DIN EN 14540:2014-09

This document has been prepared by Technical Committee CEN/TC 192 "Fire and rescue service equipment" (secretariat: BSI, United Kingdom), Working Group WG 1 "Hoses for firefighting". The responsible German body involved in its preparation is the Normenausschuss Feuerwehrwesen (DIN Standards Committee Firefighting and Fire Protection), Working Committee NA 031-04-04 AA "Schläuche und Armaturen - SpA zu CEN/TC 192/WG 1 und WG 8" ("Hoses and valves - Mirror Committee of CEN/TC 192/WG1 and WG 8"). Together with DIN EN 694 and DIN EN 1947, this standard is one of a series of firefighting hose standards that have been simultaneously revised by CEN/TC 192/WG 1 "Hoses for firefighting". The Annexes including the test methods have been deleted and the test methods are now centrally specified in DIN EN 15889 "Firefighting hoses - Test methods". In the requirement clauses of this standard, reference is now made to the relevant annexes in DIN EN 15889. Layflat hoses as in this document serve to convey fire extinguishing media (water, water with additives, etcetera) and are used with wall hydrants as in DIN EN 671-2 or DIN 14461-6. When empty, such hoses can be rolled or folded flat. Because this document takes into consideration all hoses which are in use in Europe at the time of its preparation, eight possible inside diameters are given. During the next revision of this document, the extent to which such a number of inside diameters is necessary will be reviewed on the basis of current market considerations. Since EN 14540:2014 does not specify a designation, it is recommended to designate firefighting hoses complying with this European Standard as indicated in its national foreword.
