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.

7. Referring to his presentation (GRSP-56-21) given during the December 2014 session of GRSP, the expert from the Republic of Korea reiterated the issue of the lack of provisions concerning tests of active devices to further improve vehicle performances. The expert from OICA informed GRSP that recommendations and guidelines addressing technical services for testing active safety bonnets was provided by a paper (INF GR/PS/141 Rev.1) of the former IWG.

8. GRSP agreed to resume discussion on this topic at its December 2015 session and invited the experts of Korea and OICA to continue their exchange of views on a possible draft amendment to the UN GTR and on a draft request for authorization by AC.3 to develop it. Finally, GRSP agreed to seek the endorsement of WP.29 and AC.3 to their June 2015 sessions to extend the mandate of the IWG until December 2016.
