Cooperation with market surveillance authorities The competent national market surveillance authority of a Member State of the European Union or Switzerland may, on reasoned request, ask the relevant economic operators in the European Union and in Switzerland to provide all the information and documentation necessary to demonstrate the conformity of equipment with the legislation in section I. That authority may contact the economic operator established within the territory of the other Party either directly or with the assistance of the competent national market surveillance authority of the other Party. It may request manufacturers or, where applicable, authorised representatives and importers to provide the docu mentation in a language easily understood by that authority. It may request the economic operators to cooperate on any action taken to eliminate the risks posed by the equipment.
