MIL-HDBK-1547, DEPARTMENT OF DEFENSE HANDBOOK: ELECTRONIC PARTS, MATERIALS, AND PROCESSES FOR SPACE AND LAUNCH VEHICLES (09 NOV 1997) [SUPERSEDING MIL-STD-1547]., This Handbook was developed to aid Designers and Parts, Materials, and Processes (PMP) specialists with the design, development, and fabrication of electronic systems required to have long life and/or high reliability while operating under extreme conditions/ environments of Space and Launch Vehicles. The purpose of this handbook is to establish and maintain consistent and uniform methods for development of technical requirements for electronic parts, materials, and processes used in the design, development, and fabrication of space and launch vehicles. It provides a common basis for estimating of Application Information, Design and Construction Considerations, and Quality Assurance Provisions for the proposed Design Application. It also establishes a common basis for comparing and evaluating of industry practices for related or competitive designs. This handbook is intended to be used as a tool to increase the performance and reliability of the system under design.
