Part 1: General requirements . 
6. Description of content:  This part of ISO 14520 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 exp losion suppression.  
This part of ISO 14520 is not intended to indicate approval of the extinguishants listed 
therein by the appropriate authorities, as other extinguishants may be equally acceptable.
