Particle Number Counters

Due to a tendency to check Particle Number in the exhaust of Diesel vehicles to check correct operation of Diesel Particle Filters the need for instruments is increasing.

NMi took the lead in the VERT group to draft a Proposal for Particle Number Counters used in Periodical Technical Inspection (PTI). In The Netherlands this Proposal is already implemented in the national Regulation vehicles. Belgium included the Proposal in a national tender. The Proposal is also very close to the Swiss regulation for Particle Number Counters for machinery.

From now on NMi can examine these instruments and when the instrument passes the examinations a national type examination certificate together with a certificate according to the Proposal.
