may be increased to the minimum time required by the vehicle to achieve the specified initial speed and to maintain it for 10 seconds before each successive deceleration mode.
7.9.9.                              Vehicles must attain a sustained deceleration of not less than 3 m/s2 during the first deceleration mode.  Subsequent deceleration must be conducted employing a 'Control' force not less than that established during the first deceleration mode without regard to the actual deceleration achieved.
7.9.10.                          The Service Brake Fade Test must be followed immediately by the Service Brake Fade Effectiveness Check.
7.10.                                Service Brake Fade Effectiveness Check
           The vehicle must be accelerated over a distance not exceeding 1.6 km from the final speed attained at the conclusion of the deceleration mode of the Service Brake Fade Test to the initial speed specified in Table 1 (Item 10) and the test carried out in accordance with that Item.  The vehicle must be deemed to satisfy the requirements of this test if the deceleration achieved is not less than that specified in Table 1 (Item 10).
7.11.                                Parking Brake Test
7.11.1.                          This test must be conducted on a gradient of at least 18 percent, where the vertical rise is expressed as a percentage of the horizontal distance travelled to achieve this rise.  The vehicle must be positioned on the gradient such that its longitudinal axis is parallel to the direction of the gradient.  The 'Parking Mechanism 35/...' (if fitted) must be disengaged.  The service brake must be applied, transmission disengaged, and parking brake must be applied by a single application of the force specified, except that a series of applications to achieve the specified force may be made in the case of a parking brake design that does not allow the application of the specified force in a single application.  The service brake must be released, for a period of not less than 5 minutes.  The vehicle must then be parked in the reverse position on the gradient for not less than 5 minutes with the vehicle in condition described above.
7.11.2.                          The vehicle is deemed to pass this test if:
7.11.2.1.                    for each of the 5 minute periods it remains stationary on the gradient; and
7.11.2.2.                    the force required to actuate the parking brake does not exceed 685 N in the case of a foot-operated parking brake, and does not exceed 590 N applied at the centre of the handgrip, or not closer than 35 mm from the free end of the actuation lever, in the case of a hand-operated parking brake.
7.11.3.                          If the vehicle does not remain stationary re-application of the service brake to hold the vehicle stationary, with re-application of the specified force to the parking brake 'Control' (without
