3. GRSG also adopted the running order for the session as proposed by the Chair in GRSG-112-01-Rev.1. GRSG noted the main decisions and recommendations of the World Forum WP.29 taken during its November 2016 and March 2017 sessions (see reports ECE/TRANS/WP.29/1126 and ECE/TRANS/WP.29/1129).

Proposal to address the concerns raised in document GRSG-111-35 (which failed to achieve consensus at the last GRSG session) through application of FprEN 16584-1:2015 and 2:2015, respectively referring to requirements for color contrast for signage and quality of audible information.

5. Recalling the discussion at the previous GRSG session on ECE/TRANS/WP.29/GRSG/2016/20, the expert from Switzerland presented GRSG-112-02-Rev.1 proposing to simplify the provisions of UN Regulation No. 107 by inserting references to parts 1 and 2 of the forthcoming updated European standards EN 16584:2015 on railway applications for persons with reduced mobility (GRSG-112-03 and GRSG-112-04). The expert from France preferred to leave these requirements out of the Regulation to avoid possible inconsistencies with existing national requirements. A number of experts preferred to keep some of the requirements proposed in GRSG-111-35 within the Regulation, but to improve the wording of the provisions concerned. Following the discussion, GRSG adopted ECE/TRANS/WP.29/GRSG/2016/20 as amended by GRSG-112-35 and agreed to submit it to WP.29 as a new 08 series of amendments to UN Regulation No. 107. Thus, the expert from OICA volunteered to prepare, in due time, a revised official document for consideration and final adoption at the next GRSG session, including the proposed transitional provisions (i.e. June 2020 for new types of vehicles and June 2022 for all existing types).

28. The expert from ISO presented GRSG-112-38 justifying the need to harmonize the requirements on Compressed Natural Gas (CNG) and/or Liquefied Natural Gas (LNG) vehicles in UN Regulation No. 110 with those in the latest version of ISO 11439:2013 (as proposed in ECE/TRANS/WP.29/GRSG/2016/22). He recalled the comments received by GRSG experts during the last sessions (mainly on GRSG-111-02-Rev.1 and GRSG-112-05) and announced his intention to prepare, in due time, a revised official document for consideration at the next GRSG sessions, including transitional provisions.

Presentation concerning ISO vehicle propulsion energy identification standardization.

31. The expert from the International Association of Fire and Rescue Services (CTIF) gave a presentation (GRSG-112-06) on the need to harmonize the identification of propulsion and energy storage systems in vehicles to reduce the risks for rescuers during their interventions in case of severe road accidents. He informed GRSG about their cooperation with ISO on this subject and the work progress done. He expected that the new standard ISO 17840‐4 would be published in near future. He underlined that the location or position of labels on the vehicle or in the emergency response guide was outside the scope of the ISO standard. Thus, he sought the advice of GRSG experts on how to address this problem within the UN vehicle regulations. GRSG welcomed the information and had a detailed exchange of views on the best way to move forward, either as amendments to existing UN regulations or as a new guideline document to be annexed to one or the other resolutions on the construction of vehicles. Following the discussion, GRSG preferred to wait for the final publication of the ISO standard and invited the expert from CTIF to prepare in the meantime concrete proposals for possible amendments to UN Regulations Nos. 67 (LPG vehicles), 100 (Electric power trained vehicles), 110 (CNG/LNG vehicles), 134 (Hydrogen and Fuel Cell Vehicles) and the new UN Regulation on AECS. GRSG agreed to resume consideration of this item at its next session in October 2017.

Proposal for editorial corrections to align the definition on plastic glazing between the original English version and the French translation as well as of the communication annex on principal/secondary characteristics for laminated-glass windscreens.

13. The expert from France proposed to align the French and English version of Revision 3 of UN Regulation No. 43 (GRSG-112-07-Rev.1). GRSG adopted the proposal as reproduced in Annex II to this report and requested the secretariat to submit it to WP.29 and AC.1 as Corrigendum 6 to Revision 3 and as Corrigendum 1 to Revision 4 of UN Regulation No. 43 for consideration at their November 2017 sessions.

Proposal to align the communication form with with the scope of the Regulation regarding vehicle categories (adding category L).

17. Recalling the discussion in GRSG at its previous session, the expert from Germany introduced ECE/TRANS/WP.29/GRSG/2017/2 proposing to correct the provisions of paragraph 16.1.3.1. on the magnification factor. He also introduced GRSG-112-30 correcting a reference error in paragraph 6.3.3.2. The expert from France proposed to insert an editorial amendment to the communication form in Annex 4 (GRSG-112-08). GRSG adopted ECE/TRANS/WP.29/GRSG/2017/2 as amended below and requested the secretariat to submit it to WP.29 and AC.1 as draft Supplement 5 to the 04 series of amendment to UN Regulation No. 46 for consideration at their November 2017 sessions.

Paragraph 6.3.3.2., correct the reference to “paragraph 6.1.3.” to read “paragraph 6.1.1.3.”.
Annex 4, item 4., amend to read:
“4. Category of vehicle: (M1, M2, M3, N1, N2 ≤ 7.5 t, N2 > 7.5 t, N3, L) ²”

In the English version of UN Regulation No. 34, the provisions for lateral collision are referenced in para. 1.2. of the scope and in para. 9 of Part II on vehicle tests, but (unlike in the French translation) they are not mentioned in para. 5.10. on the test requirements for liquid fuel tanks. This proposal aims to align the English version to French text of the Regulation with regard to the test provisions for side impacts.

