parts of Class I mirrors which are made of a material with a Shore A hardness of less than 50 and which are mounted on a rigid support, the requirements of paragraphs 6.1.1.2. and 6.1.1.3. above shall only apply to the support.

              6.1.2. Special specifications

              6.1.2.1. Dimensions

              6.1.2.1.1. Rear-view mirrors (Class I)

              The dimensions of the reflecting surface shall be such that it is possible to inscribe thereon a rectangle one side of which is 40 mm and the other 'a' mm in length, where

and "r" is the radius of curvature.
              6.1.2.1.2. Main rear-view mirrors (Classes II and III)

              6.1.2.1.2.1. The dimensions of the reflecting surface shall be such that it is possible to inscribe therein:

                  (a) A rectangle 40 mm high the base length of which, measured in millimetres, has the value "a";

                  (b) A segment which is parallel to the height of the rectangle and the length of which, expressed in millimetres, has the value "b".

              6.1.2.1.2.2. The minimum values of "a" and "b" are given in the table below:

Class of rear-view mirror  a [mm]  b [mm]
II                                 200
III                                70

6.1.2.1.3. "Wide-angle" view mirrors (Class IV)
              The contours of the reflecting surface shall be of simple geometric form and its dimensions such that it provides, if necessary in conjunction with a Class II exterior mirror, the field of vision specified in paragraph 15.2.4.4. of this Regulation.

              6.1.2.1.4. "Close-proximity" view mirrors (Class V)

               The contours of the reflecting surface shall be of simple geometric form and its dimensions such that the mirror provides the field of vision specified in paragraph 15.2.4.5. of this Regulation.

              6.1.2.1.5. Front-view mirrors (Class VI)

               The contours of the reflecting surface shall be of simple geometric form and its dimensions such that the 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" rear-view 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 convex. Exterior mirrors may be equipped with an additional
