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 D6560 Apparatus for Paraffin, Resins and Asphaltenes Contents in Crude Oil
KN-6560 Apparatus for Paraffin, Resins and Asphaltenes Contents in Crude Oil in Crude Petroleum and Petroleum Products conforms to ASTM D6560 Standard Test Method for Determination of Asphaltenes (Heptane Insolubles) in Crude Petroleum and Petroleum Products and SY/T 7550 Determination of Paraffin, Resins and Asphaltenes Contents in Crude Oil. Asphaltenes are the organic molecules of highest molecular mass and carbon-hydrogen ratio normally occurring in crude petroleum and petroleum products containing residual material. They may give problems during storage and handling if the suspension of asphaltene molecules is disturbed through excess stress or incompatibility.

ASTM D7843 Membrane Patch Colorimetry
KN-7843 Membrane Patch Colorimetry conforms to ASTM D7843 Standard Test Method for Measurement of Lubricant Generated Insoluble Color Bodies in In-Service Turbine Oils using Membrane Patch Colorimetry. Insoluble deposits are extracted from an in-service turbine oil sample using a 47mm, 0.45μm membrane nitrocellulose patch. The color of the patch is then analyzed using a spectrophotometer and the results are reported as a △E value in the CIELAB scale.

ASTM D86 Distillation Of Petroleum Products At Atmospheric Pressure
A 100-mL specimen of the sample is distilled under prescribed conditions for the group in which the sample falls. The distillation is performed in a laboratory batch distillation unit at ambient pressure under conditions that are designed to provide approximately one theoretical plate fractionation. Systematic observations of temperature readings and volumes of condensate are made, depending on the needs of the user of the data. The volume of the residue and the losses are also recorded
