It is applicable to railway vehicles fitted with water taps for use in toilets, washing facilitie
21、s, water dispensers and catering equipment and the railway infrastructure at designated servicing sites. This European Standard is not applicable to filling railway vehicles with water for the purpose of engine cooling, steam heating or work equipment on on-track machines. 2 Normative references The
22、 following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 806 (al

25、nt, the following terms and definitions apply. 3.1 railway infrastructure all installations required for the running of railway vehicles including operating and support facilities EXAMPLE Tracks, crossings, catenaries, signals, maintenance depots. 4 Requirements 4.1 On vehicles 4.1.1 Water system 4.
26、1.1.1 Standard temperature range Where a railway vehicle has a requirement for water taps for use in toilets, washing facilities, water dispensers and catering equipment using water it shall be fitted with a system to supply water for this purpose. The water system shall be designed and insulated su
27、ch that: with the vehicle heating system operational the water system shall function normally at external temperature of 20 C; the water system shall function normally after the heating system is turned off with the vehicle internal temperature of 20 C and external temperature of 10 C for 12 h, and
28、then the vehicle internal temperature returned to 20 C. DIN EN 16362:2014-03 EN 16362:2013 (E) 5 The verification of this requirement shall be by successful completion of the test in accordance with Annex C. 4.1.1.2 Low ambient temperature range It is permissible for water systems to be designed to
29、withstand lower minimum temperature than shown in 4.1.1.1. The technical documentation shall state the minimum ambient temperature the system is designed for, where this is below 20 C. NOTE For example T1 in EN 501251 requires a minimum of 25 C. 4.1.1.3 All water systems The water system from the in
30、let up to and including the storage tank shall be able to withstand the maximum pressure and flow rate shown in 4.2.3. NOTE Where a water level indicator is fitted then suitable examples are shown in Annex A. 4.1.2 Coupling for water supply For each independent water system within scope of this stan
31、dard, a filling coupling shown in Figure 1 shall be fitted on each side of the vehicle, or each side on a vehicle end. The filling coupling shall be positioned with the centre of the coupling aperture at a maximum 1 600 mm above rail level. Filling couplings shall be marked as shown in EN 15877-2:20
32、13, 4.5.15, Figure 48 if compliant with 4.1.1.1 and EN 15877-2:2013, 4.5.15, Figure 47 if compliant with 4.1.1.2. All other water systems used on railway vehicles, for example for engine cooling, steam heating or work equipment on on-track machines, shall be incapable of use with the filling couplin
33、g shown in Figure 1. The inlet pipes between the filling coupling and the water tanks shall either have: an internal diameter of 36 mm, equal to that of the bore of the bayonet joint; or, is permitted to have a smaller diameter inlet pipe where it can be demonstrated that the vehicle can be filled w
34、ithin 4 min using a supply pressure of 3 bar.

35、 water filling for engine cooling, steam heating or work equipment on on-track machines. 4.1.3 Protection of coupling The filling coupling shall be fitted with a shield to protect against contamination by dirt and snow. This shield shall cover the outside of the filling coupling with a minimum overl
36、ap of 12 mm all around the cover. The shield shall be designed to allow condensation and overflow water to drain off freely, this is to ensure that the filling coupling will not become frozen. A typical example of a water filling coupling shield is shown in Figure B.1. 4.1.4 Drainage Each vehicle wa
37、ter supply system shall be capable of completely draining by the operation of one switch or lever, it is also permitted that one button can discharge a complete train. It is permitted for the discharge to be operated additionally by a thermostat-controlled discharge valve which is actuated automatic
38、ally before the water in the supply circuit freezes. When the vehicle is level, it shall be possible to empty the water supply system completely with a minimum flow rate of 1 l/s, leaving no trapped liquid. It is permitted for this time limit to be deliberately exceeded in the case of thermostat-con
39、trolled graduated drainage, whenever there is a risk of parts of the system freezing up. It is also permitted for this time limit to be exceeded by individual items of catering equipment. All water tanks and pipes shall be provided with a drainage system designed to ensure complete emptying and effi
40、cient rinsing. This is permitted to be individually per tank in addition to drainage as part of the centralised drainage system. The devices facilitating the drainage of the water system for toilet compartments shall be identified immediately adjacent to the fitting controlling the operation of thes
41、e devices with markings as shown in EN 15877-2:2013, 4.5.15, Figure 48 if compliant with 4.1.1.1 and EN 15877-2:2013, 4.5.15, Figure 47 if compliant with 4.1.1.2. 4.1.5 Drinking water system Systems used to supply drinking water shall be constructed of materials, equipment and fittings that have pro
42、ven suitability for use. As a minimum they shall use materials that are shown in EN 806-2:2005, Annex A. 4.2 On railway infrastructure 4.2.1 Depot supply hose to vehicle The supply hose shall be flexible and have a coupling on the end to match with the water filling coupling shown in Figure 1. The d
43、epot supply pipework and hose shall be suitable for drinking water compliant with EN 12502-1 and EN 806-2. The hose shall be designed so that it is always capable of draining when not in use. 4.2.2 Protection of end of supply hose The filling system shall be designed so that the end coupling is alwa
44、ys capable of either hanging clear of the ground or in a mild disinfectant solution, fulfilling the requirements of the EN 806 series. It is permitted for the supply hose coupling to be capable of being fitted with a dirt cover, or capable of being coupled to a suitable protective device for storage
45、. The cover or fixed protective device shall be designed to prevent the ingress of dust and contaminants into the flexible supply pipe whilst retaining the ability to drain the pipe. DIN EN 16362:2014-03 EN 16362:2013 (E) 8 4.2.3 Water supply and equipment The devices shall withstand a water pressur
46、e of 6 bar and be able to deliver a water flow rate of 150 l/min. European experience has shown that an acceptable vehicle filling time requires a minimum water pressure of 3 bar and a minimum flow rate of 80 l/min. NOTE The TSIs HSR INF and CR INF require that the water supplied to the train is dri
47、nking water, as specified in Directive 98/83/EC. 4.2.4 Security of supply There shall be a device to prevent water going backwards towards the water supply to prevent back siphoning. A permissible method for achieving this requirement, for example non-return valve, sealed break tank, etc., will vary
48、 according to the location of the servicing point. It is recommended to seek guidance from the local water supply company. 4.2.5 Frost protection Where there is a possibility of ambient temperatures below 0 C the flexible water supply hose shall be self draining to prevent water remaining in the hose. In addition it is permissible to provide sufficient trace heating to prevent the water in the supply pipe to the flexible hose from freezing. 4.3 Information and instruction 4.3.1 For railway vehicles Where water is inten
