Electromagnetic Compatibility (EMC) Tests

The emc tests consist in the correct function and behavior of the product subjected to the test in its electromagnetic environment verifying the requirements of both irradiated and conducted Emission and Immunity.

Especially for the automotive industry, IMQ Group carries out:

  • Test of immunity to radiated disturbances and conducted for the purposes for the vehicle direct control, the driver, the occupants and other road user protection as well as any disturbance that can confuse the drivers or other road users
  • Control of unwanted emissions, radiated and conducted, to protect the intended use of electric or electronics devices in the vehicle and the one near or close and the control of the disturbances emitted by accessories that can be installed on the vehicle afterwards
  • Additional requirement for vehicles and their components equipped with charging system with electricity regarding the control of emission and immunity relatively to the connection between the vehicle and the power grid.

 

The main tests are:

  • Regulation UNECE R10

Uniform provisions concerning the approval of vehicles and components regarding electromagnetic compatibility
Relatively to transients and voltage drops coupled on battery and signal lines

  • International standards and individual specification of OEM

Relatively to the normal and irregular functioning and relevant test method bodies (ISO, SAE)

 

Emissions

  • Radiated emissions (in semi-anechoic chamber 10 meters)


In addition for electric vehicles:

  • Conducted emissions
  • Network harmonics
  • Flicker


Immunity

  • Immunity radiated


In addition, for electric vehicles:

  • Conducted immunity
  • Immunity to fast electrical transients (BURST)
  • Immunity to SURGE
  • Immunity to network holes
  • Immunity to electrostatic discharge
