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.

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.

18. GRSG endorsed the Chair’s proposal to set up a task force to work on a concrete proposal aligning the French and English version of the Regulation and clarifying the definition of types and the area with any opaque obscuration. Thus, GRSG agreed to resume consideration of this subject at its next session in April 2017.
