LEAKAGE TEST

B-701964-00 Rev. C
This section provides testing information to verify Companion 1000/T performance for
any of the following reasons:
• to determine the cause of operational problems.
• to check the unit's overall system operation after repairing or replacing a compo-
nent.
• to verify the unit is operating within specifications.
To perform the following tests, remove the side covers (Section 5.2.1, Service
and Repair).
The following equipment is required to complete the performance verification tests in
this section:
• Companion Stationary unit containing liquid oxygen saturated at relief valve pres-
sure, 22 psig (152 kPa)
• portable test fixture (Figure 1-12)
• oxygen-compatible liquid leak detector (such as SNOOP)
• test flowmeters capable of accurately registering flows from 0 to 15 L/min (see
Table 1-4)
• calibrated weight scale capable of accurately registering weight from
0 to 10 lb. (0 to 5 kg)
• 7/64-in. Allen (hex key) wrench
• an adjustable, 0 to 50 psig (0 to 345 kPa) source of gaseous oxygen with flexible
3/16-in. I.D. connection tubing
• a test pressure gauge with tubing adapter (Figure 1-13)
Establish a calibration schedule for test equipment used in testing Companion
1000/T units. Follow Calibrating of Test Equipment (Section 1.11) to ensure
accurate test results.
Do not use the test flowmeter, test pressure gauge, or weight scale if they have
been dropped or mishandled; recalibrate before placing them back into
service.
Any amount of liquid oxygen leakage from the Companion 1000/T is unacceptable and
calls for immediate removal from service. Minor gas leaks in connections and fittings
will not affect system operation, provided they do not exceed the unit's NER.
