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 prEN 14797 Explosion venting devices
and prEN 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 prEN 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.
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 either materials processed, used or released by the equipment or 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 venting1).
