Description

The Jet Fuel Thermal Oxidation Test (JFTOT®) ASTM D3241 is universally used by the industry to measure high temperature stability of aviation turbine fuels. The ASTM D3241 is required to be run on every batch of jet fuel produced according to ASTM D1655 or DEF STAN 91-91 specifications.

In this test method, the fuel is pumped through heater tube at fixed flow rate and during a specified period of time. The fuel is pass or fail rated according to the amount of deposit formed on the heater tube at a specified temperature. Traditionally, the amount of deposit on the tube is rated visually against a reference color scale. The proper rating requires significant experience and expertise. However, operator capabilities vary, so evaluation of color can be quite subjective.

A new instrumental method of quantitative measurement of tube deposits has been developed by
AD Systems, in which the thickness of the deposit is accurately determined by an automatic instrument, reducing test subjectivity. The innovative DR10 instrument uses an interferometry technique (ITR) for precise measurement of deposit thickness in nanometers. This stand-alone compact instrument can be easily installed in any location in minutes. The operation is based on a powerful light source, a spectrometer with fiber optic probe and specially designed application software.
