equipment. Where it appears a substantial reduction in size and
weight or improvement in simplicity of design, performance, ease
of maintenance or reliability will result from the use of
materials, parts and processes other than those specified in

When investigation shows advantages can be realized, a request for
approval shall be submitted to the procuring activity for

Non-Repairable Subassemblies - As a general
rule non-repairable subassemblies should be encapsulated 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 many applications this figure
must be nearer 50,000 hours.

Type Designations - The parentheses (*), when
used
in
the
