The CMC-PC is designed and constructed in accordance with the general requirements of MIL-STD-454.
The cooling of the components on the CMC-PC cards is accomplished by conduction. The cooling of the CMC-PC Power Supply and the Pentium chip are accomplished by circulated air and by conduction through the aluminum enclosure of the unit which is built as an
External connectors are used for
interfacing with the subassemblies or equipment and are in accordance with
requirement of MIL-STD-454. Connector mating bodies are keyed, and
keyed locations are varied to prevent improper installation.
Identification and Marking
The marking and labels of the equipment meet
the requirements of MIL-M-13231.
Moisture & Fungus Resistance
CMC-PC assemblies are moisture
resistant and are not nutrients for fungi. The PC Cards are treated
with Conformal coating for protection. The coating conforms to MIL-I-46058C.
The computer external surfaces
are chemically treated prior to painting. All residues and contaminants are removed
prior to applying one coat of primer. The finish is semi-gloss per
treatments (welding, soldering, brazing and corrosion

the corrosive effects of salt fog environment. The CMC-PC meets the requirements specified in
MIL-STD-810E Method 509.3
Procedure I. The base metal shall not be visible through the finish or coating, nor shall
be any evidence of blistering, softening, separation from the base metal,
corrosion products, or other coating failure.
The CMC-PC is qualified
according to MIL-STD-810F for airborne, ground and Naval environment.
The CMC-PC operates as
specified herein after being subjected to operational shock as encountered on board (airborne, naval) or
transport. Testing according to MIL-STD 810E, 40 g for duration of 11msec.
The CMC-PC, in an operating or
non operating condition, shall not be affected by humidity for both
continuous and intermittent periods, including conditions wherein
condensation takes place in and on the equipment in the form of
water. The CMC-PC meets the requirements specified in MIL-STD-810E.

The CMC-PC as specified
with its PCI BUS, its internal boards, and the computer’s components, disks and power supplies complies
of MIL-STD-461C as follows:
CE03 - Electromagnetic emissions do
not appear on 60Hz AC leads in excess of values shown in MIL-STD-461C,
RE02 - Electromagnetic emissions are
not radiated from the CMC-PC equipment
in excess of values shown in MIL-STD-461C, Fig 4-14, 4-15.
RS03 - The CMC-PC does not exhibit any permanent degradation of performance or any
deviation from its
specifications when subjected to radiated electrical of 1
Volts/meter from 14KHz to 10GHz.
CS02 - The CMC-PC does not exhibit any permanent degradation of performance or any deviation from its
specifications when subjected to 100 Volt from a 50 ohm source
to its AC power leads
components of the CMC-PC are physically and functionally interchangeable in accordance with MIL-STD-454. Parts or
components of the same part
number procured to this specification are physically and functionally
interchangeable without selection, adjustment or fit.
Maintainability and Modularization
CMC-PC is designed such that it is completely maintainable by replacement
use is made of plug in module assemblies.
CMC-PC -PC has an MTBF of 10,000 hours at 25°C . Mean Time To Repair
(MTTR) does not exceed 30 minutes. The MTTR includes the time required to
detect and isolate the failure, replace the failed unit, checkout the
repair and return the system to full operational status.
