GRRF/2018/1 | Provisional agenda for the 86th GRRF session

GRRF/2018/1/Add.1 | GRRF: Annotated provisional agenda for the 86th (February 2018) session

GRRF-86-01 | GRRF: Running order of the agenda for the 86th (January 2018 session)

GRRF-86-08 | General information for the February 2018 GRRF session

GRRF-86-27 | GRRF-86: Updated and consolidated provisional agenda Session agenda updated pursuant to the latest informal document submissions.

GRRF-86-12 | Light Vehicle AEBS informal group: Report on the 2nd session Report on the development of AEBS requirements for light vehicles, including a note on the intention to seek GRRF approval for a new regulation on M₁/N₁ vehicle AEBS separate from the current UN R131 on heavy-duty vehicle AEBS.

GRRF-86-18 | UN R131: Proposal to amend document GRRF/2017/24 OICA counter-proposal to address the German concern over manual deactivations of AEB systems. The original document (GRRF/2017/24) proposed automatic reactivation of the AEBS when the vehicle speed exceeds 30 km/h. OICA proposes reactivation after 15 minutes of continuous operation at a speed above 70 km/h.

GRRF-86-32 | UN R131: Proposal to amend document GRRF/2017/24 Germany proposed, in document GRRF/2017/24, to require automatic reactivation of a manually deactivated automatic braking system. One concern with the proposal invoked the need for prolonged deactivation under certain circumstances, such as when a vehicle is fitted temporarily with a snow plow. This proposal would explicitly require AEBS to be capable of detecting a blocked sensor (already implicit in the regulation) such that AEBS would not reactivate in such cases.

GRRF/2017/24 | Proposal for amendments to Regulation No. 131 Proposal to restrict manual deactivation of AEB systems to speeds under 30 km/h. The proposal would require automatic reactivation of the AEBS when the vehicle speed exceeds 30 km/h.

GRRF-86-32 | UN R131: Proposal to amend document GRRF/2017/24 Germany proposed, in document GRRF/2017/24, to require automatic reactivation of a manually deactivated automatic braking system. One concern with the proposal invoked the need for prolonged deactivation under certain circumstances, such as when a vehicle is fitted temporarily with a snow plow. This proposal would explicitly require AEBS to be capable of detecting a blocked sensor (already implicit in the regulation) such that AEBS would not reactivate in such cases.

GRRF-86-18 | UN R131: Proposal to amend document GRRF/2017/24 OICA counter-proposal to address the German concern over manual deactivations of AEB systems. The original document (GRRF/2017/24) proposed automatic reactivation of the AEBS when the vehicle speed exceeds 30 km/h. OICA proposes reactivation after 15 minutes of continuous operation at a speed above 70 km/h.

GRRF/2018/2 | Proposal for a Supplement to Regulation No. 139 Proposal to clarify the purpose of UN R139 which was originally established through the extraction of brake assist system (BAS) provisions from UN R13-H on brake systems. Within the context of UN R13-H, the BAS provisions were written to assess performance in cases where a vehicle was fitted with a brake assist system. As a stand-alone regulation, UN R139 applies only to vehicles that are equipped with BAS. Therefore, this supplement proposes to refine the text to remove the "if fitted" language and ensure that UN R139 can only be applied to a vehicle equipped with a BAS.

GRRF/2018/3 | Proposal for a Supplement to Regulation No. 140 Proposal to remove “if fitted” language from the text to clarify that UN R140 can only be applied to a vehicle equipped with a ESC system. UN R140 was originally established through the extraction of electronic stability controls (ESC) provisions from UN R13-H on brake systems. Within the context of UN R13-H, the ESC provisions were written to assess performance in cases where a vehicle was fitted with an electronic stability control system. As a stand-alone regulation, however, UN R140 applies only to vehicles that are equipped with ESC. The proposal also would correct an apparent error in to Annex 4, paragraph 2.1. where the reference to "ISO 15037 Part 1:2005" should read "ISO 15037 Part 1:2006".

GRRF-86-16 | UN R13 and 13-H: Proposal for amendments to the 01 series of amendments This document presents two proposals. (1)The new series 02 of Regulation 79 introduced requirements for RCP (remote controlled parking) systems. An RCP system requires the engagement of an EPB (electronic parking brake) once the manoeuvre has finished and the ignition is switched off. This proposal would allow the release or disconnection of the EPB by a remote control system (approved to R79) so the RCP can subsequently drive the vehicle out of a parking spot. (2) Proposal to permit illumination of the stop lamp for electric regenerative braking under 0.7m/s² deceleration in order to allow for "one-pedal driving" of electric vehicles.

