EN 694:2001+A1:2007 (E) 3 Foreword This document (EN 694:2001+A1:2007) has been prepared by Technical Committee CEN/TC 192 "Fire service equipment", the secretariat of which is held by BSI. 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of an identical text or by endorsement, at the latest by October 2007 and conflicting national standards shall be withdrawn at the latest by October 2007.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 694:2001. The start and finish of text introduced or altered by amendment is indicated in the text by tags ! " The modifications of the related CEN Corrigenda have been implemented at the appropriate places in the text and are indicated by the tags ˜™. The standard is based on recommendations from CEN/TC 191 “Fixed fire-fighting systems” and should be read in conjunction with EN 671-1. At present there is no existing ISO Standard on the same subject but ISO 4642:1978 “Rubber products - Hoses, non-collapsible, for fire-fighting service” is under revision by ISO/TC 45. Requirements for semi-rigid hoses for use with fire-fighting pumps and vehicles are given in EN 1947; those for non-percolating layflat hoses are given in EN 1924-1 (pumps and vehicles) and EN 1924-2 (fixed systems). !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 system 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 694:2001+A1:2007 (E) 4 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, a semi-rigid water filled hose with its support and a nozzle.



EN 694:2001+A1:2007 (E) 5
1 Scope This European Standard specifies the requirements and test methods for semi-rigid reel hoses for fire-fighting purposes for use with fixed systems. The hoses are intended for use at a maximum working pressure of 1,2 MPa for hoses of 19 mm and 25 mm inside diameter and 0,7 MPa for hoses of 33 mm inside diameter. Hoses conforming to this standard are intended for applications where long intervals can occur between the occasions of use, for example on fixed fire hose reels in buildings and other construction works. The standard applies exclusively to hoses for fire-fighting purposes intended for use at ambient conditions in non-aggressive or non-corrosive atmospheres within the temperature range -20 °C to +60 °C. NOTE 1 Hoses for use at temperatures lower than -20 °C may be supplied at the request of the purchaser. NOTE 2 All pressures are expressed in megapascals. 1 MPa = 10 bar. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies (including amendments).

3 Definitions For the purposes of this standard the following definition applies, together with those for working pressure, proof pressure and burst pressure given in ISO 8330:1998. 3.1 semi-rigid hose hose which maintains its round cross-section even when unpressurized 4 Classification 4.1 General All types and classes of hoses shall be so flexible that they can be rolled and kept on a drum of minimum diameter 200 mm for 19 mm and 25 mm inside diameter hose and of minimum diameter 280 mm for 33 mm inside diameter hose. Hoses shall be one of two types distinguished by their construction. Each hose type shall be further divided into classes distinguished by the materials used for lining and cover. 4.2 Classification by types (hose construction) Type A hoses shall consist of: a) a seamless rubber or plastics lining;
b) a textile reinforcement with or without a rigid spiral helix; c) a rubber or plastics cover. Type B hoses shall consist of: a) a seamless rubber or plastics lining; b) a circular woven textile reinforcement with a rigid spiral helix; c) an uncovered or rubber or plastics cover. 4.3 Classification by class (materials for lining and cover) The hose types shall be further subdivided into six classes dependent on the materials used in the construction in accordance with Table 1.
