This European Standard describes the basic requirements of gas explosion venting protective systems. It covers: - vent sizing to protect against the internal pressure effects of a gas explosion - flame and pressure effects outside the enclosure - recoil forces - influence of vent ducts - influence of initial temperature and pressure. This standard is not intended to provide design and application rules against effects generated by detonation reactions or runaway exothermic reactions including decomposition in the gas phase. This standard does not cover fire risks arising either from materials processed, used or released by the equipment or from materials that make up equipment and buildings. This standard does not cover the design, construction and testing of explosion venting devices, which are used to achieve explosion venting1). This standard does not cover protection against overpressures caused by events such as overfilling, overpressurisation, fire engulfment, overheating, etc. Protection by venting against dust and hybrid explosions is described in the standard "Dust explosion venting protective systems2)"
