IEC 62236-3-2-2018 pdf free download.Railway applications – Electromagnetic compatibility – Part 3-2: Rolling stock – Apparatus.
The application of tests depends on the particular apparatus, its configuration, its ports, its technology and its operating conditions.
This document 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 document 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 document does not apply to transient emissions when starting or stopping the apparatus.
The objective of this document 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 document 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.
Test requirements are specified for each port considered.
These specific provisions are used in conjunction with the general provisions in IEC 62236-1.

3 Terms, definitions and abbreviated terms
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
4 Performance criteria
The variety and the diversity of the apparatus within the scope of this document 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 IEC 62236-1:2018.
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 disturbance as appropriate in the frequency band being investigated consistent with normal applications. The conditions during testing shall be defined in a test plan (see basic standard of IEC 6 1000-4 series).
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 e.g. with CISPR 32:201 5, Clause 6.
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 nominal supply voltage, unless otherwise indicated.IEC 62236-3-2 pdf free download.
