ASTM D942 Oxidation Stability Of Lubricating Greases
This apparatus measures the change in pressure resulting from consumption of oxygen by oxidation and gain in pressure due to formation of volatile oxidation by products. It predicts neither the stability of greases under dynamic service conditions, nor the stability of greases stored in containers for long periods, nor the stability of films of greases on bearings and motor parts. It should

ASTM D4340 Corrosion Of Cast Aluminum Alloys In Engine Coolants
It is essential that engine coolants prevent heat-transfer corrosion of aluminum cylinder heads during engine operation. Any corrosion products formed may deposit on interior radiator surfaces, reducing heat-transfer efficiency of the radiator. Overheating and boil-over of the cooling system may then occur

ASTM D3612 Dissolved Gases In Transformer Oil By GC TOGA
Transformer oil is a highly refined mineral oil used in electrical transformers. It has excellent insulating properties, suppresses corona and arcing, and serves as a coolant. In case of electrical errors, the oil breaks down to gases, which identity and content can be related to the type and severity of the electrical fault. This information is very useful in the preventative maintenance program.

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 D4693 Low-Temperature Torque Tester
KN-4693 Low-Temperature Torque Tester conforms to ASTM D4693 Standard Test Method for Low-Temperature Torque of Grease-Lubricated Wheel Bearings. This test method covers the determination of the extent to which a test grease retards the rotation of a specially-manufactured, spring-loaded, automotive-type wheel bearing assembly when subjected to low temperatures. Torque values, calculated from restraining-force determinations, are a measure of the viscos resistance of the grease. This test method was developed with greases giving torques of less than 35N·m at 40℃

ASTM D1478 Low-Temperature Torque Tester
KN-1478 Low-Temperature Torque Tester conforms to ASTM D1478 Standard Test Method for Low-Temperature Torque of Ball Bearing Grease. This test method was developed using greases having very low torque characteristics at -54℃. Specifications for greases of this type commonly require testing at this temperature. Specifications for greases of other types can require testing at temperatures from -73℃ to -18℃. This test method has proved helpful in the selection of greases for low-powered mechanisms, such as instrument bearings used in aerospace applications. The suitability of this test method for other applications requiring different greases, speeds, and temperatures should be determined on an individual basis.
