attachments provided on the 'Towbar' for the safety chain(s), each attachment including the safety chain(s) must withstand the following forces without any residual deformation that must interfere with or degrade the function of the assembly, nor shall there be any breaks, cracks, or separation of components:
6.2.1.1.                        longitudinal tension - the 'Towbar's' rated capacity; and
6.2.1.2.                        vertical load - 0.5 × the 'Towbar's' rated capacity.
6.3.                                    Marking
6.3.1.                              Except where the 'Towbar' is an integral part of the vehicle the 'Towbar' must clearly and permanently display the following information:
6.3.1.1.                        the 'Towbar' manufacturer's name or trade mark;
6.3.1.2.                        the "make and model" shown on the 'Compliance Plate' fitted to the vehicle for which it is designed or the manufacturer's part number; and
6.3.1.3.                        its maximum rated capacity expressed in kilograms in numerals not less than 2.5 mm high. The maximum rated capacity must be the 'Aggregate Trailer Mass' for which the 'Towbar' is designed and must not exceed the motor vehicle manufacturer's recommendation.
6.3.2.                              Where the information required in clause 6.3.1 is not visible when the 'Towbar' is fitted to the vehicle a plate must be affixed to the vehicle adjacent to the 'Towbar' showing the maximum rated capacity of the 'Towbar'.
7.                                          DRAWBAR REQUIREMENTS
7.1.                                    The 'Drawbar' must withstand the following forces applied at the centreline of the intended 'Coupling' without incurring loss of attachment or any distortion or failure which will affect the safe drawing of the towed trailer:
7.1.1.                              longitudinal tension and compression - 1.5 × the 'Aggregate Trailer Mass';
7.1.2.                              transverse thrust - 0.5 × the 'Aggregate Trailer Mass'; and
7.1.3.                              vertical tension and compression - for rigid 'Drawbar' trailers 0.5 × the 'Aggregate Trailer Mass'.
7.2.                                    The 'Drawbar' must be securely attached to a substantial portion of the towed trailer.
7.3.                                    When a safety chain(s) is fitted, each attachment must be of sufficient strength to withstand the forces imposed.
7.3.1.                              To establish the strength of the attachments provided on the 'Drawbar', the attachments including the safety chain(s) must withstand the following forces without failure:
7.3.1.1.                        longitudinal tension - the 'Aggregate Trailer Mass'; and
7.3.1.2.                        vertical load - 0.5 × the 'Aggregate Trailer Mass'.
8.                                          SAFETY CHAIN(S)
8.1.                                    There must be affixed to a substantial portion on every trailer which is not fitted with an 'Emergency Brake System' in accordance with the Australian Design Rule 38/... "Trailer Brake Systems", and on every rigid 'Drawbar' 'Pig Trailer' except a 'Converter Dolly', a safety chain(s) which will hold in tow the trailer in the event of failure or accidental detachment of the 'Coupling'.
8.2.                                    A rigid 'Drawbar' 'Pig Trailer' which has a 'Aggregate Trailer Mass' of 2.5 tonnes or more must be fitted with 2 safety chains for
