This part of ISO 14520 gives specific requirements for gaseous fire-extinguishing systems, with respect to the
FK-5-1-12 extinguishant. It includes details of physical properties, specification, usage and safety aspects and
is applicable to systems operating at nominal pressures of 25 bar and 42 bar with nitrogen propellant. This does
not preclude the use of other systems.
