Proposal from the Particle Measurement Programme informal group to:

• Modify the existing solid PN measurement methodology having a 50% cut-off size at 23 nm (SPN23) in order to allow the use of catalyzed volatile particle remover (VPR) and introduce minor improvements, and
• Include as a second option a solid PN measurement methodology with a 65% cut-off size at 10 nm (SPN10).

Proposal to update the PMP mandate with a view to delivering the following results:

• Proposal for a new methodology for exhaust PN measurement with a d50 cut-off size reduced to 10 nm: June 2020
• 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)
• Proposal for a common test procedure for the measurement of particle brake emissions from conventional ICE LDVs: December 2021.

Document submitted by the Informal Working Group (IWG) for the Particle Measurement Programme to inform and update the GRPE on work to amend UN GTR 15 Annexes 5, 6, 7 to:

• Modify the existing solid PN measurement methodology having a 50% cut-off size at 23 nm (SPN23) in order to allow the use of catalyzed volatile particle remover (VPR) and introduce minor improvements,
• Include as a second option a solid PN measurement methodology with a 65% cut-off size at 10 nm (SPN10).

Explanatory note from the PMP informal group addressing the proposed changes to the current methodology and the proposed changes for the second alternative option to extend the particle size detection range to 10 nm particles.

The TF Chair reported on the plan for the transposition of GTR15 (WLTP) and GTR19 (Evap) into a new UN Regulation.

The update provides a summary of the key updates to GTR15 which are proposed for Amendment 6. These cover the following topics:
updates to existing GTR15 requirements and new Optional Annexes for Type 5 test (durability), Type 6 test (low temperature) and Conformity of Production. There is a proposed new annex for OBD.
