Fuels & Lubricants Testing Capabilities

ASTM D971 (Interfacial Tension – Oil Against Water by DuNuoy Tensiometer)

April 24, 2024

We perform lubricants testing by ASTM D971 to measure the interfacial tension between mineral oil and water. Interfacial tension measurements on electrical insulating oils 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 contaminants. The test is frequently applied to service-aged oils as an indication of the degree of deterioration. 

Contact us today to receive a quote for your mineral oil testing.
