than or equal to the force used during the test set out in paragraph 7.2.

       7.5. Performance requirements

        When the brakes are tested in accordance with the test procedure set out in paragraph 7.4.1.:

        (a) The stopping distance: S2 ≤  1.67 S1 – 0.67 x 0.1V

         where:

                S1 = corrected stopping distance in metres achieved in the baseline test set out in paragraph 7.2.
                S2 = corrected stopping distance in metres achieved in the hot brake stop set out in paragraph 7.4.1.
         V = specified test speed in km/h; or

            (b) The MFDD ≥  60 per cent of the MFDD recorded in the test set out in paragraph 7.2.

       8. Parking brake system test – for vehicles equipped with parking brakes

       8.1. Vehicle condition:

        (a) The test is applicable to vehicle categories L2, L5 and L4;

        (b) Laden;

        (c) Engine disconnected.

       8.2. Test conditions and procedure:

        (a) Initial brake temperature: ≤  100 °C;

        (b) Test surface gradient = 18 per cent;

        (c) Brake actuation force:

         Hand control:   ≤  400 N;

         Foot control:    ≤  500 N;

            (d) For the first part of the test, park the vehicle on the test surface gradient facing up the slope by applying the parking brake system under the conditions specified in this paragraph.  If the vehicle remains stationary, start the measurement of the test period;

            (e) On completion of the test with vehicle facing up the gradient, repeat the same test procedure with the vehicle facing down the gradient.

       8.3. Performance requirements:

        When tested in accordance with the test procedure set out in paragraph 8.2., the parking brake system shall hold the vehicle stationary for 5 minutes when the vehicle is both facing up and facing down the gradient.

       9. ABS tests

       9.1. General:

            (a) The tests are only applicable to the ABS fitted on vehicle categories L1 and L3;

            (b) The tests are to confirm the performance of brake systems equipped with ABS and their performance in the event of ABS electrical failure;

            (c) "Fully cycling" means that the anti-lock system is repeatedly modulating the brake force to prevent the directly controlled wheels from locking;

            (d) Wheel-lock is allowed as long as the stability of the vehicle is not affected to the extent that it requires the operator to release the control or causes a vehicle wheel to pass outside the test lane.

        The test series comprises the following individual tests, which may be carried out in any order:

       c. Wheel lock checks on high and low friction surfaces.                        9.5.
