ASTM D1177 Automatic Freezing Point Of Aqueous Engine Coolants
This tester involves the determination of the time-temperature curve prior to freezing and the determination of the horizontal or flattened portion of the freezing curve. The freezing point is taken as the intersection of projections of the cooling curve and the freezing curve. If the solution supercools, the freezing point is the maximum temperature reached after super cooling

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.

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 D8288 Automatic Tapping Torque Testing System
KN-8288 Automatic Tapping Torque Testing System conforms to ASTM D8288 Standard Test Method for Comparison of Metal working Fluids Using a Tapping Torque Test Machine. This test method can be used to predict the comparative lubricating properties of a metalworking fluid (MWF). Fluids that produce lower torques or higher efficiencies are predicted to have better machining characteristics. The method is applicable to all tap types, machining speeds, alloys and coatings that can be fabricated into a test piece. Comparison between different operating conditions or various types of fluids can be made. The reportable quantity is the efficiency or mean average torque of a reference fluid divided by the mean average torque of the fluid of interest.

ASTM D2386 Automatic Freezing Point Of Aviation Fuel
The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystals that can restrict the flow of fuel through filters if present in the fuel system of the aircraft. The temperature of the fuel in the aircraft tank normally falls during flight depending on aircraft speed, altitude, and flight duration. The freezing point of the fuel must always be lower than the minimum operational tank temperature
