Abstract

The guideline specifies a method for the determination of the number concentration of fibre structures in settled dust on surfaces and for the classification of these structures (e.g. chrysotile, amphibole asbestos, other inorganic fibres). Sampling is carried out using an adhesive medium (e.g. tape), which is pressed onto the surface to be examined. The analysis is done using SEM/EDXA. The method is primarily used for indoor applications, but is also suitable for certain outdoor situations (e.g. window sills). The assessment of the measuring results is based on a semi-quantitative scheme. The detection limit of the method is approx. 40 fibre structures per cm2 of surface.
