have markings affixed in a visible position on the trailer in indelible form and containing the following information:
         6.8.1.                              Where the 'Variable Proportioning Brake System' consists of a device mechanically controlled by the suspension of the trailer, the useful travel (recommended units of mm) of the device between the positions corresponding to 'UTM' and 'GTM', as well as any further information to enable the setting of the device to be checked in service.
         6.8.2.                              Where the 'Variable Proportioning Brake System' consists of a device which modulates the air pressure in the brake transmission, the 'Axle' load(s) (recommended units of kg) corresponding to the 'UTM' and 'GTM' for the 'Axle(s)' which control(s) the device and the corresponding nominal inlet and outlet pressures (recommended units of kPa) of the device, as well as any further 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.
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
