Overview

Choose the assessment route from the reason the system is high-risk. Annex III points 2-8 use internal control. Point 1 biometric systems can use that route only when Article 43 standards conditions are met. Annex I Section A products follow their product-law procedure. A notified body is an authorised independent assessor. The route determines whether you need one.

Section 1

Choose the route from the high-risk classification

Write down why the system is high-risk. Product-linked systems and Annex III use cases follow different assessment routes. That decision determines the evidence needed and whether a product-law assessor can assess the AI requirements.

For product-linked systems under Article 6(1), the AI system is high-risk when it is a safety component, or is itself a product, covered by Annex I Union harmonisation legislation and that product is already subject to third-party under that legislation.

For Annex III systems, Article 43 generally points to internal control, with a narrower notified body route for point 1 Annex III systems in the conditions listed in Article 43(1).

Check the application date separately from the route. Regulation (EU) 2026/1744 was published on 24 July 2026 and enters into force on 27 July 2026. It applies Chapter III Sections 1-3, except Article 6(5), from 2 December 2027 for Annex III high-risk systems and from 2 August 2028 for Article 6(1) systems.

For Article 6(1) systems related to products under Annex I Section B, the amendment limits direct AI Act application to Article 6(1), Article 60a, and Articles 102-112; Articles 57-59 apply only where the high-risk requirements have been integrated into the sector law.

Record the exact Annex I instrument before selecting an AI Act conformity route.

  • Record the high-risk legal basis: Article 6(1) product route or Article 6(2) Annex III route.
  • For Annex III, identify the exact Annex III point and whether Article 6(3) non-high-risk reasoning is being used; if so, document the assessment before market release and register under Article 49(2).
  • For Annex III point 1 systems, check whether harmonised standards or common specifications fully cover the relevant Section 2 requirements and whether they have been applied without restriction.
  • For Annex I Section A systems, integrate the applicable AI Act requirements into the product-law . For Section B products, first apply the amended Article 2(2) limit on direct AI Act duties and identify the sector-law procedure.
Section 2

What to check under internal control

Under Annex VI internal control, the provider checks three things: the quality management system meets Article 17; the technical file demonstrates Chapter III Section 2 compliance; and design, development and monitoring after release match that file.

Connect the Section 2 requirements to system design and operating controls: risk management, data governance, technical documentation, logging, deployer information, human oversight, accuracy, robustness, and cybersecurity. Keep the system evidence as well as any policy or supplier statement.

  • Keep an Article 17 quality management file covering regulatory strategy, design control, validation, data management, risk management, post-market monitoring, serious incident reporting, communications, record keeping, resources, and accountability.
  • Keep Article 11 and Annex IV technical documentation with intended purpose, versions, interfaces, architecture, datasets, validation and testing reports, human oversight measures, cybersecurity measures, standards or common specifications, declaration of conformity, and post-market monitoring plan.
  • Keep the internal-control conclusion as a traceable sign-off that names the applied standards or common specifications and explains any alternative technical solution.
  • Store provider logs where the provider controls them and align the log design with post-market monitoring and substantial-modification detection.
Section 3

When an independent assessor is required

An Annex III point 1 biometric system needs a notified body when the Article 43 standards conditions for internal control are not met. Triggers include missing standards or common specifications, partial standards use, unused common specifications and restrictions on a relevant part of a cited standard.

For high-risk AI systems covered by Annex I Section A product legislation, Article 43(3) sends the provider to the procedure required by that product law.

Notified bodies notified under those product laws may control conformity with AI Act Section 2 requirements if their compliance with specified AI Act notified-body requirements has been assessed in the relevant notification procedure.

Those sector-law notified bodies must apply for designation under AI Act Chapter III Section 4 by 28 January 2028; keep that application requirement with the assessor qualification record.

Amended Article 43(3) also requires assessment of Article 17 quality management and preserves the sector-law procedure when the system is also an Annex III use case.

A product does not need a third-party assessment solely because it includes a high-risk AI safety component if the relevant Section A legislation does not require that procedure.

When Annex VII applies to a system intended for use by law-enforcement, immigration, or asylum authorities, or by Union institutions, bodies, offices, or agencies, the relevant market surveillance authority acts as the notified body. Do not route those systems to an ordinary commercial notified body.

Check whether amended Article 75 assigns the system to the AI Office before selecting the assessor. For high-risk systems within that competence that require third-party assessment, the AI Office is responsible for the assessment and entrusts the work to designated notified bodies acting on the Commission's behalf.

Record that authority route instead of assuming the provider can engage any commercial assessor.

  • Prepare a notified-body application package with the provider details, covered AI systems, Article 17 quality management documentation, Annex IV technical documentation, and a declaration that the same application has not been lodged with another notified body.
  • Expect the notified body to examine the quality management system, examine technical documentation, request evidence or tests, and, where necessary and proportionate to its task, access training, validation, and testing datasets.
  • Treat model or system changes that could affect compliance or intended purpose as notified-body change events when a Union technical documentation assessment certificate has been issued.
  • Keep refusals, restrictions, suspensions, withdrawals, certificates, supplements, audit reports, and reasoned assessment decisions with the product release evidence.
Section 4

Complete declaration, marking and registration

The provider owns the pre-release checks under Article 16: system compliance, quality management, documentation, assessment, EU declaration of conformity, CE marking and registration where Article 49 requires it.

Article 47 and Annex V require a declaration for each high-risk AI system, issued under the provider's sole responsibility. It must identify the system, the provider or authorised representative, applicable Union law, relevant standards or common specifications, and, where applicable, the notified body, procedure, and certificate.

