This European Standard specifies requirements on and characteristics of bottom filling and emptying devices on tank wagons used for the carriage of gases liquefied under pressure having a test pressure up to 2,9 MPa. This European Standard specifies the important dimensions and arrangements for the filling and emptying connections. Safety functions of these devices are subject to RID requirements and not described in this document. This European Standard applies to new tank wagons built after the 1st January 2010. NOTE It is intended to include quick couplings in a future revision of this European Standard.
