mirror provides the field of vision specified in paragraph 15.2.4.6. of this Regulation.

        6.1.2.1.6. Mirrors for category L vehicles with bodywork (Class VII)

        6.1.2.1.6.1. "Main" exterior mirrors (Class VII)

        The minimum dimensions of the reflecting surface shall be such that:

        (a) Its area shall not be less than 6, 900 mm2;

        (b) The diameter of circular mirrors shall not be less than 94 mm;

        (c) Where rear view mirrors are not circular, their dimensions shall enable a 78 mm-diameter circle to be prescribed on their reflecting surface.

        The maximum dimensions of the reflecting surface shall be such that:

        (a) The diameter of any circular rear view mirror shall not be greater than 150 mm;

        (b) The reflecting surface of any non-circular rear view mirror shall lie within a rectangle measuring 120 mm x 200 mm.

        6.1.2.2. Reflecting surface and coefficients of reflection

        6.1.2.2.1. The reflecting surface of a mirror shall be either flat or spherically convex. Exterior mirrors may be equipped with an additional aspherical part provided that the main mirror fulfils the requirements of the indirect field of vision.

        6.1.2.2.2. Differences between the radii of curvature of mirrors

        6.1.2.2.2.1. The difference between ri or r'i, and rp at each reference point shall not exceed 0.15 r.

        6.1.2.2.2.2. The difference between any of the radii of curvature (rp1, rp2, and rp3) and r shall not exceed 0.15 r.

        6.1.2.2.2.3. When r is not less than 3,000 mm, the value of 0.15 r quoted in paragraphs 6.1.2.2.2.1. and 6.1.2.2.2.2. above is replaced by 0.25 r.

        6.1.2.2.3. Requirements for aspherical parts of mirrors

        6.1.2.2.3.1. Aspherical mirrors shall be of sufficient size and shape to provide useful information to the driver. This normally means a minimum width of 30 mm at some point.

        6.1.2.2.3.2. The radius of curvature ri of the aspherical part shall not be less than 150 mm.

        6.1.2.2.4. Value of "r" for spherical mirrors shall not be less than:

        6.1.2.2.4.1. 1,200 mm for interior rear-view mirrors (Class I);

        6.1.2.2.4.2. 1,200 mm for Class II and III main exterior rear-view mirrors;

        6.1.2.2.4.3. 300 mm for "wide-angle" exterior mirrors (Class IV) and "close-proximity" exterior mirrors (Class V);

        6.1.2.2.4.4. 200 mm for front mirrors (Class VI).

        6.1.2.2.4.5. 1,000 mm or more than 1,500 mm in the case of Class VII mirrors

       6.1.2.2.5. The value of the normal coefficient of reflection, as determined according to the method described in Annex 6, shall be not less than 40 per cent.

       In the case of reflecting surfaces with a changeable degree of reflection, the "day" position shall allow the colours of the signals used for road traffic to be recognized. The value of the normal coefficient of reflection in the "night" position shall be not less
