IEC TC106 Meeting Update

IEC TC106 Meeting Update

Technical experts of IEC TC106 and ICES TC34 continued their rapid pace on electromagnetic exposure assessment standardization. Following the completion of two significant Specific Absorption Rate (SAR) standards, this meeting focused on preparation for the realization of 5G and IoT (Internet of Things) communication technologies. Robust and high-quality exposure assessment is key to providing public confidence in the safety of these systems.

IEC TC106 and ICES TC34 met jointly to draft electromagnetic exposure assessment standards in Paris from June 4‒7, 2018. The meeting was graciously hosted by French regulatory agency ANFR (Agence Nationale des Frequencies.

Joint Working Groups, established by IEC and IEEE last year, have the mandate to complete two standards for exposure assessment of millimeter wave devices by 2020, when 5G rollout is expected. At millimeter wave frequencies (10‒300 GHz), power density is the basic restriction for human exposure to electromagnetic fields. This is a new frontier in exposure assessment, and many questions are being asked about the best way to assess power density when a person is in the near field of the radiating device. The IT'IS Foundation is among a group of leading researchers working on this issue. The committee drafts of both standards are scheduled to be completed at our next meeting in September in Stockholm.

At the Paris meeting it was decided to use a performance-based approach for the 5G measurement standard. This open approach allows equipment makers to develop innovative measurement techniques. A strong emphasis on validation and verification is applied to ensure high confidence in the results.

This was the inaugural meeting of IEEE Project Team 1528.7 to develop a guide for IoT exposure assessment. The goal is to clarify testing requirements and procedures for a wide range of IoT use cases. Challenges being discussed include how to evaluate exposure from multiple IoT devices and devices operating simultaneously at different frequency bands.

Within the last 12 months, IEC TC106 and ICES TC34 completed several exposure assessment standards:

  • IEC TR 62905: technical report (TR) for exposure evaluation of wireless power transfer (WPT) devices, such as electric vehicle chargers and wireless mobile phone charging pads
  • IEC PAS 63151: publicly available specification (PAS) for SAR measurement of wireless devices using vector measurement-based systems
  • IEC/IEEE 62704-1: general requirements using FDTD for numerical assessments of SAR
  • IEC/IEEE 62704-2: specific requirements using FDTD for SAR caliculations of vehicle-mounted antennas
  • IEC/IEEE 62704-3: specific requirements using FDTD for SAR calculations of mobile phones

This pace shows no sign of slowing down. The group celebrated the completion of two draft standards that are being prepared for voting:

  • IEC/IEEE 62209-1528: SAR measurement standard for hand-held and body-worn wireless devices
  • IEC 62209-3: SAR measurement standard using vector measurement-based systems

Meeting of IEC TC106 WG9 and New Project Team for WPT Compliance Hosted by IT’IS April 10–11

Z43 was the site of the latest meeting of the International Electrotechnical Commission (IEC) Technical Committee (TC) 106 Working Group (WG) 9, held April 10 – 11 April 2018, convened by Dr. Teruo Onishi and hosted by the IT’IS Foundation, with sponsoring by Schmid & Partner Engineering (SPEAG). The 2-day meeting included the inauguration of the new Project Team (PT) 63184, established after the October 2017 plenary meeting of TC106 in Melbourne, Australia to formulate the basic standard for exposure to wireless power transfer (WPT) systems over the frequency range 1 kHz – 10 MHz.

Surprising Outcome of the Peer Review of the Draft Technical Reports of National Toxicology Program’s Radiofrequency Radiation Studies in Rodents

On March 26 – 28, 2018, the National Institute of Environmental Health Sciences (NIEHS) conducted an intense peer review of draft technical reports of the results of the National Toxicology Program (NTP) study of exposure of rodents to radiofrequency radiation. The public review process was attended by members of the public and was broadcast live from the NIEHS campus in Research Triangle Park, North Carolina, USA. Scientists responsible for the studies made presentations to a panel of external experts on the methodologies used in the studies and the evaluation of the results and answered questions.
