- What is this ISO 10312 - TEM for asbestos about?
ISO 10312 discusses ambient air with a focus on asbestos presence. ISO 10312 specifies a reference method using transmission electron microscopy for the determination of airborne asbestos fibres and structures in a wide range of ambient air situations, including the interior atmospheres of buildings, and for a detailed evaluation for asbestos structures in any atmosphere.
ISO 10312 provides a method that allows the determination of the types of asbestos fibres present and also includes measurement of the lengths, widths, and aspect ratios of the asbestos structures.
Note: The method cannot discriminate between individual fibres of asbestos and elongate fragments (cleavage fragments and acicular particles) from non-asbestos analogues of the same amphibole mineral.
Who is ISO 10312 - TEM for asbestos for ?
ISO 10312 on TEM for asbestos is useful for:
The construction industry / the housing industry
Testing laboratories
Health and safety personnel / building inspectors
Quality control personnel
Why should you use ISO 10312 - TEM for asbestos ?
Most fibres in ambient atmospheres are not asbestos and therefore, there is a requirement for fibres to be identified. Many airborne asbestos fibres in ambient atmospheres have diameters below the resolution limit of the optical microscope.
ISO 10312 is applicable to the determination of airborne asbestos in a wide range of ambient air situations, including the interior atmospheres of buildings, and for a detailed evaluation of any atmosphere.
