2. The first session of GRVA was opened by the GRVA Secretary. The Secretary of WP.29 informed GRVA about the Inland Transport Committee request (ECE/TRANS/274, para. 52) and about the decisions of WP.29 (ECE/TRANS/WP.29/1139, para. 33) on the Working Party on Brakes and Running Gear and GRVA. The secretariat invited the experts of GRVA to elect a Chair for the first session of GRVA. The expert from the United States of America requested the strict application of Rule 37 of the Rules of Procedures and to proceed with the vote at the end of the week. The Secretary asked whether he should chair until the end of the session, until the election takes place, or whether GRVA should choose a Chair. GRVA decided that the first GRVA session shall be chaired by Mr. B. Frost (United Kingdom of Great Britain and Northern Ireland).

1. Adoption of the agenda

3. GRVA considered the provisional agenda prepared for this first session and adopted it (ECE/TRANS/WP.29/GRVA/2018/1). The adopted agenda is reproduced in
GRVA-01-14, including all informal documents received until the session’s starting date. GRVA also agreed on the running order for the session as proposed in GRVA-01-01 with the modification suggested by the expert from the United States of America to move the election of officers for the year 2019 to the end of the session as per Rule 37.

2. Election of Officers

4. In compliance with Rule 37 of the Rules of Procedure (TRANS/WP.29/690 and Amends. 1 and 2), GRVA called for the election of officers on Friday morning. Before the election took place, the expert from Germany provided background information to GRVA, why his delegation would oppose the election of Mr. Frost at the time of the vote for the Chair for the year 2019. He explained that Germany would like to fully contribute to the strategic work of GRVA and would therefore nominate a German expert as candidate Chair for the year 2020. GRVA elected Mr. B. Frost (United Kingdom of Great Britain and Northern Ireland) as Chair of GRVA for the sessions 2019, with the absolute majority of the present delegations voting in his favour. GRVA did not elect a Vice Chair and agreed, subject to WP.29 endorsement, to proceed with this at its next session.

3. Highlights of the March and June 2018 sessions of WP.29

5. The secretariat introduced GRVA-01-13, informing on the highlights of the March and June 2018 session of WP.29. The secretariat announced that the next GRVA session would take place from 28 January to 1 February 2019 and advised that the deadline for the submission of official documents would be 2 November 2018.

4. Exchange of views on vehicle automation related work priorities

6. The Chair recalled that he had initiated an informal consultation over the summer 2018 to collect the list of items that Contracting Parties would wish to be addressed by GRVA. The Chair presented GRVA-01-33 containing the responses received together with those provided in WP.29-175-08 and WP.29-175-29, some 40 items in total. He proposed classifying the items into work streams to facilitate the participation of subject experts, e.g. Data management, Sensors (spatial awareness), Functional requirements, New assessment procedures and “other items”. The GRVA experts confirmed that the document contained all input received.

7. The expert from China offered suggestions on the structure, work programme and meeting arrangements of GRVA (reproduced in GRVA-01-32).

8. The expert from AAPC stated that they would like to support the work done under this agenda item, he suggested assessment criteria to be considered when working on priorities for GRVA.

9. The expert from the United States of America introduced GRVA-01-03 proposing some considerations relevant for the work of GRVA under the 1998 Agreement. The expert from ITU reported on their experience in the Task Force on Cyber Security and Over-the-Air issues (TF CS/OTA) and highlighted the need for assistance from contracting parties when drafting documents to ensure the appropriateness of texts drafted to address specificities of the 1998 Agreement (and the context of self-certification). The expert from Germany, Co-Chair of the Informal Working Group (IWG) on Automated Commanded Steering Function (ACSF), recalled the ambition of his group to draft technical requirements suitable for use under both the 1958 and the 1998 Agreements.

10. The expert from the Russian Federation presented GRVA-01-05 with their proposal for priorities. He recalled that decisions on priorities can only be made by the Executive Committee (AC. 3) for items to be handled under the 1998 Agreement. He also recalled the need for a technical sponsor for activities under the 1998 Agreement.

