4.6 Test methods and procedures. Unless
otherwise specified
in the contract, the following procedures shall be utilized to
conduct specified tests. If the contractor chooses to use
alternate test procedures, a detailed description of the set-up
and procedure shall be submitted to the government procuring
agency for approval prior to use.
4.6.1 ESS temperature. Testing equipment utilized in the
test shall conform to the requirements of 4.5.2.3.1. The
interconnect shall be placed in the test chamber and the
temperature of the chamber reduced 10C (18F) per minute plus
o
o
or minus l C (1.8 F) from room ambient temperature (as
specified in 3.3.1) to -57C (-71F) . The interconnect shall
be maintained at this temperature for a minimum of 20 minutes.
upon completion of the 20 minute exposure, the temperature of the
o
0
chamber shall be raised 10 C (18 F) per minute plus or minus
1C (1.8F) to +71F (+160C). The interconnect shall
remain at this temperature for a minimum of 20 minutes. Upon
completion of the 20 minute exposure the temperature of the
chamber shall be reduced 10C (18F) per minute plus or minus
1C (1.8F) to room ambient temperature (as specified in
3.3.1). The above procedure shall be conducted a minimum of ten
times. Upon completion of the cycles the interconnect shall then
be removed from the chamber and subjected to the test in 4.6.3.
It shall meet the requirements of 3.2.1.
4.6.2 ESS vibration. Conduct the vibration test with the
interconnect positioned on an appropriate adapter affixed to a
vibrating machine that is capable of providing the amplitudes and
frequencies specified in 3.3.3. Unless otherwise specified, the
test equipment shall be in accordance with the "Test Facilities"
requirements of MIL-F-13926. The applied motion shall be in two
separate planes for the time period specified. Upon completeion of
the vibration sweep the interconnect shall be removed from the
vibration adapter and shall be subjected to the test in 4.6.3. It
shall meet the requirements of 3.2.1.
4.6.3 Functional tests. This test is to be conducted
utilizng a certified Ohm meter. Measure the resistance between
the connector contacts listed in Table II. All measured
resistances shall meet the requirements of 3.2.1.
The interconnect shall be subjected to a
4.6.4 Workmanship.
visual and tactile examination for evidence of faulty
workmanship. The interconnect shall conform to the requirements
of 3.6.
