Foreword
ISO (the International 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 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 closely 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 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 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 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 corrigendum ISO 17246:2005/Cor.1:2006.)

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 (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
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 volatile 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.
