Euro 6: emission measurements (chassis dynamometer, PEMS), autonomy...

The Euro 6 standard includes several revisions: Euro 6b, Euro 6c or Euro 6.2, Euro 6d-TEMP including Euro 6d-TEMP-EVAP-ISC, Euro 6d or Euro 6d Full which widen the envelope of required tests and lower the limits of pollution emissions (limits of NOx (nitrogen oxides), CO (carbon monoxide), fine particles (PM/PN) and unburned hydrocarbons (HC)).

From January 1, 2021, the Euro 6.d Full standard is strengthening the limit on pollutant emission limits that must not be exceeded. Carbon monoxide (CO), hydrocarbons (HC), or nitrogen oxide (NOx) are particularly targeted.All types of engines are concerned: diesel and petrol cars, as well as those with a hybrid or LPG engine.


Our Osny site is accredited to EN 17025 for exhaust emissions testing on a chassis dynamometer and for exhaust emissions testing on an open road (RDE) for light vehicles (CO2 / CO / NOx / Particulate Matter / Consumption measurements)

Euro 6 : The main requirements

Since 2014, the Euro 6 standard  has been applied and has also evolved with, among other things, the increase in testing in real driving conditions. A vehicle must now pass a series of tests concerning:

  • exhaust emissions (gazeous and particulate) in laboratory (WLTC) and real driving conditions (RDE), emissions in low ambient temperature, idling emissionsexhaust gas opacity, the right operation and the regeneration of subsequent treatment systems
  • evaporative emissions (EVAP tests) and crankcase emissions;
  • on-board diagnostics systems and performance in use of pollution control devices  - Alert in case of malfunction of the pollution control systems (OBD);
  • sustainability of pollution control devices;
  • In-Service Conformity (ISC Tests)
  • the energy consumption indicator (OBFCM and FCM)

The WLTC is a dyno-based cycle, similar to the NEDC cycle. However, the WLTC aims to correct the weaknesses of the NEDC. It includes stronger acceleration and higher average speed. Nevertheless, being a laboratory test, there is always a gap between the consumption evaluated during the test and the one reached in reality.
