8、1:1985 ii BSI 10-1999 National foreword This British Standard has been prepared under the direction of the Chemicals Standards Committee to provide methods of sampling and test for carbonaceous materials used in the production of aluminium. The standard will be published in two Parts, each Part bein
9、g divided into Sections. The two Parts are: Part 1: Electrode pitch; Part 2: Electrode coke. Initially, it is proposed that Part 2 will comprise the following Sections, applicable to green and/or calcined coke as indicated: Other international methods of test for electrode coke are under considerati
10、on and, subject to approval by the United Kingdom, will be published as they become available. This Section is identical with ISO 6375:1980 “Carbonaceous materials used in the production of aluminium Cokes for electrodes Sampling”, published by the International Organization for Standardization (ISO
11、). Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the followin
12、g. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read as “British Standard”. Cross-references. The Tech
13、nical Committee has reviewed the provisions of ISO 1988:1975, ISO 2309:1980 and ISO 6206:1979, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A related British Standard for ISO 1988:1975 is BS 1017 “Methods for sampling of
14、coal and coke” Part 1:1977 “Sampling of coal”.

The Annex of ISO 2309 is specifically related to Appendices D and E of BS 1017-1:1977 and clause 9 of BS 1017-2:1960 “Sampling of coke”; claus
17、e 4 is specifically related to clause 5 of BS 1017-2:1960 and clause 6 is specifically related to clause 6 of BS 1017-2:1960. A related British Standard for ISO 6206:1979 is BS 1017-2. Additional information. Although the procedures of this Section refer only to calcined cokes, it should be noted th
18、at some of the subsequent Sections will require green coke to be sampled using these procedures. NOTEPrinting error. In the note to 5.2.1 a), line 2, “for” should be read as “of”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards ar
19、e responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

22、ple 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,
23、 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
24、 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
