This part of IEC 61163 provides guidance on RSS techniques and procedures for electrical, electronic, and mechanical components. This document is procedural in nature and is not, and cannot be, exhaustive with respect to component technologies due to the rapid rate of developments in the component industry.

This document is:

  1. intended for component manufacturers as a guideline;

  2. intended for component users as a guideline to negotiate with component manufacturers on RSS requirements;

  3. intended to allow the planning of an RSS process in house to meet reliability requirements or to allow the re-qualification of components for specific, upgraded, environments;

  4. intended as a guideline to sub-contractors who provide RSS as a service.

This document is not intended to provide test plans for specific components or for delivery of certificates of conformance for batches of components.

The use of bi-modal Weibull analysis to select and optimize an RSS process without having to estimate the reliability and life time of all items is described.
