ASBESTOS IN COATED ROADSTONE – TEM
Detection and identification of asbestos in coated roadstone
À propos de cette analyse
ANALYSIS METHODS
The detection of asbestos as well as the identification of the fiber type in question is done transmission electron microscopy (TEM) on the samples after a double-chemical treatment.
TECHNIQUES AND MATERIALS EMPLOYED
Transmission electron microscopy (TEM) : analysis of the fiber’s morphology and additional analysis by electron diffraction and energy dispersive X-ray spectroscopy.
NATURE OF THE RESULTS
The results are qualitative: presence or absence, identification of one or many types of asbestos in case of presence.
ESTIMATED TIME
1 day, 3 days or 5 days
SAMPLING
Samples packed in a waterproof double sealing bag (ziplock).
NORMS AND REFERENCE
Method defined by IDRIMM adapted from the NFX 43-050 norm.
FURTHER INFORMATION
Sample preparation is done without any mechanical grinding, the aim being to prevent an analysis bias by creating fragments.
