The work of preparing International Standards is normally carried out through IS
13、O 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 c
14、losely 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 circulat
15、ed 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 12985 may be the subject of patent rights. ISO shall not be held re
16、sponsible for identifying any or all such patent rights. International Standard ISO 12985-1 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 12985 consists

19、luminium Baked anodes and cathode blocks Part 1: Determination of apparent density using a dimensions method 1?Scope This part of ISO 12985 specifies a dimensions method for the determination of the apparent density of carbonaceous products used in the production of aluminium. This method is applica
20、ble to samples with a simple or well-defined geometry (cylindrical, rectangular parallelepipedical, cubic, etc.) and having a smooth surface profile. The accuracy of measurement is strongly influenced by the equipment used for sampling, i.e. the drilling and sawing machines. 2?Normative references T
21、he following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 12985. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of IS
22、O 12985 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
