Determination of explosion limits of gases and vapours

This standard specifies a test method to determine the explosion limits of gases, completely evaporated liquids (vapours) and their mixtures mixed with air. An air/inert gas mixture (volume fraction of the oxygen <21%) can be used as oxidizer in the place of air. This standard applies to gases, vapours and their mixtures at atmospheric pressure and at temperatures from ambient temperature to 200 °C.

Bestimmung der Explosionsgrenzen von Gasen und Dämpfen

Diese Europäische Norm legt zwei Verfahren (Methode T und Methode B) zum Bestimmen der Explosionsgrenzen von Gasen, Dämpfen und deren Gemischen in Mischung mit Luft fest. An Stelle von Luft kann als Oxidator auch ein Luft/Inertgas-Gemisch (Volumenanteil des Sauerstoffs < 21 %) verwendet werden. In dieser Europäischen Norm subsumiert der Ausdruck �Luft" auch solche Luft/Inertgas-Gemische.
Dieses Verfahren gilt für Gase, Dämpfe und deren Gemische bei Umgebungsdruck und Temperaturen von Raumtemperatur bis 200 °C.

Determination des limites d'explosivité des gaz et des vapeurs

La présente Norme européenne spécifie deux méthodes d'essai (méthode T et méthode B) pour déterminer les limites d'explosivité dans l'air des gaz, des vapeurs et de leurs mélanges. Un mélange d'air et d'un gaz inerte (fraction volumique de l'oxygène inférieure à 21 %) peut être utilisé comme comburant, au lieu de l'air. Dans cette norme, le terme " air " comprend également les mélanges air/gaz inerte.
La présente norme s'applique aux gaz, aux vapeurs et à leurs mélanges à la pression atmosphérique et à des températures comprises entre la température ambiante et 200 °C.

This European Standard was approved by CEN on 7 August 2003.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official
versions.
