[Current]Condensed aerosol fire extinguishing systems - Requirements for system design, installation and commissioning and test methods for components
Specifies requirements for the design, installation, testing, commissioning and safety requirements for condensed aerosol firefighting systems in buildings, plants or other structures. The characteristics of condensed aerosol extinguishing agents and types of fire for which they are a suitable extinguishing medium are also specified. Test methods for components and extinguishing application density and coverage are specified in appendices.
