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 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 14422 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.

Carbonaceous materials used in the production of
aluminium — Cold-ramming pastes — Methods of sampling
1 Scope
This International Standard describes methods and conditions for sampling of cold-ramming pastes used in
aluminium manufacture.
2 Normative reference
The following normative document contains provisions which, through reference in this text, constitutes provisions
of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard 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.
ISO 6257, Carbonaceous materials used in the production of aluminium — Pitch for electrodes — Sampling.
3 Terms and definitions
For the purposes of this International Standard, the terms and definitions given in ISO 6257 and the following
apply.
3.1
cold-ramming paste
mixture containing graded carbonaceous aggregate and bonding materials which harden when heated to form a
carbonaceous bond
NOTE Such a mixture needs to be installed at or near ambient temperature by the use of mechanical or pneumatic tools or
vibration.
3.2
increment
amount of material taken from a sample unit in a single operation with a sampling device
3.3
test portion
amount of material taken from the laboratory sample and prepared in a manner suitable for use in a particular
determination
3.4
sample unit
item
defined quantity of material having a boundary
NOTE 1 The boundary may be physical, for example a container, or temporal, for example a particular time or time interval in
the case of a stream of material.
© ISO 1999 – All rights reserved 1
NOTE 2 A number of sample units may be gathered together, for example in a package or box.
NOTE 3 In English, the terms "item", "unit" and "individual" are sometimes used as synonyms for "sample unit". In French, the
term "individu" is sometimes used as a synonym for "unité d'échantillonnage".
4 General
The type of sampling equipment, and the preparation and reduction of the samples, which should not alter the
properties to be determined, shall be agreed between the contracting parties.
When sampling material in movement, do so during loading or unloading of the consignment or while packaging
units are being filled (see 6.4.5).
During sampling, sample division, and the preparation and storage of samples, protect the samples from any
factors which may cause changes in the properties to be determined.
