Proposal to introduce corrections and clarifications to the 08 series of amendments.

Proposal to allow for an alternative process for electric energy consumption verification in Conformity of Production, and to amend the charger requirement and the measurement method of REESS current for a hybrid electric power train. Both changes align with procedures already included in 02 series of amendments to UN Regulation No. 154.

Proposal to extend the option from the 06 and 07 to the 05 series of amendments allowing the calculation of road load values from those determined according to UN GTR No.15 (WLTP).

Proposal for amendments to align UN R83 with UN R154 (WLTP).

Proposal to permit the use of hydrogen (H2) as fuel for emissions type-approval of heavy duty vehicles and to introduce an option to measure the total hydrocarbon (THC) emissions instead of measuring the non-methane hydrocarbon emissions in certain cases.

Final report on the development of amendments to improve measurement procedures and provide for alternative methods where needed.

Proposal for amendments concerning handling of vehicles not subject to normal use, vehicle-to-grid usage, procedures for verification of on-board monitors, and usable battery energy provisions.

Proposal to improve several aspects of the text with respect to signals measurement and accuracy, alternative measurement methods where needed, and other improvement to improve the robustness of the UN GTR.
