1 Scope This International Standard provides guidelines on the determination of aerosol particle size distribution by means of the analysis of electrical mobility of aerosol particles. This measurement is usually called “differential electrical mobility analysis for aerosol particles”. This analytical method is applicable to particle size measurements ranging from approximately 1 nm to 1 µm. This International Standard does not address the specific instrument design or the specific requirements of particle size distribution measurements for different applications, but includes the calculation method of uncertainty . In this International Standard, the complete system for carrying out differential electrical mobility analysis is referred to as DMAS ( differential mobility analysing system ), while the element within this system that classifies the particles according to their electrical mobility is referred to as DEMC ( differential electrical mobility classifier ).
NOTE For differential electrical mobility measurements relating to Road Vehicle applications, please refer to relevant national and international standards. ISO Technical Committee TC 22, Road vehicles , is responsible for developing International Standards relating to road vehicles, components and measurements.
