of part 6.
5.2.                                    The trailer 'Brake System' must be capable of being actuated from the towing vehicle by means of a connection between the trailer and towing vehicle with a performance not less than that specified for the 'Emergency Brake System' in part 7 after any one failure in a 'Brake Device' in the trailer 'Brake System'.
5.3.                                    A 'Parking Brake System 38/...' must be fitted and must meet the requirements of part 8.
5.4.                                    The trailer 'Brake System' must restrain the trailer automatically in the event of a trailer break-away with a performance not less than that specified for the 'Emergency Brake System' in part 7.
5.5.                                    A 'Brake System' which utilises 'Stored Energy' to actuate the 'Service Brake System' must be designed so that when the 'Supply Line' energy level is reduced at a rate of not less than 0.15E/sec (100 kPa/sec) the following conditions are met;
         5.5.1.                              the 'Brake System'  must not start to automatically apply the 'Brakes'  at a 'Supply Line'  energy level of more than 0.65 'E'  (420 kpa) and,
         5.5.2.                               the 'Brake System' must start to automatically apply the 'Brakes' at a 'Supply  Line' energy level not less than:
5.5.2.1.                        0.31  'E' (200 kPa) where the maximum braking effectiveness of the  'Brakes' so applied is dependent on  'Stored Fluid Energy' or;
5.5.2.2.                        0.24 'E' (155 kPa) where the maximum braking effectiveness of the 'Brakes' so applied is not dependent on  'Stored Fluid Energy' and;
5.5.2.3.                        with the  'Supply Line' energy level at 0.0  'E' the braking effectiveness must be at least that specified for the  'Emergency Brake System' in clause 7.1.
5.6.                                    The 'Brake System' must be designed so that no single failure in a 'Brake Device' in the 'Service Brake System', except of a 'Supply Line' or 'Control Line', shall cause the 'Brakes' to apply without a 'Control Signal' provided by the towing vehicle.
5.7.                                    Manual devices for the isolation of faulty devices or brake circuits may be included in the 'Brake System' but automatic devices of the type that normally remain passive and whose function cannot readily be checked during normal operation of the trailer are not permitted. For the purposes of this clause normal operation also includes the activity of coupling and uncoupling the trailer connections.
5.8.                                    Where 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.
5.9.                                    All components and devices in the 'Brake System' must meet or
