23. The expert from the Republic of Korea presented ECE/TRANS/WP.29/GRSG/2023/8 and amendment GRSG-125-15 in a live presentation at Palais des Nations on examples of “radiation warmers” to allow their use on Electric Vehicles (EV) among others. He also introduced two presentations (GRSG-125-16 and GRSG-125-17) to inform GRSG about a technical seminar held on 8 March 2023, in Frankfurt, Germany on the medical investigation of radiant warmers. He added that the technology of radiation warmers was expected to increase the energy efficiency of EV and to prevent the sharp reduction of the All Electric Range (AER). The expert from OICA introduced GRSG-125-33-Rev.4, aimed at resolving harmonization issues introduced by GRSG-125-15. He also explained that industry needed flexibility and no design restrictions, since objective pass/fail criteria did not exist for such technology. The expert from France suggested that the temperature threshold for rear passengers should be reviewed and modified in a second step. The expert from Germany echoed the suggestion of the expert from France and envisaged a new series of amendments for a second step.

24. Finally, GRSG adopted ECE/TRANS/WP.29/GRSG/2023/8 as amended by annex IV to the session report. The secretariat was requested to submit the proposal as Supplement 7 to the original version to the UN Regulation No. 122 to the November 2023 sessions of WP.29 and AC.1. Moreover, GRSG agreed to resume discussion on the need for a second step on this subject at its October 2023 session.

21. The expert from the Republic of Korea asked for guidance from the group on the need for a second step for radiant warmer. The expert from the Netherlands explained that some inconsistencies were noted in the UN Regulation on radiant warmers. He clarified, as an example, that rear seats currently allow for higher temperatures at the outlets in the rear where at the same time rear seats are likely to carry vulnerable children. GRSG agreed to resume discussion on this subject based on possible proposals at its April 2024 session.
