Gaseous fire-extinguishing systems -- Physical properties and system design -- Part 5: FK-5-1-12 extinguishant
This standard has been revised by ISO 14520-5:2019
ISO 14520-5:2016 contains specific requirements for gaseous fire-extinguishing systems, with respect to FK-5-1-12 extinguishant. It includes details of physical properties, specification, usage and safety aspects.
ISO 14520-5:2016 covers only systems operating at nominal pressures of 25 bar, 34,5 bar, 42 bar and 50 bar with nitrogen propellant. This does not preclude the use of other systems.
