Surface active agents - Determination of physical stability in alkaline and acid solutions

This European Standard specifies a method for the determination of physical stability of surface active agents in alkaline and acid solutions. It is applicable to all classes of surface active agents and also to other substances or mixtures such as polymers, complexing agents and formulations of surface active agents.

Grenzflächenaktive Stoffe - Bestimmung der physikalischen Stabilität in alkalischer und saurer Lösung

Diese Europäische Norm legt ein Verfahren zur Bestimmung der physikalischen Stabilität von grenzflächen-
aktiven Stoffen in alkalischer und saurer Lösung fest. Das Verfahren gilt für alle Klassen von grenzflächenak-
tiven Stoffen, aber auch für andere Stoffe oder Mischungen wie Polymere, Komplexiermittel und Formulierun-
gen von grenzflächenaktiven Stoffen.

Agents de surface - Détermination de la stabilité physique dans les solutions alcalines et acides

La présente Norme européenne spécifie une méthode de détermination de la stabilité physique des agents de surface dans les solutions alcalines et acides. Elle est applicable à toutes les classes d'agents de surface ainsi qu'à d'autres substances ou mélanges tels que les polymères, les agents complexants et les formulations d'agents de surface.
