ISED and FCC KDB Procedures

Question: When does Canada permit the use of FCC KDB procedures to demonstrate compliance with ISED standards?

Answer: ISED may accept alternate procedures found within the FCC knowledge database (KDB) when no other measurement procedures or international standards are appropriate.

ISED maintains a current list of their accepted FCC KDBs for EMC/RF and RF exposure-related procedures under the headings at the links below. On these pages ISED also includes expanded ISED reference standards, procedures and other documents.

  • EMC/RF – List of Alternate RF Measurement Procedures Accepted by Innovation, Science and Economic Development Canada at

  • RF Exposure – List of Federal Communications Commission (FCC) KDB procedures for SAR measurement accepted by Innovation Science and Economic Development (ISED) at

Any FCC KDB procedure can easily be accessed from the FCC site using the KDB’s number and the KDB Publication Number Search tool at

Some KDB guidance requires an official KDB inquiry submission with details about the device so the FCC can determine if the test methods and/or procedures are acceptable based on the specific circumstances.

ISED also requires an inquiry be submitted online using its General Inquiry form; Select “Directorate of Regulatory Standards,” then from the dropdown box select “(KDB) FCC KDB procedures accepted by ISED”. Include a copy of the FCC KDB inquiry submission. ISED will make its own determination.
