UN R51 allows the use mechanical or electronic devices to control the gear shifting and measures to avoid accelerations greater than 2.0 m/s². However, the measures are not defined and the manufacturer or technical service is not obliged to document the methodology in the test report. This proposal would introduce a table with examples for devices and measures for reference and would require documentation of methodology used.

Pursuant to the GRB-67 discussions, OICA proposes to restrict the application of the partial load driving to pure electric vehicles in order to facilitate adoption of document GRB/2018/2 while allowing the ASEP informal group to further consider the proposed formulas for the ASEP anchor point.

Proposal to add indoor testing, including ISO 362-3, as an alternative to the type approval tests in Annex 3. In addition, UN R51 allows the use mechanical or electronic devices to control the gear shifting and measures to avoid accelerations greater than 2.0 m/s². However, the measures are not defined and the manufacturer or technical service is not obliged to document the methodology in the test report. This proposal introduces a table with examples for devices and measures for reference and would require documentation of methodology used.

Proposal by the Informal Working Group on Additional Sound Emission Provisions (ASEP) to introduce transitional provisions for Supplements 4 and 5 to the 03 series of amendments to UN R51 (in line with the transitional provisions of Supplement 3), to correct a reference and to clarify the requirements for stationary sound.

Proposal by the Informal Working Group on Additional Sound Emission Provisions (ASEP) to introduce a transitional provision in line with the transitional provisions of Supplement 3. The new transitional provision should be added to the text of draft Supplement 5 to the 03 series of amendments to UN R51 which was adopted by the Working Party on Noise at its sixty-eighth session (GRB/2018/10).

Proposal to address comments on the adopted Supplement 4:

1. align the flowchart in the appendix to Annex 3, Figure 3c with the amendment to paragraph 3.1.2.1.4.1 (c) of Supplement 3 to the 03 series
2. amend Appendix to Annex 3, Table 1 to limit to pure electric vehicles the options to either use mechanical or electronic devices to control the gear shift or take measures to avoid accelerations greater than 2.0 m/s² (GRB/2018/2 and GRB-67-17)
3. under Annex 7, paragraph 5.2., align the principle of testing between automatic and manual transmission having more than 5 gears.
