OICA comments and concerns regarding the generally accepted proposal for the definition of the bumper test area for use with the Flex-PLI lower leg impactor. The document raises issues concerning limitations of the test procedure and notes that the new requirements would have a significant impact on bumper design such that the transitional period for implementation should be 2019 to allow for a full vehicle development cycle.
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.
