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 non­governmental, 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 of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 27, Coal and coke, Subcommittee SC 3,

Coke.

This third edition cancels and replaces the second edition (ISO 1014:1985), which has been technically

revised. It also incorporates the Technical Corrigendum ISO 1014:1985/Cor 1:1994.

The main changes compared to the previous edition are as follows:
— the normative references (see Clause 2) have been updated;

— the mandatory Terms and definitions clause (Clause 3) has been added and subsequent clauses have

been renumbered;
— general and technical revision.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.

Coke — Determination of true relative density, apparent
relative density and porosity
1 Scope
This document specifies methods for

a) determining the true relative density of coke, crushed to <212 µm, in relation to water;

NOTE “True relative density” varies according to the displacement liquid used.

b) determining the apparent relative density of coke, i.e. the ratio of the mass of a volume of dry coke

to the mass of an equal volume of water;
c) calculating the porosity of the coke.

4 True relative density
4.1 Principle

The mass of water displaced by a known mass of dry coke, ground to pass a sieve of nominal size

of openings 212 µm, is determined using a pyknometer. Air is displaced by boiling during the

determination. Air-free distilled water is specified. Thermostatic control of the temperature is essential

since a difference of 1 °C can cause an error of about 0,012 in the result.
4.2 Apparatus

ISO/FDIS 1014:2021(E)

4.2.2 Water bath, with stirrer, thermostatically controlled to maintain a desired temperature 0 °C to

within ±1 °C.

4.2.3 Two wash bottles, each containing about 50 ml of air free distilled water. One wash bottle is

kept hot (80 °C to 90 °C) and the other is left in the water bath (4.2.2).

4.2.4 Reflux air condenser: a glass tube about 1 m long, of the same external diameter as the neck of

the pyknometer (4.2.1) with a short length of rubber tubing for attaching it to the latter.

4.2.5 Glycerol bath: a suitable vessel in which sufficient glycerol can be heated for the lower two-

thirds of the pyknometer (4.2.1) to be immersed.
