Upon the special invitation of the Chair, the following NGOs participated: La Fédération de la Manutention (FEM) and Imported Tyre Manufacturers Association (ITMA).

2. GRRF considered the agenda prepared for the eighty-first session and adopted it (ECE/TRANS/WP.29/GRRF/2016/1 and Add.1) as updated and reproduced in GRRF‑81‑16, including all informal documents received until the session’s starting date.

3. GRRF also adopted the running order for the session as proposed in GRRF-81-01. The informal documents distributed during the session are listed in Annex I of the session report.

4. The secretariat introduced GRRF-81-15, announcing that the next GRRF session would take place on 20-23 September 2016 and recalling that the deadline for the submission of official documents would be 24 June 2016.

5. The secretariat reminded that Footnote 5 in the table of Annex 3 in the 01 series of amendments to Regulation No. 131 imposes the review of the target speed in cell H2 before 1 November 2021.

6. As no documents were presented for technical change but only to discuss the splitting of the regulation, GRRF discussed this item in conjunction with item 10© (see para. 54).

7. The Chair of the Informal Working Group (IWG) on MVC reported on the activities of the group’s recent meeting held in Brussels on 26 October 2015. He confirmed that the group was reviewing the several aspects of MCV specified in the Terms of Reference (ToR). He invited the Contracting Parties and other interested stakeholders to join the following meeting, scheduled on 2-3 March 2016 in Brussels. GRRF endorsed the status report.

8. The Chair of GRRF recalled the purpose of ECE/TRANS/WP.29/GRRF/2013/13, adopted during the seventy-fifth GRRF session. The document remained on the agenda of GRRF, pending submission to the World Forum for Harmonization of Vehicle Regulations (WP.29) and the Administrative Committee of the 1958 Agreement (AC.1) of the adopted text for Regulations Nos. 13-H (Brakes of M1 and N1 vehicles), 79 (Steering equipment) and 89 (Speed limitation devices).

9. The expert from Germany gave an oral report on the activities of the Special Interest Group (SIG) of experts dealing with the provisions of Annex 14 of Regulation No. 13. He announced that the group took into consideration the comments received at the previous session of GRRF related to the energy measurement from the battery and to the warning light concept and that the group would submit a revised proposal for the September 2016 session of GRRF.

10. The expert from Germany informed GRRF that he withdrew the proposal made at the at the eightieth session of GRRF for a new Annex 23 to Regulation No. 13 in ECE/TRANS/WP.29/GRRF/2015/20 with provisions for trailers of category O2 without pneumatic connection and equipped with service braking systems with pneumatic energy storage devices.

11. The expert from Hungary presented ECE/TRANS/WP.29/GRRF/2016/19, tabled by the experts from Hungary and the Netherlands, based on GRRF-80-11. GRRF adopted the document with the following correction:
For “Paragraph 2.2.18., amend …”, read “Annex 12, paragraph 2.2.18., amend …”

12. GRRF requested the secretariat to submit the adopted proposal above to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 14 to the 11 series of amendments to Regulation No. 13.

13. GRRF did not receive any new proposal to amend Regulation No. 121 or relevant new information from the Working Party on General Safety (GRSG).

14. The expert from CLEPA recalled the presentation (GRRF-80-06) made by the expert from China at the previous session of GRRF. He presented GRRF-81-31 answering to the proposal contained in GRRF-80-06. The experts from the Czech Republic and OICA confirmed the information provided by CLEPA. GRRF agreed that the consideration of GRRF-80-06 and GRRF-81-31 was completed.

15. The expert from CLEPA introduced GRRF-81-20, proposing an amendment to Footnote 12 in Regulation No. 13. The proposal received some comments and was amended as reflected in GRRF-81-20-Rev.1. GRRF agreed with the proposal and requested the secretariat to distribute the revised document with an official symbol at the next session of GRRF.

16. The expert from CLEPA, Secretary of the IWG on Regulation No. 55 presented GRRF-81-08 with a proposal for a work plan for the finalisation of the work as the mandate of the group was about to terminate. GRRF endorsed the work plan proposed in GRRF-81-08.

