65.6.                                TEST OF ROAD SPEED LIMITATION

         This test is to determine the maximum road speed capability of vehicles.

         A vehicle representative of the vehicle type or a device representative of the road speed governor as appropriate shall meet these requirements.

65.6.1.                          Test Conditions
65.6.1.1.                    The settings of the test vehicle including the fuel feed, wheels and tyres, and transmission shall conform to the 'Manufacturer's' specifications;
65.6.1.2.                    the tyres shall be bedded and the pressures shall be as specified by the manufacturer;
65.6.1.3.                    the vehicle shall be at 'Unladen Mass';
65.6.1.4.                    the test track surface shall be free from standing water, snow or ice and shall be free from uneven patches and the gradient shall not exceed 2% and gradients shall not vary by more than 1% excluding camber effects; and
65.6.1.5.                    the mean wind road speed measured at a height at least 1 metre above the ground shall be less than 6 m/s with gusts not exceeding 10 m/s.
65.6.1.6.                    The instantaneous vehicle road speed shall be recorded throughout the test with a road speed measurement accuracy of at least ±1% at maximum time intervals of 0.1 seconds.
65.6.2.                          Acceleration Test Method
         Using the test conditions specified in clause 65.6.1, and starting from a road speed 10 km/h less that the 'Set Speed', the vehicle shall be accelerated as much as possible without changing gear by using a fully positive action on the accelerator control. This action shall be maintained without changing gear for at least 30 seconds after the 'Set Speed' is achieved.
65.6.3.                          Acceptance Criteria for Acceleration Test Method
65.6.3.1.                    With each gear which allows a theoretical maximum road speed above the 'Set Speed' engaged and when tested in accordance with Clause 65.6.2, within the first 10 seconds after reaching the 'Set Speed' the maximum vehicle road speed shall not exceed 105% of 'Set Speed' and the rate of change of vehicle road speed shall not exceed 0.5 m/s2 when measured over a time period greater than 0.1 seconds as shown in Figure 1.
65.6.3.2.                    With each gear which allows a theoretical maximum road speed above the 'Set Speed' engaged and when tested in accordance with clause 65.6.2 and more than 10 seconds after reaching the 'Set Speed', the maximum vehicle road speed shall not differ from the 'Set Speed' by more than ±3.3% of 'Set Speed', the maximum vehicle road speed shall not vary by more than 3.3% of the 'Set Speed' and the rate of change of road speed shall not exceed 0.2 m/s2 when measured over a time period greater than 0.1 seconds.
65.7.                                ALTERNATIVE STANDARDS
         Road speed governors complying with BS AU 217: Part 1 1987 "Maximum road
