ISO 18227:2014规定了通过能量色散X射线荧光光谱法（EDXRF）或波长色散X射线荧光光谱法（WDXRF）定量测定均质固体废物、土壤和类土壤材料中的主要和微量元素浓度的程序，使用基体匹配标准进行校准。 ISO 18227:2014适用于以下元素: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和U。可根据所用元素和仪器测定约0000 1%到100%之间的浓度水平。

ISO 18227:2014 specifies the procedure for a quantitative determination of major and trace element concentrations in homogeneous solid waste, soil, and soil-like material by energy dispersive X-ray fluorescence (EDXRF) spectrometry or wavelength dispersive X-ray fluorescence (WDXRF) spectrometry using a calibration with matrix-matched standards. ISO 18227:2014 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. Concentration levels between approximately 0,000 1 % and 100 % can be determined depending on the element and the instrument used.
