in clause 7.15.1.1 below, allowance must be made for the effect of the increased rolling resistance resulting from the combination of vehicles being used to carry out the tests.
         1.                     Rolling resistance may be ignored for service brake laden effectiveness tests in accordance with Table 5 (Item 6A), where a single un-braked, flatbed 'Semi-trailer' with one 'Axle' only, a 'GALR' of at least 8,000 kg and a static load on its 'Axle' of at least 2,000 kg, is used.

 1.                                           PARTICULAR TEST CONDITIONS
     1.                                     Pre-test Instrumentation Check
         1.                               The number of decelerations for the purpose of instrumentation checks must not exceed 20.
         2.                               Such decelerations must be conducted from a speed of not more than 40 km/h and any instantaneous deceleration must not exceed 3 m/s2.
     2.                                     Service Brake Burnishing Procedure
         1.                               Burnishing, if conducted, consists of any desired number of decelerations to the 'Manufacturer's' recommendation.
         2.                               On completion of the burnishing procedure, if conducted, the brake system may be adjusted in accordance with the 'Manufacturer's' recommendation.
     3.                                     Service Brake Lightly Laden Effectiveness Test
         1.                               A series of tests must be conducted in the manner described in Table 1 (Item 3) or as an alternative in the case of a vehicle incorporating a compressed air 'Brake System', Table 5 (Item 3A).  The vehicle will be deemed to satisfy the requirements of this test, if all the parameters specified in the relevant Table are met in at least one test within a number of tests that must not exceed 6.
     4.                                     Lightly Laden Secondary Brake Test
         1.                               Where the secondary brake is not applied by the service brake 'Control', the vehicle must be decelerated using only the 'Secondary Brake System' and deemed to satisfy the requirements of this test, if all the parameters specified in Table 1 (Item 4) are met in at least one test within a number of tests that must not exceed 6.
         2.                               Where the secondary brake is applied by the service brake 'Control', the vehicle will be deemed to satisfy the requirements of this test if all the parameters specified in Table 1 (Item 4) or as an alternative in the case of a vehicle incorporating a compressed air 'Brake System', Table 5 (Item 4A), are met in at least one test within a number of tests that must not exceed 6 for each single failure of a fluid system, including where appropriate:
                  1.                              each sub-system of a 'Split Service Brake System'; and
                  2.                              failure of energy assistance in a 'Brake Power Assist Unit'.
     5.                                     Lightly Laden Partial Failure Test
         1.                               The requirements of this clause only applies to a vehicle fitted with a brake system where the secondary brake is applied by the service brake
