Annex IV of the EU AI Act sets out the technical documentation that providers of high-risk AI systems must compile and keep up to date, covering system description, design choices, data governance, risk management and post-market monitoring.
In practiceAnnex IV is the backbone of the conformity assessment regime. It tells a provider what an auditor, market surveillance authority or notified body will expect to see on file before a high-risk system is placed on the EU market. Practitioners often underestimate the data governance and human oversight sections, which require evidence rather than narrative. The documentation must remain current for the operating life of the system, not only at launch.
A manufacturer deploying a computer vision quality control system compiles an Annex IV pack covering the training data sources, validation metrics, intended purpose, foreseeable misuse and the procedures used to monitor accuracy in production.
