This document specifies minimum requirements and defines the specifications governing the design, installation and maintenance of fixed oxygen reduction systems with oxygen reduced air for fire prevention in buildings and industrial production plants. It also applies to the extension and modification of existing systems. This document applies to oxygen reduction systems using nitrogen-enriched-air which are designed for continual oxygen reduction in enclosed spaces. NOTE Nitrogen is, today, the most suitable gas to be used for oxygen reduction. For other gases, this document can be used as a reference. This document does not apply to: — oxygen reduction systems that use water mist or combustion gases; — explosion suppression systems; — explosion prevention systems, in case of chemicals or materials containing their own supply of oxygen, such as cellulose nitrate; — fire extinguishing systems using gaseous extinguishing agents; — inertization of portable containers; — systems in which oxygen levels are reduced for reasons other than fire prevention (e.g. steel processing in the presence of inert gas to avoid the formation of oxide film); — inerting required during repair work on systems or equipment (e.g. welding) in order to eliminate the risk of fire or explosion. In addition to the conditions for the actual oxygen reduction system and its individual components, this document also covers certain structural specifications for the protected area. The space protected by an oxygen reduction system is a controlled and continuously monitored indoor climate for extended occupation. This document does not cover unventilated confined spaces that can contain hazardous gases.

ISO 14520-1:2015 specifies requirements and gives recommendations for the design, installation, testing, maintenance and safety of gaseous fire fighting systems in buildings, plants or other structures, and the characteristics of the various extinguishants and types of fire for which they are a suitable extinguishing medium. It covers total flooding systems primarily related to buildings, plants and other specific applications, utilizing electrically non-conducting gaseous fire extinguishants that do not leave a residue after discharge and for which there are sufficient data currently available to enable validation of performance and safety characteristics by an appropriate independent authority. This part of ISO 14520 is not applicable to explosion suppression. ISO 14520-1:2015 is not intended to indicate approval of the extinguishants listed therein by the appropriate authorities, as other extinguishants may be equally acceptable. CO2 is not included as it is covered by other International Standards.

ISO 16003:2008 specifies requirements and describes test methods for the following components used in gaseous fire-extinguishing systems: container valve assemblies, which include container valve, actuator and, if applicable, a diptube; selector valves and their actuators; agent distribution nozzles; flexible connectors; and check and non-return valves. Container valve assemblies are designed to control the extinguishant flow from the container to the distribution pipe work. They are normally in the closed position. The automatic control device triggers the actuator and the valve opens. Where applicable, the requirements contained in the test methods also apply to separate container valves. The design of the nozzles influences the area coverage, the height limitations, the discharge rate and the flow rate. ISO 16003:2008 is applicable to check valves installed between container valve and manifold and non-return valves installed in pilot lines, except those valves that are tested in combination with non-electrical control devices. It is required that non-return and check valves allow the passage in the direction of flow and prevent flow in the reverse direction.