17. The expert from CLEPA also presented GRRF-81-06, proposing amendments to Regulation No. 55 in the case of Multiple Vehicle Combinations. GRRF as well as the IWG on MVC supported in principle the proposal and requested that the IWG on Regulation No. 55 prepares an official document for consideration at the next GRRF session.

18. The expert from CLEPA introduced GRRF-81-07, proposing the procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment. The expert from the UK noted that an editorial correction would be needed in paragraph 4.1.1. and proposed to assist the Secretary of the IWG to prepare an official document for consideration at the next GRRF session.

19. The expert from Germany introduced GRRF-81-09 proposing ToR for a new IWG on Agricultural Coupling that would remove the Agricultural Coupling provisions from Regulation No. 55 and would include them in a new Regulation. The proposal received some comments to limit the number of classes, as reproduced in GRRF-81-09-Rev.1. GRRF agreed with the proposal for a new IWG that would take into consideration the work done by the Task Force on Agricultural Couplings (GRRF-81-10). GRRF agreed in principle with the proposal of the expert from Spain proposing generic provisions to be defined, which could be used for the approval of specific agricultural coupling at the national level. The secretariat noted that GRRF-81-10 was based on a former version of Regulation No. 55 and proposed that the new IWG on Agricultural Coupling would take into consideration the latest version of Regulation No. 55. GRRF agreed that the expert from Germany would chair the IWG and that the expert from the Comité Européen des groupements de constructeurs du machinisme agricole (CEMA) would provide the secretariat of the group. GRRF requested that the IWG would first revise and clarify the ToR of the group.

20. The expert from EC recalled the purpose of GRRF-80-29 aimed at addressing the situation in which coupling balls would be installed right in front of registration plates or rear fog lamps. The proposal received some comments, related to the restriction on the use of a release key in paragraph 1.1.4., and he drafted a revised proposal as reproduced in GRRF-81-34. GRRF adopted the proposal as reproduced in Annex II of this report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 6 to the 01 series of amendments to Regulation No. 55.

21. GRRF agreed with the proposal of the expert from EC to reintroduce ECE/TRANS/WP.29/GRRF/2015/41 under agenda item 5(a) and to reconsider the proposal clarifying the possibility to install means to disable the ABS function in certain conditions for L-category vehicles. The expert recalled that a majority of experts expressed specific concerns related to the condition (f) in the proposal at the previous session and therefore agreed to delete it, as shown in GRRF-81-28. The proposal, received some comments to amend the text in a more stringent manner. The expert from IMMA advocated for transitional provisions aligned with those of Euro 5 in Europe. He added that the newly proposed wording was too restrictive and may exclude some vehicles that were already equipped with the feature. GRRF agreed therefore on longer transitional provisions for existing vehicle types, and also to not excessively restrict the kind of vehicle that could be equipped with the ABS off switch function, by softening the wording of these provisions. The Contracting Parties agreed on the amended proposal GRRF-81-28-Rev.1. The expert from Italy expressed a scrutiny reservation on the provisions related to the off road switch. GRRF adopted the proposal as reproduced in Annex III and requested the Secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as a new 04 series of amendments to Regulation No. 78, subject to final review by GRRF in September 2016.

22. The expert from EC recalled the purpose of ECE/TRANS/WP.29/GRRF/2015/42, proposing to apply to tricycles the existing Anti-lock Braking Systems (ABS) requirements for Powered Two Wheelers (PTWs). The experts from IMMA and OICA agreed with the proposal. GRRF adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as part of the Supplement 3 to the 03 series of amendments to Regulation No. 78.

23. The expert from IMMA introduced ECE/TRANS/WP.29/GRRF/2016/23 proposing amendments to Regulation No. 78 in order to allow the installation of Emergency Stop Signal on motorcycles. GRRF noted that IMMA was coordinating the related activity at the Working Party on Lighting and Light-Signalling (GRE) to introduce the relevant provisions in Regulation No. 53. GRRF adopted the proposal with the minor correction below and requested the Secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as part of the Supplement 3 to the 03 series of amendments to Regulation No. 78.

In paragraph 5.1.15.1., for “m/s2”, read “m/s2

24. The secretariat recalled the discussion at the November 2015 session of the Executive Committee of the 1998 Agreement (AC.3). He recalled that the 1998 Agreement specifies, in order to amend a Global Technical Regulation (GTR), that a request for authorization to develop an amendment would be adopted by AC.3 GRRF agreed to first make further progress on the work under agenda item 5(a) and then proceed with the development of amendments to GTR No. 3 and the corresponding request for authorization to develop an amendment to GTR No. 3.

25. The expert from CLEPA presented ECE/TRANS/WP.29/2016/22 based on GRRF-80-12 proposing amendments to provisions defined for equivalent brake discs and drums and a relaxation of the requirement on the thickness variation for interchangeable replacement discs or drums. The expert presented a revised proposal GRRF-81-04 limiting the thickness variation requirement modification to vehicles of category O2, O3, N3 and M3. The expert from Italy expressed his concern with the proposed requirement relaxation. After discussion, GRRF agreed on the revised document GRRF-81-04-Rev.1. GRRF adopted the proposal amended by Annex IV to the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 3 to the 02 series of amendments to Regulation No. 90.

26. The expert from CLEPA introduced GRRF-81-05-Rev.1 presenting the characteristics of Carbon – Ceramic brakes and proposing to introduce relevant provisions in the Regulation. After discussion, GRRF invited the expert from CLEPA to prepare an informal document proposing amendments to Regulation No. 90 that would include Carbon – Ceramics brakes for consideration at the next GRRF session.

27. The expert from FEMFM introduced GRRF-81-03 proposing a standard Conformity of Production (COP) form to be annexed to Regulation No. 90 that would specify the audit points checked by the Type Approval Authorities in the COP process. The expert from the Russian Federation explained that the proposal would be in contradiction to the provisions of the 1958 Agreement with regard to COP and that the proposal should be revised to be aligned to the provisions of the Agreement. GRRF didn’t oppose to the idea of streamlining the COP process but preferred that a transversal approach across the UN Regulations would be chosen. Therefore, GRRF invited the expert from FEMFM to present his proposal to the World Forum WP.29 or to the IWG on International Whole Vehicle Type Approval (IWVTA).

28. The secretariat introduced GRRF-81-27 containing the request for clarifications of paragraph 5.2.2.1.1 in Regulation No. 90. Only one minimum shear strength requirement is specified for brake shoe assemblies and one requirement for brake pad assemblies in Regulation No. 90 and it is therefore requested that clarification be provided if these requirements are for both cold and hot shear because ISO 6312 specifies methods for both cold and hot shear tests. GRRF confirmed that Regulation No. 90 requested that the test, according to the mentioned ISO standard, has to be run at ambient temperature only. Several experts noted that a general review of Regulation No. 90 would be useful in order to minimize interpretation issues. Following discussions, the expert from Spain prepared and presented ToR for a SIG of experts to explore whether the issues related to the interpretation of the Regulation were minor and could be managed by GRRF or whether they are significant and would require the establishment of a specific IWG. GRRF agreed with the proposal and endorsed GRRF-81-33.

29. The expert from Italy presented GRRF-81-29 introducing ECE/TRANS/WP.29/GRRF/2016/18. The experts from Spain, UK and EC expressed reservations with the aim of the proposal, taking into account the history of the Regulation No. 90 development. They suggested that a more strategic and coordinated approach was chosen to develop the Regulation. GRRF agreed that this proposal may be reviewed by a SIG dealing with Regulation No. 90.

30. The Chair of GRRF recalled the authorization to develop an amendment to GTR No. 16 (see ECE/TRANS/WP29/AC.3/42) and the sponsorship of the Russian Federation for this activity. The expert from the Russian Federation reported on the work done by the group of interested experts dealing with this amendment, introducing the draft amendment 1 to GTR No.16 in ECE/TRANS/WP.29/2016/2 as well as the report contained in ECE/TRANS/WP.29/2016/3. He explained that GRRF-81-02 contained additional information to show the amendments to the existing text of the GTR as well as the origin of the amended text. GRRF adopted both official documents above (and removed the square brackets in paras. 14 and 20 of ECE/TRANS/WP.29/GRRF/2016/3). GRRF requested the secretariat to submit them to WP.29 and AC.3 for consideration and vote at their June 2016 sessions.

31. The expert from France introduced ECE/TRANS/WP.29/GRRF/2016/11 together with ECE/TRANS/WP.29/GRRF/2016/13 and ECE/TRANS/WP.29/GRRF/2016/14 respectively under agenda items 7(c) and 7(g) below, proposing revised clarifications of the definitions. GRRF adopted the proposal and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their June 2016 sessions, as draft Supplement 18 to the 02 series of amendments to Regulation No. 30, as part of the draft Supplement 21 to Regulation No. 54 and as draft Supplement 9 to the 02 series of amendments to Regulation No. 117.

40. The expert from France introduced ECE/TRANS/WP.29/GRRF/2016/14 together with the corresponding document relevant for Regulation No. 30 (see para. 31 of the session report). The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2016/12 addressing both Regulations Nos. 54 and 117 during the review of amendments proposal for Regulation No. 54 (see para. 33).

32. The expert from France introduced ECE/TRANS/WP.29/GRRF/2016/13 together with the corresponding document relevant for Regulation No. 30 (see para. 31 above).

33. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2016/12, a revised proposal to amend the tyre marking requirements and also containing the amendments previously proposed by the expert from Slovakia. GRRF adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as part of the draft Supplement 21 to Regulation No. 54 and as part of the draft Regulation No. 117.

34. The expert from ETRTO presented ECE/TRANS/WP.29/GRRF/2016/16, proposing amendments to Annex 5 to include new sizes.

35. The expert from France introduced ECE/TRANS/WP.29/GRRF/2016/17 (based on GRRF-80-17) proposing provisions for tyres designed for a “special” application that also fulfil the definition of a “snow” tyre. GRRF requested the secretariat to submit the corrected proposal to WP.29 and AC.1 for consideration at their June 2016 sessions, as part of the draft Supplement 21 to Regulation No. 54.

36. The expert from ETRTO introduced GRRF-81-11 proposing amendments to the requirements for the arrangement of tyre markings of Regulation No. 54. The proposal received some suggestions to simplify the verification of the compliance with the arrangement requirements. GRRF invited the expert of ETRTO to submit a revised proposal for consideration at the next session of GRRF.

37. GRRF did not receive any proposal to amend Regulation No. 75.

38. The expert from ETRTO presented ECE/TRANS/WP.29/GRRF/2016/15 proposing the inclusion in the Regulation of load indexes from 201 to 279 to follow the technical evolution of tyres. GRRF adopted this proposal and requested the secretariat to submit both adopted proposals above to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 14 to Regulation No. 106.

39. The expert from ETRTO presented GRRF-81-12 proposing editorial corrections in Annex 7 and Annex 10 of the Regulation, to align the requirements with those of other tyre Regulations and on the provisions for tests performed on two metre test drums. GRRF requested the secretariat to distribute this document with an official symbol at the next GRRF session.

41. GRRF did not receive any other document to be discussed under this agenda item.

42. The secretariat referred to the status report (WP.29-167-04) of the secretariat on the UNECE activities on vehicle automation. The expert from IMMA stated that L-category vehicles should be taken into account at an early stage for road safety reasons. The expert from Germany noted the work done by the IWG on Automated Commanded Steering Function (ACSF) on L-category vehicles and invited the expert from IMMA to contribute to the activities of the IWG.

43. The expert from Japan informed GRRF about the G7 transport ministers’ activities. The first meeting dedicated to vehicle automation took place during the motor show in Frankfurt in September 2015. The declaration following this meeting stated the importance of the work done and to be done at WP.29 on vehicle automation. He reported about the working group of Sherpa’s that took place in Berlin (Germany) in January 2016, to manage the transition between Germany and Japan for the next G7 Transport Minister meeting in Karuizawa Town on 24-25 September 2016, which would be dedicated to Cyber Security and Privacy in the context of the transport and the automotive sector.

44. The Chair recalled the RCP demonstration organized during the previous session of GRRF. The expert of Germany explained that the draft “ACSF Category A” may cover the requirements for such systems. GRRF agreed with his proposal to handle this matter together with the agenda item 9(c) on ACSF.

45. The expert from Japan gave a status report on the activities of the IWG on ITS/AD. He recalled that, since September 2015, two sessions took place in Geneva in November 2015 and that the group: (1) designated the representative of Finland as the IWG on ITS/AD Ambassador to WP.1 and its informal group, (2) continued consideration on the definition of automation levels, (3) would further address cyber security and privacy issues on the basis of guideline proposals tabled by Japan and Germany, (4) exchanged information on the activities at the WP.29 subsidiary bodies and (5) elected Mr. Inomata and Mr. Yarnold as Co-Chairs of the group.

46. The secretariat informed GRRF of the activities of UNECE during the 22nd ITS World Congress that took place in Bordeaux (France) in October 2015. He reported that a ministerial round table moderated by the director of the sustainable transport division adopted the Manifesto “ITS for mitigating Climate Change”. He added that the UNECE ITS Flagship event co-organised with the French Ministry of Environment took place two days after the ministerial round table and that the round table explored ways to implement the vision expressed in the Manifesto.

47. The expert from EC informed (GRRF-81-30) GRRF about the Collaborative ITS (C-ITS) platform report. The secretariat noted that the so-called “Day 1 list” in the report contained mainly systems directly related to road vehicles or indirectly, by interacting with road vehicles through their connectivity. He wondered whether EC would wish to contribute at the World Forum level on these systems. The expert from EC explained that no strategy was decided at this stage but he expected that the type-approval requirements for theses vehicle-related systems could be handled by the World Forum, if non-EU Contracting Parties would express their interest in these activities and would wish to contribute.

48. The expert from CLEPA recalled, on behalf of CLCCR, the proposal ECE/TRANS/WP.29/GRRF/2016/20 previously adopted by GRRF with a scrutiny reservation. CLCCR reviewed the text in square brackets and proposed to delete it as proposed in GRRF-81-13. GRRF adopted the proposal as amended by Annex V to the report and requested the secretariat to submit it together with ECE/TRANS/WP.29/GRRF/2013/13 to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 5 to the 01 series of amendments to Regulation No. 79.

49. The Chair of GRRF recalled the activities done by the IWG on ACSF and proposed to postpone the discussion on LKAS (ECE/TRANS/WP.29/GRRF/2015/2 and GRRF-79-04) to make sure that the findings of the informal group could be reflected when working the technical provisions for LKAS. The expert from France recalled that the work on LKAS had a high priority and invited GRRF to reflect on whether a discussion on the submitted documentation should take place at this session. The experts from Germany and OICA agreed that the proposal produced by the SIG on LKAS was of a high quality but noted that some definitions should be aligned with those of ACSF. Therefore, GRRF agreed to defer the discussion to the September 2016 session. GRRF noted that LKAS were considered as discontinuous corrective steering, while ACSF would cover systems similar to LKAS but performing continuously. GRRF agreed that the boundaries of these systems needed clarification. GRRF requested the IWG on ACSF to work on the boundary definitions. GRRF agreed to resume consideration of this item at its nest session.

50. The expert from Germany, on behalf of the Co-Chairs of the IWG on ACSF, introduced GRRF-81-32 presenting the status of the work done (GRRF-81-18) by the IWG on ACSF. He explained that the IWG was working on the provisions for the proposed five categories of ACSF as well as requirements and testing procedures for the proper assessment of the safety performance of these functions. He clarified that the speed limit for Category E systems would be 130 km/h but that other Categories could work at higher speeds. GRRF endorsed the status report and agreed to resume consideration of this agenda item at its next session.

51. GRRF noted that the ToR of the IWG on ACSF, being submitted for adoption at the March 2016 session of WP.29, were not clearly stating whether the group shall address RCP as an ACSF Category A as drafted by the IWG. Therefore, GRRF requested the IWG to address RCP and requested the secretariat to note this formal request in the session report.

52. The GRRF Ambassador presented GRRF-81-19 reporting on the activities of the IWG on IWVTA and its subgroups. GRRF noted the progress done by the IWG. GRRF also noted that the pre-testing task force would test procedures related to the draft Regulation No. 0 and that GRRF actions related to IWVTA should ideally be completed by February 2016. The experts noted the work undertaken on the revision of the EU framework Directive and asked to the expert from EC whether it would have an impact on the adoption of the draft Revision 3 to the 1958 Agreement and on IWVTA. He answered that the process for adoption may be impacted.

53. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2016/9 proposing a new Regulation on Tyre Installation. The proposal received some comments to harmonize the provisions with those of the corresponding EU Regulation No. 458/2011 (GRRF-81-26). GRRF adopted the proposal as amended by Annex VI to the report and requested the secretariat to submit the amended proposal to WP.29 and AC.1 for consideration and vote in June 2016.

54. The expert from OICA presented ECE/TRANS/WP.29/GRRF/2016/6 removing (as suggested by the IWG on IWVTA) the provisions on ESC and Brake Assist Systems (BAS) from Regulation No. 13-H, taking into consideration the comments received at previous sessions of GRRF as well as the transitional provisions proposed by the expert from UK in ECE/TRANS/WP.29/GRRF/2016/10. He introduced ECE/TRANS/WP.29/GRRF/2016/7 proposing a new Regulation on BAS. He also introduced a proposal for a new Regulation on ESC (ECE/TRANS/WP.29/GRRF/2016/8). After discussion, GRRF agreed on the revised proposals in GRRF-81-23, GRRF-81-24 and GRRF-81-25.

55. GRRF adopted ECE/TRANS/WP.29/GRRF/2016/6 as amended by Annex VII to the report and requested the Secretariat to submit it as well as the adopted proposal in ECE/TRANS/WP.29/GRRF/2013/13 to WP.29 and AC.1 for consideration and vote in June 2016 as draft 01 series of amendments to Regulation No. 13-H

56. GRRF adopted ECE/TRANS/WP.29/GRRF/2016/7 as amended by Annex VIII to the report and requested the Secretariat to submit it to WP.29 and AC.1 for consideration and vote in June 2016.

57. GRRF adopted ECE/TRANS/WP.29/GRRF/2016/8 as amended by Annex IX to the report and requested the Secretariat to submit it to WP.29 and AC.1 for consideration and vote in June 2016.

58. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2016/4 proposing to remove the TPMS requirements from Regulation No. 64 as suggested by the IWG on IWVTA. He presented ECE/TRANS/WP.29/GRRF/2016/5 proposing a new Regulation on TPMS. Following discussion, GRRF agreed on the proposals as amended and reproduced in GRRF-81-21 and GRRF-81-22.

59. The expert from EC proposed amendments (GRRF-81-17) to ECE/TRANS/WP.29/GRRF/2016/5 clarifying that the manufacturer has the obligation to design a TPMS system which shall detect underinflation under a wide range of driving conditions and not only in the conditions of the test procedures in Annex 3 of the Regulation. GRRF adopted with the proposal as amended (GRRF-81-17-Rev.1). GRRF noted that the agreed proposal would not modify the test procedures as described in Annex 3 of the Regulation. The expert from the Russian Federation and some type-approval authorities raised a question about general provisions in UN Regulations for which no procedure was defined to verify the compliance with these general provisions for manufacturers. GRRF suggested that WP.29 could have a general discussion on the compliance off the test procedures and could provide guidance to the WP.29 subsidiary bodies.

60. GRRF adopted ECE/TRANS/WP.29/GRRF/2016/4 as amended by Annex X of the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as draft 03 series of amendments to Regulation No. 64.

61. GRRF adopted ECE/TRANS/WP.29/GRRF/2016/5 as amended by Annex XI of the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions.

62. GRRF did not receive any new document to be discussed under this agenda item.

63. The expert from OICA presented ECE/TRANS/WP.29/GRRF/2016/21 proposing to extend the possibility of actuating the service braking system to vehicles of categories M2 and N2 below five tons. The proposal received some comments on possible safety risks. The expert from Switzerland explained that his country, due to specific geographic characteristics, had long roads with significant slopes and that the requirements shall take this specificity into consideration. The expert from OICA stated that, due to speed limiter (90 km/h), fully loaded vehicles of category M2 of N2 below five tons would have a smaller kinetic energy than fully loaded vehicles of category N1 driving at 130 km/h, therefore, the proposal is not introducing any road safety issue. The expert from Denmark noted that a tell-tale could be provided, in combination with the system actuating the service brakes, to make the driver aware of the service brake application. GRRF agreed to continue consideration of this agenda item at September 2016 session of GRRF and invited GRRF to provide evidences that no additional safety risk would be expected if the requested extension would be granted.

