The European Commission publishes the first harmonised standard under the AI Act, a quality-management standard for providers of high-risk AI

The European Commission said on 19 October that it “has published the reference to the first harmonised standard supporting the implementation of the AI” Act. The standard is EN 18286:2026, a quality-management system for EU AI Act purposes, drawn up by the European standards bodies CEN and CENELEC and cited through Commission Implementing Decision (EU) 2026/2274.

It covers Article 17 of the Act, the quality-management system that providers of high-risk AI systems must run. The Commission says it is built around the AI system's life cycle and can sit on top of existing standards such as ISO/IEC 42001, ISO 9001 or ISO 13485. A provider that applies it is presumed to meet the Article 17 requirements it covers. “It is the only AI QMS standard with a presumption of conformity,” the Commission says.

Applying standards remains voluntary, its standardisation page says, but “Companies that apply harmonised standards are presumed to be compliant with the legal requirements.” The Commission calls the publication a milestone ahead of the high-risk rules and says more harmonised standards are expected.

Nemko, a testing firm, reports that the decision appeared in the Official Journal on 14 October. The Official Journal page came back blank to us, so that date is not confirmed from the issuer.

For companies selling high-risk AI in Europe, this is the first harmonised route to show they comply with part of the Act.
