ASTM D381 Existent Gum Content Tester
KN-381 Existent Gum Content Tester (Steam Method) conforms to ASTM D381 Standard Test Method for Gum Content by Jet Evaporation. When testing either aviation or motor gasoline, a 50±0.5ml quantity of fuel is evaporated under controlled conditions of temperature and flow of air. When testing aviation turbine fuel, a 50±0.5ml quantity of fuel is evaporated under controlled conditions of temperature an flow of steam. For aviation gasoline and aviation turbine fuel, the resulting residue is weighed and reported as milligrams per 100ml. For motor gasoline, the residue is weighed before and after extracting with heptane and the results reported as milligrams per 100ml.

ASTM D94 Saponification Number Of Petroleum Products
A known mass of the sample is dissolved in a suitable solvent, such as butanone (methylethylketone), xylenes, or Stoddard Solvent, or a combination thereof (Warning— Extremely flammable. Vapors can cause flash fire), and is heated with a known amount of alcoholic potassium hydroxide (KOH). The excess alkali is titrated with standard acid, and the saponification number is calculated.

Portable Infrared Spectroscopy Oil Content Detector
KN-EP600 Portable Infrared Spectroscopy Oil Detector will extract oil substances in water with tetrachloroethylene, determine the total extract, then adsorb the extract with magnesium silicate, and determine oil after removing polar substances such as animal and vegetable oils. The contents of total extracts and petroleum are calculated by absorbance a2930, a2960 and a3030 at bands with wave numbers of 2930cm-1 (stretching vibration of C-H bond in CH2 group), 2960cm-1 (stretching vibration of C-H bond in CH3 group) and 3030cm-1 (stretching vibration of C-H bond in aromatic hydrocarbon) respectively. The content of animal and vegetable oil is calculated according to the difference between the total extract and petroleum content

Four Ball Wear Tester
This test method, used for specification purposes, differentiates between lubricating fluids having low, medium, and high level of extreme-pressure properties. The user of this method should determine to his own satisfaction whether results of this test procedure correlate with field performance or other bench test machines.

ASTM D5708 ICP for Crude Oils and Residual Fuels
When fuels are combusted, vanadium present in the fuel can form corrosive compounds. The value of crude oils can be determined, in part, by the concentrations of nickel, vanadium, and iron. Nickel and vanadium, present at trace levels in petroleum fractions, can deactivate catalysts during processing. These test methods provide a means of determining the concentrations of nickel, vanadium, and iron.
