Proposal to improve the text of provisions introduced in Amendment 3 to UN GTR No.4.

Proposal suggests that 2 new series of amendments are necessary: 83.08 to cover ISC for the WLTP Test and 83.09 to add ISC for the new UNR „RDE“ (which also has no ISC requirements) because Contracting Parties should be free to apply UNR 154 and UNR "RDE“, each with or without ISC without connection
A Contracting Party applying UNR 154 and UNR 83.08 but not UNR "RDE“ would be obliged to conduct or at least monitor RDE ISC in the absence of 83.09

EPPR IWG proposes to draft the UN GTR on durability based upon the European Regulation No. 168/2013 and its supplementing regulations (Euro 5) to provide test procedures and requirements for the durability of after-treatment devices.

Proposal identifies 2 concerns:
“Coasting“ – Coasting is defined in GTR 15 and UNR 154 and must be deactivated for testing, may raise concerns for the approval of many hybrid vehicles and for conventional vehicles with modern start stop systems.
“Single roller dynamometer in 4WD operation“ – This combination is forbidden by GTR 15 and UNR 154 for the Type 1
test. There appears to be no reason for this ban (restraint systems must meet requirements for all configurations) other than an assumption that the configuration is not used for type 1 testing

This proposal aims at harmonizing the text of UN Regulation No. 83 and UN Regulation No. 101. Furthermore, one error was found in the formulas used for the calculation of a NEDC road load values from those determined according to UN GTR No. 15 (WLTP) and one wrong cross reference in the 01 series of amendments to UN Regulation No. 101.
1. Harmonization of UN Regulation No. 83 (Annex 4a, Appendix 7b, paragraph 1.) and UN Regulation No. 101 (Annex 7, Appendix 2, paragraph 1.); in Annex 7, Appendix 2, paragraph 1. Vehicles in general are not approved according to UN GTR No. 15, therefore the text phrase of UN R83 is recommended.
2. Correction of wrong reference to Annex 4 instead of Annex 7 of UN GTR No.15; in Annex 7, Appendix 2, paragraph 2.1.(b).
3. When copying the methodology from EU regulation, a ‘.’ was wrongly introduced instead of a ‘-‘ in the formula.

Proposal to amend Annex 7 – Appendix 2 paragraph 1., to provide the road load power calculation method that may be used

Proposes a shortened Test Procedure NEDC for PEV and alternative for conformity of procedure.

The presentation supports the proposal for a Shortened Test Procedure NEDC for PEV acc. to WLTP (including adding PEV COP procedure alternative).

Proposal by IWG EVE (Electric Vehicles and the Environment) of the draft text for a new UN GTR on in-vehicle battery durability for electrified vehicles.

This explanatory note by IWG PMP, updates on the proposals for solid particle number (SPN) measurements for the type approval of heavy-duty engines. The explanatory note addresses (i) the changes to the current SPN23 methodology, (ii) the proposed changes for the second alternative option to extend the particle size detection range to 10 nm particles, (iii) the proposed changes to allow direct SPN sampling with fixed dilution ratio.

Proposes to amend the scope to clarify that UN R 49-06 series engine certification (corresponding to Euro VI) have no smoke and does not include the certification according to UN Regulation 24.
