General methods of test for pigments and extenders - Part 22: Comparison of resistance to bleeding of pigments (ISO 787-22:1980)

Specifies a method for comparing the resistance to bleeding with that of an agreed sample. The method has been established because it is essentially a practical test and as such is probably of greater general value than other methods.

Allgemeine Prüfverfahren für Pigmente und Füllstoffe - Teil 22: Vergleich der Beständigkeit von Pigmenten gegen Ausbluten (ISO 787-22:1980)

Dieser Teil von ISO 787 legt ein allgemeines Prüfverfahren zum Vergleichen der Beständigkeit eines Pigmentes gegen Ausbluten mit der einer vereinbarten Probe.
ANMERKUNG   Wenn dieses allgemeine Verfahren auf ein gegebenes Pigment anwendbar ist, sollte die internationale Norm, die sich mit diesem Pigment befasst, nur einen Querverweis zu diesem Verfahren beinhalten, zusammen mit detaillierten Anmerkungen zu Modifikationen, die in Anbetracht der besonderen Eigenschaften des Pigmentes erforderlich sein könnten. Nur wenn dieses allgemeine Verfahren auf ein bestimmtes Pigment nicht anwendbar sind, sollte ein spezielles Verfahren zum Vergleich der Beständigkeit gegen Ausbluten festgelegt werden.

Méthodes générales d'essai des pigments et matières de charge - Partie 22: Comparaison de la résistance au saignement des pigments (ISO 787-22:1980)

Donne des indications sur les limites de température maximales de court-circuit des câbles électriques de tension assignées de 1kV (Um = 1,3 kV) et 3 kV (Um = 3,6 kV), en ce qui concerne:
- les matériaux d'isolation;
- les matériaux de gainage et de bourrage;
- les matériaux de l'âme et de la gaine métallique et les méthodes de raccordement.
La conception des accessoires et l'influence des conditions d'installation sur les limites de température sont prises en compte.

Splošne metode preskušanja pigmentov in polnil - 22. del: Primerjava odpornosti pigmentov proti bledenju (ISO 787-22:1980)

Ta standard določa metodo za primerjavo odpornosti pigmentov proti bledenju z dogovorjenim vzorcem. Ta metoda je bila določena, ker gre v bistvu za praktični preskus, in ima kot taka verjetno večjo splošno vrednost kot druge metode.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO member bodies). The werk of developing Interna-
tional 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 787/22 was developed by Technical Committee
ISO/TC 35, Paints and varnishes, and was circulated to the member bodies in
March 1978.
lt has been approved by the member bodies of the following countries :
Australia Ireland Romania

The purpose of this International Standard is to establish a series of general test
methods for Pigments and extenders which are suitable for all or many of the individual
Pigments and extenders for which specifications might be required. In such cases, a
Cross-reference to the general method should be included in the International Standard
relating to that Pigment or extender, with a note of any detailed modifications which
might be needed in view of the special properties of the product in question.
Technical Committee ISO/TC 35 decided that all the general methods should be
published as they become available, as Parts of a Single International Standard, in Order
to emphasize the relationship of each to the whole series.
