IWG on Electromagnetic Compatibility
The IWG-EMC presents a status report to GRE-90, outlining proposed amendments to UN Regulation No. 10 for robust electromagnetic immunity testing in vehicles. The report covers topics such as extending immunity test frequency range, introducing reverberation chamber testing, defining operating conditions for vehicle systems, and new emission limits for electric vehicles.

Informal document GRE-90-33 90thGRE, 29 April - 03 May 2024 Submitted by the experts of IWG EMC Agenda item 8 IWG on Electromagnetic Compatibility (IWG EMC) Status report to GRE-90 April / May 2023
IWG EMC - Status Report Proposal for a new 07 series of amendments to UN Regulation No. 10: The frequency range of electromagnetic immunity test was extended to 6 GHz in order to ensure robustness regarding state-of-the-art mobile services (e.g. mobile phone standards and wireless networks, 4G, 5G, Wi-Fi). The reverberation chamber for ESA electromagnetic immunity test was introduced. This test method is a state-of-the-art immunity test method. The minimum number of steady state operating conditions of vehicle propulsion systems have to be considered in the test plan. This is necessary because the default test conditions may not trigger all intended operating modes. Definitions regarding automated driving systems (ADS), Acoustic Vehicle Alerting System (AVAS), Accident Emergency Call Systems (AECS) were introduced as well as additional operating conditions and failure criteria have been defined for those systems. New flow charts have been developed for each concerned annex to clarify which charge mode must be conducted with which cable. New alternative test methods have been created for longer, wider or higher vehicles with the aim to have a harmonized testing procedure of these vehicles. 2
IWG EMC - Status Report Road map for a new 08 series of amendments to UN Regulation No. 10: 2024 2025 / 26 2026 / 27 The working group develops new topics and regulatory objectives Discussions based on technical documents Drafting a working document for the 08 series of amendments 3
IWG EMC - Status Report Topics for a new 08 series of amendments to UN Regulation No. 10: New Emission limits for electric vehicles in charging mode technologies on charging modality in the vehicle Whole vehicle approval based on ESAs only Peak detector as method of measurement AECS during immunity test Requirements for bi- directional charging Reverberation chamber for vehicle immunity test Normal conditions of use (2ndphase) ADS suitability (screening of the Regulation) Better definition of current not conductive charging mode Investigate on replacement of pulse 4 reference Off-board receivers below 30 MHz Electrostatic discharge Virtual Testing 4
IWG EMC - Status Report Future planning and outlook: The working group is continuing its work with the aim to develop the 8th series of amendments IWG-EMC-45: 6 September 2024. Online IWG-EMC-46: 28 November 2024. Bonn, Germany 5
