Hardware Qualification & Evaluation

Hardware element evaluation, defined in ISO 26262-8 Clause 13, is the qualification route for using existing hardware elements - components, sensors, or assemblies not originally developed to ISO 26262 - in safety-related applications. Instead of redeveloping the element, you define its boundaries and usage context, analyze its failure behavior, and collect evidence that it performs its safety-relevant functions with adequate integrity in that context. The depth of analysis, testing, and documentation scales with the ASIL of the requirements the element supports, and the result feeds into the item-level safety case.

Clause 13 targets hardware elements that already exist and whose behavior can be characterized from data sheets, analysis, testing, and field history - typical candidates are standard components, sensors, and intermediate assemblies with stable designs. It is not a shortcut for complex new developments where systematic capability must be built in from the start. The course opens with exactly this decision: the overview and framework chapters lay out the element types, benefits, challenges, and success factors, and the evaluation process chapter provides a decision framework with criteria for concluding whether qualification is viable.

Both approaches deal with elements developed apart from a specific item, and both stand or fall on assumption management. A Safety Element out of Context is developed to ISO 26262 against assumed requirements and an assumed context, validated at integration. A Clause 13 evaluation starts from an element that was not developed to the standard and builds confidence through analysis and evidence. The SEooC parallels chapter transfers the useful discipline - explicit context assumptions, integration strategy, validation of assumptions at integration time - into the qualification workflow and into the safety case.

The evidence chapter organizes this into a systematic framework: evidence types and sources (design data, analyses such as FMEA and FTA, reliability figures, test results, field experience), a quality assessment framework for judging whether each piece is credible and applicable to your usage context, and a structured collection process with traceability from claim to evidence. Documentation then follows ASIL-dependent depth requirements, with defined document structures, templates, configuration management, and a review and approval process, so the package is assessable rather than a folder of loosely related reports.

The course has 10 chapters: an evaluation overview, the ISO 26262-8 Clause 13 framework, element definition and boundaries, the six-phase systematic evaluation process, technical analysis methods, SEooC parallels, evidence collection and assessment, documentation and reporting, three automotive case studies (ESC module, radar sensor assembly, airbag control unit), and industry best practices with common pitfalls. The case studies close with the patterns and insights that repeat across very different component types.
