13. The expert from the Republic of Korea introduced GRSG-107-06, proposing an amendment to the methodology of the 227g ball drop test for toughened glass that would cope with defects of panoramic sunroofs. The experts from CLEPA and OICA provided (GRSG-107-22) comments to the national defect investigation by Korea and the proposed amendments. The expert from the Republic of Korea reiterated his intention (GRSG-106-10) to draft a parallel amendment to UN GTR No. 6 (see para. 41 below). However, he suggested that the development of amendments on both UN Regulation and the UN GTR No. 6 should be carried out by an IWG. Finally, GRSG agreed to seek consent from WP.29 and from the Executive Committee of the 1998 Agreement (AC.3) at their November 2015 sessions to establish the above-mentioned IWG.

71. Mr. Sokchang Kwon, Director General of the Motor Vehicles Policy Division of the Ministry of Land, Transportation and Maritime Affairs of the Republic of Korea gave a presentation on the results of their national defect investigations on panoramic sunroofs (WP.29-162-15). The Chair of GRSG suggested that this topic be investigated further by GRSG experts to determine whether it is necessary to adjust the relevant UN Regulation No. 43 and UN GTR No. 6 on glazing. Thus, he invited the representative of the Republic of Korea to share these findings with GRSG experts during the forthcoming session in May 2014. The representative of the Republic of Korea (Korea Automobile Testing and Research Institute (KATRI)) introduced WP.29-162-22 showing the detailed results of their investigations on safety issues with panoramic sunroofs. The representative of Japan agreed with the suggestion by the Chair of GRSG. Finally, the World Forum requested GRSG to discuss this issue at its forthcoming session in April 2014.

23. Referring to the discussion at the March 2014 session of WP.29 (GRSG-106-04), the expert from the Republic of Korea gave a presentation on the result of a national investigation on defects of panoramic sunroofs (GRSG-106-21). In this respect, he proposed an amendment to Global Technical Regulation (GTR) No. 6 on glazing (GRSG-106-10). GRSG noted a number of comments and concerns that the amendments to the drop test were not appropriate. The experts from Canada and Germany were of the opinion that further amendments to the GTR were necessary. Following the discussion, GRSG agreed to keep GRSG-106-10 on the agenda and to resume consideration of this subject at its next session. The Chair invited all experts to send, in the meantime, their comments to the expert from the Republic of Korea (e-mail: katrietf@ts2020.kr). He also invited the experts from Germany and the Republic of Korea to jointly prepare a concrete proposal.

12. The expert from Germany, Chair of the informal working group (IWG) on Plastic Glazing, introduced GRSG-107-12 with the justification for the proposed amendments to ECE/TRANS/WP.29/GRSG/2014/23, which aims to introduce new provisions for plastic windscreens and laminated plastic panes other than windscreens. GRSG adopted the proposal as amended by Annex II of this report. The secretariat was requested to submit ECE/TRANS/WP.29/GRSG/2014/23 to the March 2015 sessions of WP.29 and AC.1 as draft Supplement 4 to the 01 series of amendments to UN Regulation No. 43. GRSG considered and adopted GRSG-107-16, as reproduced below. The secretariat was requested to submit it to the March 2015 sessions of WP.29 and AC.1 as draft Corrigendum 5 to Revision 3 to the UN Regulation.

Paragraph 5.3.1., amend to read:

14. The expert from Hungary introduced GRSG-107-21, aimed at allowing the use of thick glass panes for multiple glazed units. GRSG agreed to resume discussion on this issue at its May 2015 session and requested the secretariat to distribute GRSG-107-21 with an official symbol.

19. The expert from Hungary proposed an amendment to the UN Regulation allowing the use of thick glass panes for multiple glazed units (ECE/TRANS/WP.29/GRSG/2015/4). GRSG noted some comments. The document did not receive the full support of GRSG. It was agreed to keep ECE/TRANS/WP.29/GRSG/2015/4 on the agenda and to have a final review of the proposal at the next session of GRSG.

13. The expert from the Republic of Korea introduced GRSG-107-06, proposing an amendment to the methodology of the 227g ball drop test for toughened glass that would cope with defects of panoramic sunroofs.

15. GRSG noted GRSG-107-24, tabled by the expert from CLEPA, proposing an excluded area from the main vision zone to allow the application of safety systems (e.g. rain-light sensors, collision warning systems) for vehicle category other than M1. GRSG agreed to resume consideration on this proposal at its May 2015 session and requested the secretariat to distribute GRSG-107-24 with an official symbol.

18. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2015/3 proposing to define a reduced vision zone I for vehicles of categories M and N other than M1. GRSG noted a number of study reservations on the proposal with respect to the impact of the proposed provisions for some categories of vehicles. The Chair invited all experts to send their comments to the expert from CLEPA and to resume consideration of this subject at the next GRSG session on the basis of a revised document by CLEPA.

Paragraph 5.3.1., amend to read:

16. The expert from Germany, chairing the Informal Group on Plastic Glazing (IGPG), reported on the good work progress made by the group during its eighth and ninth meetings (Paris, 27-29 November 2013; Berlin, 25-26 March 2014) (GRSG-106-13). On behalf of IGPG, he introduced GRSG-106-16 proposing new provisions on plastic glazing for windscreens and laminated plastic panes other than windscreens. GRSG noted some comments and agreed to resume consideration of this subject at its next session. The secretariat was requested to distribute GRSG-106-16 with an official symbol.

59. The representative of AGC Glass Europe expressed his concern on the number of test cycles for plastic glazing in item 4.8.1, Regulation No. 43, and the standard deviation of the measured delta haze. He proposed that GRSG extend the mandate of the IWG on Plastic Glazing to further consider these issues. The representative of OICA expressed his view that the amendments had thoroughly been considered by the IWG. The Chair of GRSG offered to revisit, at the forthcoming session of GRSG the concerns raised by AGC Glass Europe on Regulation No. 43 and, if necessary, to extend the mandate of the IWG. The representative of Germany endorsed the proposed procedure.
