6. The Chair presented GRPE-79-04-Rev.2 detailing priority topics for GRPE activities, as prepared by the Chair and the secretariat. The Chair highlighted the need to develop this GRPE priorities document to fulfil the political demand as stipulated in the Inland Transport Committee (ITC) Strategy adopted during the last ITC session in February 2019. WP.29 also expressed their wish to identify work priorities in the GRs to potentially allocate adequate resources to fulfil the objectives set by each GR. He also underlined that the priorities should be aligned with the SDGs, developed under the 2030 Agenda.

7. GRPE supported the proposal and found this approach highly relevant in the rapidly evolving context and digitalization of vehicles. Some Contracting Parties (CPs) wanted more clarity on the potential future topics under the UN vehicle agreements (1958, 1997 or 1998 Agreement) will be developed under. The secretariat highlighted this document is aimed at being a bottom-up from GRPE stakeholders that would then be discussed and coordinated during AC.2 sessions of WP.29.

8. GRPE agreed to support the Chair to request IWG on Periodic Technical Inspection (PTI) (WP.29) to come and present on on-going and longer-term activities at forthcoming sessions of GRPE, to foster closer collaboration on lifetime compliance.

9. GRPE agreed to rename agenda item 13 into “Priority topics for GRPE activities” where this issue will be covered regularly in future GRPE sessions (see para. 66).

10. GRPE edited GRPE-79-04-Rev.2 during the session and based on comments received from CPs not attending. GRPE agreed to submit the amended document to the next session of GRPE in January 2020 as an informal document (GRPE-80-04). The Chair proposed to present this document during the March 2020 session of WP.29 once GRPE had agreed on the content of the document.

3. Light vehicles
3. (a) UN Regulations Nos. 68 (Measurement of the maximum speed, including electric vehicles), 83 (Emissions of M1 and N1 vehicles), 101 (CO2 emissions/fuel consumption) and 103 (Replacement pollution control devices)

11. The representative from CITA introduced GRPE-79-06 on the highlights of the CITA annual congress held in Republic of Korea in April 2019. He summarized the latest updates on emissions measurements during PTI tests. The Chair highlighted the importance of the topic and recalled it has been included in the draft priority list of GRPE (see para. 6).

12. The representative from Spain referred to the measurement of particulate number (PN) and asked whether a mature technology to measure PN during PTI tests was available on the market. The representative from CITA explained that the technology was mature and that some countries were about to implement PN measurements during PTI tests in the coming years, in the 2020/2021 time horizon. The representative from Netherlands confirmed PN tests are expected in 2021. He also highlighted the importance of in-use emission monitoring in the rapid technology changes the vehicle industry is facing, with digitalization, over-the-air updates and self-learning features that need to be considered.

GRPE-79-06 | Summary of the CITA international conference, Seoul, 2-4 April 2019

13. The representative from CITA introduced GRPE-79-05 proposing amendments to the 06 and 07 series of amendments to UN Regulation No. 83. The representative from EC wondered if the proposed new paragraph 5.1.9. would not be more appropriate in UN Regulation No. 49 where there is evidence of Selective Catalytic Reduction (SCR) tampering of heavy-duty vehicle was better documented. The representative from CITA reckoned the issue with SCR tampering in heavy-duty applications was existing and documented and clarified the intention to amend UN Regulation No. 83 was to anticipate expected future issues for light-duty vehicles.

14. The representative from OICA stated the proposed amendment implied physical changes to existing vehicles for infrequent road worthiness tests. He added that such proposal does not make tampering more difficult. He said a better way would be to address the offer of tampering devices, for example following the initiative from Austria legally prohibiting the sale and advertisement of tampering devices. He did not support the proposal and encouraged closer collaboration with CITA to improve the situation of road-side and inspection tests. The representative from CITA agreed the proposal needed to be strengthened, and this proposal was a first step. He said that authorities performing road worthiness tests needed to be able to measure emissions to characterize tampering, which was not often the case today, partly because of lack of access to software and sensors signals of the vehicles.

15. The Chair highlighted undertaking the issue of tampering was an ample strategy needing diverse approaches to it, through vehicle design, PTI, roadside inspection, market availability, etc. and invited CITA to table a working document for the next session of GRPE in January 2020, in close collaboration with EC, OICA and other interested stakeholders.

