适用范围：This European Standard describes the general requirements for explosion isolation systems. An explosion isolationsystem is a protective system, which prevents an explosion pressure wave and a flame or only a flame frompropagating via connecting pipes or ducts into other parts of apparatus or plant areas. This European Standardspecifies methods for evaluating the efficacy of the various explosion isolation systems, and methods for evaluatingdesign tools for such explosion isolation systems when applying these in practice.This European Standard also sets out the criteria for alternative test methods and interpretation means to validatethe efficacy of explosion isolations.It covers e.g.:a) general requirements for the explosion isolation components;b) evaluating the effectiveness of an explosion isolation system;c) evaluating design tools for explosion isolation systems.This European Standard is applicable only to the use of explosion isolation systems that are intended for avoidingexplosion propagation between interconnected enclosures, in which an explosion may result as a consequence ofignition of an explosive mixtures e.g., dust-air mixtures, gas-(vapour-)air mixtures, dust-, gas-(vapour-)air mixturesand mists.In general explosion isolation systems are not designed to prevent the transmission of fire or burning powder eitherof which can initiate an explosion in downstream plant items. It is necessary to take this situation into account in riskassessments.This European Standard is only applicable for gas and dust explosions of chemically stable substances and mixturesof these (flame propagating at subsonic velocity).This European Standard is not applicable for explosions of materials listed below, or for mixtures containing some ofthose materials:i) chemically unstable substances that are liable to decompose;ii) explosive substances;iii) pyrotechnic substances.This European Standard does not cover flame arresters. For these devices refer to EN 12874.