11. The expert from OICA presented GRVA-01-28 with information on the priorities of the industry that would require regulatory activities from GRVA. He regretted that the IWG on ACSF were not drafting provisions for so called Hands-off Lane Keeping Systems as SAE Level 2 even though this technology was already sold in some markets, e.g. in the United States of America. The Co-Chair of the IWG on ACSF and the expert from the Netherlands clarified that the IWG on ACSF considered hand off systems as Level 3 systems and not as Level 2. The Chair noted the differences between the priorities reported in GRVA-01-28 by OICA and those communicated by most of the manufacturers in their media statements. In response the expert from OICA prepared a revised document (GRVA-01-28-Rev.1) but was unable to demonstrate the technological and market priorities questions raised by GRVA. The expert from OICA also presented considerations on possible coordination of work between the subsidiary bodies (GRs) of WP.29. He suggested the nomination of GR Ambassadors on the model of IWVTA Ambassadors.

12. The expert from UITP stated the need to first address the safety of automated shared fleets for use by public transport systems.

13. The expert from ITU stated the need for GRVA to define a cluster around communication, including Platooning.

14. The expert from CLEPA insisted on the need to finalize the work on Automated Commanded Steering Function (ACSF).

15. The expert from GTB presented GRVA-01-06 with considerations on lighting and light-signalling for automated driving systems, highlighting the wish to work on this at the Working Party on Lighting and Light-Signalling (GRE). The expert from the Russian Federation suggested to explore ways to address this issue in the context of the Horizontal Regulation discussions. He mentioned that the presentation had already been made at WP.29. The expert from GTB also raised the question of coordination between GRs on automation as the expert from OICA had done. The expert from Japan recalled that WP.29 agreed to discuss coordination issues on automation. GRVA agreed that coordination issues would naturally be discussed at WP.29.

16. The expert from China introduced GRVA-01-16,

17. GRVA agreed that the items listed in GRVA-01-33 and the classification proposed should be reviewed at the next session under agenda item 4.

18. GRVA reviewed WP.29 informal documents WP.29-175-08 and WP.29-175-29 referred by WP.29 to GRVA as well as the list of items noted in the provisional agenda. GRVA had an extensive discussion on each item. The expert from OICA stated that the ongoing work was adequate to address industry priorities. The experts received clarifications on the meaning of each item by the proposal authors. They exchanged views on the priority that could be assigned to each item as well as the potential necessity to start regulatory activities (or not). GRVA concluded that GRVA is able (from the point of view of knowledge and expertise) to address each item in the list (GRVA-01-39) reproduced in Annex II to this report and was ready to fulfil its mandate as defined by WP.29 and/or AC.3. GRVA agreed to consider other items and possibly extend this list in the coming sessions.

6. Autonomous/automated and connected vehicles
6. (a) Task Force on Automated Vehicle Testing and subgroups

21. The expert from UK presented the developments in 2018 on the creation of the Task Force on Automated Vehicle Testing (“AutoVeh”) and its two subgroups called “SG-1” and “SG-2”, established under WP.29. He presented that the aim of these groups was to develop a novel innovative concept for the assessment of Automated Driving technologies. He recalled that Terms of Reference (ToR) for this group were not adopted and that “AutoVeh” was transferred to GRVA in June 2018 (including the corresponding draft ToR). The expert from Japan reported on the status of the discussions in the groups and presented slide 3 in GRVA-01-35. GRVA agreed that the parent group (“AutoVeh”) would no longer be needed as the management of SG-1 and SG-2 would take place at GRVA.

22. The expert from Japan Co-Chair of “AutoVeh” presented ToR of both Subgroups (GRVA-01-07 and GRVA-01-11). The expert from EC sought clarity on the scope of SG-1 and on possible overlap with IWG on ACSF. The expert from China mentioned the lack of clarity of the proposed structure and proposed to classify existing and new work items to create groups with sufficient compatibility for existing and new ones in the future. He also mentioned the challenges related to the work on simulation and on-road testing due to the differences in traffic conditions and traffic rules within the contracting parties. He recommended to not endorse the ToRs proposed at this session. The expert from Germany asked about potential work duplications and asked whether GRVA or WP.29 already agreed on the three pillars concept mentioned in the ToR. The expert from Japan answered the questions.

23. After discussion, GRVA did not endorse GRVA-01-07 and GRVA-01-11 but, noting arrangements were already in place for further meetings, agreed that the groups continue to work until the next GRVA session. GRVA suggested that the group should refine the ToR to develop the novel innovative concept to verify the compliance with technical requirements (such as those developed within the IWG on ACSF) and demonstrate the validity of the new approach. The group should also prepare a full discussion on the three pillars approach and start working.

24. The secretariat recalled the decision of WP.29 to defer the document on artificial intelligence and vehicle regulations (WP.29-175-21) to SG-1.

