ASTM D7097 Thermo-Oxidation Engine Oil Simulation Tester
KN-7097 Thermo-Oxidation Engine Oil Simulation Tester conforms to ASTM D7097 Standard Test Method for Determination of Moderately High Temperature Piston Deposits by Thermo-Oxidation Engine Oil Simulation Test—TEOST MHT and ASTM D6355 Standard Test Method for Determination of High Temperature Deposits by Thermo-Oxidation Engine Oil Simulation Test. Deposit-forming tendencies of an engine oil under oxidative conditions are determined by circulating an oil-catalyst mixture comprising a small sample of the oil and a very small (0.1g) amount of an organo-metallic catalyst. This sample mixture is then circulated for exactly 24h in the TEOST MHT instrument over a special wire-wound depositor rod heated by electrical current to a controlled temperature of 285℃ at the hottest location on the rod. The depositor rod is weighed before and after the test and any deposit formation on the rod as well as any deposits collected from rod washings are determined. During the test, precisely controlled and directed air is caused to bathe the oil flowing down the depositor rod and, thereby, to provide opportunity for oxidation. Precision of the test is strongly influenced by the care in manufacture of the wire-wound steel depositor rods and the treatment of the coating of the wound wire, the rate of air flow, and the amount and degree of mixing of the catalyst.

ASTM D3948 Water Separation Characteristics Of Aviation Turbine Fuels
This tester provides a measure of the presence of surfactants in aviation turbine fuels. it can detect carryover traces of refinery treating residues in fuel as produced. They can also detect surface active substances added to or picked up by the fuel during handling from point of production to point of use. Certain additives can also have an adverse effect on the rating. Some of these substances affect the ability of filter separators to separate free water from the fuel.
