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 3.

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 International Standard may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 15968 was prepared by Technical Committee ISO/TC 102, Iron ore and direct reduced

iron, Subcommittee SC 5, Physical testing of direct reduction feedstock and DRI.
Annexes A and B form a normative part of this International Standard.

Introduction

The international trade of hot briquetted iron (HBI) as a merchant commodity is increasing rapidly and is expected

to grow beyond 10 million tonnes per annum in the twenty-first century. This has led to the need for the

development of test method standards for HBI.

This International Standard specifies a method for the determination of the apparent density of HBI. The test gives

a measurement of apparent density which is useful as a test of briquetting machine performance, as a measure of

briquette quality, and may be used as part of a programme to certify that HBI meets the requirements of the

International Maritime Organization (IMO) Code of Safe Practice for Solid Bulk Cargoes.

CAUTION – This International Standard may involve hazardous materials, operations and equipment. This

International Standard does not purport to address all of the safety problems associated with its use. It is

the responsibility of the user of this International Standard to establish appropriate safety and health

practices and to determine the applicability of regulatory limitations prior to use.
