Proposal from the Bumper Test Area Task Force 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 does not take into account potentially harmful hard structures such as bumper beams that may lie behind the outer contour or front fascia extending beyond the defined bumper corners as consensus within the task force could not be reached.

8. The expert from EC introduced ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30, submitted by the Task Force on Bumper Test Area (TF-BTA), a subgroup of the Informal Working Group on global technical regulation No. 9 – Phase 2, and proposing an amendment to the provisions of the bumper test. He explained that the current provisions allow the area to be narrower than intended in the provisions of the UN GTR. He added that ECE/TRANS/WP.29/GRSP/2014/17 was proposing a new method by introducing a practical determination of angle surfaces, to be tested with the FlexPLI, by using a corner gauge. Moreover, he explained that ECE/TRANS/WP.29/GRSP/2014/30 was proposing the introduction of the definition of rigid bumper beam in the test area in addition to the above-mentioned new test method. He finally informed GRSP that a test report on research conducted by EC on this issue was available. The expert from Japan gave a presentation (GRSP-56-03) to support ECE/TRANS/WP.29/GRSP/2014/17. The expert from Korea presented GRSP-56-20 supporting ECE/TRANS/WP.29/GRSP/2014/30. The expert from OICA introduced GRSP-56-30, supporting the new method as proposed by ECE/TRANS/WP.29/GRSP/2014/17, because the test is less sensitive to specific design features and it could be performed without disassembling parts. Moreover, GRSP discussed GRSP-56-38 and GRSP-56-39, superseding respectively ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30.
