Solid mineral fuels -- Coke -- Determination of moisture in the general analysis test sample

ISO 687:2010 specifies a method for determining the moisture in the general analysis test sample of coke. ISO 687:2010 can be used for the determination of moisture in blast-furnace coke, foundry-coke and other high-temperature carbonization products.

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 687 was prepared by Technical Committee ISO/TC 27, Solid mineral fuels, Subcommittee SC 5, Methods

of analysis.

This third edition cancels and replaces the second edition (ISO 687:2004), of which it constitutes a minor

revision.

Introduction

The determination of the moisture in the general analysis test sample is required to correct the results of

certain analytical determinations, e.g. volatile matter and hydrogen, for the effect of water in the determination

and to allow all determinations to be corrected to a dry basis.

Since coke is hygroscopic, its moisture varies with a change in humidity of the atmosphere, and it is required,

therefore, that the moisture in the general analysis test sample be determined when