51. The expert from France introduced GRSG-112-09 to align the English version to the French text of the Regulation with respect to the test provisions for side impacts. The expert from the Russian Federation confirmed that the Russian version of the text concerned would have to be aligned too. Referring to GRSG-112-26, the expert from OICA suggested introducing further improvements to the proposed amendments. GRSG noted some general support. The expert from Japan raised a study reservation. GRSG agreed to resume consideration of this subject at its next session in October 2017 on the basis of a revised official document jointly prepared by the experts from France and OICA.

Proposal to exempt any heaters (and not only combustion heaters as in the current text) located outside the passenger compartment and using water as a transfer medium are deemed to comply with the annexes on air quality and temperature.

52. The expert from France presented GRSG-112-10 aimed at clarifying the application of annexes on heaters located outside the passenger compartment and using water as a transfer medium. GRSG agreed to take a final position on this subject at its next session. Thus, the secretariat was requested to circulate GRSG-112-10 with an official symbol.

Proposal to change the measuring units for vehicle masses used in RE3 from tonnes to kilograms in R.E.3.

53. The expert from the Russian Federation introduced GRSG-112-11 on a proposal endorsed by the Working Party on Noise (GRB) to adapt in R.E.3 the measuring units for vehicle masses from tonnes to kilograms. GRSG endorsed the proposal in principle. The secretariat suggested to also aligning in R.E.3 some sub-categories of vehicles, such as L_1A for powered cycles and L_1B for two-wheeled mopeds. The expert from EC volunteered to prepare a comparison document between the categories listed in EU Regulation No. 168/2013 and those in Revision 5 of R.E.3. GRSG noted general support and agreed to circulate GRSG-112-11 with an official symbol for consideration at its next session.

Proposal to clarify the text. Supplement 1 to the 02 series of amendments amended the definition of the interior compartment (formerly “passenger compartment” up to the 01 series of amendments). Part of this amendment concerned the upper boundary surface, replacing the term “roof” by “ceiling”. This proposal updates several passages of the text where the term “roof” should therefore be replaced.

54. The expert from Germany proposed to align in UN Regulation No. 118 the wording for the upper boundary surface by replacing “roof” by “ceiling” (GRSG-112-12). GRSG noted general support and agreed to resume consideration at its next session on the basis of an official document.

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.

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.

Updated amendments from the AECS informal group based on GRSG/2017/12 to refine the draft regulation on AECS under consideration by GRSG.

40. The expert from the Russian Federation, chairing the IWG on AECS, presented an updated proposal of draft UN Regulation on AECS (ECE/TRANS/WP.29/GRSG/2017/12). As Secretary of the IWG on AECS, the expert from OICA introduced GRSG-112-15 proposing some further editorial corrections to ECE/TRANS/WP.29/GRSG/2017/12. The expert from the Russian Federation introduced GRSG-112-27 clarifying mainly the scope and definitions of the draft UN Regulation. She informed GRSG that from, a technical point of view, the corridor of sled pulse (60g) specified in ECE/TRANS/WP.29/GRSG/2017/12 was severe enough, but taking into account the importance and urgency for the adoption of the new UN Regulation by all Contracting Parties, the Russian Federation would support the more stringent corridor (65g) in line with the EU legislation. The expert from OICA reiterated a concern about the economic burden for technical services and laboratories offering the more stringent tests due to the considerable costs of test equipment performing such acceleration/declaration of 65g.

41. Following a detailed consideration of ECE/TRANS/WP.29/GRSG/2017/12, GRSG adopted the new UN Regulation on AECS as reproduced in GRSG-112-42, subject to a final review at its October 2017 session of the official translations into the French and Russian languages. The GRSG Chair thanked again for the excellent work done by the IWG and for the acceptance by the Russian Federation to support the final proposal. The secretariat was requested to submit the adopted proposal to WP.29 and AC.1 as new draft UN Regulation on AECS for consideration at their November 2017 sessions, subject to a final review at the forthcoming GRSG session.

Proposal to replace the prohibition against the use of reinforced insulation for trolleybus circuits directly connected to the overhead power line with a requirement that such circuits shall be double insulated.

6. The expert from the Czech Republic introduced GRSG-112-16 to improve the safety requirements for trolleybuses, particularly the double insulation of circuits directly connected to the overhead lines. GRSG welcomed the proposal and agreed to resume consideration of this subject at its next session on the basis of an official document.

Question on whether it is possible to approve a vehicle declared for no standing passengers as a Class II bus (as opposed to requiring approval as Class III which is specifically defined as a bus designed to carry only seated passengers).

7. The expert from Spain sought the advice of GRSG experts on how to approve a vehicle with no standing passengers (GRSG-112-17). He was of the opinion that, according to UN Regulation No. 107, such a vehicle should be considered as a Class III vehicle only. GRSG endorsed that position.