GRVA-01-07 | Automated Driving: Proposed terms of reference for Subgroup 1 Proposed objectives and guidelines for an informal working group on the physical certification of automated vehicles (i.e., proving ground tests) and audit of manufacturers (certification of the management of safety-critical aspects such as cybersecurity, data protection, and software updates).

6. (b) Cyber security and data protection

25. The expert from Japan, Co-Chair of the Task Force on Cyber Security and Over-the-Air issues (TF CS/OTA) presented GRVA-01-19 introducing GRVA-01-17 and GRVA-01-18 with recommendations on software updates and on cyber security. He invited the experts to send comments on the recommendations until 28 October 2018. The expert from France congratulated the Task Force for the work done. The expert from the United States of America confirmed that they had participated in the last meeting of the group and explained that both recommendations would require amendments to make them compatible with the 1998 Agreement (especially in the self-certification context) and offered to provide comments.

26. The expert from Japan also mentioned that the recommendations contained proposals for a draft UN Regulation for cyber security and a draft generic Annex that could be added to relevant UN Regulations with regards to software number management. He added that the innovative approaches proposed would probably require some verification before adoption and that these activities would require an extension of the group’s mandate or the creation of a new group.

27. GRVA invited the Task Force to use the remaining time on their current mandate to develop a verification programme that could be considered at the second session of GRVA. GRVA also requested the Chair to report on these activities at WP.29.

6. (d) Automatically Commanded Steering Function

29. The expert from OICA presented ECE/TRANS/WP.29/GRVA/2018/2, as amended by GRVA-01-22 introducing provisions for ACSF systems of Category C with a so called 2-steps human machine interface for the lane change activation. The expert from France supported the proposal. The expert from the European Commission welcomed this proposal. The proposal received some comments from the experts from Germany, Korea, Netherlands, and Sweden namely on the deletion of some provisions, the proposed amendment to extend the time by which a lane change manoeuvre shall begin and the proposed Annex 9. GRVA invited interested experts to prepare a revised proposal addressing the comments received.

GRVA-01-22 | UN R79: Proposal to amend GRVA/2018/2 (Supplement to the 03 series of amendments) Changes to the proposal for amendments to the requirements for Automatically Commanded Steering Functions (ACSF) of Category C, introducing specific provisions for the use of a lane change function with a two-step Human Machine Interface (HMI).
GRVA/2018/2 | UN R79: Proposal for a Supplement Proposal for amendments to the requirements for Automatically Commanded Steering Functions (ACSF) of Category C, introducing specific provisions for the use of a lane change function with a two-step Human Machine Interface (HMI).

30. The expert from Germany presented the status report of the IWG on ACSF (GRVA-01-37). She requested guidance on whether the group should develop provisions for a new regulation, as the activities would go beyond the scope of UN Regulation No. 79 as originally envisaged. GRVA agreed with the suggestion of the IWG that technical provisions for new regulation should be developed. She introduced GRVA-01-08 with amended ToR for the group in line with the decision of GRVA in favour of a new regulation. GRVA endorsed the proposal for revised ToR as reproduced in Annex III to the report and noted that the timeline was ambitious. The Chair agreed to bring this point to the attention of WP.29.

GRVA-01-08 | UN R79: Proposal for revised ToR and RoP of the IWG on ACSF Updated goals and objectives of the Automatically Commanded Steering Functions expert group based upon the work to date, including the possibility to establish requirements for automated lane-keeping functions as a new UN Regulation. The previous terms of reference focused only on amendments to UN R79.
GRVA-01-37 | Status report of the ACSF informal group

31. The secretariat presented GRVA-01-36 with a correction proposal to align the three linguistic versions of UN Regulation No. 79. GRVA agreed with the proposal and requested the secretariat to make the necessary corrections in the English version as follow:

Paragraph 2.4.15., correct to read:

“2.4.15. An ACSF is in “active mode” (or “active”) when the function is switched on and the conditions for being active are met. In this mode, the system continuously or discontinuously controls the steering system is generating, or is ready to generate, a steering control action to assist the driver."

GRVA-01-36 | UN R79: Proposal for a Corrigendum Proposal for an editorial correction to paragraph 2.4.15.

