29、quirements on 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. This European Standard specifies in particular the important dimensions and arrangements for the connections of such tank wagons. NOT
30、ETo take account of the loading gauge restrictions within Great Britain this European Standard does not apply to tank wagons operating exclusively therein. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative re
31、ferences are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

35、on of pressure between the tank wagon and the vapour recovery system of the filling station in order to minimise volatile organic compound emissions 4 Requirements 4.1 General The devices in this European Standard shall allow the filling of tank wagons through the manhole with a loading arm. The tan
36、k 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. Petroleum tank wagons shall be fitted with a depressurisation vapour connector permitting the depressurisation of the tank prior to opening the man
37、lid and in conformity with this European Standard.

38、ld conform to this 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 situat
39、ed so that its vertical 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 500 mm and its top opening shall be in a horizontal plane. The manhole shall not restrict the operation of the vapour sealing device
40、 on the loading arm assembly. 4.3 Depressurisation vapour connector The depressurisation vapour connector shall conform with the vapour return coupling of EN 12561-2. The connecting face of the depressurisation vapour connector shall be in a horizontal plane. The connector is to be provided with an
41、easy-to-handle dust-proof cap with an attachment facility to a chain or a stainless steel wire cable. Where required by the regulations 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, t
42、hey shall conform to the regulations and ISO 4126-1. Where required by the regulations, the safety valve shall be preceded by a bursting disc. The bursting disc shall conform to prEN ISO 4126-2. Safety valve assemblies shall be fitted in the vapour space of the tank on nozzles DN 80 PN 10 according
43、to ISO 7005-1:1992. 4.5 Dimensions All dimensions are given in millimetres. Unless otherwise indicated in this European Standard tolerances of EN 20286-1 apply. 5 Positioning of equipment and reserved spaces The connecting faces of the manhole and depressurisation vapour connector shall be positione
44、d entirely within the dimensions shown in Figure 1. Furthermore, the depressurisation vapour connector shall be located close to the manhole and on the opposite side to the manlid hinge as shown in the Figure 1.
