Advanced technical ceramics - Methods of test for ceramic powders - Part 3: Determination of the oxygen content of non-oxides by thermal extraction with a carrier gas
This part of EN 725 describes a method for the determination of the oxygen content of non-oxide powders used for advanced technical ceramics, using an inert carrier gas thermal extraction method. The method described is suitable for oxygen contents of less than 3 %.
NOTE An indication of the limits of determination is usually given by the manufacturers of the gas analysis apparatus used. However, for a specific measurement procedure, such limits can be determined by experiments conducted by the user.
Hochleistungskeramik - Prüfverfahren für keramische Pulver - Teil 3: Bestimmung des Sauerstoffgehaltes in Nichtoxid-Pulvern mittels Trägergasheißextraktion
Dieser Teil von EN 725 beschreibt ein Verfahren zur Bestimmung des Sauerstoffgehaltes mittels Trägergasheißextraktion in Nichtoxidpulvern, die für Technische Keramik verwendet werden. Das Verfahren ist anwendbar für Sauerstoffgehalte < 3 %.
ANMERKUNG Die Grenzwerte für die Bestimmung sind von den Geräteherstellern vorgegeben. Für spezielle Messverfahren müssen sie durch eigene Versuche bestimmt werden
Céramiques techniques avancées - Méthodes d'essais pour poudres céramiques - Partie 3: Détermination de la teneur en oxygene de poudres non-oxydes par extraction a chaud sous gaz porteur
La présente partie de l’EN 725 décrit une méthode de détermination de la teneur en oxygène de poudres non-oxydes utilisées dans les céramiques techniques avancées, par extraction à chaud sous gaz porteur inerte. La méthode présentée est applicable aux teneurs en oxygène inférieures à 3 %.
NOTE Généralement, les fabricants de l’appareil d’analyse du gaz utilisé indiquent les limites de la détermination. Cependant, pour un mode opératoire de mesure particulier, ces limites peuvent être déterminées au cours des expériences conduites par l’utilisateur.
