7.1.                                    Kingpins that have a 'D-value' rating of greater than 40 kN must comply with and be installed to comply with the requirements of AS/NZS 4968.1:2003 Heavy-road vehicles – Mechanical coupling between articulated vehicle combinations – Design criteria and selection requirements for fifth wheel, kingpin and associated equipment[1]; and
7.1.1.                              AS/NZS 4968.3:2003 Heavy-road vehicles – Mechanical coupling between articulated vehicle combinations– Kingpins and associated equipment1.
7.1.2.                              The marking requirements of clause 12.4 may be used instead of those in AS/NZS 4968.1:2003.
7.2.                                    Kingpins that have a 'D-value' rating of 40 kN or less must meet clause 7.1; or
7.2.1.                              meet the static strength test requirements in clause 12.3.2 or the dynamic strength test requirements of clause 12.3.3; and
7.2.2.                              meet the marking requirements of clause 12.4 or of AS/NZS 4968.1:2003.
7.2.3.                              Where a kingpin has been tested to clause 12.3.3, it must be installed such that the installation will withstand a static longitudinally applied force equal to a minimum of the 'D-value' for 60 seconds duration without separation. This requirement may be demonstrated using 'Approved' calculations, where the calculations take into account both strength and fatigue resistance.
7.3.                                    'Skid-Plate' assemblies of 'Semi-Trailers' of TD category must comply with AS/NZS 4968.3:2003 and must be designed with provision for draining the water from the space above the 'Skid Plate'.
