The work of preparing Internationai Standards is normaliy 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. 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. International Standard ISO 13310 was prepared by Technical Committee ISo/TC 102, Iron ores, Subcommittee SC 2, Chemical analysis. Together with ISO 13311, it cancels and replaces iSO 8753:1987, of which it constitutes a technical revision. Annex A forms an integral part of this International Standard. Annexes B and C are for information only. C1SO1997 All rights reserved.

This applicability of regulatory limitations prior to use. 1Scope This International Standard specifies a flame atomic absorption spectrometric method for the determination of the zinc content of iron ores. This method is applicable to zinc contents between 0,o01 % (m/m) and 0,5 % (m/m) in natural iron ores, iron ore concentrates and agglomerates, including sinter products. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
