  • Millbrook’s purpose-built Portable Emissions Measurement System (PEMS) test workshop, with dedicated calibration area, is now in service
  • Completed to a high standard to enable flexibility to suit a variety of PEMS tests and meet increasing customer demand for vehicle emissions tests
  • Investment facilitates greater efficiency for Real Driving Emissions (RDE) tests by bringing everything together in one location

Millbrook has opened a purpose-built PEMS workshop next door to its other emissions measurement laboratories to offer greater flexibility for test programmes. Millbrook is well established as the leading independent and impartial provider of PEMS testing to the automotive sector and is approved to RDE package 3. It caters for light, heavy and off-road vehicles, providing crucial RDE measurements for pollutants including NOx, PN, and CO2.

The new emissions test facility includes a dedicated calibration area for the measurement equipment and climatic soak boxes with a temperature range of -20°C to +50°C for forced simulation of cold start conditions. The facility also has external parking bays with electric vehicle charging capability. The parking bays, located close to the proving ground exit, include power supplies so that vehicles can be prepared for ambient RDE tests from an ambient cold start and driven directly onto Millbrook’s extensive tracks and its RDE-compliant public routes.

Millbrook is currently running five regulation-compliant PEMS units on industry-critical RDE test programmes. These units are fully correlated to its 4WD climatic emissions chassis dynamometer, a legal requirement for certification testing, to ensure data validity. In addition, Millbrook’s engineers optimise how programmes are run to achieve accurate, same-day reporting of emissions test results to facilitate faster development of vehicle technologies.

We have a very busy vehicle emissions test facility in the UK, offering an exceptional combination of people, facilities and equipment. The new PEMS workshop significantly adds to the convenience and efficiency of conducting emissions tests at Millbrook.Phil Stones, Chief Engineer – Propulsion at Millbrook

As well as RDE testing, Millbrook extensively uses its PEMS equipment for product benchmarking and accreditation tests for programmes such as the HGV accreditation scheme and CVRAS.
