适用范围：This European Standard specifies the basic design requirements for the selection of a gas explosion ventingprotective system. This European Standard, EN 14797 and EN 14460 form a series of three standards whichare used together.NOTE 1 These three standards together represent the concept of gas explosion venting.NOTE 2 To avoid transfer of explosions to other communicating equipment one should also consider applyingprEN 15089.This European Standard is applicable to: 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 European Standard does not provide design and application rules against effects generated bydetonation reactions or runaway exothermic reactions including decomposition in the gas phase.This European Standard is not applicable to: fire risks arising either from materials processed, used or released by the equipment or from materialsthat make up equipment and buildings; design, construction and testing of explosion venting devices, which are used to achieve explosionventing1); protection against overpressures caused by events such as overfilling, overpressurisation, fire engulfment,overheating etc.NOTE 3 Protection by venting against dust and hybrid explosions is specified in EN 14491.
