Correction to paragraph 6.2.2. “Sound level limits” to add a reference specifically to paragraph 3.1 of Annex 3 in order to ensure interpretation of the sound limit values as application only “noise in motion” and not to “stationary noise”. This aligns the 02 and 03 series texts.

Proposal to replace the use of metric “tonnes” with measurements in kilograms in the definitions of vehicle categories and mass.

Proposal including indoor testing as an alternative to type approval tests of Annex 3 to Regulation No. 51 in accordance with ISO 26101:2012 and ISO 362-3.

Presentation on the current European Commission draft proposal for the transposition of UN R138 regarding “quiet road transport vehicles” into EU law. The draft would require the audible alert signal to be activated at vehicle start-up, but would allow for use of a pause function activated by the driver. A fuller set of documents was provided for the 64th Technical Committee-Motor Vehicles session.

Proposal to pursue harmonization of reversing alarm requirements through the establishment of a new UN Regulation in order to promote safety and address noise concerns.

Proposal to clarify the text of the regulation, update provisions in line with Supplement 1 to the 02 series of amendments (WP.29/2015/64), and to align its provisions with those of UN R41 and R51, including:

1. replace the term “two wheeled moped” with “L₁ category vehicle”;
2. replace the term “moped” with “vehicle”;
3. replace the term “noise” by “sound” except for its use related to background noise;
4. replace “noise made by” with “sound emitted by”;
5. specify in each use of the term “speed” whether the reference is to engine speed or vehicle speed;
6. add definition for “rated engine speed” in addition to “rated maximum net power”;
7. add definitions for “reference mass” and “test mass”;
8. add definition for “maximum vehicle speed”;
9. add the words “or electronically” and “rider selectable” to paragraph 6.3.2. to cover electronically adjustable exhaust or silencing systems;
10. allow the use of in-motion testing in addition to stationary testing in Annex 1 and add the necessary data reporting provisions in Annex 3 similar to provisions under UN R41 04 series;
11. update references to ISO standards; and
12. add sub-paragraphs to Annex 3, paragraph 5.2. to hinder tampering.

Proposal for clarifications, including the applicability of certain provisions, in Annex 3: Methods and instruments for measuring the sound made by motor vehicles.

Proposal to correct Annex 3, paragraph 1.4.1. of the French version of the regulation to align with the original English text.

Presentation for discussion of specific technical questions concerning the application of UN 51 test procedures.

Draft proposal to incorporate provisions for reverse audible warning devices for [M2], [N2], N3 and M3 vehicles.

Presentation of Turkey’s proposals for revering audible warning devices, including provisions for multiple sound levels and pause functions.

Table prepared by the GRB chair of possible subjects for the future development of noise regulations.

Status report on the European Commission program to investigate the potential for new sound limits of L-category vehicles at Euro 5 step and make a justified proposal.

Additional materials covering task force topics and possible time frame for EC proposal on Euro 5 sound limits.

Netherlands proposal in response to the initiative from Germany and Japan to standardize and limit the sound emission from Reversing Alarms (documents 64-05, 64-06, 65-06 and 65-07) to amend the requirements, including the use a “white noise alarm” instead of a “tonal noise alarm”.

Proposal to delete category L₄ vehicles from the scope of the regulation. Motorcycles with a side car (L4 category vehicles) should be tested in a state that is designed to be operated on the road (i.e. the side car fitted to the vehicle) using the test procedures of UN Regulation No. 9. Since UN Regulation No. 41.04 does not cover motorcycles with a side car, this text should be deleted in order to avoid any potential misunderstandings.

Information on back-up accidents in Korea and proposal for scope and content of new requirements for reversing warning alarms.

Information on work in the Netherlands to implement noise-level labeling for roads (in a format similar to that used in Europe for labeling energy efficiency of household appliances).

Explanation of Netherlands interest in labeling of road surfaces, in particular as a means to encourage reductions in rolling resistance.

Paper presented at a Dutch Infra Congress 2016 held on 23 June 2016 concerning the potential benefits of a road labelling system.

Proposal to amend the wording of the transitional provisions as drafted for the 01 series to Regulation No. 138 (document WP.29/2017/7 for the March 2017 WP.29 session, prohibiting the AVAS pause function) with the guidelines for these provisions as established by Revision 3 of the 1958 Agreement.

Explanation of the proposals contained in documents GRB/2017/2 and GRB-65-26.

ASEP II informal group amendments to document GRB/2017/2. See document GRB-65-25 for additional explanations.

Presentation on legal requirements (push) and public education/incentivization (pull) strategies to decrease road noise levels. The presentation especially addresses the Dutch interest in a road labeling system for rating road surface noise levels.

Proposal to increase the stringency of tyre noise limits starting from 1 November 2020.

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 for a new working group to develop harmonized technical specifications, test procedures and performance requirements for audible warning systems that signal when a category M₃, N₂, or N₃ vehicle is moving in reverse gear.

Review of UN R41-04 limit-value application.

Proposal to exclude pure electric vehicles, including vehicles with auxiliary electric propulsion, from the scope of the regulation. This proposal has been submitted to complement WP.29/2017/4.

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 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.

Discussion of motorcycle and related vehicle noise issues, especially related to aftermarket modification (non-original replacement exhaust silencer systems (NORESS)).

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.

Presentation on the status of the European Commission-sponsored study to investigate the potential of and develop a proposal for new sound limits of L-category vehicles under Euro 5.

Presentation on the status of the transposition of UN R138 on Acoustic Vehicle Alerting System (AVAS) requirements for quiet (e.g., electric) vehicles into EU law. The European Commission expects publication of the new requirements in the October 2017 Official Journal. The Commission is working on the transposition of the 01 series of amendments (prohibiting driver-activated pause functions).

German authorities have carried out a study to assess the possibility for measuring UN R41.04-approved L category vehicles using typical “roadside check” equipment. The study found that such equipment provides a “lite” version of the UN 41.04 procedures that is useful in evaluating real-world performance. Germany intends to pursue a national “pass-by lite” test directive for UN R41-approved motorbikes and for non-original replacement exhaust silencer systems (NORESS) roadside and periodic technical inspections.
