petroleum oil astm d971 surface tension tester measurement tensiometer test machine
ASTM D971 standard test method for interfacial tension
The measurement is made within 60 seconds after forma- tion of the interface with a tensiometer determining tension between 0-100mN/m. The Sigma 702ET ful铿乴ls the requirements of the ASTM D971 standard. The instrument allows the measure- ment do be done fully automatically.

The Surface Tension Test - Is It Worth Resurrecting
Interfacial Tension of Base Oils. Pure water has high surface tension due to its high polarity. Likewise, a pure mineral base oil has a high surface tension due to its high nonpolarity. This can be observed by simply placing a drop of pure base oil (or even turbine oil) on the surface of a glass of water.
ASTM D971-12 Standard Test Method for Interfacial Tension
The TSD 971 performs according to the ASTM D971 Standard Test Method a static measurement under rigidly standardized non-equilibrium conditions of the torque necessary to detach a planar du Nouy ring upward from the surface of water, as well as upward from the water-oil interface.

ASTM D971 standard test method for interfacial tension
In this interfacial tension measurement the platinum ring is lifted through the water-oil interface. The oil is lying on the water surface due to the density difference of these two liquids. Water has a higher surface tension than the oil and therefore force is needed to detach the ring from the water ASTM D971 standard test method for
