Anotation

IEC 62961:2018 establishes the measurement of the interfacial tension between insulating liquid and water by means of the Du Nouy 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. LIEC 62961:2018 specifie le mesurage de la tension interfaciale entre un isolant liquide et leau par la methode a lanneau de Du Nouy proche des conditions dequilibre. Pour obtenir une valeur, qui donne une expression plus realiste de la veritable tension interfaciale, un mesurage apres une maturation de linterface denviron 180 s est enregistre.
