Viscous pour point of microquantities of fluid lubricantsA method is described involving the measurement of the viscous desolidification (pour) point of wax-free lubricant fluids. This method is especially useful for pour point testing of experimental quantities, since only six to sixteen drops of the oil are required for a single determination (automatically performed in duplicate) with nearly full recovery of the sample. The technique consists of: (1) rapidly freezing a small, predetermined amount of the oil on the side of a small test tube to form a frozen drop of given dimensions; (2) immersing duplicates of the charged and stoppered tubes into a cold bath; and (3) measuring the temperature when the drop front has moved a predetermined distance as the bath warms up.
