Dyestuffs - Determination of solubility in organic solvents - Gravimetric and photometric methods (ISO 7579:2009)

ISO 7579:2009 specifies two methods for determining the solubility of dyestuffs in organic solvents. They are applicable to dyestuffs that do not change chemically under the influence of the solvent and are stable and non-volatile under the specified drying conditions. For volatile solvents (boiling point < 120 °C), the gravimetric procedure is recommended and, for less volatile solvents (boiling point > 120 °C), the photometric procedure is recommended. The choice of procedure should be made on a case-by-case basis.
The methods are suitable for concentrations between 1 g and 1 000 g of dyestuff per litre of solvent. Higher concentrations can be used provided the viscosity of the solution is such that the procedure can be carried out readily.
The methods are not suitable for the determination of insoluble matter in a dyestuff.

Farbstoffe - Bestimmung der Löslichkeit in organischen Lösemitteln - Gravimetrisches und photometrisches Verfahren (ISO 7579:2009)

Diese Internationale Norm legt zwei Verfahren zur Bestimmung der Löslichkeit von Farbstoffen in organischen Lösemitteln fest. Sie sind anwendbar auf Farbstoffe, die sich chemisch unter dem Einfluss des Lösemittels nicht verändern und unter den festgelegten Trocknungsbedingungen beständig und nicht flüchtig sind. Für niedrigsiedende Lösemittel ( 120 °C) wird ein gravimetrisches und für hochsiedende Lösemittel ( 120 °C) ein photometrisches Verfahren empfohlen. Die jeweilige Auswahl sollte problemspezifisch getroffen werden.
Die Verfahren sind vornehmlich für Konzentrationen zwischen 1 g und 1000 g Farbstoff je Liter Lösemittel geeignet. In Fällen höherer Konzentrationen muss die Prüflösung für die beschriebenen Verfahren geeignet sein.
Die Verfahren sind nicht für die Bestimmung unlöslicher Anteile in einem Farbstoff geeignet.

Colorants - Détermination de la solubilité dans les solvants organiques - Méthodes gravimétrique et photométrique (ISO 7579:2009)

L'ISO 7579:2009 spécifie deux méthodes de détermination de la solubilité des colorants dans les solvants organiques. Ces méthodes s'appliquent aux colorants qui ne changent pas chimiquement sous l'influence du solvant et qui sont stables et non volatils dans les conditions prescrites de séchage. La méthode gravimétrique est recommandée pour les solvants volatils (point d'ébullition inférieur à 120 °C), la méthode photométrique étant recommandée pour les solvants moins volatils (point d'ébullition supérieur à 120 °C). Le choix de la méthode appropriée se fait au cas par cas.
Ces méthodes conviennent pour des concentrations comprises entre 1 g et 1 000 g de colorant par litre de solvant. Des concentrations supérieures peuvent être utilisées pour autant que la viscosité des solutions d'essai soit telle que la méthode puisse être suivie telle quelle.
Les méthodes ne conviennent pas pour la détermination des matières insolubles dans un colorant.
