26、1-1:2012) has been prepared by Technical Committee CEN/TC 191 “Fixed firefighting systems”, the secretariat of which is held by BSI. This document shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2012 and conflic

27、ting national standards shall be withdrawn at the latest by January 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This documen

28、t supersedes EN 671-1:2001. EN 671-1:2001 has been technically revised and editorial edited. The order of clauses has been changed. Annex ZA has been updated. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports

29、 essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. For convenience of application in testing, the normative annexes of this European Standard are arranged so that Annex A gives the sequence of testi

30、ng for conformity assessment and Annexes B, C, D, E and F are in the correct sequence for testing. EN 671 has the general title “Fixed firefighting systems Hose systems” and is in three parts: Part 1: Hose reels with semi-rigid hose; Part 2: Hose systems with lay-flat hose; Part 3: Maintenance of ho

31、se reels with semi-rigid hose and hose systems with lay-flat hose. 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, Croatia, Cyprus, Czech Republic, Denmark, E

32、stonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 671-1:2012EN 671-1:2012 (E) 6 Introduction Fire hose

33、reels in proper condition provide a very effective firefighting facility with a continuous supply of water available immediately. The requirements of this European Standard have been specified to ensure that hose reels can be operated efficiently by one person and that such systems have a long servi

34、ce life. 1 Scope This European Standard specifies requirements and methods of test for the construction and performance of fire hose reel systems with semi-rigid hose for installation in buildings, permanently connected to a water supply, for use by the occupants. It also provides requirements on ev

35、aluation of conformity and marking of these products. Its requirements may apply in general for other applications, for example in marine applications or in aggressive environments, but additional requirements can be necessary in such cases. This European Standard is applicable to both manual and au

36、tomatic fire hose reels for installation with and without cabinets. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
