Surface active agents - Determination of interfacial tension of solutions of surface active agents by the stirrup or ring method

This European Standard specifies test methods for the determination of interfacial tension in the range from 4 mN/m to 50 mN/m between two immiscible liquids which can also be free from surface active agents.
It is particularly suitable for determining the interfacial tension between water or aqueous solutions and organic liquids which are immiscible with water.

Grenzflächenaktive Stoffe - Bestimmung der Grenzflächenspannung von grenzflächenaktiven Lösungen mittels Bügel- oder Ringverfahren

Anwendungsbereich
Diese Europäische Norm legt Verfahren zur Messung der Grenzflächenspannung im Bereich von 4 mN/m bis 50 mN/m zwischen zwei nicht mischbaren Flüssigkeiten, die auch frei von grenzflächenaktiven Stoffen sein können, fest.
Die Messverfahren eignen sich insbesondere zur Bestimmung der Grenzflächenspannung zwischen Wasser oder wässrigen Lösungen und organischen Flüssigkeiten, die mit Wasser nicht mischbar sind.

Agents de surface - Détermination de la tension interfaciale des solution d'agents de surface par la méthode à l'anneau ou l'étrier

Domaine d'application
La présente Norme européenne spécifie des méthodes d'essai pour la détermination de la tension interfaciale dans le domaine de 4 mN/m à 50 mN/m entre deux liquides non miscibles qui peuvent également être exempts d'agents de surface.

=g(1)3 Apparatus3.1 Tensiometer3.1.1GeneralThe tensiometer shall be designed for use with a stirrup or ring and shall consist essentially of the parts specifiedin 3.1.2 and 3.1.3.3.1.2Dynamometer (e.g. torsion balance or inductive force transducer), capable for reading off the force to thenearest 0,1 mN/m over the effective length of the stirrup or ring.3.1.3Support for the measuring vessel, consisting of a horizontal platform which can be moved vertically upand down, e.g. with the aid of a precision drive.3.2 StirrupThe stirrup shall consist of platinum/iridium wire with a test wire diameter of 0,1 mm and a length of 20 mmto 40 mm. The length of the two branches shall be about 20 mm. Two small platinum balls can be attached to thelower ends of the branches as counterweights or, alternatively, the lower ends of the branches can be joined by aplatinum wire (see Figure 1 as an example).
