Article 22 requires economic operators to identify, on request of competent authorities, any other economic operator that supplied them with a device + to whom they have supplied a device, for 10 years. Article 23 references the medical devices nomenclature (the EU's harmonised vocabulary). Article 24 establishes the Unique Device Identification (UDI) system: every IVD (except custom-made + investigational) carries a UDI consisting of a UDI-DI (device identifier) + UDI-PI (production identifier where relevant); class-A devices have a UDI on the packaging only. Article 25 governs the central UDI database within EUDAMED.
