the centre of the reflecting surface as defined in paragraph 2.1.1.11. of this Regulation The longitudinal direction of oscillation of the pendulum shall be parallel to the longitudinal median plane of the vehicle.

        6.1.3.2.2.4. When, under the conditions governing adjustment laid down in paragraphs 6.1.3.2.2.1. and 6.1.3.2.2.2. above parts of the mirror 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 the point of contact with the hammer is located at least 10 mm from the periphery of the reflecting surface.

        6.1.3.2.2.5. The test consists in allowing the hammer to fall from a height corresponding to a pendulum angle of 60° from the vertical so that the hammer strikes the mirror at the moment when the pendulum reaches the vertical position.

        6.1.3.2.2.6. The mirrors are subjected to impact under the following different conditions:

        6.1.3.2.2.6.1. Interior mirrors

        (a) Test 1: The points of impact shall be as defined in paragraph 6.1.3.2.2.3. above. The impact shall be such that the hammer strikes the mirror on the reflecting surface side.

        (b) Test 2: Point of impact on the edge of the protective housing, such that the impact produced makes an angle of 45° with the plane of the reflecting surface and is situated in the horizontal plane passing through the centre of that surface. The impact shall occur on the reflecting surface side.

        6.1.3.2.2.6.2. Exterior mirrors

        (a) Test 1: The point of impact shall be as defined in paragraph 6.1.3.2.2.3. or 6.1.3.2.2.4. above. The impact shall be such that the hammer strikes the mirror on the reflecting surface side.

        (b) Test 2: The point of impact shall be as defined in paragraph 6.1.3.2.2.3. or 6.1.3.2.2.4. above. The impact shall be such that the hammer strikes the mirror on the side opposite to the reflecting surface.

        Where Class II or III rear-view mirrors are fixed to the same mounting as Class IV rear-view mirrors, the above-mentioned tests shall be executed on the lower mirror. Nevertheless, the Technical Service responsible for testing may repeat one or both of these tests on the upper mirror if this is less than 2 m from the ground.

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

        6.1.3.2.3.1. Description of test

        The protective housing is placed horizontally in a device in such a way that it is possible to lock the attachment
