Electromagnetic compatibility tests (EMC)

EMC tests consist in verifying the functionality and behaviour of the test product when subject to electromagnetic interference from the mains supply network (conducted immunity) and from the environment (radiated immunity) and verifying the interference emitted by the product into the mains supply network (conducted emissions) or emitted into the environment (radiated emissions). General objectives: to determine the product’s response to external interference; to verify that the level of interference emitted into the environment or into the mains supply network is below the limits set down in the reference standards.

The main tests include the following:

Emissions

  • Radiated emissions
  • Conducted emissions
  • Mains harmonics
  • Flicker
  • Radio disturbance power
  • Click

Immunity

  • Radiated immunity
  • Conducted immunity
  • Immunity to magnetic fields at network frequencies
  • Burst immunity
  • Surge immunity
  • Voltage sag immunity
  • Electrostatic discharge immunity
