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.
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
Complex or polyurea greases intended for extreme operating environments will feature dropping points clearing 230 °C to 250 °C. 🌍 International Equivalents Formulated under GOST 1033-79, these are intended for
Technicians monitor the cup. The exact temperature recorded on the thermometer when the first drop falls through the bottom hole is officially cataloged as the dropping point. Complex or polyurea greases intended for extreme operating
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 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?
