34. The expert from Germany on behalf of the IWG on Electromagnetic Compatibility of the Working Party on Lighting and Light-Signalling (GRE IWG EMC) introduced GRSG-124-01, superseding ECE/TRANS/WP.29/GRSG/2022/28, to consider a proposal for guidance on some aspects of emergency. The expert from Japan supported the option one indicated in GRSG-124-01. He explained that checking the warning alarm of the emergency call system before and after immunity test is enough to verify whether the system is working properly or not. Moreover, he stated that, if GRSG prefers option 2a or 2b, Japan unfortunately could not agree at this moment, and the necessity of the pros and cons of options 2a and 2b should be made clearer in GRE IWG EMC before discussion on this guidance. GRSG did not reach consensus, but most contracting parties supported the methodology of option 2b as a compromise. GRSG found that the most appropriate solution would be EMC tests performed at the three levels of component, system and vehicle – and that it was important to define the requirements independently from the test conditions to show compliance for type approval. GRSG agreed that the text of option 2b should be further detailed.
