prevents steering of the vehicle, the following additional requirements shall apply.
25.2.6.1.                    It shall not be possible to adjust the lock from the 'engine on' position to the 'anti-theft' position by a single rotary or linear motion of the key.
25.2.6.2.                    Where the design of the lock to achieve the requirements of Clause 25.2.6.1 embodies 2 or more separate rotary movements of the locking device, adjustment from the 'engine-oft position to the 'anti-theft' position must require either.
25.2.6.2.1.              a design linear axial movement of the key of not less than 2 mm; or
25.2.6.2.2.              actuation of an additional blocking device separately controlled. The gear selector may constitute such a blocking device.
25.3.                                PERFORMANCE REQUIREMENTS FOR STEERING LOCKS
25.3.1.                          A steering lock shall be subjected to 2,500 cycles in each direction of the wear producing test specified in Appendix 1.

          After completion of the test the steering lock shall continue to comply with the requirements of Clauses 25.2.4, 25.2.5, 25.2.6 and 25.3.2.

25.3.2.                          When the steering lock is activated in the anti-theft position, it shall withstand without damage to the steering mechanism likely to compromise safety, the application of a minimum torque of 20 daN.m in both directions under static conditions.

25.4.                                ALTERNATIVE STANDARDS

         The technical requirements of ECE R. 18/01 'Power Driven Vehicles -Protection Against Unauthorised Use, shall be deemed to be equivalent to the technical requirements of this Rule.

APPENDIX 1

       (Clause 253.1 refers.)

WEAR-PRODUCING TEST PROCEDURE FOR PROTECTIVE DEVICES ACTING ON THE STEERING

       1. TEST EQUIPMENT

       1.1. The test equipment shall consist of:

       1.1.1. a fixture suitable for mounting the sample steering complete with the protective device attached.

       1.1.2.  a means for activating and de-activating the protective device which shall include the use of the key.

       1.1.3. a means for rotating the steering shaft relative to the protective device.

       2. TEST METHOD

       2.1. A sample of the steering complete with the protective device is attached to the fixture referred to in paragraph 1.1.1 above.

       2.2.  One cycle of the test procedure shall consist of the following operations:

       2.2.1. Start position. The protective device shall be de-activated and the steering shaft shall be rotated to a position which prevents engagement of the protective device, unless it is of the type which permits locking in any position of the steering.

       2.2.2. Set to activate. The protective device shall be moved from the de-activated to the activated position, using the key.

       2.2.3.  [*/] Activated. The steering shaft shall be rotated such that the torque on it, at the instant of engagement of the protective device shall be 5.88 Nm ± 025.

       2.2.4.  De-activated. The protective device shall be de-activated by the normal means, the torque being reduced to zero to facilitate
