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 61000-4 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 32:20 15. 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.
6 Applicability
The measurements in this document 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 and 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 document are given on a port by port basis.
Measurements shall be performed in well-defined and reproducible conditions for each type of disturbance.
The radiated emission limits defined for enclosure port in IEC 61000-6-4:2006, Table 1 shall be complied with. The description of the test, the test methods and the test set-up are given in Basic Standards which are referred to in IEC 6 1000-6-4:2006.IEC 62236-3-2 pdf download.
