BS EN 12561 is a European standard on railway applications that discusses tank wagons. BS EN 12561-4 provides devices for top filling and emptying of liquid products in tank wagons to prevent spillage of liquid products from tank wagons.
BS EN 12561-4 is the fourth part of a multi-part series that specifies the type of equipment that is fitted on the top of such tank wagons and the important dimensions for their connections.
BS EN 12561-4 applies 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. BS EN 12561-4 also applies to new tank wagons built after the 1st January 2010.
Note: Safety functions of these devices are subject to RID requirements and not described under BS EN 12561-4.
BS EN 12561-4 on devices for top filling and emptying of liquid products in tank wagons is relevant to:
Tank wagons for the transport of liquid substances are equipped with top devices that can be emptied through the top, and which incorporate a dip pipe. These devices shall allow the filling of tank wagons through the filling inlet or the dip pipe and the emptying through the dip pipe.
BS EN 12561-4 provides you with the requirements, dimensions, and positioning of the equipment.
This assists in manufacturing efficient devices for top filling and emptying of liquid products in tank wagons that are durable as well as high-quality for installation in tank wagons.
With compliance and obedience to BS EN 12561-4, you can enhance the efficacy and performance of top devices and manufacture a standardised product for use in tank wagons.EN 12561-4:2011
