This European Standard specifies requirements and gives recommendations for the design, construction and maintenance of kits covering components of powder fire extinguishing systems which discharge powder from a container, or centrally grouped containers, through nozzles by means of expellant gas in accordance with EN 12416-1:2001 and the relevant part of EN 54 where required.This European standard covers systems which are suitable for general use in buildings and other construction works as well as outdoor hazards. This standard does not cover stored pressure systems or pre-engineered systems up to 150 kg of the extinguishing media quantity, powder hose lines and monitor systems, nor areas with a risk of explosion, earthquake zones or extreme environmental conditions e.g. marine, offshore, mining or aircraft.This European standard does not apply to systems where there is a risk of class "D" fires according to EN 2.
