Poudres métalliques — Détermination de l'aptitude à l'écoulement au moyen d'un entonnoir calibré (Appareil de Hall)

Abstract / scope

The method is applicable only to powders which flow freely through the specified test orifice. It measures the time required for 50 g of a metallic powder to flow through the orifice of a calibrated funnel. Specifies apparatus, calibration of the funnel, sampling, procedure, expression of results and test report.
