EU AI Act Harmonised Standards

Harmonised standards in support of Regulation (EU) 2024/1689 (AI Act): standardisation request M/593 as replaced by M/613, and Commission Implementing Decision (EU) 2026/2274

Status tracker for the European technical standards that let high-risk AI providers prove AI Act compliance. The first one, EN 18286 on quality management, was cited in the Official Journal on 14 Oct 2026; the rest are still in progress.

Summary

  • What they are: EU-endorsed technical standards. If a provider follows a harmonised standard whose reference is published in the Official Journal (OJ), it is presumed to meet the matching AI Act requirements (Art. 40). Using them stays voluntary; providers may prove compliance another way.
  • Who writes them: CEN and CENELEC, through Joint Technical Committee JTC 21 (set up June 2021), at the Commission's request.
  • The request: first issued in May 2023 as C(2023)3215 (M/593). Replaced on 23 Jun 2025 by C(2025)3871 (M/613), updated to match the final AI Act text. The Commission lists ten areas: risk management, data governance and quality, record keeping, transparency, human oversight, accuracy, robustness, cybersecurity, quality management and conformity assessment.
  • Delays: the drafts ran late. In Oct 2025 CEN and CENELEC adopted exceptional fast-track measures (publish after a positive enquiry vote without a separate formal vote; a small drafting group to finish six of the most delayed drafts), targeting availability by Q4 2026. The original April 2025 delivery deadline is reported only by secondary sources.
  • Status on 19 Oct 2026: one harmonised standard cited. Implementing Decision (EU) 2026/2274 (adopted 12 Oct, published and in force 14 Oct 2026) lists EN 18286:2026, Artificial intelligence, Quality management system for EU AI Act regulatory purposes. It gives presumption of conformity for the Art. 17 QMS requirements it covers. The other nine areas have no cited standard yet; the Commission says more are expected to follow.

Who it applies to

  • Mainly providers of high-risk AI systems placing them on the EU market, including non-EU providers (the AI Act reaches them through Art. 2). Hence extraterritorial: true, inherited from the AI Act.
  • Notified bodies and market surveillance authorities use them as the reference for assessments.

Penalties and enforcement

  • No penalty for not using a standard. The AI Act's own fines (see EU AI Act) apply if the legal requirement is not met.
  • Without a cited standard, a provider must show compliance through its own technical documentation, which a notified body or authority can challenge more easily.

Glossary

  • Harmonised standard: a European standard made at the Commission's request; once its reference is in the OJ it gives presumption of conformity.
  • Presumption of conformity: authorities assume you comply with the covered requirement unless they prove otherwise.
  • CEN-CENELEC JTC 21: the joint European committee drafting AI standards.
  • Standardisation request (M/593, M/613): the Commission's formal order to the standards bodies, listing what to write.
  • prEN / EN: draft European Norm / final European Norm.
  • QMS: quality management system; Art. 17 of the AI Act requires one for high-risk providers.

Key takeaways

  • One harmonised standard cited so far: EN 18286:2026 (AI QMS), OJ 14 Oct 2026 via Decision (EU) 2026/2274.
  • The other nine requested areas have no cited standard yet; no dates are stated officially.
  • The request is now M/613 (C(2025)3871, 23 Jun 2025), which repealed M/593.
  • The Omnibus fixed high-risk dates (2 Dec 2027, 2 Aug 2028), so standards delays no longer shift deadlines.
