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.
