Vehicle Emissions Certification Testing
At a glance
At the end of development programmes and before an operating license is issued, new vehicles must be tested and certified. In recent years, emissions regulations have become significantly more challenging, with the introduction of the WLTC process and RDE, and Millbrook is here to help.


Millbrook offers climatic emissions chassis dynamometer, sealed housing for evaporative emissions determination (SHED), and Real Driving Emissions (RDE) testing. It covers all the latest European and most of the Chinese emission certification tests and its facilities meet a range of regulatory requirements (see below), providing customers with the confidence that the facilities used for development are the same as they will use for certification.

Millbrook has many years of experience in certification testing and actively supports its customers with flexible timeframes, expert advice and world-class facilities.
