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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 14427 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.

INTERNATIONAL STANDARD ISO 14427:2004(E)

Carbonaceous materials used in the production of aluminium —
Cold and tepid ramming pastes — Preparation of unbaked test
specimens and determination of apparent density after
compaction
1 Scope
This International Standard describes the preparation of unbaked test specimens made by compacting
carbonaceous ramming pastes. It also includes a method for the determination of the apparent density after
compaction.
Unbaked test specimens of ramming paste need to be prepared not only for the determination of the apparent
density of the paste after compaction, but also for the determination of the dimensional change during baking
and for the subsequent determination of properties of baked test specimens.
