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.

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.

16. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2016/21 adapting the requirements for plastic panes, other than windscreens, to those for plastic pane windscreens including amendments to rigid plastic panes, flexible plastic panes and rigid plastic multiple-glazed units. The expert from OICA presented GRSG-111-11, improving the proposed text. GRSG supported the proposal in general, but agreed on the need to review the definition of different types of glazing, especially its classification according to principal and secondary characteristics. The expert from CLEPA proposed to amend figure 2a of Annex 18 to clarify the lateral limits of the area with any opaque obscuration. GRSG noted a number of concerns and agreed to avoid a further reduction of this area.

17. Following the discussion, GRSG adopted ECE/TRANS/WP.29/GRSG/2016/21 as reproduced in Annex II to the session report. The secretariat was requested to submit it to WP.29 and AC.1 for consideration at their March 2017 sessions, as draft Supplement 5 to the 01 series of amendments to UN Regulation No. 43.

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.
