ActiveLubricating grease--Determination of dropping point
润滑脂滴点测定法
Application Summary AI generated
This standard specifies a test method for determining the dropping point of lubricating greases, which is the temperature at which the grease passes from a semi-solid to a liquid state under defined conditions. It is applied in the petroleum industry for quality control and specification compliance of lubricating greases used in automotive, industrial machinery, and aerospace applications. The test helps assess the high-temperature performance limits of greases, ensuring they maintain structural integrity and lubrication properties under thermal stress.
