ASTM D1831 Roll Stability Of Lubricating Grease
Brand KN
Product origin Dalian,China
Delivery time deliver as soon as received payment
Supply capacity 30 sets one month
The roll stability test is widely used in specifications. Test results are significant insofar as they can show a directional change in consistency that could occur in service. No accurate correlation is established between the test resultsand shear stability in actual service.
KN-1831 Roll stability Apparatus for Lubricating Grease
Overview
KN-1831 Roll stability Apparatus for Lubricating Grease conforms to ASTM D1831 Standard Test Method for Roll Stability of Lubricating Grease. Cone penetration of an approximately 50-g aliquot of lubricating grease is determined. The grease is then subjected to low shear at 20 to 35°C(68 to 95°F) for 2h±5min in a standard roll stability apparatus, before the cone penetration is a gain measured. The difference between the cone penetration before working and the cone penetration after is used as a measure of the effect to flow shear working on grease consistency. This apparatus is suitable to test the consistence change of the lubricating grease after working on the roller tester to judge the mechanical shear stability of the lubricating grease.
