Allgemeine Prüfverfahren für Pigmente und Füllstoffe - Teil 8: Bestimmung der wasserlöslichen Anteile - Kaltextraktionsverfahren (ISO 787-8:1979)
1.1 Teil 8 dieser Internationalen Norm legt ein allgemeines Prüfverfahren zur Bestimmung des Massenanteils in % von in kaltem Wasser löslichen Anteilen einer Pigment- oder Füllstoffprobe fest. 1.2 Teil 3 dieser Internationalen Norm legt ein Verfahren zur Bestimmung des Massenanteils in % von in Wasser löslichen Anteilen durch Heißextraktion fest. Diese beiden Verfahren führen bei den meisten Pigmenten und Füllstoffen zu unterschiedlichen Ergebnissen. Es ist deshalb wichtig, daß zu einer Anforderung angegeben wird, welches Verfahrenanzuwenden ist und im Prüfbericht, welches Verfahren angewendet wurde.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards institutes (IS0 member bodies). The work of developing Interna-
tional Standards is carried out through IS0 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 IS0 Council.
International Standard IS0 787/8 was developed by Technical Committee ISO/TC 35,
Paints and varnishes, and was circulated to the member bodies in November 1977.
It has been approved by the member bodies of the following countries :
Australia Israel Romania
South Africa, Rep. of
Brazil Italy
Canada Kenya Spain
Egypt, Arab Rep. of Mexico Sweden
Netherlands Switzerland
France
Germany, F. R. New Zealand Turkey
United Kingdom
India Norway
Peru USSR
Iran
Ireland Poland
No member body expressed disapproval of the document.
This International Standard cancels and replaces IS0 Recommendation R 787/8-1970
of which it constitutes a technical revision.
