MIL-PRF-29504/5D
a.
MIL-S-901. Mated connector assemblies shall be tested in accordance with MIL-S-901, grade
A, type B, class I. Standard shock fixture 4A for bulkhead mounting shall be used. Supplement
test fixture with mounting shall be performed as specified in NAVSEA Drawing 8283255."
b.
Half-sine pulse. Mated connector assemblies shall be tested in accordance with TIA-455-14,
test condition D. Three shocks in each direction shall be applied along the three mutually
perpendicular axes of the test sample (18 shocks).
Vibration. Mated connector assemblies shall be tested for sinusoidal vibration in accordance with
the applicable vibration tests listed below. Optical discontinuities shall be measured during the test.
For connectors of shell sizes 17 and greater, a minimum of four termini shall be monitored for
discontinuity. The change in optical transmittance shall be monitored after the test. The termini
shall be visually examined after the test to the extent feasible inside the connector. Termini shall not
be damaged, and there shall be no loosening of parts, no backing off of the coupling mechanism,
and no other damage which can produce physical distortion or wear and may result in fatigue of the
mechanical parts. The requirement for optical discontinuity shall be met during the test and the
requirement for the change in optical transmittance shall be met after the test. For testing, initially
mate the connector assemblies and apply the specified torque value. Mark the position after the
torque has been applied and check/record position after each axis. For a mating connector
containing a coupling ring ratchet mechanism, do not tighten the coupling ring during testing.
Sine vibration in accordance with 4.5.22.2.1 of MIL-DTL-38999 (60 G at ambient temperature
only). This cycle shall be performed 12 times in each of three mutually perpendicular directions
at ambient temperature. This results in a total of 36 cycles being applied for approximately 12
hours. The sequence shall be repeated twice. (36 hours total at ambient temperature).
Interruptions are permitted provided the requirements for rate of change and test duration are
met. Completion of cycling within any separate band is permissible before proceeding to the next
band.
Random vibration in accordance with 4.5.22.2.3 of MIL-DTL-38999 (41.7 G rms at temperature of
125oC).
Random vibration in accordance with 4.5.22.2.4 of MIL-DTL-38999 (49.5 G rms at ambient
temperature)
Environmental. The following environmental tests shall be performed in the sequence listed: Thermal
shock and temperature life.
Thermal shock. The temperatures of -55oC +0°C, -5°C and +165oC +5°C, -0°C shall be used for the
low and high soak temperatures, respectively. Mated connector assemblies shall be tested in
accordance with TIA/EIA-455-71, schedule C-0 (5 cycles). The mated connector assemblies shall
not be un-mated then re-mated after the test as part of the inspection. The change in optical
transmittance shall be measured during (towards the end of each soak temperature) and after the
test. The termini shall be visually examined after the test only if optical performance is not met.
Termini shall not be damaged, and there shall be no loosening of parts, separation of bonded
surfaces or other damage detrimental to the operation of the termini. The requirement for the
change in optical transmittance shall be met during and after the test.
