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

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.

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

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 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.

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.

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

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

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 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 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 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.

Addendum to integrate agenda items taken over from GRRF following its “conversion” into GRVA.

ASEP informal group report on the effort to provide clarification and guidance on the interpretation and application of paragraph 6.2.3. last sentence of UN R51.03 (“The sound emission of the vehicle under typical on-road driving conditions, which are different from those under which the type-approval test set out in Annex 3 and Annex 7 was carried out, shall not deviate from the test result in a significant manner.”)

Proposal to update the original authorization pursuant to the transfer of responsibility for tyre regulations from GRRF (now GRVA) to GRB (expected to become GRBP).

Proposal to

1. exempt hybrid vehicles that do not provide valid test results (e.g., internal combustion engine active under test conditions)
2. clarify the text concerning permissible AVAS operating conditions
to differentiate indoor and outdoor facility requirements (e.g., weather station requirement) and
3. update flowcharts in Annex 3 in line with text.

Proposal to align ASEP for high powered L₄ and L₅ vehicles, used for passenger transport, is proposed in line with UN Regulation No 41.04 due to comparable sound emissions levels of L₄ and L₅ vehicles with the ones of L₃ vehicles and the possibility of applying similar measurement methods for sound emissions for those vehicle categories. This is also supported by the Commission study on enhanced sound requirements for mopeds, quads and replacement silencers of L-category vehicles which resulted in amendments to UN Regulation Nos 9, 63 and 92 (ref. document WP.29/2017/2).

Proposal to align UN R117 related to approval numbers and markings in line with the provisions of Schedule 4 to the 1958 Agreement addressing the concern raised by the Informal Working Group on the
International Whole Vehicle Type Approval (IWVTA).

Status after the 19th IWG Meeting (Geneva, 11-12 September 2018)

Presentation regarding the the national regulation in the Netherlands on delivery noise of trucks.

Presentation in support of establishing a 02 series of amendments to UN R117 with higher stringencies based on informal document GRB-66-03.

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 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 (IWG) on Additional Sound Emission Provisions (ASEP) to introduce transitional provisions in line with the transitional provisions in Supplement 3 and to reintroduce a sentence deleted by mistake in Supplement 4 to the 03 series of amendments to UN Regulation No. 51.

Proposal by the Informal Working Group (IWG) on Additional Sound Emission Provisions (ASEP) to correct a reference in Supplement 3 to the 03 series of amendments to UN R51.

Proposal to clarify the identification, marking and test provisions applicable to tyres designed for speeds above 240 km/h.

Proposal to introduce provisions for “worn tyre” thresholds and test procedures.

Proposal to ensure that that P-type tyres can be distinguished from non-P-type tyres.

Proposal to introduce two extra stages with limits (stage 3 and stage 4) for the rolling sound emission, wet grip performance and rolling resistance coefficient. (Stage 2 for wet grip performance is omitted intentionally in this proposal.)

Proposal to align the provisions of UN R117 regarding approval numbers and markings with the provisions of Schedule 4 to the revised 1958 Agreement.
