This part of IEC 62236 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.
These specific provisions are to be used in conjunction with the general provisions in IEC 62236-1.
The limits refer to the particular measuring points defined in clause 5 and annex A. 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.
Excluded from the limits is apparatus which complies with the generic industrial emission standard IEC 61000-6-4.
