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).

ISO 17225-5:2014(E)
Introduction
The objective of the ISO 17225 series is to provide unambiguous and clear classification principles for
solid biofuels; to serve as a tool to enable efficient trading of biofuels; to enable good understanding
between seller and buyer as well as a tool for communication with equipment manufacturers. It will also
facilitate authority permission procedures and reporting.
This part of ISO 17225 supports the use of graded firewood for residential, small commercial and public
building applications.
The residential, small commercial and public building applications require higher quality fuel for the
following reasons:
• Small-scale equipment does not usually have advanced controls and flue gas cleaning
• Appliances are not generally managed by professional heating engineers
• Appliances are often located in residential and populated districts
NOTE 1 Firewood produced according to this part of ISO 17225 may be used in stoves, fireplaces, cookers,
[1]
roomheaters and multifired sauna stoves, which are tested according to European standards EN 13229 ,
[2] [3] [4] [5] [6]
EN 12815 , EN 12809 , EN 13240 , EN 15250 and EN 15821 , and boilers systems tested according to
[7]
EN 303–5 .
NOTE 2 For individual contracts ISO 17225-1 can be used.
Although these product standards may be obtained separately, they require a general understanding of
the standards based on and supporting ISO 17225-1. It is recommended to obtain and use ISO 17225-1
in conjunction with these standards.

Table 1):
• 1.1.1 Whole trees without roots
• 1.1.3 Stem wood
• 1.1.4 Logging residues (thick branches, tops etc.)
• 1.2.1 Chemically untreated wood residues
