New revised VDI guideline 3673 “Pressure release of dust explosions”



The VDI Guideline 3673 “Pressure Release of Dust Explosions” published in June 1979 [1] describes one of the possible constructional protective measures against the effect of dust explosions and provides details on the venting area requirements of vessels and silos. Thanks to the results of extensive explosion trials conducted in the last ten years on the problems addressed above, important gaps in our knowledge have been filled and new findings gained which have made a revision of the above guidline necessary. The contents of the new version are reported and attention drawn to modifications compared with the first version.
