Transition of MIL-STD-785 From a Military to a Physics-of-Failure Based Com-Military Document

The MIL-STD-785, ôReliability Program for Systems and Equipment, Development
and Production,?is the basic reference document for the general requirements
of reliability programs for the defense industry. The document is
used by the defense industries in the selection and implementation of various
reliability tasks required for the design and manufacture of electronic
equipment. These tasks span the acquisition process through the development,
production and initial deployment stages. The standard that sets
guidelines for selecting and tailoring the specific tasks required to meet
the needs of a reliability program for defense equipment manufacture.
The manufacturer may propose to tailor these tasks to suit the particular
needs of the equipment being developed depending on the type, magnitude
and funding of the project. However, such modifications require prior
approval by the DoD and must be supported by a proper rationale.
This paper addresses modification to the MIL-STD-785, which will incorporate
the extensive physics-of-failure based reliability prediction methods now
available. The transition from the present to the physics-of-failure
based approach involves the complete restructuring of MIL-STD-785 in several
key areas which include: reliability prediction, modeling, maintainability,
logistics, FMECA, EPCTA, parts programs, ESS, RDGT, RQT, PRAT FRACAS and
accelerated reliability testing. The paper highlights the advantages
gained to both commercial as well as defense related industries by the
implementation of the modified MIL-STD-785 as a COM-MILITARY standard.
