is the state standard used across Russia and the CIS region to define the test method for determining the dropping point of petroleum products, primarily lubricating greases.

The cup is placed in a test tube alongside a thermometer and steadily heated in a oil or air bath. gost 6793

A small grease sample is packed into a specialized metal cup with a standardized hole at the bottom. is the state standard used across Russia and

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. Lubricating greases are engineered by combining a base

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

At the dropping point, the first drop of the sample falls from the test cup.
