be made to ensure that the mobile index records this measurement.

    2.1.4        The apparatus for measuring projections is illustrated in the figure of the appendix to this annex.

    2.2              Test procedure

    2.2.1        A cavity shall be formed in the headform by pulling back the ram and the mobile index shall be placed against the ram.
    2.2.2        The apparatus shall be applied to the projection to be measured so that the headform contacts the maximum surrounding surface area with a force not exceeding 2 daN.

    2.2.3        The ram shall be pushed forward until it makes contact with the projection to be measured and the amount of the projection shall be observed on the scale.

    2.2.4        The headform shall be adjusted to obtain maximum projection. The amount of the projection shall be recorded.

    2.2.5        If two or more controls are situated sufficiently close for the ram or the headform to contact them simultaneously, they shall be treated as follows:

       2.2.5.1              Multiple controls, all of which can be contained in the headform cavity, shall be regarded as forming a single projection.

       2.2.5.2              If other controls prevent normal testing by contacting the headform, they shall be removed and the test shall be conducted without them. They may subsequently be reinstalled and tested in their turn with other controls that have been removed to facilitate the procedure.

Annex 7

APPARATUS AND PROCEDURE FOR APPLICATION OF PARAGRAPH 5.2.1. OF THIS REGULATION

Those parts (switches, pull-knobs, etc.) which can be contacted by using the apparatus and procedure described below shall be considered as being likely to be contacted by the knees of an occupant. Footoperated controls are fitted as foot pedals.

      1. Apparatus

    1.1              Diagram of apparatus

    2.                   Procedure

    The apparatus may be placed in any position below the level of the instrument panel so that:

    2.1              the plane XX' remains parallel to the median longitudinal plane of the vehicle;

    2.2              the axis X can be rotated above and below the horizontal through angles up to 30 degrees.

    3.                   In carrying out the above test, all materials of less than 50 shore A hardness shall be removed.

Annex 8

DETERMINATION OF A DYNAMICALLY DETERMINED HEAD IMPACT ZONE

      1. Determination of the dynamically determined head impact zone with regard to the protective system

    1.1              Differing from the procedure described in annex 1 the applicant may prove, by a procedure accepted by the technical service responsible for conducting the tests, that a dynamically determined head impact zone is relevant for this vehicle type.

    1.2              A suitable method to prove a dynamically determined head impact zone may be either:

    1.2.1        Vehicle impact tests to determine the sequence of movement of the occupants with regard to the protective system installed in
