The Contractor shall establish and maintain a Parts Control Program (PCP) with a documented process for the selection and application of parts in development and production of STANDARD Missile systems, subsystems and assemblies. The program shall include provisions for mitigating the impact of parts obsolescence on program integrity. The Contractor's PCP is expected to provide for evaluation down to the component level of the functional performance and reliability of all parts. The Contractor shall assure that part performance, reliability, quality, and safety meet performance requirements for worst case system non-operating and operating environment over the system life cycle. The design process shall assure the use of parts selected from a qualified manufacturing line. Any use of Plastic Encapsulated Devices (PEDs) shall be in accordance with the STANDARD Missile PEDs Guideline, PEO(TAD) ltr 8800 Ser 422-211/225 of 17 Nov 97.
The Contractor's PCP shall be documented and made
available to the Government on request. This program should encourage careful
consideration of the use of equivalent, non-military high reliability parts
and materials in lieu of military specification items. The program should
promote the introduction of new technologies whenever feasible, and promote
stability of the Vendor base, particularly with respect to Diminishing
Manufacturing Sources and Material Shortages (DMSMS), as discussed below.
The PCP shall describe the parts selection process, including all
responsibilities for evaluation, documentation and notification of part
changes, manufacturing process and material changes. This includes the process
for evaluating performance parameters including NH&S.
The process of evaluating new
parts, including nonstandard parts, may include qualification and functional
verification at next higher assemblies. The Parts Control Program shall
include provisions for determination of the need for qualification and/or
proofing, as well as a description of the methods of qualification that may be
utilized by the Contractor, including description of part evaluation
procedures. Parts derating shall be a consideration in the evaluation of new
parts selection and application, as well as parts obsolescence issues.
Guidance for microelectronic and semiconductors testing or test methods can be
obtained from MIL-STD-883 and MIL-STD-750 respectively.
The PCP shall include provisions for flowdown of parts control requirements
to suppliers of assemblies procured by the
