(Main)Determination of explosion limits of gases and vapours
Determination of explosion limits of gases and vapours
This European Standard specifies two test methods (method T and method B) to determine the explosion limits of gases, vapours and their mixtures, mixed with air. An air/inert gas mixture (volume fraction of the oxygen < 21 %) can be used as the oxidizer instead of air. In this European Standard, the term "air" includes such air/inert mixtures.
This European Standard applies to gases, vapours and their mixtures at atmospheric pressure for temperatures up to 200 °C.
Bestimmung der Explosionsgrenzen von Gasen und Dämpfen
Diese Europäische Norm legt zwei Prüfverfahren (Verfahren T und Verfahren B) zum Bestimmen der Explosions¬grenzen 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 Norm subsumiert der Ausdruck „Luft“ auch derartige Luft/Inertgas-Gemische.
Dieses Dokument gilt für Gase, Dämpfe und deren Gemische bei Umgebungsdruck und Temperaturen von Raumtemperatur bis 200 °C.
Détermination des limites d'exposivité des gaz et vapeurs
La présente Norme européenne spécifie deux méthodes d’essai (la méthode T et la méthode B) pour déterminer les limites d’explosivité de gaz, de vapeurs et de mélanges de gaz et de vapeurs mélangé à l’air. Un mélange d’air et de gaz inerte (fraction volumique de l’oxygène < 21 %) peut servir d’oxydant à la place de l’air. Dans la présente Norme européenne, le terme « air » inclut ces mélanges d’air et de gaz inerte.
La présente Norme européenne s’applique aux gaz, aux vapeurs et à leurs mélanges à la pression atmosphérique pour des températures jusqu’à 200 °C.
Ugotavljanje mej eksplozivnosti plinov in hlapov
Ta evropski standard določa dve preskusni metodi (metodo T in metodo B) za ugotavljanje mej eksplozivnosti plinov, hlapov in njihovih mešanic, zmešanih z zrakom. Namesto zraka je kot oksidant mogoče uporabiti mešanico zraka in inertnega plina (delež prostornine kisika < 21 %). Izraz »zrak« v tem evropskem standardu vključuje take mešanice zraka/inertnega plina. Ta evropski standard se uporablja za pline, hlape in njihove mešanice pri atmosferskem tlaku pri temperaturah do 200 °C.

This European Standard was approved by CEN on 27 July 2012.
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 CEN-CENELEC 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 CEN-CENELEC Management Centre has the same
status as the official versions.
