New EN 17507 helps improve measuring the emissions of road vehicles

Improving the way to measure particulate emissions of road vehicles, and thus contributing to reducing transport pollution? This is now possible, thanks to recently published standard EN 17507 ‘Road vehicles - Portable Emission Measuring Systems (PEMS) - Performance assessment’.

This standard, developed by 'CEN/TC 301 - Road vehicles', aims to qualify the measurement uncertainties of portable particle emission measurement systems (PEMS) used in real driving tests. The qualification of the different components of PEMS is of particular importance in the context of the tightening of particulate emissions thresholds. EU legislation foresees the definition of tolerated emission thresholds by taking measurements of an uncertainty factor, based on the objective precision of the portable measuring means. Thanks to the new standard, this precision is now set to improve and the uncertainty factor to be reduced.


The new EN 17507 provides the elements to assess this progression. With this new standard, CEN – the European Committee for European Standardization - brings a new contribution of European standardization to the efforts to address transport pollution, a major challenge in the context of the EU Green Deal.
