with input fitting of tuner #3.
3. Standard test connector with hermaphroditic output fitting compatible with input fitting of tuner #3
and input interface compatible without output interface of adapter to be tested.
4. Standard test connector of opposite sex to item 3 and hermaphroditic input fitting compatible with
output fitting of the slotted line.
5. Adapter under test.

4.5.12 Durability (see 3.15). Each adapter under test shall be mated with a typical production
connector in accordance with this specification. The adapter shall be subjected to the number of
cycles of mating and unmating specified (see 3.1). The adapter and its mating part shall be
completely engaged and completely disengaged during this cycle. Lubrication of the threads or
rotational parts shall not be employed for this test unless specified (see 3.1). It is permissible to
shake or blow debris from the threads or interface surfaces at intervals of not less than 50 cycles.
Solvents or tools shall not be used for cleaning.
of MIL-STD-202. The following details shall apply:
a. Special preparations or conditions.
(1) The maximum relative humidity shall be 50 percent. When facilities are not
available at this test condition, adapters are tested at room ambient relative
humidity. In case of dispute, if the test has been made at room ambient
relative humidity, retest shall be made at 50 percent maximum relative
humidity.
(2) Precautions shall be taken to prevent air-gap voltage breakdowns.
(3) The voltage shall be metered on the high side of the transformer.
b. Magnitude of test voltage (see 3.1): The voltage shall be instantaneously applied.
c.
Nature of potential: Alternating current.
d. Points of application of test voltage: Between the center contact and body.
4.5.14 Contact resistance (see 3.17). The contact resistance of the mated outer contacts and the
contact resistance of the mated inner contacts shall be measured, as applicable, as specified herein.
The coupling mechanism shall be removed when measuring contact resistance of the outer contacts.
The test set-up shall be as shown on figure 6. The test shall be performed as follows:
