| Document title | PMP: Proposal for sub-23nm particles measurement procedure for HD engines | ||||||||||
| Date | 11 Jan 2021 | This proposal from IWG PMP is based on the PN measurement procedure laid down in UN R49 but should be considered exclusively a technical working document. The purpose of this document is only to discuss within the PMP group the changes/additions needed to modify the PN cut-off size from 23 to approximately 10 nm and to include raw exhaust sampling | |||||||||

38. The representative from the EC, Chair of the IWG on PMP, introduced GRPE-82-29-Rev.1 and GRPE-82-30, presenting a draft proposal for sub-23nm measurement procedure for heavy duty engines in the laboratory. He mentioned the intention of the IWG on PMP was to finalize the procedure and submit a document that could be used as a reference document for future use in regulatory texts. After considering different document types during the session, he declared this document would be proposed as a draft consolidated resolution in forthcoming sessions of GRPE. |