32. The expert from CITA introduced GRVA-01-25 with a proposal to include in UN Regulation No. 79 Periodic Technical Inspection (PTI) related provisions with regards to ACSF of Category B2. GRVA wondered why the proposal was based on an outdated working paper (ACSF-06-28) of the IWG on ACSF. GRVA agreed that the document should be addressed to the Task Force on PTI/ roadworthiness of the ACSF systems led by the expert from Sweden.

GRVA-01-25 | Proposal for PTI on ACSF B2 / Automated Lane Keeping System

33. The expert from Sweden presented GRVA-01-24 with a status report of the Task Force on PTI/roadworthiness of ACSF systems. The expert from the Russian Federation, Chair of the IWG on PTI, invited the Task Force to liaise with the IWG on these issues. GRVA agreed that the group should liaise with the IWG on PTI on Periodic Technical Inspection process related issues and that the Task Force should focus on roadworthiness related provisions linked to the construction of automated vehicles such as continuous self-diagnostic functions, system failure recognition, fault code recording and fault code access.

GRVA-01-24 | Progress report of the group on PTI/roadworthiness provisions for ACSF At its 86th meeting, GRRF recommended to cluster subjects together and form a number of task forces to deal with different issues related to the ACSF work. One task force was devoted to Periodic Technical Inspection (PTI).

34. The expert from AVERE introduced GRVA-01-04 proposing to clarify the existing introduction of UN Regulation No. 79 with regard to the prohibition of approval according to UN Regulation No. 79 of steering systems that incorporate functions by which the steering can be controlled by external signals. The expert from the Republic of Korea stated the importance of addressing this issue. The experts from Germany, the Netherlands, Russian Federation and Sweden stated that the purpose of the proposal was unclear and asked for more information on the context of the proposal. GRVA invited the expert from AVERE to consider whether changes to the text would be preferable to the use of footnotes and suggested he consult the experts and to produce a revised proposal for consideration at the next session.

GRVA-01-04 | UN R79: Proposal for Supplements to the 02 and 03 series of amendments Proposal to permit the limited use (in non-total control use-cases) of external signals to improve the overall reliability and safety of ACSF functions.
6. (e) Complex Electronic (CEL) control system requirements

35. The expert from UK informed GRVA that the work on this item was ongoing, that the current draft was reproduced in GRVA-01-20 and that the outcome of this work could be incorporated in the future proposal emanating from the IWG on ACSF.

GRVA-01-20 | UN R79: Proposal for a revision of Annex 6 (CEL) This document presents the output of an informal group of experts reviewing the content of Annex 6 on complex electronic systems. Its purpose is to update Annex 6 to ensure its suitability when used in the assessment of steering systems featuring advances in automation.
7. Advanced Emergency Braking Systems

36. The expert from EC, Co-Chair of the IWG on Advanced Emergency Braking Systems (AEBS) presented GRVA-01-10 with a status report on the activities of the group on the drafting of a new UN Regulation with provisions applicable to M1 and N1 vehicles as reproduced in GRVA-01-02. He presented the key performance requirements defined for so called vehicle-to-vehicle and vehicle-to-pedestrians Advanced Emergency Braking (AEB) systems and highlighted the open issues discussed by the group on provision for manual AEB deactivation and the definition of performance requirements for vehicle-to-bicycle systems.

37. The expert from UK, supported by the expert from the Netherlands, questioned the proposed value of the maximum differential test speed (42 km/h) that targets collision avoidance. He suggested 50 km/h instead of 42 km/h. He expressed doubts that a staged approach for vehicle-to-pedestrian and vehicle-to-bicycle AEB systems would be appropriate. The expert from OICA justified the value of the maximum differential speed for collision avoidance noting that Euro NCAP was requesting less than this value and justified the staged requirements especially for vehicle-to-bicycle AEBS systems because of the ongoing development process of such systems.

38. The expert from Canada suggested to specify performance-based requirements for all aspects to be tested, including the adhesion criteria of the track surface used for testing. GRVA noted the existing relevant precedent in UN GTR No. 3 and UN Regulation No. 78 and the corresponding value proposed in the draft.

39. The expert from Italy mentioned the risk related to false positive AEB system activation and the need of a manual AEBS deactivation function. The experts from Germany and UK expressed support for provisions on automatic deactivation function in limited cases. They disagreed with the proposal for provisions allowing the manual deactivation of AEB systems.

