In the tests described in paragraph 6.1.3.2, the pendulum must continue to swing after impact in such a way that the projection of the position assumed by the arm on the plane of release makes an angle of at least 20° with the vertical. The accuracy of measurement of the angle shall be within ± 1°.
6.1.3.3.1.1. This requirement is not applicable to mirrors stuck to the windscreen, in respect of which the requirement stipulated in paragraph 6.1.3.3.2 shall apply after the test.
6.1.3.3.1.2. The required angle to the vertical is reduced from 20° to 10° for all Class II and Class IV rear-view mirrors and for Class III rear-view mirrors which are attached to the same mounting as Class IV mirrors.
6.1.3.3.2. Should the mounting of the mirror break during the tests described in paragraph 6.1.3.2 for mirrors stuck to the windscreen, the part remaining must not project beyond the base by more than 10 mm and the configuration remaining after the test must satisfy the conditions laid down in paragraph 6.1.1.3.
The reflecting surface must not break during the tests described in paragraph 6.1.3.2. However, breakage of the reflecting surface will be allowed if one of the following conditions is fulfilled:
6.1.3.3.3.1. the fragments of glass still adhere to the back of the housing or to a surface firmly attached to the housing; partial separation of the glass from its backing is admissible provided 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, must 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 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 shall only apply to the support.
6.2.2.2. Functional requirements
