UNIFORM PROVISIONS CONCERNING THE APPROVAL OF SAFETY GLAZING MATERIALS
AND THEIR INSTALLATION ON VEHICLES
Regulation No. 43
“Toughened-glass pane” means a glass pane consisting of a single layer of glass which has been subjected to special treatment to increase its mechanical strength and to condition its fragmentation after shattering;
“Double-glazed unit” means an assembly of two glazing panes permanently assembled in manufacture and separated by a uniform gap;
“Type of safety glazing material” means a glazing as defined in paragraphs 2.1. to 2.7. not exhibiting any essential differences, with respect, in particular, to the principal and secondary characteristics defined in annexes 4 to 12 and 14 to 16;
Every piece of safety glazing material, including the samples and test pieces submitted for approval, shall bear a trade name or mark as listed under item 3 of annex 1. Manufactured parts must bear the ECE Regulation No. 43 number allocated to the prime manufacturer. The marking shall be clearly legible and indelible.
All glazing materials, including glazing material for the manufacture of windscreens, shall be such that, in the event of shattering, the danger of bodily injury is reduced as far as possible. The glazing material shall be sufficiently resistant to the incidents likely to occur in normal traffic, and to atmospheric and temperature conditions, chemical action, combustion and abrasion.
The purpose of this test is:
To verify that the fragments and splinters produced by fracture of the glass pane are such as to minimize the risk of injury, and
