Improving Traceability in Jet Fuel Testing

Aug 18 2016 Read 870 Times

A well-known and very important quality analysis for Jet Fuel is the Jet Fuel Thermal Oxidation Test, this quality control is performed by the so called JFTOT. Standard working method ASTM D3241 is internationally recognized. When performing a JFTOT analysis according this standard method ensures accurate results. But what are the deviations if the results would be compared to those of another analyser?

European Lab Services (ELS) provides a trustworthy verification of petroleum analysers such as the JFTOT and makes sure each step of the ASTM D3241 is checked thoroughly on a regular basis. The verification program for JFTOT describes calibration of the temperature sensor, verification of the pump speed, verification of the pressure, volume verification, programming of the offsets and eventually run a reference product as final check.

Because of the ISO/IEC 17025 accreditation for this matter, ELS assures you that the instrument performs within the limits of the working method and offers international traceability.

The Intelligent Heater Tube (IHT) improves the traceability of JFTOT analysis. The heater tube is used to determine the so-called JFTOT deposit rating; a visual or elipsometric tube rater measures the deposits on the tube after the JFTOT analysis. Using the new IHT’s with RFID chip makes sure all information of the analysis is stored on the tube; complete data recording of what happened during the analysis is automatically available. Additionally, all transcription errors are eliminated and accidental re-use of the same tube won’t be possible.

For more information about the importance of traceability in petroleum testing, A World First – Verification of Petroleum Analysers According to ISO-Standards’ will give you more insight into this matter.
