95. The expert from Italy informed GRVA (GRVA-11-29) of their intention to submit a proposal for amendments to UN GTR No. 3 at the next session of Executive Committee of the 1998 Agreement (AC.3) that would propose to adapt UN GTR No. 3 to technical and standardization progress, 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). He asked for comments on that proposal. The expert from Canada explained that, in their view some further work would be needed, for example, on the definition proposed in para. 2.25. and other small items. |
