At the 58th GRB session, the expert from ETRTO introduced GRB-58-02, proposing new time measurement accuracy for instrumentation involved in the rolling resistance method (Annex 6 of the UN Regulation). The expert from the Russian Federation introduced GRB-58-13, arguing that this change of accuracy was not needed for Annex 6. This present revised proposal has been prepared the ETRTO and approved by Russia.