40. The Chair highlighted the provisions related to the AEBS performance outside of the testing conditions.

GRVA-01-02 | AEBS: Draft Proposal for a new UN Regulation Interim draft text for a light vehicle AEBS regulation prepared on behalf of the informal group on AEBS. It provides the state of play of the discussions held the informal group up to date. It aims at providing the experts of Working Party on Automated/Autonomous and Connected Vehicles (GRVA) the opportunity to react, comment and contribute to work performed by the informal group until now.
GRVA-01-10 | Proposals from the IWG on AEBS Status report of the AEBS informal working group including presentation on the draft light vehicle AEBS regulation (document GRVA-01-02).

41. The Co-Chair of the IWG presented GRVA-01-09 proposing changes to the ToR of the group as well as a mandate extension by one year. GRVA agreed to extend the mandate of the IWG on AEBS for one year until September 2019. GRVA agreed with the goal of the AEBS Chair to present an official document covering vehicle-to-vehicle and vehicle-to-pedestrian collision for adoption at the next GRVA session in January 2019. GRVA also asked the informal working group to present, at the same session, the requirements on vehicle-to-bicycle on the basis of available data.

GRVA-01-09 | AEBS for M1/N1 vehicles: Proposal for revised terms of reference Updated proposal for the goals and objectives of the AEBS informal working group, in particular to establish a new UN Regulation in lieu of the initial expectation for amendments to UN R131 on heavy vehicle AEBS.

42. The expert from Germany referred to UN Regulation No. 131 and presented GRVA-01-30 (and GRVA-01-31 with a calculation tool), introducing ECE/TRANS/WP.29/GRVA/2018/4 which addressed the issues presented during the last two sessions of GRRF concerning the performance of AEBS for heavy vehicles. He explained that this revised proposal was more far reaching than the previous one, not only addressing the manual deactivation switch provisions but also other provisions that would contribute to make AEBS requirements for heavy vehicles corresponding to state of the art vehicle technologies, by changing “the structure” of the Regulation, “the vehicle target” requirements, the “overriding requirements” and the “warning strategy”. He concluded his presentation stating that these changes would help to minimize the false positive activation risks mentioned by the experts from Nordic countries as initial reaction on the German proposals at the last sessions of GRRF.

43. The experts from OICA presented (GRVA-01-21) comments on ECE/TRANS/
WP.29/GRVA/2018/4. The experts from Sweden and Japan expressed reservations on the proposal as they were not in the position at this stage to assess the implications of such far reaching changes on the performance of AEBS systems for heavy vehicles. The experts from Australia, Japan, Netherlands, Norway and Sweden agreed to work with the expert from Germany to review the proposal until the next session of GRVA. The experts agreed to work on this item via virtual meetings and physical meetings around the meetings of the IWG on AEBS.

50. GRVA agreed with the suggestion of expert from Italy to postpone the consideration of this item until the January 2019 session.

GRVA/2018/9 | GTR 3: Proposal for an amendment 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.
9. (b) UN Regulation No. 78

51. The expert from IMMA introduced GRVA-01-42 as a follow-up proposal of
GRRF-86-35 aiming to specify the stop lamp activation criteria for conditions other than only on application of the service brake (e.g. regenerative braking). She explained that the proposal is based on the provisions laid down in UN Regulation No.13-H. The expert of OICA mentioned that they were working on amendments to these criteria. GRVA encouraged the experts from IMMA and OICA to come up with harmonized provisions for UN Regulations Nos. 78 and 13-H and requested the secretariat to distribute the proposal with an official symbol at the next session of GRVA unless an alternative proposal would be submitted by the experts from CLEPA and OICA.

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.
GRVA-01-42 | UN R78: Proposal for amendments Proposal to introduce activation of stop lamps under more conditions than application of the service brake only (e.g. also by regenerative braking).
10. UN Regulation No. 79

52. The expert from UK mentioned the work done on provisions for Remote Controlled Manoeuvring (RCM) as in ECE/TRANS/WP.29/GRVA/2018/3 amended by GRVA-01-26. He informed GRVA that he informally consulted GRVA experts and that further work could be needed. GRVA agreed with his proposal to resume consideration of this proposal or consider a revised consolidated proposal at the January 2019 session of GRVA.

GRVA-01-26 | UN R79: Proposal for amendments to ECE/TRANS/WP.29/GRVA/2018/3 Proposal to clarify that M<sub>1</sub> and N<sub>1</sub> not approved as category G may be equipped with Remote Controlled Maneuvering systems provided they meet the requirements to be classified as such.
GRVA/2018/3 | UN R79: Proposal for a supplement Proposal to introduce provisions in UN Regulation No. 79 (Steering equipment) for the approval of Remote Control Manoeuvring (RCM) systems.

