Proposal to align the headform test with the deceleration measurement and the test of resistance to abrasion with ISO 15082:2016-11, including changes to the test details, correction of the headform calibration values, and the introduction of abrasion reference materials. The latter is combined with an abrasive-wheel qualification and a correction calculation (for plastic materials only).
The proposal also amends Figure 2a of Annex 21 to better reflect the meaning of paragraph 126.96.36.199. of Annex 21, mainly to clarify the lateral limits of any opaque obscuration in this area.
19. Referring to Figure 4-2 in ECE/TRANS/WP.29/2017/111, GRSG recalled the adoption at its last session of draft Supplement 6 to the 01 series of amendments to UN Regulation No. 43 and reconfirmed that the values in the figure were rounded to integers.
