MIL-P-48606B(AR)
3.2 Components and assemblies.  The components and assemblies
shall comply with all requirements specified on Drawing 11748133,
all associated drawings, and with all requirements specified in
applicable specifications and standards.  Where applicable, the
power supply assembly shall meet the requirements of MIL-F-13926 as
follows:
a.
Dimensions and tolerances.
b.
Inorganic protective surface finishings.
c.
Part identification and marking.
d.
Workmanship.
3.3 Environmental service conditions.
3.3.1 Vibration.  The power supply assembly shall not suffer
damage and shall meet the requirements of 3.4 and 3.5 after exposure
to sinusoidal vibrations, in each of three mutually perpendicular
axes, as follows:
Frequency Range
Amplitude
10 to 15 hertz
0.06 inches double amplitude
15 to 25 hertz
0.04 inches double amplitude
25 to 55 hertz
0.02 inches double amplitude
The
frequency of vibration shall be swept logarithmically.
The
cycling time shall be 120 minutes per axis.
sweep rate shall be 3.75 minutes + 10% per decade.
The
The
10-55-10 hertz sweep time is 3 minutes 45 seconds + 10%.
3.3.2 Altitude.
3.3.2.1 Operating.  The power supply assembly shall meet the
requirements of 3.4 and 3.5 during and after exposure to barometric
pressure encountered at 10,000 feet above sea level (20.6 inches of
Hg).
3.3.2.2 Non-operating.  The power supply assembly shall meet
the requirements of 3.4 and 3.5 after exposure for not less than 10
minutes to barometric pressure encountered at 40,000 feet above sea
level (5.5 inches of Hg).
3.3.3 Temperature.
3.3.3.1 0perating
The power supply assembly shall meet the
requirements of  3.4 and 3.5 when stabilized thermally at any
temperature between -40 degrees F and +155 degrees F.
3.3.3.2 Non-operating (storage).  The power supply assembly
shall not suffer permanent damage when subjected to the constant
temperature extremes of -60 degrees F for a period of 24 hours and
+160 degrees F for a period of 4 hours (after temperature
stabilization ), and shall meet the requirements of 3.4 and 3.5 when
returned to room ambient.
