Proposal to correct and clarify the text, including to

1. correct the constants for equation (34) to calculate exhaust mass flow using carbon balance method,
2. correct constants used for CVS verification,
3. correct the formula for regression analysis according to Annex 4, Appendix 3, and
4. correct the rise time (to 3.5 s from 2.5 s) for the PEM analyzers under paragraph A.2.2.1. of the 06 series.

Comprehensive amendment of document GRPE/2017/6 to align UN R49 with the latest amendments of EU Euro VI legislation (Reg. EU 2016/1718), including

1. OBD equivalency option for light commercial vehicles to be continued with step ‘D’,
2. editorial corrections (incl. keeping optional THC PEMS measurement for gas engines),
3. implementation dates in Appendix 9 table 1 (2016/1718) and Annex 3 table 1 (R49),
4. implement rejection note for retroactive applicability with regard to in-service conformity (paragraph 13.4.),
clarification of type approval provisions for ‘new vehicle types as of 2017’,
5. deletion of infeasible requirement related to the PEMS test (“…void if … no valid windows left in urban only”), second part of sentence in Annex 8, Appendix 1: A1.4.2.2.2.2.
6. deletion of inconsistency between work based window and CO2 mass based method regarding valid integration windows (A.1.4.2.2.2.2. versus A.1.4.3.1.2.2).

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 to restrict the application of CO2 specific emission limits only to NMHC and CO emissions (back-to-back comparison of NOx and PM to apply under the regulation in any case). The proposal also aligns the text where applicable with the intent of paragraph 2.3.15.: “R49 original emission limits” means the emission limits as defined in Regulation No. 49 to which the original engine system was approved."

Proposal to correct an error in the formula presented in paragraph 5.4.2. Diesel engines – Factor αd. The parameter “f_m” in the equation should be a superscript (e.g., meaning “to the power of f_m”). Through a transcription error, this factor was rendered in normal text.
