Notified Body

Independent organization designated to assess conformity of certain high-risk AI systems.

How the laws define this

National frameworks and European Union regulations consistently define a notified body as an authorized independent or third-party entity designated by national authorities to conduct conformity assessments—such as auditing technical documentation, testing, inspection, and issuing certificates—to verify compliance before market entry. While most sources, including Regulation (EU) 2024/1689 (which applies in Estonia as EU regulation) and Zákon č. 318/2025 Z. z., limit these assessment duties strictly to high-risk AI systems, Regulation (EU) 2023/1230 on machinery applies the mandate to high-risk machinery products. The definitions also diverge regarding organizational classification and specific designating entities: the Amendments to the Law on Information Society Services explicitly allows public, private, or academic bodies and names the Innovation Agency as the national notifying authority, whereas the Law of 20 December 2024 specifically requires an accredited third-party organisation operating under statutory confidentiality and procedural standards set by a general notifying authority.

Definitions (8)

A body designated under national procedures and notified to the Commission to carry out conformity assessment activities for high-risk AI systems, including auditing technical documentation and issuing certificates where required; notified bodies operate under oversight of notifying authorities.

An organisation formally designated under the national framework to carry out conformity‑assessment procedures (including ex ante checks) for high‑risk AI systems and to issue conformity certifications in accordance with the AI Act and national implementing measures.

An entity authorized to carry out conformity assessment of high‑risk AI systems, whose involvement may be coordinated by the competent authority and which aligns assessment practices with EU delegated and implementing acts to support market access.

A conformity assessment body (public, private or academic) that has been assessed, designated, and notified by the national notifying authority (Innovation Agency) to carry out conformity assessments of high-risk AI systems in accordance with harmonised procedures and public registry requirements.

An organisation authorised by the national notifying authority (the Innovation Agency) to perform conformity assessment and certification activities for high‑risk AI systems in accordance with EU AI Act procedures. Notified bodies are evaluated under national technical procedures and may be proposed for notification into the EU conformity assessment network.

An accredited third‑party conformity assessment organisation authorised by the notifying authority to perform conformity assessments and issue attestations for high‑risk AI systems in accordance with the AI Act and national implementing rules. Notified bodies are supervised by the notifying authority and must meet accreditation, procedural and confidentiality standards set out in the implementing framework.

A Notified Body is an independent third-party organization designated by a Member State to carry out conformity assessment tasks, such as testing, inspection, and certification, for products falling under specific EU legislation. For certain high-risk machinery under the EU Machinery Regulation, third-party assessment by a Notified Body is mandatory.

Notified bodies are independent third-party organizations designated by national authorities to carry out conformity assessment tasks for high-risk AI systems. Their role is to verify that these systems meet the required safety, ethical, and technical standards before being placed on the market.

Not to be confused with

Conformity Assessment

Conformity assessment is the process verified by notified bodies, while notified body is the designated organization performing that verification for high-risk AI systems.

High-Risk AI System

High-risk AI system is the AI posing significant risks that requires assessment by a notified body, not the assessing organization itself.

CE Marking

CE marking is the conformity mark resulting from successful assessment, while notified body conducts the assessment leading to it.
