Standard Test Method for Interfacial Tension of Insulating Liquids Against Water by the Ring Method

Importancia y uso:

4.1 Interfacial tension measurements on electrical insulating liquids provide a sensitive means of detecting small amounts of soluble polar contaminants and products of oxidation. A high value for new mineral insulating oil indicates the absence of most undesirable polar contaminants. The test is frequently applied to service-aged mineral oils as an indication of the degree of deterioration.

Note 1: Different liquid matrixes are reviewed in Appendix X1.
