9. The expert from the Republic of Korea, on behalf of the Chair of the IWG on Deployable Pedestrian Protection Systems (DPPS) informed GRSP about the work progress of the IWG. He explained that the group had its fourth meeting in Paris (12-14 March 2019) and that there were some controversial issues remaining such as a verification impactor which was used for testing the ability of the system to determine the most difficult to detect pedestrian within the appropriate pedestrian stature range. Moreover, he also mentioned that the defining of the head impact test area in case of a deployable pedestrian protection system remained an issue. Moreover, he noted that were few contracting parties attending IWG meetings regularly and encouraged broader participation. He also invited experts of concerned parties to have a web-meeting to resolve the above issues before the next meeting, scheduled in September in London. GRSP agreed to resume consideration on this agenda item at its December 2019 session.
