special purposes where, due to its special features, it is not possible to meet this requirement, the obstruction of the required field of vision of a Class VI mirror caused by the special features may be more than 10 per cent but not more than necessary for its special function.

       15.2.4.10. Test procedure

        The field of vision shall be determined by placing powerful light sources at the ocular points and examining the light reflected on the vertical monitoring screen. Other equivalent methods may be used.

       15.3. Devices for indirect vision other than mirrors

       15.3.1. A device for indirect vision shall give such performances that a critical object can be observed by the driver over the entire required field of vision, taking into account the critical perception according the procedure of Annex 10.

       Alternatively, the determination of the displayed object size shall be performed according to Annex 11.

       15.3.2. Obstruction of the driver's direct view caused by the installation of a device for indirect vision shall be restricted to a minimum.

       15.3.3. (Reserved)

       15.3.4. Installation requirements for the monitor

        The viewing direction of the monitor shall roughly be the same direction as the one for the main mirror.

       15.3.5. Vehicles may be equipped with additional devices for indirect vision.

       15.3.6. The provisions of this Regulation do not apply to the surveillance camera-monitor-recording devices defined in paragraph 2.1.2.13. of this Regulation. Exterior surveillance cameras either shall be mounted at least 2 m above the ground when the vehicle is under a load corresponding to its maximum technical permissible mass, or, if their lower edge is less than 2 m from the ground, shall not project more than 50 mm beyond the overall width of the vehicle measured without this device and have a radii of curvature of not less than 2.5 mm.

16.  Modifications of the vehicle type and extension of approval

       16.1. Every modification of the vehicle type shall be notified to the Type Approval Authority which approved the vehicle type. Type Approval Authority shall then either:

       (a) Decide, in consultation with the manufacturer, that a new type approval is to be granted, or

       (b) Apply the procedure contained in paragraph 16.1.1. (Revision) and, if applicable, the procedure contained in paragraph 16.1.2. (Extension).

       16.1.1. Revision

        When particulars recorded in the information folder have changed and the Type Approval Authority considers that the modifications made are unlikely to have an appreciable adverse effect, and that in any case the vehicle still complies with the requirements, the modification shall be designated a "revision".

        In such a case, the Type Approval Authority shall issue the revised pages of the information folder as necessary, marking each revised page to show clearly the nature of the
