This Military Standard provides equipment designers and
manufacturers with a list of electronic parts having quality levels
most acceptable in the design and construction of Mi 1itary systems
and equipments. It also will aid to control and minimize the life
cycle cost, improve reliability of equipment and minimize logistic
support. The criteria used in selecting parts are as follows:
1. APPlication need. Parts requiring reliable parts.
2. Technological maturity. and must use proven materials
and for a period sufficient to ensure have been identified and
adequate must satisfy the widest range of design The design of the
part must be final technologies. It must have been in production
that the design and process parameters quality controls have been
3. Availability. The part must be in production by at
least one manufacturer whose previous performance indicates ability
to qualify to specifications of this standard. There must also be
reasonable expectation that the part wi11 not be obsolescent for at
least seven years. Microcircuits are excluded from this requirement
because of rapid technological changes.
4. Test or usaqe history. Sufficient test or usage data
to predict part reliability must be available.
In the event of conflict between the technical description of
standard parts in this standard and the applicable specification,
the specification shall govern.
Technical information included in this standard was obtained
from military specifications and standards; no warranty is made of
data accuracy, or that inclusion of these parts wi 11 assure
equipment/systems will meet performance requirements of any
contracts. The contractor is responsible for conducting necessary
tests and inspections of selected parts to assure that contract
requirements are met.
