6.2
Test Values:
Normal and limiting values
of performance data shall be deter-
mined at input voltages of
27.5 0.5 V DC and 115 1.0 V AC as
applicable. These data are
to be used in testing the equipment
at installation points for
compliance with minimum acceptable
standard of perfomance.
6.3
Performance Objectives:
Minimum size and weight, simplicity of operation, ease of main-
tenance, and an improvement in the performance and reliability
of the specific functions beyond the requirements of this spe-
cification are objective which shall be considered in the
production of this equipment. Where it appears a substantial
reduction in size and weight or improvement in simplicity of
design, performance, ease of maintenance of reliability will
result from the use of materials, parts and processes other
than those specified, it is desired their use be investigated.
When investigation shows advantages can be realized, a request
for approval shall be submitted to the procuring activity for
consideration. Each request shall be accompanied by complete
supporting information.
As a general rule non-repairable subassemblies should be encap-
6.4
sulated or hermetically-sealed. The number of connections
internal to the subassembly should be held to a minimum. Detail
parts tolerances and ratings should be so selected that the life
of the subassembly is greater than that of a similar repairable
one. With few exceptions (such as high voltage power supplies),
the non-repairable subassembly should evidence a Mean-time-to-
failure greater than 5000 hours, and for any applications this
figure must be nearer 50,000 hours.
6.5
Precedence of Documents:
When the requirements of the contract, this specification, or
applicable subsidiary specifications are in conflict, the follow-
ing precedence shall apply:
(1) Contract - The contract shall have precedence over any spe-
cification.
