Pursuant to GRPE discussions, the proposal adds the following paragraph to the amendment:
“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.”

7. The expert from the Russian Federation presented ECE/TRANS/WP.29/GRPE/2017/2 on amendments to the scope of Regulation No. 83. He explained that the proposal was aimed at allowing extensions of type approvals granted under Regulation No. 83 to special purpose vehicles.

8. The experts from CLEPA and OICA expressed some concerns on the limitation of 2,610 kg reference mass introduced by the definition of special purpose vehicle in ECE/TRANS/WP.29/GRPE/2017/2. The expert from Hungary suggested the use of existing definitions in the Consolidated Resolution on the Construction of Vehicles (R.E.3). Following the discussion, the experts from Hungary and the Russian Federation presented GRPE-74-22 to amend ECE/TRANS/WP.29/GRPE/2017/2 by deleting the definitions of special purpose vehicle and armoured vehicle and referring to R.E.3 instead.

9. GRPE adopted ECE/TRANS/WP.29/GRPE/2017/2 amended by GRPE-74-22 as reproduced in Annex IV and requested the secretariat to submit it to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2017 sessions as draft Supplement 10 to the 06 series of amendments and draft Supplement 6 to the 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.

7. The expert from the Russian Federation presented ECE/TRANS/WP.29/GRPE/2017/2 on amendments to the scope of Regulation No. 83. He explained that the proposal was aimed at allowing extensions of type approvals granted under Regulation No. 83 to special purpose vehicles.

9. GRPE adopted ECE/TRANS/WP.29/GRPE/2017/2 amended by GRPE-74-22 as reproduced in Annex IV and requested the secretariat to submit it to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2017 sessions as draft Supplement 10 to the 06 series of amendments and draft Supplement 6 to the 07 series of amendments to Regulation No. 83.

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:

Proposal to adapt the 06 and 07 series of amendments to Regulation No. 83 to Selective Catalytic Reduction (SCR) warning and inducement systems to current vehicles, emissions requirements and reagent infrastructure. In light of further vehicle weight reduction for CO2 optimization and the resultant vehicle packaging challenges, diesel cars will likely have smaller AdBlue® reagent tanks. For passenger cars, the warning indicator to refill AdBlue® has to be activated at 2,400 km of remaining reagent range which could result in very frequent refills of smaller reagent tanks. This proposal would allow for reagent refill inducement warnings as a percentage of tank capacity. For heavy-duty vehicles, the warning has to be activated at least at a reagent level of 10 per cent of total reagent tank volume. The inducement system has to be activated at least at 2.5 per cent of reagent level.

10. The expert from OICA withdrew ECE/TRANS/WP.29/GRPE/2017/5 on amendments to Regulation No. 83 to adapt the provisions on selective catalytic reduction warning and inducement systems to current vehicles, emissions requirements and reagent infrastructure. He mentioned that this is an urgent topic and that differences between European legislation and UN Regulations should be minimized. He announced his intention to address this topic first at the European level, and he invited all stakeholders to contribute to the discussion since the beginning.

The subject documents would permit Contracting Parties applying UN R83 and/or UN R101 and which have transposed GTR No. 15 (WLTP) into their local legislation to refuse to accept type approvals granted under the UN R83 and/or UN R101 as a compliance alternative to their national/regional legislation (i.e., aligned with GTR No. 15). OICA proposes to clarify the intent by deleting allusions to the measure as a form of derogation, to replace the phrase “may no longer accept” with “may refuse”, and to introduce a sunset clause to noting that the measure is intended as a stop-gap until such time as GTR No. 15 has been transposed into the corpus of UN Regulations.

11. The Secretary of GRPE presented ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44 on transitional provisions to be introduced in Regulations Nos. 83 and 101 as an interim solution while the Worldwide harmonized Light vehicles Test Procedure (WLTP) is transposed into the 1958 Agreement. He explained that these documents were prepared by the Secretariat as agreed by WP.29 at its June 2016 session. Following the request of WP.29 and taking into account the urgency of the topic, he explained that the three proposals were already submitted to WP.29 and AC.1 for consideration and vote at their March 2017 sessions, but subject to the endorsement of GRPE at this session.

