NEN-ISO 14966

Ambient air - Determination of numerical concentration of inorganic fibrous particles - Scanning electron microscopy method

inactive
Organization: NEN
Publication Date: 1 January 2003
Status: inactive
Page Count: 52
ICS Code (Ambient atmospheres): 13.040.20
scope:

This International Standard specifies a method using scanning electron microscopy for determination of the concentration of inorganic fibrous particles in the air. The method specifies the use of gold-coated, capillary-pore, track-etched membrane filters, through which a known volume of air has been drawn. Using energy-dispersive X-ray analysis, the method can discriminate between fibres with compositions consistent with those of the asbestos varieties (e.g. serpentine and amphibole), gypsum, and other inorganic fibres. Annex C provides a summary of fibre types which can be measured. This International Standard is applicable to the measurement of the concentrations of inorganic fibrous particles in ambient air. The method is also applicable for determining the numerical concentrations of inorganic fibrous particles in the interior atmospheres of buildings, for example to determine the concentration of airborne inorganic fibrous particles remaining after the removal of asbestos-containing products.
