ASTM D36 Softening Point Of Bitumen
Two horizontal disks of bitumen, cast in shouldered brass rings, are heated at a controlled rate in a liquid bath while each supports a steel ball. The softening point is reported as the mean of the temperatures at which the two disks soften enough to allow each ball, enveloped in bitumen, to fall a distance of 25 mm (1.0 in.)

ASTM D6082 High Temperature Foaming Characteristics Of Lubricating Oils
The tendency of oils to foam at high temperature can be a serious problem in systems such as high-speed gearing, high volume pumping, and splash lubrication. Foaming can cause inadequate lubrication, cavitation, and loss of lubricant due to overflow, and these events can lead to mechanical failure

ASTM D1945 Analysis Of Natural Gas By GC
This GC is of significance for providing data for calculating physical properties of the sample, such as heating value and relative density, or for monitoring the concentrations of one or more of the components in a mixture.

ASTM D4291 Trace Ethylene Glycol In Used Engine Oil By GC
Leakage of aqueous engine coolant into the crank case weakens the ability of the oil to lubricate. If ethylene glycol is present, it promotes varnish and deposit formation. This test method is designed for early detection to prevent coolant from accumulating and seriously damaging the engine

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.

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

ASTM D1263 Leakage Tendencies Of Automotive Wheel Bearing Greases
The test method provides a screening device that permits differentiation among products having distinctly different leakage characteristics. It is not the equivalent oflongtime service tests, nor is it intended to distinguish between wheel bearing greases showing similar or borderline leakage
