UNE-EN ISO 18227:2025

This document specifies the procedure for a quantitative determination of major and trace elementconcentrations in homogeneous solid waste, soil, soil-like material and sludge by energy dispersive X-rayfluorescence (EDXRF) spectrometry or wavelength dispersive X-ray fluorescence (WDXRF) spectrometryusing a calibration with matrix-matched standards.This document is applicable for the following elements: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni,Cu, Zn, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Ag, Cd, Sn, Sb, Te, I, Cs, Ba, Ta, W, Hg, Tl, Pb, Bi, Th and U. Concentrationlevels between approximately 0,000 1 % and 100 % can be determined depending on the element and theinstrument used.
