Determination of explosion characteristics of dust clouds - Part 2: Determination of the maximum rate of explosion pressure rise (dp/dt)max of dust clouds

This standard describes a test method for the determination of the maximum rate of explosion pressure rise of dust clouds in a closed vessel under defined initial conditions of pressure and temperature.
This method is not suitable for use with recognised explosives, like gunpowder and dynamite, explosives which do not require oxygen for combustion, pyrophoric substances, or substances or mixtures of substances which may under some circumstances behave in a similar manner. Where any doubt exists about the existence of hazard due to explosive properties, expert advice should be sought.

Bestimmung der Explosionskenngrößen von Staub/Luft-Gemischen - Teil 2: Bestimmung des maximalen zeitlichen Druckanstiegs (dp/dt)max von Staub/Luft-Gemischen

Diese Norm legt ein Prüfverfahren fest für die Bestimmung des maximalen zeitlichen Druckanstiegs von
Staubwolken in einem geschlossenen Behälter unter definierten Anfangsbedingungen von Druck und
Temperatur.
Dieses Verfahren ist nicht geeignet für Sprengstoffe, wie Schießpulver und Dynamit sowie Stoffe, die ohne
Sauerstoff verbrennen, pyrophore Stoffe oder Stoffe bzw. Stoffgemische, die sich unter bestimmten
Umständen ähnlich verhalten. Wenn Zweifel über eventuell vorhandene Gefährdungen durch die Explosions-wirkung
bestehen, sollten Fachleute zu Rate gezogen werden.

Détermination des caractéristiques d'explosion des nuages de poussière - Partie 2: Détermination de la vitesse maximale de montée en pression d'explosion (dp/dt)max des nuages de poussière

La présente Norme spécifie une méthode d’essai pour déterminer la vitesse maximale de montée en pression
lors de l’explosion de nuages de poussière dans un récipient fermé, dans des conditions initiales de pression
et de températures définies.
Cette méthode ne convient pas aux explosifs reconnus comme tels, comme la poudre et la dynamite, aux
explosifs dont la combustion ne nécessite pas d’oxygène, aux substances pyrophoriques ou aux substances
et mélanges de substances pouvant, dans certaines circonstances, se comporter de manière similaire.
Lorsqu’il existe un doute sur l’existence d’un phénomène dangereux en raison de propriétés explosives, il
convient de faire appel à l’avis d’experts.
