that the trailer 'Axle Loads' do not exceed the trailer 'Manufacturer's' nominated individual 'Axle Loads' ('GALR').

38.1.21.                      'Lightly Laden Test Mass' ('LLTM') is the mass of the trailer in its normal unladen condition.

38.1.22.                      'Normal Minimum Energy Level' is the normal operating minimum level of the energy storage devices as defined by the normal cut-in level of the storage charging system and in the case of a compressed air 'Brake  System', shall be taken as 650 kPa.

38.1.23.                      'Parking Brake System 38/00' - that part of the trailer 'Brake System' which is able to apply and maintain a restraining force at two or more trailer road wheels with and without the trailer being separated from the towing vehicle.

38.1.24.                      'S-Cam' means a foundation brake unit which utilises the rotation of an S-shaped cam to actuate the brakes.

38.1.25.                      'Service Brake System' the 'Brake System' which in proportion to the 'Control Signal', applies a restraining torque to the trailer wheels in normal operation.

38.1.26.                      'Skid Limit' - the degree of braking at which wheel lock-up commences.

38.1.27.                      Not used

38.1.28.                      'Stopping Distance/Time' - the distance/time from initial movement of the brake 'Control' to the trailer becoming stationary.

38.1.30.                      'Stored Fluid Energy' - energy stored as compressed air, in hydraulic accumulators, or as any form of electrical energy.

38.1.31.                      'Supply Line' means the path by which any 'Stored Energy' required to actuate/release the trailer 'Brakes' is supplied from the towing vehicle connection to the first other device in the trailer 'Brake System'.               (Normally referred to as the emergency line in a 2 line compressed air 'Brake System'.)

38.1.32.                      Not used

38.1.33.                      'Trailer Gross Axle Load Rating' (TGALR) - the sum of the 'GALR' of each 'Axle' attached to the trailer.

38.1.34.                      'Total Combination Mass' (TCM) - the combined mass of the laden or unladen trailer and the towing vehicle.

38.1.35.                      'Total Trailer Axle Load' (TTAL) is the total force exerted by the individual axles attached to the trailer when resting on a horizontal supporting plane.

38.1.36.                      'Unique' - a 'Unique' 'Brake System' is one consisting of a particular combination of components with particular physical and dimensional properties.

38.2.                                DESIGN REQUIREMENTS

         38.2.0  'Brake Systems' for trailers with an 'Aggregate Trailer Mass' of up to 4.5 tonnes.

         38.2.0.1  Every trailer shall be equipped with an efficient 'Brake System' which, with the exception of trailers equipped with over-run 'Brakes', shall be so designed as to be applied by the driver of the drawing vehicle from the driver's 'Seat' and, in the case of trailers with an 'Aggregate Trailer Mass' of greater than 2 tonne, operates on all wheels.

         38.2.0.2  The 'Brake System' on trailers with a 'Gross Trailer Mass' up to 2
