(38 9240) This document specifies requirements and test methods for materials, construction and performance of components intended for use in powder firefighting systems complying with EN 12416-2:2001+A1:2007. 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 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 document covers components for use in powder extinguishing systems complying with EN 12416-2:2001+A1:2007. It does not cover, for example, pipes and fittings which are covered by more general standards for which requirements and recommendations are given in EN 12416-2:2001+A1:2007. Nor does it cover fire detectors or electrical control and indicating equipment.
