gradient in either direction by either :
9.6.1.                              test in accordance with part 10 and clause 15.1; or
9.6.2.                              test in accordance with part 10 and clause 15.2 ; or

10.                                      GENERAL PERFORMANCE ROAD TEST CONDITIONS
10.1.                                The ambient temperature at the test site must be greater than 0°C and less than 40°C.
10.2.                                All road tests must be conducted with tyres fitted of the size specified by the 'Manufacturer' as original equipment and must be inflated to pressures not less than those recommended by the 'Manufacturer'.
10.3.                                Braking tests must be carried out on approximately level surfaces.
10.3.1.                          Where the levels are unsurveyed, the test must be completed in both directions, the brakes being applied over the same section, and the two results averaged to determine the final result.
10.3.2.                          Where the difference in start and finish elevations for a brake test, expressed as a percentage of the 'Stopping Distance' , is known, the brake test need only be completed in one direction and the result corrected for any difference in elevation exceeding 1 percent.
10.4.                                The wind speed difference between two tests in opposite directions, or against the direction of travel in the case of a single brake test, must not exceed 15 km/h.
10.5.                                The towing vehicle used to facilitate the tests must be of a type normally employed to tow the particular trailer under test and must have enough power to attain the initial speed required for the specified braking tests.
10.6.                                All road tests must be conducted with the 'Axle Groups' loaded to 'GTM' and energy storage devices charged to 'Nominal Minimum Energy Level', unless otherwise required by this rule.
10.7.                                The test surface must be either concrete or bitumen pavement and must be free from loose material.
10.8.                                No towing vehicle braking system or other contrived means must contribute to braking effort and the towing vehicle engine must be declutched or neutral engaged, during the braking tests required by this rule.
10.9.                                The 'Brakes' may be burnished before conducting any effectiveness tests according to the brake manufacturer's recommended procedures.
10.10.                            The 'Brake System' must be adjusted in accordance with the brake manufacturer's recommendations before performance tests are conducted.
10.11.                            The performance requirements must be met with no deviation of the vehicle from its course greater than 300 millimetres.
10.12.                            No part of the 'Brake System' must exceed 100°C immediately prior to the commencement of a brake test sequence.
11.                                      SERVICE BRAKE EFFECTIVENESS TEST CONDITIONS
11.1.                                The initial speed at the point where trailer braking commences must be:
11.1.1.                          for trailers having a 'Aggregate Trailer Mass' up to 45 tonnes and
