Mass' and using the general test conditions from ADR 38/...

       A.1.1.2.2  Brief periods of locking of the wheels are allowed, but stability must not be affected.

       A.1.1.3  In the event of failure of an 'Antilock System', the braking performance of the 'Service Brake System' and 'Emergency Brake System' must be maintained.

       A.1.1.4  The operation of an 'Antilock System' must not be adversely affected by magnetic or electric fields.

       A.1.1.5 The 'Control System' equipped with an 'Antilock System' must be shown to meet the requirements of clause 38.2.2.3 (actuation time) and clause 38.2.2.4 (release time) by testing in accordance with clause 38.3.11.3.

       A.2  INSTALLATION REQUIREMENTS

       A.2.1  an 'Antilock System' complying with clause A.1.1 must be fitted to:

       A.2.1.1  each 'Single Axle';

A.2.1.2  at least one 'Axle' in any 'Tandem Axle Group';

A.2.1.3  at least two 'Axles' in any 'Triaxle Group'.

       A.3  'ANTILOCK SYSTEM' ELECTRICAL SYSTEM.

       A.3.1.1  'Antilock Systems' must be powered by a 12V electrical supply system, through a connection to towing vehicle, using a connector conforming to DIN Standard 72570 configured for 12 volt operation.

       A.3.1.2  The connector must be wired to have the following functions :

       Pin 1 +ve high current trailer solenoid valve supply, 30 amps minimum rated capacity

       Pin 2 +ve low current trailer electronic unit supply, 4 amps minimum rated capacity

       Pin 3 -ve low current trailer electronic unit supply, 6 amps minimum rated capacity

       Pin 4 -ve high current trailer solenoid valve supply, 30 amps minimum rated capacity

       Pin 5 railer antilock failure, switched to -ve (e.g. pin 3 or pin 4) upon fault detection, 2 amps minimum rated capacity

       A.3.1.3  Any break in the supply of electricity to an 'Antilock System' and any electrical failure of an 'Antilock System' other than a failure of one or all of the electrical conductors between pins 3, 4 and 5 on the electrical connector and the antilock control module must be signalled to the towing vehicle by connecting Pin 5 on the electrical connector to –ve (ie pin 3 or pin 4).

       A.3.1.4  Each 'Antilock System' must connect pin 5 to -ve (e.g. pin 3 or pin 4) when initially energised and disconnect pin 5 from -ve at the latest when the trailer reaches a speed of 15 km/h and no defect is present.
