a trailer is fitted with an auxiliary park brake release device, enabling stored energy actuation or release of any part of the 'Brake System' to be cut out, the device must be such that the 'Brake System' is restored to normal no later than on the resumption of the supply of 'Stored Energy' to the trailer from the towing vehicle.
6.9.                                    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 SAA, SAE, BS, JIS, DIN, ISO and ECE standards.
6.10.                                Brake line couplings must not be interchangeable and must be polarised. Couplings must comply with the requirements AS D8 - 1971, "Hose Couplings for use with Vacuum and Air-pressure Braking Systems on Prime-movers, Trailers and Semi-trailers" where applicable or alternatively Duomatic or compatible couplings may be used.
         Couplings must be configured as follows: Vacuum systems, 'Supply Line', female connector; Compressed air systems, 'Supply Line', male connector; or palm type with inboard interference lug: or Duomatic male connector, Part No. 452 804 0010 or equivalent.
6.11.                                Each air reservoir in a compressed air 'Brake System' must be fitted with a manual condensate drain valve at the lowest point. An automatic condensate valve may be fitted provided it also drains the lowest point. The manual drain valve may be incorporated in the automatic valve.
6.12.                                Each 'Brake System' must incorporate devices which compensate for any increased movement of its components arising from wear. Such devices must themselves contain provision for securing them throughout their working range in any position to which they may be adjusted to or to which they may themselves automatically adjust.
6.13.                                Each 'Brake System' must, when applied, produce a resultant braking force acting along the longitudinal centre line of the vehicle.
6.14.                                Where the 'Supply Line' supplies energy to devices other than 'Brake Power Unit 35/...' the design must be such that all the 'Brake Power Unit 35/...' are preferentially charged to an energy level of not less than 0.69 'E' (450 kpa).
6.15.                                The first call on the 'Stored Energy' must be that of the 'Brake System'.  Any other demand for 'Stored Energy' must be disconnected automatically if the 'Stored Energy' level falls below 0.69 'E' (450 kPa).
6.16.                                Where separate methods of actuation are provided for any of the functions of the 'Brake System', the actuation of one function must not cause the operation of another function.
6.17.                                ' Stored Energy' devices must be safeguarded to prevent depletion of the 'Stored Fluid Energy' through failure of any part of the supplying system.
6.18.                                In the case of
