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 the axles being that stated by the manufacturer; where provision is made for several arrangements of the load on the axles the distribution of the maximum mass among the axles must be such that the mass on each axle is proportional to the maximum permissible mass for each axle;

         1.4.1.2.2. every test must be repeated on the unladen vehicle; there may be, in addition to the driver, a second person on the front seat who is responsible for noting the results of the test;

         1.4.1.2.3. the limits prescribed for minimum performance, both for tests with the vehicle unladen and for tests with the vehicle laden, shall be those laid down hereunder; the vehicle must satisfy both the prescribed stopping distance and the prescribed mean fully developed deceleration, but it may not be necessary to actually measure both parameters;

         1.4.1.2.4. the road must be level; unless otherwise specified each test may comprise up to six stops including any needed for familiarization.

         1.4.2. Type-0 test with engine disconnected, service braking in accordance with paragraph 2.1.1. (A) of this annex.

          The test must be carried out at the speed prescribed, the figures prescribed in this connection being subject to a certain margin of tolerance. The minimum performance prescribed must be attained.

         1.4.3. Type-0 test with engine connected, service braking in accordance with paragraph 2. 1.1. (B) of this annex.

         1.4.3.1. The test shall be carried out with the engine connected, from the speed prescribed in paragraph 2.1.1. (B) of this annex. The minimum performance prescribed shall be attained. This test is not run if the maximum speed of the vehicle is < 125km/h.

         1.4.3.2. In addition, if the maximum speed of the vehicle is greater than 200km/h, a test is carried out at 80% of the maximum speed of the vehicle. The maximum practical performance figures shall be measured, and the behaviour of the vehicle shall be in accordance with paragraph 1.3.2. of this annex.

1.5. Type-I test (fade and recovery test)

1.5.1. Heating procedure

         1.5.1.1. The service brakes of all vehicles must be tested by successively applying and releasing the brakes a number of times, the vehicle being laden, in the conditions shown in the table below:
Conditions
v1 (km/h)         v2 (km/h)  delta t (sec)  n
80% v max  ≤ 120  1/2 v1     45             15

           where:

 v1 = initial speed, at beginning of braking
 v2 = speed at end of braking
 vmax = maximum speed of the vehicle
n = number of
