Metallic powders - Determination of oxygen content by reduction methods - Part 4: Total oxygen by reduction-extraction (ISO 4491-4:2019)

This document 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 can 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.
This document is to be read in conjunction with ISO 4491-1.

Metallpulver - Bestimmung des Sauerstoffgehaltes durch Reduktionsverfahren - Teil 4: Gesamt-Sauerstoffgehalt durch Reduktionsextraktion (ISO 4491-4:2019)

Dieses Dokument 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-metallwerkstoffen anwendbar.
Dieses Verfahren gilt für alle Pulver aus Metallen, Legierungen, Carbiden und deren Mischungen, die unter den Prüfbedingungen nicht flüchtig sind. Die Probe kann im Pulverzustand oder als Presskörper vorliegen.
Die Analyse wird auf das Pulver im Anlieferungszustand angewendet, jedoch ist dieses Verfahren nicht anwendbar, wenn das Pulver Gleitmittel oder Bindemittel enthält. Sind derartige Substanzen vorhanden, darf das Verfahren nur dann angewendet werden, wenn diese Substanzen vorher vollständig durch ein Verfahren entfernt werden können, das den Sauerstoffgehalt des Pulvers nicht beeinträchtigt.
Dieses Dokument dient zur Verwendung in Verbindung mit ISO 4491-1.

Poudres métalliques - Dosage de l'oxygène par les méthodes de réduction - Partie 4: Oxygène total par réduction-extraction (ISO 4491-4:2019)

Le présent document 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.
Le présent document est prévu pour être utilisé conjointement avec l'ISO 4491-1.

Kovinski prah - Ugotavljanje deleža kisika z redukcijskimi metodami - 4. del: Skupni delež kisika z redukcijo-ekstrakcijo (ISO 4491-4:2019)

Ta dokument določa metodo za ugotavljanje skupnega deleža kisika v kovinskem prahu
z redukcijo-ekstrakcijo pri visoki temperaturi.
Po dogovoru se ta metoda uporablja tudi za ugotavljanje skupnega deleža kisika v sintranih
kovinskih materialih.
Metoda se uporablja za vse kovinske prahe, zlitine, karbide in njihove mešanice, ki so v preskusnih pogojih nehlapne. Vzorec je lahko v obliki prahu ali v trdni obliki.
Analiza se izvaja na dobavljenem prahu, vendar se metoda ne uporablja, če prah vsebuje mazivo ali vezivo. Če so takšne snovi prisotne, je mogoče metodo uporabiti samo, če je te snovi mogoče popolnoma odstraniti z metodo, ki ne vpliva na delež kisika v prahu.
Ta dokument se uporablja v povezavi s standardom ISO 4491-1.
