标准摘要
[中文适用范围]： 本文件规定了对绝缘液体与水之间的界面张力进行测量的方法，使用杜努伊环法（Du Noüy ring method），并接近平衡条件。为了获得能真实反映实际界面张力的数值，在界面形成约180秒后进行记录测量。 [外文原描述]： 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.
