Determination of the maximum explosion pressure and the maximum rate of pressure rise of gases and vapours - Part 1: Determination of the maximum explosion pressure
The standard test method is designed to determine the explosion pressure and the maximum explosion pressure of a flammable gas/air/inert mixture at ambient temperature and pressure. In this standard, "gas" also includes vapours but not mists. Detonation phenomena are not considered in this standard.
Verfahren zur Bestimmung des maximalen Explosionsdruckes und des maximalen zeitlichen Druckanstieges für Gase und Dämpfe - Teil 1: Bestimmungsverfahren für den maximalen Explosionsdruck
Diese Norm legt ein Verfahren fest für das Bestimmen des Explosionsdruckes und des maximalen Explosionsdruckes ruhender Gemische aus brennbaren Gasen (Brennstoff), Luft und Inertgas bei Umgebungsbedingungen in geschlossenen Behältern ohne Einbauten. In dieser Europäischen Norm subsummiert der Ausdruck "Gas" auch Dämpfe, jedoch nicht Nebel.
Diese Europäische Norm gilt nicht für Gemische, die einen erhöhten Sauerstoffanteil aufweisen und für Gemische, die bei Umgebungsbedingungen spontan reagieren. Diese Europäische Norm gilt nicht für Bedingungen, unter denen Detonations- und Zersetzungsphänomene auftreten können.
Die nach dem hier beschriebenen Normverfahren bestimmten Drücke sind nicht anwendbar für die Auslegung druckfester Kapselung oder anderer geschlossener Behälter, deren innere Geometrie zu überdurchschnittlich hohen Explosionsdrücken aufgrund von Vorkompression führen kann. Druckfeste Kapselung ist eine Umschließung, die im Innern stattfindenden Explosionen standhält und deren Übertragung in äußere explosionsfähige Atmosphären verhindert. Selbst in Umschließungen relativ einfacher Geometrie können Einbauten zu deutlich höheren Explosionsdrücken als nach dieser Europäischen Norm bestimmt führen. Druckfeste Kapselung sollte für elektrische Betriebsmittel nach den Anforderungen in EN 50018 und für nicht elektrische Betriebsmittel nach den Anforderungen in prEN 13463-3 ausgelegt und geprüft werden.
Détermination de la pression maximale d'explosion et de la vitesse maximale de montée en pression des gaz et vapeurs - Partie 1: Détermination de la pression maximale d'explosion
La présente méthode d'essai normalisée est conçue pour déterminer la pression d'explosion et la pression maximale d'explosion d'un mélange gaz combustible/air/gaz inerte, contenu au repos dans un récipient fermé vide d'obstacles, à température et pression ambiantes. Dans la présente Norme européenne, le terme « gaz » inclut les vapeurs mais n'inclut pas les brouillards.
La présente Norme européenne ne s'applique pas aux mélanges contenant de l'air enrichi en oxygène ; ou des mélanges réagissant spontanément à la température ambiante et à la pression. Les phénomènes de détonation et de décomposition explosive ne sont pas pris en compte dans la présente Norme européenne.
Les pressions mesurées selon les modes opératoires définis dans la présente Norme européenne ne s'appliquent pas aux enveloppes antidéflagrantes, c'est-à-dire aux enveloppes destinées à résister à une explosion interne et à ne pas la transmettre à une atmosphère explosive externe, ou à tout autre volume fermé où la géométrie interne peut induire un accroissement de la pression. Même dans une enveloppe de géométrie relativement simple, la disposition des équipements internes peut conduire à des pressions d'explosion significativement supérieures à celles mesurées selon la présente Norme européenne. Les enveloppes antidéflagrantes doivent être construites et soumises à essai conformément aux exigences des normes EN 50018 pour les appareils électriques et prEN 13463-3 pour les appareils non-électriques.

Evenin an enclosure of relatively simple geometry the disposition of the internal components can lead to explosionpressures significantly higher than those measured using this European Standard.
Flameproof enclosures shouldbe constructed and tested in accordance with the requirements contained in EN 50018 for electrical equipment andprEN 13463-3 for non-electrical equipment.2 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply.2.1explosion pressure, Pexhighest pressure occurring in a closed vessel during the explosion of a specific mixture of flammable gases with airor air and inert gases determined under specified test conditions2.2maximum explosion pressure, Pmaxmaximum value measured in the tests for explosion pressure when the content of the flammable gas in the mixtureis variedNOTEFor the purpose of this European Standard, all pressures are expressed in bar absolute.3 Test method3.1 PrincipleAn explosive test mixture is ignited by a defined ignition source which is positioned in the centre of a test vessel. Bymeans of a pressure measuring system, the highest pressure Pex developed following the ignition of the testmixture is measured.The maximum explosion pressure Pmax is determined during measurements of the explosion pressure Pex byvarying stepwise the content of flammable gas in the mixture, until the maximum value of Pex is found.3.2 Apparatus3.2.1 GeneralThe test apparatus consists of :¾ a test vessel;¾ equipment for preparing the test mixture;¾ an ignition system;¾ a pressure measuring system;SIST EN 13673-1:2003
