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/

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

This second edition cancels and replaces the first edition (ISO 17225-3:2014), which has been technically

revised. The main changes compared to the previous edition are as follows:
— raw material basis enlarged
— values for chemical properties changed

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 document supports the use of graded wood briquettes 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 districts

NOTE 1 Wood briquettes produced according to this document can 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 this document can 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 this document.
