Hardmetals - Chemical analysis by flame atomic absorption spectrometry - Part 1: General requirements (ISO 7627-1:1983)

Subsequent parts of ISO 7627 specify methods for determination of the content of a number of elements (see the table). The method is applicable to cabides of chromium, niobium, tantalum, titanium, tungsten, vanadium, mixtures of these carbides and binder metals, all grades of presintered or sintered hardmetals, produced from these cabides, and coated hardmetals, after total removal of coating, with the elements shown in the table.

Métaux-durs - Analyse chimique par spectrométrie d'absorption atomique dans la flamme - Partie 1: Caractéristiques générales (ISO 7627-1:1983)

La présente partie de l'ISO 7627 établit les caractéristiques générales pour l'analyse chimique des métaux-durs par spectrométrie d'absorption atomique dans la flamme. Les parties suivantes de la présente Norme internationale (voir le tableau) spécifient des méthodes de dosage par spectrométrie d'absorption atomique dans la flamme des éléments suivants :
calcium
cobalt
chrome
fer
potassium
magnésium
manganèse
molybdène
sodium
nickel
titane
vanadium
Cette méthode est applicable :
a) aux carbures de chrome, niobium, tantale, titane, tungstène, vanadium,
b) aux mélanges de ces carbures et des métaux liants,
c) aux métaux-durs de toutes nuances, préfrittés ou frittés,
  obtenus à partir de ces carbures,
d) aux métaux-durs revêtus, après élimination totale
  du revêtement, contenant les éléments indiqués dans
  le tableau.
NOTE -- La méthode de dosage du chrome permet également le dosage
du fer, du nickel, du cobalt et du manganèse dans la gamme des teneurs
comprises entre 0,01 et 2 % (m/m).

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 patt 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 7627/1 was developed by Technical Committee ISO/TC 119, Powder metahrgy, 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. Brazil 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 Organkation for Standardkation, 1983 Printed in Switzerland SIST EN 27627-1:2000
