the test must be carried out at the speeds prescribed for each type of test; if the maximum design speed of a vehicle is lower than the speed prescribed for a test, the test shall be performed at the vehicle's maximum speed;

         1.2.3. during the tests, the force applied to the brake control in order to obtain the prescribed performance must not exceed the maximum force laid down;

         1.2.4. the road must have a surface affording good adhesion, unless specified otherwise in the relevant annexes;

         1.2.5. the tests must be performed when there is no wind liable to affect the results;

         1.2.6. at the start of the tests, the tyres must be cold and at the pressure prescribed for the load actually borne by the wheels when the vehicle is stationary;

         1.2.7. The prescribed performance must be obtained without locking of the wheels at speeds exceeding 15km/h, without deviation of the vehicle from a 3.5 m wide lane, without exceeding a yaw angle of 15 degrees and without abnormal vibrations.

         l.2.8. for electric vehicles with motor(s) permanently connected to the wheels all tests will be carried out with the motor(s) connected;

         l.2.9. for electric vehicles as described in paragraph 1.2.8., fitted with an electric regenerative braking system of category A, behaviour tests defined in paragraph 1.4.3.1. of this annex shall be carried out on a track with a low adhesion coefficient (as defined in paragraph 5.2.2. of annex 6);

         1.2.9.1. moreover, for vehicles fitted with an electric regenerative braking system of category A, transient conditions as gear changes or accelerator control release must not affect the behaviour of the vehicle in condition described in paragraph 1.2.9.;

         1.2.10. in the tests provided in paragraphs 1.2.9. and 1.2.9.1. wheel locking is not allowed. However, steering correction is permitted if the angular rotation of the steering control is within 120 degrees during the initial 2 seconds and not more than 240 degrees in all.

1.3. Behaviour of the vehicle during braking

         1.3.1. In braking tests, and in particular in those at high speed, the general behaviour of the vehicle during braking must be checked.

         1.3.2. The behaviour of the vehicle on a road on which adhesion is reduced must meet the requirements of annex 5 to this Regulation.

1.4. Type-0 test (ordinary performance test with cold brakes)

1.4.1. General

         1.4.1.1. The average temperature of the service brakes on the hottest axle of the vehicle, measured inside the brake linings or on the braking path of the disc or drum, is between 65 and 100 degrees C prior to any brake application.

1.4.1.2. The test must be conducted in the following conditions:

         1.4.1.2.1. the vehicle must be laden, the distribution of its mass among
