GRBP/2023/20 | UN R124: Proposal for a Supplement
Proposals:<ul><li>Para. 2.2.3.: Information related to construction materials is clarified.</li><li>Para. 2.2.4.: Deleted, since its content is covered by paragraph 2.2.8. in the proposed wording.</li><li>Para. 2.2.8.: The notion of the wheel geometric shape is clarified.</li><li>Para. 2.9.: The notion of defects caused by the production process is clarified. Only in the Russian language it is clarified that the crack propagation is actually a length and a depth of the crack. The proposed text makes it possible to distinguish between a crack that occurred during testing and a scratch, which may be an acceptable manufacturing defect.</li><li>Para. 3.1.2.13.: The technical description of the wheel is supplemented with information describing the product quality control in the production process.</li><li>Para. 5.1.6. and Annex 3: The application of optional marking is aimed at providing the consumers with information on the quality control of the manufactured wheel, as well as facilitating the selection of wheels with the required characteristics by consumers in case of providing with incomplete information on suitable vehicle types in accordance with paragraph 1.2. of Annex 10.</li><li>Annex 4, para. (а): The language of the provision is clarified.</li><li>Annex 4, paras. (b) and (d): Deleted, since the existing experience of testing confirms that the mechanical properties of the raw materials are not comparable with the mechanical properties of finished products (wheels). In this regard, there is no need to test the raw materials.</li><li>Annex 4, para. <notextile>(с)</notextile>: The list of critical zones on wheels where to take the material to check its characteristics is clarified. These critical zones shall be specified by the manufacturer in the application documentation, and they can also be specified by the technical service. A description of the characteristics of the material taken from paragraph (b) is provided, since this paragraph is deleted. Only in the Russian language the terms concerning the measured values have been changed.</li><li>Annex 4, para. (e): It is specified that the analysis of metallurgical defects is carried out in the most loaded spots of the wheels. These spots shall be specified by the manufacturer in the application documentation, and they can also be specified by the technical service. The analysis shall be carried out in comparison with the permissible defects specified by the manufacturer.</li><li>Annex 6: A recommendation is added to identify cracks occurred as a result of the test by using penetrating paints.</li><li>Annexes 7 and 8: The pressure drop in the tyre as a consequence of testing the wheel assembly with the tyre may not be due to damage to the wheel, but to damage to the tyre. To eliminate uncertainty in the interpretation of the test results, it is necessary to determine the cause of the tyre pressure drop. If the pressure drop in the tyre was caused by its damage, then it is necessary to carry out the tests again, using a new tyre.</li></ul>
