This part of ISO 14520 gives specific requirements for gaseous fire-extinguishing systems, with respect to the HFC 125 extinguishant. It includes details of physical properties, specification, usage and safety aspects and is applicable to systems operating at nominal pressures of 25 barand 42 bar, superpressurized with nitrogen. This does not preclude the use of other systems.
