BS EN 50121-2:2006 sets the emission limits from the railway to the outside world at radio frequencies. It defines the applied test methods and gives information on typical field strength values at traction and radio frequency (cartography).
BS EN 50121-2:2006 sets the emission limits from the whole railway system including urban vehicles for use in city streets. It describes the measurement method to verify the emissions, and gives the cartography values of the fields most frequently encountered.
The limits refer to the particular measuring points defined in the document. These emissions should be assumed to exist at all points in the vertical planes which are 10 m from the centre lines of the outer electrified railway tracks, or 10 m from the fence of the substations.
Also, the zones above and below the railway may be affected by electromagnetic emissions and particular cases shall be considered individually.
These specific provisions are to be used in conjunction with the general provisions in BS EN 50121-1.
This part of the standard covers EMC for fixed installations and therefore is not relevant for CE marking.
BS EN 50121-2:2006 supersedes BS EN 50121-2:2002 which has been withdrawn.
