Scope

This document describes the methods of the liquid-film pull-up method, drop weight method, maximum bubble pressure method, and hanging drop method as methods for measuring the static surface tension of surfactants and water or organic solutions containing one or more surfactant mixtures. This document is suitable for measuring the static surface tension of surfactant and detergent solutions, and is also suitable for measuring the static surface tension of pure liquids or solutions other than the above-mentioned solutions.
