of gravity 100 mm above and 100 mm forward of the 'Seating Reference Point' (otherwise known as R Point) for each occupant seating position. It shall be fixed rigidly and securely so that it does not break away during J‑Turn testing.
                2.       An anthropomorphic ballast with dimensions in accordance with Figure 3 and a mass of 68 kg, shall be placed in each occupant seating position. This ballast shall be restrained using the 'Seatbelt Assembly' provided for each occupant seating position.

               FIGURE 3

               Dimensions for the anthropomorphic ballast
 1.                 If the simulated occupant loads result in the omnibus being loaded to less than its 'GVM', additional ballast is added to the omnibus in the following manner until the omnibus is loaded to its 'GVM' without exceeding any 'GALR': First, 7kg of ballast for each passenger is secured above each passenger where there is a luggage compartment else under the seat of each passenger; second, ballast is added to the lowest baggage compartment under the vehicle.
 1.                 If the simulated occupant loads result in the 'GALR' of any 'Axle' being exceeded or the 'GVM' of the omnibus being exceeded, simulated occupant loads shall be removed until the 'GVM' and each 'GALR' are no longer exceeded.
 1.                            Mass estimation cycle
     1.                     A mass estimation procedure for the 'Vehicle Stability Function' may be performed in accordance with the vehicle 'Manufacturer's' instructions.  This procedure may be repeated if an ignition cycle occurs or is needed at any time between the initiation and completion of the J-Turn test procedures prescribed in clause 6 of this annex.
 2.                            Tyre conditioning
     1.                     The tyres must be conditioned to wear away mould sheen and achieve operating temperature immediately before beginning the J-Turn tests.  The test vehicle shall be driven around a circle 45 ± 10 metres in radius at a speed that produces a 'Lateral Acceleration' of approximately 0.1g for two clockwise laps followed by two anti-clockwise laps.
 3.                            Brake burnishing
     1.                     The brakes may be burnished using any number of brake applications recommended by the vehicle 'Manufacturer'.  The brakes may be adjusted up to three times during the burnishing procedure, at intervals specified by the vehicle 'Manufacturer', and may be adjusted at the conclusion of the burnishing, in accordance with the vehicle 'Manufacturer's' recommendation.

 1.                                  Brake temperature conditioning and monitoring
     1.                            The individual brake temperatures must be between 66 °C and 204 °C for each J-Turn test prescribed in clause 6 of this annex.
     2.                            The brakes shall be warmed up to temperatures within the required 66 °C to 204 °C range by subjecting the vehicle to a number of sequential brake applications.
     3.                            If the temperature of any brake exceeds 204 °C during J-Turn testing, a
