ASTM D1831 ROLL STABILITY OF LUBRICATING GREASE
This test method covers determination of the changes in the consistency, as measured by cone penetration, of lubricating greases when worked in the roll stability test apparatus.
ASTM D7342 SHEAR STABILITY OF LUBRICATING GREASE IN PRESENCE OF WATER
This test method covers two procedures for determining the shear stability of lubricating grease in the presence of water (wet shear stability) by a full scale grease worker or a roll stability test apparatus. Both procedures can be used to determine the relative wet shear stability of greases, but the results between procedures are not directly comparable. This test method is also known as the water stability test.
