ASTM D2440 Mineral Insulating Oil Oxidation Stability Test
The oxidation stability test of mineral transformer oils is a method for assessing the amount of sludge and acid products formed in a transformer oil when the oil is tested under prescribed conditions. Good oxidation stability is necessary in order to maximize the service life of the oil by minimizing the formation of sludge and acid.

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 D7153 Automatic Rapid Freezing Point Tester
KN-7153 Automatic Rapid Freezing Point Tester conforms to ASTM D7153 Standard Test Method for Freezing Point of Aviation Fuels (Automatic Laser Method). The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystal which, if present in the fuel system of the aircraft, can restrict the flow of fuel through filters. The temperature of the fuel in the aircraft tank normally decreases during flight depending on aircraft speed, altitude, and flight duration. The freezing point of the fuel shall always be lower than the minimum operational fuel temperature.

ASTM D1275 Transformer Oil Corrosive Sulfur Tester
KN-1275 Transformer Oil Corrosive Sulfur Tester conforms to ASTM D1275 Standard Test Method for Corrosive Sulfur in Electrical Insulating Oils. In most of their uses, insulating oils are continually in contact with metals that are subject to corrosion. The presence of corrosive sulfur compounds will result in deterioration of these metals. The extent of deterioration is dependent upon the quantity and type of corrosive agent and time and temperature factors. Detection of these undesirable impurities, even though not in terms of quantitative values, is a means for recognizing the hazard involved.

ASTM D5800 Evaporation Loss Of Lubricating Oils By The Noack Method
The evaporation loss is of particular importance in engine lubrication. Where high temperatures occur, portions of an oil can evaporate. Evaporation may contribute to oil consumption in an engine and can lead to a change in the properties of an oil. Many engine manufacturers specify a maximum allowable evaporation loss. Some engine manufacturers, when specifying a maximum allowable evaporation loss, quote this test method along with the specifications.

ASTM D2595 Lubricating Grease Wide Temperature Range Evaporation Loss Tester
KN-2595 Lubricating Grease Wide Temperature Range Evaporation Loss Tester conforms to ASTM D2595 Standard Test Method for Evaporation Loss of Lubricating Greases Over Wide-Temperature Range. A weighed sample of grease in an evaporation cell is placed in a heating device maintained at the desired test temperature. Heated air is passed over the grease surface for 22h±0.1h. The loss in weight of the sample due to evaporation is determined.
