25、erformance 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 container assemblies - pressure regulators and gauges - actuators - main isolating valves and selector valves - nozzle

26、s. 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 environmental conditions e.g. marine, offshore, mining or aircraft additional considerations apply. This standard cov

27、ers 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 for which requirements and recommendations are given in prEN 12416-2:2000. Nor does it cover fire detectors or elect

28、rical control and indicating equipment. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited in the appropriate places in the text and the publications are listed hereafter. For dated refere
