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

FTIR Spectrometer for Lubricants
Lubricant oils exhibit various chemical changes during their life time. This starts by simple changes such a fuel dilution of the fuel used or the uptake of soot (ASTM E2412) from the combustion. Numerous chemical reactions with combustion products lead to oxidation (ASTM D7414), nitration (ASTM D7624) or sulfation (ASTM D7415) of the lubricant and can be summarized as degradation products. To enable cycle times known from modern lubricants a wide variety of additives are added. These additives are used up during operation.

ASTM D942 Oxidation Stability Of Lubricating Greases
This apparatus measures the change in pressure resulting from consumption of oxygen by oxidation and gain in pressure due to formation of volatile oxidation by products. It predicts neither the stability of greases under dynamic service conditions, nor the stability of greases stored in containers for long periods, nor the stability of films of greases on bearings and motor parts. It should

ISO 6617 Ageing Characteristics Tester
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.
