11、ional 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 bee
12、n 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 stand
13、ardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for
14、 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all
15、 such patent rights. ISO 15585 was prepared by Technical Committee ISO/TC 27, Solid mineral fuels, Subcommittee SC 5, Method of analysis.

16、ndex 1 Scope This International Standard specifies a method of determination of caking index of hard coal. It is applicable to the evaluation of caking power of bituminous coal with random reflectance of vitrinite, Rr, greater than 0,6 % and less than or equal to 1,8 % ( 0,6 % u 1,8 %). 2 Normative
17、references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

19、ated at 850 C. 4 Principle A portion of prepared sample of coal of limited size range and the standard anthracite are mixed under defined conditions, and the mixture is carbonized rapidly. The crucible coke thus obtained is tested for strength in a drum conforming to certain specifications. The caki
20、ng power of the test sample is expressed by the abrasive strength, i.e. resistance to breakage of the crucible coke. 5 Reagent 5.1 Standard anthracite, having a moisture of less than 2,5 mass % air-dried basis, an ash of less than 4 mass % dry basis and a volatile matter of less than 8 mass % dry, a
21、sh free basis. The size limits are 0,1 mm to 0,2 mm, the undersize content of 0,1 mm should not be more than 6 mass % and the oversize content of 0,2 mm should not be more than 4 mass %. NOTE Annexes A and B provide information on the extraction, preparation and testing of standard anthracite. BS IS