Marked up revision of RE3-Rev.5

44. The secretariat reported on the recent adoption by WP.29 of the guideline on cybersecurity and data protection (ECE/TRANS/WP.29/2017/46), submitted by the IWG on Intelligent Transport Systems (ITS) and on its decision to include the guideline as a new annex to the Consolidated Resolution on the Construction of Vehicles (R.E.3.). In this respect, GRSG noted draft Revision 5 of R.E.3 (GRSG-112-18) and endorsed it.

Proposal to allow for the approval of systems using non-seamless double and single wall tubes subject to testing for high pressure and high resistance to pressure pulses. The proposal would also add general test requirements for LPG fuel lines and couplings based on ISO Standard 15500 for compressed natural gas equipment.

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.

In GRSG/2017/10, Poland proposes requirements for the LPG tank and its accessories. AEGPL notes that UN R67 requires a specific bonfire test of the container equipped with specific configurations of accessories which includes markings to indicate the extension number of each accessory corresponding to each configuration. In order to ensure that the user knows whether an accessory can be fitted with a specific container, AEGPL proposes to require marking the extension number on the accessories relevant to the bonfire test (multivalve, pressure relief valve and pressure relief device) in order to prevent/forbid the fitting of any accessory not approved for use in each container configuration. This alternative proposal to that in GRSG/2017/10 would imply a new marking requirement for accessories, but would avoid the proliferation of accessory type-approval numbers and increase in paperwork.

22. The expert from Poland gave a presentation (GRSG-112-37) justifying his proposal ECE/TRANS/WP.29/GRSG/2017/10 to clarify the provisions for type approved accessories fitted to LPG containers. The proposal received some support. The expert from AEGPL presented GRSG-112-20 proposing, as an alternative, the additional marking of the accessories with the number of type approval extension. Following a controversial discussion, the expert from Poland proposed to set up either a task force or a new informal working group on gaseous fuelled vehicles to work on the best solution. His proposal to establish an IWG did not receive full support. Finally, GRSG agreed to resume consideration of this subject at its next session in October 2017 on the basis of a new proposal jointly prepared by Poland and AEGPL. Thus, GRSG invited all interested experts to send them, in due time, their written comments.

Proposal to introduce tolerances for dish, bayonet, and acme filling units in order to reduce risks of misuse in connecting these filling units with nozzles.

23. The expert from AEGPL presented GRSG-112-21 introducing tolerances for the dimensions of some filling units. A number of experts preferred to insert the corresponding specifications into the text of the UN Regulation instead of a reference to standard EN 22768-1. GRSG invited the expert from AEGPL to submit, in due time, an updated proposal for consideration at the next session of GRSG in October 2017.

Proposal to introduce a maximum service life requirement of 15 years and for the location of the filling unit of the LPG tank on vehicles.

24. The expert from Turkey introduced GRSG-112-22 proposing to develop new provisions on the location on the vehicle of the filling unit and a limitation of the service life of containers. A number of experts welcomed the initiative. GRSG invited the expert from Turkey to prepare a proposal for consideration at the next session of GRSG in October 2017.

Proposal to align UN R121 with the 07 series of amendments to UN Regulation No. 16:

1. the term “seat belt” is replaced by “safety belt”,
2. the symbol for safety belt, defined in item 21 of Table 1 in the Regulation, may be displayed in different colours to convey different meanings. Therefore, the existing footnote 18 has been added to item 21, and
3. this symbol may be replaced by different symbols for seats other than those of the front row. Therefore, a new footnote 22 is added to item 21.

37. The expert from OICA presented GRSG-112-23 (superseding ECE/TRANS/WP.29/GRSG/2017/5) to align the provisions of UN Regulation No. 121 to those of the 07 series of amendments to UN Regulation No. 16 on safety belts. GRSG adopted the proposal as reproduced in Annex IV to the session report and requested the secretariat to submit it to WP.29 and AC.1 as part (see para. 36 above) of draft Supplement 2 to the 01 series of amendment to UN Regulation No. 121 for consideration at their November 2017 sessions.

Proposal to clarify that in the case where telltale No. 1 (Master lighting switch) and telltale No. 19 (Position, side marker, and/or end-outline marker lamps) are combined, the symbol may be shown in other colours than specified in the table of telltales in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004 (i.e., per footnote 18 to the table).

39. The expert from OICA introduced GRSG-112-24 to clarify the application of footnote ¹⁸ in the case where tell-tales Nos. 1 and 19 were combined. Some experts were of the opinion that footnote ¹² already offers that possibility and that the proposed amendment was superfluous. GRSG agreed to take a final position on this subject at its next session and requested the secretariat to circulate GRSG-112-24 with an official symbol.

Proposal to correct the translation into Russian of Table 1 in document GRSG/2017/5.

38. The expert from the Russian Federation underlined the need to correct the Russian version of ECE/TRANS/WP.29/GRSG/2017/5 in line with the English text (GRSG-112-25). GRSG requested the secretariat to take into account the correction of the Russian translation when preparing the above mentioned official document.

Proposal to clarify provisions concerning protection of the fuel tank in the event of vehicle collision in connection with the proposal by France in document GRSG-112-09 to align the French translation with the English original. The intent is to clarify the prohibition against the presence of elements likely to cause damage to the installed tank in the event of a collision rather than to the installation of the tank per se.

