Ekspozimi ndaj vendit të punës - Karakterizimi i aerosolëve/nanoaerosoleve shumë të imët- Përcaktimi i përqëndrimit të numrit duke përdorur numëruesit e grimcave të kondensimit

Workplace exposure - Characterization of ultrafine aerosols/nanoaerosols - Determination of number concentration using condensation particle counters

Scope

This European Standard gives guidelines on the measurement of the fine particle fraction of the aerosol, especially for the determination of the number concentration of ultrafine aerosols and nanoaerosols at workplaces by use of condensation particle counters (CPC).

This European Standard deals with the CPC's principle of operation, problems of sampling in the workplace environment, aspects for selecting a suitable instrument, limits of application, use of different working fluids and technologies, calibration, equipment maintenance, measurement uncertainty, and reporting of measurement results. Potential problems and limitations which are of relevance for workplace measurements are described.
