Air quality - Determination of the asbestos fiber concentration by transmission electron microscopy - Indirect method

Le présent document décrit une méthode de référence, la microscopie électronique à transmission, associée à l'analyse par spectrométrie en dispersion d'énergie des rayons X, pour la détermination de la concentration en fibres d'amiante dans les atmosphères ambiantes. Cette méthode comprend les procédures de prélèvement et de préparation des échantillons qui conduisent à une concentration sélective des fibres d'amiante et une élimination des matériaux organiques, hydrosolubles et acido-sensibles, ainsi que les procédures d'analyse.
