We perform lubricating grease quality testing by ASTM D5969 to determine the corrosion-preventive properties of greases. ASTM D5969 uses grease-lubricated tapered roller bearings exposed to various concentrations of dilute synthetic sea water and stored under wet conditions. This test is based on ASTM D1743, which uses distilled water and a similar procedure. The test result is a pass or fail rating determined by at least two of three bearings.
Sample quantity required: 400 ml
