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).

Carbonaceous materials used in the production of
aluminium — Calcined coke — Determination of particle
size distribution
1 Scope
This document specifies a method for the determination of the particle size distribution of a sample of
coke having a typical size distribution as normally produced by calcination of delayed petroleum coke.
The same procedure is applicable to consignments of calcined anthracite. This document does not apply
to fractions of carbon material prepared by sieving and crushing or to filter fines.
This method is applicable to the determination of particle sizes ranging from 0,25 mm to 16 mm, as the
sum of the percentages of the size distribution above and below this range is typical
