Session 67 | Geneva | 24-26 Jan 2018
1. Adoption of the agenda
GRB/2018/1 | Annotated provisional agenda for the 67th (January 2018) GRB session
GRB-67-05 | GRB session general information and highlights from the November 2017 WP.29 session
2. Regulation No. 28 (Audible warning devices)
3. Regulation No. 41 (Noise emissions of motorcycles): Development
GRB-67-12 | UN R41: Proposal for amendments to the 04 series of amendments Proposal to clarify under para. 2.2.3 the conditions under which multiple exhaust versions’ results may be listed on a single R41 approval certificate. The current text may be strictly interpreted as requiring separate certification for every possible configuration, such as differences in exhaust systems, intakes or engine displacements. The proposal aims to improve efficiency and effectiveness of type approval procedures.
GRB-67-13 | Study on Euro 5 sound level limits of L-category vehicles: progress and CBA results
GRB-67-16/Rev.1 | IMMA comments on the EC Euro 5 L-Category vehicle sound level study
4. (a) Regulation No. 51 (Noise of M and N categories of vehicles): Development
GRB/2018/2 | Proposal for Supplement 4 to the 03 series of amendments to Regulation No. 51 UN R51 allows the use mechanical or electronic devices to control the gear shifting and measures to avoid accelerations greater than 2.0 m/s<sup>2</sup>. However, the measures are not defined and the manufacturer or technical service is not obliged to document the methodology in the test report. This proposal would introduce a table with examples for devices and measures for reference and would require documentation of methodology used.
GRB/2018/3 | Proposal for Supplement 4 to the 03 series of amendments to Regulation No. 51 Proposal including indoor testing as an alternative to type approval tests of Annex 3 to Regulation No. 51 including ISO 362-3.
GRB-67-07 | Suggestions for the development of UN R51
GRB-67-11 | Presentation on indoor pass-by noise testing
GRB-67-14 | UN R51: Proposal for a corrigendum to the draft Supplement 3 to the 03 series ASEP II informal group proposal to correct documents WP.29/2018/7 and GRB-67-06 regarding Supplement 3 to the 03 series of amendments to Regulation No. 51.
GRB-67-17 | UN R51: Proposal for amendments to GRB/2018/2 Pursuant to the GRB-67 discussions, OICA proposes to restrict the application of the partial load driving to pure electric vehicles in order to facilitate adoption of document GRB/2018/2 while allowing the ASEP informal group to further consider the proposed formulas for the ASEP anchor point.
GRB-67-01/Rev.1 | UN R51: Proposal for additional amendments regarding indoor test methods Proposal of amendments for inclusion with the proposals on indoor testing in document GRB/2018/3.
WP.29/2018/7 | UN R51: Proposal for Supplement 3 to the 03 series of amendments Extensive changes to UN R51 as developed mainly by the informal working group on Additional Sound Emission Provisions (ASEP II), but including further proposals submitted through GRB. All of these proposals were consolidated by GRB during its September 2017 session in Annex II to the session report. GRB intends to hold a final review of the changes, including whether they constitute a new series of amendments, during its January 2018 session, (i.e., prior to the March 2018 WP.29 session that will consider this document). The draft changes include proposals to<ol class="alpha"><li>amend the scope to be design-neutral and reflect the driving situations covered by the Regulation;</li><li>highlight that ASEP apply to vehicles and their electric sound enhancement systems such as the Audible Vehicle Alert System (AVAS) and silencers equipped with an active cancelling system</li><li>update the "backfire" assessment procedure; and</li><li>clarify the gear ratio anchor point in Annex 7 as defined via Annex 3</li><li>Paragraph 1: The scope was originally drafted for the Annex 3 test which refers to normal urban driving. A proposed additional sentence covers the intention of Annex 7.</li><li>Paragraph 2.8.1.: Adopt the wording from standard ISO 362-1:2015 for clarity. If an electric motor is not operational during the type approval tests, then its power must not contribute to the calculation of the power to mass ratio (PMR).</li><li>Paragraph 2.24., table: Amendments regarding paragraph of Annex 3 because paragraph is new. Amendments also for line BB’ to reflect that the measurement will not end after line BB’. For the speeds vAA’, vBB’ and vPP’, a wrong reference coming from ISO was corrected.