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 D6595 Rotary Disc Electrode Atomic Emission Spectrometer (RDE-AES)
Wear metals and contaminants in a used oil test specimen are evaporated and excited by a controlled arc discharge using the rotating disk technique. The radiant energies of selected analytical lines and one or more references are collected and stored by way of photomultiplier tubes, charge coupled devices or other suitable detectors. A comparison is made of the emitted intensities of the elements in the used oil test specimen against those measured with calibration standards.

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 D2619 Apparatus for Hydrolytic Stability of Hydraulic Fluids
KN-2619 Apparatus for Hydrolytic Stability of Hydraulic Fluids conforms to ASTM D2619 Standard Test Method for Hydrolytic Stability of Hydraulic Fluids (Beverage Bottle Method). This test method differentiates the relative stability of hydraulic fluids in the presence of water under the conditions of the test. Hydrolytically unstable hydraulic fluids form acidic and insoluble contaminants which can cause hydraulic system malfunctions due to corrosion, valve sticking, or change in viscosity of the fluid. The degree of correlation between this test method and service performance has not been fully determined.
