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

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 D924 Dielectric Dissipation Factor Tester
Dissipation Factor (or Power Factor)—This is a measure of the dielectric losses in an electrical insulating liquid when used in an alternating electric field and of the energy dissipated as heat. A low dissipation factor or power factor indicates low ac dielectric losses. Dissipation factor or power factor may be useful as a means of quality control, and as an indication of changes in quality resulting from contamination and deterioration in service or as a result of handling.

ASTM D2809 Apparatus for Cavitation Corrosion and Erosion-Corrosion Characteristics
KN-2809 Apparatus for Cavitation Corrosion and Erosion-Corrosion Characteristics conforms to ASTM D2809 Standard Test Method for Cavitation Corrosion and Erosion-Corrosion Characteristics of Aluminum Pumps with Engine Coolants. This test method can be used to distinguish between coolants that contribute to cavitation corrosion and erosion-corrosion of aluminum automotive water pumps and those that do not. It is not intended that a particular rating number, as determined from this test, will be equivalent to a certain number of miles in a vehicle test; however, limited correlation between bench and field service tests has been observed with single-phase coolants. Field tests under severe operating conditions should be conducted as the final test if the actual effect of the coolant on cavitation corrosion and erosion-corrosion is to be appraised. It is also possible, with proper control of the test variables, to determine the effect of pump design, materials of construction, and pump operating conditions on cavitation corrosion and erosion-corrosion damage.

ASTM D2570 Simulated Service Corrosion Tester
KN-2570 Simulated Service Corrosion Tester conforms to ASTM D2570 Standard Test Method for Simulated Service Corrosion Testing of Engine Coolants. An engine coolant is circulated for 1064h at 88℃ (190℉) in a flow loop consisting of a metal reservoir, an automotive coolant pump, an automotive radiator, and the connecting rubber hoses. Test specimens representative of engine cooling system metals are mounted inside the reservoir, which simulates an engine cylinder block. At the end of the test period, the corrosion-inhibiting properties of the coolant are determined by measuring the mass losses of the test specimens and by visual examination of the interior surfaces of the components.

ASTM D1287 PH Meter
KN-1287 PH Meter conforms to ASTM D1287 Standard Test Method for pH of Engine Coolants and Antirusts and ASTM D1121 Standard Test Method for Reserve Alkalinity of Engine Coolants and Antirusts. pH is a measure of the hydrogen ion concentration and indicates whether an engine coolant, or a solution of these compounds is acidic, alkaline, or neutral. The pH range includes values from 0 to 14. Values from 0 to 7 represent the acidic half of the scale. Values from 7 to 14 represent the alkaline or b
