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.
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 part of ISO 12985 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 12985-1 was prepared by Technical Committee ISO/TC 47, Chemistry, Subcommittee
SC 7, Aluminium oxide, cryolite, aluminium fluoride, sodium fluoride, carbonaceous products for the aluminium
industry.
ISO 12985 consists of the following parts, under the general title Carbonaceous materials used in the production of
aluminium — Baked anodes and cathode blocks:
� Part 1: Determination of apparent density using a dimensions method
� Part 2: Determination of apparent density and of open porosity using a hydrostatic method

Part 1:
Determination of apparent density using a dimensions method
1 Scope
This part of ISO 12985 specifies a dimensions method for the determination of the apparent density of carbonaceous
products used in the production of aluminium.
This method is applicable to samples with a simple or well-defined geometry (cylindrical, rectangular parallelepipedical,
cubic, etc.) and having a smooth surface profile. The accuracy of measurement is strongly influenced by the equipment
used for sampling, i.e. the drilling and sawing machines.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this part of ISO 12985. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 12985 are encouraged to investigate 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
registers of currently valid International Standards.
