12、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
13、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 Directive
14、s, 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 c
15、asting 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 11535 was prepared by Technical Committee ISO/TC 102, Iron ore and direct reduced
16、iron, Subcommittee SC 2, Chemical analysis. This second edition cancels and replaces the first edition (ISO 11535:1998), which has been technically revised. It has been updated to alter the manner in which the precision data are presented. BS ISO 11535:2006Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA
