Solid Biofuels - Determination of major elements
This Technical Specification describes methods for the determination of major elements of solid biofuels respectively of their ashes, which are Al, Ca, Fe, Mg, P, K, Si, Na, Ti. The determination of barium (Ba) and manganese (Mn) is also possible with the methods described in this Technical Specification.
The Standard includes 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.

This Technical Specification (CEN/TS) was approved by CEN on 22 November 2005 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This Technical Specification (CEN/TS 15290:2006) has been prepared by Technical Committee CEN/TC 335
“Solid biofuels”, the secretariat of which is held by SIS.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.
Introduction
The elements described as major elements of solid biofuels are in fact major elements of the fuel ashes more
than of the fuels. The determination of these elements may be helpful to predict the melting behaviour and
slagging of the ashes. Moreover, contamination of fuel with sand or soil is indicated by high values of several
elements.
In this Technical Specification, wet chemical methods are described. As an alternative, X-ray fluorescence
(XRF) may be used when validated with suitable materials (biomass reference materials).
1 Scope
This Technical Specification describes methods for the determination of major elements of solid biofuels
respectively of their ashes, which are Al, Ca, Fe, Mg, P, K, Si, Na, Ti. The determination of barium (Ba) and
manganese (Mn) is also possible with the methods described in this Technical Specification.
The Standard includes 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.
