General methods of test for pigments and extenders - Part 21: Comparison of heat stability of pigments using a stoving medium (ISO 787-21:1979)
The method is intended for comparing the heat stability by specifying the temperatures of heating and the time of heating; it may also be used for determining the heat resistance of a pigment. The comparison of heat stability is carried out against that of an agreed sample.
Allgemeine Prüfverfahren für Pigmente und Füllstoffe — Teil 21: Vergleich der Hitzebeständigkeit von Pigmenten unter Verwendung eines Einbrennbindemittels (ISO 787-21:1979)
Dieser Teil von ISO 787 legt ein allgemeines Prüfverfahren zum Vergleichen der Hitzebeständigkeit des zu prüfenden Pigmentes mit der einer vereinbarten Probe fest.
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 ist, sollte ein spezielles Verfahren zum Vergleich der Hitzebeständigkeit festgelegt werden.
Méthodes générales d'essai des pigments et matières de charge - Partie 21: Comparaison de la stabilité à la chaleur des pigments en utilisant un liant au four (ISO 787-21:1979)
Splošne metode preskušanja pigmentov in polnil - 21. del: Primerjava toplotne obstojnosti pigmentov z uporabo toplotnega medija (ISO 787-21:1979)
Metoda je namenjena za primerjavo toplotne obstojnosti z določitvijo temperatur ogrevanja in časa ogrevanja. Lahko se uporablja tudi za določanje toplotne odpornosti pigmenta. Primerjava toplotne obstojnosti se izvede s primerjavo z dogovorjenim vzorcem.
