This agenda item relates to UN R43 Safety Glazing.

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.

17. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2014/8 proposing an amendment to UN Regulation No. 43 to cope with the difficulties of technical services located at high altitudes when fulfilling the barometric pressure conditions required for the impact test. The expert from CLEPA preferred to adopt an amendment (ECE/TRANS/WP.29/GRSG/2014/9) to the boiling water test procedure. GRSG adopted ECE/TRANS/WP.29/GRSG/2014/9, as reproduced below, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions, as draft Supplement 3 to the 01 series of amendments to UN Regulation No. 43.

Annex 3, paragraph 5.1., amend to read:
“5.1. Procedure
Heat to 100 °C +0 °C / -2 °C three samples or three square test pieces …… specified period of time, care being taken to avoid undue thermal shock. The test shall be carried out in an oven if the boiling water temperature is outside the specified tolerance. If samples are cut from windscreens, one edge of each such sample shall be part of an edge of the windscreen.”

18. The expert from OICA introduced ECE/TRANS/WP.29/GRSG/2014/14 proposing an amendment to UN Regulation No. 43 to avoid administrative burdens on small glazing which were not required for the driver’s forward or rearward field of vision. The expert from Turkey raised concerns on possible injury risk by glazing fractures in case of a lateral collision. The expert from France underlined the need to correct the French translation. The expert from Germany raised concerns and preferred to defer the adoption of the document to the next session of GRSG.

19. GRSG agreed to remove the square brackets, but to keep the text and figures. GRSG adopted ECE/TRANS/WP.29/GRSG/2014/14 and requested the secretariat to submit it to WP.29 and AC.1, as a separate document, for consideration at their November 2014 sessions, as draft Supplement 3 to the 01 series of amendments to UN Regulation No. 43, subject to a final review by GRSG at its October 2014 session.

20. On behalf of IGPG, the expert from France introduced document ECE/TRANS/WP.29/GRSG/2014/15 proposing new definitions on interior and exterior glazing and updated provisions of Annex 21 on the installation of safety glazing on vehicles. GRSG adopted ECE/TRANS/WP.29/GRSG/2014/15 and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions, as part (see para. 17 above) of draft Supplement 3 to the 01 series of amendments to UN Regulation No. 43.

21. The expert from CLEPA introduced GRSG-106-30 correcting an error in Annex 6 to UN Regulation No. 43, 01 series of amendments. GRSG requested the secretariat to prepare an erratum.

22. The experts from Germany and CLEPA withdrew their documents GRSG-106-02 and GRSG-106-05.

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.
