See document GRB-65-25 for detailed explanation.

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.
