Solid recovered fuels - Methods for the determination of the content of elements (Al, Ca, Fe, K, Mg, Na, P, S, Si, Ti, As, Ba, Be, Cd, Co, Cr, Cu, Hg, Mo, Mn, Ni, Pb, Sb, Se, Sn, Tl, V, Zn) (ISO 3884:2025)
This document specifies methods for the determination of major and minor element concentrations in solid recovered fuels after digestion by the use of different acid mixtures and by addition of a fluxing agent for solid recovered fuel (SRF) ash.
a) Method A: Microwave assisted digestion with hydrochloric, nitric and hydrofluoric acid mixture (6 ml HCl; 2 ml HNO3; 2 ml HF) followed by boric acid complexation;
b) Method AT: Microwave assisted digestion with hydrochloric, nitric and tetrafluoroboric acid mixture (6 ml HCl; 2 ml HNO3; 4 ml HBF4);
c) Method B: Microwave assisted digestion with hydrochloric, nitric and hydrofluoric acid mixture (0,5 ml HCl; 6 ml HNO3; 1 ml HF) followed by boric acid complexation;
d) Method BT: Microwave assisted digestion with hydrochloric, nitric and tetrafluoroboric acid mixture (0,5 ml HCl; 6 ml HNO3; 2 ml HBF4);
e) Method C: Microwave assisted digestion with nitric acid, hydrogen peroxide and hydrofluoric acid mixture (2,5 ml H2O2; 5 ml HNO3; 0,4 ml HF) and optional boric acid complexation;
f) Method CT: Microwave assisted digestion with nitric acid, hydrogen peroxide and tetrafluoroboric acid mixture (2,5 ml H2O2; 5 ml HNO3; 0,8 ml HBF4);
g) Method D: Digestion of the ashed SRF sample with fluxing agent lithium metaborate in an oven at 1 050 °C.
This document is applicable for the following major and minor/trace elements:
— Major elements: aluminium (Al), calcium (Ca), iron (Fe), potassium (K), magnesium (Mg), sodium (Na), phosphorus (P), sulfur (S), silicon (Si) and titanium (Ti).
— Minor/trace elements: arsenic (As), barium (Ba), beryllium (Be), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), mercury (Hg), molybdenum (Mo), manganese (Mn), nickel (Ni), lead (Pb), antimony (Sb), selenium (Se), tin (Sn), thallium (Tl), vanadium (V) and zinc (Zn).
Method A is applicable for general use for SRF and ashed SRFs, but the amount of the test portion can be very low in case of high concentration of organic matter. Method AT can be used if an alternative to HF is necessary.
Method B with a higher volume of nitric acid is applicable for SRFs with high organic matter (e.g. suitable for high plastic content) that can be difficult to digest with less nitric acid or as a substitute for method A if appropriate equipment is not available. Method BT can be used if an alternative to HF is necessary.
Method C with combination of nitric acid and hydrogen peroxide and addition of hydrofluoric acid is applicable for wood based SRFs (e.g. demolition wood) or when there is a need for comparability to solid biofuel standards. Method CT can be used if an alternative to HF is necessary.
Method D is specifically applicable for determination of major elements in ashed SRF samples.
XRF can be used for the analysis of major elements (Al, Ca, Fe, K, Mg, Na, P, S, Si, Ti) after ashing (815 °C) of the samples and several major and minor/trace elements in SRF can be analysed by XRF after suitable calibration provided that the concentration levels are above instrumental detection limits of the XRF instrumentation and after proper preliminary testing and validation.
Digestion methods with HF and subsequent boric acid complexation or application of method D are applicable for determination of Si and Ti (better digestion efficiency).
Alternative digestion methods can be applied, if their performance is proved to be comparable with those of the methods described in this document.

