  "title": "EU AI Act (EU) 2024/1689 - Article 40: Harmonised Standards and Presumption of Conformity for High-Risk AI Systems",
  "domain": "AI Governance & Law",
  "version": "2.0",
  "last_updated": "2026-05-09",
  "bluf": "Article 40 establishes the presumption of conformity mechanism for high-risk AI systems: a system that complies with harmonised European standards (EN standards) published in the Official Journal of the EU is presumed to conform with the corresponding EU AI Act requirements covered by those standards. This is the primary conformity pathway for providers who want to avoid the cost and time of notified body assessment for requirements covered by harmonised standards. The European Commission mandates CEN/CENELEC to develop AI-specific harmonised standards. Where harmonised standards do not yet exist, providers may rely on Commission-adopted Common Specifications per Article 41. Standards applicable to other EU legislation (e.g., ETSI EN 303 645 for IoT cybersecurity) may also contribute to presumption of conformity for overlapping requirements.",
