DESCRIPTION
BS EN IEC 62961:2018
This standard BS EN IEC 62961:2018 Insulating liquids. Test methods for the determination of interfacial tension of insulating liquids. Determination with the ring method is classified in these ICS categories:
- 29.040.10 Insulating oils
This document 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.
