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.
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. 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
The cup is placed in a test tube alongside a thermometer and steadily heated in a oil or air bath. The cup is placed in a test tube
At the dropping point, the first drop of the sample falls from the test cup.
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?
