21、 depressurisation vapour connector, defined in this part and mainly used before filling, and a vapour return line including auto vent valve, defined in EN 12561-2 and mainly used during emptying. EN 12561-5:2011 (E) DIN EN 12561-5:2011-10 5 1 Scope This European Standard specifies the requirements o

22、n and characteristics of top devices of tank wagons fitted for bottom emptying only and filling through the manhole and used for liquid substances of RID. Safety functions of these devices are subject to RID requirements and not described in this document. This European Standard specifies in particu

23、lar the important dimensions and arrangements for the connections of such tank wagons. This European Standard applies to new tank wagons built after the 1st January 2010. NOTE To take account of the loading gauge restrictions within Great Britain this European Standard does not apply to tank wagons

28、alisation of pressure between the tank wagon and the vapour recovery system of the filling station in order to minimise volatile organic compound emissions EN 12561-5:2011 (E) DIN EN 12561-5:2011-10 6 4 Requirements 4.1 General The devices in this European Standard shall allow the filling of tank wa

29、gons through the manhole with a loading arm. The tank wagon shall be designed so that the loading arm does not come into contact with or damage the internal bottom valve when inserted into the tank wagon. Where tank wagons are fitted with a depressurisation vapour connector, it shall conform to this

30、 standard. Bottom emptying devices shall conform to EN 12561-2. 4.2 Manhole The tank wagons shall be fitted with swing bolt manholes according to EN 12561-6 situated on the top centre line and in the proximity of the longitudinal centre line of the tank. The manhole shall be situated so that its ver

31、tical projection on the bottom of the tank is not less than 100 mm from any part of the internal bottom valve. The manhole internal diameter shall be a nominal minimum of 500 mm and its top opening shall be in a horizontal plane. The manhole shall not restrict the operation of the vapour sealing dev

32、ice on the loading arm assembly. 4.3 Depressurisation vapour connector The connecting face of the depressurisation vapour connector shall be in a horizontal plane. The connector is to be provided with a closure with an attachment facility to a chain or a stainless steel wire cable. This attachment f

33、acility shall be fit for purpose and of minimum length to avoid contact with the electric overhead line. Where required by RID, the depressurisation vapour connector shall be fitted with a flame trap. 4.4 Safety valves Where tank wagons are fitted with pressure and/or vacuum relief valves, they shal

34、l conform to the regulations and EN ISO 4126-1. Where required by RID, the safety valve shall be preceded by a bursting disc. The bursting disc shall conform to EN ISO 4126-2. Safety valve assemblies shall be fitted in the vapour space of the tank on nozzles DN 80 PN 10 according to ISO 7005-1:1992.

35、 4.5 Dimensions All dimensions are given in millimetres. Unless otherwise indicated in this European Standard tolerances of EN ISO 286-1 apply. 5 Positioning of equipment and reserved spaces Except for specific cases agreed between the customer and the manufacturer: the connecting faces of the manho

36、le and depressurisation vapour connector shall be positioned entirely within the dimensions shown in Figure 1; EN 12561-5:2011 (E) DIN EN 12561-5:2011-10 7 furthermore, the depressurisation vapour connector shall be located close to the manhole and on the opposite side to the manlid hinge as shown i
