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 (directly or indirectly via a mirror) removed from the optical axis of the sensor.

       The light source shall:

       (a) Have a spectrum D65 with a tolerance of ±1,500K;

       (b) Be homogeneous in space and time within a tolerance of 2 kLx.

       The emission of the light source in infrared shall be negligible.

       6.2.2.2.1.3. There shall be no ambient illumination of the monitor during the test.

       6.2.2.2.1.4. An example of the set-up is given in the Figure A below.

           4:  High intensity light.

           5:  Camera.

           6:  Monitor.

       6.2.2.2.2. The monitor shall render a minimum contrast under various light conditions as specified by ISO 15008:2003.

       6.2.2.2.3. It shall be possible to adjust the average luminance of the monitor either manually or automatically to the ambient conditions.

       6.2.2.2.4. The measurements for the luminance contrast of the monitor shall be carried out according to ISO 15008:2009.

       6.2.3. Other devices for indirect vision

        It has to be proved that the device meets the following requirements:

       6.2.3.1. The device shall perceive the visual spectrum and shall always render this image without the need for interpretation into the visual spectrum.

       6.2.3.2. The functionality shall be guaranteed under the circumstances of use in which the system shall be put into service. Depending on the technology used in obtaining images and presenting them paragraph 6.2.2.2. above shall be entirely or partly applicable. In other cases this can be achieved by establishing and demonstrating by means of system sensitivity analogous to paragraph 6.2.2.2. above that a function is ensured that is comparable to or better than what is required for and by demonstrating that a functionality is guaranteed that is equivalent or better than that required for mirror- or camera-monitor type devices for indirect vision.

7.  Modification of the type of device for indirect vision and extension of approval

       7.1. Every modification to an existing type of device for indirect vision including its connection to the bodywork shall be notified to the Type Approval Authority which approved the type of device for indirect vision. The 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 7.1.1. (Revision) and, if applicable, the procedure contained in paragraph 7.1.2. (Extension).
