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.

15. The expert from Hungary presented ECE/TRANS/WP.29/GRSG/2015/22 on clarifying the technical requirements of the abrasion test machine. The expert from Poland suggested replacing figure 4 in Annex 3 with a diagram including dimensions (GRSG-111-05). The expert from Germany informed GRSG that the corresponding ISO standard would be published soon. He offered to update the document to fully align the provisions of the Regulation with those of the ISO standard. GRSG welcomed that offer and agreed to defer the adoption of the amendments to UN Regulation No. 43 to its next session in April 2017 awaiting the submission of a revised official document by Germany.

21. Referring to the discussion at the previous session of GRSG, the expert from Hungary introduced ECE/TRANS/WP.29/GRSG/2015/22 clarifying the requirements on the abrasion test machine. The experts from Germany informed GRSG about the status of work in ISO and announced that the corresponding ISO standard was in the process of being finalized and would hopefully be published by the end of the year. GRSG agreed to resume consideration of ECE/TRANS/WP.29/GRSG/2015/22 at its next session in April 2016.

20. The expert from Hungary presented GRSG-108-15 proposing to clarify the requirements on the abrasion test machine. The experts from France and CLEPA preferred to wait until the forthcoming publication of the corresponding ISO standard. GRSG invited the secretariat to distribute GRSG-108-15 with an official symbol, for further consideration at the next GRSG session.
