Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information

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 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 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.

INTERNATIONAL STANDARD ISO 16967:2015(E)
Solid biofuels — Determination of major elements — Al,
Ca, Fe, Mg, P, K, Si, Na and Ti
1 Scope
This International Standard 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 other
elements such as barium (Ba) and manganese (Mn) is also possible with the methods described in this
International Standard.
This International 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.
