22. The expert from OICA introduced GRSG-130-22 aimed at removing the amendments related to the temperatures proposed in ECE/TRANS/WP.29/GRSG/2025/35; he argued that he had not found any internal data justifying an increase in the temperatures allowed in the rear seats of passenger vehicles – nor data tabled at GRSG justifying such increase. As a result, he suggested adoption of the proposal without any change in the performance requirements of the UN Regulation. The expert from the Kingdom of the Netherlands, on behalf of TF on Autonomous Vehicles Regulatory Screening, introduced GRSG-130-40, clarifying that issues were not foreseen for existing vehicles, and that the research carried out by the Republic of Korea for the introduction of radiant heater provides clear guidance. GRSG experts agreed with the conclusion of the expert from the Kingdom of the Netherlands. GRSG agreed to finalize discussion on ECE/TRANS/WP.29/GRSG/2025/35 under agenda item 14(b).
