mounting, the above-mentioned tests shall be executed on the lower camera. Nevertheless, the Technical Service responsible for testing may repeat one or both of these tests on the upper camera if this is less than 2 m from the ground.

              6.3.2.3. Bending test on the protective housing attached to the stem (Class VII)

              6.3.2.3.1. Description of test

              The protective housing is placed horizontally in a device in such a way that it is possible to lock the attachment support adjusters firmly. In the direction of the largest dimension of the housing, the end closest to the point of attachment on the adjuster for the support shall be immobilized by a 15 mm-wide rigid stop covering the entire width of the housing.

              At the other end, a stop identical to the one described above is placed on the housing so that the specified test load can be applied to it (Figure 2).

              The end of the housing opposite to that where the force is exerted may be locked rather than held in position as shown in Figure 2.

              6.3.2.3.2. The test loading shall be 25 kilograms and shall be maintained for one minute.

              6.3.3. Results of the tests

              6.3.3.1. In the tests described in paragraph 6.3.2. above, the pendulum shall 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°.

              6.3.3.1.1. In the case of mirrors, this requirement is not applicable to mirrors stuck to the windscreen, in respect of which the requirement stipulated in paragraph 6.3.3.2. shall apply after the test.

              6.3.3.1.2. The required angle to the vertical is reduced from 20° to 10° for all Class II and Class IV devices for indirect vision and for Class III devices for indirect vision which are attached to the same mounting as Class IV devices for indirect vision.

              6.3.3.2. In the case of mirrors, should the mounting of the mirror break during the tests described in paragraph 6.3.2. above for mirrors stuck to the windscreen, the part remaining shall not project beyond the base by more than 10 mm and the configuration remaining after the test shall satisfy the conditions laid down in paragraph 6.1.1.3. of this Regulation.

              6.3.3.3. The reflecting surface shall not break during the tests described in paragraph 6.3.2. However, breakage of the reflecting surface will be allowed if one of the following conditions is fulfilled.

              6.3.3.3.1. The fragments of glass still adhere to the back of the housing or to a surface firmly attached
