These multi-purpose greases boast a far higher dropping point, generally exceeding 180 °C under GOST 6793.
At the dropping point, the first drop of the sample falls from the test cup.

In modern laboratory facilities, this process is automated using specialized instrumentation like the Lintel Kaplya-20U or similar specialized drop point devices. 🚜 Relevance in Lubricant Manufacturing
Note: While identical in premise, subtle variations in heating rates or cup dimensions between these standards can result in slight numerical differences in the final recorded temperature. These multi-purpose greases boast a far higher dropping
A small grease sample is packed into a specialized metal cup with a standardized hole at the bottom.
The standard outlining the procedure is officially recognized as . Testing typically follows these specific parameters: 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
