Formal proposal as generally agreed during the 56th GRSP session to revise the procedure for determining the bumper test area under the pedestrian safety regulation. This proposal corrects shortcomings in the current definitions which could lead to a narrower test area than intended (leading to less effective pedestrian protection). This proposal includes a “bumper beam” determination method. The proposed changes also require the form of a new series of amendments (rather than a Supplement) and proposes a transition date of 1 September 2019 (rather than the previous 2017).
The proposal also includes a September 2017 transition date in the event that the GRSP determines that the proposal should be treated as a new series of amendments rather than as a Supplement.
6. The expert from EC introduced GRSP-57-15-Rev.1, superseding ECE/TRANS/WP.29/GRSP/2015/2, and proposing the introduction of the definition of rigid bumper beam in the test area in addition to the proposed bumper test method with the flexible pedestrian legform impactor (FlexPLI). The expert from OICA introduced GRSP-57-12, explaining that the new definition of the test area leads to test bumper surfaces at an angle greater than the justified 30°. He added that this might result in occurrence of total and relative rotation of the leg as well as sliding along the surface and produce non-repeatable data. The expert from the United States of America requested a study reservation on this proposal based on the above concern regarding the test tool’s repeatability at an impact angle of 30 degrees or higher. She announced that results of this research would be available at the December 2015 session of GRSP. The expert from Japan proposed to share data from his country to be included in the cost benefit analysis. GRSP agreed to resume discussion on this subject and on the pending issues of the proposal of amendments to the UN GTR (ECE/TRANS/WP.29/GRSP/2014/15, ECE/TRANS/WP.29/GRSP/2014/16 and ECE/TRANS/WP.29/GRSP/2015/2) at its December 2015 session.
28. Referring to the decision held under agenda item 3(a) (see para. 6.), the expert from EC introduced GRSP-57-16-Rev.1 (superseding ECE/TRANS/WP.29/GRSP/2015/8, GRSP-57-12 and GRSP-57-13), introducing the new bumper test method and the definition of bumper beam and meeting the needs expressed by the expert from OICA at the December 2014 session of GRSP. GRSP adopted ECE/TRANS/WP.29/GRSP/2015/8, as amended by Annex IV (including GRSP-57-16-Rev.1) to this report. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration and vote at their November 2015 sessions, as draft 02 series of amendments to UN Regulation No. 127.
32. Referring to the decision held under agenda item 3(a) (see paragraphs 8. and 9.), GRSP endorsed in principle GRSP-56-41 (superseding ECE/TRANS/WP.29/GRSP/2014/31, ECE/TRANS/WP.29/GRSP/2014/32 and GRSP-56-40), introducing the new bumper test method and the definition of bumper beam. GRSP agreed to resume discussion at its May 2015 session to define proper transitional provisions and decide whether to adopt the proposal either as a new series of amendments or as a supplement. Finally, the secretariat was requested to distribute GRSP-56-41 with an official symbol at the next session of GRSP.
