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.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

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 www .iso .org/

iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 238, Solid biofuels.

This second edition cancels and replaces the first edition (ISO 18122:2015), which has been technically

revised.
The main changes compared to the previous edition are as follows:

— The revision is required in order to provide more detailed descriptions of the ashing furnace and

ashing procedure, update the repeatability and reproducibility performance data, update several

references, and make other minor editorial corrections.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.

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 and knowing how much ash comes with a fuel

may have economic consequences. In addition, the chemical composition of ash contributes to slagging

and corrosion in the combustion equipment and 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.
