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 15967 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 tumble strength of HBI. The test gives a
relative measure of the resistance of HBI to size degradation by impact and abrasion, following the same principle
as the tumble test for iron ores (see ISO 3271). The level of degradation measured in the test has been found to be
similar to that experienced by HBI during ship loading, transport and bulk materials handling operations.
