Electromagnetic Compatibility (EMC)

Electromagnetic compatibility is the ability of a unit of equipment to operate correctly in its electromagnetic environment without causing excessive electromagnetic interference with any other equipment in that environment. In general, when establishing electromagnetic compatibility, we are talking about determining:

  • Electromagnetic emissions, i.e. electromagnetic interference caused by a device, equipment, or system due to its operation;
  • Electromagnetic resistance, i.e. the ability of a device, unit of a device, or a system to function unimpaired in the presence of electromagnetic interference.


SIQ is a Notified Body for the Electromagnetic Compatibility Directive 2014/30/EU

We are professional, accurate, and responsive in meeting your requirements for electromagnetic compatibility testing and certification. Our measurements, test reports, and certificates assure EMC compatibility of your product in all important markets. We provide our professional assistance already at the stage of development when we can carry out partial critical tests of individual devices. Our experts follow development trends in the field of electromagnetic compatibility of devices, and our laboratory has a modern equipment.
