This guidance document is a JRC technical support document, contributing to the development of best practices with PEMS. It shall be used primarily for the preparation, the execution and the follow-up of the emissions tests with PEMS on road heavy-duty vehicles (HDV) equipped with conventional combustion engines (gasoline, diesel, CNG, LPG).
