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 18123:2014), which has been technically
revised.The main changes are as follows:
— “ISO 21945, Solid biofuels – Simplified sampling method for small scale applications” has been added
to the list of Normative References— The Standard specifies that the entire procedure shall be done in duplicate
— EN Standards have been replaced by ISO Standards
— Minor editorial corrections

Introduction
The volatile matter is determined as the loss in mass, less that due to moisture, when a solid biofuel
is heated out of contact with air under standardised conditions. The test is empirical and, in order
to ensure reproducible results, it is essential that the rate of heating, the final temperature, and the
overall duration of the test are carefully controlled. It is also essential to exclude air from the solid
biofuel during heating to prevent oxidation. The fit of the crucible lid is therefore critical. The moisture
content of the general analysis sample is determined at the same time as the volatile matter so that the
appropriate correction can be made.© ISO 2022 – All rights reserved

DRAFT INTERNATIONAL STANDARD ISO/DIS 18123:2022(E)
Solid biofuels — Determination of volatile matter
1 Scope
This International Standard aims to define the requirements and method used to determine the volatile
matter of solid biofuels. It is intended for persons and organisations that manufacture, plan, sell, erect
or use machinery, equipment, tools, and entire plants related to solid biofuels, and to all persons and
organisations involved in producing, purchasing, selling, and utilizing solid biofuels.
The volatile matter is determined as the loss in mass, less that due to moisture, when solid biofuel is
subject to partial pyrolysis under standardized conditions.2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
