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).

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 567:1995), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— General and technical revision;

— The container to be used for determination of coke bulk density can either be cubical or cylindrical

in shape with a capacity 0,2 m .

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

Introduction

The bulk density of coke depends on its physical characteristics, e.g. apparent relative density, shape

and size of the coke particles, and on the dimensions of the container. The container specified in this

International Standard has a capacity of 0,2 m . The determination of bulk density of co
