This European Standard applies to emission and immunity aspects of EMC for electrical and electronic apparatus and systems intended for use in railway fixed installations for power supply. This includes the power feed to the apparatus, the apparatus itself with its protective control circuits, trackside items such as switching stations, power autotransformers, booster transformers, substation power switchgear and power switchgear to other longitudinal and local supplies.
Filters operating at railway system voltage (for example, for harmonic suppression or power factor correction) are not included in this standard since each site has special requirements. Filters would normally have separate enclosures with separate rules for access. If electromagnetic limits are required, these will appear in the specification for the equipment.
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 are not intended to be applicable to the intentional transmission from a radio-transmitter as defined by the ITU.
The frequency range considered is from DC to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified.
Emission and immunity limits are given for items of apparatus which are situated:
a) within the boundary of a substation which delivers electric power to a railway;
b) beside the track for the purpose of controlling or regulating the railway power supply, including power factor correction;
c) along the track for the purpose of supplying electrical power to the railway other than by means of the conductors used for contact current collection, and associated return conductors. Included are high voltage feeder systems within the boundary of the railway which supply substations at which the voltage is reduced to the railway system voltage;
d) beside the track for controlling or regulating electric power supplies to ancillary railway uses. This category includes power supplies to marshalling yards, maintenance depots and stations;
e) various other non-traction power supplies from railway sources which are shared with railway traction.
The immunity levels given in this standard apply for:
- vital equipment such as protection devices;
- equipment having connections to the traction power conductors;
- apparatus inside the 3 m zone;
- ports of apparatus inside the 10 m zone with connection inside the 3 m zone;
- ports of apparatus inside the 10 m zone with cable length > 30 m.
Apparatus and systems which are in an environment which can be described as residential, commercial or light industry, even when placed within the physical boundary of the railway substation, shall comply with EN 61000-6-1:2007 for immunity and EN 61000-6-3:2007 for emission requirements.
Excluded from the immunity requirements of this standard is power supply apparatus which is intrinsically immune to the tests defined in Tables 1 to 6.
NOTE An example is an 18 MVA 230 kV to 25 kV power supply transformer.
These specific provisions are to be used in conjunction with the general provisions in EN 50121-1.
This part of the standard covers requirements for both apparatus and fixed installations. The sections for fixed installations are not relevant for CE marking.

This European Standard applies to signalling and telecommunication apparatus that is installed inside the railway environment. Signalling and telecommunication apparatus mounted in vehicles is covered by EN 50121-3-2:2016, signalling and telecommunication apparatus installed inside the substation and connected to substation equipment is covered by EN 50121-5:2016.
This European Standard specifies limits for emission and immunity and provides performance criteria for signalling and telecommunications (S&T) apparatus (including power supply systems belonging to S&T) which may interfere with other apparatus inside the railway environment, or increase the total emissions for the railway environment and so risk causing Electro-Magnetic Interference (EMI) to apparatus outside the railway system.
The requirements specified in this standard apply for:
— vital equipment such as interlocking or command and control;
— apparatus inside the 3 m zone;
— ports of apparatus inside the 10 m zone with connection inside the 3 m zone;
— ports of apparatus inside the 10 m zone with cable length > 30 m.
Other apparatus not covered by at least one of these given cases should be in compliance with EN 61000-6-2.
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 are 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.
The standard does not specify basic personal safety requirements for apparatus such as protection against electric shock, unsafe operation, insulation co-ordination and related dielectric tests. The requirements were developed for and are applicable to this set of apparatus when operating under normal conditions. Fault conditions of the apparatus have not been taken into account.
The frequency range considered is from DC to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified.
For products in the scope of EN 61000-3-2, EN 61000-3-3, EN 61000-3-11 or EN 61000-3-12 the requirements of those standards also apply.
These specific provisions are to be used in conjunction with the general provisions in EN 50121-1:2016.
The immunity and emission levels do not of themselves guarantee that the integration of apparatus will necessarily be satisfactory. The standard cannot cover all the possible configurations of the apparatus, but the test levels are sufficient to achieve satisfactory EMC in the majority of cases.

This European Standard applies to signalling and telecommunication apparatus that is installed inside
the railway environment. Signalling and telecommunication apparatus mounted in vehicles is covered
by EN 50121-3-2:2015, signalling and telecommunication apparatus installed inside the substation and
connected to substation equipment is covered by EN 50121-5:2015.
This European Standard specifies limits for emission and immunity and provides performance criteria
for signalling and telecommunications (S&T) apparatus (including power supply systems belonging to
S&T) which may interfere with other apparatus inside the railway environment, or increase the total
emissions for the railway environment and so risk causing Electro-Magnetic Interference (EMI) to
apparatus outside the railway system.
Apparatus which complies with the emission levels of EN 61000-6-4 will meet the emission
requirements of this standard provided that emissions from any DC power port are within the
emissions limits specified for AC power ports.

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 shall be considered individually.
These specific provisions are to be used in conjunction with the general provisions in
EN 50121-1:2015.
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 ensure the compliance with the
emission values given in this part.
For newly build railway systems it is best practice to provide compliance to the emission limits given in
this part of the standard (to be defined in the EMC plan according to EN 50121-1).

This European Standard applies to signalling and telecommunication apparatus which is installed in the railway environment. Signalling and telecommunication apparatus mounted in vehicles is covered by EN 50121-3-2. This standard specifies limits for emission and immunity and provides performance criteria for signalling and telecommunications (S&T) apparatus which may interfere with other apparatus in the railway environment, or increase the total emissions for the railway environment beyond the limits defined in the appropriate standard and so risk causing Electro-Magnetic Interference (EMI) to apparatus outside the railway system. Apparatus which complies with the emission levels of EN 61000-6-4 will meet the emission requirements of this standard provided that emissions from any d.c. power port are within the emissions limits specified for a.c. power ports. The immunity levels of EN 61000-6-2 will also be adequate except for the special case of apparatus as defined in note 1 of Table 1. This standard provides the immunity requirements for such apparatus. The immunity levels given for the apparatus will in most cases allow the apparatus to perform as intended in the railway environment (see note). The immunity level establishes a common reference for evaluating the performance of the apparatus when subject to interference resulting from direct exposure of the apparatus and associated cables to a radio frequency field, or by coupling of the interference from a remote source. If a port is intended to transmit or receive for the purpose of radio communication (intentional radiators. e.g. transponder systems), then the emission and immunity limits in this standard at the communication frequency do not apply. The standard does not specify basic personal safety requirements for apparatus such as protection against electric shock, unsafe operation, insulation co-ordination and related dielectric tests. The requirements were developed for and are applicable to this set of apparatus when operating under normal conditions. Fault conditions of the apparatus have not been taken into account. The requirements and test methods also apply to telecommunications and signalling data and power The requirements and test methods also apply to telecommunications and signalling data and power lines connected to the equipment under test (EUT). The frequency range considered is from d.c. to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified. For products in the scope of EN 61000-3-2 or EN 61000-3-3, the requirements of those standards apply. Testing methods are given in the basic standards listed in Clause 2, Normative references.
