EN ISO 16967:2015(E)DIN EN ISO 16967:2015-07 3 IntroductionThe elements described as major e
28、lements of solid biofuels are in fact major elements of the fuel ashes more than of the fuels. The determination of these elements can be used to assess ash behaviour in a thermal conversion process or to assess utilization of ashes. Moreover, fuel contamination or process additives are indicated by
29、 high values of certain elements. Contamination of fuel with sand or soil is indicated by high values of several elements.In this International Standard, wet chemical methods are described.EN ISO 16967:2015(E)DIN EN ISO 16967:2015-07 4 1 ScopeThis International Standard describes methods for the det
30、ermination of major elements of solid biofuels respectively of their ashes, which are Al, Ca, Fe, Mg, P, K, Si, Na, Ti. The determination of other elements such as barium (Ba) and manganese (Mn) is also possible with the methods described in this International Standard.This International Standard in
31、cludes two parts: Part A describes the direct determination on the fuel, this method is also applicable for sulfur and minor elements, Part B gives a method of determination on a prepared 550 C ash.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this

43、The sample is digested in a closed vessel by the help of reagents, temperature, and pressure. The digestion is either carried out directly on the fuel (part A) or on a 550 C prepared ash (part B).The detection of the elements can be done by ICP-OES, ICP-MS, FAAS, or FES.6 ReagentsAll reagents should
44、 be of analytical grade or better. If minor elements are also to be determined, the best qualities should be used.6.1 Water, containing negligible amounts of major elements, i.e. amounts that do not contribute significantly to the determinations. Deionised water will normally fulfil this requirement
45、.6.2 Nitric acid (HNO3), 65 % (w/w), = 1,41 g/ml.6.3 Hydrogen peroxide (H2O2), 30 % (w/w), = 1,11 g/ml.6.4 Hydrofluoric acid (HF), 40 % (w/w), = 1,13 g/ml.CAUTION Hydrofluoric acid might lead to health hazards.6.5 Boric acid (H3BO3), 4 % (w/w).6.6 Use of certified reference materials (CRM or SRM).Us
46、e certified reference materials, issued by an internationally recognized authority, to check if the accuracy of the calibration meets the required performance characteristics. Examples of certified reference materials are: NBS 1570 spinach leaves, NBS1571 orchard leaves, NBS 1573 tomato leaves, and
47、NBS 1575 pine needles.When, due to matrix effects or concentration range limitations, no good recoveries for the certified reference materials can be obtained, calibration with at least two CRM or SRM materials can solve these problems. In that case, CRM or SRM materials other than used for the calibration shall be used for verification purposes.NOTE A CRM or SRM is pr
