PMP Inter-laboratory Correlation Exercise: Report on PART3: JRC Tests in July '06

This document reports the results of the third part of the testing performed during the PMP interlaboratory exercise 13 July to 18 August 2006 conducted at the Vehicles Emissions Laboratory (VELA2) in the Transport and Air Quality Unit of the European Commission’s Joint Research Centre (JRC-Ispra). This report presents the results of the work undertaken on a 2.0 HDi diesel car equipped with a Diesel Particulate Filter (DPF), i.e. the Golden Vehicle. Most of the tests complied with all the requirements of the document UN-GRPE PMP Phase 3. Inter-laboratory Correlation Exercise: Framework and Laboratory Guide. The measurements included both filter based particulate mass measurements and real-time particle number measurements performed under transient conditions on a chassis dynamometer. Extra tests were conducted in order to investigate the effect of the PMP recommendations over the legislated procedures (filter media, temperature, cyclone, no backup filter). Moreover the regeneration emissions were investigated. Finally comparisons with the previous measurements of the same vehicle in JRC were made. Mission of the JRC The mission of the JRC is to provide customer-driven scientific and technical support for the conception, implementation and monitoring of EU policies. As a service of the European Commission, the JRC functions as a reference centre of science and technology for the Union. Close to the policy-making process, it serves the common interest of the Member States, while being independent of special interests, whether private or national.
