Electromagnetic compatibility (EMC) is divided into electromagnetic interference (EMI) and electromagnetic tolerance (EMS). All electronic products must comply with the general regulations of electromagnetic compatibility.

Electromagnetic compatibility issues are constantly being introduced by high-tech technologies in electronics, motors, information, communications, and other products. In addition to user requirements for communication quality, they are also actively regulated by relevant governments in various countries to control, which also highlights electromagnetic compatibility. The importance and urgency of related issues. For example, Europe has stepped up post-market inspections of imported products, resulting in many customs clearances.

    EMC: (Electromagnetic compatibility)
    EMI: (Electromagnetic interference) electromagnetic interference
    EMS: (Electromagnetic Susceptibility) electromagnetic sensitivity
    RE: (Radiated emission) radiation harassment (commonly known as: electromagnetic radiation, radiated emission)
    CE: (Conducted emission) Conducted harassment (commonly known as: conducted emission)
    CS: (Conducted Susceptibility) Conducted disturbance immunity
    RS: (Radiated Susceptibility) RF electromagnetic field radiation immunity
    ESD: (Electrostatic discharge)
    EFT / Burst: (Electrical fast transient burst) Electrical fast transient burst
    RFI: (Radio Frequency Interference) radio frequency interference
    ISM: (Industrial Scientific Medical) RF equipment for industrial, scientific and medical use
