FOREWORD
IS0 (the International Organization for Standardization) is a worldwide federation
of national standards institutes (IS0 Member Bodies). The work of developing
International Standards is carried out through IS0 Technical Committee. 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 IS0 Council.
International Standard IS0 3703 was drawn up by Technical Committee
ISO/TC 47, Chemistry, and was circulated to the Member Bodies in January 1975.
It has been approved by the Member Bodies of the following countries :
Belgium Ireland South Africa, Rep. of
Brazil Israel Spain
France Italy Switzerland
Germany Poland Turkey
Hungary Portugal United Kingdom
India Romania Yugoslavia
No Member Body expressed disapproval of the document.

adhering to acid-grade fluorspa5he method is applicable
to materials which have been subjected to a flotation
process and which have flotation agent contents equal to or
5.3 Mechanical stirrer, powered by an electric motor and
greater than 0,002 % (m/m) of the dried material.
fitted with a 40 mm diameter paddle.
