Description of the test. 8.2.2.1. The procedure used to clamp the rear‑view mirror to the support shall be that recommended by the manufacturer of the device, or, where appropriate, by the vehicle manufacturer. 8.2.2.2. Positioning the rear‑view mirror for the test. 8.2.2.2.1. Rear‑view mirrors shall be positioned on the pendulum impact rig such that the axes which are horizontal and vertical when installed on a vehicle in accordance with the vehicle or rear‑view mirror manufacturers' mounting instructions, are in a similar position. 8.2.2.2.2. When a rear‑view mirror is adjustable in relation to the base, the test position shall be the least favourable for any pivoting device to operate within the limits provided by the mirror or vehicle manufacturer. 8.2.2.2.3. When the rear‑view mirror has a device for adjusting its distance from the base, the device shall be set in the position where the distance between the holder and the base is shortest. 8.2.2.2.4. When the reflecting surface is mobile in the holder, it shall be adjusted so that the upper corner which is furthest from the vehicle, is in the position of greatest projection relative to the holder. 8.2.2.3. When the pendulùm 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 mirror as defined in paragraph 2.7. above. The longitudinal direction of oscillation of the pendulum shall be parallel to the longitudinal plane of the vehicle. 8.2.2.4. When, under the conditions governing adjustment prescribed in paragraphs 8.2.2.2.1. and 8.

Description of the test. 8.2.2.1. The procedure used to clamp the rear‑view rear-view mirror to the support shall be that recommended by the manufacturer of the device, or, where appropriate, by the vehicle manufacturer.
8.2.2.2. Positioning the rear‑view rear-view mirror for the test.
8.2.2.2.1. Rear‑view Rear-view mirrors shall be positioned on the pendulum impact rig such that the axes which are horizontal and vertical when installed on a vehicle in accordance with the vehicle or rear‑view rear-view mirror manufacturers' mounting instructions, are in a similar position.
8.2.2.2.2. When a rear‑view rear-view mirror is adjustable in relation to the base, the test position shall be the least favourable for any pivoting device to operate within the limits provided by the mirror or vehicle manufacturer.
8.2.2.2.3. When the rear‑view rear-view mirror has a device for adjusting its distance from the base, the device shall be set in the position where the distance between the holder and the base is shortest.
8.2.2.2.4. When the reflecting surface is mobile in the holder, it shall be adjusted so that the upper corner which is furthest from the vehicle, is in the position of greatest projection relative to the holder.
8.2.2.3. When the pendulùm 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 mirror as defined in paragraph 2.7. above. The longitudinal direction of oscillation of the pendulum shall be parallel to the longitudinal plane of the vehicle.
8.2.2.4. When, under the conditions governing adjustment prescribed in paragraphs 8.2.2.2.1. and 88.2.2.2.2. above, parts of the rear-view mirror limit the return of the hammer, the point of impact shall be shifted in a direction perpendicular to the axis of rotation or pivot in question. This displacement shall be that which is strictly necessary for the implementation of the test. It shall be limited in such a way that the point of contact of the hammer is located at least 10 mm from the periphery of the reflecting surface.
8.2.2.5. The test consists in allowing the hammer to fall from a height corresponding to a pendulum angle of 60º from the vertical so that the hammer strikes the rear-view mirror at the moment when the pendulum reaches the vertical position.
8.2.2.6. The rear-view mirrors are subjected to impact in the following different conditions:
