5. Recalling the adoption at the previous GRSG session of a revised proposal for the introduction of automatic fire suppression systems in the engine and/or heater compartment of buses and coaches and its submission to WP.29 for consideration at the November 2015 session (ECE/TRANS/WP.29/2015/88), the expert from Sweden introduced GRSG-109-02 and GRSG-109-05 proposing to correct some editorial corrections. GRSG endorsed the proposed corrections.

13. GRSG welcomed a presentation by the expert from Hungary on the importance of statistical studies and the collection and evaluation of information on bus accidents (GRSG-109-03 and GRSG-109-26).

17. Referring to the role of his organization, the expert from FIA recalled the purpose of ECE/TRANS/WP.29/GRSG/2015/16 proposing further provisions on the protection against mileage fraud. He introduced GRSG-109-04 justifying the need to establish an informal working group (IWG) on anti-tampering measures for electronic vehicle interfaces, such as odometer, and underlining the need to cope, in a more general manner, with risks of in-vehicle technologies and cyber security. His proposal to set up an IWG received the support of a number of experts. However, some other experts felt it was too premature to set up such an IWG as WP.29 already established, under its IWG on Intelligent Transport Systems (ITS), a subgroup on “Automated Driving” dealing with this subject among others. Therefore, they preferred to start on the basis of an expert group first. The expert from FIA volunteered to organize in the near future a Task Force meeting in Paris. Thus, he invited all interested experts to contact him (lpascotto@fia.com).

16. The expert from FIA gave a presentation (GRSG-108-37) justifying the need for protection against mileage fraud and proposing to set up an informal working group on this subject. He presented ECE/TRANS/WP.29/GRSG/2015/16 proposing further amendments to the proposal submitted by Belgium and inserting a reference to the common criteria published in ISO/IEC 15408 (GRSG-108-06). He concluded that the common criteria would result in a higher level of stringency in the security requirements for odometers and thus improve the protection of odometers against mileage fraud. The expert from India raised concerns (GRSG-108-39) to the proposal from FIA. The expert from OICA introduced GRSG-108-38 clarifying the subject and presenting the concerns of the automotive industry to the proposal from FIA. GRSG experts were invited to send their comments to the expert from FIA. GRSG did not support the adoption of the proposal but agreed to keep ECE/TRANS/WP.29/GRSG/2015/16 and GRSG-108-38 on its agenda as a reference document for further consideration at its next session.

5. Recalling the adoption at the previous GRSG session of a revised proposal for the introduction of automatic fire suppression systems in the engine and/or heater compartment of buses and coaches and its submission to WP.29 for consideration at the November 2015 session (ECE/TRANS/WP.29/2015/88), the expert from Sweden introduced GRSG-109-02 and GRSG-109-05 proposing to correct some editorial corrections. GRSG endorsed the proposed corrections.

38. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2015/29 and Corr.1 aimed at clarifying the scope and updating the reference to ISO standards as well as the test requirements for electric cables in UN Regulation No. 118. The expert from Finland proposed to correct a reference error in Annex 4, Appendix 1 (GRSG-109-06).

39. GRSG adopted both proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2016 sessions, as draft Supplement 2 to the 02 series of amendments to UN Regulation No. 118.

61. GRSG noted the information by the secretariat about the forthcoming workshop for sustainable mobility and the mitigation of climate change, scheduled to be held in Bordeaux (France) on 7 October 2015 (GRSG-109-07).

33. The expert from Japan introduced GRSG-109-08 (superseding ECE/TRANS/WP.29/GRSG/2015/27) proposing to remove from UN Regulation No. 110 the provisions for welded constructions of compressed natural gas (CNG) cylinders or metal liners, including high-strength steel CNG cylinders. The proposal received a number of comments on the need for performance oriented requirements and the transitional provisions. Instead of adopting the proposal as a new 03 series of amendments, GRSG preferred to defer the adoption by WP.29 of the draft 02 series of amendments to UN Regulation No. 110 (currently on the agenda of the November 2015 session of WP.29 as ECE/TRANS/WP.29/2015/90) to its March 2016 session to insert the amendments proposed by Japan. GRSG endorsed the submission of a new consolidated proposal for the 02 series of amendments as reproduced in GRSG-109-22-Rev.1.

34. In this respect, GRSG adopted the proposed text as reproduced in Annex VI to the report. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration at their March 2016 sessions, as a new draft 02 series of amendments to UN Regulation No. 110 (superseding ECE/TRANS/WP.29/2015/90).

40. The expert from Germany also introduced GRSG-109-09 (superseding document ECE/TRANS/WP.29/GRSG/2015/28) proposing to insert, as a further improvement of the provisions of UN Regulation No. 118, new test requirements for electric cables sleeves and cable conduits. The proposal received a general support. The expert from OICA suggested clarifying the proposed text of paragraph 1.2. GRSG agreed to have a final review of the proposed transitional provisions at the next session of GRSG and requested the secretariat to circulate GRSG-109-09, as revised, with an official symbol.

42. Recalling the discussion on this subject at the previous GRSG session, the expert from Germany introduced ECE/TRANS/WP.29/GRSG/2016/3 proposing updated test requirements for electric cables sleeves and cable conduits. The expert from Finland suggested amending also the test provisions of Annex 8 on the test apparatus and the sample dimensions (GRSG-110-02).

43. Following the discussion, GRSG could not give full consent to the proposals and agreed to have a final review of the proposals at the next session of GRSG. Thus, the secretariat was requested to keep both documents on the agenda unless a revised proposal would be submitted.

20. The expert from Hungary presented GRSG-109-10 justifying the amendments to UN Regulation No. 43, proposed in ECE/TRANS/WP.29/GRSG/2015/4 and aimed at clarifying the use of thick glass panes for multiple glazed units. He especially wondered why the headform test was applicable for multiple glazing, but not necessarily for single pans. The expert from Germany explained that the mechanical properties of single pans of safety glazing were different than those of multiple-glazed pans and, therefore, the single pans did not necessarily need to be tested for critical values in case of head impacts. Following the discussion, GRSG agreed to remove ECE/TRANS/WP.29/GRSG/2015/4 from its agenda.

19. The expert from Hungary proposed an amendment to the UN Regulation allowing the use of thick glass panes for multiple glazed units (ECE/TRANS/WP.29/GRSG/2015/4). GRSG noted some comments. The document did not receive the full support of GRSG. It was agreed to keep ECE/TRANS/WP.29/GRSG/2015/4 on the agenda and to have a final review of the proposal at the next session of GRSG.

14. Recalling the purpose of ECE/TRANS/WP.29/GRSG/2015/18 presented at the previous GRSG session, the expert from Germany introduced GRSG-109-11 proposing revised provisions on emergency controls at service doors, specifically on the deactivation of emergency door controls when the vehicle moves to prevent doors from being opened. GRSG adopted ECE/TRANS/WP.29/GRSG/2015/18 as reproduced in Annex III to the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2016 sessions, as part (see paras. 7, 9, 10, 11 and 12 above) of draft Supplement 5 to the 06 series of amendments to UN Regulation No. 107.

27. The expert from AEGPL gave a presentation (GRSG-109-15) justifying the insertion into UN Regulation No. 67 of new provisions to prevent a flow of liquefied petroleum gas (LPG) into the petrol or diesel tank, and vice versa (ECE/TRANS/WP.29/GRSG/2015/35). The expert from Spain raised concerns on the possible interpretation of the new provisions and preferred clear test requirements. The experts from France and Sweden endorsed that position. The expert from Germany introduced GRSG-109-12 proposing some improved text to ECE/TRANS/WP.29/GRSG/2015/35. He raised concerns on the possible leakage of the different fuel types and questioned the need to install redundant valves.

28. Following the discussion, the expert from AEGPL introduced GRSG-109-21 superseding ECE/TRANS/WP.29/GRSG/2015/35. The experts from France and Spain raised a study reservation. Thus, GRSG agreed to resume consideration of this subject at its next session on the basis of a revised proposal by AEGPL, taking into account the comments received.

18. The expert from EC presented GRSG-109-13 proposing to amend the requirements for numeric displays of speedometers. GRSG noted general support of the proposal. The expert from UK stated that some vehicles of category L should be added. GRSG agreed to resume consideration of this subject at its next session on the basis of an official document to be submitted by the expert from EC, taking into account the comments received.

17. The expert from EC introduced GRSG-108-42 proposing to amend the requirements for numeric displays of speedometers. The Chair invited all experts to send their comments to the expert from EC and to resume consideration of the subject at the next GRSG session on the basis of an official document to be submitted by the expert from EC.

12. The expert from EC introduced ECE/TRANS/WP.29/GRSG/2016/25 proposing to adapt the requirements of the Regulation to technical progress and to clarify the specifications for numeric displays of speedometers. The expert from OICA introduced GRSG-111-10 aimed at correcting a reference in footnote ² to paragraph 2.5. of the Regulation.

13. GRSG adopted ECE/TRANS/WP.29/GRSG/2016/25 as amended below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2017 sessions, as draft Supplement 1 to the 01 series of amendments to UN Regulation No. 39.

Paragraph 2.5., footnote ², correct the reference to paragraph 5.3. to read 5.4.

29. The expert from ISO presented GRSG-109-14 on the progress of work within the ISO working group on refueling connector and fuel components for vehicles propelled by Liquefied Natural Gas (LNG). He underlined the request from original equipment manufacturers to update UN Regulation No. 67 with respect to LPG fuel lines and welding requirements.

32. Referring to his presentation (GRSG-109-14) given under agenda item 8 (para. 28 above), the expert from ISO volunteered to submit for the next GRSG session an official document proposing to amend the provisions of Annex 4B of UN Regulation No. 110, including the correction of some errors in Annexes 4A and 4H.

26. Recalling the purpose of ECE/TRANS/WP.29/GRSG/2016/7, the expert from the Netherlands presented GRSG-110-25 amending the provisions of UN Regulation No. 67 on LPG vehicles to allow Class 0/I hoses with couplings using gas tubes other than seamless material. GRSG noted a number of comments on the need for detailed testing specifications for type approval purposes and for clarification of the responsibilities. The Chair of GRSG invited all experts to send their written comments to the expert from the Netherlands. GRSG agreed to resume consideration of this subject at its next session in October 2016 on the basis of an updated official document by the Netherlands taking into account the comments received.

35. The expert from the Netherlands introduced GRSG-110-26 (superseding ECE/TRANS/WP.29/GRSG/2016/8) proposing an amendment to UN Regulation No. 110 to allow Class 0 hoses with couplings using sealing technologies other than those with a 45° cone and, thus, to avoid design restrictive requirements. The proposal received a number of comments.

36. GRSG adopted the proposal as reproduced below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as part (see para. 32 above) of draft Supplement 5 to the 01 series of amendments to UN Regulation No. 110.

Annex 4B, paragraph 1.6.2.2., amend to read:

“1.6.2.2. The interface type for the hose coupling shall be:

(a) sealing cone of swivel-nut type of the type with a half vertical angle of 45°, or
(b) other couplings complying with the tests described in paragraph 1.7., as well as the tests mentioned in Annexes 5A and 5B.

Couplings shall have complementary counterparts."

24. The expert from the Netherlands presented GRSG-111-19 superseding ECE/TRANS/WP.29/GRSG/2016/7 and amending the provisions of UN Regulation No. 67 on LPG vehicles to allow Class 0/I hoses with couplings using gas tubes other than seamless material. The document received a number of comments. GRSG noted study reservations by the experts from Germany and AEGPL. GRSG reviewed the proposal as reflected in GRSG-111-19-Rev.1 and agreed to resume consideration of this subject at its next session in April 2017. The secretariat was requested to circulate GRSG-111-19-Rev.1 with an official symbol.

21. The expert from the Netherlands presented ECE/TRANS/WP.29/GRSG/2017/3 amending the provisions of UN Regulation No. 67 to use non-seamless gas tubes in LPG vehicles. The expert from AEGPL presented GRSG-112-19 inserting some improvements to the proposed provisions. GRSG noted general support and a number of comments. The expert from Germany raised a study reservation. Following the discussion, GRSG agreed to resume consideration of this subject at its next session in October 2017. In this respect, GRSG invited the experts from the Netherlands and AEGPL to prepare a combined document (see para. 20 above), taking into account the comments received and to submit it, in due time, to the secretariat for consideration and final review at the next GRSG session in October 2017.

27. The expert from AEGPL gave a presentation (GRSG-109-15) justifying the insertion into UN Regulation No. 67 of new provisions to prevent a flow of liquefied petroleum gas (LPG) into the petrol or diesel tank, and vice versa (ECE/TRANS/WP.29/GRSG/2015/35). The expert from Spain raised concerns on the possible interpretation of the new provisions and preferred clear test requirements. The experts from France and Sweden endorsed that position. The expert from Germany introduced GRSG-109-12 proposing some improved text to ECE/TRANS/WP.29/GRSG/2015/35. He raised concerns on the possible leakage of the different fuel types and questioned the need to install redundant valves.

28. Following the discussion, the expert from AEGPL introduced GRSG-109-21 superseding ECE/TRANS/WP.29/GRSG/2015/35. The experts from France and Spain raised a study reservation. Thus, GRSG agreed to resume consideration of this subject at its next session on the basis of a revised proposal by AEGPL, taking into account the comments received.

12. The expert from Germany introduced GRSG-109-16 amending the requirements concerning the driver’s view on devices for indirect visions and permitted intrusions, based ECE/TRANS/WP.29/GRSG/2015/14. GRSG adopted the proposed text as reproduced in Annexes III and IV to the report. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration at their March 2016 sessions, as part (see paras. 7, 9, 10 and 11 above) of draft Supplement 5 to the 06 series of amendments and as part (see para. 9) of draft Supplement 5 to the 05 series of amendments to UN Regulation No. 107.

30. Referring to ECE/TRANS/WP.29/GRSG/2015/14, the expert from the Netherlands proposed to also align the provisions of UN Regulation No. 107 with the adopted CMS provisions. The secretariat was requested to submit a proposal, as amended below, to WP.29 and AC.1 for consideration at their November 2015 sessions, as draft Supplement 4 to the 05 series of amendments and as part (see para. 7 above) of draft Supplement 4 to the 06 series of amendments to UN Regulation No. 107.

Paragraph 7.7.1.8.4., amend to read:
“7.7.1.8.4. When the seat …… opposite side of the vehicle or through the centre of any display used as device for indirect vision within the scope of Regulation No. 46, whatever applicable.”

30. Recalling the purpose of GRSG-108-32 presented at the previous session of GRSG as well as the discussion of GRSG under agenda item 7 (para. 24 above) on UN Regulation No. 58, the expert from UK introduced GRSG-109-17 proposing to delete paragraph 1.2.2. from the scope of the Regulation to ensure that as many vehicles as possible were fitted with a lateral protection device. The proposal received general support on the principles. However, a number of experts raised concerns on the application of a number of exemptions for special purpose vehicles listed in the Regulation. GRSG noted that such vehicles could be exempted by national/regional legislation.

31. GRSG agreed to resume consideration of this subject at its next session and requested the secretariat to circulate GRSG-109-17 with an official symbol.

27. The expert from UK reminded GRSG about the purpose of document ECE/TRANS/WP.29/GRSG/2016/2 (based on GRSG-109-17) amending the scope of the Regulation to ensure that as many vehicles as possible were fitted with a lateral protection device. The expert from CLCCR supported the proposal in principle, but preferred to insert derogations for some niche products (GRSG-110-20-Rev.1). GRSG noted a number of comments.

28. GRSG agreed to resume consideration of this subject at its next session and requested the secretariat to keep ECE/TRANS/WP.29/GRSG/2016/2 and GRSG-110-20-Rev.1 on the agenda as reference documents. Thus, the expert from UK volunteered to prepare a revised document for a final review at the forthcoming GRSG session, taking into account the comments received.

26. Recalling the discussion on this subject (GRSG-108-47) at the previous session of GRSG, the expert from IMMA introduced GRSG-109-18 amending the requirements for the identification of controls, tell-tales and indicators on two-wheeled motorcycles and mopeds. He underlined the urgent need to align in this way the provisions of UN Regulation No. 60 with those of UN Regulation No. 121. On an exceptional basis, GRSG adopted the proposal as reproduced in Annex V to the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as draft Supplement 5 to UN Regulation No. 60, subject to a final review by GRSG at its next session in April 2016.

67. The expert from IMMA introduced GRSG-108-47 proposing to amend the requirements for identification of controls, tell-tales and indicators on two-wheeled motor cycles and mopeds. GRSG noted a number of concerns. The Chair invited all experts to send their comments to the expert from the IMMA. GRSG agreed to resume consideration of this subject at its next session on the basis of a revised document.

68. The World Forum agreed to defer the draft amendment under agenda item 4.15.1 to its June 2016 session awaiting the results of a final review by GRSG.

16. The expert from Japan, chairing the new Informal Working Group (IWG) on awareness of Vulnerable Road Users proximity in low speed manoeuvres (VRU-Proxi), reported on the progress made by the group during its meeting in Brussels on 23-24 March 2017 (GRSG-112-13). GRSG welcomed the updated draft terms of reference and rules of procedure for the IWG on VRU-Proxi (GRSG-112-14-Rev.1 superseding GRSG-111-29). GRSG noted the overlap of the IWG activities with agenda item 16 on a new draft UN Regulation on Blind Spot Information Systems (BSIS). GRSG underlined the urgent need to adopt the new UN Regulation and agreed that the IWG on VRU-Proxi shall consider ECE/TRANS/WP.29/GRSG/2017/11 (tabled by Germany) as a first priority at its forthcoming meeting, scheduled to be held in Paris on 3-4 July 2017. In this respect, GRSG adopted the terms of reference and rules of procedure for the IWG on VRU-Proxi as reproduced in Annex III to this report. The GRSG Chair announced his intention to inform WP.29 at its June 2017 session about the terms of reference of the above-mentioned IWG.

47. The expert from Germany presented GRSG-112-36 on the development of test procedures for a new draft UN Regulation on Blind Spot Information Systems (BSIS). He reported on the research results, the derivation of test cases and the new technical requirements on the conduction of test for such BSIS. He introduced a proposal for a new draft UN Regulation on BSIS (ECE/TRANS/WP.29/GRSG/2017/11). GRSG welcomed the detailed information and the proposal by Germany.

48. The expert from Israel recommended to extend the scope also to categories of vehicles other than N₂ and N₃. He added to even insert provisions on aftermarket BSIS for the purpose of retrofitting vehicles already in service. A number of experts underlined their preference to adopt, in a first step, the new UN Regulation and then to extend the scope in a further stage.

49. During a first reading of ECE/TRANS/WP.29/GRSG/2017/11, the document received a number of comments on the definitions and cross-references to other UN Regulations. Following the discussion, GRSG agreed that the IWG on VRU-Proxi (see para. 16 under agenda item 5) shall resume consideration of ECE/TRANS/WP.29/GRSG/2017/11 as a first priority at its forthcoming meetings.

50. GRSG agreed to, at its next session, have a further review of draft UN Regulation on BSIS and to resume consideration of ECE/TRANS/WP.29/GRSG/2017/11 on the basis of the detailed feedback by the IWG on VRU-Proxi.

24. The expert from Japan gave a presentation on the results of a national study on fatal accidents of pedestrians with motor vehicles at low speed (GRSG-109-20). He concluded that a possible solution to avoid such accidents could be new requirements to ensure the driver’s view on the proximity area of his vehicle. On behalf of the Task Force (TF) on UN Regulation No. 46, he reported on the progress made during the recent TF meeting held prior to the GRSG session. He informed GRSG about the TF decision to go forward with a two-step approach: (i) fully harmonize UN Regulation No. 46 without the close proximity vision area and (ii) subsequently develop new requirements for the close proximity vision area. He announced the intention of Japan to continue to further study accident data and to share the results with the TF. GRSG welcomed the detailed information received. GRSG endorsed the decision of the TF and agreed to resume consideration of this subject at its next session in April 2016.

27. The expert from AEGPL gave a presentation (GRSG-109-15) justifying the insertion into UN Regulation No. 67 of new provisions to prevent a flow of liquefied petroleum gas (LPG) into the petrol or diesel tank, and vice versa (ECE/TRANS/WP.29/GRSG/2015/35). The expert from Spain raised concerns on the possible interpretation of the new provisions and preferred clear test requirements. The experts from France and Sweden endorsed that position. The expert from Germany introduced GRSG-109-12 proposing some improved text to ECE/TRANS/WP.29/GRSG/2015/35. He raised concerns on the possible leakage of the different fuel types and questioned the need to install redundant valves.

28. Following the discussion, the expert from AEGPL introduced GRSG-109-21 superseding ECE/TRANS/WP.29/GRSG/2015/35. The experts from France and Spain raised a study reservation. Thus, GRSG agreed to resume consideration of this subject at its next session on the basis of a revised proposal by AEGPL, taking into account the comments received.

25. The expert from AEGPL introduced GRSG-110-13, superseding his proposal ECE/TRANS/WP.29/GRSG/2015/35 and proposing new provisions to prevent a flow of liquefied petroleum gas (LPG) into the petrol or diesel tank, and vice versa. GRSG noted general support on the updated proposal. Following a study reservation by the expert from France, GRSG decided to have a final review of the proposal at its next session in October 2016 and requested the secretariat to circulate GRSG-110-13 with an official symbol.

[Postponed until June 2016 session in order to integrate the contents with additional provisions under development within the GRSG.]

31. The GRSG chair recalled that GRSG had already adopted at its previous session in May 2015 a new 02 series of amendments proposing provisions on a directional discharge of the pressure relief devices of CNG containers (submitted as ECE/TRANS/WP.29/2015/90 to the November 2015 session of WP.29). He added that GRSG had just adopted another amendment removing the provisions on welded cylinders and raising again the stringency of Regulation No. 110. Instead of adopting that amendment as a further new series of amendments, GRSG had agreed to remove ECE/TRANS/WP.29/2015/90 from the WP.29 agenda in November 2015 and to submit a new draft 02 series of amendments to UN Regulation No. 110, incorporating both proposals (directional discharge and removal of welded cylinders) for consideration at the March 2016 session of WP.29.

61. The consideration of ECE/TRANS/WP.29/2015/90 tabled under agenda item 4.7.9 was deferred to the March 2016 session of WP.29 (see para. 31 above).

33. The expert from Japan introduced GRSG-109-08 (superseding ECE/TRANS/WP.29/GRSG/2015/27) proposing to remove from UN Regulation No. 110 the provisions for welded constructions of compressed natural gas (CNG) cylinders or metal liners, including high-strength steel CNG cylinders. The proposal received a number of comments on the need for performance oriented requirements and the transitional provisions. Instead of adopting the proposal as a new 03 series of amendments, GRSG preferred to defer the adoption by WP.29 of the draft 02 series of amendments to UN Regulation No. 110 (currently on the agenda of the November 2015 session of WP.29 as ECE/TRANS/WP.29/2015/90) to its March 2016 session to insert the amendments proposed by Japan. GRSG endorsed the submission of a new consolidated proposal for the 02 series of amendments as reproduced in GRSG-109-22-Rev.1.

34. In this respect, GRSG adopted the proposed text as reproduced in Annex VI to the report. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration at their March 2016 sessions, as a new draft 02 series of amendments to UN Regulation No. 110 (superseding ECE/TRANS/WP.29/2015/90).

25. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2015/8 on new provisions for the indirect view within UN Regulation No. 125 (Forward field of vision of drivers) in the case vehicles were equipped with CMS. GRSG noted some comments. The expert from OICA clarified that only the devices for indirect vision covered by UN Regulation No. 46 shall benefit from such provisions (GRSG-108-25). The expert from Germany volunteered to prepare an updated document for consideration at the next GRSG session, taking into account the comments received.

45. The expert from Germany presented GRSG-109-23-Rev.1 (superseding document ECE/TRANS/WP.29/GRSG/2015/8) introducing new requirements for the indirect view of the driver in case vehicles were equipped with camera-monitor systems. GRSG adopted ECE/TRANS/WP.29/GRSG/2015/8 as reproduced in Annex VII and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2016 sessions, as draft Supplement 1 to the 01 series of amendments to UN Regulation No. 125.

46. In this respect, GRSG intended to promote the introduction of camera-monitor systems (CMS) in vehicles of category M1 also by allowing for a temporary period an obstruction in the direct field of view of the driver by the installation of a monitor in place of a mirror. GRSG agreed to remove this temporary exemption such that the Contracting Parties shall not be obliged to accept, as from 1 September 2021, approvals based on the new paragraph 5.1.3.2. of UN Regulation No. 125.

47. The expert from the Russian Federation, chairing the IWG on AECS, reported on the work results achieved by the group (GRSG-109-24). He informed GRSG about the decision of the IWG to limit the scope of the new draft UN Regulation on AECS, not covering the telecommunication functionalities. He added that the IWG would resume consideration of the manual triggering of the AECS. In this respect, he sought the advice of GRSG on the possibility to switch-off AECS and to mandate or permit in the installation requirements a switch-off button. He announced the intention of the IWG to submit a first proposal of the draft UN Regulation at the next GRSG on the basis of an informal document.

48. With respect to the possibility to switch-off AECS, GRSG was of the opinion to permit the installation of a switch-off button only in very limited cases, e.g. maintenance purposes, and not directly accessibly from the passenger compartment. The expert from EC informed GRSG on the still ongoing discussion in his organization on the same question but related to the European Union “eCall” system. He offered to keep GRSG and AECS informed once an agreement was found in Brussels.

49. As the mandate of the IWG on AECS was limited to October 2015 and due to the delay in the development of the new Regulation, the AECS Chair requested an extension of the mandate by one year, until October 2016. GRSG endorsed that request. The Chair of GRSG announced his request to seek the endorsement of WP.29 at the forthcoming November session.

50. GRSG recalled its discussion under agenda item 14 (paras. 42-43 above) on a new symbol for the emergency call control and tell-tale. Finally, GRSG agreed to resume consideration of this subject at its next session, awaiting a first proposal of the draft UN Regulation on AECS.

51. The expert from OICA, in his capacity of GRSG Ambassador to the IWG on IWVTA, informed GRSG about the progress made during the recent meetings of the IWGs (GRSG-109-25). He recalled the remaining open issue of the clarification of the scope of UN Regulation No. 116 (GRSG-104-39-Rev.3 and GRSG-108-49).

52. A number of experts were of the opinion that the installation on vehicles of categories M1 and N1 of an immobilizer or antitheft devices was mandatory, but the installation of the alarm systems was considered as optional. As paragraph 1.8. of UN Regulation No. 116 (including its recommendation under footnote 3/) was subject to the choice of application by the Contracting Parties and therefore not clear, GRSG welcomed the suggestion by the expert from OICA to set up a specific Task Force to clarify this subject. The Chair invited all interested experts to contact the GRSG Ambassador (e-mail: ofontaine@oica.net). GRSG agreed to resume consideration of this subject at its next session in April 2016.

13. GRSG welcomed a presentation by the expert from Hungary on the importance of statistical studies and the collection and evaluation of information on bus accidents (GRSG-109-03 and GRSG-109-26).

“2.5.4. At the moment of collision the velocity of the centre of percussion of the pendulum shall be between 48 and 52 km/h.”

64. The expert from Japan proposed to amend the requirements for fire prevention under certain conditions in the event of a rear collision (GRSG-108-12). GRSG welcomed the proposal and agreed to resume consideration of this subject at its next session in October 2015 on the basis of an official document.

16. The expert from India introduced ECE/TRANS/WP.29/GRSG/2015/26 proposing to harmonize the scope of UN Regulation No. 34 and to amend the total permissible mass limit to read “2.5 tonnes” instead of “2.8 tonnes”. The expert from Japan raised concerns in the absence of evidence on the need for such an amendment. GRSG endorsed the suggestion by the expert from EC to review the proposal by India, once the application of the 03 series of amendments to UN Regulation No. 34 would become mandatory in the European Union. GRSG agreed to remove, in the meantime, this item from the agenda.

65. The expert from India presented GRSG-108-41 proposing to harmonize the scope of UN Regulation No. 34 and to amend the total permissible mass limit to read “2.5 tonnes” instead of “2.8 tonnes”. The expert from Japan was of the opinion that this amendment would lower the stringency of the provisions of the UN Regulation and, therefore, could not support the proposal. GRSG agreed to resume consideration of this subject at its forthcoming session and requested the secretariat to distribute GRSG-108-41 with an official symbol.

33. The expert from Japan introduced GRSG-109-08 (superseding ECE/TRANS/WP.29/GRSG/2015/27) proposing to remove from UN Regulation No. 110 the provisions for welded constructions of compressed natural gas (CNG) cylinders or metal liners, including high-strength steel CNG cylinders. The proposal received a number of comments on the need for performance oriented requirements and the transitional provisions. Instead of adopting the proposal as a new 03 series of amendments, GRSG preferred to defer the adoption by WP.29 of the draft 02 series of amendments to UN Regulation No. 110 (currently on the agenda of the November 2015 session of WP.29 as ECE/TRANS/WP.29/2015/90) to its March 2016 session to insert the amendments proposed by Japan. GRSG endorsed the submission of a new consolidated proposal for the 02 series of amendments as reproduced in GRSG-109-22-Rev.1.

34. In this respect, GRSG adopted the proposed text as reproduced in Annex VI to the report. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration at their March 2016 sessions, as a new draft 02 series of amendments to UN Regulation No. 110 (superseding ECE/TRANS/WP.29/2015/90).

27. The expert from Japan introduced GRSG-107-09 and GRSG-107-37, informing GRSG about the outcome of a “Study group for CNG cylinders” established in Japan for investigation of safety related issues in UN Regulation No. 110.

43. The expert from Japan suggested amending UN Regulation No. 110 to improve the safety provisions for CNG and Liquefied Natural Gas (LNG) containers (GRSG-108-11). He expressed his preference to remove all provisions for welded metal cylinders. The expert from the Netherlands preferred to insert a clear provision to exclude such cylinders from the scope of the UN Regulation. The expert from EC stressed the need to also review the marking provisions of cylinders. GRSG welcomed the proposal and agreed to resume consideration of this subject at its next session on the basis of a revised proposal by Japan.

40. The expert from Germany also introduced GRSG-109-09 (superseding document ECE/TRANS/WP.29/GRSG/2015/28) proposing to insert, as a further improvement of the provisions of UN Regulation No. 118, new test requirements for electric cables sleeves and cable conduits. The proposal received a general support. The expert from OICA suggested clarifying the proposed text of paragraph 1.2. GRSG agreed to have a final review of the proposed transitional provisions at the next session of GRSG and requested the secretariat to circulate GRSG-109-09, as revised, with an official symbol.

31. The expert from OICA introduced detailed justifications (GRSG-107-18) for his proposal (ECE/TRANS/WP.29/GRSG/2014/24) to update, in UN Regulation No. 118, the ISO standard references. GRSG agreed to resume discussion on this agenda item at its May 2015 session and to keep GRSG-107-18 as reference, to leave time for experts to study ISO STD 6722 (see para. 26 above). Experts were invited to send comments to the secretariat concerning the above-mentioned ISO standard.

50. Recalling the purpose of his justification document GRSG-107-18, the expert from OICA introduced ECE/TRANS/WP.29/GRSG/2014/24 updating the provisions on the cable test, especially the reference to international standard ISO 6722 (available in GRSG-107-28). The expert from Germany presented additional test requirements for cables (GRSG-108-09). The expert from OICA supported in principle the more stringent test requirements proposed by Germany, but raised a reservation to study the possible need for transitional provisions.

51. GRSG agreed to resume consideration of this subject at its next session on the basis of an official document, jointly prepared by Germany and OICA, including a proposal for transitional provisions, if necessary.

42.

43. Following the discussion, GRSG could not give full consent to the proposals and agreed to have a final review of the proposals at the next session of GRSG. Thus, the secretariat was requested to keep both documents on the agenda unless a revised proposal would be submitted.

38. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2015/29 and Corr.1 aimed at clarifying the scope and updating the reference to ISO standards as well as the test requirements for electric cables in UN Regulation No. 118. The expert from Finland proposed to correct a reference error in Annex 4, Appendix 1 (GRSG-109-06).

39. GRSG adopted both proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2016 sessions, as draft Supplement 2 to the 02 series of amendments to UN Regulation No. 118.

50. Recalling the purpose of his justification document GRSG-107-18, the expert from OICA introduced ECE/TRANS/WP.29/GRSG/2014/24 updating the provisions on the cable test, especially the reference to international standard ISO 6722 (available in GRSG-107-28). The expert from Germany presented additional test requirements for cables (GRSG-108-09). The expert from OICA supported in principle the more stringent test requirements proposed by Germany, but raised a reservation to study the possible need for transitional provisions.

51. GRSG agreed to resume consideration of this subject at its next session on the basis of an official document, jointly prepared by Germany and OICA, including a proposal for transitional provisions, if necessary.

53. The expert from IMMA rapidly introduced ECE/TRANS/WP.29/GRSG/2015/30 proposing to insert into the R.E.3 a definition of “twinned wheels”. He added that his organization was still considering the categories of vehicles concerned and he suggested deferring the discussion on this subject. He announced the submission of an informal document with further details for consideration at the next GRSG session.

57. The expert from IMMA introduced GRSG-108-18 proposing to insert into the R.E.3 a definition of “twinned wheels”. Japan raised a study reservation. GRSG noted some comments and agreed to resume consideration of this subject at its next session in October 2015 on the basis of a new proposal by IMMA, taking into account the comments received.

65. The expert from IMMA introduced GRSG-115-12, in reference to ECE/TRANS/WP.29/GRSG/2015/30, which amend the provisions of R.E.3 to allow the application of “twinned wheels” on all vehicles of category L. The expert from EC suggested reading in the proposed paragraph 2.1.1. “twinned wheels configuration” instead of “twinned wheels”. A number of experts endorsed the proposal. GRSG agreed to resume consideration of this subject at its next session and requested the secretariat to circulate GRSG-115-12 with an official symbol.

9. The expert from Germany also introduced ECE/TRANS/WP.29/GRSG/2015/31 correcting an error in the text of Regulation No. 107 and restricting the mandatory application of the requirements on pram spaces to vehicles of Class I.

The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration at their March 2016 sessions, as part (see para. 7 above) of draft Supplement 5 to the 06 series of amendments and draft Supplement 5 to the 05 series of amendments to UN Regulation No. 107.

6. Upon the request of GRSG at its previous session, the expert from OICA presented ECE/TRANS/WP.29/GRSG/2015/32 aimed at mandating fire suppression systems on vehicles of Classes I and II as a new 07 series of amendments to UN Regulation No. 107. GRSG noted a number of concerns by France, Germany, Italy, Poland, United Kingdom, IRU and UITP on the scope and the proposed transitional provisions. Recalling its commitment of the last session (ECE/TRANS/WP.29/GRSG/87, para. 6), GRSG adopted ECE/TRANS/WP.29/GRSG/2015/32 as reproduced in Annex II to the report and requested the secretariat to submit the proposal to WP.29 and AC.1 for consideration at their March 2016 sessions, as draft 07 series of amendments to UN Regulation No. 107.

5. Recalling the discussion at the previous GRSG session, the expert from Sweden introduced a revised proposal for the introduction of automatic fire suppression systems in the engine and/or heater compartment of buses and coaches (ECE/TRANS/WP.29/GRSG/2014/6/Rev.1). The expert from OICA raised concerns and presented GRSG-108-45 proposing further improvements to the revised text. The expert from Hungary introduced GRSG-108-10 on statistical information about fires in different categories and classes of buses and coaches.

6. Following a controversial discussion on the scope of the new test requirement for automatic fire suppression systems, GRSG agreed to go forward with the following compromise stages: (i) to agree during the current session on the mandatory installation of such systems on vehicles of Class III (as a Supplement to the 06 series of amendments) taking into account the transitional provisions (i.e. June 2018 for new types of vehicles and June 2019 for all existing types) as reflected in GRSG-108-51 and (ii) to reach a consensus at the forthcoming session of GRSG on the mandatory installation of automatic fire suppression systems on vehicles of Classes I and II. Thus, GRSG already committed to the following dates for the transitional provisions of stage (ii) mentioned above: at the latest 2020 for new types and 2022 for all types.

7. Finally, GRSG adopted ECE/TRANS/WP.29/GRSG/2014/6/Rev.1, as amended as reproduced in GRSG-108-51, and requested the secretariat to submit the proposal to WP.29 and AC.1 for consideration at their November 2015 sessions, as draft Supplement 4 to the 06 series of amendments to UN Regulation No. 107.
