IEC 62961:2018通过接近平衡条件的杜努伊环法确定了绝缘液体和水之间界面张力的测量。为了获得真实界面张力的真实表达式，记录约180 s表面老化后的测量值。

IEC 62961:2018 establishes the measurement of the interfacial tension between insulating liquid and water by means of the Du Noüy 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.
