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 adds the marking ā/Dā to signify laminated-glass panes subjected to the 2,260 g ball test and the headform test. The proposal aims to enable the approval of 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.
