Benefits
The current visual rating method used for
specificationpurposessuffersfromthedrawbackof
operator subjectivity and provides no real
information on the thickness and volume of
deposits, parameters which are far more
meaningfulforcharacterizingjetfuelsforusersand
suppliers.
TheDR10measuresthedepositthicknessat1,200
pointsaroundthesurfaceofthetube.Attheendof
thetest,itdisplaysa3Dmappingofthedepositin
addition to average and maximum thicknesses and
totalvolumedeposit.
Applications
TheDR10isdesignedforalltypesofapplicationsrelated
to thermal oxidation testing of jet fuels including
research, refining, pipeline, terminals, and mobile
laboratory applications every location where thermal
oxidationofjetfuelisevaluated.
Principle
TheDR10usesaninterferometrytechniquebasedon
a powerful light source, a fiber optic probe, and a
spectrometer.Specificlightisemittedonthesurfaceof

The DR 10 is equipped with a touch screen. A virtual
alphanumerickeypadisusedtoprogramthetest.The
sample types, the operator names and test
temperaturesarepreprogrammed.OnlythesampleID
and the tube serial number have to be entered. The
tube serial number is displayed by a camera and the
techniciansimplyentersthedisplayedserialnumberat
the beginning of the test. With this minimal data
entry, the 1,200 points tube scanning is initiated. The
fulltubescaniscompletedinlessthan15minutes.
TheDR10displaysa3Dimageofthedepositandthe
average and the maximum thickness deposit values.
The mean deposit thickness of the thickest 2.5 mm2
area defined in the ASTM D 3241 is reported in
additiontothecalculatedtotaldepositvolume.
