              6.3.2.2.2. Positioning of the device for indirect vision for the test

              6.3.2.2.2.1. Devices for indirect vision shall be positioned on the pendulum impact rig in such a way that the axes which are horizontal and vertical when the mirror is installed on a vehicle in accordance with the applicant's mounting instructions are in a similar position;

              6.3.2.2.2.2. When a device for indirect vision is adjustable with respect to the base, the test position shall be that in which any pivoting device is least likely to operate, within the limits of adjustment provided by the applicant;

              6.3.2.2.2.3. When the device for indirect vision has a device for adjusting its distance from the base, the device shall be set in the position in which the distance between the housing and the base is shortest;

              6.3.2.2.2.4. In the case of mirrors, when the reflecting surface is mobile in the housing, it shall be so adjusted that the upper corner, which is furthest from the vehicle, is in the position of greatest projection relative to the housing.

              6.3.2.2.3. In the case of mirrors, except in the case of test 2 for Class I mirrors (see paragraph 6.3.2.2.7.1. below), when the pendulum is in a vertical position the horizontal and longitudinal vertical planes passing through the centre of the hammer shall pass through the centre of the reflecting surface as defined in paragraph 2.1.1.10. of this Regulation. The longitudinal direction of oscillation of the pendulum shall be parallel to the longitudinal median plane of the vehicle.

              6.3.2.2.4. In the case of camera-monitor systems, when the pendulum is in a vertical position the horizontal and longitudinal vertical planes passing through the centre of the hammer shall pass through the centre of the lens or of the transparent protection part protecting the lens. The longitudinal direction of oscillation of the pendulum shall be parallel to the longitudinal median plane of the vehicle. If the test is performed with a shutter camera system, the shutter has to be open during the pendulum impact.

              6.3.2.2.5. When, under the conditions governing adjustment laid down in paragraphs 6.3.2.2.1. and 6.3.2.2.2. above parts of the device for indirect vision limit the return of the hammer, the point of impact shall be displaced in a direction perpendicular to the axis of rotation or pivoting in question.

              The displacement shall be no greater than is strictly necessary for the execution of the test; it shall be limited in such a way that:

                  (a) Either the sphere delimiting the hammer remains at least tangential to the cylinder as defined in paragraph 6.1.1.6.;

                  (b) Or, in the case of mirrors, the point of contact with the hammer
