Revised draft minutes posted on 21 January 2015.

The purpose of this proposal is to update the reference to the latest version of the ISO 10844 and to introduce transitional provisions for the shift of the test track requirements from ISO 10844: 1994 to ISO 10844: 2014. This proposal supersedes document GRB/2015/5.

Proposal to update and clarify the text of UN R28.

In response to concerns that approval agencies may not grant manufacturers the additional 1dB for L(wot) on conformity of production tests as changes had been made to Annex 6 of R41-04, GRB issued an interpretation recorded in the report of its 56th session. However, IMMA believes that industry and agency personnel may still not be aware of the interpretation. Therefore, IMMA proposes to codify the interpretation within UN R41.

Proposal to correct the Annex 7, paragraph 3.1. “Determination of the anchor point for each gear ratio” and a calculation symbol in paragraph 3.2.1 “Calculation of the slope of the regression line for each gear”.

Presentation of the benefits envisioned by the Netherlands from the use of AAA tyres.

Proposal from Japan, pursuant to the discussion of document GRB/2014/8 during the previous GRB session, to correct perceived inconsistencies in time measurement accuracy in annex 6.

Pursuant to the introduction of the deceleration method for measuring tire rolling resistance using the dω/dt approach (“Deceleration Calculator”) proposed by NAMI and accepted by GRB, UTAC (France) provides information on the results of tests conducted to confirm repeatability and reproducibility of the new method using different machines.

Draft proposal for minimum sound requirements (via an audible alerting signal) for low noise vehicles (e.g., electric vehicles).

Draft text that would allow the installation and use of a prescribed “pause button” for the temporary deactivation of an audible vehicle alerting system (AVAS) while prohibiting any other form of deactivation.

Proposal for an alternative to the proposal (document GRRF/2015/9) to restore transitional provisions incorrectly deleted by Supplement 6 to the 02 series of amendments.

This proposal is an alternative to that represented in document GRRF/2015/9 and GRRF-79-19.

The overall aim of the study is to propose policy options concerning the use of tyres for improvement of traffic safety. Centrally to this, is the idea that end users need to make the correct assessment in relation to the tyre condition in order to achieve a level of safety as high as possible. Within this context, the tyre condition is considered in relation to technical elements (tyre inflation pressure, tyre tread depth, tyre damage, tyre age, and meteorological influences) and one information element (driver awareness). The study addresses the topics of tyre usage and the impact on road safety (which are the potential safety improvements related to tyre usage from a technical perspective) and how can road users be supported to use tyres that have a better safety performance by policy options.

This document contains the consolidated text of proposals for the 03 series of
amendments to Regulation No. 51, as adopted by GRB at its sixtieth and sixty-first
sessions:
- ECE/TRANS/WP.29/GRB/58, para. 5, based on ECE/TRANS/WP.29/GRB/2014/5,
as amended by Annex III to ECE/TRANS/WP.29/GRB/58;1 and
- ECE/TRANS/WP.29/GRB/59, paras. 8-10, based on ECE/TRANS/WP.29/GRB/2015/3 and Corr.1, as amended by Annex III to ECE/TRANS/WP.29/GRB/59.

Following a decision of GRB, this consolidated text will be submitted to the June
2015 session of WP.29 for consideration and possible adoption.

Working draft version pursuant to the 3rd REG58-QRTV informal working group session.

Presentation on China’s international noise standards working group activities and program for future development of vehicle noise and silencing system durability requirements.

Correction of two minor reference errors contained in the proposal for Supplement 2 to the 04 series of amendments to Regulation No. 41 which was adopted during the March 2015 session of WP.29.

The current text of UN R41 provides an allowance that increases the noise limit value by 1 dB(A) for motorcycles tested only in second gear under Annex 3. This allowance expires on 1 January 2017. IMMA proposes to extend this allowance until 1 January 2018 in response to the delayed implementation of UN R41-04 in the EU (2016 instead of planned 2014).

Presentation on Japanese vehicle noise activities, including alignment with UN Regulations and subsequent abolition of certain current Japanese regulatory requirements (e.g. cruising noise, etc.).

Presentation of Japan’s plans for phasing in UN R41, UN R51 (Phase 2, but not Phase 3 limits), and UN R117 requirements.

Proposal to clarify the wording of the 03 series of amendments to UN R51 as adopted by the World Forum in June 2015 (document WP.29/2015/62). The adopted wording could lead to the interpretation that sound levels measured on the left side of the vehicle are mixed by calculation with sound levels measured on the right side of the vehicle. The proposed new wording clarifies that the overall sound emission is assessed individually per vehicle side.