  • Before release, confirm the EU declaration of conformity exists, is up to date, and can be provided to national competent authorities on request.
  • Affix CE marking visibly, legibly, and indelibly; for digital high-risk AI systems, use a digital CE marking only if it is easily accessible through the interface or another accessible electronic means.
  • Where a notified body was involved, include the notified body's identification number after the CE marking and in promotional material that refers to CE conformity.
  • Register providers and relevant high-risk AI systems in the EU database before placement on the market or putting into service where Article 49 requires registration.
Section 5

Who authorises the assessor?

Member State notifying authorities assess, designate, notify and monitor bodies. They must avoid conflicts of interest and act objectively and impartially. They decide which bodies can act as notified bodies and oversee their work.

A notified body is the body that has been notified and may perform the notified-body assessment tasks within the scope of its notification.

Article 31 requires notified bodies to be independent of providers and other economically interested operators, to avoid consultancy conflicts, to maintain confidentiality, and to have sufficient administrative, technical, legal, and scientific personnel for the relevant AI systems, data, computing, and AI Act requirements.

  • Use the notifying authority route for questions about designation, notification scope, monitoring, objections, or competence of a body.
  • Use the notified body route for assessment of the provider's quality management system, technical documentation, certificates, supplements, surveillance audits, and certificate changes.
  • Check the notified body's notification scope against the AI system type and conformity module before treating a certificate as applicable.
  • Use the Commission Single Market Compliance Space/NANDO-style listing to locate notified bodies by legislation as designations become available.
Section 6

Check what standards actually cover

EN 18286:2026 covers provider quality management for AI Act purposes. Decision (EU) 2026/2274 cited it in the Official Journal on 14 October 2026. From that date, its relevant normative clauses support a presumption of conformity for the requirements they cover. The citation does not change application dates.

Annex ZA maps the standard to Article 17(1) quality-management requirements and the first sentence of Article 11(1), with conditions. Technical documentation must contain all Annex IV elements; the QMS must document Article 17(1)(a)-(m), and its risk-management system must comply with Article 9.

Article 17(2)-(4) remain outside the standard's coverage and need separate treatment where applicable.

EN 18286 alone does not cover all Chapter III Section 2 requirements or establish entitlement to Annex VI internal control for Annex III point 1 biometrics. Check the standards or common-specification coverage for every relevant Section 2 requirement before choosing that route.

Where Annex VII applies, the notified body still assesses the QMS and system technical documentation. Use the harmonised standards and quality-management guide to connect each procedure to evidence.

Check which applicable AI Act requirements each technical standard covers. A harmonised standard creates a presumption of conformity only after its reference is published in the Official Journal and only for the requirements covered by that reference.

A draft standard, an ISO or ETSI publication, or a standard used elsewhere in the organisation does not receive that legal effect automatically.

Common specifications are Commission acts used under the conditions in Article 41. Providers can use other technical solutions, but they must justify how those solutions meet an equivalent level of compliance. Codes of practice and Commission or standards-body guidance can organise evidence without replacing the binding requirement or the conformity route.

  • For each cited standard, record the edition, clause, AI Act requirement supported, Official Journal reference if any, date checked, applicable system version, test evidence, and uncovered residual requirement.
  • Treat ISO/IEC 42001 as management-system evidence and ISO/IEC 23894 as risk-management guidance unless a specific legal mechanism gives a provision a different effect.
  • Use ETSI AI security, data-supply-chain, privacy, transparency, and explicability material as technical input where it fits the system; label it as supporting evidence unless the relevant provision has acquired a formal presumption of conformity.
  • Recheck the standards register before and after a new Official Journal citation, common specification, system change, or certificate update.
Section 7

Check the file before release

Before release, check whether the file lets an authority, assessor, importer, distributor or customer understand the chosen route and verify its evidence. Keep the decision and supporting records together.

Escalate the file for legal and regulatory review when the route depends on Annex I product law, Annex III point 1 conditions, partial standards coverage, a restricted harmonised standard, non-application of common specifications, a substantial modification, or a notified-body refusal or restriction.

Article 46 permits a market surveillance authority, on a duly justified request and for a limited period, to authorise a specific high-risk system before is complete for exceptional public-security, life and health, environmental, or key industrial and infrastructure reasons.

The authority controls this exceptional authorisation; the conformity procedure must still be completed without undue delay. For systems covered by Annex I Section A product legislation, Article 46(7) instead limits the derogation to the one available under that product law.

Does every high-risk AI system need a notified body?

No. Article 43 uses internal control for high-risk AI systems in Annex III points 2 to 8. Notified body involvement is triggered for Annex III point 1 systems in the conditions listed in Article 43(1), and Annex I product systems follow the relevant product-law route.

What evidence should a provider keep after ?

Article 18 requires providers to keep, for 10 years after placement on the market or putting into service, technical documentation, quality management documentation, approved notified-body change records where applicable, notified-body decisions and documents where applicable, and the EU declaration of conformity.

What changes can reopen ?

Article 43 requires a new after a substantial modification. For systems with a Union technical documentation assessment certificate, Annex VII also requires provider notice to the issuing notified body for changes that could affect compliance or intended purpose.

  • High-risk basis is recorded with Article 6 reasoning and, where relevant, the exact Annex III point or Annex I product legislation.
  • Article 43 route decision is written: Annex VI internal control, Annex VII notified-body assessment, or product-law conformity route.
  • Article 17 quality management documentation and Article 11/Annex IV technical documentation are complete enough to demonstrate Section 2 compliance.
  • EU declaration of conformity, CE marking decision, notified body certificate details where applicable, and Article 49 registration evidence are stored together.
  • Change-control rules identify when a new , notified-body supplement, or updated declaration is needed. For a system that continues to learn, Article 43(4) excludes changes predetermined at the initial conformity assessment and included in the technical documentation from substantial modification; retain the documented limits of that planned change.
