sensor system.

                  (b) The vehicle can undergo a sequence of brake activations in order to ensure the service brake system is bedded in prior to the test.

                  (c) 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°C prior to each test run.

              6.2.2.2. Details of the pre-test condition strategy requested by the vehicle manufacturer shall be identified and recorded in the vehicle type approval documentation.

              6.2.3. The mounted tyres shall be identified and recorded in the vehicle type approval documentation.

              6.3.  Test Targets

              6.3.1.  The target used for the vehicle detection tests shall be a regular high-volume series production passenger car of Category M1 AA saloon. or alternatively a "soft target" representative of such a vehicle in terms of its identification characteristics applicable to the sensor system of the AEBS under test according to ISO 19206-1:2018. The reference point for the location of the vehicle shall be the most rearward point on the centreline of the vehicle.

              6.3.2.  The target used for the pedestrian detection tests shall be a child "articulated soft target" and be representative of the human attributes applicable to the sensor system of the AEBS under test according to ISO 19206-2:2018.

              6.3.3.  Details that enable the target(s) to be specifically identified and reproduced shall be recorded in the vehicle type approval documentation.

              6.4.  Warning and Activation Test with a Stationary Vehicle Target

              6.4.1. The subject vehicle shall approach the stationary target in a straight line for at least two seconds prior to the functional part of the test with a subject vehicle to target centreline offset of not more than 0.2 m.

              Tests shall be conducted with a vehicle travelling at 20, 42 and 60 km/h (with a tolerance of +0/-2 km/h). If this is deemed justified, the technical service may test any other speeds listed in the tables in paragraph 5.2.1.4. and within the prescribed speed range as defined in paragraph 5.2.1.3.

               The functional part of the test shall start when the subject vehicle is travelling at a constant speed and is at a distance corresponding to a Time To Collision (TTC) of at least 4 seconds from the target.

               From the start of the functional part until the point of collision there shall be no adjustment to any control of the subject vehicle by the driver other than slight adjustments to the steering control to counteract any drifting.

              6.5.  Warning and Activation Test with a Moving Vehicle Target

               The subject vehicle and the moving target shall travel in a straight line, in the same direction, for at least two seconds
