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.
