DIN EN 14994:2007 PDF

Scope: This European Standard specifies the basic design requirements for the selection of a gas explosion venting protective system.This European Standard,EN 14797 and EN14460 form a series of three standards which are used together. NOTE 1 These three standards together repressent the concept the concept pf gas explosion venting. NOTE 2 To avoid transfer of explosions to other communicating equipment one should also consider applying prEN 15089. This European Standard is applicable to: - vent sizing to protect against the internsl pressure effects of a gas explosion; - flame and pressure effects outside the enclosure; - recoil forces; - influence of vent ducts; - influence of initialtemperature and pressure. This European Standard does not provide design and application rules against effects generated by detonation reactions or runaway exothermic reactions including decomposition in the gas phase. This European Standard is not applicable to: - fire risks arising either from materials processed,used or released by the equipment or frommaterials that make up equipment and buildings; - design,construction and testing of explosion venting devices,which are used to achieve explosion venting﹤up 1﹚﹥; - protection against overpressures caused bu events such as overfilling,overpressurisation,fire engulfment,overheatingetc. NOTE 3 Protection by venting against dust and hybrid explosions is specified in EN 14491.
