21、rt of liquid substances are equipped with top devices standardised within CEN 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 wa
22、gons that can only be bottom emptied are covered by EN 12561-5. EN 12561-4:2011 (E) DIN EN 12561-4:2011-10 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 function
23、s of these devices are subject to RID requirements and not described in this document. 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.

29、ing and emptying devices These devices shall allow the filling of tank wagons through the filling inlet or the dip pipe and the emptying through the dip pipe. They shall consist of the following minimum equipment: a dip pipe DN 80 on nozzle DN 150; an air/vapour connection DN 50 to DN 80; a filling
30、or spare nozzle, DN 150 to DN 300. Flanges shall have their connection dimensions in accordance with ISO 7005-1:1992 PN 10 series, face A or face B. Blind flanges shall be fitted with a handle mounted horizontally or vertically according to Figure 1 below. NOTE Other dimension for the nozzles are pe

NOTE It is recommended to have a sufficient space at the top of the flanges to install valves and/or couplings. The
34、distance between air/vapour connection and dip pipe centres shall be in accordance with Figure 3. 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 w
35、ith an internal bottom valve, the manhole shall be located so that its vertical projection on the 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.
