4.1.2 It is not always possible to measure emission for every function of the apparatus or assembly of apparatus. In such cases, the most critical period of operation shall be selected under normal operating modes.
4.1.3 If the reference standards do not specify any other conditions, then the tests shall be carried out at a single set of environmental conditions within the manufacturer’s specified operating range of temperature, humidity, pressure and supply voltage.
4.1.4 Measurements shall be taken in well-defined and reproducible conditions for each test. The configuration and mode of operation during measurement shall be precisely recorded.
4.2 Radiated and conducted radio-frequency emissions
4.2.1 The tests, test methods, characteristics of the tests and test set-ups shall be as stated in CISPR 11.
4.2.2 Travelling cables or any other cables likely to be more than 5 in long shall be represented by a sample of at least 5 m long connected to the relevant port for the purpose of testing for radiative emission.
4.2.3 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.
4.2.4 Measurement shall be taken at the enclosure ports (radiative), AC. mains and machine/motor ports (conductive) of the apparatus/assembly of apparatus.
4.3 Voltage fluctuation and flicker
The tests, test methods, characteristics of the tests and test set-ups shall be as stated in IEC 61000-3-11.
4.4 Mains supply harmonics
The calculation or measurement, test methods, characteristics of the tests and test set-ups shall be as stated in IEC 61000-3-12.
The system shall have stabilized into its normal state as defined by the manufacturer before harmonic measurements are taken.
The calculation or measurement shall be done under load condition with a reference current greater than or equal to the reference current as referred to in 612.
5 Applicability of tests
5.1 The application of tests for evaluation of levels of emission depends on the type of apparatus/ assembly of apparatus, its configuration, ports, technolo’ and operating conditions.
5.2 It can be determined from consideration of the electrical characteristics and usage of a particular apparatus/assembly of apparatus, that some of the tests are inappropriate and therefore unnecessary. In such a case, the decision and justification not to test shall be recorded.
5.3 Where deviations from the test methods specified in 4.2.1 and 4A are applied, such deviations shall be justified and recorded.
For wired network ports, Class A from CISPR 32 applies.BS ISO 8102-1 pdf download.