</li><li>Paragraph 2.27.: A new definition of “kickdown” was introduced since this term is used in this Regulation. With a large variety of products, it is unclear what "kickdown" exactly means. This definition is a design neutral approach and reflects the intention of Annex 3 and Annex 7.</li><li>Paragraph 2.28.: Prevention of downshift is a legal measure to ensure that the vehicle can be tested within the test conditions as specified by this Regulation.</li><li>Paragraph 3.3.: Deletion of meaningless sentence given the requirement that the vehicles have to be loaded in order to be able to achieve the urban driving conditions as described in paragraph of Annex 3. The sentence has similarly already been deleted in Regulation (EU) No. 540/2014.</li><li>Paragraph 6.2.3.: Amend paragraph 11.6 to exempt vehicles with a serial hybrid drive train until July 2022 from ASEP since these vehicles do not have the internal combustion engine running within the control range of Annex 7 and therefore cannot yield valid test results.</li><li>Annex 1, Appendix 1: For the test method according to the pre-acceleration length may differ per gear ratio. In this case, it is necessary to report the pre-acceleration length per gear ratio.</li><li>Annex 1, Appendix 2: Missing elements of the information document have been added, namely "0.2. type" and "3.2.6. pressure charger(s)".</li><li>Annex 3, paragraph 2.1.: Lower temperatures will lead to slightly higher test results due to an increased tyre rolling sound. Thus, testing at lower temperatures will be a disadvantage for the manufacturer. If for practical reasons the manufacturer wishes to carry out tests at lower temperatures, this shall be accepted by the type approval authority.</li><li>Annex 3, paragraph 2.2.1.: For M1 and N1, the current provision has led to ambiguities about its meaning. The proposed new sentence clarifies the meaning. Further, the tolerances are broadened, as research shows, that the impact of the test mass can be neglected in a wide range. For M2, M3, N2 and N3, the current provision has led to ambiguities about its meaning. The proposed new sentence clarifies the meaning. If the test mass of the vehicle is equal to the target mass, the target mass shall be achieved with a tolerance of ±5 per cent according to equation (2) in paragraph of Annex 3. Consequently this has to be valid also for the test mass mt. If the test mass of the vehicle is lower than the target mass according to equation (12) and (13) in paragraph of Annex 3, the test mass shall be achieved with a tolerance of ±5 per cent. Concerning M2 and M3, for clarification and to avoid misunderstanding, the loading conditions for complete vehicles of category M2 (M > 3,500 kg) and M3 were aligned with the requirements for incomplete vehicles of category M2 (M > 3,500 kg) and M3. As a consequence, vehicles of category M2 (M ≤ 3,500 kg) have to be added to the table and their test mass requirement has to be aligned with those of vehicles of category M1 and N1.</li><li>Annex 3, paragraph 2.2.6.: add conditioning provisions for exhaust systems containing fibrous materials,</li><li>Annex 3, paragraph See the above justification for M2, M3, N2 and N3 in paragraph 2.2.1. </li><li>Annex 3, paragraph If a manufacturer does not produce vehicles with two axles only, he is not able to calculate the right test mass for his vehicles with more than two axles. For calculating the test mass, a vehicle with two axles has to be put on a scale to measure the unladen front axle load, mfa load unladen, and the unladen rear axle load, mra load unladen, for being able to calculate munladen as given in formula (3) of paragraph of Annex 3. In addition, a new paragraph provides a procedure for calculating the test mass of a virtual vehicles with two axles, based on an existing vehicle with more than two axles, when a vehicle with two axles is physically not available to be put on a scale.</li><li>Annex 3, paragraph Proposal to extend the measurement to a position where misfiring is detectable. A redundant sentence is deleted per paragraph 2.2.4.</li><li>Annex 3, paragraph Clarify gear usage where one gear ratio is above 2 m/s² and the other below a<sub>urban</sub>.</li><li>Annex 3, paragraph Clarify the proper setup for testing for vehicles with very short gear ratios.</li><li>Annex 3, paragraph Introduction of specifications for vehicles with only one gear ratio.</li><li>Annex 3, paragraph Simplify testing. With a fixed vehicle length, it is not necessary to adjust the test equipment (light barriers, pylons) for each vehicle.