Alcance
This document contains specific requirements for gaseous fire-extinguishing systems, with respect to FK-5-1-12 extinguishant. It includes details of physical properties, specifications, usage and safety aspects.This document is applicable only to systems operating at nominal pressures of 25 bar, 34,5 bar, 42 bar and 50 bar[1] with nitrogen propellant. This does not preclude the use of other systems.[1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.
