Proposal to amend GRSG/2018/7 by adding the marking “/D” to signify laminated-glass panes subjected to the 2,260 g ball test and the headform test.

Proposal to enable the approval of the laminated-glass panes with improved mechanical properties, especially as designed for front, exterior, forward-facing glazing of the upper deck of a double-deck vehicle. This request follows the approval by GRSG of a similar amendment to UN R43 (document GRSG/2018/7) and therefore seeks to maintain the alignment between GTR 6 and UN R43.

Proposal to enable the approval of the laminated-glass panes with improved mechanical properties, especially as designed for front, exterior, forward-facing glazing of the upper deck of a double-deck vehicle. This request follows the approval by GRSG of a similar amendment to UN R43 (document GRSG/2018/7) and therefore seeks to maintain the alignment between GTR 6 and UN R43.

The objective of this proposal is to develop, in the framework of the 1998 Agreement, an amendment to UN Global Technical Regulation (UN GTR) No. 6 on Safety Glazing to adapt the Regulation to technical progress by providing optional use of thinner laminated-glass panes meeting mechanical strength requirements in front, exterior, forward-facing glazing of upper deck of double decked buses instead of laminated windscreen.
