Results of the tests. 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°.
Results of the tests. 8.4.1. In the tests described in paragraph 8.2. above, the pendulum shall return in such a way that the projection on the release plane of the position taken by the arm makes an angle of at least 20º with the vertical.
Results of the tests. 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°. 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. 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.
