For AI in products such as medical devices or lifts, the body already notified under that sector's law assesses the AI requirements as well.

    Because we did not fully apply the harmonised standards, our face-matching system needs a notified body.

Origin

A long-standing institution of EU product-safety law under the New Approach (1985) and the New Legislative Framework (2008), used for medical devices, machinery and toys; the AI Act (2024) created a notification route for AI. The 2026 Digital OmnibusDigital Omnibus, prop. n.: A European Union package, proposed in 2025, that simplified and delayed parts of its digital rules — above all pushing back the strictest requirements of the EU AI Act by more than a year. introduced a single application and joint assessment for bodies designated under both the AI Act and sectoral law.

Usage note

Notified bodies are usually private testing and certification firms paid by the providers they assess, a model critics see as a potential conflict of interest.
