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 com-
mittees. 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 liai-
son with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 12984 was prepared by Technical Committee ISO/TC 47, Chemistry, Subcommittee
SC 7, Aluminium oxide, cryolite, aluminium fluoride, sodium fluoride, carbonaceous products for the aluminium in-
dustry.

INTERNATIONAL STANDARD ISO 12984:2000(E)
Carbonaceous materials used in the production of aluminium —
Calcined coke — Determination of particle size distribution
1 Scope
This International Standard 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 pro-
cedure can be applied to consignments of calcined anthracite. This International Standard cannot be applied to frac-
tions 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 typically less than 10 %. This International
Standard is not applicable to determining particle sizes below 0,25 mm where a specific test for dust should be used.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publica-
tions do not apply. However, parties to agreements based on this International Standard are encouraged to investi-
gate the possibility of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain reg-
isters of currently valid International Standards.
