27、007 (E) 4 1 Scope This European Standard specifies requirements and test methods for materials, construction and performance of components intended for use in powder firefighting systems complying with prEN 12416-2:2000. The components covered are as follows: - powder containers - expellant gas cont
28、ainer 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 construction works. In areas with a risk of explosion, earthquake zones, extreme env
29、ironmental 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. It does not cover, for example, pipes and fittings which are covered by more general standards fo
30、r which requirements and recommendations are given in prEN 12416-2:2000. Nor does it cover fire detectors or electrical control and indicating equipment. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative refe
