Does ISO 42001 or NIST AI RMF cover this duty?
Requirement-level mappings from Shieldra's crosswalk pack (v2026.07.30). Partial mappings contribute evidence but deliberately do not count as coverage.
| Mapped requirement | Strength | Why (and what’s missing) |
|---|---|---|
| ISO/IEC 42001 A.8 | Partial | A.8 user-information processes are the natural home for interaction disclosure, but Art. 50(1) requires a specific in-product notice at or before first interaction. |
| NIST AI RMF MEASURE-2.8 | Partial | MEASURE 2.8 examines whether users can tell they are interacting with AI; Art. 50(1) requires actually building that disclosure into the product. |