12. The expert from OICA presented GRPE-74-16 on some modifications to the wording of ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44. The expert from EC stated that he was not in the position to accept the changes introduced by GRPE-74-16.

13. Following the discussion, GRPE endorsed ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44 to be further considered by WP.29 and AC.1 at their March 2017 sessions.

Proposal, subject to endorsement by the GRPE during its January 2017 session, to permit Contracting Parties applying UN R83 and GTR No. 15 (WLTP) to refuse type approvals granted under UN R83 as an alternative to compliance with their national/regional legislation from the date of entry into force of Supplement 9 to the 06 series of amendments to UN R83.

11. The Secretary of GRPE presented ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44 on transitional provisions to be introduced in Regulations Nos. 83 and 101 as an interim solution while the Worldwide harmonized Light vehicles Test Procedure (WLTP) is transposed into the 1958 Agreement. He explained that these documents were prepared by the Secretariat as agreed by WP.29 at its June 2016 session. Following the request of WP.29 and taking into account the urgency of the topic, he explained that the three proposals were already submitted to WP.29 and AC.1 for consideration and vote at their March 2017 sessions, but subject to the endorsement of GRPE at this session.

12. The expert from OICA presented GRPE-74-16 on some modifications to the wording of ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44. The expert from EC stated that he was not in the position to accept the changes introduced by GRPE-74-16.

13. Following the discussion, GRPE endorsed ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44 to be further considered by WP.29 and AC.1 at their March 2017 sessions.

75. The representative of the Netherlands, Chair of GRPE presented ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44 on the introduction of transitional provisions in Regulations Nos. 83 and 101. He mentioned that GRPE endorsed the three documents at its January 2017 session. He recalled that the documents were prepared by the Secretariat at the request of WP.29 at its June and November 2016 sessions. He explained that the transitional provisions were an interim solution until a UN Regulation implementing WLTP was in place. He mentioned that the transitional provisions would prevent Contracting Parties that implement gtr No. 15 (WLTP) at an earlier stage to cease applying Regulations Nos. 83 and 101.

76. The representative of the Russian Federation introduced WP.29-171-27. He mentioned his understanding about the need of the proposal in ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44, but he expressed his concerns on whether the content was fully in line with the 1958 Agreement. He explained the need of the Russian Federation to consult with partners from Euroasian Economic Union before adopting these amendments.

77. The representative of the Euroasian Economic Commission (EEC) stated that EEC harmonizes legislation on transport in line with UN Regulations. He expressed his concerns on the tabled proposals (ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44) and he explained that previous consultation within EEC members before adoption of the proposals would be appreciated.

78. The Vice-Chair of WP.29 underlined that the introduction of such transitional provisions into Regulations Nos. 83 and 101 may lead to confusing situations and certain abuses.

79. The representative of OICA noted that the transitional provisions were expected to maintain the possibility to grant approvals according to UN R83.07 (or earlier version) and UN R101 even by Contracting Parties that would refuse those approvals after the introduction of mandatory application of emission legislation based on WLTP.

80. In this sense, he remarked that the derogation mentioned in the proposed transitional provisions in fact was referring to the obligation to refuse vehicles approved to the 07 series of amendments o Regulation No. 83 (or its 06 series of amendments) or Regulation No. 101 on the territory of the Contracting Party that already had implemented WLTP, and would not derogate to the possibility to grant approval according to the above UN Regulations for export to other countries. WP.29 confirmed this interpretation.

81. The World Forum considered the draft amendments under items 4.10.1 and 4.10.3 and recommended their submission to AC.1 for voting.

