AS 4214:2018 PDF
The objective of this Standard is to provide designers and installers with minimum requirements for the design, installation, testing and commissioning of gaseous fire extinguishing systems for structures, building and plant.
This Standard specifies requirements and gives recommendations for the design, installation, testing, maintenance and safety of gaseous fire-extinguishing systems and the characteristics of the various extinguishing agents and types of fire for which they are a suitable extinguishing medium.
It covers total flooding systems utilizing electrically non-conducting gaseous fire extinguishing agents that do not leave a residue after discharge and for which there is sufficient data currently available to enable validation of performance and safety characteristics by an appropriate independent authority.
Explosion suppression or oxygen reduction fire prevention systems are not within the scope of this Standard.
This Standard is not intended to indicate approval of the extinguishing agents listed therein by the appropriate authorities, as other extinguishing agents may be equally acceptable.
With the exception of marine CO2 fire extinguishing systems, specified in Appendix A, CO2 systems are not covered by this Standard as they are covered by AS 6183. This Standard is applicable to the extinguishing agents listed in Table 1. The physical properties and characteristics of each extinguishing agent are detailed in the relevant appendix of this Standard.
