Technicians monitor the cup. The exact temperature recorded on the thermometer when the first drop falls through the bottom hole is officially cataloged as the dropping point.
The dropping point is a critical physical indicator in tribology (the study of friction and wear). It indicates the specific temperature at which a grease passes from a semi-solid to a liquid state under controlled conditions. 🔍 What is the Dropping Point? gost 6793
The standard outlining the procedure is officially recognized as . Testing typically follows these specific parameters: Technicians monitor the cup
Lubricating greases are engineered by combining a base oil with a thickener and performance additives. The thickener holds the oil like a sponge. As grease is heated, it reaches a temperature where the thickener can no longer retain the oil. It indicates the specific temperature at which a
This measurement serves as a benchmark for a lubricant’s heat resistance, defining the maximum temperature it can endure before losing its structural integrity. ⚙️ How the GOST 6793 Test Works
At the dropping point, the first drop of the sample falls from the test cup.
A small grease sample is packed into a specialized metal cup with a standardized hole at the bottom.
