19、Technical Committee 256 Railway Applications. Devices fitted to tank wagons that can be emptied through the top, and which incorporate a dip pipe, are covered by this European Standard. Devices fitted on the top of tank wagons that can only be bottom emptied are covered by EN 12561-5. BS EN 12561-4:
20、2011EN 12561-4:2011 (E) 5 1 Scope This European Standard is applicable to top devices of tank wagons used for liquid substances of RID carried in the liquid state and able to be top filled and emptied. Safety functions of these devices are subject to RID requirements and not described in this docume
21、nt. This European Standard specifies the type of equipment which is fitted on the top of such tank wagons and the important dimensions for their connections. This European Standard applies to new tank wagons built after the 1st January 2010. 2 Normative references The following referenced documents

NOTE It is recommended to have a sufficient space at the top of the flanges to install valves and/or couplings. The distance between air/vapour connection and dip pipe centres shall be in accordance with Figure 3.
32、4.4 Manhole The tank wagons shall be fitted with a manhole according to EN 12561-6 located at the top centre line of the tank and in the proximity of middle of the tank. Where the tank wagon is fitted with an internal bottom valve, the manhole shall be located so that its vertical projection on the
33、bottom of the tank is not closer than 100 mm from any part of that valve. 5 Positioning of equipment The equipment shall be positioned in the area as indicated in Figure 3.
