13. The expert from Germany reported on the work progress made by the informal group on plastic glazing (GRSG-102-14). He added that the group was still waiting for the results of the abrasion test still under discussion by the International Standard Organization (ISO) working group, especially with respect to the influence of the quality of the abrasion wheels. GRSG welcomed the information and noted some comments.

14. The expert from Germany introduced GRSG-102-24 proposing to amend UN Regulation No. 43 to allow type approval of multiple-glazed units having more than two glass panes. GRSG noted a number of comments. The expert from CLEPA raised a study reservation and underlined the need to also align UN Global Technical Regulation (UN GTR) No. 6 on safety glazing. GRSG agreed to resume consideration of this subject at its next session in October 2012 on the basis of an official document. GRSG invited the expert from Germany to transmit in due time to the secretariat an updated proposal taking into account the comments received and a proposal for transitional provisions, if necessary.
