9、 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
10、 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 Directiv
11、es, 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
12、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 15967 was prepared by Technical Committee ISO/TC 102, Iron ore and direct reduced

14、:26:54 GMT+00:00 2007, Uncontrolled Copy, (c) BSI v Introduction The test method in this International Standard has been developed to evaluate the resistance of direct reduced iron in the form of hot briquetted iron (HBI). The results of this test should be considered in conjunction with other tests
15、 used to evaluate the quality of products of direct reduction processes. This International Standard may be used to provide test results as part of a production quality-control system, as a basis of a contract, or as part of a research project. The level of degradation measured in this test has been
16、 found to be a good indication of HBI resistance during ship loading, transport and handling operations for bulk materials.

It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to its use. 1 S
19、cope This International Standard specifies a method to provide a relative measure for evaluating the resistance of direct reduced iron to size degradation by impact and abrasion. This International Standard specifies the determination of the tumble and abrasion indices of hot briquetted iron (HBI).
