MIL-PRF-49164C(CR)
3.6.2 High temperature. Damage or performance degradation shall not occur by storage
to +95°C or continuous operation to +71°C. The postamplifier shall operate for 30 minutes at
+95°C.
3.6.3 Low temperature. The postamplifier shall not be damaged nor shall the
performance be degraded by operation to -54°C or storage to -62°C.
3.6.4 Shock. Damage or degradation of specified performance shall not occur by high
intensity shocks of 100 g's peak amplitude with 11 milliseconds duration and by bench handling
tests.
3.6.5 Vibration. Damage or degradation of performance shall not occur when the
postamplifier is subjected to vibration over the frequency spectrum at the specified "g" levels
and amplitudes shown in Figure 1.
3.7 Reliability. The postamplifier shall have a mean time between failure (MTBF) of at
least 18,000 hours, θo.
3.8 Preconditioning. Each postamplifier shall be subjected to at least a 20-cycle
preconditioning environment as specified in Figure 2 prior to Group A inspection (For exception
to this requirement see 6.2.f).
3.9 Soldering. Unless otherwise specified, soldering shall be in accordance with
ANSI/IPC-S-815A.
3.10 Nameplates and product marking. The postamplifier shall be marked with the part
number "80063-SM-D-773889" and the manufacturer's CAGE code number. MIL-HDBK-454
may be used for guidance in marking.
3.11 Workmanship. All electronic parts, components, assemblies or sub-assemblies shall
be free of smudges, excess solder, metal chips or the existence of any foreign material on any
surface. Bearing assemblies shall be free from rust, dirt or tool marks. Wires and integrated
circuitry shall be protected from contact with rough or irregular surfaces and be shielded from
shorting.
