ABSTRACT
This document describes a standard method for determining particle number size distributions in outside air in the size range from 10 nm to 800 nm at total concentrations of up to about 10 ^ 5 cm ^ -3 with a temporal resolution of a few minutes. The standard procedure is based on a mobility particle size spectrometer (MPSS), which is operated with a bipolar diffusion charger and a condensation particle counter (CPC) as a detector. This document specifies the performance characteristics and minimum requirements for the devices and equipment to be used and describes sampling, operation, data processing and QA / QC measures, including calibration.
