Pursuant to its defect investigations concerning the shattering of certain panoramic sunroofs, Korea proposes the establishment of an informal working group to prepare amendments to UN Regulation No. 43 and GTR No. 6 to specify test methods for evaluating panoramic sunroof glazing.

The main objective of this proposal is to develop an amendment to UN GTR No. 6 on Safety Glazing concerning clarification of the methods (e.g. 227g ball drop test), etc. for testing and evaluating the mechanical strength of toughened glass so that the safety of a panoramic sunroof is assured.
