23. The expert from Germany, chairing the Informal group on Plastic Glazing (IGPG), reported on the progress made by the group during its sixth meeting in January 2013 (GRSG-104-24). He presented GRSG-104-43 proposing a first set of amendments to UN Regulation No. 43 that would introduce requirements on plastic glazing for windscreens and laminated plastic panes other than windscreens. He underlined the need to further discuss the abrasion tests for plastic windscreen material and initiate round robin tests to ensure the accuracy of the equipment and tools for such tests. In this respect, he sought the consent of GRSG to extend the mandate of the informal group (GRSG-104-40) and, accordingly, he presented the amended Terms of References of IGPG (GRSG-104-41) and also the updated time schedule (GRSG-104-42) for concluding these tasks. GRSG welcomed that information and endorse the request. GRSG agreed to keep GRSG-104-43 on the agenda as a reference document. The GRSG Chair volunteered to inform WP.29 on the extended mandate of IGPG.

24. The expert from Germany introduced GRSG-104-48 proposing a number of editorial corrections to Revision 3 of UN Regulation No. 43. GRSG adopted the proposed corrections, as reproduced in Annex V to the meeting report [see the addendum GRSG/83/Add.1], and requested the secretariat to submit the amendment to WP.29 and AC.1 for consideration at their November 2013 sessions as Corrigendum 2 to Revision 3 to UN Regulation No. 43.

25. Recalling the discussion at the previous session of GRSG on difficulties fulfilling the barometric pressure conditions required for the impact test (due to a high altitude of the test location), the expert from Germany announced his intention to prepare a concrete proposal for consideration at the next GRSG sessions.
