40. The Chair of the IWG on PMP introduced GRPE-81-13 on a revision of the Terms of References (ToRs) of the IWG to include on-road test procedure definitions, which are expected to be developed for light- and heavy- duty application concerning the sub-23 nm PN emissions. GRPE agreed to revise the ToRs of the IWG on PMP as proposed in GRPE-81-13.