16. The expert from OICA introduced GRPE-79-10 requiring clarification on the consolidation of ECE/TRANS/GRPE/2017/2 into UN Regulation No. 83. The representative from EC suggested that the issue identified could originate from how the document was drafted. The Chair accepted the request for clarification was valid and acknowledged the request for guidance from GRPE on consolidation interpretation when needed. The representative from the Russian Federation, as submitter of ECE/TRANS/GRPE/2017/2, confirmed that the new text is an addition to the existing paragraph, not a substitution. The Chair confirmed that paragraph 1.1. consolidated with Supplement 10 and 5 to the 06 and 07 series of amendments to UN Regulation No. 83 should read:

“1.1.

This Regulation shall apply to vehicles of categories M1, M2, N1 and N2 with a reference mass not exceeding 2,610 kg.

At the manufacturer’s request, type approval granted under this Regulation may be extended from vehicles mentioned above to M1, M2, N1 and N2 vehicles with a reference mass not exceeding 2,840 kg and which meet the conditions laid down in this Regulation.

At the manufacturer’s request, type approval granted under this Regulation may be extended from vehicles mentioned above to special purpose vehicles of categories M1, M2, N1 and N2 regardless of their reference mass. The manufacturer shall demonstrate to the Type Approval Authority which granted the type approval that the vehicle in question is a special purpose vehicle.”

GRPE-79-10 | UN R83: Request for interpretation of Supplement 6 to the 07 series of amendments (GRPE/2017/2) OICA request for clarification on the interpretation of Supplement 6 to the 07 series of amendments to UN R83 which enables the use of compliance assessments of vehicles with a reference mass less than 2,610 kg for the purposes of extending the type approval to special purpose vehicles (including armoured ones) having a reference mass exceeding 2,840 kg.
GRPE/2017/2 | Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83 Proposal to allow the use of compliance assessments of vehicles with a reference mass less than 2,610 kg in extending the type approval to special purpose vehicles (including armoured ones) having a reference mass exceeding 2,840 kg. This proposal would align UN R83 with provisions of European Directive 2007/46/EC.

17. The expert from OICA updated GRPE on the status of the work related to propose an amendment to UN Regulation No. 101 (GRPE-79-11) to accept the tests currently performed in the European Union in the interest of correlation between NEDC and WLTP outside of the European Union where such correlation does not exist. The representative of Australia described the measure taken in the country to accept approvals based on WLTP and still rely on NEDC-based values for fiscal and labelling purposes.

GRPE-79-11 | UN R101: Updated information on OICA proposal Update on the status of work regarding the transition from NEDC to WLTP, particularly pending the transposition of GTR 15 into one or more UN Regulations under the 1958 Agreement.

18. The expert from OICA introduced GRPE-79-15, GRPE-79-16 and GRPE-79-17 proposing modifications to the 07 series of amendments to UN Regulation No. 83 on On-Board Diagnosis (OBD). The representative from Netherlands, France and EC required more time to analyse the proposals and to consult internally with the appropriate experts on OBD. The representative from EC requested a more thorough assessment and more detailed specifications of the needs and requirements to amend the regulatory text. The Chair acknowledged that the specific expertise on OBD from CPs was in most cases not present in the room and proposed OICA to further develop the proposals and submit as working documents for the next session of GRPE in January 2020.

GRPE-79-15 | UN R83: Proposal for Amendment to the 07 series - Definition of Permanent default Proposal to clarify "permanent default" and "limp-home mode" in UN R83.
GRPE-79-16 | UN R83: Proposal for Amendment to the 07 series - Definitions to erase fault codes Proposal to amend current definitions to allow fault code erasing in cold regions (< -7°C) and high altitude (> 2440m), harmonizing the definitions with those used in China and the United States.
GRPE-79-17 | UN R83: Proposal for Amendment to the 07 series - Introduction of Special denominator Proposal to allow for the use of use special denominator conditions for certain components or systems. The current definitions of the specific denominators are based on engine/aftertreatment system combinations designed as one TWC for gasoline vehicles and DOC, DPF and SCR respectively NSC for diesel engines. Upcoming emission requirements will bring up additional aftertreatment components like Gasoline Particulate Filters (GPF) or new designs with more than one SCR catalyst. Such new systems or catalyst combinations might require specific conditions to enable the monitoring, especially when their purpose is designed for such conditions.
3. (b) UN Global Technical Regulations Nos. 15 (Worldwide harmonized Light vehicles Test Procedures (WLTP)) and 19 (Evaporative emission test procedure for the Worldwide harmonized Light vehicle Test Procedure (WLTP EVAP)).

19. The Chair of IWG on WLTP introduced GRPE-79-08-Rev.1 updating GRPE on the latest activities of IWG on WLTP. He requested an extension until June 2020 for the activities of the group, as he recalled GRPE the current Terms of Reference (ToRs) of IWG on WLTP had an expiration date in December 2019. The representative from Canada asked about the plans of IWG on WLTP after Jun 2020. The Chair of IWG on WLTP stated the future will depend on the content of the work which remained to be defined at the time. The Chair of GRPE highlighted it would be important to hold the discussions with all other IWGs. GRPE noted the request for a meeting room for one and a half day during the GRPE week in January 2020.

20. The representative from EC indicated that the work item on road loads covered in the status report was discussed and some CPs requested it, but the item was finally not prioritized. She agreed with the extension of the ToRs for IWG on WLTP for six months and requested that longer-term work items should be considered in conjunction with the broader work priorities for GRPE (as introduced in paras. 6 to 10). The representative of Switzerland was also in agreement with the six-month prolongation and to further align with the GRPE priorities.

21. GRPE agreed to prolong the work of IWG on WLTP until June 2020, as reflected in Annex III.

22. The representative from EC introduced GRPE-79-19 on the latest activities of the Transposition Task Force aimed at drafting a UN Regulation from UN GTRs Nos. 15 and 19. The representative from OICA requested about the possibility to include specific provisions for CPs only needing national application for a national context to not have to wait for the most stringent Level 1 subject to mutual recognition to enter into force to fully benefit from the latest evolution of the legal text. Currently an additional six-month period is envisaged so that the regional levels are not subject to mutual recognition. The representative from OICA also appealed to certification or Type Approval Authorities whether the proposed approach to identify the stringency level by its series of amendment number was enough to identify the harmonization level or that an indication of the level of harmonization would also be needed in the approval number.

3. (c) Worldwide harmonized Real Driving Emissions test procedure.

24. The representative from EC introduced GRPE-79-20-Rev.1 detailing the latest activities from IWG on RDE. She added that, in parallel with the development of the UN GTR on RDE, a new UN Regulation on RDE would be developed, based on European Union legislation. GRPE agreed to the development of a new UN Regulation on RDE. The representative from European Union confirmed that both UN GTR and UN Regulation will be closely looked after to avoid any discrepancies between the two texts.

25. GRPE noted the request for a meeting room for a day during the GRPE week in January 2020.

30. The expert from Italy presented ECE/TRANS/WP.29/GRPE/2019/10 which established the conditions to consider direct and indirect injection vehicles as being part of the same approval family. The representative from Netherlands requested some clarifications to the text to make sure the Particulate Number (PN) limit was valid. The representative from Italy declared the proposal has no impact on gasoline operations and a proposed slight amendment to the text, as reproduced in Annex IV. The representatives from Netherlands, France and EC agreed the proposed new text clarified the proposal.

31. The representative from Liquid Gas Europe agreed with the proposed improvement and supported the proposal.

32. GRPE endorsed the proposal and requested the secretariat to submit Annex IV of the session report to WP.29 and AC.1 for consideration and vote at their November 2019 sessions as draft Supplement 9 to UN Regulation No. 115.

GRPE/2019/10 | UN R115: Proposal for a new Supplement This proposal amends UN Regulation No. 115 to list conditions, especially with regard to retrofit systems, to be met by indirect and direct injection vehicles to be considered as belonging to the same vehicle family. Gasoline direct injection vehicles which operate in indirect gas injection mode should be listed in the same family as indirect gasoline injection vehicles, as the applied gas injection technology is the same and provided that at least one such vehicle is tested as parent vehicle according to the requirements of this Regulation.

33. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2019/11 and GRPE-79-27-Rev.1 that amended the footnote 9 in table 1 of Annex 5 to introduce an alternative for the measurement of power of charge-air-cooled engines. The representative from United Kingdom of Great Britain and Northern Ireland required clarifications on considerations about the test temperature and potential concerns about tests being done at extreme temperatures. Amendments were provided in GRPE-79-27-Rev.1. GRPE supported the new proposal in GRPE-79-27-Rev.1 as reproduced in Annex V of the session report.

34. GRPE endorsed the proposal and requested the secretariat to submit Annex V of the report to WP.29 and the AC.1 for consideration and vote at their November 2019 sessions as draft Supplement 10 to UN Regulation No. 85.