GRRF-86-33 | UN R13: Proposal for a Corrigendum to Revisions 7 and 8 Revision 7 of Regulation No. 13 includes a former version of Figure 1B which was changed with Amend 4 to Revision 6 of UN Regulation No. 13. This correction is also needed for Revision 8, which contains the same error.

GRRF-86-16/Rev.1 | UN R13 and 13-H: Proposal for amendments to the 01 series of amendments Revised proposal concerning remote-controlled parking (RCP). The new series 02 of Regulation 79 introduced requirements for RCP systems. An RCP system requires the engagement of an EPB (electronic parking brake) once the manoeuvre has finished and the ignition is switched off. This proposal would allow the release or disconnection of the EPB by a remote control system (approved to R79) so the RCP can subsequently drive the vehicle out of a parking spot. The second proposal in the original document concerning regenerative braking and stop lamp activation will be discussed again as a revised formal document at the September 2018 GRRF session.

GRRF/2013/13 | Proposal for collective amendments - Regulation Nos. 13, 13-H, 79, 89, and the LDWS and AEBS regulations Proposal for collective amendments of amendments to Regulations Nos. 13 (Heavy vehicle braking), 13-H (Brakes of M1 and N1 vehicles), 79 (Steering equipment) and 89 (Speed limitation devices) and the new Regulations on LDWS and AEBS to clarify the references to Regulation No. 10 into the UN Regulations mentioned above.

GRRF/2018/4 | Proposal for a new Regulation on agricultural vehicle couplings Formal proposal from the ACDC informal group for consideration by GRRF for a new Regulation on uniform provisions concerning the approval of mechanical coupling components of combinations of agricultural vehicles.

GRRF-86-03 | UN R55: Proposal for amendments Proposal to correct Revision 2 of UN R55 to align with the text of Supplement 04 to 01 series of amendments. This proposal removes a subparagraph under paragraph 13.1 that should not have been included in the Revision.

GRRF-86-06 | Status report of the ACDC informal group Report of the expert group on agricultural coupling devices and components on the development of a new UN Regulation.

GRRF-86-34 | UN R55: Draft proposal for a new supplement to the 01 series of amendments Annex 1 of UN R55 concerns the type approval communication form. Item 9.3. requires information "For Class A mechanical coupling devices or components, including towing brackets". Poland proposes to add "if fitted" to the description in order to avoid interpretations that brackets must be part of the approval (i.e., the approval may concern the coupling ball without additional attachments).

GRRF-86-02 | Agricultural vehicle couplings: Introduction of the proposed new regulation

GRRF-86-10 | GTR 3: Revised proposal for Amendment 3 Revised proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78 while addressing its use under self-certification compliance systems.

GRRF/2017/14 | Proposal for amendments to the 04 series of amendments to Regulation No. 78 Regulation No. 53 currently allows for the activation of the stop lamp by application of the brakes only. As already presented at a session of the Working Party on Lighting and Light-Signalling (GRE) (see ECE/TRANS/WP29/GRE/2015/42), IMMA is proposing to introduce the activation of stop lamps under more conditions than the application of the service brake only, e.g. also by regenerative braking. As noted in the report of seventy-fourth session of GRE, see ECE/TRANS/WP29/GRE/74, para. 30: "the proposal might need to be accompanied by a modification of Regulation No. 78 under GRRF." Therefore, IMMA has prepared this proposal for Regulation No. 78. A revised corresponding proposal on Regulation No. 53 will also be submitted to the October 2017 session of GRE.

GRRF-86-11 | GTR 3: Revised report on Amendment 3 Revised technical report to accompany the proposal for amendment 3 (concerning mainly ABS issues) to GTR 3.

GRRF/2017/15 | Proposal to amend Global Technical Regulation No. 3 Proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78 while addressing its use under self-certification compliance systems.

GRRF-86-35 | UN R78: Proposal for amendments Updated version of document GRRF/2017/14 to amend UN R78 with regard to stop lamp activation. IMMA has proposed (document GRE/2015/42) to allow stop lamp activation under UN R53 through means other than application of the brakes (e.g., by electric vehicle regenerative braking). This proposal accordingly amends UN R78 regarding generation of the brake signal.

