ASTM D892 Foaming Characteristics Of Lubricating Oils
The tendency of oils to foam can be a serious problem in systems such as high-speed gearing, high-volume pumping, and splash lubrication. Inadequate lubrication, cavitation, and overflow loss of lubricant can lead to mechanical failure. This test method is used in the evaluation of oils for such operating conditions.

ASTM D665 Rust Preventing Characteristics Of Inhibited Mineral Oil
A mixture of 300 mL of the oil under test is stirred with 30 mL of distilled water or synthetic sea water, as required, at a temperature of 60 6 1°C (140 6 2°F) with a cylindrical steel test rod completely immersed therein. It is recommended to run the test for 4 h; however, the test period may, at the discretion of the contracting parties, be for a shorter or longer period. The test rod is observed for signs of rusting and, if desired, degree of rusting.

Routine Viscometer
The Cannon-Fenske Opaque Viscometer measures kinematic viscosity of transparent and opaque Newtonian liquids according to ASTM D445, ISO 3104 and ASTM D2170. Minimum sample volume is 12 mL. Minimum bath depth is 230 mm (9 in). Special constant viscometers are available at additional cost. This is a calibrated viscometer which include a certificate of calibration and instruction sheet. Uncalibrated viscometers are also available. Holders are sold separately.

ASTM D1831 Roll Stability Of Lubricating Grease
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.

ASTM D6138 Corrosion Preventive Properties Of Lubricating Greases
New, cleaned, and lubricated bearings are tested partially immersed in water (distilled, synthetic sea water, or sodium chloride solution) under no applied load at a speed of 83 6 5 rpm in a predetermined sequence of running and stopping for a period of approximately one week. After cleaning, the bearing rings are examined and rated according to the degree of corrosion
