RADC-TR-88-110, TECHNICAL REPORT: RELIABILITY / MAINTAINABILITY / TESTABILITY DESIGN FOR DORMANCY (MAY-1988) [AD-A202-7040]

RADC-TR-88-110, TECHNICAL REPORT: RELIABILITY / MAINTAINABILITY / TESTABILITY DESIGN FOR DORMANCY (MAY-1988) [AD-A202-7040]., his document has been prepared as a tool for designers of dorm~ant military equipment and systems. The purpose of this handbook is to provide design engineers with Reliability/Maintainability/Testability design guidelines for systems which spend significant portions of their life cycle in a dormant state. The dormant state is defined as a nonoperating mode where a system experiences very little or no electrical stress. The guidelines in this report present design criteria in the following categories: (1) Part Selection and Control; (2) Derating Practices; (3) Equiprment/System Packaging; (4) Transportation and Handling; (5) Maintainability Design; (6) Testability Design; (7) Evaluation Methods for In-Plant and Field Evaluation; and (8) Product Performance Agreements. Wherever applicable, design guidelines for operating systems were included with the dormant design guidelines. This was done in an effort to produce design guidelines for a more complete life cycle. Although dormant systems spend significant portions of their life cycle in a nonoperating mode, the designer must design the system for the complete life cycle, including nonoperating as well as operating modes. The guidelines are primarily intended for use in the design of equipment composed of electronic parts avd components. However, they can also be used for the design of systems which encompass both electronic and nonelectronic parts, as well as for the modification of existing systems.
