Dropping Point


OELCHECK Test equipment:	Automatic test instrument for dropping point Mettler Toledo FP83HT, FP90
Sample quantity needed:	2 gram
Unit:	°C
Operating time	About 1,5 hours
Test result:	Temperature, when grease becomes liquid by destroying the thickener.
Analysis of:	Lubricating grease
Brief description:	The dropping point is the temperature when grease becomes liquid by destroying the thickener. That means a drop from the liquid grease is falling through an opening to the bottom of a test pipe.
Statement:	The dropping point is mainly used for the quality control of the grease producer. It`s importance for operation temperature limit of the grease is low. There is no reliable formula available that can be used to calculate the upper usage temperature limit of the grease on the basis of the dropping point temperature.
