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.

Draft presentation on the amendments developed by the informal working group on Additional Sound Emission Provisions.

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”.

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

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.

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.

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.

Updated version of document GRB/2017/2 pursuant to discussions during the 2nd ASEP II informal group session.

OICA proposal to provide a clearer and more precise definition for “stable acceleration”. The definition introduced in document GRB/2017/02 is specified as "when the acceleration from line AA’ to PP’ has a low variation to the acceleration from line PP’ to BB’.” The term “low variation” is imprecise and so OICA proposes the wording “when the acceleration ratio a_{(PP’-BB’)}/a_{(AA’-BB’)} is lower than 1,2.”

Discussion of current issues related to vehicle noise levels, especially given the availability of affordable electronic devices that enable car owners to artificially increase vehicle sound output.

Presentation of concerns and possible responses through GRB regarding vehicle noise, especially related to system tampering and vehicle modifications.

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.

Presentation updated to include revisions to the working document GRB/2017/2 as agreed during the 2nd ASEP II informal group session to be presented during GRB-65 as an informal document amending the draft Supplement 2 to the 03 series of amendments to UN R51.