Proposal, subject to endorsement by the GRPE during its January 2017 session, to permit Contracting Parties applying UN R83 and GTR No. 15 (WLTP) to refuse type approvals granted under UN R83 as an alternative to compliance with their national/regional legislation from the date of entry into force of Supplement 5 to the 07 series of amendments to UN R83.

11. The Secretary of GRPE presented ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44 on transitional provisions to be introduced in Regulations Nos. 83 and 101 as an interim solution while the Worldwide harmonized Light vehicles Test Procedure (WLTP) is transposed into the 1958 Agreement.

17. The expert from EC presented ECE/TRANS/WP.29/GRPE/2017/3 on a draft new GTR on evaporative emission test procedure for WLTP (WLTP EVAP). He clarified that the current proposal focuses on the evaporative emissions that can occur during parking events, so running losses and refuelling emissions are out of the scope for the time being. He explained that the test procedure for sealed fuel tank systems will be introduced at a later stage. He introduced the technical report on the development of the draft new GTR (GRPE-74-04).

19. GRPE adopted ECE/TRANS/WP.29/GRPE/2017/3 and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2017 sessions as a new draft GTR on evaporative emission test procedure for WLTP (WLTP EVAP). GRPE also adopted the technical report (GRPE-74-04) as reproduced in Addendum 2 to this report and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2017 sessions.

Text prepared by the Evaporative emissions Task Force of the WLTP informal working group in line with Phase 2 of its mandate (ECE/TRANS/WP.29/AC.3/44). The WLTP referred to a first draft of this proposal (GRPE-73-12) at the seventy-third session of GRPE (see report ECE/TRANS/WP.29/GRPE/73, para. 12).

17. The expert from EC presented ECE/TRANS/WP.29/GRPE/2017/3 on a draft new GTR on evaporative emission test procedure for WLTP (WLTP EVAP). He clarified that the current proposal focuses on the evaporative emissions that can occur during parking events, so running losses and refuelling emissions are out of the scope for the time being. He explained that the test procedure for sealed fuel tank systems will be introduced at a later stage. He introduced the technical report on the development of the draft new GTR (GRPE-74-04).

Pursuant to the development of a GTR on evaporative emissions under the WLTP informal group, ETRMA presents its views on the draft procedure in order to clarify the role of tyres.

18. The expert from ETRMA presented GRPE-74-10 to highlight that emissions from tyres should be excluded from the test procedure in the draft new GTR on WLTP EVAP. He explained that tyres should be removed at the stage of vehicle preparation, since they are not part of the fuel storing system and they may add some uncertainty to the test.

30. The expert from EC presented GRPE-72-18 on the transposition of GTR No. 15 into the legislation of the European Union. He informed GRPE about the progress made on the development of a new European Regulation, which was expected to replace the New European Driving Cycle (NEDC) in 2017 and which had a specific annex based on GTR No. 15 adapted to the European requirements.

31. The expert from EC continued his presentation (GRPE-72-18) on the transposition of GTR No. 15 into new Regulations annexed to the 1958 Agreement. He underlined the agreement of WP.29 at its November 2015 session on developing a new Regulation on WLTP with one top level (highest stringency) and other different levels of stringency below that top level. He recalled that the top level (Level 2) would correspond to the most stringent combination of regional requirements, whereas the levels below (Level 1a, Level 1b, etc.) would correspond to a specific national or regional legislation in terms of emission limits as well as region-specific technical and administrative requirements. He showed a possible structure of a new Regulation on WLTP and he highlighted the different parts (e.g. Annexes on approval marks and the communication form) that should enable distinction between the different levels. He introduced a possible structure of a second new Regulation that would complement the Regulation on WLTP (type 1 test only) by referring to the relevant parts of Regulation No. 83 on other test types. As the technical sponsor for these activities, he sought the advice of GRPE on the best way to move forward.

