Foreword ISO (the International Organi
14、zation 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 establishe
15、d 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.
16、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 t
17、he member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 12977 was prepared by Techn
18、ical Committee ISO/TC 47,Chemistry, Subcommittee SC 7,Aluminium oxide, cryolite, aluminium fluoride, sodium fluoride, carbonaceous materials for the aluminium industry. Annex A of this International Standard is for information only. Licensed Copy: sheffieldun sheffieldun, na, Wed Dec 06 14:47:25 GMT

20、volatile matter content of pitch by gas chromatographic analysis of its solution in toluene. Strict adherence to the procedure is essential because of the empirical nature of the method. 2?Normative references The following normative documents contain provisions which, through reference in this text
21、, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most rece
22、nt 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 Standards. ISO 565,Test sieves Metal wire cloth, perforated metal plate and ele
