie de 8 mm
NOTE 1   La connaissance de la vitesse de combustion est de la plus haute importance pour gérer les risques associés à la manipulation de ces explosifs et pour vérifier si les caractéristiques de performance sont respectées.
NOTE 2   Dans les cas où les poudres propulsives ayant une granulométrie supérieure à 8 mm sont couramment utilisées, leur vitesse de combustion est davantage influencée et contrôlée par les paramètres de l'élément qui les contient, et donc la connaissance de la vitesse de combustion dans les conditions ambiantes n'est pas d'une grande importance.
