In order to facilitate a smooth, effective and harmonised implementation of this Regulation a European Artificial Intelligence Board should be established. The Board should reflect the various interests of the AI eco-system and be composed of representatives of the Member States. The Board should be responsible for a number of advisory tasks, including issuing opinions, recommendations, advice or contributing to guidance on matters related to the implementation of this Regulation, including on enforcement matters, technical specifications or existing standards regarding the requirements established in this Regulation and providing advice to the Commission and the Member States and their national competent authorities on specific questions related to artificial intelligence. In order to give some flexibility to Member States in the designation of their representatives in the AI Board, such representatives may be any persons belonging to public entities who should have the relevant competences and powers to facilitate coordination at national level and contribute to the achievement of the Board’s tasks. The Board should establish two standing sub-groups to provide a platform for cooperation and exchange among market surveillance authorities and notifying authorities on issues related respectively to market surveillance and notified bodies. The standing subgroup for market surveillance should act as the Administrative Cooperation Group (ADCO) for this Regulation in the meaning of Article 30 of Regulation (EU) 2019/1020. In line with the role and tasks of the Commission pursuant to Article 33 of Regulation (EU) 2019/1020, the Commission should support the activities of the standing subgroup for market surveillance by undertaking market evaluations or studies, notably with a view to identifying aspects of this Regulation requiring specific and urgent coordination among market surveillance authorities. The Board may establish other standing or temporary sub-groups as appropriate for the purpose of examining specific issues. The Board should also cooperate, as appropriate, with relevant EU bodies, experts groups and networks active in the context of relevant EU legislation, including in particular those active under relevant EU regulation on data, digital products and services.
