AS IEC 61000.4.1:2017 Electromagnetic compatibility (EMC)
– IEC 61 000-4-1 9 (Test for immunity to conducted, differential mode disturbances and signalling in the frequency range 2 kHz to 150 kHz at a.c. power ports) This test is intended to demonstrate the immunity of equipment connected to a.c. mains when subjected to conducted, differential mode disturbances such as those originating from power electronics and power line communication systems (PLC).
– IEC 61 000-4-20 (Emission and immunity testing in transverse electromagnetic (TEM) waveguides)
This standard specifies equipment and test procedures for testing to radiated electromagnetic fields in TEM cells as an alternative to testing according to IEC 61 000-4-3.
– IEC 61 000-4-21 (Reverberation chamber test methods)
This standard specifies equipment and test procedures for testing to radiated electromagnetic fields in reverberation chambers as an alternative to testing according to IEC 61 000-4-3.
– IEC 61 000-4-22 (Radiated emissions and immunity measurements in fully anechoic rooms (FARs))
This standard specifies equipment and test procedures for testing to radiated electromagnetic fields in fully anechoic rooms as an alternative to testing according IEC 61 000-4-3.
– IEC 61 000-4-23 (Test methods for protective devices for HEMP and other radiated disturbances)
This standard covers testing of protective elements designed to reduce the level of radiated electromagnetic fields from HEMP and other high power transients.
– IEC 61 000-4-24 (Test methods for protective devices for HEMP conducted disturbance) This standard covers testing of voltage breakdown and voltage-limiting characteristics of high-altitude electromagnetic pulse protective devices.
– IEC 61 000-4-25 (HEMP immunity test methods for equipment and systems) This standard specifies the basic high-altitude electromagnetic pulse (HEMP) test methods and levels appropriate for radiated and conducted immunity testing. It is applicable for equipment and systems intended to survive a HEMP.
– IEC 61 000-4-27 (Unbalance, immunity test for equipment with input current not exceeding 16 A per phase)
This test may be applicable to three-phase equipment with a rated input current up to 1 6 A per phase, connected to a three-phase a.c. mains. However, this test is not applicable to equipment taking three-phase power but using it in a single-phase manner.
– IEC 61 000-4-28 (Variation of power frequency, immunity test for equipment with input current not exceeding 16 A per phase)
In general, the test for variation of the power frequency is not applicable. However, it may apply to equipment intended to be installed at locations where the power frequency has large variations (for example equipment connected to an emergency power supply).