51. The expert from France introduced GRSG-112-09 to align the English version to the French text of the Regulation with respect to the test provisions for side impacts. The expert from the Russian Federation confirmed that the Russian version of the text concerned would have to be aligned too. Referring to GRSG-112-26, the expert from OICA suggested introducing further improvements to the proposed amendments. GRSG noted some general support. The expert from Japan raised a study reservation. GRSG agreed to resume consideration of this subject at its next session in October 2017 on the basis of a revised official document jointly prepared by the experts from France and OICA.

Proposal to correct editorial errors, clarify the text, insert the proposal presented in document GRSG-111-13, and provide additional information to reflect provisions presented elsewhere in the text.

40. The expert from the Russian Federation, chairing the IWG on AECS, presented an updated proposal of draft UN Regulation on AECS (ECE/TRANS/WP.29/GRSG/2017/12). As Secretary of the IWG on AECS, the expert from OICA introduced GRSG-112-15 proposing some further editorial corrections to ECE/TRANS/WP.29/GRSG/2017/12. The expert from the Russian Federation introduced GRSG-112-27 clarifying mainly the scope and definitions of the draft UN Regulation.

The expert from OICA reiterated a concern about the economic burden for technical services and laboratories offering the more stringent tests due to the considerable costs of test equipment performing such acceleration/declaration of 65g.

41. Following a detailed consideration of ECE/TRANS/WP.29/GRSG/2017/12, GRSG adopted the new UN Regulation on AECS as reproduced in GRSG-112-42, subject to a final review at its October 2017 session of the official translations into the French and Russian languages. The GRSG Chair thanked again for the excellent work done by the IWG and for the acceptance by the Russian Federation to support the final proposal. The secretariat was requested to submit the adopted proposal to WP.29 and AC.1 as new draft UN Regulation on AECS for consideration at their November 2017 sessions, subject to a final review at the forthcoming GRSG session.

Proposal to require in the case where ogive protective covers are fitted to a cylinder that the covers be removed before conducting the impact damage (drop) test.

32. Reporting on some cases of structural failures of cylinders in his country, the expert from Italy proposed amendments to Annex 3A on the test requirements for the periodic requalification of cylinders (GRSG-112-28). The expert from Finland stated that these test requirements on periodical inspections of CNG/LNG vehicles in use were only recommendations to be taken into account during the type approval procedure of a new type of vehicle. GRSG noted that Contracting Parties were used to perform on their national level the periodical technical inspections in different ways. Referring to GRSG-112-32 presented under agenda item 7 (see para. 26 above), the expert from Germany introduced GRSG-112-33 proposing to also strengthen the requirements in UN Regulation No. 110 for the installation on vehicles of CNG-cylinders, LNG-tanks and their accessories as well as for their subsequent inspection of without the need of disassembling the containers.

33. GRSG noted general support on the proposals. The Chair invited all GRSG experts to send their comments, in due time, to the experts from Germany and Italy. GRSG agreed to resume consideration of this subject at its next session on the basis of official documents, prepared by Germany and Italy, taking into account the comments received.

Proposal to align UN R43 with GTR 6 and UN R125 with regard to the aiming positions of the driver’s eyes. This proposal corrects inconsistencies introduced during the transposition of GTR 6 into UN R43.

14. The expert from OICA introduced GRSG-112-29 to correct some inconsistencies in Annex 21, Table 2 and to align it with Global Technical Regulation No. 6 on safety glazing. GRSG welcomed the proposal and agreed to resume its consideration at the next session on the basis of an official document.

Proposal to correct the cross-reference in paragraph 6.3.3.2. where “the test shall satisfy the conditions laid down in paragraph 6.1.3. of this Regulation” should refer to paragraph 6.1.1.3.

17. Recalling the discussion in GRSG at its previous session, the expert from Germany introduced ECE/TRANS/WP.29/GRSG/2017/2 proposing to correct the provisions of paragraph 16.1.3.1. on the magnification factor. He also introduced GRSG-112-30 correcting a reference error in paragraph 6.3.3.2. The expert from France proposed to insert an editorial amendment to the communication form in Annex 4 (GRSG-112-08). GRSG adopted ECE/TRANS/WP.29/GRSG/2017/2 as amended below and requested the secretariat to submit it to WP.29 and AC.1 as draft Supplement 5 to the 04 series of amendment to UN Regulation No. 46 for consideration at their November 2017 sessions.

Paragraph 6.3.3.2., correct the reference to “paragraph 6.1.3.” to read “paragraph 6.1.1.3.”.
Annex 4, item 4., amend to read:
“4. Category of vehicle: (M1, M2, M3, N1, N2 ≤ 7.5 t, N2 > 7.5 t, N3, L) ²”

Proposal to require that components connecting the pressure relief device with the gaseous phase be made of metal.

25. Reporting on a severe incident which happened in 2014 (GRSG-112-31), the expert from Germany proposed a new series of amendments to UN Regulation No. 67 to enhance the specifications for the LPG multi-valve. The experts from Italy, the Netherlands and Poland confirmed such risks and endorsed the need to adopt such new provisions. The expert from Germany volunteered to submit an official document for consideration at the next GRSG sessions, including transitional provisions.

Proposal to establish a requirement for easy access to the LPG container installation in order to permit visual (periodical) inspection as a means to reduce the safety risks, such as refueling explosion, due to corrosion.

