10、tional 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 be
11、en 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 stan
12、dardization. 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 fo
13、r 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 al
14、l such patent rights. ISO 17246 was prepared by Technical Committee ISO/TC 27, Solid mineral fuels, Subcommittee SC 5, Methods of analysis. This second edition cancels and replaces the first edition (ISO 17246:2005), of which it constitutes a minor revision. (It also incorporates the Technical corri

16、 the coal industry to provide a basis for comparison of coals. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document
17、 (including any amendments) applies. ISO 562, Hard coal and coke Determination of volatile matter ISO 589, Hard coal Determination of total moisture ISO 1171, Solid mineral fuels Determination of ash ISO 1213-2, Solid mineral fuels Vocabulary Part 2: Terms relating to sampling, testing and analysis
18、ISO 11722, Solid mineral fuels Hard coal Determination of moisture in the general analysis test sample by drying in nitrogen 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 1213-2 apply. 4 Principle Coal is analysed for content of moisture, ash and v
19、olatile matter. The fixed carbon is calculated and the results are reported, to the preferred basis, as a proximate analysis. 5 Preparation of sample Prepare the sample in accordance with the requirements of the various test methods given in Table 1.

21、722 Ash ISO 1171 Volatile matter ISO 562 7 Expression of results The fixed carbon, Cfix,ad, calculated to air-dried basis and expressed as a percentage mass fraction, is given by Equation (1): Cfix,ad= 100 (Mad+ Aad+ Vad) (1) where Madis the moisture in the air-dried sample, expressed as a percentag
22、e mass fraction; Aadis the ash, calculated to an air-dried basis and expressed as a percentage mass fraction; Vadis the volatile matter, calculated to an air-dried basis and expressed as a percentage mass fraction. The result is reported to the nearest 0,1 % mass fraction. The fixed carbon may also
23、be calculated to other bases using the equations in Table 2.
