MIL-DTL-9320E
d. Operating voltage (see 4.5.4).
4.4.2 Sampling tests. Unless otherwise specified (see 6.2), sampling shall be in accordance
with verification level I of MIL-STD-1916.
4.4.2.1 Lot. A lot shall consist of warning signals manufactured under essentially the
same conditions and submitted for inspection at the same time.
4.4.2.2 Tests. The warning signal shall be subjected to:
a.
Individual tests (see 4.5.1).
b.
Internal impedance (see 4.5.5).
c.
Reliability (see 4.5.8).
d.
Vibration (limit test to room temperature) (see 4.5.9).
e.
Shock (see 4.5.10).
f.
High temperature (see 4.5.13).
4.5 Test methods.
4.5.1 Examination of product. The warning signal shall be inspected to determine
compliance with the requirements specified herein with respect to material, design and
construction, workmanship, dimensions, weight, and identification of product.
4.5.2 Dielectric strength. The warning signal shall be subjected to 600 V RMS for
60 seconds. The voltage shall be applied simultaneously between all terminals of the connector
and the case. The warning signal dielectric strength shall meet the requirements specified in
3.4.3. At the conclusion of this test, there shall be no evidence of failure and the warning signal
shall operate satisfactorily.
4.5.3 Current consumption. The output pins of the warning signal shall be connected to a
150-ohm load and the current measured. The warning signal current shall be as specified in 3.4.4.
This test shall be performed separately on each output pin.
4.5.4 Operating voltage. The warning signal shall be monitored with an oscilloscope to
determine its operation from a 14 to 29 V DC source. Frequency, dB level, and interruption rate
shall be monitored when the warning signal is loaded as specified in 3.4.2.2. The warning signal
operating voltage shall be as specified in 3.4.5.
4.5.5 Internal impedance. The impedance between pin A and each output pin shall be
measured with pin A connected to 28 V DC positive, pin B disconnected, and an ammeter
connected between the output terminal and the ground. A DC microammeter shall be used and
the maximum current shall not exceed 2.8 microamperes. The current between pin B and pin C,
with the unit not energized, shall be measured with 28 V DC applied to pin B and an ammeter
connected between pin C and ground. This current shall be less than 1.0 mA.
