4. GRSP considered the issue of UN GTR No. 9 Amendment 3 (Headform test) but concluded that since there was no new information made available to the experts, it was not possible to restart the discussions on Amendment 3. GRSP recalled the recommendation in the report of WP.29 (see ECE/TRANS/WP.29/1157, paragraphs 148 to 150) that in the interim, GRSP conclude its discussions on Amendment 4 on the Deployable Pedestrian Protection Systems (DPPS), which then be re-numbered as the new Amendment 3. The experts had agreed that when new information becomes available, experts from Germany, Netherlands, United States, other contracting parties and interested stakeholders would seek to reengage the discussion on the headform test as the new Amendment 4.

5. Referring to the AC.3 decision at its March 2020 session (see ECE/TRANS/WP.29/1151, para. 158), GRSP reiterated its intention to finalise the work on harmonizing UN GTR No. 9 with UN Regulation No. 127, which already incorporates the proposed Amendment 3 to the UN GTR for the headform test (ECE/TRANS/WP.29/GRSP/2014/5 as amended by GRSP-67-13). However, the expert from the United States of America suggested that, due to the postponement of this current GRSP session from May to July, AC.3 had not received the results of the discussions and should first be informed of the process at its next session in November 2020 before vote on the proposed Amendment 3 at its March 2021 session.

Therefore, GRSP recommended: (a) Amendment 3 to UN GTR No. 9 (ECE/TRANS/WP.29/GRSP/2014/5), as amended by Annex II to the session report, (b) the final progress report (ECE/TRANS/WP.29/GRSP/2012/2) as amended by Annex II to the session report and (c) the authorization to develop the work (ECE/TRANS/WP.29/AC.3/31), for consideration and vote at the March 2021 sessions of WP.29 and AC.3.

6. The expert from the United States of America announced that the National Highway Traffic Safety Administration (NHTSA) had agreed to accept Injury Assessment Reference Values (IARVs) to move Phase 2 forward and to incorporate the flexible pedestrian legform impactor (FlexPLI). He added that IARVs could change as a result of cost benefits analysis conducted during the adoption process of the GTR when transposed into the national legislation of Contracting Parties. Accordingly, he proposed GRSP-60-17 to amend Part A of the statement of technical rationale and to justify of ECE/TRANS/WP.29/GRSP/2014/15. Moreover, he reported that his administration had not yet completed its cost-benefit analysis, but the United States of America New Car Assessment Programme was already using the FlexPLI and the new improved bumper test proposed by the Task Force on Bumper Test Area (TF-BTA) (ECE/TRANS/WP.29/GRSP/2015/2). He concluded that for the new proposed requirements for the head form tests (ECE/TRANS/WP.29/GRSP/2014/5) some more analysis would be needed.

7. Referring to the statement of the expert from the United States of America, GRSP noted that at its May 2017 session it would likely be in the position to recommend the Phase 2 of the GTR as a full package: ECE/TRANS/WP.29/GRSP/2014/15, ECE/TRANS/WP.29/GRSP/2015/2 and GRSP-60-17. The expert from the United States of America announced that a meeting of the IWG in Washington, D.C. would be scheduled at the beginning of 2017. Thus, GRSP recommended for its May 2017 session:

1. IWG to provide a final report of the development of Phase 2 (update of ECE/TRANS/WP.29/GRSP/2014/16, fifth status report of the IWG),
2. IWG to finalise the analysis because the new headform test were incorporated as well (ECE/TRANS/WP.29/GRSP/2014/5) and
3. the secretariat to distribute GRSP-60-17 with an official symbol.

9. GRSP agreed to dissolve the activities to update Phase 1 of the GTR and to focus efforts on Phase 2 and on future amendments (e.g. ECE/TRANS/WP.29/GRSP/2014/5, see para. 6). Thus, it was agreed to remove ECE/TRANS/WP.29/GRSP/2014/2 from the agenda and to keep ECE/TRANS/WP.29/GRSP/2012/2 (progress report) which would be updated, once that the activity on the head form tests would be finalized (see agenda item 4(a), para. 6).

