Description of BS 6043-2.1:1985 1985This International Standard specifies methods for sampling and preparation of samples from lots of calcined coke so as to obtain, with sufficient accuracy, a sample that is representative of the average qualities of each entire lot. It is applicable to cokes manufactured from pitch or petroleum intended specifically for use in the manufacture of electrodes used for the electrolytic production of aluminium. Because of the special requirements of these cokes, this International Standard includes provisions which do not appear in the methods for sampling similar carbonaceous products, such as metallurgical cokes. These provisions are mainly concerned with the composition of samples for physical measurements and for particle size analysis. The theoretical and practical aspects of sampling on which this International Standard is based are described more fully in ISO 1988 (coal) and ISO 2309 (metallurgical coke) and users are referred to these documents for greater detail. Because of processing considerations, it is essential that the product shall be of uniform chemical composition. Two samples should therefore be taken:
Applies to coke from either pitch or petroleum for use as electrodes in the electrolytic manufacture of aluminium.
