Moteurs de poids lourds — Détermination, sur cycle transitoire, des émissions de polluants gazeux par mesure des concentrations dans les gaz d'échappement bruts et des émissions de particules en utilisant un système de dilution partielle

ISO 16183 specifies methods for the measurement and evaluation of gaseous and particulate exhaust emissions from heavy-duty engines under transient conditions on a test bed. The procedures it defines can be applied to any transient test cycle that does not require extreme system response times; it can therefore be used as an option to the regulated measurement equipment (usually CVS-type systems) of certification test cycles (e.g. ETC and FTP), with the approval of the certification agency.

ISO 16183 is applicable to heavy-duty engines for commercial vehicles primarily designed for road use, but can also be applied to passenger car engines and to engines used for non-road applications. The test equipment specified can also be applied to steady-state test cycles, however, if so, the calculation procedures will need to be replaced by those applicable to the particular test cycle.
