Proposal to clarify that the E10 reference fuel may still be used at the worst case for the Type IV test.
16. The representative from OICA introduced GRPE-82-08 proposing to amend the 05 and 06 series of amendments to UN Regulation No. 83 with respect to fuel specification alternatives for Type IV tests. The Chair of the IWG on Particle Measurement Programme (PMP) supported the proposal and agreed that testing with E10 fuel indeed represented a worst case scenario. The representative from OICA agreed and intended to prepare a working document for the next session of GRPE.