26. The expert from Germany proposed to also strengthen the requirements in UN Regulation No. 67 for the installation and inspection of LPG-containers and their accessories (GRSG-112-32). GRSG welcomed the proposal. The Chair invited all GRSG experts to send their comments, in due time, to the expert from Germany and proposed to resume consideration of this subject at the next session of GRSG on the basis of combined (see para. 25. above) proposal.

32. Reporting on some cases of structural failures of cylinders in his country, the expert from Italy proposed amendments to Annex 3A on the test requirements for the periodic requalification of cylinders (GRSG-112-28). The expert from Finland stated that these test requirements on periodical inspections of CNG/LNG vehicles in use were only recommendations to be taken into account during the type approval procedure of a new type of vehicle.

The expert from Finland stated that these test requirements on periodical inspections of CNG/LNG vehicles in use were only recommendations to be taken into account during the type approval procedure of a new type of vehicle. GRSG noted that Contracting Parties were used to perform on their national level the periodical technical inspections in different ways. Referring to GRSG-112-32 presented under agenda item 7 (see para. 26 above), the expert from Germany introduced GRSG-112-33 proposing to also strengthen the requirements in UN Regulation No. 110 for the installation on vehicles of CNG-cylinders, LNG-tanks and their accessories as well as for their subsequent inspection of without the need of disassembling the containers.

33. GRSG noted general support on the proposals. The Chair invited all GRSG experts to send their comments, in due time, to the experts from Germany and Italy. GRSG agreed to resume consideration of this subject at its next session on the basis of official documents, prepared by Germany and Italy, taking into account the comments received.

46. The expert from the Republic of Korea, chairing the IWG on PSG, reported on the work progress of the Group during its seventh meeting (GRSG-112-34). He added that the United States National Highway Traffic Safety Administration (US-NHTSA) was expected to complete the ongoing research and that the IWG had decided to wait for the updated research data and the final status report. GRSG welcomed the information and agreed to resume consideration of this subject at the next session.

Proposal as adopted (originally submitted as a proposal for Supplement 2 to the 07 series of amendments to UN Regulation No. 107) during the April 2017 GRSG session to address the concerns raised in document GRSG-111-35 through application of FprEN 16584-1:2015 and 2:2015, respectively referring to requirements for color contrast for signage and quality of audible information. The proposal also introduces provisions for passengers with limited mobility.

5. Recalling the discussion at the previous GRSG session on ECE/TRANS/WP.29/GRSG/2016/20, the expert from Switzerland presented GRSG-112-02-Rev.1 proposing to simplify the provisions of UN Regulation No. 107 by inserting references to parts 1 and 2 of the forthcoming updated European standards EN 16584:2015 on railway applications for persons with reduced mobility (GRSG-112-03 and GRSG-112-04). The expert from France preferred to leave these requirements out of the Regulation to avoid possible inconsistencies with existing national requirements. A number of experts preferred to keep some of the requirements proposed in GRSG-111-35 within the Regulation, but to improve the wording of the provisions concerned. Following the discussion, GRSG adopted ECE/TRANS/WP.29/GRSG/2016/20 as amended by GRSG-112-35 and agreed to submit it to WP.29 as a new 08 series of amendments to UN Regulation No. 107. Thus, the expert from OICA volunteered to prepare, in due time, a revised official document for consideration and final adoption at the next GRSG session, including the proposed transitional provisions (i.e. June 2020 for new types of vehicles and June 2022 for all existing types).

5. The expert from Germany recalled the purpose of ECE/TRANS/WP.29/GRSG/2016/20 to improve the accommodation and accessibility for passengers with reduced mobility. He added that GRSG had adopted the document in principle at its previous session as reproduced in GRSG-112-35 subject to the insertion of transitional provisions. Thus, the expert from OICA introduced GRSG-113-15-Rev.1. The expert from Sweden underlined the need to delete the amendments to Annex 8, paragraph 3.2.4. GRSG adopted ECE/TRANS/WP.29/GRSG/2016/20 as reproduced in Annex V to the session report (based on GRSG-113-15-Rev.2) and requested the secretariat to submit it to WP.29 and AC.1 as draft 08 series of amendments to UN Regulation No. 107 for consideration at their March 2018 sessions.

Presentation on the proposal for a new regulation on blind-spot information signalling for heavy vehicles.

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.

Presentation supporting GRSG/2017/10 to clarify the definitions of LPG container accessories to facilitate coordination between the separate, independent approvals required for the LPG container and for its accessories.

22. The expert from Poland gave a presentation (GRSG-112-37) justifying his proposal ECE/TRANS/WP.29/GRSG/2017/10 to clarify the provisions for type approved accessories fitted to LPG containers. The proposal received some support. The expert from AEGPL presented GRSG-112-20 proposing, as an alternative, the additional marking of the accessories with the number of type approval extension. Following a controversial discussion, the expert from Poland proposed to set up either a task force or a new informal working group on gaseous fuelled vehicles to work on the best solution. His proposal to establish an IWG did not receive full support. Finally, GRSG agreed to resume consideration of this subject at its next session in October 2017 on the basis of a new proposal jointly prepared by Poland and AEGPL. Thus, GRSG invited all interested experts to send them, in due time, their written comments.