</li><li>Annex 3, paragraph Clarify the gear ratio selection procedures,</li><li>Annex 3, paragraph 3.2.3.: Reference correction</li><li>Annex 3, paragraph Reference correction</li><li>Annex 4, paragraph 1.: The performance of the fibrous material can be checked by completely removing the fibrous material. This reintroduces an option removed when Annex 5 of the 02 series of amendments was revised.</li><li>Annex 6, paragraph 2.1.: Proposal to simplify and clarify CoP. During the conformity of production procedures, neither the vehicle nor tyres will have a proper preconditioning. In many cases, the vehicles are foiled and parts may be missing as theft protection. It is very unlikely that the vehicles will have already the same performance as the type approval vehicle. This provision adopts the specifications from the revised ASEP provisions (Informal document GRB-65-26, Annex 7, para. 1). In addition, the range of masses was broadened in the same way as proposed for type approval. </li><li>Annex 6, paragraph 3.: Reference correction.</li></ol>
WP.29/2018/7/Add.1 | UN R51: Addendum to the proposal for Supplement 3 to the 03 series of amendments Proposal to include the following transitional provision, "Until 18 months after the date of entry into force of the Supplement 3, it shall not apply to extensions of existing approvals, originally granted prior to the date of entry into force of Supplement 3." This document was submitted after the WP.29 filing deadline in order to reflect recent developments. At its September 2017 session, GRB adopted a draft Supplement 3 to the 03 series of amendments to UN Regulation No. 51 and requested the secretariat to submit this proposal to the March 2018 session of WP.29. This was done in December 2017 (ECE/TRANS/WP.29/2018/7). At its next session in January 2018, GRB reviewed the proposal and decided to complement it with a new provision. The secretariat was requested to submit the modification as an addendum to the original WP.29 document (ECE/TRANS/WP.29/2018/7/Add.1).

WP.29/2017/107 | Draft General Guidelines for United Nations regulatory procedures and transitional provisions in UN Regulations Proposal from the IWVTA informal group to supersede the current guidelines for regulatory procedures and transitional provisions for UN Regulations (document WP.29/1044 and its Revision 1) with updated general guidelines for establishing or amending UN Regulations, including for the definition of scope, administrative and transitional provisions, use of alternative requirements, and cross-referencing with other regulations. This proposal aims to <ol class="alpha"><li>Streamline future work without superseding provisions of the 1958 Agreement and the existing UN Regulations,</li><li>Clarify rulemaking procedures pursuant to Revision 3 of the 1958 Agreement, and</li><li>Ensure "good regulatory practice" through clarifications to avoid divergence between the interpretation of Revision 3 and the application to UN Regulations.</li></ul>
GRB-67-09 | UN R138: Proposal for Supplement 2 to the 01 series of amendments Proposal to<ol class="alpha"><li>clarify that the speed range of 0-20 km/h applies to UN R138, but does not preclude the AVAS from operating a speeds above 20 km/h (para. 6.2);</li><li>delete subparagraphs under para. 6.2.6. that should have been removed when the 01 series of amendments prohibited driver-operated pause functions;</li><li>split the specifications for para. "2.2. Meteorological conditions" under Annex 3 to address indoor and outdoor testing separately for clarity and to avoid unnecessary requirements in each case.</li></ol>

GRB-67-02 | UN R92: Proposal for a Supplement 3 to the 01 series Proposal to introduce provisions for non-original replacement silencing systems (NORESS, independent aftermarket muffler systems) with multiple, manually or electronically adjustable, rider-selectable operating modes or variable geometries (NORESS with “flexibilities”). These "flexibilities enable the replacement systems to meet the requirements of Annex 3 (i.e., during testing) while producing much higher noise (sound pressure) outside the Annex 3 conditions. This amendment would require such NORESS to meet the ASEP requirements of UN R9 and UN R41. The amendment further introduces language taken from UN R51. In effect, NORESS with flexibilities performance under normal driving conditions would not be permitted to deviate from its performance under testing.
