NBN EN 16839:2017

This European Standard is valid for vehicles equipped with buffers and screw coupling systems.
In order to allow operation and coupling of trainsets or vehicles, this European Standard specifies the defined free space for the shunter called the "Berne rectangle" and the necessary free space for the installation of the rescue coupler.
This European Standard specifies the location, fixing and free spaces on the headstock of:
- buffers;
- screw coupling systems;
- end cocks;
- pneumatic half couplings;
- connections for electric cables.
It also specifies the calculation of the width of the buffer heads.
Unless otherwise displayed, all dimensions given in this European Standard are nominal values.
