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.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 238, Solid biofuels, in collaboration with
the European Committee for Standardization (CEN) Technical Committee CEN/TC 335, Solid biofuels, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 18122:2015), which has been technically
revised.
The main changes are as follows:
— more detailed descriptions of the ashing furnace and ashing procedure;
— repeatability and reproducibility performance data updated;
— several references updated;
— minor editorial corrections.

ISO 18122:2022(E)
Introduction
Ash content is an important parameter for fuel deliveries since ash is a by-product of combustion and
ends up as bottom ash or fly-ash and needs to be removed. Depending on the jurisdiction, ash may be
deposited or used for production of other products or as fertilizer. Knowing how much ash comes with a
fuel can have economic consequences. Since the chemical composition of ash contributes to slagging and
corrosion in the combustion equipment, it is therefore important to know the amount of ash contained
in a fuel. Other testing standards are used for determining the chemical composition of ash.
