The first is AI that is a safety component of a product, or is itself a product, covered by the EU laws in Annex I and needing a third-party conformity assessment, such as some medical devices or machinery. The second is AI used in the areas listed in Annex III, such as biometrics, critical infrastructure, education, employment, access to essential services like credit and insurance, law enforcement, migration and justice."],["An Annex III system can fall outside the class under Article 6(3) if it does not pose a significant risk, for example because it only does a narrow procedural task.