The expert from ISO presented GRSG-112-38 justifying the need to harmonize the requirements on Compressed Natural Gas (CNG) and/or Liquefied Natural Gas (LNG) vehicles in UN Regulation No. 110 with those in the latest version of ISO 11439:2013 (as proposed in ECE/TRANS/WP.29/GRSG/2016/22). He recalled the comments received by GRSG experts during the last sessions (mainly on GRSG-111-02-Rev.1 and GRSG-112-05) and announced his intention to prepare, in due time, a revised official document for consideration at the next GRSG sessions, including transitional provisions.

Draft proposal under development by the IWVTA informal group to extract provisions from UN R116 into new regulations on immobilizers (see document GRSG-112-41) and vehicle alarm systems (see document GRSG-112-40) pursuant to the development of a new regulation on whole vehicle type approvals.

34. As GRSG ambassador on the International Whole Vehicle Type Approval (IWVTA), the expert from OICA presented the proposals on the splitting of the provisions of UN Regulation No. 116 into three separate Regulations (see para. 43 below), allowing the Contracting Parties to apply them on an optional or mandatory basis at their national/regional level. He briefly introduced (i) GRSG-112-39 containing the prescriptions for devices against unauthorized use as an amendment to UN Regulation No. 116, (ii) GRSG-112-40 as a new draft UN Regulation on vehicle alarm systems and (iii) GRSG-112-41 as a new draft UN Regulation on vehicle immobilizers. He added that the purpose of the exercise was only the splitting of the provisions without changes to the technical requirements. He sought the advice of GRSG on the need to insert transitional provisions for the amendments to UN Regulation No. 116 (as a Supplement or as a new series of amendments). The Chair invited all GRSG experts to send, in due time, their comments on the three documents to the GRSG ambassador.

35. GRSG acknowledged the work done and agreed to resume consideration of this subject at its next session in October 2017 on the basis of official documents to be submitted by the GRSG ambassador, including transitional provisions.

Proposal for a new UN Regulation on AECS as approved by the April 2017 GRSG session for submission to the World Forum for adoption. The doc version provides mark-up notations. The pdf is a clean version of the approved text.

40. The expert from the Russian Federation, chairing the IWG on AECS, presented an updated proposal of draft UN Regulation on AECS (ECE/TRANS/WP.29/GRSG/2017/12). As Secretary of the IWG on AECS, the expert from OICA introduced GRSG-112-15 proposing some further editorial corrections to ECE/TRANS/WP.29/GRSG/2017/12. The expert from the Russian Federation introduced GRSG-112-27 clarifying mainly the scope and definitions of the draft UN Regulation. She informed GRSG that from, a technical point of view, the corridor of sled pulse (60g) specified in ECE/TRANS/WP.29/GRSG/2017/12 was severe enough, but taking into account the importance and urgency for the adoption of the new UN Regulation by all Contracting Parties, the Russian Federation would support the more stringent corridor (65g) in line with the EU legislation. The expert from OICA reiterated a concern about the economic burden for technical services and laboratories offering the more stringent tests due to the considerable costs of test equipment performing such acceleration/declaration of 65g.

41. Following a detailed consideration of ECE/TRANS/WP.29/GRSG/2017/12, GRSG adopted the new UN Regulation on AECS as reproduced in GRSG-112-42, subject to a final review at its October 2017 session of the official translations into the French and Russian languages. The GRSG Chair thanked again for the excellent work done by the IWG and for the acceptance by the Russian Federation to support the final proposal. The secretariat was requested to submit the adopted proposal to WP.29 and AC.1 as new draft UN Regulation on AECS for consideration at their November 2017 sessions, subject to a final review at the forthcoming GRSG session.

39. WP.29 welcomed the submission by GRSG of a new draft UN Regulation on Accident Emergency Call Systems (AECS), including the alignment of the corridor of sled pulse (65g) with the EU legislation. The representative of the Russian Federation congratulated GRSG with such success and mentioned that this activity began at 2013 according Russian proposal and remained that analogical regulations are in force in Eurasian Economic Union from 2015 and they already had safe a lot of lives at road accidents.

37. The GRSG Chair reported on the results achieved during the 112th session of GRSG (for more details see the report of the session ECE/TRANS/WP.29/GRSG/91).

38. The GRSG Chair informed WP.29 about the submission of a Corrigendum to Global Technical Regulation No. 6 to clarify the scope and the technical rationale for consideration at the November 2017 sessions of WP.29 and AC.3.

39. WP.29 welcomed the submission by GRSG of a new draft UN Regulation on Accident Emergency Call Systems (AECS), including the alignment of the corridor of sled pulse (65g) with the EU legislation.

2. GRSG considered and adopted the agenda proposed for the 112th session (ECE/TRANS/WP.29/GRSG/2017/1 and Add.1).

2. GRSG considered and adopted the agenda proposed for the 112th session (ECE/TRANS/WP.29/GRSG/2017/1 and Add.1).

Proposal to correct paragraph 16.1.3.1. as follows: “The minimum and the average magnification factors of the CMS, in both horizontal and vertical directions shall not be lower than the minimum average magnification factors indicated below.” The latter reference to “minimum average” should be deleted since the subsequent text provides the required minimum and average magnification factors.

