15、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of an identical text or by endorsement, at the latest by December 2011, and conflicting national standards shall be withdrawn at the latest by December 2011.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 patent rights. CEN and/o

16、r CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12561-7:2004. 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;

17、 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 emptying of liquid product

18、s; Part 6: Manholes; Part 7: Platforms and ladders; Part 8: Heating connections.

EN 12561-7:2011 (E) DIN EN 12561-7:2011-10 4 1 Scope This European Standard applies to ladders, platforms and walkways on tank wagons fitted with top devices. It does not apply to crossing gangways nor to steps in s

21、o far as they are covered by UIC leaflets. This European Standard defines the important dimensions for manufacturers and operators of such tank wagons and takes into consideration the relevant and applicable construction and safety guidelines. This European Standard applies to new tank wagons built

22、after the 1st January 2010. In consideration of the smaller loading gauge within the UK, this European Standard does not apply to wagons operating exclusively therein. 2 Normative references The following referenced documents are indispensable for the application of this document.

23、es, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

25、poses 3.2 walkway structure supporting grating to provide access between ladders and platforms 3.3 protective device device to deflect operating personnel from protruding parts of a moving tank wagon in accordance with UIC 535-2 4 Ladders 4.1 General Where tank wagons are fitted with ladders, they s

26、hall either be fitted with one fixed ladder located at the end or with a fixed ladder on each side of the tank wagon. NOTE 1 The end ladder is usually fitted at the crossing gangway. Ladders shall be fitted with 2 lateral handrails. EN 12561-7:2011 (E) DIN EN 12561-7:2011-10 5 NOTE 2 For traffic of

27、continental tank wagons running in Great Britain, the kinematic gauge for Great Britain rules defined in the Technical Specification for Interoperability for freight wagons (TSI) also apply and to avoid conflict between these rules, local arrangement for handrail should be allowed to stay in the gau

28、ge. The pitch of the ladder as shown in Figure 1 shall be between 75 and 90. Where the pitch is less than 75 steps shall be used in place of rungs. The depth of the steps shall be at least 80 mm. Key 1 Pitch 2 Handrails 3 String 4 Rung Figure 1 Terms The rungs and the steps shall be welded to the st

29、rings and shall be slip-resistant. Rung slip resistance can, for example, be achieved by using square or flat bars with a cross section as shown in Figure 2. Figure 2 Examples of rung cross sections EN 12561-7:2011 (E) DIN EN 12561-7:2011-10 6 If they are from square or rectangular section, they sha

30、ll not have sharp edges. Steps shall have a grating according to the requirements of Clause 7. 4.2 Main dimensions The main dimensions of ladders shall be as shown in Figure 3 and Figure 4. All the rungs shall be equally spaced. The sides of square steel rungs shall be between 20 mm to 30 mm. Differ

31、ent shaped rungs of equivalent strength are permitted provided they are slip resistant (e.g. rectangular steel rungs with a cross section of 40 mm 8 mm). The clearance above and behind each rung shall be as shown in Figure 5. The handrail shall be made from circular cross section tubes or bars of at

32、 least 20 mm outside diameter. The ladder handrail shall be connected to the toe plates of the walkways or platforms. The clearance around the handrail shall be at least 100 mm. Where lateral ladders protrude more than 250 mm from the chassis of the tank wagon, a protective device shall be fitted at

33、 a height of between 1 200 mm to 1 400 mm above the rail (see Figure 6). The lateral ladders shall not infringe the loading gauge. 4.3 Design values Ladders shall be designed to withstand a static load of 2,0 kN in the centre of any rung. The maximum allowable elastic deformation under this load sha

34、ll not exceed 1/200 of the width. 4.4 Marking A warning sign for overhead electrical danger shall be located near to each ladder in accordance with EN ISO 6346:1995, Annex C or Technical Specification for Interoperability for Freight Wagons.

37、orizontal; to have a free width of at least 300 mm; to have sufficient clearance around manlid swing bolts to allow easy operation; to be surrounded by a toe plate of 20 mm minimum height, except where a ladder or a walkway is attached; to be fitted with a fixed point in accordance with EN 795 to wh

38、ich a safety line can be attached; to have a grating according to the requirements of Clause 7. The platform, including the toe plates shall not infringe the loading gauge. The width of the platform and the height of the toe plates may need to be reduced for domestic traffic in Great Britain (see Te

39、chnical Specification for Interoperability for Freight Wagons). EN 12561-7:2011 (E) DIN EN 12561-7:2011-10 5.2 Design values The platform shall be designed to withstand a load of 3 kN uniformly distributed over an area of 600 mm 300 mm. The deflection under this load shall not exceed 10 mm or 1/200

40、of the span, whichever is the smaller. 6 Walkways 6.1 General Walkways shall be built in accordance with the following requirements: to be flat and may have a maximum longitudinal slope of 5; to be surrounded by a toe plate of minimum 20 mm height, except where a ladder or a platform is attached; to

41、 be fitted with a safety rail with a minimum clearance of 100 mm around it (see Figures 3 and 4); to have a grating according to the requirements of Clause 7. It is recommended to have walkways at the same level as the platform. 10 6.2 Main dimensions The width of the walkways shall not be less than

42、 500 mm and shall not infringe the loading gauge. The width of the walkways, the height of the toe plates and the clearance around the safety rail may need to be reduced for domestic traffic in Great Britain (see Technical Specification for Interoperability for Freight Wagons). 6.3 Design values The

43、 walkway shall be designed to withstand a load of 3 kN uniformly distributed over an area of 600 mm 300 mm. The deflection under this load shall not exceed 10 mm or 1/200 of the span, whichever is the smaller. 7 Characteristics of the grating 7.1 Resistance to friction The average value of the frict

44、ion coefficient measured in three directions (lengthwise, breadthwise and diagonally) shall reach the following minimum values: a) in dry condition 0,65; b) in wet condition (water) 0,65; c) in oiled condition 0,30. Friction coefficient values shall be ascertained by means of a 100 mm 100 mm movable

45、 plate, on which a rubber pad with 80 I.R.H.D. hardness shall be glued; this plate shall be loaded to 750 N. For the measurements carried out with water or oil, the grating shall be fully immersed. EN 12561-7:2011 (E) DIN EN 12561-7:2011-10 7.2 Grating structure To ensure that the gratings are suffi

46、ciently well adapted to winter conditions, a ratio of at least 50 % of void area to total area shall be observed. Only apertures with a minimum area of 400 mm shall be taken into account to determine this ratio. The void area is the free space afforded, in the vertical direction, by the grating aper

47、tures. 8 Fixing Where ladders, platforms and walkways are fixed to the shell of the tank wagon, doubler plates shall be used. The fixings shall be properly secured to discourage theft and minimise the risk of working loose. The attachment of the ladder to the vehicle shall not introduce unacceptable

48、 stresses during all conditions of operation. 11 EN 12561-7:2011 (E) DIN EN 12561-7:2011-10 Bibliography 1 ISO 48, Rubber, vulcanized or thermoplastic Determination of hardness (hardness between 10 IRHD and 100 IRHD) 2 ISO 1496-3, Series 1 freight containers Specification and testing Part 3: Tank co
