Interfacial Tension (ISO 6295)

this test measures the interfacial forces acting between a layer of oil and water. These intermolecular forces are affected by the ageing of the oil. The test result indicates the degree of oxidation and deterioration of oil and possible sludging. These contaminants affect the oil in its ability to perform the functions of cooling, insulating, […]
