Abstract
A thermal oxidation tester is shown for determining thermal stability of a fluid, particularly hydrocarbons, when subjected to elevated temperatures. The tendency of the heated fluid to oxidize and (1) form deposits on a surface of a heater tube and (2) form solids therein which are both measured at a given flow rate, temperature and time. The measured results are used to determine whether a fluid sample passes or fails the test. Specifically constructed containers used in a thermal oxidation tester are shown. These containers (1) reduce physical contact to hydrocarbon test fuels, (2) reduce exposure to hydrocarbon fuel vapors, (3) reduce environmental impact by reducing chemical spills, and (4) improve overall work flow of test.