GRRF-86-37 | UN R90: Presentation highlighting cost concerns with the new 1958 Agreement approval numbering system CLEPA presentation on the type approval process for replacement brake pads, linings, and drums and the impact of the new approval numbering system adopted under Revision 3 to the 1958 Agreement on approvals and markings of these products.

GRRF-86-40 | UN R90: Proposal for amendments Proposal to resolve inconsistencies present from Supplement 2 to the 02 series of amendments resulting from the approval of proposals in documents GRRF/2014/23/Rev.2, GRRF/2015/22 and GRRF/2016/22. The proposal also introduces provisions for L category (motorcycle and related) vehicles.

GRRF-86-40/Rev.1 | UN R90: Proposal for amendments Proposal of requirements for L category vehicles. The original proposal addressed a broader range of issues and could not be finalized during the GRRF session. This document allows items where consensus was reached to move forward for WP.29 consideration.

GRRF-86-41 | UN R90: Draft proposal for amendments to Annex 7 Proposal to add replacement brake components for L₆ and L₇ (quadricycles) to the regulation, to correct references, and to clarify the text. This proposal aligns UN R90 with UN R78 (motorcycle braking).

GRRF-86-39 | UN R90: Report of the Special Interest Group

WP.29/2016/58 | Proposal for Supplement 3 to the 02 series of amendments to Regulation No. 90 Proposal to introduce provisions for the approval of replacement brake discs for L-category (motorcycle and related) vehicles, to remove tables specifying general values for replacement discs and drums that are identical to the original, change the maximum permitted thickness variation of discs for medium and heavy vehicles from 0.030 mm to 0.040 mm, and clarify the text in order to avoid additional administrative and financial costs to the applicant due to misinterpretation of the intent of the text.

GRRF/68/Add.1 | UN R54: Supplement 23 Addendum 1 to the Report of the GRRF on its 86th session

GRRF-86-25 | UN R75: Proposal for a Corrigendum Proposal to correct a mistake in Supplement 17 to UN R75 (adopted document WP.29/2017/8). Annex 7, Paragraph 1.2., Footnote 1 should refer to UN R54, not UN R106.

GRRF/2018/6 | Proposal for amendments to Regulation No. 106 This document consolidates previous documents GRRF/2017/19 and informal document GRRF-84-17 taking into account the request for addition of tyre sizes and tyre classification codes common in the United States and standardised by the Tire and Rim Association, but needed to be added to UN Regulation No. 106 in order to permit their type approval in order to conform to Regulation EU 167/2013 for tyres to be exported to Europe. It includes addition/modifications of some paragraphs to the main text of the Regulation as well as the addition of some tyre size designations to Annex 5 and Annex 7:<ol class="alpha"><li>ISO 4251-4 replaced by ISO 18805</li><li>Paragraph 2.33.2 deleted since new tables for IF and VF were added to Annex 7</li><li>Paras 3.2., 3.2.2. and 5.4. modified because "tyres submitted for approval" cannot bear an approval mark until approved and the "only" as it is written can be misunderstood. Para. 3.2.2. was aligned to the wording in other UN Regulations. Reference to para. 3.3 in paragraph 5.4. is deleted because paragraph 3.3 does not refer to specific markings</li><li>Para 6.1.2. amended to align the wording to the headers in Annex 5 and to correct the reference to the footnote</li><li>Para 6.2.1. amended to restore the proper references after renumbering resulting from the latest Supplements</li><li>The amendment of Annex 5, Table 5 adds the value for the overall diameter (D) in column (*) that applies to tyres marked with classification code "I-3"</li><li>Annex 5, Table 6, Note 1 amended because most of the tyre sizes listed in the table, especially those identified by the "classification code I‐3" (i.e. Traction tread), are currently available in both versions: ‘implement’ to be used on agricultural machinery and 'IND' to be used on construction vehicles. The two types of tyres have the same type of size designation and the same dimensions. Therefore some manufacturers identify those tyres with the suffix 'IND' rather than with the suffix 'IMP' thus applying the variation of load capacity with speed as published in Annex 7 Part E. The reason for this proposal is to avoid a duplication of tables with a new table only replacing the suffix IMP with the suffix IND.</li><li>The addition of the footnote to Annex 5, Table 7 answers the request by GRRF to introduce appropriate formulae in the Regulation instead of continuously updating Annex 5.</li><li>References in Annex 7 corrected pursuant to the renumbering following the introduction of three new paragraphs in Supplement 15 approved during the 172nd session of WP.29.</li><li>Annex 7, Part A amended to conform with Tire and Rim Association specifications for code designated diagonal tyres with speed symbol A8.</li></ol>

GRRF-86-31 | UN R106: Proposal for amendments to GRRF/2018/6 and GRRF/2018/12 Proposal to add a paragraph to define the purpose of the "SS" marking introduce by the amendments to UN R106 on agricultural and related off-road tyres.

