    AI Act Technical Documentation (Annex IV)

    The information set a provider must maintain to demonstrate a high-risk AI system's compliance with Articles 8 to 15.

    Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed July 25, 2026

    Definition

    Article 11 and Annex IV require providers of high-risk AI systems to prepare and keep up to date technical documentation covering system description, design specification, monitoring and control, risk management, training and testing data (methodology, provenance, labelling, cleaning), validation and testing procedures, cybersecurity, and the post-market monitoring plan.

    What this means in practice

    For medical devices, Annex IV elements fold into the MDR Annex II or IVDR Annex II technical documentation rather than sitting in a separate file. Data-governance evidence (Article 10) is the section most often underdeveloped in existing device technical files.
    Common pitfalls
    • Treating Annex IV as boilerplate. Notified bodies specifically probe training-data provenance and labelling processes.
