24/30492512 DC

This standard 24/30492512 DC BS EN 15089 Explosion isolation systems is classified in these ICS categories:

• 13.230 Explosion protection
• 13.230 Explosion protection

This document specifies the general requirements for explosion isolation systems. An explosion isolation system is an autonomous protective system which aims to prevent an explosion pressure wave and a flame or only a flame from propagating via connecting pipes or ducts into other parts of apparatus or plant areas. This document also specifies methods for evaluating the efficacy of the various explosion isolation systems, and methods for evaluating design tools for such explosion isolation systems when applying these in practice. This document also sets out the criteria for alternative test methods and interpretation means to validate the efficacy of explosion isolation systems. This document does not cover flame arresters, diverters, and explosion isolation flap valves. For these devices refer to EN ISO 16852:2016 , EN 16020:2011, and EN 16447:2014 respectively. This standard covers e.g.: a) general requirements for the explosion isolation components; b) evaluating the efficacy of an explosion isolation system; c) evaluating design tools for explosion isolation systems. This document is applicable only to the use of explosion isolation systems that are intended for avoiding explosion propagation between interconnected enclosures, in which an explosion can result as a consequence of ignition of explosive mixtures, e.g. dust-air mixtures, gas-(vapour-)air mixtures, dust-, gas-(vapour-)air mixtures and mists. It is not applicable to detonation events.
