22. The expert from Italy, Chair of IWG on Protective Helmets (IWG-PH), informed GRSP about the work progress of the group which had last convened on 13 May 2019 in Geneva. He explained that IWG had examined and, in principle, agreed on ECE/TRANS/WP.29/GRSP/2019/11. He underlined that the proposal would be further updated by IWG, according to the results of ongoing research and that the main goal of the proposal was rotational acceleration requirements. The expert from Germany stated that the proposal should be considered as a two-step approach. He clarified that rotational acceleration needed keener research. He added that the proposed, agreed amendment was a compromise stemming from the existing requirements of the UN Regulation. He stated that the draft amendment should be revised within the next two years to incorporate research results. The experts from France and the Netherlands agreed with the expert from Germany and clarified that research should be kept ongoing to incorporate better solutions in the future.

23. GRSP agreed to resume discussion on this subject at its December 2019 session on the basis of a revised version of ECE/TRANS/WP.29/GRSP/2019/11, submitted by IWG.
