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. 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).
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.
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.