GRPE-79-27/Rev.1 | UN R85: Amendments document GRPE/2019/11 Proposal to allow an alternative test method to “set the charge air cooler outlet temperature during bench test to temperature which was observed by vehicle test and corrected to the reference temperature specified in paragraph 5.2.1.” of Annex 5. This alternative method is well recognized in SAE J1349.
GRPE/2019/11 | UN R85: Proposal for a new Supplement Proposal to allow an alternative test method to “set the charge air cooler outlet temperature during bench test to temperature which was observed by vehicle test and corrected to the reference temperature specified in paragraph 5.2.1.” of Annex 5. This alternative method is well recognized in SAE J1349.
6. Agricultural and forestry tractors, non-road mobile machinery

36. GRPE did not receive any new proposal to amend UN GTR No. 11.

7. Particle Measurement Programme (PMP)

37. The representative from the Russian Federation introduced GRPE-79-07 raising awareness of non-exhaust particulate emissions from brake, tyre and road abrasion. The Chair highlighted the topic was in the agenda of IWG on PMP, highlighting the relevance of the topic. He also mentioned GRBP was considering a proposal from Netherlands on road surface labelling that included traffic noise reduction, wet skid resistance, rolling resistance and lifespan (ECE/TRANS/WP.29/GRB/2019/2).

GRB/2019/2 | Revised proposal for a draft Resolution on road surface labelling

38. The Chair of IWG on Particle Measurement Programme (PMP) presented a status report on activities on exhaust and non-exhaust particle emissions (GRPE-79-13).

39. The representative from India enquired about any correlation between existing evaporation tubes and strippers for sub-23 nm particulate emission measurements. The Chair of IWG on PMP answered evaporation was working for diesel engines, and that for spark ignition engines (e.g. 2-stroke L-category vehicles), some artefacts were measured. IWG on PMP was considering adoption of two approaches for the future. The representative from India asked further explanations about the dispersion found in the round robin tests. The Chair of IWG on PMP explained two Condensation Particle Counters (CPCs) were connected to the same exhaust line, one to measure 23nm particulates, one to measure 10nm particulates. He highlighted the location of the sampling points are of high importance and could explain part of the dispersion found. He emphasized that the hot start variability was higher as absolute values were lower than for cold starts. The representative from India finally asked whether the dispersion was fit for post Euro 6 measurements. The Chair of IWG on PMP answered that only one CPC would be prescribed in the future legislation, ensuring more consistent measurement and easier location of the sampling point in the exhaust line.

40. The Chair requested about the expected timeline to deliver on a procedure for sub-23 nm particulate measurement. The Chair of IWG on PMP confirmed they are expecting a working document for the GRPE session of June 2020.

41. The representative of the United States of America confirmed the findings on non-exhaust particulate in the US were consistent with IWG on PMP and the results shown by the representative of the Russian Federation in GRPE-79-07. He explained that the characteristics of tyres are changing to improve safety and rolling resistance and encouraged GRPE to carefully consider the impact of such tyre modifications on the wear of tyres and associated particulate emissions. He proposed to potentially make a presentation at the next GRPE session in January 2020 about the on-going activities in the United States of America on the matter.

42. The Chair of IWG on PMP introduced the revised ToRs of IWG on PMP (GRPE-79-14) seeking to extend the activities of IWG on PMP until June 2021. The Chair of IWG on WLTP asked whether IWG on WLTP should anticipate some work loads to adapt UN GTR No. 15 to sub-23nm requirements. The Chair of IWG on PMP did not expect in-depth modifications to UN GTR No.15 and would be happy to further work with IWG on WLTP to better coordinate the activities.

43. The representative from OICA requested further considerations on transitional provisions when the new method to measure sub-23nm particulates had been finalized. The Chair agreed such considerations were important and will be undertaken when the new procedure became available and ready to be included into legal texts.

GRPE-79-13 | Status report of the PMP informal group

44. The representative from EUROMOT requested clarifications about a potential update to UN Regulation No. 96 as a new series of amendments had just been released. The Chair confirmed UN Regulation No. 96 should also be considered for inclusion of sub-23nm particulate emission measurement. The representative from EUROMOT highlighted that the upcoming sub-23 nm measurement procedure was likely to be implemented for light and heavy-duty vehicles as part of new emission limits package, whereas in the case of Non-Road Mobile Machinery (NRMM), a new package had recently been adopted. The Chair of IWG on PMP confirmed the work on sub-23nm was focusing on on-road applications, and no development work was on-going for NRMM, for which a validation could be performed if needed. The Chair proposed to investigate further to assess the differences between on-road and off-road applications when the procedure would be available.

45. GRPE supported the extension of the mandate of IWG on PMP until June 2021 as reflected in Annex III of the session report.

46. GRPE acknowledged the progress made by IWG on PMP and noted the request for a meeting room for a half a day during the GRPE week in January 2020.
