This European standard specifies requirements for materials, construction and performance of components intended for use in powder firefighting systems complying with EN 12416-2, which covers gas container systems with a maximum working pressure not exceeding 25 bar at 20°C. It does not cover stored pressure systems, pre-engineerd systems, powder hose lines and monitor systems. Methods of test are also given.
