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.
5.9.                                    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 SA, SAE, BS, JIS, DIN, performance and design related ISO and UNECE standards.
5.10.                                Brake line couplings must not be interchangeable and must be polarised. Couplings must comply with the requirements – AS 4945:2000, 'Commercial road vehicle – Interchangeable quick release couplings for use with air-pressure braking systems' where applicable or compatible couplings which meet the requirements of ISO 1728:2006 'Road vehicles – Pneumatic Braking connections between motor vehicles and towed vehicles – Interchangeability' may be used.
5.11.                                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.
5.12.                                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.  Where a trailer is equipped with an 'Antilock System', such devices must be automatic.
5.13.                                Except for braking systems capable of producing asymmetric braking in response to prevailing tractive conditions, each 'Brake System' must, when applied, produce a resultant braking force acting along the longitudinal centre line of the vehicle.
5.14.                                Where the  'Supply Line' supplies energy to devices other than  'Brake Power Unit 35/...' including spring brakes, the design must be such that all the 'Brake Power Unit 35/...' are preferentially charged until the supply line reaches  an energy level of not less than 0.69 'E' (450 kpa); or
         5.14.1.                           the spring brakes must not release before there is sufficient pressure in the service air tank to allow application of a service brake to at least the emergency ERC as required by clause 7.1.
         5.14.2.                           Systems that utilize spring brakes for emergency and parking brakes are deemed to comply with this requirement if the parking/emergency brakes do not release until a service tank pressure of 0.435 'E' (283 kPa) is reached .
         5.14.3.                           Spring brake release is deemed to occur when the brake friction materials cease to contact.
5.15.                                The first call on the 'Stored Energy' must be that of
