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 2.4.2.2. of Annex 21, mainly to clarify the lateral limits of any opaque obscuration in this area.
11. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2017/6 to fully align (a) the provisions for the headform test with deceleration measurement and (b) the test of resistance to abrasion with those of the corresponding standard ISO 15082:2016-11. He added that the main amendments according to this standard were the addition or modification of important test details, the correction of the headform calibration values and the introduction of abrasion reference materials; the latter combined with an abrasive-wheel qualification and a correction calculation (for plastic materials only). GRSG welcomed the proposal and noted some minor editorial corrections. Following the discussion, GRSG adopted ECE/TRANS/WP.29/GRSG/2017/6 and requested the secretariat to submit it to WP.29 and AC.1 as draft Supplement 6 to the 01 series of amendments to UN Regulation No. 43 for consideration at their November 2017 sessions.
12. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2017/8, proposing to clarify in Figure 2a of Annex 21 the lateral limits of any opaque obscuration. GRSG noted general support and adopted the proposal. The secretariat was requested to submit it to WP.29 and AC.1 as part (see para. 11 above) of draft Supplement 6 to the 01 series of amendments to UN Regulation No. 43 for consideration at their November 2017 sessions.
