UN Regulation WLTP
This document presents a draft of the potential structure
and content of a new UNR WLTP.
Rob Gardner, TRL - September 2018
WLTP-24-03e
Appendix
UNR WLTP: Section 1 - Scope
Scope
and Application (?) [consider expanding title beyond just “Scope”]
This UN Regulation applies to the type approval of vehicles of categories M1, M2, N1 and N2 with a
reference mass not exceeding [2,610 kg] with regard to the WLTP Type 1 test for criteria emissions [
or
use “
emissions of gaseous compounds, particulate matter, particle number
”
] and to emissions of carbon
dioxide and fuel consumption and/or the measurement of electric energy consumption and electric
range, to the Type 4 test for Evaporative Emissions and to the Type 5 test for verifying the durability of
pollution control devices.
This Regulation does not lay down rules for the Type II test, Type III test, Type VI test, in-service
conformity, or On-Board Diagnostic (OBD) systems.
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.
[Dark red text below is from UNR101]
It does not apply to a category N1 vehicle if both:
(a) The engine type fitted to that type of vehicle has received type approval pursuant to Regulation No.
49, and
(b) The total annual worldwide production of N1 vehicles of the manufacturer is less than 2,000 units.
Equivalent approvals (???)
The following do not need to be approved to this Regulation – vehicles above 2,380 kg to which
approvals to UNR 49 have been granted as an extension.

Standard UNR text
UNR WLTP: Appendix 1
Verification of conformity of
production for Type 1 test—statistical method
Level 1a – Align with EU 2017/1151 as amended by the 2nd Act
Level 1b – under development
Level 2 - TBD

Production for EVs
Level 1a – Align with EU 2017/1151 as amended by the 2nd Act
Level 1b – under development

UNR WLTP: Appendix 3
Requirements for vehicles that use a

07 series Appendix 6 update)
Level 1b – Currently no requirement in Japan. Can consider but may not be needed in
Japan. TBD
Level 2 - TBD
NB: Appendices 3-5 in UNR83 cover In-Service Conformity and have been deleted
for UNR WLTP as ISC will be in UNR83 08 series. UNR83 Appendix 6 (SCR) therefore
now becomes Appendix 3.
NB2: SCR requirements may be added to GTR15. If that happens then this appendix
would be moved to Annexes Part B WLTP.
UNR WLTP: Annexes Part A
Annex A1: Engine and vehicle characteristics and information concerning the
conduct of tests
– this will exclude all the specific ‘non-Type 1/Type 4 info’ that is
currently in UNR 83 07 series (e.g. Section 3.2.12.2.7. OBD).
NB: there will be a lot of duplication between the information documents for UNR
WLTP and UNR83 08 if we take this approach. May need a novel approach.

This document details the transposition of GTR15 (WLTP) and GTR19 (Evap) into UN Regulations, focusing on the scope, definitions, and application for approval of vehicle categories M1, M2, N1, and N2. It outlines requirements for emissions testing, carbon dioxide, fuel consumption, electric energy consumption, and more, while also addressing specific conditions for type approval extension. The regulations also exempt certain vehicles and specify equivalent approvals. Sections cover scope, definitions, and application procedures, referencing EU regulations and incorporating Japan-specific details.

WLTP-24-03e Appendix UN Regulation WLTP This document presents a draft of the potential structure and content of a new UNR WLTP. Rob Gardner, TRL - September 2018
UNR WLTP: Section 1 - Scope Scope and Application (?) [consider expanding title beyond just Scope ] This UN Regulation applies to the type approval of vehicles of categories M1, M2, N1 and N2 with a reference mass not exceeding [2,610 kg] with regard to the WLTP Type 1 test for criteria emissions [or use emissions of gaseous compounds, particulate matter, particle number ] and to emissions of carbon dioxide and fuel consumption and/or the measurement of electric energy consumption and electric range, to the Type 4 test for Evaporative Emissions and to the Type 5 test for verifying the durability of pollution control devices. This Regulation does not lay down rules for the Type II test, Type III test, Type VI test, in-service conformity, or On-Board Diagnostic (OBD) systems. 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. [Dark red text below is from UNR101] It does not apply to a category N1 vehicle if both: (a) The engine type fitted to that type of vehicle has received type approval pursuant to Regulation No. 49, and (b) The total annual worldwide production of N1 vehicles of the manufacturer is less than 2,000 units.
