Determination of explosion characteristics of dust clouds - Part 1: Determination of the maximum explosion pressure pmax of dust clouds

This document describes a test method for the determination of the maximum explosion pressure 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, substances 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 1: Bestimmung des maximalen Explosionsdruckes pmax von Staub/Luft-Gemischen

Dieses Dokument legt ein Prüfverfahren für die Bestimmung des maximalen Explosionsdruckes von Staubwolken in einem geschlossenen Behälter unter definierten Anfangsbedingungen von Druck und Temperatur fest. 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 1: Détermination de la pression maximale d'explosion pmax des nuages de poussière

La présente norme décrit une méthode d'essai permettant de déterminer la pression maximale d'explosion des
nuages de poussière dans un récipient fermé, dans des conditions initiales définies de pression et de température.
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 ou 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.

Ugotavljanje eksplozijskih značilnosti oblakov prahu - 1. del: Ugotavljanje najvišjega tlaka eksplozije pmax oblakov prahu

Ta dokument opisuje preskusno metodo za ugotavljanje najvišjega tlaka eksplozije oblakov prahu v zaprti posodi pod opredeljenimi začetnimi pogoji glede tlaka in temperature.
Ta metoda ni primerna za uporabo s priznanimi eksplozivi, kot so smodnik in dinamit, snovi, ki za izgorevanje ne potrebujejo kisika, piroforne snovi ali snovi ali zmesi snovi, ki se lahko v nekaterih okoliščinah podobno obnašajo. Kadar obstaja kakršen koli dvom o nevarnosti zaradi eksplozivnih lastnosti, je treba poiskati strokovni nasvet.
