6、-04-04 AA Schluche und Armaturen SpA zu CEN/TC 192/WG 1 und WG 8. Together with DIN EN 694 and DIN EN 14540, 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 former Annexes A to G, including the tes
7、t methods, have been deleted and the test methods are now centrally specified in DIN EN 15889, Firefighting 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,
8、 semi-rigid delivery hoses as in this document have been classified into three types, six classes and two categories, so that four 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 ba
9、sis of current market considerations. Type C PN 16 delivery couplings of aluminium alloy intended for use with semi-rigid delivery hoses as in this standard are specified in DIN 14330. This European Standard does not specify a designation. The following designation of firefighting hoses as in this s
10、tandard is recommended: Designation of a semi-rigid hose as in this standard, of category I, type A, class 1, with an inside diameter of 25 mm, which can only be used at temperatures above 20 C, and having a length of 30 m: Hose DIN EN 1947 I A 1 25 20 30 The National Annex NA gives recommendations
11、as to which hoses as in this standard should be used to replace hoses as in the former DIN 14817-1 and DIN 14817-2 (both withdrawn). Amendments This standard differs from DIN EN 1947:2007-07 as follows: a) the former Annexes A to G including the test methods have been deleted; reference is now made
12、to the relevant annexes in DIN EN 15889; b) the standard has been editorially revised.

34、gid hoses for use on fire-fighting vehicles and trailer pumps. The hoses are intended for use at a maximum working pressure of 1,5 MPa for normal pressure hoses (category I) and 4,0 MPa for high pressure hoses (category II). The hoses are further subdivided into types and classes (see Clause 4). Thi
35、s European Standard applies to hoses for fire-fighting purposes intended for use at ambient conditions within the temperature range 20 C to +60 C. NOTE 1 Hoses for use at ambient temperatures below 20 C can be supplied if they have been tested at the specified lower temperature in accordance with 6.
36、5 and identified by their marking in Clause 8 h). Hoses conforming to this standard are intended for use with fire hose couplings conforming to the relevant national standards for couplings. Requirements are also given for hose assemblies (see Clause 9) where these are fitted by the hose manufacture
