Product Testing and Certification

Electromagnetic Compatibility (EMC)

EMC testing laboratory is accredited according to SIST EN ISO/IEC 17025 and is a recognized testing laboratory (CBTL) in the IECEE’s international certification system (CB system). SIQ is accredited by Slovenian Accreditation (SA), a member of the international organisation for accreditation bodies (ILAC).

Furthermore, SIQ is recognized as a notified body with identification number 1304 in the EU for EMC Directive 2014/30/EU and Radio Equipment Directive 2014/53/EU.

We carry out the following EMC, radio and EMF/MPE tests according to relevant harmonized European standards and international standards:

  • Emission testing (EN, IEC, BS, ISO, FCC, IC, ICES, VCCI)
  • Immunity testing (EN, IEC, BS, ISO)
  • Harmonics and flicker for public grid (EN, IEC, BS)
  • EMF testing (EN, IEC, FCC, IC)
  • EMC testing and electrical tests for vehicles and vehicle components (EN, IEC, ISO)
  • Radio spectrum testing (EN, FCC, IC)
