This European Standard shall be given the status of a n

14、ational standard, either by publication of an identical text or by endorsement, at the latest by December 2011, and conflicting national standards shall be withdrawn at the latest by December 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of

15、 patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12561-8:2004. This European Standard Railway applications Tank wagons consists of the following parts: Part 1: Identification plates for tank wagons for the car

16、riage of dangerous goods; Part 2: Bottom emptying devices for liquid products including vapour return; Part 3: Bottom filling and emptying devices for gases liquefied under pressure; Part 4: Devices for top filling and emptying of liquid products; Part 5: Devices for vapour return while filling or e

17、mptying of liquid products; Part 6: Manholes; Part 7: Platforms and ladders; Part 8: Heating connections. The changes made during this revision are editorial because of the change of the title of part 1 and the necessary updates of references. According to the CEN/CENELEC Internal Regulations, the n

18、ational standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlan

20、am heating installations used on tank wagons. This European Standard applies to new tank wagons built after the 1st January 2010. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. Fo

21、r undated references, the latest edition of the referenced document (including any amendments) applies.

22、ting installation device heating the tank contents and/or discharge equipment with steam 3.2 steam trap self contained valve which automatically drains the condensate from a steam containing enclosure while remaining tight to live steam, or if necessary, allowing steam to flow at a controlled or adj

23、usted rate 4 Requirements The extremities of the heating installation shall be fitted as follows: each inlet shall be fitted with a valve PN 16, and a connection according to Clause 6; each outlet shall be fitted with a valve PN 16 or a steam trap. In order to drain condensate the outlet shall be si

24、tuated at the lowest point of the steam heating installation. This outlet shall not be obstructed when the outlet valve is open. It shall be directed to the ground in such a way as not to present a danger to personnel or damage on brake parts or to other wagon equipment. 5 Positioning of connections

25、 Except by agreement between customer and manufacturer, the connections shall be positioned entirely within the areas shown in Figure 1. EN 12561-8:2011 (E) DIN EN 12561-8:2011-10 5 Dimensions in millimetres Key 1 Where tank wagons are fitted with top connections, they shall be positioned within thi

26、s area 2 Where tank wagons are fitted with bottom connections, they shall be positioned on both sides within this area Figure 1 Positioning of connections The steam connections shall not infringe the loading gauge. Spaces for connections may need to be different for domestic traffic in Great Britain

27、 (see Technical Specification for Interoperability for Freight Wagons). 6 Connection 6.1 Dimensions Except for other types of connections agreed between the customer and the manufacturer, the dimensions of the connection shall be as shown in Figure 2. EN 12561-8:2011 (E) DIN EN 12561-8:2011-10 6 Dim

28、ensions in millimetres Figure 2 Dimensions of connections 6.2 Tightening device The connection to the steam supply pipe shall be made in a leak-tight manner. An example of a tightening device is shown in Figure 3. Figure 3 Example of tightening device 6.3 Test pressure of connections The test pressu

29、re of the connections shall be at least equal to the test pressure of the steam heating installation. EN 12561-8:2011 (E) DIN EN 12561-8:2011-10 7 7 Materials The materials of the fittings shall exhibit a suitable degree of safety in accordance with the maximum permissible working pressure and tempe

30、rature of the heating installation. At these maximum working conditions, the materials shall be compatible with the steam where they come in contact with it. 8 Marking The maximum allowable working pressure of the heating installation shall be clearly marked on the tank wagon close to the connection

31、s. NOTE Regulation should require other marking in case of hot parts. Where the heating device can also be used for heating tank equipment, a diagrammatic representation of the use of the different devices shall be fitted on the tank wagon close to the connections.
