Abstract

This recommended practice has been developed for use in any EEE system used in the AADHP industries. RPA is especially important to AADHP systems, which are often safety critical applications that must operate for long times in rugged environments. These EEE systems often use EEE components that were originally designed and produced for more benign consumer applications. Although the focus of this recommended practice is on AADHP applications, the process described herein is not limited to AADHP and may be used for EEE systems and components in any industry. Applicability This recommended practice is applicable to all EEE systems, equipment, assemblies, and modules, and the EEE components within them. RPA is useful for evaluating the likelihood of occurrence, and the effects, of failure mechanisms that result from degradation of materials, or accumulated damage that impact the functional outputs of a system. RPA may be applicable to failures caused by design errors, based on the knowledge of the user. Typically, RPA is not applicable to failures caused by quality defects, assembly or installation errors, or misuse of the EEE system, equipment, assembly, module, or components. RPA is not applicable to software. For the most part, RPA is applicable at the electronic assembly, component, or module level, rather than at the system or equipment level. For reliability, durability, and safety assessments, RPA is conducted for the various components or modules of the system or equipment and the results are combined to produce an assessment for the system or equipment1. The same approach is taken for test development; the results are used to define the correct test types, conditions, and durations, as well as whether the tests are conducted at the system, equipment, module, or component levels. For qualification of EEE parts, modules, and sub-assemblies, RPA may be used to compare the item’s capabilities with the qualification requirements, or in support of or to reduce qualification testing.
