Test Kit for Captured Fuel
TM 5 6630 217-10
Testing
Visually inspect the test kit for damage or leaks. Determine that all components
are present that fluids in chambers 1 & 3 are at the same level, that orifices are
clear and that the density Indicator (float) is intact If the test kit is damaged,
discard the damaged kit as no provision for maintenance exists; If not, proceed
with the test.
The first test accomplished by looking though the test sample In chamber #4 at
the grid lines, if the lines are not visible, the fluid being tested In not acceptable
and the testing of the sample is terminated.
Filing and Draining
The test kit is equipped with two ports for filling. The ports are large enough to
allow filling by pouring from a container. One port allows tilling of the specific
gravity/visual contamination module. This port is fitted with a barrier to prevent
removal or loss d the density indicator from the test chamber. The second port
allows filling the viscosity module test chamber and has a stainless steel screen
installed within the port, which has a sieve size sufficient to retain particles
equal to or greater than the smallest clearance in the viscosity tubes. Both
ports are fitted with attached "snap caps" that allow the sample filled tester to be
Inverted without danger d spilling the samples. Both test chambers are filled to
the appropriate levels and allowed to sit until test kit and test fuel are at
approximately the same temperature. Fill time for both chambers including
opening the ports, filling chambers and closing the ports can be accomplished
In less than one minute. Draining both chambers la done simultaneously by
pouring and shaking the tester. 95 to 98% of total sample fluids may be poured
from tester within two minutes, including opening ports, draining and closing
ports.
Specific Gravity Measurements
Specific gravity measurement is by means of an indicating densimeter. This
densimeter is in the form of a "float". There are two possible readings.
Acceptable or "GO" when the Indicator floats. Rejected or "NOGO" when the
indicator sinks. The indicator is designed to float in test samples with a specific
gravity d 0.78 (at 25 degrees Celsius) or higher; this is an acceptable or "GO"
fuel. The indicator is designed to sink in a fuel with specific gravity of less than
0.78 (at 25 degrees Celsius).
