Metallic powders - Determination of oxygen content by reduction methods - Part 4: Total oxygen by reduction-extraction (ISO 4491-4:2013)

ISO 4491-4:2013 specifies a method for the determination of the total oxygen content of metallic powders by reduction-extraction at high temperature.
By agreement, this method is also applicable to the determination of the total oxygen content of sintered metal materials.
The method is applicable to all powders of metals, alloys, carbides, and mixtures thereof which are non-volatile under the test conditions. The sample may be in powder or compact form.
The analysis is carried out on the powder as supplied, but the method is not applicable if the powder contains a lubricant or binder. If such substances are present, the method may be used only if they can first be completely removed by a method not affecting the oxygen content of the powder.
ISO 4491-4:2013 is to be read in conjunction with ISO 4491-1.

Metallpulver - Bestimmung des Sauerstoffgehaltes durch Reduktionsverfahren - Teil 4: Gesamt-Sauerstoffgehalt durch Reduktionsextraktion (ISO 4491-4:2013)

Diese Norm legt ein Verfahren zur Bestimmung des Gesamt-Sauerstoffgehalts von Metallpulvern durch Reduktionsextraktion bei hoher Temperatur fest.
Nach Vereinbarung ist dieses Verfahren auch zur Bestimmung des Gesamt-Sauerstoffgehalts von Sinter-metallen anwendbar.
Dieses Verfahren gilt für alle Pulver aus Metallen, Legierungen, Carbiden und deren Mischungen, die unter den Versuchsbedingungen nicht flüchtig sind. Die Probe kann im Pulverzustand oder als Presskörper verwendet werden.
Das Verfahren wird auf das Pulver im Anlieferungszustand angewendet, es darf jedoch weder einen Gleit-mittelzusatz noch ein Bindemittel enthalten. Sind derartige Substanzen vorhanden, darf das Verfahren nur angewendet werden, wenn diese Substanzen vorher vollständig durch ein Verfahren entfernt werden, das den Sauerstoffgehalt des Pulvers nicht beeinträchtigt.
Die vorliegende Norm muss in Zusammenhang mit ISO 4491-1 angewendet werden.

Poudres métalliques - Dosage de l'oxygène par les méthodes de réduction - Partie 4: Oxygène total par réduction-extraction (ISO 4491-4:2013)

L'ISO 4491-4:2013 spécifie une méthode de dosage de l'oxygène total présent dans les poudres métalliques. Cette méthode procède par réduction, puis extraction de l'échantillon à haute température.
Par accord, cette méthode peut également être appliquée au dosage de l'oxygène total dans les matériaux métalliques frittés.
La présente méthode est applicable à toutes les poudres de métaux, d'alliages, de carbures et de mélanges de ces composés non volatils dans les conditions de l'essai. L'échantillon peut se trouver à l'état de poudre ou de comprimé.
L'analyse est menée sur la poudre à l'état de livraison, mais la méthode n'est pas applicable si la poudre contient un lubrifiant ou un liant. Si de telles substances sont présentes, la méthode ne peut être utilisée que si ces substances peuvent être totalement éliminées au préalable par une méthode n'affectant pas la teneur de la poudre en oxygène.
L'ISO 4491-4:2013 est prévue pour être utilisée conjointement avec l'ISO 4491-1.
