NF X43-262

Air quality. Workplace air. Gravimetric determination of particulate pollution deposits. Rotating disk method.

La présente norme décrit une méthode de prélèvement d'aérosols solides ayant pour but de recueillir une quantité représentative du dépôt alvéolaire définie dans le fascicule de documentation X 43-100. Cette méthode, largement utilisée dans les mines, commence à être utilisée en milieu industriel. Dans de nombreux environnements, elle peut constituer une alternative à la méthode décrite dans la norme NF X 43-259, relative à la détermination de la fraction alvéolaire des particules de l'aérosol, méthode de séparation par cyclone. La méthode convient dans tous les cas où l'aérosol est stable dans les conditions de prélèvement et de conservation avant la mesure finale.
