DIN EN 14797:2007-03

This EN specifies the requirements for venting devices used to protect enclosures against the major effect of internal explosions arising from the rapid burning of suspended dust, vapour or gas contained within. It includes the requirements for the design, inspection, testing, marking, documentation and packaging. The standard specifies explosion venting devices which are put on the market as autonomous protective systems. The application and specification of explosion venting devices is outlined for dust explosion protection in EN 14491 and for gas explosion protection in prEN 14994. The standard does not cover details for the avoidance of ignition sources from detection devices or other parts of the venting devices.
