Proposal to amend Annex 7 (laminated-glass panes), inserting a new paragraph 6. to allow optional 2,260 g ball test and headform test for laminated-glass panes. The proposal aims to amend UN R43 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.
