85. The expert from Italy informed GRVA that he had submitted to the WP.29 secretariat in December 2021 a request for authorization to amend UN GTR No. 3, for consideration at the March 2022 session of AC.3. He detailed the technical matters to be addressed to harmonize UN Regulation No. 78 and UN GTR No. 3. He clarified that GRVA would be invited to consider introducing provisions for the activation of the stop lamp under regenerative braking and updating the references to ASTM standards to enable the use of the new ASTM standard reference test tyre F2493 for the measurement of the Peak Braking Coefficient (PBC). GRVA encouraged the expert from Italy to further discuss this item at the next AC.3 session. 86. GRVA agreed to keep GRVA-12-15 on the agenda as a reference document until its next GRVA session in May 2022. |
