Proposal to introduce provisions for non-original replacement silencing systems (NORESS, independent aftermarket muffler systems) with multiple, manually or electronically adjustable, rider-selectable operating modes or variable geometries (NORESS with “flexibilities”). These "flexibilities enable the replacement systems to meet the requirements of Annex 3 (i.e., during testing) while producing much higher noise (sound pressure) outside the Annex 3 conditions. This amendment would require such NORESS to meet the ASEP requirements of UN R9 and UN R41. The amendment further introduces language taken from UN R51. In effect, NORESS with flexibilities performance under normal driving conditions would not be permitted to deviate from its performance under testing.

Presentation in support of Germany’s proposal for amendments to UN R92 on non-original replacement exhaust silencing systems.

Proposal for amendments to introduce ASEP requirements for L4 and L5 category vehicles with PMR > 50 W/kg.

Proposal to

1. clarify that the speed range of 0-20 km/h applies to UN R138, but does not preclude the AVAS from operating a speeds above 20 km/h (para. 6.2);
2. delete subparagraphs under para. 6.2.6. that should have been removed when the 01 series of amendments prohibited driver-operated pause functions;
3. split the specifications for para. “2.2. Meteorological conditions” under Annex 3 to address indoor and outdoor testing separately for clarity and to avoid unnecessary requirements in each case.

Proposal to clarify under para. 2.2.3 the conditions under which multiple exhaust versions’ results may be listed on a single R41 approval certificate. The current text may be strictly interpreted as requiring separate certification for every possible configuration, such as differences in exhaust systems, intakes or engine displacements. The proposal aims to improve efficiency and effectiveness of type approval procedures.

ASEP II informal group proposal to correct documents WP.29/2018/7 and GRB-67-06 regarding Supplement 3 to the 03 series of amendments to Regulation No. 51.

Proposal of amendments for inclusion with the proposals on indoor testing in document GRB/2018/3.

Presentation on a Dutch project for the labeling/rating of road surfaces for noise, wet skid resistance, rolling resistance, and lifespan.

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 introduce requirements for non-original replacement exhaust silencing systems with multiple, manually or electronically adjustable, rider-selectable operating modes or variable geometries (NORESS with “flexibilities”). This is a consolidated version of the amended regulation with the changes marked in bold and strikethrough text.

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.

Proposal for amendments to introduce ASEP requirements for L4 and L5 category vehicles with PMR > 50 W/kg.

In informal document GRB-66-12, Germany suggested making ASEP testing mandatory under UN R41.
This proposal from IMMA amends UN R41 towards the application of ASEP test procedures.
