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
Complex or polyurea greases intended for extreme operating environments will feature dropping points clearing 230 °C to 250 °C. 🌍 International Equivalents gost 6793
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. This measurement serves as a benchmark for a
These multi-purpose greases boast a far higher dropping point, generally exceeding 180 °C under GOST 6793. Their dropping points typically register on the lower
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?
