BRITISH STANDARD BS EN 12094-52006 Fixed firefighting systems Components for gas extinguishing systems Part 5 Requirements and test s for high and low pressure selector valves and their actuators The European Standard EN 12094-52006 has the status of a British Standard ICS 13.220.20 Licensed Copy London South Bank University, London South Bank University, Sat Jul 15 192534 BST 2006, Uncontrolled Copy, c BSI BS EN 12094-52006 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 June 2006 BSI 2006 ISBN 0 580 48805 5 National foreword This British Standard is the official English language version of EN 12094-52006. It supersedes BS EN 12094-52001 which is withdrawn. The UK participation in its preparation was entrusted by Technical Committee FSH/18, Fixed firefighting systems, to Subcommittee FSH/18/6, Gaseous extinguishing media and systems, which has the responsibility to A list of organizations represented on this subcommittee can be obtained on request to its secretary. Additional ination In 4.1.9, Figures ZA.1 and ZA.3 the term ‘flow resistance coefficient’ is used. This characteristic, which is the friction or resistance that the valve, pipe or fitting presents to the flow of fluid, is also referred to in the UK as ‘pressure loss coefficient’. Subclause 5.9 currently requires tests on selector valves using both gas and water. For the next revision of the European Standard the UK will request that all selector valves are flow tested using only water to determine the flow resistance coefficient. In addition to simplifying the text, this will have the added benefit of avoiding an unnecessary discharge of the extinguishant to the environment. It should be noted that the coefficients used for the pipe fittings in the EN 12094 series were all determined using water.