17. Recalling the discussion in GRSG at its previous session, the expert from Germany introduced ECE/TRANS/WP.29/GRSG/2017/2 proposing to correct the provisions of paragraph 16.1.3.1. on the magnification factor. He also introduced GRSG-112-30 correcting a reference error in paragraph 6.3.3.2. The expert from France proposed to insert an editorial amendment to the communication form in Annex 4 (GRSG-112-08). GRSG adopted ECE/TRANS/WP.29/GRSG/2017/2 as amended below and requested the secretariat to submit it to WP.29 and AC.1 as draft Supplement 5 to the 04 series of amendment to UN Regulation No. 46 for consideration at their November 2017 sessions.

Paragraph 6.3.3.2., correct the reference to “paragraph 6.1.3.” to read “paragraph 6.1.1.3.”.
Annex 4, item 4., amend to read:
“4. Category of vehicle: (M1, M2, M3, N1, N2 ≤ 7.5 t, N2 > 7.5 t, N3, L) ²”

Proposal to establish procedures for the approval of non-seamless double and single wall gas tubes provided they can withstand the applicable tests according to Annex 15.

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.

Proposal to correct the definition of “manual valve”, including deletion of the phrase “rigidly fixed to the cylinder or tank”. The definition of the manual valve as part of the accessories fitted to the container or tank (para. 4.16.) is different from the definition specified in paragraph 4.22. The proposed editorial change aims at clarifying the text of these definitions.

29. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2017/4 aimed at correcting an error in the definitions related to the manual valve. GRSG noted a number of comments and adopted ECE/TRANS/WP.29/GRSG/2017/4 as reproduced below. The secretariat was requested to submit it to WP.29 and AC.1 as draft Supplement 7 to the 01 series of amendment and as draft Supplement 1 to the 02 series of amendments to UN Regulation No. 110, for consideration at their November 2017 sessions.

Paragraph 4.22., amend to read:
“4.22. “Manual valve” means a valve which is operated manually."

Proposal to align UN R121 with the 07 series of amendments to UN Regulation No. 16:

1. the term “seat belt” is replaced by “safety belt”,
2. the symbol for safety belt, defined in item 21 of Table 1 in the Regulation, may be displayed in different colours to convey different meanings. Therefore, the existing footnote 18 has been added to item 21, and
3. this symbol may be replaced by different symbols for seats other than those of the front row. Therefore, a new footnote 22 is added to item 21.

This proposal also aligns UN R121 with ISO 2575 per ISO Resolution 664 allowing for use of the diesel engine glow plug symbol with non-diesel technologies that (also) assist engine starting at low temperatures. The current text of the Regulation focuses on diesel engine glow plugs that assist in starting the engine at low temperatures.

37. The expert from OICA presented GRSG-112-23 (superseding ECE/TRANS/WP.29/GRSG/2017/5) to align the provisions of UN Regulation No. 121 to those of the 07 series of amendments to UN Regulation No. 16 on safety belts. GRSG adopted the proposal as reproduced in Annex IV to the session report and requested the secretariat to submit it to WP.29 and AC.1 as part (see para. 36 above) of draft Supplement 2 to the 01 series of amendment to UN Regulation No. 121 for consideration at their November 2017 sessions.

38. The expert from the Russian Federation underlined the need to correct the Russian version of ECE/TRANS/WP.29/GRSG/2017/5 in line with the English text (GRSG-112-25). GRSG requested the secretariat to take into account the correction of the Russian translation when preparing the above mentioned official document.

Proposal to align the headform test with the deceleration measurement and the test of resistance to abrasion with ISO 15082:2016-11, including changes to the test details, correction of the headform calibration values, and the introduction of abrasion reference materials. The latter is combined with an abrasive-wheel qualification and a correction calculation (for plastic materials only).

11. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2017/6 to fully align (a) the provisions for the headform test with deceleration measurement and (b) the test of resistance to abrasion with those of the corresponding standard ISO 15082:2016-11. He added that the main amendments according to this standard were the addition or modification of important test details, the correction of the headform calibration values and the introduction of abrasion reference materials; the latter combined with an abrasive-wheel qualification and a correction calculation (for plastic materials only). GRSG welcomed the proposal and noted some minor editorial corrections. Following the discussion, GRSG adopted ECE/TRANS/WP.29/GRSG/2017/6 and requested the secretariat to submit it to WP.29 and AC.1 as draft Supplement 6 to the 01 series of amendments to UN Regulation No. 43 for consideration at their November 2017 sessions.

PSG informal group proposal to correct the scope of the GTR in accordance with Part A of the GTR, its UN R43 counterpart, and corresponding regional/national interpretations and to align the impact test procedure description with that of UN R43 and ISO 3537.

45. GRSG considered ECE/TRANS/WP.29/GRSG/2017/7 (submitted by the IWG on Panoramic Sunroof Glazing (PSG)) to clarify the scope and the technical rationale of UN Global Technical Regulation No. 6. GRSG recommended the document for their establishment in the global registry. The secretariat was requested to submit it to WP.29 and to the Executive Committee AC.3 of the 1998 Agreement (AC.3) as Corrigendum 2 to Global Technical Regulation No. 6 for consideration at their November 2017 sessions.

