ScopeThis European Standard specifies requirements and test methods for materials, construction and performance ofcomponents intended for use in powder firefighting systems complying with prEN 12416-2:2000.The components covered are as follows:- powder containers- expellant gas container assemblies- pressure regulators and gauges- actuators- main isolating valves and selector valves- nozzles.The components are suitable for powder firefighting systems for general use in buildings and other constructionworks. In areas with a risk of explosion, earthquake zones, extreme environmental conditions e.g. marine,offshore, mining or aircraft additional considerations apply.This standard covers components for use in powder extinguishing systems complying with prEN 12416-2:2000. Itdoes not cover, for example, pipes and fittings which are covered by more general standards for whichrequirements and recommendations are given in prEN 12416-2:2000. Nor does it cover fire detectors or electricalcontrol and indicating equipment.2
Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited in the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications, apply to this Europeanstandard only when incorporated in it by amendment or revision.
