Metallic powders - Determination of apparent density - Part 1: Funnel method (ISO 3923-1:2018)

This document specifies the funnel method for the determination of the apparent density of metallic
powders under standardized conditions.
The method is intended for metallic powders that flow freely through a 2,5 mm diameter orifice. It
can, however, be used for powders that flow with difficulty through a 2,5 mm diameter orifice but flow
through a 5 mm diameter orifice.
Methods for the determination of the apparent density of powders that will not flow through a 5 mm
diameter orifice are specified in ISO 3923-2[1].

Metallpulver - Ermittlung der Fülldichte - Teil 1: Trichterverfahren (ISO 3923-1:2018)

Dieser Teil von ISO 3923 legt das Trichterverfahren zur Ermittlung der Fülldichte von Metallpulvern unter normierten Bedingungen fest.
Das Verfahren gilt für Metallpulver, die frei durch eine 2,5 mm-Ausfluss-Öffnung fließen. Es darf jedoch auch bei Pulvern angewendet werden, die schlecht durch eine 2,5 mm-Ausfluss-Öffnung, aber frei durch eine 5 mm-Ausfluss-Öffnung fließen.
Verfahren zur Ermittlung der Fülldichte von Pulvern, die nicht durch eine 5 mm-Ausfluss-Öffnung fließen, sind in ISO 3923 2 festgelegt.

Poudres métalliques - Détermination de la masse volumique apparente - Partie 1: Méthode de l'entonnoir (ISO 3923-1:2018)

Le présent document décrit la méthode dite de l'entonnoir, permettant de déterminer la masse volumique apparente des poudres métalliques dans des conditions normalisées.
Cette méthode s'applique aux poudres métalliques qui s'écoulent librement au travers d'un orifice de 2,5 mm de diamètre. Elle peut toutefois être utilisée pour des poudres qui s'écoulent avec difficulté au travers d'un orifice de 2,5 mm de diamètre mais librement au travers d'un orifice de 5 mm de diamètre.
Des méthodes de détermination de la masse volumique apparente des poudres qui ne s'écoulent pas au travers d'un orifice de 5 mm de diamètre sont spécifiées dans l'ISO 3923‑2[1].

Kovinski praški - Ugotavljanje navidezne gostote - 1. del: Preskus z lijakom (ISO 3923-1:2018)

Ta dokument določa preskus z lijakom za ugotavljanje navidezne gostote kovinskih praškov pri standardnih pogojih.
Metoda je namenjena za kovinske praške, ki so prosto pretočni skozi odprtino s premerom 2,5 mm. Kljub temu se lahko uporablja za praške, ki težko prehajajo skozi odprtino s premerom 2,5 mm, vendar so prosto pretočni skozi odprtino s premerom 5 mm.
Metode za določanje navidezne gostote praškov, ki niso pretočni skozi odprtino s premerom 5 mm, so določene v standardu ISO 3923-2 [1].
