Electromagnetic Compatibility (EMC) Testing

What is Electromagnetic Compatibility (EMC) Testing?

EMC testing verifies whether military or automotive components operate properly within the electromagnetic environment of a system and whether they cause or are affected by interference with other electronic systems. Through various tests such as conducted/radiated emissions, immunity, and electrical performance, EMC compliance is ensured. This helps prevent performance degradation or damage between electronic devices (components), while improving safety and reliability in electromagnetic environments.

Test Items

  • Electromagnetic Interference (EMI) Test

    • Purpose : To measure electromagnetic emissions generated during equipment operation and confirm that they are below specified limits to prevent interference with other electronic devices.
    • Test Items : Radiated Emission (RE), Conducted Emission (CE)

  • Electromagnetic Susceptibility/Immunity (EMS) Test

    • Purpose : To verify that electronic equipment continues to operate normally even when exposed to external electromagnetic interference.
    • Test Items : Radiated Immunity (RS/RI), Conducted Immunity (CS/BCI)

  • Electrical Characteristics Test

    • Purpose : To evaluate the electrical performance and durability of components under various battery-related stress conditions such as voltage fluctuation, interruption, and short-circuit.
    • Test Items : Overvoltage, Power Voltage Variation, Voltage Interruption, Short-circuit, Intermittent Operation, Transient Immunity (TI), Transient Emission (TE)
