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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

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. Details of any

patent rights identified during the development of the document will be in the Introduction and/or on

the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the meaning of ISO specific terms and expressions related to conformity

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

to Trade (TBT), see the following URL: Foreword — Supplementary Information.

INTERNATIONAL STANDARD ISO 602:2015(E)
Coal — Determination of mineral matter
1 Scope

This International Standard specifies a method of determining the amount of mineral matter in all types

of coal, including brown coals and lignites.
2 Normative references
There are no normative references cited in this document.
3 Principle
The following principle applies:

a) partial demineralization of a sample of the coal by treatment with hydrochloric and hydrofluoric

acids under such conditions that the coal substance remains unaffected;

b) recording of the loss in mass of the coal due to the acid treatment and determination of the

undissolved part of the mineral matter by ashing the partially demineralized coal;

c) determination of the iron content of the ash so that the pyrites present in the extracted coal can be

calculated; and

d) determination of the amount of hydrochloric acid absorbed by the coal substance.

4 Reagents

During the analysis, use only reagents of recognized analytical grade and only distilled water or water

of equivalent purity.
4.1 Hydrochloric acid, ρ 1,18 g/ml.
4.2 Hydrochloric acid, solution, c(HCI) 5 mol/l.
4.3 Hydrofluoric acid, ρ 1,13 g/ml.

WARNING — Very toxic by inhalation, in contact with skin, and if swallowed. Causes severe burns.

Keep container tightly closed in a well-ventilated place. In case of contact with eyes, rinse

immediately with plenty of water and seek medical advice.

Wear suitable protective clothing and gloves. In case of accident or feeling unwell, seek medical

advice immediately (show the label where possible).
5 Apparatus

All the apparatus listed below shall be resistant to acids, especially hydrofluoric acid. A suitable material

is polyvinyl chloride (PVC).
5.1 Beaker, of capacity 200 ml, with a cover slip.
