When reading a technical data sheet (TDS) for an industrial or automotive grease manufactured under GOST standards, you will almost always see GOST 6793 cited next to the dropping point specification. For instance:

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.

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?
