space referred to in paragraph 4.2. above, to every rear‑view mirror conforming to a type approved under this Regulation, in addition to the mark prescribed in paragraph 4.1., an international approval mark consisting of:
5.4.1. A circle surrounding the letter "E" followed by the distinguishing number of the country which has granted approval[3],
5.4.2. An approval number,
5.4.3. An additional symbol in the form of the letter "L".
5.5. The approval mark and the additional symbol shall be clearly legible and be indelible.
5.6. Annex 3 to this Regulation gives an example of the arrangement of the approval mark and additional symbol.
6.  General requirements
6.1. All rear‑view mirrors shall be adjustable.
6.2. The edge of the reflecting surface shall be enclosed in a holder which, on its perimeter, shall have a value of "c" ≥ 2.5 mm at all points and in all directions.  If the reflecting surface projects beyond the holder, the radius of curvature "c" of the edge of the projecting part shall be not less than 2.5 mm and shall return into the holder under a force of 50 N applied to the point of greatest projection relative to the holder in a horizontal direction approximately parallel to the longitudinal median plane of the vehicle.
6.3 When the rear‑view mirror is mounted on a plane surface, all its parts, irrespective of the adjustment position of the device, including those parts remaining attached to the holder after the test set out in paragraph 8.2., which are in potential static contact with a sphere 100 mm in diameter shall have a radius of curvature "c" of not less than 2.5 mm.
6.3.1. Edges of fixing holes or recesses, which are less than 12 mm in width are exempt from the radius requirements of paragraph 6.3. provided they are blunted.
6.4. The parts of rear‑view mirrors that are made of a Shore A hardness not greater than 60 are exempt from the provisions set out in paragraphs 6.2. and 6.3. above.
7.  Special specifications
7.1. Dimensions
7.1.1. The minimum dimensions of the reflecting surface must be such that:
7.1.1.1. The area shall not be less than 69 cm2,
7.1.1.2. In the case of circular mirrors, the diameter shall not be less than 94 mm,
7.1.1.3. In the case of non‑circular mirrors, the dimension will permit the inscription of a circle with a diameter of 78 mm on the reflecting surface.
7.1.2. The maximum dimensions of the reflecting surface must be such that:
7.1.2.1. In the case of circular mirrors, the diameter shall not be greater than 150 mm,
7.1.2.2. In the case of non‑circular mirrors, the reflecting surface shall fit into a rectangle measuring 120 mm by 200 mm.
