Railway applications - Electromagnetic compatibility - Part 3-2: Rolling stock - Apparatus
EN 50121-3-2:2016/A1:2019

This European Standard applies to emission and immunity aspects of EMC for electrical and electronic apparatus intended for use on railway rolling stock. EN 50121-3-2 applies for the integration of apparatus on rolling stock.
The frequency range considered is from DC to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified.
The application of tests shall depend on the particular apparatus, its configuration, its ports, its technology and its operating conditions.
This standard takes into account the internal environment of the railway rolling stock and the external environment of the railway, and interference to the apparatus from equipment such as hand-held radio-transmitters.
If a port is intended to transmit or receive for the purpose of radio communication (intentional radiators, e.g. transponder systems), then the radiated emission requirement in this standard is not intended to be applicable to the intentional transmission from a radio-transmitter as defined by the ITU.
Immunity limits do not apply in the exclusion bands as defined in the corresponding EMC related standard for radio equipment.
This standard does not apply to transient emissions when starting or stopping the apparatus.
The objective of this standard is to define limits and test methods for electromagnetic emissions and immunity test requirements in relation to conducted and radiated disturbances.
These limits and tests represent essential electromagnetic compatibility requirements.
Emission requirements have been selected so as to ensure that disturbances generated by the apparatus operated normally on railway rolling stock do not exceed a level which could prevent other apparatus from operating as intended. The emission limits given in this standard take precedence over emission requirements for individual apparatus on board the rolling stock given in other standards.
Likewise, the immunity requirements have been selected so as to ensure an adequate level of immunity for rolling stock apparatus.
The levels do not however cover all cases which may occur with an extremely low probability of occurrence in any location. Specific requirements which deviate from this standard shall be specified.
Test requirements are specified for each port considered.
These specific provisions are to be used in conjunction with the general provisions in EN 50121-1.

SIST EN 50121-3-1:2017/A1:2019(Amendment)
Railway applications - Electromagnetic compatibility - Part 3-1: Rolling stock - Train and complete vehicle
EN 50121-3-1:2017/A1:2019

This European Standard specifies the emission and immunity requirements for all types of rolling stock. It covers traction stock, hauled stock and trainsets including urban vehicles for use in city streets. This European standard specifies the emission limits of the rolling stock to the outside world.
The scope of this part of the standard ends at the interface of the rolling stock with its respective energy inputs and outputs. In the case of locomotives, trainsets, trams etc., this is the current collector (pantograph, shoe gear). In the case of hauled stock, this is the AC or DC auxiliary power connector. However, since the current collector is part of the traction stock, it is not entirely possible to exclude the effects of this interface with the power supply line. The slow moving test has been designed to minimize these effects.
There may be additional compatibility requirements within the railway system identified in the EMC plan (e.g. as specified in EN 50238).
Basically, all apparatus to be integrated into a vehicle meet the requirements of EN 50121-3-2. In exceptional cases, where apparatus meets another EMC Standard, but full compliance with EN 50121-3-2 is not demonstrated, EMC is ensured by adequate integration measures of the apparatus into the vehicle system and/or by an appropriate EMC analysis and test which justifies deviating from EN 50121-3-2.
Electromagnetic interference concerning the railway system as a whole is dealt with in EN 50121-2.
These specific provisions are to be used in conjunction with the general provisions in EN 50121-1.
The frequency range considered is from 0 Hz (DC) to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified.

Railway applications - Testing of rolling stock for electromagnetic compatibility with axle counters
EN 50592:2016

This European Standard defines, for the purpose of ensuring compatibility between rolling stock and axle
counter systems, the measurement and evaluation methods of rolling stock emissions to demonstrate
compatibility. The established limits for compatibility are defined as magnetic field strength that can disturb
the axle counter detectors, as part of the axle counter system.
In the relevant frequency range of the axle counter detectors the magnetic field is dominant and only this
type of field is considered. Experience has shown that the effects of electric fields are insignificant and
therefore not considered.
NOTE 1 For axle counters systems whose limits are not defined in terms of magnetic fields at a detector level,
National Rules apply where they exist (for more details, see also 4.1).
NOTE 2 The influence from metal parts or inductively coupled resonant circuits on the vehicle, eddy current brakes or
magnetic brakes is out of the scope of this EN. Compatibility is established through individual testing according to the
EN 50238 series or National Notified Technical Rules.
