Rules, this instrument sets out the extent or types of damage or corrosion, or repair of damage or corrosion, that will not prevent the holder of an AVV approval from verifying a road vehicle, or modifications of a road vehicle, under the approval.\n\n> Note: The holder of a RAW approval must also have regard to the limit of acceptable damage or corrosion in certain circumstances – see subsection 65(3) of the Rules.","sortOrder":3},{"sectionNumber":"5","sectionType":"section","heading":"Definitions","content":"#### 5 Definitions\n\n> Note 1: A number of expressions used in this instrument are defined in the Rules, including the following:\n\n    (a) approved Model Report;\n    (b) AVV approval;\n    (c) RAW approval.\n\n> Note 2: A number of expressions used in this instrument are defined in the Road Vehicle Standards Act 2018.\n\n  In this instrument:\n\n> body alignment test means a test to identify and assess distortion of a structural component of a vehicle, or distortion of the vehicle structure.\n\n> Note: Example: The body alignment test could involve measuring, and assessing the symmetry of, the vehicle.\n\n> dent does not include any bending of the sill seam of the vehicle.\n\n> flaking means corrosion of a metal surface of a vehicle that results in the separation of small and thin areas of the surface from the parent material.\n\n> Note: Flaking corrosion develops such that the flake primarily grows in area over time, spreading along the surface of the material.\n\n> pitting means highly localised corrosion of a metal surface of a vehicle that results in the formation of cavities or small blind holes in the material.\n\n> Note: Pitting develops such that each pit primarily grows in depth over time.\n\n> Rules means the Road Vehicle Standards Rules 2019.\n\n> structural component of a vehicle means any component intended to carry a load or force in the operation of the vehicle (including a load or force imposed as a result of a crash), other than components only used to support trim and lamps.\n\n> Note: Example: Door structures, hinges, latches, anchorages, airbag mounts and suspension mounts are examples of structural components.\n\n> vehicle structure means the parts of a vehicle that are integral to the vehicle, including the following:\n\n    (a) the vehicle chassis;\n    (b) the vehicle frame;\n

subsection (2), the following do not prevent the holder of an AVV approval from verifying a road vehicle, or modifications of a road vehicle, under the approval:\n    (a) one or more dents on the vehicle structure, or a structural component of the vehicle, of 25 millimetres or less in depth;\n    (b) distortion of a structural component of the vehicle, or distortion of the vehicle structure, where the difference in the length of corresponding diagonal lines, as ascertained through a body alignment test, is 10 millimetres or less;\n    (c) damage to or corrosion of a structural component of the vehicle, or of the vehicle structure, where:\n    (i) the damage or corrosion has been repaired by replacing damaged or corroded structural components with new components of the original specification; and\n    (ii) the repairs did not involve the cutting or welding of a structural component, or of the vehicle structure;\n    (d) variations in the gaps between panels greater than 5 millimetres, where:\n    (i) the variations are not the result of damage to the vehicle structure; and\n    (ii) if a body alignment test has not been conducted on the vehicle—a body alignment test would not be required under the Road Vehicle Standards (Verification of Road Vehicles) Determination 2021 by reason of the variations; and\n    (iii) if a body alignment test has been conducted on the vehicle—the difference in the length of corresponding diagonal lines, as ascertained through the test, is 5 millimetres or less;\n    (e) corrosion that has not resulted in flaking or pitting;\n    (f) alterations that amount to damage to a structural component of the vehicle, where:\n    (i) the alterations did not involve bending, distorting, heating the metal of, or drilling or cutting holes in, the structural component; or\n    (ii) the alterations consisted of modifications carried out in accordance with an approved Model Report that applied to the vehicle.\n\n> Note: Example 1: For paragraph (1)(e)—a vehicle has surface rust that has not resulted in flaking or pitting. This would not prevent the holder of an AVV approval from verifying the vehicle.\n\n> Note: Example 2: For paragraph (1)(f)—alterations have been made to a structural component of a vehicle. Those alterations amounted to damage to the component. However, the alterations did not involve bending, distorting, heating the metal of, or drilling or cutting holes in, the component. This would not prevent the holder of an AVV approval from verifying the vehicle, even though the modifications were not carried out in accordance with an approved Model Report that applied to the vehicle.\n\n> Note: Example 3: For paragraph (1)(f)—a vehicle has been subjected to alterations that involved drilling holes in a structural component. Those alterations amounted to damage to the component. However, the alterations consisted of modifications carried out in accordance with an approved Model Report that applied to the vehicle. This would not prevent the holder of an AVV approval from verifying the vehicle.\n\n  (2) Subsection (1) does not apply where the damage or corrosion, or repair of damage or corrosion, has resulted in:\n    (a) the splitting of a seam or joint between two panels; or\n    (b) the failure of a spot weld.\n\n> Note: Example: A road vehicle has sustained damage that resulted in dents to a structural component of 25 millimetres or less in depth, but also resulted in the failure of a spot weld. This level of damage would prevent the holder of an AVV approval from verifying the vehicle.\n\n  (3) The paragraphs of subsection (1) do not limit one another.\n\n> Note: Even if one paragraph of subsection (1) provides that damage or corrosion, or repair of damage or corrosion, of a certain kind or a certain extent does not prevent the holder of the AVV approval from verifying a road vehicle or modifications to a road vehicle, the approval-holder may still be prevented from verifying the vehicle or modifications if the type or extent of the damage or corrosion, or repair of damage or corrosion, exceeds the limit in another paragraph.","sortOrder":5}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":4,"scope_assessment":{"changed":false,"description":"The instrument remains tightly focused on its original purpose: establishing measurable limits for acceptable damage and corrosion for vehicle verification purposes.