53. The expert from France introduced GRVA-01-38 (based on GRRF-86-13) addressing the accuracy of interpretation of data produced during system assessment. The expert from Germany welcomed the document and proposed to consider the filtering provisions together with the tolerances. Other experts welcomed the document and agreed to study it until the next session. GRVA agreed to resume consideration of this item at its January 2019 session.

GRRF-86-13 | UN R79: Proposal for amendments Proposal from Germany and the Republic of Korea to resolve measurement concerns in the test requirements for ACSF of Category B1 and C. The proposal addresses issues identified in Annex 8, improves reproducibility and robustness of the procedures, fills in gaps in the test cases, and provides additional details on measuring equipment and test execution.
GRVA-01-38 | UN R79: Proposal for amendments based on GRRF-86-13 GRVA-1 agreed to reconsider based upon a formal document at GRVA-2 taking into account particularly concerns over the impact of the filtering change on tolerances and interpretation of results.
11. UN Regulation No. 89

54. In the absence of documents, no discussion took place under this agenda item.

12. UN Regulation No. 90

55. The expert from Spain presented ECE/TRANS/WP.29/GRVA/2018/12 proposing to extend the scope of UN Regulation No. 90 with replacement brake lining assemblies for vehicles of Category L6 and L7, which were recently included in the latest version of UN Regulation No. 78 and to align the provisions in Annex 7 to UN Regulation No. 90 with those in the current text of UN Regulation No. 78. GRVA agreed to resume consideration of this document at its next session.

GRVA/2018/12 | UN R90: Proposal for a Supplement to the 02 series of amendments Proposal to align the text in Annex 7 with UN R78 and to insert the reference to the L<sub>6</sub> and L<sub>7</sub> vehicle categories to respond to requests from the industry for type approval for the replacement brake lining assembly for these vehicles.

56. Due to the lack of time, GRVA agreed to postpone the consideration of
GRVA-01-12 and the oral report of the expert from Spain on the activities of the Special Interest Group of experts on UN Regulation No. 90 until the January 2019 session.

GRVA-01-12 | UN R90: Proposal for a Supplement to the 02 series of amendments Proposal to correct editorial errors and to insert the word "tolerance" in para. The editorial errors originated with documents WP29/2016/58 (relating to GRRF-80-37), GRRF/2015/22 and GRRF-81-04-Rev.1.
13. Revision 3 of the 1958 Agreement

14. Remaining activities from the former Working Party on Brake and Running Gear (handover period)
14. (a) Tyres

59. The Chair of GRVA recalled the information provided by the Secretary of WP.29 that the Working Party on Noise (GRB) had successfully reviewed all formal documents tabled under this agenda item as agreed due to the reorganization of the subsidiary bodies of WP.29. He recalled his commitment to minimize the impact of the structural changes related to GRB and GRVA in terms of technical discussions and proper participation of delegates and experts. Therefore, he offered the experts the opportunity to consider in detail any document under this agenda item, in case a delegation had not attended GRB or would like GRVA to express a view. The experts confirmed that this was not necessary. The Chair of GRVA also offered the opportunity for the expert from the Russian Federation to provide (see GRB-68-16 for more details) an update on the development of the draft Amendment 2 to UN GTR No. 16 (Tyres) should GRVA wish. He recalled that AC.3 had still not formally decided that UN GTR No. 16 would be handled by GRB. GRVA noted the ongoing work done by the Informal Working Group chaired by the expert from the Russian Federation.

14. (b) Mechanical couplings

60. The secretariat presented ECE/TRANS/WP.29/GRVA/2018/10, in the absence of the expert from CLEPA, proposing to clarify some unintentional deletions introduced in UN Regulation No. 55. GRVA agreed with the proposal and requested the secretariat to clarify the follow-up action on this document with the Working Party on General Safety provisions (GRSG).

GRVA/2018/10 | UN R55: Proposal for Supplement 8 to the 01 Series of 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.

61. The expert from Poland introduced ECE/TRANS/WP.29/GRVA/2018/11. GRVA agreed that this proposal should be reviewed by the Working Party on General Safety Provisions.

GRVA/2018/11 | UN R55: Proposal for a 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 applicable” 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).

62. GRVA noted that GRVA-01-29 tabled by the expert from OICA was a new proposal. The expert from OICA agreed to present this document at the next GRSG session.
