In the framework of the Conformity & Interoperability Programme, conformity and interoperability assessment studies are being conducted in the Regions. These studies aim to identify all the necessary elements to promote collaboration among regional and sub-regional organizations for establishing a common Conformity & Interoperability Regime through Mutual Recognition Agreements (MRA) and/or regional test centres, as appropriated. Possible scenarios to meet Member States and Regions needs on Conformity & Interoperability are presented.
