4 Performance criteria
A functional description and a definition of specific performance criteria, during or as a consequence of immunity testing of equipment under test (EUT), shall be provided by the manufacturer and noted in the test report. They shall be consistent with one of the following general criteria for each test as specified in Table 1 to Table 4:
a) Performance criterion A: The EUT shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the EUT is used as intended. If the performance level is not specified by the manufacturer, this may be derived from the product description and documentation and what the user may reasonably expect from the equipment if used as intended.
b) Performance criterion B: The EUT shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the EUT is used as intended. The performance level may be replaced by a permissible loss of performance. However, during the test degradation of performance is allowed but no change of actual operating state or stored data is allowed. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the equipment if used as intended.
c) Performance criterion C: Temporary loss of function is allowed during the test, provided the function is self-recoverable or can be restored by the operation of the controls.
If, as a result of the application of the tests defined in this standard, the EUT becomes dangerous or unsafe, it shall be deemed to have failed the test.
If the equipment is part of a system, or can be connected to auxiliary equipment, the equipment shall be tested while connected to the minimum representative configuration of auxiliary equipment necessary to exercise the ports. Auxiliary equipment may be simulated.
In cases where a manufacturer’s specification requires external protection devices or measures which are clearly specified in the user’s manual, the test requirements of this standard shall be applied with the external protection devices or measures in place.
If the equipment has a large number of similar ports or ports with many similar connections, a sufficient number shall be selected to simulate actual operating conditions and to ensure that all the different types of termination are covered. Justification for the selection of the tested ports shall be included in the test report.
The tests shall be carried out at one single set of parameters within the operating ranges of temperature, humidity and atmospheric pressure specified for the product and at the rated supply voltage, unless otherwise indicated in the basic standard.
6 Product documentation
If the manufacturer is using his own specification for an acceptable level of EMC performance or degradation of EMC performance during or after the testing required by this standard, this fact shall be stated in the user documentation. This specification itself shall be made available upon request.
7 Applicability
The application of tests for evaluation of immunity depends on the particular equipment, its configuration, its ports, its technology and its operating conditions.
Tests shall be applied to the relevant ports of the equipment according to Table 1 to Table 4. Tests shall only be carried out where the relevant ports exist.
It may be determined from consideration of the electrical characteristics and usage of a particular equipment that some of the tests are inappropriate and, therefore, unnecessary. In such a case, the decision and justification not to test shall be recorded in the test report.
8 Measurement uncertainty
Where guidance for the assessment of the instrumentation uncertainty of an immunity test is specified in IEC TR 61000-1-6 or in the corresponding basic standard, this should be followed.
9 Immunity test requirements
The immunity test requirements for equipment covered by this standard are given on a port by port basis and listed in Table 1 to Table 4.
Tests shall be conducted in a well-defined and reproducible manner.
The tests shall be carried out individually as single tests. The tests may be performed in any order. Identical units may be used for testing in parallel, and this information shall be recorded in the test report.IEC 61000-6-2 pdf download.
