Characterization of bulk materials - Determination of a size-weighted fine fraction and crystalline silica content - Part 2 : calculation method

Le présent document spécifie la détermination par calcul de la fraction fine pondérée par taille (SWFF) et de la fraction fine de silice cristalline pondérée par taille (SWFFCS) dans des matériaux en vrac. Le document décrit également les hypothèses et les conditions préalables à respecter pour que cette méthode soit valable. L'objectif du présent document est de permettre aux utilisateurs d'évaluer des matériaux en vrac en ce qui concerne leur fraction fine pondérée par taille et leur teneur en silice cristalline.
