ISO 26262-8:2018 Clause 13 evaluates eligible hardware developed outside ISO 26262 for its intended safety-related application, focusing on systematic-fault suitability. The integrator establishes random-fault suitability at the next design level; common failure-mode obligations still apply. Does ASIL determine the element class? No. Classes I, II and III depend on verification difficulty, available implementation information and the role of internal safety mechanisms. ASIL still matters to the allocated safety requirements and other lifecycle obligations.

After the course ## What you’ll be able to do ### Assess Clause 13 applicability Use development history and intended use to identify the relevant evaluation route. ### Classify the hardware element Consider behavior, available information and internal safety mechanisms. ### Evaluate the evidence Explain what analysis, tests and operational data support and where gaps remain. ### Document the evaluated scope Record pass/fail results, verification findings and integration restrictions.

Explore the lesson Built for ## Who this guide is for - Engineers evaluating existing hardware - Suppliers preparing application-specific evidence - Safety managers planning reuse - Reviewers checking evaluation arguments ## Frequently Asked Questions Common questions about Hardware Element Evaluation Not merely because it was developed separately. SEooC development follows ISO 26262 under assumed requirements and context. Clause 13 addresses existing hardware developed outside that lifecycle. No. It provides educational explanations and fictional examples. Use the applicable licensed standards and application evidence for engineering decisions; the figures are not certification or release tools. Ten chapters cover scope, classification, element definition, evaluation, analysis, SEooC distinctions, evidence, documentation, three fictional scenarios and practical review recommendations. ## Stuck on this in your project?
