Chemical analysis of refractory products - Part 4: Products containing silica and/or alumina (Analysis by Flame Atomic Absorption Spectrometry (FAAS) and Inductively Coupled Plasma Atomic Emission Spectrography (ICP)
This European Prestandard applies to refractory materials in the alumino- silicate familiy. It is intended for the determination of the following constituents within the following range: SiO2: 40 to 93 %; Al2O3: 1 to 60 %; Fe2O3: 0 to 10 %; TiO2, CaO, MgO, K2O, Na2O: 0,01 to 5 %. Note 1: Though Fe2O3 contents higher than 5 % are quite unusual in refractory materials, the field of application of this standard extends to 10 % Fe2O3. Note 2: Using FAAS, K andNa are determined in emission mode.
Chemische Analyse von feuerfesten Erzeugnissen - Teil 4: Silicium(IV)-oxid und/oder Aluminiumoxid enthaltende Erzeugnisse (Analyse mittels Flammen Atomabsorptionsspektrometrie (FAAS) und Atomabsorptionsspektrographie mit induktiv gekoppeltem Plasma (ICP))
Diese Europäische Vornorm ist für feuerfeste Werkstoffe aus der Gruppe der Alumosilicate anwendbar. Sie ist für die Bestimmung der folgenden Bestandteile innerhalb des angegebenen Massenanteil-Bereiches vorgesehen:SiO2 , 40 bis 93 %, Al2O3, 1 bis 60 %, Fe2O3, 0 à 10 %,TiO2;CaO;MgO;K2O;Na2O, 0,01 bis 5 %. ANMERKUNG 1: Obwohl Massenteile an Fe2O3 von mehr als 5 % bei feuerfesten Erzeugnissen sehr selten vorkommen, erstreckt sich der Anwendungsbereich dieser Europäischen VOrnorm bis auf einen Massenteil von 10% Fe2O3. AMERKUNG 2: K und Na werden bei der FAAS in Emission bestimmt.
Analyse chimique des produits réfractaires - Partie 4: Produits contenant de la silice et/ou de l'alumine (Analyse par spectrométrie d'absorption atomique dans la flamme (SAAF) et par spectrographie d'émission à plasma inductif (ICP))
Cette prénorme européenne s'applique aux matériaux réfractaires de la famille silice-alumine. Il concerne la détermination des constituants suivants, dans la gamme de concentration suivante: SiO2, 40 à 93 % - Al2O3, 1 à 60 % - Fe2O3, 0 à 10 % - TiO2;CaO;MgO;K2O;Na2O, 0,01 à 5 %. NOTE 1: Bien que des teneurs en Fe2O3 > à 5% soient tout à fait inhabituelles pour les matériaux réfractaires, le domaine d'application de cette prénorme européenne s'étend jusqu'à des teneurs égales à 10 % d'oxyde de fer. NOTE 2: Avec la SAAF, le potassium et le sodium sont déterminés par émission.
