Fuel sample containers used for
sediment and water tests must be
made of what construction?
1.
Glass with a metal top
2.
A nonmetallic material with
glass linings
3.
Glass with a nonmetallic top
4.
Metal with glass linings
Which of the following is NOT a
requirement for the identification
of a sample?
1.
The location and name of the
activity submitting the sample
2.
The location of the point where
the sample was taken
3.
The sample classification
4.
Test results
A representative sampling of a
large stock of packaged fuel
revealed contamination sufficient
to make the entire supply suspect.
Further samples are taken, labeled,
and sent to be tested.
What were
the first and subsequent samples
taken?
1.
A composite sample, and the
others were routine samples
2.
A routine sample, and the
others were special samples
3.
A routine sample, and the
others were composite samples
4.
A special sample, and the
others were routine samples
When visually inspecting a fuel
sample, What should be the first
thing you check?
1.
The color of the fuel sample
2.
The aroma of the fuel sample
3.
The presence of water
4.
The presence of sediment
2-25.
How should you visually check a
fuel sample for sediment?
1.
Shake it vigorously to break
loose any previously undetected
emulsion
2.
Whirl it rapidly so the fine
particles will be thrown to the
outside of the sample container
3.
Place the sample container on a
level surface and allow the
sediment to collect on the
sides of the container
4.
Swirl it to form a vortex that
will draw the sediment to the
center-bottom of the container
2-26.
If contamination is found in a fuel
sample, another sample should be
drawn in a new, clean container and
the visual inspection repeated.
1.
True
2.
False

The contaminated fuel detector
(CFD/CCFD) employs which of the
following principles?
1.
2.
3.
4.
Trapped solid contaminants
increase the amount of light
passing through the millipore
filters
Trapped solid contaminants
decrease the amount of light
passing through the millipore
filters
Solid contaminants increase the
weight of the top millipore
filter more than the color
variation increases the weight
of the bottom one
The weight of the solid
contaminants trapped between
the millipore filters is equal
to the amount of solid
contaminants in the sample
