that this does not exceed 2.5 mm on either side of the cracks. It is permissible for small splinters to become detached from the surface of the glass at the point of impact;

       6.1.3.3.3.2. The reflecting surface is made of safety glass.

       6.2. Devices for indirect vision other than mirrors

       6.2.1. General requirements

       6.2.1.1. If adjustment by the user is needed, the device for indirect vision shall be               adjustable without the use of tools.

       6.2.1.2. If a device for indirect vision can only render the total prescribed field of vision by scanning the field of vision, the total process of scanning, rendering and reset to its initial position together shall not take more than 2 seconds.

       6.2.2. Camera-monitor devices for indirect vision

       6.2.2.1. General requirements

       6.2.2.1.1. When the camera-monitor device for indirect vision is mounted on a plane surface, all parts, irrespective of the adjustment position of the device which are in potential, static contact with a sphere either 165 mm in diameter in the case of a monitor or 100 mm in diameter in the case of a camera, shall have a radius of curvature "c" of not less than 2.5 mm.

       6.2.2.1.2. Edges of fixing holes or recesses of which the diameter or longest diagonal is less than 12 mm are exempt from the radius requirements of paragraph 6.2.2.1.1. above provided that they are blunted.

       6.2.2.1.3. For parts of the camera and the monitor which are made of a material with a Shore A hardness of less than 60 and which are mounted on a rigid support, the requirements of paragraph 6.2.2.1.1. above shall only apply to the support.

       6.2.2.2. Functional requirements

       6.2.2.2.1. The camera shall function well in conditions in which sunlight falls on the camera. The saturated area, defined as the area in which the luminance contrast ratio (C=Lw/Lb) of a high contrast pattern falls below 2.0, shall not cover more than 15 per cent of the displayed image under the conditions of paragraphs 6.2.2.2.1.1. to 6.2.2.2.1.4. below.

       In case the camera system shows dynamical changes in the blooming area during the test the maximum blooming area should fulfill the requirement.

       6.2.2.2.1.1. A black and white test pattern, having a minimum contrast ratio of 20 shall be positioned in front of the camera.

       The test pattern shall be evenly illuminated at an illumination of 3,000 ± 300 Lx.

       The test pattern shall be medium gray on average and cover the complete area viewed by the camera; the camera shall view no other objects than the test pattern.

       6.2.2.2.1.2. The camera shall be hit by a (simulated sun) light of 40 kLx, spanning an angle between 0.6 and 0.9 degrees with an elevation angle of 10 degrees
