Fire-fighting hoses - Non-percolating layflat hoses for fixed systems

This European Standard specifies the requirements and test methods for non-percolating layflat hoses for fixed systems. The hoses are intended for use at a maximum working pressure of 1,5 MPa over a range of inside diameters from 25 mm to 52 mm. The standard applies exclusively to hoses for fire-fighting purposes intended for use at a minimum ambient temperature of -20 °C in normal conditions, and a minimum temperature of -30 °C in colder climatic conditions. Hoses conforming to this standard should be used with fire hose couplings conforming to the relevant national standards for couplings. !Hoses in marine applications and/or aggressive environments to be used with wall hydrants as specified in EN 671-2 can conform to the requirements of this standard."

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2007 and conflicting national standards shall be withdrawn at the latest by October 2007. This document includes Amendment 1, approved by CEN on 2007-03-12. This document supersedes EN 14540:2004. The start and finish of text introduced or altered by amendment is indicated in the text by tags ! " The standard is based on recommendations from CEN/TC 191 “Fixed fire fighting systems” and should be read in conjunction with EN 671-2. !deleted text" At present there is no existing ISO standard on the same subject. !deleted text". Users of this European Standard are advised to consider the desirability of independent certification of product conformity with this European Standard based on testing and continuing surveillance, which may be coupled with assessment of a supplier's quality systems against EN ISO 9001.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 14540:2004+A1:2007 (E) 5 Introduction A fixed system is a manually operated unit installed in a building in order to make it possible for the occupants to control and extinguish a small fire. The system consists of fixed units mounted on walls or in cabinets permanently connected to a water supply. The fixed units are composed of a coupling, a valve with a pressure indicator, a layflat water filled hose with its support and a nozzle.



EN 14540:2004+A1:2007 (E) 6 1 Scope This European Standard specifies the requirements and test methods for non-percolating layflat hoses for fixed systems.

The standard applies exclusively to hoses for fire-fighting purposes intended for use at a minimum ambient temperature of -20 °C in normal conditions, and a minimum temperature of -30 °C in colder climatic conditions. Hoses conforming to this standard should be used with fire hose couplings conforming to the relevant national standards for couplings. !Hoses in marine applications and/or aggressive environments to be used with wall hydrants as specified in EN 671-2 can conform to the requirements of this standard."
