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 part of ISO 12986 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 12986-1 was prepared by Technical Committee ISO/TC 47, Chemistry, Subcommittee
SC 7, Aluminium oxide, cryolite, aluminium fluoride, sodium fluoride, carbonaceous products for the aluminium in-
dustry. ISO 12986-1 describes a three-point method which is applicable to prebaked anodes, but which may be used
for cathode blocks. A further method is being developed as ISO 12986-2, which will describe a four-point method for
use with cathode blocks only.
ISO 12986 consists of the following parts, under the general title Carbonaceous materials used in the production of
aluminium — Prebaked anodes and cathode blocks:
— Part 1: Determination of bending/shear strength by a three-point method
The determination of bending/shear strength by a four-point method will be the subject of a future part 2 to
ISO 12986.

INTERNATIONAL STANDARD ISO 12986-1:2000(E)
Carbonaceous materials used in the production of aluminium —
Prebaked anodes and cathode blocks —
Part 1:
Determination of bending/shear strength by a three-point method
1 Scope
This part of ISO 12986 describes a method for the determination of the bending/shear strength (flexural strength) of
� �
prebaked anodes and cathode blocks at temperatures in the range 20C3to 0 C. The method is particularly appli-
cable to prebaked anodes, but can be applied to cathode blocks.
NOTE For the practical application of this International Standard the terms 'bending/shear strength' and 'flexural strength' may be
considered equivalent.
