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).

Introduction
This document specifies a method for manual determination of the fines content in pellets. The fines
content is defined as the percentage in mass of material below 3,15 mm in size (measured with a round
hole perforated metal plate sieve according to ISO 3310-2). The fines content is an important parameter
since excessive amounts of fines in consignments of pellets can cause problems either in transportation
systems or during combustion, or both. It also can cause health problems if the dust is inhaled and
it increases the risk of dust explosions. Many of these problems are connected to the tendency of
stratification of fines caused by any movement of the pellets.
Annex A describes a procedure for determining the amount of coarse pellet fines
(3,15 mm ≤ CPF < 5,6 mm). The determination of the amounts of smaller fines particles, for example the
fractions < 1 mm and < 0,5 mm, is given in Annex B.
NOTE 1 The upper limit of 5,6 mm for CPF was chosen because a sieve with an aperture diameter of 5,6 mm is
the standard commercial sieve with the next-smallest aperture diameter after 6 mm, which corresponds to the
diameter of the standard pellet size. When conducting the procedure for CPF as outlined in Annex A, additional
CPF are created as a result of the sieving procedure. Test results are therefore indicative and best used for
comparative purposes rather than treated as CPF originally present in the sample.
NOTE 2 This document will replace ISO 18846.
