Together with DIN EN 1947 and DIN E

6、N 14540, this standard is one of a series of fire-fighting hose standards that have been simultaneously revised by CEN/TC 192/WG 1 “Hoses for fire-fighting”. The former Annexes A to F including the test methods have been deleted and the test methods are now centrally specified in DIN EN 15889, Fire-

7、fighting hoses Test methods. In the present standard, reference is now made to the relevant annexes in DIN EN 15889. Because this document takes into consideration all hoses currently in use in Europe, semi-rigid hoses for fixed systems as in this document have been classified into two types and six

8、 classes, so that three possible inside diameters are given. During the next revision of this document, the extent to which such a complex classification is necessary will be reviewed on the basis of current market considerations. This European Standard does not specify a designation. The following

9、designation of fire-fighting hoses as in this standard is recommended: Designation of a fire-fighting hose as in this standard, of type A, class 1, with an inside diameter of 25 mm, a maximum working pressure of 1,2 MPa and a total length of 20 m: Fire-fighting hose DIN EN 694 A 1 25 1,2 20 The Nati

10、onal Annex NA gives recommendations as to which hoses as in this standard should be used to replace hoses as in the former DIN 14818-1 and DIN 14818-2 (both withdrawn). Amendments This standard differs from DIN EN 694:2007-07 as follows: a) The former Annexes A to F including the test methods have b

31、:2014 (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 unit

32、s are composed of a coupling, a valve, a semi-rigid hose which is water filled or empty fitted on a reel with its support and a nozzle. The fixed system is specified in EN 671-1, Fixed firefighting systems - Hose systems - Part 1: Hose reels with semi-rigid hose. DINEN 694:2014-10EN 694:2014 (E) 5 1

33、 Scope This European Standard specifies the requirements and test methods for semi-rigid 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 in

34、side diameter. Hoses conforming to this European 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. This European Standard applies exclusively to hoses for fire-fighting p

35、urposes 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 ambient temperatures below 20C can be supplied if they have been tested at the specified lower temperature in accordance with 6.4 and iden

36、tified by their marking in Clause 8 f). NOTE 2 All pressures are expressed in megapascals. 1 MPa = 10 bar 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