6. The Chair of GRSP, on behalf the United States of America reiterated the experts that NHTSA’s request for a delay of the proposal at this time as NHTSA is going thru its adoption process of phase 1 (ECE/TRANS/WP.29/GRSP/2014/5). He concluded that he would inform GRSP at its December 2017 session about the plan of an NPRM on this subject.

6. The expert from the United States of America informed GRSP that NHTSA had initiated a Notice of the Proposed Rulemaking for establishing the current requirements for head form tests, as proposed by GRSP. [but that this notice] had been on hold due to other priorities at NHTSA. The expert from EC recommended a fast-tracking process to ensure harmonization.

9. The expert from the EC introduced GRSP-54-07-Rev.1 to clarify provisions of the headform tests and superseding ECE/TRANS/WP.29/GRSP/2012/14 (including the final report ECE/TRANS/WP.29/GRSP/2012/2). The expert from the United States of America stated that, as a general issue, the proposal was not evidence-based (GRSP-54-31) and lacked data from the current method. GRSP agreed to resume discussion at its May 2014 session on the basis of more data and requested the secretariat to distribute GRSP-54-07-Rev.1 with an official symbol and to keep GRSP-54-31 as a reference.

9. The expert from OICA reiterated his intention to continue the work on harmonizing UN GTR No. 9 with UN Regulation No. 127 which had already incorporated the proposed amendments for the headform test (ECE/TRANS/WP.29/GRSP/2014/5). He suggested that at the March 2020 session of the Executive Committee of the 1998 Agreement (AC.3), the Chair of GRSP could recommend Amendment 3 (ECE/TRANS/WP.29/GRSP/2014/5) to UN GTR at its May 2020 session. Therefore, GRSP agreed to finalize discussion of this subject and to review an updated final progress report (ECE/TRANS/WP.29/GRSP/2012/2) that had been submitted by the technical sponsor.

9. Moreover, the expert from OICA gave a presentation (GRSP-55-40) on the work progress of the Task Force Bumper Test Area (TF-BTA), a subgroup of the IWG on UN GTR No. 9 – Phase 2 and proposing an amendment (GRSP-55-41) to the provisions of the bumper test.

10. GRSP agreed to resume consideration of this agenda item at its December 2014 session, awaiting the outcome of research on this issue from Contracting Parties concerned. GRSP requested the secretariat to distribute GRSP-55-41 with an official symbol at its next session. Finally, it was agreed to consider GRSP-55-24 under agenda item 17.

27. GRSP resumed consideration on the remaining issues of the proposed 01 series of amendments to UN Regulation No. 127 (ECE/TRANS/WP.29/2014/38), such as the tolerances of the flexible pedestrian legform impactor (FlexPLI). GRSP finally adopted GRSP-55-14-Rev.3 (incorporating GRSP-55-24), as reproduced in Annex V to this report. GRSP requested the secretariat to send the proposal (WP.29-163-06) to WP.29 and AC.1 for consideration and vote at their June 2014 sessions as a draft amendment to ECE/TRANS/WP.29/2014/38. GRSP also adopted GRSP-55-44, as reproduced in Annex V to this report, to introduce a parallel correction to Supplement 1 of the original version of the UN Regulation (ECE/TRANS/WP.29/2014/37). GRSP requested the secretariat to send the proposal (WP.29-163-07) to WP.29 and AC.1 for consideration and vote at their June 2014 sessions as a draft amendment to ECE/TRANS/WP.29/2014/37.

28. GRSP agreed to resume consideration at its December 2014 session of this agenda item based on a possible proposal of an Addendum to the M.R.1 to incorporate the FlexPLI.

10. The expert from the United States of America informed GRSP that the NPRM activity above-mentioned in para. 7 was in progress and would incorporate a discussion of the new proposed requirements for the head form tests (ECE/TRANS/WP.29/GRSP/2014/2 and ECE/TRANS/WP.29/GRSP/2014/5). He recommended that interested parties comment on the proposed amendments to the head form tests in the NPRM so that a globally harmonized procedure could be developed. GRSP confirmed that the proposal of amendments would concern Phases 1 and 2 of the UN GTR.

11. GRSP agreed to defer discussion on this agenda item to its next sessions awaiting the outcome of the cost/benefit analysis and the transposition process of the UN GTR Phase 1 into the legislation of the United States of America.

