Proposal to permit the use of the calibration and maintenance intervals from UN GTR No. 15 for test facilities capable of testing to that UN GTR.

Proposal to correct errors and clarify provisions in the draft UN Regulation on WLTP.

Proposal to correct errors and clarify provisions of the draft 01 series of amendments to the draft UN Regulation on WLTP.

UNR WLTP having features that have not been seen before in Regulations of the 1958 Agreement and GRPE therefore decided to commission this document to assist all users of this Regulation in their understanding. UNR WLTP will have 3 Levels. There are two regional Levels (contained within Level 1), and one harmonised Level (Level 2). The regional Levels reflect the current (at the time of adoption) emissions legislation in the EU (Level 1A) and in Japan (Level 1B). The harmonised level is the only level which will be accepted as part of an approval to Regulation 0 (International Whole Vehicle Type Approval – IWVTA)

• Proposal for HD raw exhaust PN sampling and extension of sub-23 nm procedure to HD engines: January 2021
• Proposal for LD PN-PEMS 10 nm specifications : June 2021 (tbc)
