ASTM D6184 Oil Separation from Lubricating Grease (Conical Sieve Method)
The bleeding of oil from grease under static conditions and elevated temperatures is measured. Temperatures from 150°F to 450°F can be used. 30 hours is the usual test period but may be extended or shortened as necessary.
The tendency of oil to separate either during storage or when idle in a hot bearing can be an important property. This test can distinguish between greases that will either promote or prevent oil separation according to the demands of the application.
API Bulletin 5A2 (A.3) substitutes a nickel cone with 1.0 mm holes for the wire screen used in ASTM D6184 and FTM-321.
This technique may simulate oil losses expected through the grease seals typically used on machines and tools used in ‘Lubricated for Life’ bearings.
