Metallic powders - Determination of flow rate by means of a calibrated funnel (Hall flowmeter) (ISO 4490:2014)

ISO 4490:2014 specifies a method for determining the flow rate of metallic powders, including powders for hard metals, by means of a calibrated funnel (Hall flowmeter). The method is applicable only to powders which flow freely through the specified test orifice.

Metallpulver - Ermittlung der Durchflussdauer mit Hilfe eines kalibrierten Trichters (Hall flowmeter) (ISO 4490:2014)

Diese Internationale Norm legt ein Verfahren zur Ermittlung der Durchflussrate metallischer Pulver, einschließ-lich Hartmetallpulver, mit Hilfe eines kalibrierten Trichters (Hall flowmeter) fest.
Dieses Verfahren ist nur auf Pulver anwendbar, die frei durch die festgelegte Ausflussöffnung des Prüftrichters fließen.

Poudres métalliques - Détermination du temps d'écoulement au moyen d'un entonnoir calibré (appareil de Hall) (ISO 4490:2014)

L'ISO 4490:2014 spécifie une méthode de détermination du taux d'écoulement des poudres métalliques, y compris les poudres pour métaux-durs, au moyen d'un entonnoir calibré (appareil de Hall). La méthode n'est applicable qu'aux poudres qui s'écoulent librement par l'orifice d'essai spécifié.

Kovinski praški - Ugotavljanje pretočnosti s pomočjo umerjenega lijaka (Hallov merilnik) (ISO 4490:2014)

Ta mednarodni standard določa metodo za ugotavljanje pretočnosti kovinskih praškov, vključno s praški za trde kovine, s pomočjo umerjenega lijaka (Hallov merilnik). Metoda se uporablja samo za praške, ki so prosto pretočni skozi določeno preskusno odprtino.
