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.

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.
