Gost 6793 <FRESH × 2026>

Formulated under GOST 1033-79, these are intended for low-temperature applications up to about 65 °C. Their dropping points typically register on the lower end, around 75 °C to 100 °C.

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. gost 6793

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 Formulated under GOST 1033-79, these are intended for

These multi-purpose greases boast a far higher dropping point, generally exceeding 180 °C under GOST 6793. The thickener holds the oil like a sponge

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)

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:

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?
