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.
6.2. Safety glazing materials shall in addition be sufficiently transparent, shall not cause any noticeable distortions of objects as seen through the windscreen, and shall not give rise to any confusion between the colours used in road-traffic signs and signals. In the event of the windscreen's shattering, the driver shall still be able to see the road clearly enough to be able to brake and stop his vehicle safely.
7.  Particular requirements
 All types of safety glazing shall, depending on the category to which they belong, comply with the following particular requirements:
7.1. As regards toughened-glass windscreens, the requirements contained in Annex 4;
7.2. As regards uniformly-toughened glass panes, the requirements contained in Annex 5;
7.3. As regards ordinary laminated-glass windscreens, the requirements contained in Annex 6;
7.4. As regards ordinary laminated-glass panes, the requirements contained in Annex 7;
7.5. As regards treated laminated-glass windscreens, the requirements contained in Annex 8;
7.6. As regards safety glazing faced with plastics material, in addition to the relevant requirements listed above, the requirements contained in Annex 9;
7.7. As regards glass-plastics windscreens, the requirements contained in Annex 10;
7.8. As regards glass-plastics panes, the requirements contained in Annex 11;
7.9. As regards multiple-glazed units, the requirements contained in Annex 12;
7.10. As regards rigid plastic panes, the requirements contained in Annex 14;
7.11. As regards flexible plastic panes, the requirements contained in Annex 15;
7.12. As regards rigid plastic multiple-glazed units, the requirements contained in Annex 16.

8.  Tests
8.1. The following tests are prescribed in this Regulation:
8.1.1. Fragmentation test
 The purpose of this test is:
8.1.1.1. To verify that the fragments and splinters produced by fracture of the glass pane are such as to minimize the risk of injury, and
8.1.1.2. In the case of windscreens, to check residual visibility after shattering.
8.1.2. Mechanical strength test
8.1.2.1. Ball-impact test
 There are two forms of tests, one using a 227 g ball and one using a 2,260 g ball.
              8.1.2.1.1. 227 g ball test:  The purpose of this test is to assess the adhesion of the interlayer of laminated glass and the mechanical strength of uniformly-toughened glass and plastic glazings.
              8.1.2.1.2. 2,260 g ball test:  The purpose of this test is to assess ball-penetration resistance of laminated glass.
       8.1.2.2. Headform test
 The purpose of this test is to verify the compliance of glazing with the requirements relating to the limitation of injury in the event of impact of the head against the windscreen, laminated glass and glazing of glass-plastic and rigid plastic
