DIN EN 16897:2017 Edition

For occupational exposure to ultrafine aerosols and nanoaerosols, exposure metrics like the number and surface area concentration are important. This European Standard provides a guideline to determine the occupational exposure to airborne particles (expressed as number concentration of ultrafine aerosols and nanoaerosols) by use of condensation particle counters (also called CPCs). Principles of operation, problems of sampling in the workplace environment, calibration, equipment maintenance, measurement uncertainty, and reporting of measurement results are covered. Potential problems and limitations are described.
