4.4 Acceptance tests.
Acceptance tests shall consist of the individual tests.
4.4.1 Individual tests.
Each adapter shall be subjected to the following
tests as described under 4.6 of this specification.
Examination of product
Conformance to drawings
c. Functional tests
4.4.2 Defects in items already accented. The investigation of a test failure
could indicate that defects may exist in items already accepted. If so, the
contractor shall fully advise the procuring activity of all defects likely to
be found and methods of correcting them.
4.5 Test conditions. Unless otherwise specified, all tests prescribed by this
specification shall be conducted at an atmospheric pressure of 28 to 32 inches
of mercury and at a temperature of 25°C (77°F) + l°C (l°F). Relative humidity
shall be 80 percent or less.
4.5.1 Test power. Unless otherwise specified in specific tests, the testing
power applied shall be 28 volts + l volt direct current (DC).
4.6 Test methods.
4.6.1 Examination of product. Each adapter shall be examined to determine
compliance with the requirements of this specification, including materials,
workmanship, and ease or operation of controls.
4.6.2 Functional tests. Each adapter shall be subjected to the functional
test in accordance with the procedures of 126.96.36.199.
188.8.131.52 Rejection and retest. ln the event an item fails to meet the
appropriate indication requirement of any step of the test, the adapter shall
be rejected, and after correction of cause of failure, shall be resubmitted
for complete functional testing.
184.108.40.206 Preparation for functional tests. Prior to conducting the functional
tests of 4.6.3,the Government loaned AN/GWM-4 must be verified for proper
functioning in accordance with existing acceptance criteria.
220.127.116.11 Functional test procedures.
a. Connect the equipment as shown in Figure 1 with all preliminary switch
settings as shown in Figure 2. Connect the power cable to a direct current
power supply capable of delivery 10 amperes (amps). Connect a set of jumper
wires between the following pins: P2B, P2C, P4-0, P4S, P4U, P4V, P8K, and P8L.
Turn on the power supply. Place the AN/GWM-4 and test adapter power stitches
(S6 and S1, respectively) in the "on" position. The power indicator lights
shall illuminate. The AN/GWM-4 meter, M1, should read 115 ±10 microamperes for
a 28 volt input. Check that the letter "S" (start) appears in the INSULATION
RESISTANCE and CONTINUITY WINDOWS of the AN/GWM-4. If not, override to the
"S" position using the AUTO-SCAN/OVERRIDE switch, S7. Check that the number
"1" appears in the test adapter POSITION window. If not, advance to the
number "1" position using the CIRCUIT ADVANCE switch, S3.
