General methods of test for pigments and extenders - Part 14: Determination of resistivity of aqueous extract (ISO 787-14:2002)
This part of ISO 787 specifies general methods of test for determining the water-soluble sulfates (gravimetric method) and chlorides (titrimetric method using silver nitrate) in pigments and extenders.
Allgemeine Prüfverfahren für Pigmente und Füllstoffe - Teil 14: Bestimmung des spezifischen Widerstandes des wässrigen Extraktes (ISO 787-14:2002)
Dieser Teil von ISO 787 legt ein allgemeines Prüfverfahren zur Bestimmung des spezifischen Widerstandes eines wässrigen Pigmentextraktes fest.
Das Verfahren ist für alle Pigmente und Füllstoffe anwendbar, außer für Pigmente, die wesentlich in Wasser löslich sind.
Es ist darauf hinzuweisen, dass der spezifische Widerstand eines wässrigen Pigmentextraktes als eine von der Menge des wasserlöslichen Materials unabhängige Eigenschaft angesehen werden sollte. Falls vereinbart, kann ein Kaltextraktionsverfahren angewendet werden. Dies ist im Prüfbericht anzugeben.
Die Normtemperatur kann zwischen den beteiligten Parteien vereinbart werden, vorausgesetzt, dass die notwendigen Korrekturen berücksichtigt werden, um der unterschiedlichen Temperatur Rechnung zu tragen.
ANMERKUNG Wenn dieses allgemeine Verfahren für ein gegebenes Pigment anwendbar ist, braucht nur ein Querverweis in die Internationale Norm für dieses Pigment aufgenommen zu werden mit einem Hinweis auf jede einzelne Abweichung, die im Hinblick auf die besonderen Eigenschaften des betreffenden Pigmentes notwendig ist. Nur wenn dieses allgemeine Verfahren für ein bestimmtes Pigment nicht anwendbar ist, sollte ein spezielles Verfahren für die Bestimmung des spezifischen Widerstandes festgelegt werden.
Méthodes générales d'essai des pigments et matieres de charge - Partie 14: Détermination de la résistivité de l'extrait aqueux (ISO 787-14:2002)
La présente partie de l'ISO 787 spécifie une méthode générale d'essai pour déterminer la résistivité (résistance spécifique) de l'extrait aqueux d'un pigment. La méthode est applicable à tous les pigments et matières de charge, à l'exception des pigments très solubles dans l'eau.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established 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. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 787 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO787-14 was prepared by Technical Committee ISO/TC35, Paints and varnishes,
Subcommittee SC 2, Pigments and extenders.
This second edition cancels and replaces the first edition (ISO 787-14:1973), of which it constitutes a minor
(editorial) revision.