64. The expert from EC reported (GRRF-81-30) on Gear 2030, being a high level group consisting of the executives of the European automotive sector, relevant Ministers and Commissioners of the European Commission. He added that one of the goals of the group was to develop a roadmap for highly automated driving, within two years.

65. The expert from Japan informed on the activities in Japan concerning the establishment of a guideline for the so called “dead-man system” bringing automatically a vehicle to a stop, when there is no obvious driver engagement, as the country faced lately severe bus accidents related to drivers’ unconsciousness. He explained that the guideline would be aligned with the provisions defined by the IWG on ACSF on the Minimum Risk Manoeuvre.

66. The secretariat introduced GRRF-81-15 reporting on the highlights of the 167th session of WP.29 relevant for GRRF. For more information, please refer to the session report (ECE/TRANS/WP.29/1118).

67. The secretariat introduced GRRF-81-27 under agenda item 6 (see para. 28 above).

68. The Chief of the Vehicle Regulations and Transport Innovations Section, Mr. W. Nissler, informed GRPE about the abolishment of four General Service (G) posts within the United Nations Economic Commission for Europe (UNECE) as decided by the UN General Assembly on 23 December 2015. He explained that a G post was abolished in the Vehicle Regulations and Transport Innovations Section since 1 January 2016 due to the immediate retirement of the current incumbent. He hoped that this unfortunate situation would not affect future services to be provided by the section.

69. Learning that Mr. Jean-Claude Noirhomme (ETRTO) would retire and, therefore, no longer attend the sessions, GRRF acknowledged their considerable contributions to the activities of the group. GRRF wished him a long and happy retirement.

He mentioned that the group of experts considered a list of issues for future consideration. He added that the group already reached a common understanding about the type definition interpretation of replacement parts. He concluded that a final report would be delivered at the September 2017 session of GRRF, with a potential recommendation for the establishment of an informal working group on Regulation No. 90 (and corresponding draft terms of reference), if the experts would conclude that it is necessary. He announced that the next meeting of the SIG would be organized in April 2017 and requested that the secretariat circulate an invitation by email.

26. The experts from OICA and CLEPA expressed concerns with elements of the presentation of the expert from Spain. The Chair of GRRF noted the number of items for consideration and advised the group of experts to define priorities and to separate the work that would cause an extension of scope of the Regulation e.g. replacement calipers.

27. The expert from Spain recalled the discussion that took place at the seventy-fifth session of GRRF (ECE/TRANS/WP.29/GRRF/75, para. 49) and that was related to safety issues on proving grounds or on public roads linked to braking tests.

GRRF noted that Annex 5 was containing non-metric tyre sizes not in line with the general formulae contained in the Regulation; therefore, GRRF wondered whether the right approach would be to introduce the appropriate formulae in the Regulation instead of continuously updating Annex 5. The expert from ETRTO agreed to address this proposal and to submit, if suitable, revised proposals for consideration at the next session.

37. The expert from ETRTO presented GRRF-83-15 with new tyres sizes to be included in Annex 5. GRRF adopted the proposal.

38. The expert from ETRTO presented a revised proposal ECE/TRANS/WP.29/GRRF/2017/9 with provisions which were already supported at the last session. He introduced the revised transitional provisions related to new marking requirements. The experts from EC and UK proposed an alternative wording (GRRF-83-14). Both proposals received several comments. Therefore GRRF agreed to adopt the agreed provisions that would not be subject to transitional provisions and to remove the others, as reproduced in GRRF-83-23.

39. GRRF requested the secretariat to submit the adopted proposals ECE/TRANS/WP.29/GRRF/2017/9 amended by Annex VI (based on GRRF-83-23 and GRRF-83-15) as well as ECE/TRANS/WP.29/GRRF/2016/39 as draft Supplement 15 to Regulation No. 106 (Agricultural tyres) to WP.29 and AC.1 for consideration and vote at their June 2017 sessions.
