1 Scope
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 d.c. 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 emission and immunity limits in this standard at the
communication frequency do not apply.

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.

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 extreme 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.

3 Definitions
For the purpose of this Part 3-2 of the European Standard, the following definitions apply:

3.1
rolling stock apparatus
a finished product with an intrinsic function intended for implementation into the rolling stock installation

3.2
port
the particular interface of the specified apparatus with the external environment e.g. a.c. power port,
d.c. power port, I/O (input/output) port

3.3
enclosure port
the physical boundary of the apparatus through which electromagnetic fields may radiate or impinge

The main categories of ports for rolling stock apparatus are presented in Figure 1.

4 Performance criteria
The variety and the diversity of the apparatus within the scope of this standard make it difficult to define
precise criteria for the evaluation of the immunity test results.

A functional description and a definition of performance criteria, during or as a consequence of the
EMC testing, shall be provided by the manufacturer and noted in the test report, based on the criteria
A, B, C defined in EN 50121-1.

5 Conditions during testing
It is not always possible to test every function of the apparatus. The tests shall be made at a typical
operating mode considered by the manufacturer to produce the largest emission or maximum
susceptibility to noise as appropriate in the frequency band being investigated consistent with normal
applications. The manufacturer shall define the conditions during testing in a test plan.

If the apparatus is part of a system, or can be connected to auxiliary apparatus, then the apparatus
shall be tested while connected to the minimum configuration of auxiliary apparatus necessary to
exercise the ports in accordance with EN 55022.

The configuration and mode of operation shall be specified in the test plan and the actual conditions,
during the tests, shall be precisely noted in the test report.

If the apparatus has a large number of similar ports or ports with many similar connections, then a
sufficient number shall be selected to simulate actual operating conditions and to ensure that all the
different types of termination are covered (e.g. 20 % of the ports or at least four ports).

The tests shall be carried out within the specified operating range for the apparatus and at its rated
supply voltage, unless otherwise indicated in the Basic Standard.

6 Applicability
The measurements in this standard shall be made on the relevant ports of the apparatus.

It may be determined from consideration of the electrical characteristics, the connection and the usage
of a particular apparatus that some of the tests are not applicable (e.g. radiated immunity of induction
motors, transformers). In such cases, the decision not to test has to be recorded in the test plan or test
report.
If not otherwise specified, the EMC tests shall be type tests.

7 Emission tests and limits
The emission tests and limits for apparatus covered by this standard are given on a port by port basis.

Measurements shall be performed in well-defined and reproducible conditions for each type of
disturbance.
The description of the test, the test methods and the test set-up are given in Basic Standards which
are referred to in Tables 1 to 6.

The contents of these Basic Standards are not repeated here, however modifications or additional
information needed for the practical application of the tests are given in this standard.

NOTE  The reference to “Basic Standard“ is intended to be limited to those parts of the standard that give the description of
the test, the test methods and the test set-up.
