Scope

ISO 14520-14:2015 contains specific requirements for gaseous fire-extinguishing systems, with respect to the IG-55 extinguishant. It includes details of physical properties, specification, usage and safety aspects.
ISO 14520-14:2015 covers systems operating at nominal pressures of 150 bar at 15 °C, 200 bar at 15 °C, and 300 bar at 15 °C. This does not preclude the use of other systems, although design data for other pressures are not available at this time.