Presentation on low-noise pavements and the PERSUADE (PoroElastic Road
SUrface for Avoiding Damage to the Environment) project.

At the GRB meeting in January 2015 the Netherlands introduced a justification and proposal for future tyre noise limits (document GRB-61-03). During the discussion, it was suggested to investigate whether difference in performance existed between Original Equipment Manufacturer (OEM) tyres and replacement tyres, noting that the transitional provisions in EC/661/2009 take into account the earlier introduction of noise limits of OEM tyres mounted on new vehicle types. Therefore, the Dutch Ministry of Infrastructure and the Environment asked M+P to investigate the statistics of tyre noise label values in OEM tyres in more detail.

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

Presentation in support of the proposal to increase the stringency of tyre noise limits from 1 November 2020.

Presentation by Dr. Edward C. Bell, Professional Development and Research Institute on Blindness, Louisiana Tech University.

Presentation supporting documents GRRF/2015/25, /29, and /32 proposing to:
a) Align definitions and content of UN tyre regulations;
b) Include a definition of “manufacturer” extracted from the resolution “R.E.3”;
c) Adopt a common definition and use of the terms “Manufacturer’s name”, “Brand name”, “Trademark”, “Trade description” and “Commercial name” and their links; and
d) Add information in the certificate to enable approval authorities to more easily understand the products the certificate addresses.

Paper describing the development and application of a method for determining benefits of tyre noise reduction efforts in terms of the number of people impacted.

Presentation on the Dutch-developed methodology for assessing the impact of changes to tyre and vehicle noise standards.

Document GRRF/2015/27 proposes to modify the marking requirements to replace PSI with kilopascals (“kPa”). The intent is to harmonize the pressure indication and avoid confusion between UN Regulation No. 54 and US FMVSS 119 or FMVSS 139. This proposal would allow for the use of kPa markings in place of PSI prior to the 1 January 2018 transition date.

Presentation of research conducted by the World Blind Union and National Federation of the Blind in the United States to validate the effectiveness of the proposed minimum sound levels for quiet vehicles at 10 and 20 km/h. The researchers concluded that the proposed sounds levels do not add significantly to the detectability of an approaching vehicle by a blind pedestrian and that internal combustion engine vehicles were detected substantially sooner than quiet vehicles equipped with the proposed acoustic vehicle alerting system (AVAS).

World Blind Union comments opposing the current provisions of the draft UN Regulation on quiet vehicle minimum sound levels, especially with regard to the effectiveness of the AVAS parameters, inclusion of “pause button”, and absence of stationary (“idling”) vehicle sound requirement.

Proposal to modify the marking requirements to replace PSI with kilopascals (“kPa”). The intent is to harmonize the pressure indication and avoid confusion between UN Regulation No. 54 and US FMVSS 119 or FMVSS 139. The proposal would also change the measurement units for drum speed from min^-1 to km.h^-1 in alignment with the requirements with other tyre regulations and align the wording in Annex 7, Appendix 1 with the text of the Regulation.

Proposal to:
a) Align definitions and content with the other tyre regulations (UN Regulations Nos. 30, 54, 75 etc.);
b) Include a definition of “manufacturer” extracted from the resolution “R.E.3”;
c) Adopt a common definition and use of the terms “Manufacturer’s name”, “Brand name”, “Trademark”, “Trade description” and “Commercial name” and their links; and
d) Add information in the certificate to enable approval authorities to more easily understand the products the certificate addresses.

Description of an accident wherein a blind person was killed by a truck backing up with its reverse-mode sound signal deactivated and of possible policy responses in Japan.

Proposal to update and clarify the regulation. The proposal refines definitions, removes the “AWD” abbeviation for “audible warning device” to avoid confusion with its more common use for “all wheel drive”, adds T category agricultural vehicles to the scope, modifies some administrative communications, and proposes three-direction acoustic measurements. The proposal also aims to structure the regulation to enable its application to additional sound warning devices not presently regulated at the international level, excluding acoustic vehicle alerting systems (AVAS) which will be subject to a separate regulation on minimum vehicle sound levels.

The EU established Regulation (EU) No 540/2014 concerning vehicle noise in 2014. This regulation includes provisions for acoustic vehicle alerting systems (AVAS) in Annex VIII. This document summarizes Commission objectives and plans with regard to the draft UN Regulation on this same subject.
