EMC test items include electromagnetic emissions (EMI) and electromagnetic immunity (EMS) in two aspects:
I. EMI test items:
1, conduction (CE) (150kHz ~ 30MHz);
2, intermittent interference voltage (clicking sound) (150kHz, 500kHz, 1.4 MHz and 30MHz);
3, Interference power (30MHz～300MHz);
4, Harmonic current (2～40th harmonic);
5, FlickerFlicker.
Two, the test items of the EMS:
1, Electrostatic discharge immunity;
2, Radiated electromagnetic field ( 80MHz ~ 1000 MHz) immunity;
3, electrical fast transient/pulse group immunity;
4, surge (lightning strike) immunity;
5, injected current (150kHz ~ 230MHz) immunity;
6, voltage dips and short-term interruptions immunity.
