Proposal to amend the test methods for toughened glass pursuant to Korean defect investigations involving the ceramic printed area of certain panoramic sunroofs.
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.
