Railway applications - Electromagnetic compatibility - Part 2: Emission of the whole railway system to the outside world
This European Standard is intended to define the electromagnetic environment of the whole railway system including urban mass transit and light rail system. It describes the measurement method to verify the emissions, and gives the cartography values of the fields most frequently encountered. This European Standard specifies the emission limits of the whole railway system to the outside world. The emission parameters refer to the particular measuring points defined in Clause 5. 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 system may be affected by electromagnetic emissions and particular cases need to be considered individually. These specific provisions need to be used in conjunction with the general provisions in EN 50121-1. For existing railway lines, it is assumed that compliance with the emission requirements of EN 50121-3-1, EN 50121-3-2, EN 50121-4 and EN 50121 5 will ensur