135. AC.3 noted that the proposal under this agenda item had been withdrawn.

143. The representatives of the United States of America requested that AC.3 agree to a deferral of the vote on this item due to its final technical evaluation of the amendment earlier this year. They explained that technical experts in the United States had identified how the proposed amendment to UN GTR No.9 on Pedestrian Safety lowers the stringency of the underlying performance requirement for head impact protection. Due to important safety considerations, the United States of America requested additional time to discuss its scientific findings with GRSP. In addition to the need to further evaluate the underlying safety protections as proposed in the amendment, the representatives of the United States of America noted that there are no fewer than three additional amendments pending or being planned, from various contracting parties. Some of which will have a direct impact on the stringency of the UN GTR. In fact, one of these amendments has the potential to improve the stringency of the testing requirements. Therefore, they questioned why WP.29 would adopt the amendment at this session which reduces the stringency of the UN GTR, only to retighten or potentially improve it shortly thereafter. The representatives of the United States of America detailed some of their expert findings and urged the group to pay closer attention to how proposed amendments to UN GTRs relate to each other, take the time to make sure all parties are confident that they are based on the best available scientific evidence available before being presented for adoption to ensure the highest possible levels of safety are attained. The representatives of the United States of America also pointed out that the requested postponement would have no effect on Contracting Parties that operate under the 1958 Agreement because the pending amendment was already incorporated into UN Regulation No. 127. Furthermore, the representatives reminded AC.3 that according to the rules and procedures of the 1998 Agreement (Paragraph 6.2.5.1.), a proposal that is found to be inadequate may be returned to the originating Working Party for revision. Finally, the United States of America representatives also reminded AC.3 that the process of international harmonization of vehicle regulations is an inclusive process, initiated through regulatory activities within the scope of the 1998 Agreement and continued with corresponding activities under the 1958 Agreement, with the aim to encompass the largest representation at the global level.

144. The representative of the European Union argued that the request for postponement on such short notice was undermining the consensus reached by experts after more than six years of discussion in GRSP, based on which the amendment was submitted to the vote in March 2021 WP29 meeting. She stressed that this created a dangerous precedent, whereby any Contracting Party, in disregard of the outcome of work that had already been finalised and validated by the experts, can delay adoption of the legislation and disrupt the procedure at any time. GR level is the one to propose and discuss technical solutions until submission of the draft text for vote. United States of America despite request to this end formulated already in 2015, did not provide any elements for discussion supporting their position, only until March 2021 AC3 session. She stressed that this is not appropriate way of proceeding. She underlined that technical explanations provided by the expert from the United States of America were already examined by GRSP at length (the United States of America had a study reservation on the proposal since 2012), were not endorsed by GRSP and therefore could not be considered at this stage as a basis for postponement by AC.3. She also added that the allegations of lowered stringency of the proposed amendment, the provisions of which are based on UN Regulation No. 127 would create a precedent affecting the credibility of the 1958 Agreement. She underlined that no Contracting Party voiced concerns with regard to the safety levels of Regulation 127, which is a mirror legislation to GTR 9 with the suggested amendment.

145. The representative from Canada proposed to delay the vote until June 2021 in order to retain the work performed so far by GRSP.

146. The expert from Germany expressed his view on the necessary urgency for reaching a solution and called on GRSP to immediately commence with appropriate activities, having in mind the short timeframe between the upcoming GRSP session in May 2021 and the next AC.3 and WP.29 sessions scheduled for June 2021.

147. Upon repeated consultations with the Committee concerning positions of AC.3 members with respect to the possible establishment of the amendment, the Chair of AC.3 concluded that the support from the Committee to reach consensus was not adequate.

148. AC.3 agreed to defer vote under this agenda item to its June 2021 session pending further discussions concerning the proposal for Amendment 3 to UN GTR No. 9 at the next session of GRSP, scheduled to take place in May 2021. AC.3 requested GRSP to give highest priority to the task and to report back to AC.3 and WP.29 with the greatest urgency on the progress towards a resolution of outstanding matters in this context. AC.3 agreed to keep this item on its agenda for the next session with the expectation to vote on the amendment.
