The secondary characteristics are as follows: 1.2.1. The nature of the material (polished (plate) glass, float glass, sheet glass), 1.2.2. The colouring (total or partial) of the interlayer or interlayers (colourless or tinted), 1.2.3. The colouring of the glass (colourless or tinted), 1.2.4. The incorporation or otherwise of conductors, 1.2.5. The incorporation or otherwise of opaque obscuration.

Optical qualities. The requirements concerning optical qualities set out in Annex 3, paragraph 9., shall apply to every type of windscreen. This shall not apply to flat windscreens which fall within an already approved group if the rake angle is less than 40° to the vertical. 1. Definition of type Laminated-glass panes shall be deemed to belong to different types if they differ in at least one of the following principal or secondary characteristics. 1.1. The principal characteristics are as follows: 1.1.1. The trade names or marks. 1.1.2. The thickness category of the pane in which the nominal thickness 'e' lies, a manufacturing tolerance of ±0.2 . n mm ('n' being the number of layers of glass in the pane) being allowed: Category I e  5.5 mm Category II 5.5 mm < e  6.5 mm Category III 6.5 mm < e 1.1.3. The nominal thickness of the interlayer or interlayers, 1.1.4. The nature and type of the interlayer or interlayers, e.g. PVB or other plastics-material interlayer or interlayers,

Definition of type Uniformly-toughened glass panes shall be deemed to belong to different types if they differ in at least one of the following principal or secondary characteristics. 1.1. The principal characteristics are as follows: 1.1.1. The trade names or marks; 1.1.2. The nature of the toughening process (thermal or chemical); 1.1.3. The shape category; two categories are distinguished: 1.1.3.1. Flat glass panes, 1.1.3.2. Flat and curved glass panes. 1.1.4. The thickness category in which the nominal thickness 'e' lies (a manufacturing tolerance of ±0.2 mm being allowed): Category I e ≤ 3.5 mm Category III 4.5 mm < e ≤ 6.5 mm Category IV 6.5 mm < e 1.2. The secondary characteristics are as follows: 1.2.1. Nature of the material (polished (plate) glass, float glass, sheet glass); 1.2.2. Colouring (colourless or tinted); 1.2.3. The incorporation or otherwise of conductors. 1.2.4. The incorporation or otherwise of opaque obscuration. 2. Fragmentation test 2.1. Indices of difficulty of the secondary characteristics No other secondary characteristics are involved. * This type of uniformly-toughened glass pane can also be used for windscreens for slow-moving vehicles which, by construction, cannot exceed 40 km/h.