GRRF-86-42 | UN R106: Proposal for a Supplement as adopted by GRRF Proposal as approved by GRRF to add tyre sizes and tyre classification codes common in the United States and standardised by the Tire and Rim Association, but needed under UN Regulation No. 106 in order to permit their type approval in conformity with Regulation EU 167/2013 for imported tyres. The proposal adds kPa marking specifications for use in measurements and tyre testing. The proposal further includes changes to the text and addition of tyre size designations to Annex 5 and Annex 7:<ol class="alpha"><li>Paragraph 2.33.2 deleted since new tables for IF and VF were added to Annex 7</li><li>Paras 3.2., 3.2.2. and 5.4. modified because "tyres submitted for approval" cannot bear an approval mark until approved and the "only" as it is written can be misunderstood.

GRRF/2018/8 | Proposal for amendments to Regulation No. 108 Proposal to introduce provisions for the approval of retreaded tyres marked with the alpine symbol ("3PMSF" or "snowflake symbol").

GRRF/2018/9 | Proposal for amendments to UN Regulation No. 109 In order to have a Regulation on the retreaded tyres with definitions and provisions structured in the same way of those previously introduced in amendments of "new tyres" Regulations, this amendment:<ol class="alpha"><li>Indicates that for the purpose of this Regulation "tyres" means "pneumatic tyres", so all the text has been reviewed</li><li>Introduces a definition of :<ul><li>"retreader” copy based on that “manufacturer" in the tyres regulations</li><li>Brand name", "Trademark", "Trade description" and "Commercial name" as defined in the tyre regulations</li><li>Material manufacturer / material supplier</li></ul></li><li>Takes into account the rounding rules (already approved in the other tyre regulations) for the calculation of width and diameter of the tyres</li><li>Aligns the title and the provisions of the para. 12 related to the names and addresses of Technical Services, Approved Laboratories and administrative Department with their equivalent in the tyres regulations </li></ol>

GRRF-86-24 | UN R109: Proposal for amendments Pursuant to Supplement 21 to UN R54 replacing PSI with kPa to indicate tyre inflation pressures, UN R109 requires updating. This proposal would allow both markings under UN R109 because the life cycle of the carcasses spans several years.

GRRF/2018/9 | Proposal for amendments to UN Regulation No. 109 In order to have a Regulation on the retreaded tyres with definitions and provisions structured in the same way of those previously introduced in amendments of "new tyres" Regulations, this amendment:<ol class="alpha"><li>Indicates that for the purpose of this Regulation "tyres" means "pneumatic tyres", so all the text has been reviewed</li><li>Introduces a definition of :<ul><li>"retreader” copy based on that “manufacturer" in the tyres regulations</li><li>Brand name", "Trademark", "Trade description" and "Commercial name" as defined in the tyre regulations</li><li>Material manufacturer / material supplier</li></ul></li><li>Takes into account the rounding rules (already approved in the other tyre regulations) for the calculation of width and diameter of the tyres</li><li>Aligns the title and the provisions of the para. 12 related to the names and addresses of Technical Services, Approved Laboratories and administrative Department with their equivalent in the tyres regulations </li></ol>

GRRF-86-38 | IWVTA: Status report to GRRF

IWVTA-25-06 | Regulatory strategy when voluntary systems become mandated OICA perspectives for addressing cases of technologies voluntarily installed on vehicles by manufacturers that subsequently become subject to mandatory installation. In particular, the presentation addresses cases where a UN Regulation addresses technologies that are optional in some markets, but mandatory in others. For example, UN R116 includes both vehicle alarms and vehicle immobilizers. Alarms are presently optional across parties to the 1958 Agreement, but some parties require immobilizers. This divergence creates confusion over the validity of UN R116 approvals across all parties to the Agreement.
