sets of conditions and 4 for the third set of conditions; and

4.11.2                            in the case where the vehicle has a 'Maximum Motorcycle Speed' equal to or greater than 150 km/h, if the parameters for the fourth set of conditions are met on at least one deceleration mode within a number of deceleration modes which must not exceed 4, when testing is carried out from an initial vehicle speed within 15 km/h of 'Maximum Motorcycle Speed'.

4.12                                  Partial Failure Test

4.12.1                            The vehicle will be deemed to pass this test if all the parameters specified in clause 2.1 are met on at least one deceleration mode within a number of deceleration modes, which must not exceed 6 for each single type of potential failure including:

4.12.1.1                      each sub-system of the split system;

4.12.1.2                      inoperative 'Antilock System'; and

4.12.1.3                      inoperative 'Variable Proportioning Brake System'.

4.12.2                            One single failure must be induced prior to each set of deceleration modes and the vehicle restored at the completion of testing.

4.13                                  Parking Brake Test (for LB, LD and LE Vehicles Only)

4.13.1                            The parking brake must be tested by positioning the vehicle on a gradient of at least 30 per cent where the vertical rise is expressed as a percentage of the horizontal distance travelled to achieve this rise, such that the longitudinal axis of the vehicle is parallel to the direction of the gradient.  The parking brake must be applied, the transmission disengaged and the service brakes released, for a period of not less than 5 minutes.  The position of the vehicle on the gradient must then be reversed and the vehicle again parked for a period of not less than 5 minutes.

4.13.2                            The vehicle will be deemed to pass this test if:

4.13.2.1                      for each of the 5 minute periods it remains stationary on the gradient, or in the case where the test is carried out on a clean, dry, smooth Portland cement concrete surface there is no rotation of the wheel(s) to which the parking brake is applied; and

4.13.2.2                      the force required to apply the parking brake does not exceed 405 N in the case of a foot-operated system or 245 N in the case of a hand-operated system.

4.14                                  Second Base Line Check Procedure

         This procedure is the same as that specified in clause 4.6 as the First Base Line Check Procedure except that:

4.14.1                            the deceleration must be maintained within the range of 3.0 ± 0.2 m/s2; and

4.14.2                            independent brake tests must be performed in the case of vehicles where the front and rear brakes can be applied separately.

4.15                                  Tests With Brakes Subject to Wetting

4.15.1                            The tests must be carried out under the same
