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.

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.

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.

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.

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.

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.

17. The Secretary of the IWG introduced ECE/TRANS/WP.29/GRRF/2016/29 (amended by GRRF-82-27) with technical requirements for coupling devices for the purpose of modular vehicle combinations as well as “in-use” requirements for the combination of vehicles. The proposal, supported by GRRF, received some comments about the possibility to verify, at the time of type approval, the compliance with these “in use” requirements. GRRF questioned whether a driver could be requested to verify during a coupling phase the compatibility requirements defined in the proposal. The expert from CLEPA showed that calculation tools were available on the website of his company (www.vbg.se) and argued that it would be possible. GRRF agreed that this aspect of the proposal would need further consideration by the IWG who should recognise that new measures must be enforceable via type approval.

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.

This item was agreed at our Poznan meeting. To our October meeting it was included in the proposal for Item 21. In order to make each proposal easier to comprehend it was now separated out. It was subject to the same principle discussion as Item 20. It was agreed to submit this proposal as an informal document to the GRRF 81.

17. The Secretary of the IWG introduced ECE/TRANS/WP.29/GRRF/2016/29 (amended by GRRF-82-27) with technical requirements for coupling devices for the purpose of modular vehicle combinations as well as “in-use” requirements for the combination of vehicles. The proposal, supported by GRRF, received some comments about the possibility to verify, at the time of type approval, the compliance with these “in use” requirements. GRRF questioned whether a driver could be requested to verify during a coupling phase the compatibility requirements defined in the proposal.

GRRF agreed that this aspect of the proposal would need further consideration by the IWG who should recognise that new measures must be enforceable via type approval.

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.

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.

GRRF requested that the IWG would first revise and clarify the ToR of the group.

17. The Chair of the IWG on the Agricultural Coupling Devices and Components reported on the activities of the group (GRRF-84-27) and presented ECE/TRANS/WP.29/GRRF/2017/13 as amended by GRRF-84-26 with a draft regulation on the Agricultural Coupling. GRRF discussed the texts of para. 4.5. contained in square brackets and requested the group to consider working protection laws. The expert from Sweden proposed to clarify the provisions for remote coupling and remote indication. GRRF agreed that the remote indication should be located where the remote operation takes place. The Chair of the IWG volunteered to submit a revised proposal at the February 2018 session of GRRF.

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.

32. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2016/35 as amended by GRRF-82-23 proposing editorial corrections to Regulation No. 54. He also introduced ECE/TRANS/WP.29/GRRF/2016/36 proposing amendments to provisions on the minimum markings heights.

33. GRRF agreed with all documents above (see para. 32.) and requested the secretariat to keep the documents on the agenda for the next session.

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.

44. The expert from the Slovak Republic introduced ECE/TRANS/WP.29/GRRF/2015/39 as amended by GRRF-80-16 proposing clarifications for Regulation No. 109. The expert from ETRTO recalled that the proposed clarifications would also be relevant for Regulations Nos. 30 and 54. GRRF agreed to resume consideration of these clarifications on the basis of a revised proposal that the experts from ETRTO and the Slovak Republic volunteered to prepare for the September 2016 session of GRRF.

39. GRRF resumed consideration of proposed amendments to Annexes 7 and 10 to Regulation No. 109 as well as the proposal originally submitted by the expert from Slovakia, in ECE/TRANS/WP.29/GRRF/2016/40. The expert from ETRTO presented a proposal for amendments to tyre marking requirements in ECE/TRANS/WP.29/GRRF/2016/41.

40. GRRF adopted both proposals and requested the secretariat to submit them as draft Supplement 8 to Regulation No. 109 (Retreaded tyres for commercial vehicles and their trailers) to WP.29 and AC.1 for consideration and vote at their March 2017 sessions.

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.

Main content of the document from (F):
Remove CAT D and CAT E from Regulation 79 and install it in a new Regulation. Longitudinal control should not be part of the Regulation 79.

(Chair): In the last WP.29-session, the Chairman of the GRRF (Bernie Frost) reported to the delegates the current work of the IWG ACSF and also, why the group has started with CAT E. It is clear, that the Regulation 79 is not the best “location” for ACSF in total, but to finalize this work in the given timeline, only this approach seem to be the most appropriate. WP.29 did not disagree with this.

(OICA): Proposes to go on with the current working strategy.
(D): All have agreed to go this way, also parking systems are needing braking functions.
(CLEPA): The current way was already confirmed by GRRF.
(see: GRRF-79-31 - (Chair) Guidance to GRs concerning Automated Driving Technology)

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.

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).

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.

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.

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.

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.

General Remark:
All amendments which have been discussed are included in the “consolidated document” ACSF-06-28. The jointly agreed parts of the document are marked in green letters. Amendments, which have been discussed, but finally rejected are removed/excluded from the document. The consolidated document reflects the latest stage of discussion within the group.

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.

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.

13. The expert from CLEPA presented ECE/TRANS/WP.29/GRRF/2016/27, as amended by GRRF-82-03. GRRF supported the aim of this proposal. The proposal received several comments of editorial nature. GRRF agreed to keep both documents on the agenda of the next GRRF session.

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.

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.

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

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.

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.

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.

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.

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.

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.

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

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.

23. GRRF reviewed ECE/TRANS/WP.29/GRRF/2015/41 and GRRF-80-24 under agenda item 5(b) below.

24. The expert from EC introduced ECE/TRANS/WP.29/GRRF/2015/40 and ECE/TRANS/WP.29/GRRF/2015/41, proposing to clarify the possibility to install means to temporarily reduce or disable the ABS function of motorcycles in certain conditions. The expert from Canada submitted an alternative wording (GRRF-80-19) and recalled that an authorization from the Executive Committee AC.3 for developing an amendment to GTR No. 3 would be required. The proposal received some general comments related to road safety. The expert from IMMA briefly introduced GRRF-80-13 commenting the proposals to which the expert from EC responded (GRRF-80-24 and GRRF-80-25). A majority of experts expressed a specific concern related to condition (f). The expert from EC volunteered to prepare two revised proposals for the [February 2016] session of GRRF.

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.

59. Agenda item 4.9.8, Regulation No. 78, ECE/TRANS/WP.29/2016/56, amend to read:
Page 3, the proposed insertion of a new paragraph 5.1.16, shall be deleted.
Page 4, the proposed amendment to paragraph 9, shall be deleted.

82. The World Forum considered the draft proposal for amendments to existing Regulations under agenda item 4.13.1 and recommended its submission to AC.1 for voting subject to the amendments below:

83. Agenda item 4.13.1, in ECE/TRANS/WP.29/2016/114, new paragraph 5.1.16, items (e) and (f), amend to read:
New paragraph 5.1.16, item (e) and (f), amend to read:

“(e) The disablement of the antilock brake system function shall be indicated by the activation of symbol B.18 as specified in ISO 2575:2010 (ISO 7000-2623) or any other equivalent unequivocal indication of the disabled antilock brake system state. Alternatively, the warning lamp referred to in paragraph 5.1.13. shall be continuously activated (i.e. lit or flashing); and

(f) Prohibition of any software and/or hardware defeat device compromising or allowing to circumnavigate one or more of the requirements set out in points (a) to (e); and"

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.

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.

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.

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 endorsed the status report and agreed to resume consideration of this agenda item at its next session.

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.

37. On behalf of CLCCR, the expert from CLEPA proposed amendments to UN Regulation No. 79 (ECE/TRANS/WP.29/GRRF/2013/25) inserting new requirements for trailers with a steering control system utilising electrical energy from the towing vehicle. The proposal received some comments (GRRF-75-11). The expert from Japan noted the absence of a definition for “IP54”. GRRF agreed to resume consideration of this subject at its next session on the basis of a revised proposal.

31. At the request of the author of ECE/TRANS/WP.29/GRRF/2014/8, GRRF agreed to defer this agenda item to its next session.

40. The expert from CLEPA, on behalf of CLCCR, introduced ECE/TRANS/WP.29/GRRF/2014/8 as amended by GRRF-79-02 and GRRF-79-21, aimed at removing a design restriction from Regulation No. 79 that prevents the approval of new technologies. The proposal received some comments. GRRF agreed to resume consideration on this item at its September 2015 session based on a revised proposal that the author volunteered to prepare. The secretariat agreed to consult the Working Party on Lighting and Light-Signalling on the issue of trailer mounted warning light.

54. The expert from CLEPA introduced on behalf of CLCCR the proposal ECE/TRANS/WP.29/GRRF/2015/43 superseding ECE/TRANS/WP.29/GRRF/2015/8. The proposal received some comments and was amended during the session as reproduced in GRRF-80-40. GRRF agreed with the proposal but preferred to review it again in February 2016 in view of a possible adoption in June 2016 by WP.29 and AC.1.54

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.

67. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2015/44 proposing to extend the possibility of actuating the service braking system as described in Regulation No. 89 to vehicles of categories M2 and N2 below 5t. Some experts expressed concerns related to the risk of “hot brakes” phenomena when the (adjustable) speed limitation device would function down hills. The expert from OICA agreed to provide more information about the proposal to be presented at the February 2016 session of GRRF. GRRF agreed to resume consideration on this item at its February 2016 session and requested the secretariat to dedicate an agenda item to Regulation No. 89.
