Scope: This document sets out a wavelength dispersive X-ray fluorescence (XRF) procedure for the determination of silicon, aluminium, iron, calcium, magnesium, sodium, potassium, titanium, manganese, phosphorus and sulfur. The method is applicable to coal ashes, coke ashes and boiler ashes having components within the concentration ranges specified in Table 1. Table 1 — Ranges of application of the method Concentration range Oxide % 5 to 100 SiO2 Al2O35 to 80 Fe2O30,1 to 25 CaO 0,05 to 25 K 2O 0,05 to 5 MgO 0,05 to 25 Na2O 0,05 to 50,05 to 5 TiO2 Mn3O40,005 to 5 P2O5a 0,01 to 50,05 to 10ISO 3 NOTE 1 Additional analytes can be included in the method, provided that appropriate validation using reference materials is carried out. NOTE 2 The precision statistics can be determined using suitable reference materials. NOTE 3 The method described in this document has been tested for the following additional analytes: BaO (0,01 % to 1 %); SrO (0,01 % to 1 %) and ZnO (0,005 % to 1 %). a For information relating to phosphorus calculations, refer to Annex D.
