IEC 62961:2018 establishes the measurement of the interfacial tension between insulating liquid and water by means of the Du No°y 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.
