ISO 21448:2022 — Safety Of The Intended Functionality (SOTIF)

# ISO 21448:2022 — Safety Of The Intended Functionality (SOTIF) — 45% of in-scope requirements covered.

6 requirements · 5 in scope (4 designed · 1 advisory) · 1 out-of-scope (outside KYE™’s authority layer). The 45% is weighted over the in-scope base.

**Source:** ISO 21448:2022 — Road vehicles: Safety of the intended functionality. The companion to ISO 26262: where ISO 26262 governs safety in the presence of faults, SOTIF governs the residual risk arising when a fault-free intended function (e.g. an ADAS / autonomous perception or decision function) behaves unsafely at the edge of, or outside, its specified operating envelope (performance limitations, foreseeable misuse, triggering conditions). KYE™ governs the AUTHORITY, the operating-envelope (control / safety-floor) admissibility, the EVIDENCE and the FINALITY of an AI-recommended action against a declared intended-functionality envelope; KYE™ does NOT perform the hazard analysis, the scenario / triggering-condition identification, nor the model's internal failure-mechanism analysis. Starter requirement set grafted from the functional-safety spine (IEC 61508 / IEC 61511); deepen by graft per the Foundry productisation template. · **License:** ISO — standard text is copyrighted; KYE™ registry paraphrases each requirement's intent and cites the official clause identifier for mapping purposes only.

## By category

| Category | Reqs | Enforced | Designed | Advisory | Deferred | Coverage |
| --- | --- | --- | --- | --- | --- | --- |
| Clause 5-6 — Functional & SOTIF specification | 2 | 0 | 2 | 0 | 0 | **50%** |
| Clause 7-8 — Triggering conditions & known/unknown scenarios | 2 | 0 | 0 | 1 | 0 | **25%** |
| Clause 10-11 — Verification, validation & decision evidence | 2 | 0 | 2 | 0 | 0 | **50%** |
