9、O (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 co
10、mmittee 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 electro
11、technical 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 me
12、mber 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 identif
13、ying any or all such patent rights. ISO 13930 was prepared by Technical Committee ISO/TC 102, Iron ore and direct reduced iron, Subcommittee SC 3, Physical testing. This second edition cancels and replaces the first edition (ISO 13930:1998), which has been revised to homogenise with other physical t
14、est standards. BS ISO 13930:2007 Licensed Copy: London South Bank University, London South Bank University, Thu Dec 20 03:26:54 GMT+00:00 2007, Uncontrolled Copy, (c) BSI v Introduction This International Standard concerns one of a number of physical test methods that have been developed to measure
15、various physical parameters and to evaluate the behaviour of iron ores, including reducibility, disintegration, crushing strength, apparent density, etc. This method was developed to provide a uniform procedure, validated by collaborative testing, to facilitate comparisons of tests made in different
16、 laboratories. The results of this test should be considered in conjunction with other tests used to evaluate the quality of iron ores as feedstocks for blast furnace processes. This International Standard may be used to provide test results as part of a production quality control system, as a basis
17、 of a contract, or as part of a research project.

This standard does not purpor
19、t to address all of the safety issues associated with its use. 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 Scope This International Standard spec
20、ifies a method to provide a relative measure for evaluating the degree of size degradation of iron ores when reduced under conditions resembling those prevailing in the low-temperature reduction zone of the blast furnace. This International Standard is applicable to lump ores and hot-bonded pellets.
