information to enable the setting of the device to be checked in service. The inlet pressure must be not less than 80 per cent of the maximum design inlet pressure, as declared by the trailer manufacturer.
         6.8.3.                              Where the 'Variable Proportioning Brake System' consists of a device controlled via the suspension of the trailer by any other means, any information to enable the setting of the device to be checked in service.
6.9.                                    Examples of markings that are in accordance with clause 6.8 for mechanically controlled devices and air pressure controlled devices in trailers fitted with a compressed air 'Brake System' are shown in APPENDIX 2.
6.10.                                A trailer need not be equipped with an 'Antilock System' and/or a 'Variable Proportioning Brake System' if;
6.10.1.                          a Converter Dolly'; and/or
6.10.2.                          fitted with an 'Axle Group' arrangement consisting of more than four tyres in a row of 'Axles' or more than four 'Axles' in an 'Axle Group'; and/or
6.10.3.                          it meets the unladen performance requirements of clause 6.5.2 without a 'Variable Proportioning Brake System' being fitted.
6.11.                                Where a trailer is not equipped with an 'Antilock System' and/or a 'Variable Proportioning Brake System' solely in accordance with clause 6.10.3, the information on the Vehicle Plate referred to in clause 8. of ADR 61/... must include the words "THIS VEHICLE IS NOT FITTED WITH ANTILOCK BRAKES OR VARIABLE PROPORTIONING BRAKES."
7.                                          EMERGENCY BRAKE SYSTEM
7.1.                                    Each 'Unique' trailer 'Emergency Brake System' must be shown by either test in accordance with part 9 and clause 13.1 or by the calculation based on data for 'Approved' components in part 18, to have an 'Established Retardation Co-efficient' of not less than 0.18 and to be able to sustain a 'Brake' force required to obtain an 'ERC' of 0.18 for a period not less than 15 minutes.
7.2.                                    The 'Emergency Brake System' may utilise parts of the 'Service Brake System' on the condition that any one failure of a 'Brake Device' in the 'Service Brake System' does not prevent the 'Emergency Brake System' from achieving its performance requirement. For the purpose of this Clause, the 'Brakes' and any mechanical linkage connected directly thereto, must be considered as not subject to failure.
7.3.                                    In the case of 'Semi-Trailers', when disconnected from the 'Prime-Mover', the failure of any structure designed to support the front of the trailer must not reduce the effectiveness of the 'Emergency Brake System' to less than half that required by clause 7.1.
7.4.                                    'Emergency Brake Systems' that employ 'Stored Fluid Energy' to hold them in the release position must be provided with an auxiliary release mechanism. The auxiliary device, control or tool, may rely on fluid energy stored within the trailer brake system, and
