Hardmetals - Determination of contents of metallic elements by X-ray fluorescence - Solution method (ISO 4883:1978)
The solution method determines cobalt, iron, manganese, molybdenum, nickel, niobium, tantalum, titanium, tungsten, vanadium and zirconium. Is applicable to carbides of niobium, tantalum, titanium, vanadium, tungsten and zirconium, mixtures of these carbides and binder metals, all grades of presintered or sintered hardmetals, produce from these carbides, with the minimum element contents shown in table 1.

FOREWORD
ISO (the International Organization for Standardization) is a worldwide federation
of national Standards institutes (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 set
up 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 4883 was developed by Technical Committee
ISO/TC 119, Powder metallurgical materials and products, and was circulated
to the member bodies in December 1977.
lt has been approved by the member bodies of the following countries :
Germany South Africa, Rep. of
Australia
Austria I reland Spain
Bulgaria I taly Sweden
Canada Japan Turkey
Chile Korea, Rep. of United Kingdom
Mexico U.S.A
Czechoslovakia
Poland U.S.S. R
Egypt, Arab Rep. of
Romania
France
No member body expressed disapproval of the document.