32. The expert from OICA underlined the need of Level 2 to be used for the Universal International Whole Vehicle Type Approval (U-IWVTA) as it would be the only level subjected to mutual recognition between all Contracting Parties to the 1958 Agreement applying the Regulation. He highlighted the complexity of defining Level 2 because of the different factors needed to be taken into account when defining the highest stringency (e.g. emissions limits, test, fuel, vehicle size and technology).

33. The Chair of GRPE mentioned that including Level 2 directly in the original version of the new Regulation on WLTP together with the levels below (Level 1a, Level 1b, etc.) could be a possible alternative to introducing Level 2 as a new series of amendments to the Regulation. The expert from EC emphasized the need of starting with the levels below to fill the gap in the European legislation in due time by 2017, whereas Level 2, currently artificial and likely to be time consuming to be defined due to its complexity, could be developed later on towards global harmonization. The secretariat reminded that the latest series of amendments to a Regulation (or its original version in the absence of series of amendments) were always subject to mutual recognition according to the 1958 Agreement.

34. GRPE endorsed the approach to focus first on the levels below (Level 1a, Level 1b, etc.) when developing the new Regulation on WLTP, while having in mind the need of Level 2 for IWVTA. GRPE agreed to further investigate the best way to integrate all levels in the new Regulation on WLTP and to resume discussion at the next GRPE session in June 2016.

35. The Chair of GRPE recommended that the structure of the new Regulation on WLTP should ensure the modular approach to take into account different levels. The expert from OICA was of the opinion that separation of modules could be helpful. The secretariat recalled the existence of safety Regulations structured according to one of the following options: a) modular approach in form of annexes corresponding to each of the levels, or b) single structure integrating the specifications of each level through tables in all relevant paragraphs.

36. The expert from EC wondered whether Japan would follow the provisions on the conformity of production to decide if these provisions could be directly inserted in the new Regulation on WLTP. The Chair of the IWG on Gaseous Fuelled Vehicles (GFV) mentioned that Annex 5 addressed specific additional requirements for GFV but he clarified that these requirements could also be included in the main annex on type 1 test.

37. GRPE endorsed the basic elements in GRPE-72-18 on the structure of both new Regulations (on WLTP and on other test types beyond type 1). GRPE noted the need to ensure a modular approach in the Regulation on WLTP with a general module on common provisions and specific modules adding further regional requirements.

38. Regarding the way forward on the transposition process, the expert from EC expressed his preference for setting up a Task Force reporting to the IWG on WLTP, rather than a new IWG reporting directly to GRPE. He underlined the relevance to have all Contracting Parties to the 1958 Agreement involved since the beginning to avoid the difficult integration of new elements at a later stage. The experts from Japan and India expressed their intention to participate in the Task Force.

39. GRPE endorsed the establishment of a new Task Force under the IWG on WLTP to deal with the transposition of GTR No. 15 into Regulations to be annexed to the 1958 Agreement. The Chair of GRPE invited Japan and the European Union to submit, as technical sponsors for these activities, an informal document to the March 2016 sessions of WP.29 and AC.3 to amend the proposed mandate for Phase 2 activities (ECE/TRANS/WP.29/2016/29) by including the established Task Force on the transposition process.

20. The expert from EC presented a status report on the WLTP Task Force dealing with the transposition of WLTP into the 1958 Agreement (GRPE-74-20). He informed that the Task Force had not met yet, but the first meeting would take place in February 2017. For the [adaptation] of the 1958 Agreement to include WLTP, he explained the intention was to follow a two-step approach: first, introduction of transitional provisions in Regulations Nos. 83 and 101 (see paras. 11-13 above); second, full transposition of GTR No. 15 into new Regulations under the 1958 Agreement. He recalled previous presentations by EC and the Secretariat on possible ways to structure these new Regulations (GRPE-72-18 and GRPE-73-26).

21. GRPE agreed to further discuss the transposition of WLTP into the 1958 Agreement at the next GRPE session on the basis of the work carried out by the WLTP Task Force dealing with this topic.
