DESCRIPTION

BS EN ISO 28439:2011


This standard BS EN ISO 28439:2011 Workplace atmospheres. Characterization of ultrafine aerosols/nanoaerosols. Determination of the size distribution and number concentration using differential electrical mobility analysing systems is classified in these ICS categories:
  • 13.040.30 Workplace atmospheres

This International Standard provides guidelines for the determination of the number concentration and size distribution of ultrafine aerosols and nanoaerosols by use of mobility particle sizers (also called differential mobility analysers). Only the particle fraction of the aerosol is considered. For ultrafine aerosols and nanoaerosols, exposure metrics such as the number and surface area concentration are important.

This International Standard also gives guidelines for the determination of workplace exposure to ultrafine aerosols and nanoaerosols.

Specifically, the differential mobility analysing system (DMAS), now available from several vendors, is discussed. 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, which need to be addressed when limit values are fixed and compliance measurements carried out.
