1.1.1.1. Where an ASLD is to be approved it shall be fitted by the manufacturer to a vehicle which is representative of the type for which the device is intended.

1.1.2. The settings of the engine of the test vehicle, particularly the fuel feed (carburettor or injection system), shall conform to the specifications of the vehicle manufacturer.

1.1.3. The tyres shall be bedded and the pressure shall be as specified by the manufacturer for the vehicle.

1.1.4. The vehicle mass shall be the minimum kerb weight declared by the manufacturer.

1.2. Characteristics of the test track

1.2.1. The test surface shall be suitable for enabling stabilised speed to be maintained and shall be free from uneven patches. Gradients shall not exceed 2 %.

1.2.2. The test surface shall be free from standing water, snow or ice.

1.3. Ambient weather conditions

1.3.1. The mean wind speed measured at a height of at least 1 m above the ground shall be less than 6 m/s with gusts not exceeding 10 m/s.

1.4. Test for the driver being informed that Vadj is being exceeded

1.4.1. The positive action (as referred to in paragraphs 5.2.5.4.1 and 21.2.5.4.1) required to enable Vadj to be exceeded shall be applied when the vehicle is running at a speed 10 km/h below Vadj.

1.4.2. The vehicle shall be accelerated up to a speed at least 10 km/h greater than Vadj.

1.4.3. This speed shall be maintained for at least 30 seconds.

1.4.4. Instantaneous vehicle speed shall be recorded during the test and measured with an accuracy of ±1 %.

1.4.5. The test shall be considered satisfactory if the following conditions are met:

1.4.5.1. The driver is informed by a warning signal when the actual speed of the vehicle is exceeding Vadj by more than 3 km/h.

1.4.5.2. The driver continues to be informed for the duration of the time that Vadj is exceeded by more than 3 km/h.

1.5. Test of the adjustable speed limitation function/device.

1.5.1. With the ASLF/D deactivated, for each gear ratio selected for the chosen test speed Vadj, the technical service shall measure the forces required on the accelerator control to maintain Vadj and a speed (Vadj*), which is 20 per cent or 20 km/h (whichever is the greater) faster than Vadj.

1.5.2. With the ASLF/D activated and set at Vadj, the vehicle shall be run at a speed of 10 km/h below Vadj. The vehicle shall then be accelerated by increasing the force on the accelerator control over a period of 1 s ± 0,2 s to that required to attain Vadj*. This force shall then be maintained for a period of at least 30 seconds, after the vehicle speed has stabilised.

1.5.3. The instantaneous vehicle speed shall be recorded during the test in order to establish the curve of the speed versus the time and during the operation of the ASLF/D as appropriate. The accuracy of the speed measurement shall be ±1 %. The accuracy of the time measurement shall be less than 0,1 s.

1.5.4. The test shall be considered satisfactory if the following conditions are met:

1.5.4.1. The stabilised speed (Vstab) reached by the vehicle shall not exceed Vadj by more than 3 km/h

1.5.4.1.1. After Vstab is reached for the first time:

1.5.4.1.1.1. Vmax shall not exceed Vstab by more than 5 %;

1.5.4.1.1.2. the rate of change of speed shall not exceed 0,5 m/s2 when measured over a period greater than 0,1 s;

1.5.4.1.1.3. the stabilised speed conditions specified in 1.5.4.1.1 shall be attained within 10 s of first reaching Vstab;

1.5.4.1.2. When stable speed control has been achieved:

1.5.4.1.2.1. speed shall not vary by more than 3 km/h of Vadj;

1.5.4.1.2.2. the rate of change of speed shall not exceed 0,2 m/s2 when measured over a period greater than 0,1 s;

1.5.4.1.2.3. Vstab is the average speed calculated for a minimum time interval of 20 seconds beginning 10 seconds after first reaching Vstab;

1.5.4.1.3. Tests in acceleration shall be carried out and the acceptance criteria verified for each gear ratio allowing in theory Vadj* to be achieved.
