scope:

This European Standard specifies the basic requirements ofdesign for the selection of a dust explosion venting protectivesystem. This European Standard is one of a series including EN14797, Explosion venting devices and EN 14460, Explosion resistantequipment. The three standards together represent the concept ofdust explosion venting. To avoid transfer of explosions to othercommunicating equipment, one should also consider applying EN 15089Explosion Isolation Systems. This European Standard covers: - ventsizing to protect an enclosure against the internal pressureeffects of a dust explosion; - flame and pressure effects outsidethe enclosure; - recoil forces; - influence of vent ducts; - hybridmixtures.
