12、6 BS EN 12561-8:2011EN 12561-8:2011 (E) 3 Foreword This document (EN 12561-8:2011) has been prepared by Technical Committee CEN/TC 256 “Raiway applications”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an
13、identical text or by endorsement, at the latest by December 2011, and conflicting national standards shall be withdrawn at the latest by December 2011.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 patent rights. CEN and/or CENELEC shall not b
14、e 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 carriage of dangerous goods; Part 2: Bottom empty
15、ing 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 emptying of liquid products; Part 6: Manholes;
16、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 national standards organizations of the followi
17、ng 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, Netherlands, Norway, Poland, Portugal, Romania, Slovaki

BS EN 12561-8:2011EN 12561-8:2011 (E) 4 1 Scope This European Standard specifies positioning of connections, connection dimensions and coupling tightening devices for connections of steam heating installations used on tank wagons. This
19、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. For undated references, the latest edition of the ref
20、erenced document (including any amendments) applies. EN 14564, Tanks for transport of dangerous goods Terminology 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 14564 and the following apply. 3.1 heating installation device heating the tank contents
21、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 adjusted rate 4 Requirements The extremities of the he
22、ating 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 situated at the lowest point of the steam heating ins
23、tallation. 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 Except by agreement between customer and manufactu
24、rer, the connections shall be positioned entirely within the areas shown in Figure 1. BS EN 12561-8:2011EN 12561-8:2011 (E) 5 The steam connections shall not infringe the loading gauge. Spaces for connections may need to be different for domestic traffic in Great Britain (see Technical Specification
25、 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. Dimensions in millimetres Key 1 Where tank wagons are fitted with top connect
26、ions, they shall be positioned within this 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 BS EN 12561-8:2011EN 12561-8:2011 (E) 6 Dimensions in millimetres Figure 2 Dimensions of connections 6.2
27、 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 pressure of the connections shall be at least equal to the test pre
28、ssure of the steam heating installation. BS EN 12561-8:2011EN 12561-8:2011 (E) 7 7 Materials The materials of the fittings shall exhibit a suitable degree of safety in accordance with the maximum permissible working pressure and temperature of the heating installation. At these maximum working condi
29、tions, 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 connections. NOTE Regulation should require other marking in case of hot par
30、ts. 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.
