The basic definition of EMC (electro magnetic compatibility) is:

    The ability of a device or system to work normally in its electromagnetic environment and not produce unbearable electromagnetic disturbance to anything in the environment. The so-called electromagnetic disturbance refers to the performance degradation of equipment or system caused by electromagnetic disturbance.
It contains two meanings:

EMI (electro magnetic interference) electromagnetic disturbance. Refers to the electromagnetic disturbance caused by the equipment itself to the environment during work

EMS (electro magnetic susceptibility) electromagnetic anti-interference. Refers to the equipment has a certain resistance to electromagnetic interference in the electromagnetic environment.

EMC test items:

EMI electromagnetic interference: RE (radiated emission) CE (conducted emission) Harmonics (harmonic current) Flicker (flicker)

EMS electromagnetic anti-jamming: ESD (electrostatic immunity) RS (radiation immunity) EFT (electric fast and variable pulse group) Surge (surge immunity) CS (conducted immunity) PMS (power frequency magnetic field immunity) ) Dips (voltage drop)

To verify the electromagnetic compatibility of the product is EMC certification.