Proposal to amend Figure 2a of Annex 21 to better reflect the meaning of paragraph 2.4.2.2. of Annex 21, mainly to clarify the lateral limits of any opaque obscuration in this area.

12. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2017/8, proposing to clarify in Figure 2a of Annex 21 the lateral limits of any opaque obscuration. GRSG noted general support and adopted the proposal. The secretariat was requested to submit it to WP.29 and AC.1 as part (see para. 11 above) of draft Supplement 6 to the 01 series of amendments to UN Regulation No. 43 for consideration at their November 2017 sessions.

Proposal to introduce provisions for cargo-compartment refrigeration systems connected to the compressed natural gas (CNG) and/or liquefied natural gas (LNG) system(s).

30. The expert from France introduced ECE/TRANS/WP.29/GRSG/2017/9 incorporating provisions concerning refrigeration systems for cooling the cargo compartment which were connected to the CNG and/or LNG system. GRSG noted general support. GRSG adopted document ECE/TRANS/WP.29/GRSG/2017/9 as amended below. The secretariat was requested to submit it to WP.29 and AC.1 as part (see para. 29 above) of draft Supplement 1 to the 02 series of amendments to UN Regulation No. 110 for consideration at their November 2017 sessions.

In paragraph 18.5.1.3., replace “GNC/GNL” to read “CNG/LNG” (twice).

Proposal to clarify the definitions of LPG container accessories to facilitate coordination between the separate, independent approvals required for the LPG container and for its accessories. The proposal aims to ensure proper coordination between container approvals (which involve testing with accessories attached) and accessory approvals (which may be subsequent to the original container approval and therefore, relevant to its validity).

22. The expert from Poland gave a presentation (GRSG-112-37) justifying his proposal ECE/TRANS/WP.29/GRSG/2017/10 to clarify the provisions for type approved accessories fitted to LPG containers. The proposal received some support. The expert from AEGPL presented GRSG-112-20 proposing, as an alternative, the additional marking of the accessories with the number of type approval extension. Following a controversial discussion, the expert from Poland proposed to set up either a task force or a new informal working group on gaseous fuelled vehicles to work on the best solution. His proposal to establish an IWG did not receive full support. Finally, GRSG agreed to resume consideration of this subject at its next session in October 2017 on the basis of a new proposal jointly prepared by Poland and AEGPL. Thus, GRSG invited all interested experts to send them, in due time, their written comments.

Proposal to establish requirements for Blind Spot Information Systems (BSIS) intended to be fitted in heavy goods vehicles to protect vulnerable road users. This proposal is based on GRSG-109-19 and explained in presentations GRSG-110-18-Rev.1 and GRSG-111-24.

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.

27. The expert from Germany reported that ECE/TRANS/WP.29/GRSG/2017/11 was still under consideration by the IWG on VRU-Proxi. He announced the intention of the IWG to further review the proposal at its forthcoming meetings and to submit it to GRSG for consideration at the next session in April 2018. GRSG agreed to keep ECE/TRANS/WP.29/GRSG/2017/11 on the agenda as a reference document, awaiting submission by the IWG of the revised proposal.

20. The expert from Germany recalled the purpose of ECE/TRANS/WP.29/GRSG/2017/11 and reported on the outcome of the IWG on VRU-Proxi (GRSG-114-21). The IWG had recommended enlarging the scope of the new UN Regulation on vehicles of categories M2 and M3. The expert from OICA stated that this amendment was premature and that accident data did not yet justify a broader scope to vehicles of categories M2 and M3. GRSG noted that, for some regions, the need was based on general safety provisions.

21. The expert from the United Kingdom supported the proposal in general, but pointed out that drivers could possibly disconnect such warning systems. He underlined the need for further research on the effectiveness of such information systems, especially Human-Machine Interface (HMI).

22. The expert from Germany stated his intention to review the proposal and to submit, in due time, a revised proposal for consideration by GRSG at its October 2018 session.

Updated proposal from the AECS informal working group for a new UN Regulation on accident emergency call systems and devices.

40. The expert from the Russian Federation, chairing the IWG on AECS, presented an updated proposal of draft UN Regulation on AECS (ECE/TRANS/WP.29/GRSG/2017/12). As Secretary of the IWG on AECS, the expert from OICA introduced GRSG-112-15 proposing some further editorial corrections to ECE/TRANS/WP.29/GRSG/2017/12. The expert from the Russian Federation introduced GRSG-112-27 clarifying mainly the scope and definitions of the draft UN Regulation. She informed GRSG that from, a technical point of view, the corridor of sled pulse (60g) specified in ECE/TRANS/WP.29/GRSG/2017/12 was severe enough, but taking into account the importance and urgency for the adoption of the new UN Regulation by all Contracting Parties, the Russian Federation would support the more stringent corridor (65g) in line with the EU legislation.

The expert from the Russian Federation, chairing the IWG on AECS, recalled the detailed consideration of GRSG at its previous session of the new UN Regulation on AECS on the basis of ECE/TRANS/WP.29/GRSG/2017/12. He informed GRSG that the IWG had again reviewed the proposal to remove some editorial inconsistencies. He added that the latter ones have been taken into account in the official document ECE/TRANS/WP.29/2017/132 which was submitted to WP.29 and AC.1 for consideration at their November 2017 sessions.
