BS EN 12561 is a European standard that discusses tank wagons for railways. BS EN 12561-5 is the fifth part of a multi-part series that outlines the requirements 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 to manufacture efficient devices for vapour return and ensure their safety and performance while filling or emptying liquid products.
BS EN 12561-5 layouts the important dimensions and arrangements for the connections of such tank wagons.
BS EN 12561-5 applies to new tank wagons built after the 1st of January 2010.
Note 1: The safety functions of these devices are subject to RID requirements and not described in BS EN 12561-5.
Note 2: To take into account the loading gauge restrictions within Great Britain BS EN 12561-5 do not apply to tank wagons operating exclusively therein.
BS EN 12561-5 on the tank wagon device for vapour return is useful for:
The top vapour return devices are elements of the devices for filling and emptying devices. depressurisation vapour connector is a connection enabling the equalisation of pressure between the tank wagon and the vapour recovery system of the filling station to minimise volatile organic compound emissions.
BS EN 12561-5 assists you with the requirements of the manhole, depressurisation vapour connector, safety valves and dimensions. This assists in manufacturing efficient devices for vapour return that are durable and of high quality.
BS EN 12561-5 also covers the positioning of the equipment and reserved spaces that assist in assessing the characteristics of devices used in tank wagons for vapour return.
With obedience and compliance to BS EN 12561-5, you can enhance the efficacy of devices for top vapour return and manufacture a standardised product that has global acceptance in the market.
