| Summary: | This document describes procedures for the determination of non-rare earth impurities in individual rare earth metals and their oxides through the use of inductively coupled plasma atomic emission spectroscopy (ICP-AES). Magnesium (Mg), aluminum (Al), silicon (Si), calcium (Ca) and iron (Fe) are included as non-rare earth impurity elements, and the measurement ranges for each impurity element are specified. The applicable measurement range (mass fraction %) of magnesium, aluminum, silicon and calcium is from 0,001 to 0,2, and that of iron is from 0,001 to 0,5. The verified measurement ranges in the interlaboratory tests are described later in this document. Le présent document décrit des modes opératoires pour la détermination d’impuretés non-terres rares dans les métaux de terres rares individuels et leurs oxydes par spectrométrie d’émission atomique à plasma à couplage inductif (ICP-AES). Le magnésium (Mg), l’aluminium (Al), le silicium (Si), le calcium (Ca) et le fer (Fe) sont présents sous forme d’impuretés élémentaires dans les terres rares, et les plages de mesure de chacune de ces impuretés élémentaires sont spécifiées. La plage de mesure applicable (fraction massique en %) du magnésium, de l’aluminium, du silicium et du calcium est comprise entre 0,001 et 0,2, et celle du fer entre 0,001 et 0,5. Les plages de mesure vérifiées dans le cadre des essais interlaboratoires sont indiquées plus loin dans le présent document. Dieses Dokument beschreibt Verfahren für die Bestimmung von Verunreinigungen, die keine seltenen Erden sind, in einzelnen Seltenerdmetallen und ihren Oxiden durch die Anwendung von optischer Atomemissionsspektroskopie mit induktiv gekoppeltem Plasma (ICP-OES). Magnesium (Mg), Aluminium (Al), Silicium (Si), Calcium (Ca) und Eisen (Fe) werden als Nicht-Seltenerd-Verunreinigungselemente betrachtet und die Messbereiche für jedes Verunreinigungselement sind festgelegt. Der anwendbare Messbereich (Massenanteil in %) von Magnesium, Aluminium, Silicium und Calcium ist von 0,001 bis 0,2, und der von Eisen von 0,001 bis 0,5. Die in Ringversuchen überprüften Messbereiche werden später in diesem Dokument beschrieben. WARNUNG — Bei der Anwendung dieses Dokuments können gefährliche Chemikalien, Substanzen, Arbeitsgänge und Geräte angewendet werden. Dieses Dokument beabsichtigt nicht, auf etwaige Sicherheitsprobleme einzugehen, die mit deren Gebrauch zusammenhängen. Es liegt in der Verantwortung des Anwenders dieses Dokuments, entsprechende Sicherheits- und Gesundheitsvorkehrungen zu treffen und Beschränkungen, die sich aus gesetzlichen Vorschriften ergeben, vor der Anwendung zu bestimmen (z. B. nach ISO 15202 2 und ISO 15202 3). |
