ISO 16000-27:2014
Indoor air -- Part 27: Determination of settled fibrous dust on surfaces by SEM (scanning electron microscopy) (direct method)
Product Details
For the purpose of ISO 16000-27:2014, an asbestos or fibrous structure is defined as an asbestos or (other inorganic/organic) fibre-containing particle regardless of its diameter.
The use of the sampling method described is limited, depending on the structure and type of the surface (minor roughness and curvature) and the thickness of dust layer. If the dust layer is too thick, the dust layer can be sampled by other means and eventually analysed as powder sample.
It is assumed that the settled dust has particle diameters mostly below 1 mm.
