Dust explosion venting protective systems

Status : Current, Under review   Published : August 2012
Conformity to regulation : Designated



This European Standard specifies the basic requirements of design for the selection of a dust explosion venting protective system. The standard is one of a series including EN 14797, Explosion venting devices and EN 14460, Explosion resistant equipment. The three standards together represent the concept of dust explosion venting. To avoid transfer of explosions to other communicating equipment, one should also consider applying EN 15089 Explosion Isolation Systems. This European Standard covers: - vent sizing to protect an enclosure against the internal pressure effects of a dust explosion; - flame and pressure effects outside the enclosure; - recoil forces; - influence of vent ducts; - hybrid mixtures. This European Standard is not intended to provide design and application rules against effects generated by detonation reactions or runaway exothermic reactions. This European Standard does not cover fire risks arising from materials either processed, used or released by the equipment or from materials that make up equipment and buildings. This European Standard does not cover the design, construction, testing and certification of explosion venting devices that are used to achieve explosion venting
