What is Ambient air - Determination of numerical concentration of inorganic fibrous particles - Scanning electron microscopy method about?
ISO 14966:2002 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. ISO 14966:2002 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. The range of concentrations for fibres with lengths greater than 5 micrometres, in the range of widths which can be detected under standard measurement conditions, is approximately 3 fibres to 200 fibres per squar
