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: At the dropping point, the first drop of

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.

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.

If you are working with equipment or grease specified under non-CIS metrics, the procedure outlined in GOST 6793 is highly comparable to the following international standards: or ASTM D2265 (United States) ISO 2176 (International Organization for Standardization) DIN 51801 (Germany)
