EN 12094-8:2006 (E) 5 Introduction It has been assumed in the preparation of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. All pressure data in this European Standard are given as gauge pressures i

30、n bar, unless otherwise stated. NOTE 1 bar = 105N m-2= 100 kPa. EN 12094-8:2006 (E) 6 1 Scope This European Standard specifies requirements and describes test methods for flexible and rigid connectors used in CO2-, Inert Gas- or Halocarbon gas fire extinguishing systems. This European Standard is ap

31、plicable to connectors used: between container valves and the manifold (type 1 and type 5 connector); in pneumatic pilot lines (type 3 connector); in distribution pipework of fire extinguishing installations downstream of the manifold/selector valve (type 2 or type 4 connector). 2 Normative referenc

32、es The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies.
