Based on the outcomes of a European Commission study, proposal to clarify the text and align its provisions with other vehicle sound regulations, especially UN R41, including to replace references to “two wheeled moped” with the term “L1 category vehicles” (and consequently to replace references to “moped” with “vehicle”) and to replace the term “noise” with “sound” (except for references to background noise) throughout the regulation. It proposes improved terminology and definitions, including new ones, improved sound emission testing conditions and procedures. It also introduces sound emission measurement through new testing of in use vehicles in motion.

Proposal to update the provisions of Regulation No. 92 to a level at least equivalent to the corresponding provisions in the European Union legislation. The document proposes improved terminology and definitions, including new ones, improved sound emission testing conditions and procedures. It also introduces anti-tampering provisions and an “Additional sound emission provisions” (ASEP) statement by the manufacturer.

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”, 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.

Proposal to clarify the text and align the provisions of UN R9 with other vehicle sound regulations, especially UN R41, pursuant to research conducted by the European Commission.

Proposal to refine the scope by replacing the phrase “can travel” by “can be propelled”. The use of “travel” in the scope can be interpreted to include vehicles using using electrical systems for purposes other than propulsion (e.g., energy recuperation) that fall outside the test conditions of UN R138.

Proposal to refine the scope by replacing the phrase “can travel” by “can be propelled”. The use of “travel” in the scope can be interpreted to include vehicles using using electrical systems for purposes other than propulsion (e.g., energy recuperation) that fall outside the test conditions of UN R138. The proposal further amends:

1. Paragraph 2.7. to make clear the “pause function” refers to systems that allow the driver to deactivate an AVAS system;
2. Paragraph 6.2.6.: The vehicle operator shall not deactivate AVAS while driving. However, the manufacturer shall be enabled to activate or deactivate AVAS, including automatically, by regional coding according to legal provisions of various markets.
3. Paragraph 11.: the transitional provisions were added according to the rules of WP.29 for new series of amendments. Paragraph 11.6. has been added to maintain approvals that also comply with the new series of amendments, as is the case for vehicles that do not have a pause function according to the newly suggested paragraph 6.2.6.
4. Annex 1, Addendum to the communication form No …, Technical Information: technical information regarding “Pause switch (yes/no)” will be no longer necessary.

Germany reviews problems with applying UN specifications for the marking of winter tyres, covering disparities in definitions and performance requirements across the tyre regulations (UN R30, R54, R75, R106, R108, R109 and R117). Therefore, Germany proposes that GRRF work to resolve these disparities and offers two possible solutions: 1) Introduce the definition of "Snow tyre for use in severe snow conditions” and the related performance and marking requirements established under UN R109 and R117 into UN R30, R54, R75, R108, and (possibly) R106; 2) Amending UN R117 to extend the scope of its snow performance criteria to additional tyre classes and categories, such as special tyres (POR, MPT), all terrain (AT) tyres, and retreaded tyres for passenger cars.

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 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 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 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 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.
