ABSTRACT: Solid particle number emissions have been regulated in a wide range of automotive fields. Its technical regulations require annual calibration of a particle number counting system because a standard like span gas with a known particle number concentration does not exist. However, the calibration does not fully ensure the validity of the measurements during the annual usage interval. This paper proposes a methodology of on-site checks of the particle number counting system with a particle generator so that its measurement values can be validated during the interval of the calibration.
