1. This document presents an amendment to the extended mobility tyre (EMT) symbol following the detection of dimensional inconsistencies within the International Organization for Standardization Working Group (ISO) TC31/SC3/WG19, where the dimension "0,33h" was judged wrong and constituting an unnecessary over constraint. ISO experts agreed to correct the standard ISO 16992:2018 EMT symbol by removing such dimension and introducing the information that the two angles at the base are the same. This amendment is important to allow symbol implementation and to ensure no deviation from the requirement in reproducing it.


2. This document presents an amendment to the inflation value to be used for the tyre conditioning when assessing the "flat tyre running mode" of "run flat tyres" and of "extended mobility tyres". Indeed, as per ISO 16992:2018 this value shall not be speed dependant because the test performed for the "flat tyre running mode" is performed at constant speed irrespective of the tyre speed category. Therefore, the amendment is intended to ensure the harmonisation of this UN Regulation with the ISO standard and with other UN Regulations that may just refer to ISO 16992:2018 in setting their requirements. Also, the temperature sensor positioning requirements needs to be moved to paragraphs 3.7 and 4.7 in Annex 7 respectively for run flat and extended mobility tyres, because they address a testing parameter and not a conditioning value.
