Proposal for an amendment to provide for the optional use of laminated-glass panes meeting mechanical strength requirements in front, exterior, forward-facing glazing of upper deck of double decked buses instead of laminated windscreen. This is in line with similar proposal discussed in 114th session of GRSG for UN Regulation No. 43.

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.

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.
