Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of developing International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been authorized 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO 7627/3 was developed by Technical Committee ISO/TC 119, Powder rnetallurgy, and was circulated to the member bodies in August 1982. lt has been approved by the member bodies of the following countries: Austria Germany, F.R. grazil Italy Bulgaria Korea, Rep. of China Norway Czechoslovakia Poland Egypt, Arab Rep. of Romania France South Africa, Rep. of Spain Sweden Switzerland United Kingdom USA USSR No member body expressed disapproval of the document. 0 International Orgahization for Standardkation, 1983 Printed in Switzerland SIST EN 27627-3:2000



INTERNATIONAL STANDARD ISO 7627/3-1983 (E) Hardmetals - Chemical analysis by flame atomic absorption spectrometry - Part 3: Determination of Cobalt, iron, nianganese and nicke1 in contents from 0,Ol to 0,5 % (mlm) 1 Scope and field of application This part of ISO 7627 specifies the method to be used for the determination of Cobalt, iron, manganese and nicke1 contents of hardmetals within the range 0,Ol to 0,5 % (mlm) by flame atomic absorption spectrometry. General requirements concerning the field of application, prin- ciple, interfering elements, apparatus, sampling and test report are given in ISO 7627/1. 4.2 Dissolution of the test Portion Add 10 ml of water, 5 ml of the hydrofluoric acid (3.1). and then 5 ml of the nitric acid (3.21, drop by drop, to the beaker containing the test Portion (4.1) and heat gently until the test Portion is completely dissolved. Add 10 ml of the caesium chloride Solution (3.4) and 10 ml of the ammonium fluoride Solution (3.3). Then transfer the Solution totally to a 100 ml polypropylene one-mark volumetric flask and dilute to the mark. 2 Reference 4.3 Dilution volume ISO 762711, Hardmetals - Chemical analysis b y flame atomic absorp tion spectrometry - Part 7 : General requiremen ts.
