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 20202 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 20202:2004(E)

Carbonaceous materials used in the production of aluminium —
Cold and tepid ramming pastes — Preparation of baked test
pieces and determination of loss on baking
1 Scope
This International Standard describes a method of baking green test specimens made by compacting
carbonaceous ramming pastes. It includes the baking procedure (heating rate and holding time) and the
determination of the loss on baking (relative mass loss).
Baked test specimens of ramming paste need to be prepared for the determination of properties after baking,
for instance apparent density, crushing strength and porosity.
