10、ISO 9516-1:2003(E) iv ISO 2003 All rights reserved 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. Eac
11、h 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 Internation
12、al 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 2. The main task of technical committees is to prepare International Standards. Draft International Standard
13、s 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 document may be the subject o
14、f patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 9516-1 was prepared by Technical Committee ISO/TC 102, Iron ore and direct reduced iron, Subcommittee SC 2, Chemical analysis. This first edition, together with ISO 9516-2, cancels and replaces ISO
15、9516:1992 by the augmentation of the range of elements under analysis and the diversification into two procedures. ISO 9516 consists of the following parts, under the general title Iron ores Determination of various elements by X-ray fluorescence spectrometry: Part 1: Comprehensive procedure Part 2:
16、 Simplified procedure ISO 9516-1:2003(E) ISO 2003 All rights reserved v Introduction In this part of ISO 9516, Table 1 indicates that some determinations may be used for referee purposes and others for routine analysis only.

INTERNATIONAL STANDARD ISO 9516-1:2003(E) ISO 2003 All rights reserved 1 Iron ores Determination of various elements by X-ray fluorescence spectrometry Part 1: Comprehensive procedure WARNING This part of ISO 9516 may involve hazardous materials, operations and equipment. This pa
18、rt of ISO 9516 does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this part of ISO 9516 to establish appropriate health and safety practices and determine the applicability of regulatory limitations prior to use. 1 Scope This part
19、of ISO 9516 sets out a wavelength dispersive X-ray fluorescence procedure for the determination of iron, silicon, calcium, manganese, aluminium, titanium, magnesium, phosphorus, sulfur, potassium, tin, vanadium, chromium, cobalt, nickel, copper, zinc, arsenic, lead and barium in iron ores. The metho
20、d has been designed to cope with iron ores having high ignition losses. The method is applicable to iron ores regardless of mineralogical type. The concentration range covered for each of the component elements is given in Table 1. The determination of total iron cannot be used for referee purposes.
