Measurement of nanoscale and microscale fibrous materials at workplaces (part 1)
(in German)
A first stage has been completed in the development of a new measurement method for determining exposure to nanoscale and microscale fibrous materials. In this method, the nanoscale fibre diameter range down to 0.02 μm was considered separately in an initial convention. It was found that fibre counting must be performed in deviation from the filter surface area of 0.5 mm² specified for analysis in the Guideline VDI 3492 and the DGUV Information 213–546. The sampling duration and volume must be selected such that a large volume of air can be analysed and the analytical limit of detection thereby attained. The present first part of the article presents the above criteria for sampling and describes the parameters for analysis by scanning electron microscopy employing high-resolution apparatus and interpretation of the digitalized images.
