Proposal to increase the precision of the lane of travel measurements by extending to two digits after the decimal point and to designate the line DD’ for the end of the measurements. The introduction of the line DD’ would impact the minimum length of the section after the line BB’ to be coated per ISO 10844.

Proposal to increase the measurement precision by requiring measurement to the second decimal and to designate the line DD’ as the end point for measurements. The proposal also suggests editorial improvements and corrections.

Proposal to delete the proposed amendment to paragraph 6.2.3. of UN R51 which would limit the scope of the additional sound emissions provisions (ASEP) to M₁ and N₁ vehicles equipped with an internal combustion engine operational within the control range of Annex 7. Switzerland submits that the limitation would release manufacturers from responsibility for vehicle sound behavior outside of ASEP in contradiction to the historical interpretation that manufacturers are responsible for ensuring reasonable vehicle sound levels under all conditions, not only within ASEP.

Proposal to

1. harmonize the definitions of v_BB’ in UN R51
2. clarify the scope of Annex 1, Appendix 2, paragraph 5 by substituting “Running” for “Suspension” to describe the system addressed
3. clarify the procedures for particular cases under Annex 3.

Consolidation of draft amendments collected by OICA from various sources, including remarks of contracting parties during expert group meetings and meetings, and from discussions within the informal working group on ASEP. The document has been prepared to encourage discussion.
