greater than or equal to 400 kNm, need not be equipped with a 'Vehicle Stability Function'.
 1.                               Each vehicle required by clause 5.1.8 above to be equipped with a 'Vehicle Stability Function', must meet the requirements of APPENDIX 3.  Other vehicles may be certified to the requirements of APPENDIX 3, clauses 2 and 3, at the discretion of the 'Manufacturer'.
 2.                           All components and devices in the 'Brake System' must meet or exceed at least one appropriate and recognised international, national or association standard, where such standards exist, or the relevant parts thereof.  'Recognised' can be taken to include SA, SAE, BS, JIS, DIN, performance and design related ISO standards and UN regulations.
 3.                           Traction control systems may utilize part of the 'Service Brake System' provided that, except for parts common to both the traction control system and the 'Service Brake System', the traction control system or any failure of it cannot interfere with normal braking.
 4.                           In the case of a vehicle equipped to tow a trailer which uses air at a positive pressure:
          1.                              The pressure developed at full application of the 'Control' of the 'Service Brake System', must be between 650 kPa (1.0 'E') and 850 kPa (1.31 'E') at the coupling head of the pneumatic 'Control Line' and between 650 kPa and 900 kPa at the coupling head of the 'Supply Line', irrespective of the load condition of the vehicle.
          2.                              Where the vehicle is also equipped with an electric 'Control Line', full application of the control of the 'Service Brake System' must provide a digital demand value corresponding to a pressure between 650 kPa (1.0 'E') and 850 kPa (1.31 'E') (see ISO 11992:2003, including ISO 11992‑2:2003 and its Amd.1:2007).
          3.                              The pressure developed without any application of the 'Service Brake System', must be between 650 kPa and 900 kPa at the coupling head of the 'Supply Line'.
          4.                              The unladen vehicle must commence to develop a braking force on at least one 'Axle' of each 'Axle Group', before the 'Control Signal' at each 'Control Line' coupling reaches 0.154 'E' (100 kPa or the equivalent digital demand value in the case of any electric 'Control Line').
 1.                     The requirements of parts (a) to (c) of this clause must be demonstrated to be met through testing, including at any critical or worst case load condition, at the cut-in and cut-out pressures of the energy source, with a reservoir of 0.5 litre capacity connected to the pneumatic 'Control Line', the energy source stopped and the 'Supply Line' blocked off.
 2.                     For the purpose of part (d) of this clause, an 'Axle' is deemed to have commenced to develop a braking force, when the total static brake torque
