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 on the meaning of ISO specific terms and expressions related to conformity
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.
The committee responsible for this document is ISO/TC 238, Solid biofuels.
ISO 18134 consists of the following parts under the general title Solid biofuels — Methods for the
determination of moisture content — Oven dry method:
— Part 1: Total moisture — Reference method
— Part 2: Total moisture — Simplified method
— Part 3: Moisture in general analysis sample

INTERNATIONAL STANDARD ISO 18134-1:2015(E)
Solid biofuels — Determination of moisture content —
Oven dry method —
Part 1:
Total moisture — Reference method
1 Scope
This part of ISO 18134 describes the method of determining the total moisture content of a test sample
of solid biofuels by drying in an oven and may be used when high precision of the determination of
moisture content is necessary. The method described in this International Standard is applicable to all
solid biofuels. The moisture content of solid biofuels (as received) is always reported based on the total
mass of the test sample (wet basis).
NOTE The term moisture content, when used with biomass materials, can be misleading since untreated
biomass frequently contains varying amounts of volatile compounds (extractives) which might evaporate when
determining moisture content by oven drying (see References [2] and [3]).
