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.

Regulation (EU) 2016/1628, also known as the NRMM Regulation or Stage V Regulation, restructures the EU regulation of non-road mobile machinery ranging from lawn mowers to snow mobiles to bulldozers, but excludes agricultural machinery (to be subjected to a separate EU regulation). In order to maintain the alignment between UN Regulations on emissions and EU emissions regulations, the EC proposes GRPE work on a new series of amendments to UN R96 (and by extension UN R120) for publication in 2018.

Proposal, subject to endorsement by the GRPE during its January 2017 session, to permit Contracting Parties applying UN R101 and GTR No. 15 (WLTP) to refuse type approvals granted under UN R101 as an alternative to compliance with their national/regional legislation from the date of entry into force of Supplement 7 to the 01 series of amendments to UN R101.

In line with the need to update UN R96 in response to the new EU Stage V NRMM regulation, Regulation (EU) 2016/1628 would impact UN R132. Therefore, EUROMOT recommends updating UN R132 in parallel with UN R96 and UN R120. In particular, EUROMOT proposes establishing a specific annex to UN R132 in light of the similar stringencies of EURO VI heavy duty emissions requirements and those of NRMM Stage V that would specify all the necessary additional requirements for Stage V (in a manner similar to the existing Annex 12 for emission levels equivalent to the 06 series of amendments of UN R49).

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.

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.

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.

Proposal to ensure that all replacement pollution control devices conform with the intent of UN R49 and to align UN R49 in this regard with Regulation (EU) 2016/1718. CLEPA proposes the establishment of a new annex under UN R49-05 R.49-05 to restrict the approval of a replacement device to one that “enables the engine and vehicle to comply with the rules with which it was originally in compliance”.

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.”

WLTP informal working group refinements to the amendment proposal.

Complete version of GTR No. 15 including the proposed Amendment 2 (GRPE/2017/7) and latest refinements by the WLTP informal group (GRPE-74-02). Amendment 2 corresponds to phase 2a development of the GTR, including the following modification to the text:

1. If an alternative value is applied for a parameter, such as a higher n_min_drive or an ASM, this parameter value has to be the same within an interpolation family (Paragraph 5.6.1.).
2. The mass in running order used for the calculation of the power to mass ratio is replaced by mass in running order minus 75 kg (paragraph 1. of Annex 1).
3. Idle engine speed n_idle is removed from the power curve measurement requirement (paragraph 2. of Annex 2).
4. The additional safety margin (ASM) value may be decided by manufacturer rather than the prescribed exponential curve (paragraph 3.4. of Annex 4).
5. The number of decimal place of road load coefficients is defined (paragraph 2.4. of Annex 4).
6. Additional restrictions are set to the application of the split run method for coastdown testing (paragraph 4.3.1.3.4. of Annex 4).
7. Specific data rejection criteria are added (paragraph 4.3.1.4.3. of Annex 4).
8. The “delta method” for road load determination is added (paragraph 6.8. of Annex 4 and other paragraphs. See section 4.4.25.for more detail).
9. The roller radius correction factor is modified(paragraph 6.6.3. of Annex 4).
10. The allowable combination of the test vehicle selection and family requirements are further clarified (paragraph 4.2.1.3. of Annex 4 and other paragraphs of Annex 4).
11. Provisions for an additional cooling fan are included(paragraph 1.1.5. and 1.1.6. of Annex 5).
12. The correction of measurement/recording frequency requirements are specified (over several annexes).
13. Calculation of the n/v ratio is defined (paragraph 8. of Annex 7).
14. The stepwise procedure for calculating the final test results of OVC-HEVs is added (paragraph 4.6. of Annex 8).

European Commission report on the effort to transpose the GTR on light vehicle emissions into UN type approval regulations, including handling of current UN Regulations on emissions (notably, UN R83 and UN R101) and process for implementing the WLTP requirements.

Proposal to add the following paragraph to the draft amendment presented in document WP.29/2016/87:

9. Entry into force

The provisions set in Revision 2 to Rule No. 1 on uniform provisions for Periodical Technical Inspections of wheeled vehicles with regard to the protection of the environment shall enter into force on 1 June 2018.

Report on the status of the International Whole Vehicle Type Approval program with regard to regulations under the purview of GRPE.