Combustibles solides de récupération - Méthodes de détermination de la teneur en éléments (Al, Ca, Fe, K, Mg, Na, P, S, Si, Ti, As, Ba, Be, Cd, Co, Cr, Cu, Hg, Mo, Mn, Ni, Pb, Sb, Se, Sn, Tl, V, Zn) (ISO 3884:2025)
Le présent document spécifie les méthodes pour la détermination des concentrations en éléments majeurs et mineurs dans les combustibles solides de récupération après digestion par l'utilisation de différents mélanges d'acides et par l'ajout d'un fondant pour la cendre de combustible solide de récupération (CSR).
a) Méthode A: Digestion assistée par micro-ondes avec un mélange d'acides chlorhydrique, nitrique et fluorhydrique (6 ml de HCl, 2 ml de HNO3 et 2 ml de HF) suivie d'une complexation de l'acide borique.
b) Méthode AT: Digestion assistée par micro-ondes avec un mélange d'acides chlorhydrique, nitrique et tétrafluoroborique (6 ml de HCl, 2 ml de HNO3 et 4 ml de HBF4).
c) Méthode B: Digestion assistée par micro-ondes avec un mélange d'acides chlorhydrique, nitrique et fluorhydrique (0,5 ml de HCl, 6 ml de HNO3 et 1 ml de HF) suivie d'une complexation de l'acide borique.
d) Méthode BT: Digestion assistée par micro-ondes avec un mélange d'acides chlorhydrique, nitrique et tétrafluoroborique (0,5 ml de HCl, 6 ml de HNO3 et 2 ml de HBF4).
e) Méthode C: Digestion assistée par micro-ondes avec un mélange d'acide nitrique, de peroxyde d'hydrogène et d'acide fluorhydrique (2,5 ml de H2O2, 5 ml de HNO3 et 0,4 ml de HF) et d'une complexation optionnelle de l'acide borique.
f) Méthode CT: Digestion assistée par micro-ondes avec un mélange d'acide nitrique, de peroxyde d'hydrogène et d'acide tétrafluoroborique (2,5 ml de H2O2, 5 ml de HNO3 et 0,8 ml de HBF4).
g) Méthode D: Digestion de l'échantillon de CSR réduit à l'état de cendres avec un fondant de type métaborate de lithium dans un four à 1 050 °C.
Le présent document s'applique aux éléments majeurs et mineurs/traces suivants:
— éléments majeurs: aluminium (Al), calcium (Ca), fer (Fe), potassium (K), magnésium (mg), sodium (Na), phosphore (P), soufre (S), silicium (Si) et titane (Ti);
— éléments mineurs/traces: arsenic (As), baryum (Ba), béryllium (Be), cadmium (Cd), cobalt (Co), chrome (Cr), cuivre (Cu), mercure (Hg), molybdène (Mo), manganèse (Mn), nickel (Ni), plomb (Pb), antimoine (Sb), sélénium (Se), étain (Sn), thallium (Tl), vanadium (V) et zinc (Zn).
La méthode A est applicable pour une utilisation générale pour les CSR et les CSR réduits à l'état de cendres, mais la quantité de la prise d'essai peut être très faible en cas de forte concentration de matière organique. La méthode AT peut être utilisée si une alternative au HF est nécessaire.
La méthode B, avec un volume d'acide nitrique plus important, est applicable pour les CSR à forte teneur en matière organique (teneur élevée en matières plastiques par exemple) qui peuvent être difficiles à digérer avec moins d'acide nitrique, ou comme substitut à la méthode A si l'équipement approprié n'est pas disponible. La méthode BT peut être utilisée si une alternative au HF est nécessaire.
La méthode C, une combinaison d'acide nitrique et de peroxyde d'hydrogène avec ajout d'acide fluorhydrique, est applicable pour les CSR à base de bois (bois de démolition, par exemple) ou lorsqu'il est nécessaire de les comparer aux normes relatives aux biocarburants solides. La méthode CT peut être utilisée si une alternative au HF est nécessaire.
La méthode D est applicable spécifiquement à la détermination des éléments majeurs dans les échantillons de CSR réduits à l'état de cendres.
La fluorescence de rayons X (XRF)peut être utilisée pour l'analyse des éléments majeurs (Al, Ca, Fe, K, Mg, Na, P, S
