Insulating liquids. Test methods for the determination of interfacial tension of insulating liquids. Determination with the ring methodWhat is this standard about? This document establishes the measurement of the interfacial tension between insulating liquid and water by means of the Du Noy ring method close to equilibrium conditions. In order to obtain a value that provides a realistic expression of the real interfacial tension, a measurement after a surface age of approximately 180 s is recorded.
