ASBESTOS IN COATED ROADSTONE - IDDRIM
Detection and identification of asbestos in coated roadstone through IDDRIM method.
À propos de cette analyse
ANALYSIS METHODS
La détection d'amiante ainsi que l'identification du type de fibre concerné se fait par The detection of asbestos as well as the identification of the fiber type in question is done by optical microscope and/or transmission electron microscopy (TEM) for the coated roadstone. These two methods are done after calcination and acid treatment before a TEM observation.
TECHNIQUES AND MATERIALS EMPLOYED
Calcination, acid attack, and filtration before the 3 test sample analysis.
Petrographic microscope
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
ESTIMATED TIME
3 days or 5 days
SAMPLING
Samples packed in a waterproof double sealing bag (ziplock).
NORMS AND REFERENCE
Method defined by IDRIMM (appendix G-7 of the USIRF guide), adapted from the NFX 43-050 norm.
