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.
International Standard ISO 8007-1 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 8007 consists of the following parts, under the general title, Carbonaceous materials used in the production of
aluminium — Sampling plans and sampling from individual units:
 Part 1: Cathode blocks
 Part 2: Prebaked anodes
Part 3, which is in preparation, will give procedures for sampling sidewall blocks.

Introduction
Details of the sampling of shaped refractory products in general are given in ISO 5022, which gives the statistical
basis for sampling plans for acceptance testing of a consignment or lot.
Cathode blocks used in the production of aluminium have specific requirements for sampling and, while the
statistical basis for sampling given in ISO 5022 applies, further or modified requirements also apply.
