Solid recovered fuels - Determination of elemental composition by X-ray fluorescence (ISO 22940:2021)

This document specifies the procedure for a determination of major and minor element concentrations in solid recovered fuel material by energy-dispersive X-ray fluorescence (EDXRF) spectrometry or wavelength-dispersive X-ray fluorescence (WDXRF) spectrometry using a calibration with solid recovered fuel reference materials or solid recovered fuel samples with known content. A semiquantitative determination can be carried out using matrix independent standards.
This document is applicable to the following elements: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Mo, Cd, Sb, Sn, Tl and Pb. Concentration levels between approximately 0,000 1 % and 100 % can be determined depending on the element, the calibration materials used and the instrument used.
NOTE            X-ray fluorescence spectrometry can be used as a fast method for a qualitative overview of elements and impurities and after suitable calibration it is very useful for determining major elements or even minor elements (except Hg) in order to quickly identify increased concentrations of minor elements in solid recovered fuels (SRF), for example during SRF-production.

Feste Sekundärbrennstoffe - Bestimmung der Elementzusammensetzung durch Röntgenfluoreszenz (ISO 22940:2021)

Dieses Dokument legt ein Verfahren zur Bestimmung der Konzentrationen von Haupt- und Nebenelementen in Material von festen Sekundärbrennstoffen durch energiedispersive Röntgenfluoreszenz-Spektrometrie oder wellenlängendispersive Röntgenfluoreszenz-Spektrometrie unter Anwendung einer Kalibrierung mit Referenzmaterialien für feste Sekundärbrennstoffe oder Proben von festen Sekundärbrennstoffen mit bekanntem Gehalt fest. Eine semiquantitative Bestimmung kann unter Verwendung matrixunabhängiger Standards durchgeführt werden.
Dieses Dokument ist anwendbar auf die folgenden Elemente: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Mo, Cd, Sb, Tl und Pb. In Abhängigkeit von dem Element, den verwendeten Kalibriermaterialien und dem verwendeten Gerät können Konzentrationsniveaus zwischen etwa 0,000 1 % und 100 % bestimmt werden.
ANMERKUNG Die Röntgenfluoreszenz-Spektrometrie kann als ein schnelles Verfahren für einen qualitativen Überblick über Elemente und Verunreinigungen angewendet werden und ist nach einer geeigneten Kalibrierung sehr nützlich für die Bestimmung von Hauptelementen oder sogar Nebenelementen (außer Hg), um schnell erhöhte Konzentrationen von Nebenelementen in festen Sekundärbrennstoffen (SRF, en: solid recovered fuels) zu identifizieren, zum Beispiel während der SRF-Produktion.

Combustibles solides de recupération - Détermination de la composition élémentaire par fluorescence de rayons X (ISO 22940:2021)

Le présent document spécifie la méthode de détermination des concentrations d'éléments majeurs et mineurs dans un matériau de combustible solide de récupération par spectrométrie de fluorescence X à dispersion d'énergie (EDXRF) ou par spectrométrie de fluorescence X à dispersion de longueur d'onde (WDXRF) à partir d'un étalonnage avec des matériaux de référence ou des échantillons de combustibles solides de récupération dont la teneur est connue. Une détermination semi-quantitative peut être effectuée en utilisant des étalons ne dépendant pas de la matrice.
Le présent document s'applique aux éléments suivants: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Mo, Cd, Sb, Sn, Tl et Pb. Il est possible de déterminer des niveaux de concentration de l'ordre de 0,000 1 % et 100 % en fonction de l'élément, des matériaux d'étalonnage employés et du spectromètre utilisé.
NOTE            La spectrométrie de fluorescence X peut être utilisée pour obtenir rapidement une vue générale qualitative des éléments et impuretés et, après un étalonnage approprié, se révèle très utile pour déterminer les éléments majeurs ou même les éléments mineurs (sauf le Hg) afin d'identifier rapidement les concentrations accrues d'éléments mineurs dans les combustibles solides de récupération (CRF) (par exemple, lors de la production de CSR).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was dra
