EMC Technical Services

We are professional, accurate, and responsive in meeting your requirements for electromagnetic compatibility testing and certification. Our measurements, test reports, and certificates assure the EMC compatibility of your product in all important markets. We provide our professional assistance at the earliest stages of development when we can perform partial, critical tests on individual devices.

SIQ is a part of the international IECEE CB EMC Scheme. In the SIQ EMC laboratory, our qualified, experienced, and skilled EMC test engineers can perform all required tests on specific equipment for EMC testing of measuring devices and laboratory equipment.

  • IEC/EN 61326-1 – Defines the EMC requirements for electrical equipment for measurement, control, and laboratory use.
  • EN 61000-3-2 – Limits for harmonic current emissions (equipment input current ≤ 16 A per phase).
  • EN 61000-3-3 – Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated current <= 16 A per phase and not subject to conditional connection.
  • EN 303 446-1 – Standard for combined and/or integrated radio and non-radio equipment (only applicable to products containing radio modules).
  • FCC testing – Testing according to 47 CFR Part 15 Subpart B to cover requirements for the US market.

CB Certification

The IECEE CB Scheme is an international system for the mutual recognition of test reports relating to the safety of electrical and electronic products. The CB certificate is a document certifying that the product meets the requirements of the relevant IEC standard.

SIQ operates within the CB Scheme as a recognised National Certification Body (NCB) and a recognised Testing Laboratory (CBTL), thus awarding CB Certificates of Conformity and associated CB Test Reports.

A manufacturer who has a CB Test Report from any of the national CB Scheme Certification Bodies can obtain a national certificate from any other CB Scheme member country.
